WEBVTT - From the Book of Sand

0:00:03.040 --> 0:00:06.800
<v Speaker 1>Welcome to Stuff to Blow Your Mind, a production of iHeartRadio.

0:00:13.080 --> 0:00:15.440
<v Speaker 2>Hey, welcome to Stuff to Blow your Mind. My name

0:00:15.480 --> 0:00:16.000
<v Speaker 2>is Robert.

0:00:15.880 --> 0:00:19.120
<v Speaker 3>Lamb, and I'm Joe McCormick. And hey, if you're watching

0:00:19.120 --> 0:00:22.160
<v Speaker 3>on video, obviously we are not in our normal places,

0:00:22.200 --> 0:00:25.400
<v Speaker 3>not coming to you from the Gray Matt underworld or

0:00:25.840 --> 0:00:28.360
<v Speaker 3>the other world, I can't remember what we decided to

0:00:28.360 --> 0:00:31.319
<v Speaker 3>call it, the places we usually come from. Today we

0:00:31.360 --> 0:00:35.519
<v Speaker 3>are recording remotely at the studio at Baja Mar because

0:00:35.520 --> 0:00:37.200
<v Speaker 3>they are a sponsor of this episode.

0:00:37.360 --> 0:00:40.720
<v Speaker 4>That's right, we're in the Bahamas. I made a point

0:00:40.880 --> 0:00:43.680
<v Speaker 4>of walking in the sand on the beach before I

0:00:43.720 --> 0:00:45.280
<v Speaker 4>came in here today because we are going to be

0:00:45.320 --> 0:00:48.159
<v Speaker 4>talking about sand. I kind of like to tie these

0:00:48.240 --> 0:00:51.800
<v Speaker 4>kind of things together when there's some travel involved. I'm

0:00:51.800 --> 0:00:54.200
<v Speaker 4>also you can't see it, but I am wearing flip flops.

0:00:54.200 --> 0:00:57.840
<v Speaker 4>It felt appropriate. It felt like Jimmy Buffett would want

0:00:57.840 --> 0:01:00.720
<v Speaker 4>me to wear flip flops for this recording, so I

0:01:00.760 --> 0:01:02.319
<v Speaker 4>honor his spirit in doing so.

0:01:02.800 --> 0:01:03.800
<v Speaker 3>Stuff on a pop top.

0:01:03.880 --> 0:01:06.920
<v Speaker 4>Yet fortunately not and you don't want to engineer that.

0:01:06.920 --> 0:01:11.560
<v Speaker 4>That's you know, it ruins the magic of it, of course. Yeah,

0:01:11.600 --> 0:01:13.920
<v Speaker 4>So yeah, we're going to talk about sand here today,

0:01:14.200 --> 0:01:18.360
<v Speaker 4>and I think sand is a great topicause in in general,

0:01:18.480 --> 0:01:21.399
<v Speaker 4>I think a lot of people have certain feelings about it,

0:01:22.360 --> 0:01:26.640
<v Speaker 4>you know, in the imagination, but also very personal opinions

0:01:26.680 --> 0:01:30.080
<v Speaker 4>about sand. I don't know about you, Joe. I enjoy

0:01:30.120 --> 0:01:32.440
<v Speaker 4>the sand. I don't like sand where it's not supposed

0:01:32.480 --> 0:01:36.600
<v Speaker 4>to be. But I like going into a region of sand,

0:01:36.680 --> 0:01:39.200
<v Speaker 4>experiencing the sand. I like the feeling of walking on

0:01:39.240 --> 0:01:42.920
<v Speaker 4>a beach and feeling it, you know, move beneath my toes,

0:01:43.080 --> 0:01:47.440
<v Speaker 4>getting the different consistencies of sand. I like digging in

0:01:47.480 --> 0:01:51.160
<v Speaker 4>the sand. But I also know plenty of people who

0:01:51.200 --> 0:01:54.680
<v Speaker 4>are like an absolute no to beach time because they

0:01:54.760 --> 0:01:57.560
<v Speaker 4>just don't like sand. I mean, Star Wars memes aside,

0:01:57.560 --> 0:01:58.680
<v Speaker 4>They just they just don't like it.

0:01:58.720 --> 0:02:02.040
<v Speaker 3>And it goes everywhere I feel about the sand the

0:02:02.080 --> 0:02:06.680
<v Speaker 3>way I feel about sweat, which is I like being

0:02:06.760 --> 0:02:09.799
<v Speaker 3>sweaty when you're supposed to be sweaty, and I hate

0:02:09.880 --> 0:02:12.200
<v Speaker 3>being sweaty when you're not supposed to be sweaty. There

0:02:12.240 --> 0:02:14.280
<v Speaker 3>you go, you know, working up a sweat when you're

0:02:14.280 --> 0:02:17.240
<v Speaker 3>exercising feels great. Working up a sweat when you're like

0:02:17.800 --> 0:02:21.080
<v Speaker 3>getting dressed ready to go out somewhere is like the

0:02:21.120 --> 0:02:24.320
<v Speaker 3>worst feeling. Yeah, and sand. Yeah, it's like when you're

0:02:24.360 --> 0:02:27.280
<v Speaker 3>at the beach, there's nothing better. Actually, I like, literally

0:02:27.320 --> 0:02:30.040
<v Speaker 3>I love the feeling. Most of what I do at

0:02:30.040 --> 0:02:32.680
<v Speaker 3>the beach when I go is just like walk around

0:02:32.680 --> 0:02:33.639
<v Speaker 3>and feel the sand.

0:02:33.440 --> 0:02:33.919
<v Speaker 2>On my feet.

0:02:34.120 --> 0:02:37.440
<v Speaker 3>Yeah that's you know. I'm not a huge swimmer, but

0:02:37.720 --> 0:02:40.520
<v Speaker 3>I do love that. But yeah, getting like sand in

0:02:40.560 --> 0:02:43.040
<v Speaker 3>your shoes or sand in your underwear when you're not

0:02:43.120 --> 0:02:45.120
<v Speaker 3>at the beach, that's not so great.

0:02:45.240 --> 0:02:47.880
<v Speaker 4>Yeah, where the bed is one of the reasons I've

0:02:47.919 --> 0:02:50.240
<v Speaker 4>never even much of a sand camper. I've done a

0:02:50.280 --> 0:02:53.600
<v Speaker 4>little of it, but it's not really my cup of tea,

0:02:53.720 --> 0:02:57.040
<v Speaker 4>just because I have a harder time maintaining that that

0:02:57.800 --> 0:03:01.320
<v Speaker 4>line between the sand world and mine, a non sandy world.

0:03:02.280 --> 0:03:04.480
<v Speaker 4>But still I've had some great times camping on the

0:03:04.480 --> 0:03:05.120
<v Speaker 4>beach as well.

0:03:05.600 --> 0:03:08.080
<v Speaker 3>You know, I was just thinking about how in Dune

0:03:08.480 --> 0:03:12.600
<v Speaker 3>there is so much about the absence and preciousness of water.

0:03:12.760 --> 0:03:18.400
<v Speaker 3>But I was struggling to remember, are there equivalent sentiments

0:03:18.440 --> 0:03:22.360
<v Speaker 3>the characters express about the abundance or over abundance of sand.

0:03:23.080 --> 0:03:27.600
<v Speaker 4>Hmmm, well, I'm trying to remember you've been reading Herbert

0:03:27.639 --> 0:03:28.560
<v Speaker 4>more recently than I have.

0:03:28.880 --> 0:03:32.920
<v Speaker 3>Yeah, though, so now I'm reading Dune Messiah, which I've

0:03:32.919 --> 0:03:36.200
<v Speaker 3>actually never read before, So I'm finally getting into the sequels.

0:03:36.640 --> 0:03:40.000
<v Speaker 3>I'm enjoying it, though I'm aware there are diminishing returns

0:03:40.280 --> 0:03:41.640
<v Speaker 3>as you continue, but.

0:03:41.920 --> 0:03:44.640
<v Speaker 4>It depends if you open your whole heart to it.

0:03:44.920 --> 0:03:47.080
<v Speaker 4>I'm of the opinion there there are gems to be

0:03:47.160 --> 0:03:50.360
<v Speaker 4>found in each of the books, but those the first

0:03:50.400 --> 0:03:52.760
<v Speaker 4>two books are special in my opinion. Well, I I've

0:03:52.840 --> 0:03:55.760
<v Speaker 4>enjoyed them all, but but yeah, there's it's it's different

0:03:55.760 --> 0:03:57.080
<v Speaker 4>once you get into the later books.

0:03:57.120 --> 0:04:00.000
<v Speaker 3>The second book, I've noticed so far there is significantly

0:04:00.160 --> 0:04:04.280
<v Speaker 3>less ecology in it and it is more politics and conspiracy.

0:04:04.480 --> 0:04:04.880
<v Speaker 2>Yeah.

0:04:04.960 --> 0:04:08.600
<v Speaker 4>Yeah, and it's a dark read in its own right. Yeah,

0:04:08.640 --> 0:04:10.520
<v Speaker 4>we will be talking a little bit about done as

0:04:10.520 --> 0:04:13.360
<v Speaker 4>we proceed here. We'll talk a little bit about some technology,

0:04:13.480 --> 0:04:18.800
<v Speaker 4>some FRIM and technology from the frimkit. But yeah, this

0:04:18.880 --> 0:04:21.200
<v Speaker 4>is where I guess we get more into the imagination

0:04:21.400 --> 0:04:26.240
<v Speaker 4>sphere for sand because it does bring up a lot

0:04:26.279 --> 0:04:28.640
<v Speaker 4>of ideas, and so I was thinking, like, what are

0:04:28.680 --> 0:04:30.839
<v Speaker 4>some of the core ideas I keep coming back to

0:04:30.960 --> 0:04:34.279
<v Speaker 4>and I keep seeing and in my readings and things

0:04:34.360 --> 0:04:37.640
<v Speaker 4>I'm watching things I'm thinking about. I think one of

0:04:37.680 --> 0:04:40.200
<v Speaker 4>the big ones that everyone's probably thinking of is, of course,

0:04:40.240 --> 0:04:44.520
<v Speaker 4>sand as the infinite, you know, uncountable grains of sand

0:04:44.640 --> 0:04:47.880
<v Speaker 4>and deserts that stretch beyond sight or on beaches that

0:04:48.040 --> 0:04:51.719
<v Speaker 4>just you know, vanish into the ocean unseen. I think

0:04:51.720 --> 0:04:55.000
<v Speaker 4>of sand through the hour glass. I think of the

0:04:55.440 --> 0:04:59.240
<v Speaker 4>excellent short story The Book of Sand from Hory Lewis

0:04:59.240 --> 0:05:04.360
<v Speaker 4>Borges about a tone of infinite random numbered pages. So

0:05:04.480 --> 0:05:09.000
<v Speaker 4>anytime you you open the book, you'll find different numbers,

0:05:09.040 --> 0:05:11.600
<v Speaker 4>and they might be it might be just a small number,

0:05:11.640 --> 0:05:13.640
<v Speaker 4>colossal number. I think at one point it's like a

0:05:13.760 --> 0:05:17.560
<v Speaker 4>number to the ninth power that the reader finds. And

0:05:17.560 --> 0:05:19.839
<v Speaker 4>and then the script itself is written in some language

0:05:19.839 --> 0:05:22.719
<v Speaker 4>that he can't decipher, and sometimes with a crude image,

0:05:22.720 --> 0:05:25.559
<v Speaker 4>but it is infinite, and you'll never find the same

0:05:25.600 --> 0:05:29.159
<v Speaker 4>page twice. And he fears that if he burns the book,

0:05:29.440 --> 0:05:32.680
<v Speaker 4>it will an infinite book will burn infinitely and just

0:05:32.920 --> 0:05:37.160
<v Speaker 4>you know, cloak the world and smoke smoke. Yeah, so

0:05:37.440 --> 0:05:38.760
<v Speaker 4>you know, I think about stuff like that.

0:05:40.160 --> 0:05:42.400
<v Speaker 3>I read this story last night. Actually, oh you were

0:05:42.400 --> 0:05:43.279
<v Speaker 3>telling me about Yeah.

0:05:43.200 --> 0:05:46.080
<v Speaker 4>It's like three pages long, it's it's it's great. One

0:05:46.120 --> 0:05:48.400
<v Speaker 4>of the things I love about Borhees, He's deep, he's

0:05:48.400 --> 0:05:49.239
<v Speaker 4>often very brief.

0:05:49.560 --> 0:05:52.919
<v Speaker 3>One thing I like about that story is that it begins,

0:05:53.080 --> 0:05:56.159
<v Speaker 3>as with so many Borhees stories, with a traveler arriving

0:05:56.279 --> 0:05:58.960
<v Speaker 3>strange traveler who has an artifact to share with you,

0:05:59.040 --> 0:06:03.200
<v Speaker 3>and then the protagonist greatly desires to acquire the artifact,

0:06:03.240 --> 0:06:06.200
<v Speaker 3>and so in this case, yeah, he becomes entranced because

0:06:06.240 --> 0:06:08.560
<v Speaker 3>he finds a page in the book that has a

0:06:08.640 --> 0:06:11.719
<v Speaker 3>tiny illustration of an anchor on it, and then he

0:06:12.160 --> 0:06:14.120
<v Speaker 3>like turns the pages and then can't ever find the

0:06:14.120 --> 0:06:17.040
<v Speaker 3>anchor again. But yeah, it describes like trying to get

0:06:17.120 --> 0:06:19.920
<v Speaker 3>to the first page and it's impossible because pages just

0:06:20.000 --> 0:06:23.479
<v Speaker 3>keep multiplying towards the covers. You know, it's gotten an

0:06:23.520 --> 0:06:29.200
<v Speaker 3>epigraph to a poem by George Herbert that refers to

0:06:29.320 --> 0:06:31.640
<v Speaker 3>the idea of ropes of sand, you know, a common

0:06:31.680 --> 0:06:35.520
<v Speaker 3>metaphor for something that is like unstable or not substantial.

0:06:36.640 --> 0:06:40.880
<v Speaker 3>But the other metaphor with sand in the story is

0:06:41.000 --> 0:06:43.880
<v Speaker 3>like you're saying the idea of the infinite, that sands

0:06:43.920 --> 0:06:46.599
<v Speaker 3>are infinite, and therefore you know they could they could

0:06:46.600 --> 0:06:48.880
<v Speaker 3>just multiply forever, like the pages of this book. The

0:06:48.880 --> 0:06:51.159
<v Speaker 3>funny thing is, of course, grains of sand are not

0:06:51.240 --> 0:06:55.640
<v Speaker 3>actually infinite. Grains of sand are I perfectly finite. That

0:06:55.760 --> 0:06:59.120
<v Speaker 3>is a countable thing. It's not practically accountable by human beings,

0:06:59.160 --> 0:07:02.720
<v Speaker 3>but in theory is countable. And in fact, you know,

0:07:02.839 --> 0:07:07.799
<v Speaker 3>mathematically speaking, any finite number is infinitely small than infinity.

0:07:07.880 --> 0:07:10.000
<v Speaker 3>So the number of grains of sand in the universe

0:07:10.080 --> 0:07:12.560
<v Speaker 3>is infinitely less than an actual infinity.

0:07:13.000 --> 0:07:16.520
<v Speaker 4>Yeah, yeah, some of you may be thinking of this.

0:07:16.560 --> 0:07:18.640
<v Speaker 4>We're not really going to get into this concept in

0:07:18.640 --> 0:07:22.880
<v Speaker 4>this episode, but Archimedes of course famously tried to figure

0:07:22.880 --> 0:07:24.840
<v Speaker 4>out what was the upper bound for the number of

0:07:24.880 --> 0:07:29.000
<v Speaker 4>sand grains in the universe, So it's you know, he

0:07:29.160 --> 0:07:31.560
<v Speaker 4>was of the mind it can be counted, or at

0:07:31.640 --> 0:07:33.080
<v Speaker 4>least estimated, Yeah.

0:07:32.880 --> 0:07:36.560
<v Speaker 3>Which, you know, and whole like methods of estimation of

0:07:36.600 --> 0:07:39.760
<v Speaker 3>substances like that, I think are a really interesting topic.

0:07:39.800 --> 0:07:41.760
<v Speaker 3>We've talked about on the show before. Long ago we

0:07:41.800 --> 0:07:46.040
<v Speaker 3>did an episode on fermi estimation, remember that, which is

0:07:46.080 --> 0:07:49.800
<v Speaker 3>just like a sort of orders of magnitude based system

0:07:50.360 --> 0:07:54.400
<v Speaker 3>for estimating numbers of uncountable things.

0:07:54.960 --> 0:07:55.200
<v Speaker 2>Yeah.

0:07:55.240 --> 0:08:00.320
<v Speaker 4>Absolutely, And you mentioned sand falling through the fingers passing

0:08:00.320 --> 0:08:03.160
<v Speaker 4>through the fingers. The ephemeral nature of things made out

0:08:03.160 --> 0:08:05.960
<v Speaker 4>of sand, that is I think another major theme you

0:08:05.960 --> 0:08:07.600
<v Speaker 4>see over and over again. Of course, you see it

0:08:07.600 --> 0:08:11.640
<v Speaker 4>in things like sand mondolas or sand castles, you know,

0:08:11.720 --> 0:08:14.520
<v Speaker 4>where you can create this thing of beauty out of

0:08:14.560 --> 0:08:16.520
<v Speaker 4>the sand, but it will not last, and it's not

0:08:16.560 --> 0:08:20.680
<v Speaker 4>supposed to last, and of course neither do we. Let's

0:08:20.680 --> 0:08:23.200
<v Speaker 4>see other ideas. Sand is a varied substance. Of course,

0:08:23.280 --> 0:08:25.560
<v Speaker 4>not all sand is the same. Some of the things

0:08:25.560 --> 0:08:28.640
<v Speaker 4>we call sand, especially when we get off of our planet,

0:08:28.880 --> 0:08:30.720
<v Speaker 4>you get into various discussions about is.

0:08:30.720 --> 0:08:33.120
<v Speaker 2>It sand, is it soil? Is it soil?

0:08:33.400 --> 0:08:35.079
<v Speaker 4>Is it really sand? And you kind of go back

0:08:35.080 --> 0:08:37.160
<v Speaker 4>and forth, and then sometimes people just call it sand.

0:08:37.679 --> 0:08:40.440
<v Speaker 3>Am I correct in understanding that sand is not a

0:08:40.520 --> 0:08:43.080
<v Speaker 3>name for a substance. It's a name for a size

0:08:43.120 --> 0:08:46.280
<v Speaker 3>of particle. Sand is a grit size, right.

0:08:46.320 --> 0:08:49.400
<v Speaker 4>But people can get a little particular, like, for instance,

0:08:49.720 --> 0:08:51.840
<v Speaker 4>we're not really going to get into the hourglass here.

0:08:52.440 --> 0:08:54.079
<v Speaker 4>We might come back and do a full episode in

0:08:54.080 --> 0:08:56.880
<v Speaker 4>the hour glass in the future, but some people will

0:08:56.880 --> 0:08:59.720
<v Speaker 4>point out, well, actually it's not sand in an hour glass,

0:08:59.520 --> 0:09:02.560
<v Speaker 4>it's this particular recipe of particles that works well with

0:09:02.600 --> 0:09:03.320
<v Speaker 4>an hour glass.

0:09:04.120 --> 0:09:06.320
<v Speaker 3>And I guess there are things that might fit the

0:09:06.360 --> 0:09:09.200
<v Speaker 3>definition if you just go by grain size, but nobody

0:09:09.240 --> 0:09:13.600
<v Speaker 3>would call them sand, like would sugar be sand by

0:09:13.720 --> 0:09:15.479
<v Speaker 3>If you just go particles.

0:09:15.240 --> 0:09:16.960
<v Speaker 4>You would get you would get weird looks. If you

0:09:17.000 --> 0:09:19.200
<v Speaker 4>ask for it's like, give me the sweet sand, the

0:09:19.280 --> 0:09:22.040
<v Speaker 4>sand that goes in my coffee. People would ask, who

0:09:22.080 --> 0:09:25.800
<v Speaker 4>is this space aly? But uh, yeah, I mean the

0:09:25.840 --> 0:09:27.640
<v Speaker 4>other thing is, yeah, you have different colors of sand,

0:09:27.840 --> 0:09:30.600
<v Speaker 4>different sistencies of sand, Like digging in the beach. I

0:09:30.600 --> 0:09:32.280
<v Speaker 4>know that like sometimes you have that sand it is

0:09:32.400 --> 0:09:34.960
<v Speaker 4>like a powder, or when it's compacted it's like a

0:09:35.080 --> 0:09:37.520
<v Speaker 4>it's almost like a clay that you can mold. And

0:09:37.559 --> 0:09:41.200
<v Speaker 4>then other times the bits of like shell in the

0:09:41.280 --> 0:09:44.520
<v Speaker 4>sand that it's so like coarse and rough that you

0:09:44.720 --> 0:09:47.360
<v Speaker 4>just like scrape your hands up digging in it, you know,

0:09:48.480 --> 0:09:50.800
<v Speaker 4>but you can't stop because it's what you do at

0:09:50.840 --> 0:09:55.360
<v Speaker 4>the beach. Likewise, digging in the sand, you quickly often realize, well,

0:09:55.360 --> 0:09:57.960
<v Speaker 4>this is this is a thing, this is a world

0:09:57.960 --> 0:10:00.719
<v Speaker 4>that creatures live in as well. You know, you might

0:10:00.800 --> 0:10:04.480
<v Speaker 4>encounter things like periwinkles or sand hoppers. Sand fleas whatever

0:10:04.480 --> 0:10:06.559
<v Speaker 4>you want to call them, or of course the mighty

0:10:06.600 --> 0:10:09.280
<v Speaker 4>sand crabs darting in and out of their little layers,

0:10:10.040 --> 0:10:12.440
<v Speaker 4>and then yeah, and then just back to sand castles

0:10:12.440 --> 0:10:17.000
<v Speaker 4>as well. It's kind of like a very early experiment

0:10:17.080 --> 0:10:21.760
<v Speaker 4>with the idea of what large scale things can I

0:10:21.840 --> 0:10:24.560
<v Speaker 4>make out of the smallest visible pieces, you know, so

0:10:24.600 --> 0:10:26.240
<v Speaker 4>you're not really you know, I'm dealing with things in

0:10:26.280 --> 0:10:29.200
<v Speaker 4>an atomic level obviously, but especially as a child, like

0:10:29.960 --> 0:10:33.760
<v Speaker 4>the sand seems like the boundary of smallness, and it's like,

0:10:34.160 --> 0:10:36.160
<v Speaker 4>you bring these together, you make a clump, you make

0:10:36.200 --> 0:10:40.240
<v Speaker 4>a ball that becomes a tower. Towers are bridged together,

0:10:40.360 --> 0:10:43.680
<v Speaker 4>becomes a castle, and yeah, I think there's there's something

0:10:43.720 --> 0:10:46.360
<v Speaker 4>insightful there, Like we begin to sort of gaze into

0:10:46.400 --> 0:10:50.040
<v Speaker 4>these mysteries of sand at an early age. All right,

0:10:50.160 --> 0:10:53.760
<v Speaker 4>So for the majority of the section I'm taking in

0:10:53.800 --> 0:10:56.720
<v Speaker 4>this episode, I wanted to talk about a couple of

0:10:56.800 --> 0:11:02.040
<v Speaker 4>ideas from science fiction concerning sand. And these are little

0:11:02.920 --> 0:11:05.400
<v Speaker 4>ideas that are in neither in either neither case or

0:11:05.480 --> 0:11:07.640
<v Speaker 4>they particularly key to the work. You could take them

0:11:07.640 --> 0:11:09.880
<v Speaker 4>out of each work and it would it would be fine.

0:11:09.920 --> 0:11:12.080
<v Speaker 4>But they've always stuck in my mind because they were

0:11:12.160 --> 0:11:14.800
<v Speaker 4>neat uses of sand, and so I'm kind of using

0:11:14.840 --> 0:11:17.680
<v Speaker 4>those as a place to jump off to briefly talk

0:11:17.720 --> 0:11:21.760
<v Speaker 4>about some other mostly space related topics, but also some

0:11:23.040 --> 0:11:26.280
<v Speaker 4>kind of like military world and infrastructure type topics.

0:11:26.720 --> 0:11:28.119
<v Speaker 2>So the first before.

0:11:27.880 --> 0:11:29.480
<v Speaker 4>I get to Doon, the one I want to mention

0:11:29.920 --> 0:11:33.120
<v Speaker 4>is a nineteen eighty four novel that fewer people have read,

0:11:33.120 --> 0:11:34.440
<v Speaker 4>but it still has quite a following.

0:11:34.480 --> 0:11:35.240
<v Speaker 2>It's called Armor.

0:11:35.600 --> 0:11:38.800
<v Speaker 4>It's by an author by the name of John Stakley

0:11:39.880 --> 0:11:42.360
<v Speaker 4>st A. K. L. E. Y. If you're looking him up.

0:11:43.240 --> 0:11:46.760
<v Speaker 4>This is the same guy who wrote Vampires with a

0:11:46.880 --> 0:11:51.280
<v Speaker 4>Dollar Sign, which John Carpenter. Well, John Carpenter directed the

0:11:51.320 --> 0:11:56.480
<v Speaker 4>adaptation of it. As we've discussed before, probably not at

0:11:56.600 --> 0:11:58.960
<v Speaker 4>anybody like the top of anybody's Carpenter list.

0:11:59.360 --> 0:12:00.640
<v Speaker 2>Still has some great moments in it.

0:12:01.000 --> 0:12:02.679
<v Speaker 3>Uh, they're seeing the whole thing.

0:12:02.760 --> 0:12:03.520
<v Speaker 2>Actual, Oh you haven't.

0:12:04.040 --> 0:12:05.719
<v Speaker 3>I was not able to finish it at the time

0:12:05.760 --> 0:12:07.400
<v Speaker 3>I tried to watch it. I can't remember a huge

0:12:07.400 --> 0:12:10.040
<v Speaker 3>Carpenter fan, but I just didn't love this one.

0:12:10.200 --> 0:12:12.880
<v Speaker 2>It it has its moments, but the book, the book

0:12:12.920 --> 0:12:14.880
<v Speaker 2>was better in my memory.

0:12:15.480 --> 0:12:16.440
<v Speaker 3>Arm the Dollar Sign.

0:12:17.280 --> 0:12:20.800
<v Speaker 2>The dollar Sign was cool. Uh is it about money?

0:12:21.520 --> 0:12:21.800
<v Speaker 3>Yeah?

0:12:21.840 --> 0:12:24.280
<v Speaker 4>You know, the business of slaying vampires. I'm a little

0:12:24.320 --> 0:12:26.360
<v Speaker 4>foggy on that. The main thing that I that sticks

0:12:26.360 --> 0:12:28.160
<v Speaker 4>with me out of that book is just how scary

0:12:28.200 --> 0:12:31.440
<v Speaker 4>the vampires were, Like, they were just scary and nasty

0:12:32.679 --> 0:12:34.560
<v Speaker 4>in a way that they touched on a little bit

0:12:34.600 --> 0:12:36.920
<v Speaker 4>in the movie. But they're just really awful. You just

0:12:37.000 --> 0:12:41.360
<v Speaker 4>hate vampires in this book. Armor, however, is more in

0:12:41.440 --> 0:12:44.680
<v Speaker 4>keeping with like your Starship Troopers sort of world where

0:12:44.679 --> 0:12:49.520
<v Speaker 4>it's humans in power armor, like crazy powerful power armor,

0:12:49.720 --> 0:12:54.640
<v Speaker 4>and they're battling insect aliens on the surface of a

0:12:54.679 --> 0:12:59.600
<v Speaker 4>distant desert world called Bansheet. And there are a lot

0:12:59.600 --> 0:13:01.880
<v Speaker 4>of interests twist and turns in this, and the writing's

0:13:01.960 --> 0:13:04.880
<v Speaker 4>really bombastic, and you know, you really feel the action.

0:13:05.360 --> 0:13:08.480
<v Speaker 4>But at one point, the human faction here with their

0:13:08.520 --> 0:13:12.720
<v Speaker 4>power armored soldiers, they use a large high tech, you know,

0:13:12.760 --> 0:13:19.720
<v Speaker 4>sci fi machine and a sand clotter called a Siliconite eighteen,

0:13:20.280 --> 0:13:23.360
<v Speaker 4>and they use this this combination to suck sand in

0:13:23.480 --> 0:13:25.800
<v Speaker 4>through the front of this machine and then it like

0:13:25.920 --> 0:13:30.960
<v Speaker 4>leaves behind it essentially prints a trail of five meter tall,

0:13:31.080 --> 0:13:35.800
<v Speaker 4>perfectly smooth stone wall to fortify their makeshift base out

0:13:35.840 --> 0:13:36.880
<v Speaker 4>on this desert world.

0:13:37.120 --> 0:13:40.800
<v Speaker 3>Okay, so it sucks in sand and it adheres it

0:13:40.840 --> 0:13:42.119
<v Speaker 3>into a solid substance.

0:13:42.320 --> 0:13:42.520
<v Speaker 2>Yeah.

0:13:42.600 --> 0:13:47.080
<v Speaker 4>Yeah, it creates like a solid sand brick wall, which

0:13:47.160 --> 0:13:48.840
<v Speaker 4>I always thought was pretty cool. And I'm kind of

0:13:48.840 --> 0:13:53.160
<v Speaker 4>surprised I haven't seen that used in media elsewhere, in

0:13:53.240 --> 0:13:54.240
<v Speaker 4>video games or something.

0:13:54.280 --> 0:13:56.079
<v Speaker 2>Maybe it is, but.

0:13:56.960 --> 0:13:59.719
<v Speaker 4>This is this is really interesting because yes, we're talking

0:13:59.760 --> 0:14:04.040
<v Speaker 4>about sci fi far future warfare here, but of course

0:14:04.520 --> 0:14:07.320
<v Speaker 4>humans have been doing this in the real world for

0:14:07.400 --> 0:14:10.319
<v Speaker 4>quite a while, often in the form of sandbags.

0:14:10.559 --> 0:14:15.599
<v Speaker 3>Yeah, funny story. So this podcast started a lot of

0:14:15.600 --> 0:14:18.720
<v Speaker 3>people who listen probably don't even know this. This podcast

0:14:18.760 --> 0:14:23.040
<v Speaker 3>started originally when we were writers and editors for the

0:14:23.080 --> 0:14:27.160
<v Speaker 3>website HowStuffWorks dot com many many years ago, which was

0:14:27.200 --> 0:14:31.840
<v Speaker 3>like a encyclopedic informational website that had articles like, you know,

0:14:31.920 --> 0:14:34.280
<v Speaker 3>how a car engine works and stuff. So I was

0:14:34.360 --> 0:14:37.760
<v Speaker 3>hired on you were a writer at that website when

0:14:37.800 --> 0:14:40.240
<v Speaker 3>I joined as an editor and I don't know what

0:14:40.280 --> 0:14:41.360
<v Speaker 3>in twenty ten.

0:14:41.280 --> 0:14:43.720
<v Speaker 2>Or something, and then be four times.

0:14:43.840 --> 0:14:47.120
<v Speaker 3>Yeah, that long long ago, and one of the first

0:14:47.240 --> 0:14:52.440
<v Speaker 3>articles I edited for the website was how sand bags work. Now,

0:14:52.480 --> 0:14:54.640
<v Speaker 3>you wouldn't think that there's that much to say about

0:14:54.680 --> 0:14:56.760
<v Speaker 3>how a sandbag works, But I remember it being a

0:14:56.800 --> 0:15:00.680
<v Speaker 3>surprisingly rich and interesting topic. But all the things sandbags

0:15:00.680 --> 0:15:03.080
<v Speaker 3>can do and in fact to do better than other

0:15:03.160 --> 0:15:05.359
<v Speaker 3>more high tech solutions exactly.

0:15:05.480 --> 0:15:08.760
<v Speaker 4>Yeah, it's pretty fascinating. Like I grew up in a

0:15:08.800 --> 0:15:11.200
<v Speaker 4>household my dad was always into a lot of like

0:15:11.240 --> 0:15:14.200
<v Speaker 4>World War II stuff and did models of tanks, and

0:15:14.240 --> 0:15:16.840
<v Speaker 4>so I was familiar with pictures of tanks, and in

0:15:17.080 --> 0:15:18.920
<v Speaker 4>reading about sandbags here, I had to go back and

0:15:18.960 --> 0:15:21.680
<v Speaker 4>remind myself, Oh, yeah, they would off. You see all

0:15:21.720 --> 0:15:25.240
<v Speaker 4>these images of World War two tanks with sandbags layered

0:15:25.280 --> 0:15:28.160
<v Speaker 4>on top of the metal armor of the tank to

0:15:28.280 --> 0:15:33.800
<v Speaker 4>add like additional in the field protection against ballistics. So

0:15:33.880 --> 0:15:35.640
<v Speaker 4>I was reading a bit more about this out like

0:15:35.680 --> 0:15:39.520
<v Speaker 4>why are sandbags good for this twenty sixteen study from

0:15:39.600 --> 0:15:43.040
<v Speaker 4>chin at all from the National University of Singapore, and

0:15:43.040 --> 0:15:46.920
<v Speaker 4>this was published by ASM International, and they conducted a

0:15:47.000 --> 0:15:49.800
<v Speaker 4>study and in the study pointed out that, yeah, of

0:15:49.840 --> 0:15:52.520
<v Speaker 4>course sand has been used in fortifications for a long time,

0:15:52.600 --> 0:15:55.800
<v Speaker 4>and we've known that it's great at absorbing energy. But

0:15:55.840 --> 0:15:57.920
<v Speaker 4>they looked into it a little bit more and they

0:15:57.920 --> 0:16:01.640
<v Speaker 4>found that sand can absorb more than eighty five percent

0:16:01.720 --> 0:16:05.560
<v Speaker 4>of the energy exerted against it, and its resistance actually

0:16:05.600 --> 0:16:09.359
<v Speaker 4>increases with the speed of the projectile, even at high velocities.

0:16:09.720 --> 0:16:13.800
<v Speaker 4>So they experimented by firing various projectiles at silica sand blocks,

0:16:14.440 --> 0:16:16.600
<v Speaker 4>and one of the really interesting things they point out

0:16:16.640 --> 0:16:19.960
<v Speaker 4>is that when a projectile hits a block of compacted sand,

0:16:20.720 --> 0:16:23.440
<v Speaker 4>such as I believe like in a compacted military sand

0:16:23.600 --> 0:16:29.000
<v Speaker 4>bag or a hesco bastion, which is a collapsible wire

0:16:29.080 --> 0:16:32.600
<v Speaker 4>mesh container that then gets filled up with sand or

0:16:32.720 --> 0:16:37.200
<v Speaker 4>soil or gravel. But the extreme frictional force of the

0:16:37.240 --> 0:16:41.479
<v Speaker 4>sand particles against the projectile passing through it can potentially

0:16:41.520 --> 0:16:46.160
<v Speaker 4>break that projectile into pieces. So think to your childhood,

0:16:46.200 --> 0:16:49.560
<v Speaker 4>perhaps if you were a beach going child digging in

0:16:49.600 --> 0:16:53.400
<v Speaker 4>the sand and eventually feeling your hands becoming raw from

0:16:53.400 --> 0:16:56.400
<v Speaker 4>all those sand particles, you know, because it's sand. Now,

0:16:56.480 --> 0:17:00.720
<v Speaker 4>imagine a projectile passing through compacted sand and high speed

0:17:01.160 --> 0:17:05.040
<v Speaker 4>and the friction of that. It's pretty fascinating like that

0:17:05.080 --> 0:17:08.520
<v Speaker 4>this could essentially destroy the projectile as it passes through.

0:17:09.000 --> 0:17:10.679
<v Speaker 2>Meanwhile, the same.

0:17:10.440 --> 0:17:14.760
<v Speaker 4>Projectile, if it is powerful enough to pass through a

0:17:14.880 --> 0:17:17.880
<v Speaker 4>metal barrier, it will just pass through and can continue

0:17:17.880 --> 0:17:20.960
<v Speaker 4>to you know, decimate somebody or something on the other side.

0:17:22.320 --> 0:17:24.399
<v Speaker 4>So one of the things they end up arguing in

0:17:24.400 --> 0:17:27.320
<v Speaker 4>this paper is like we should be looking at more

0:17:27.359 --> 0:17:31.359
<v Speaker 4>ways to use sand, either in place of substances like

0:17:31.440 --> 0:17:35.199
<v Speaker 4>steel or figuring out how the best layer them with

0:17:35.359 --> 0:17:39.199
<v Speaker 4>steel or other materials. Like I guess it's it's just

0:17:39.240 --> 0:17:41.600
<v Speaker 4>fascinating to think. You know, we think about the armor

0:17:41.640 --> 0:17:44.800
<v Speaker 4>of the future. We think about things like power armor

0:17:44.880 --> 0:17:49.040
<v Speaker 4>and suits and steel and plate. Powerful plates are energy, yeah,

0:17:49.240 --> 0:17:52.560
<v Speaker 4>or plastic plastic steel, you know, some sort of crazy

0:17:52.560 --> 0:17:55.359
<v Speaker 4>plastic that's as strong as steel. But at the end

0:17:55.400 --> 0:17:57.080
<v Speaker 4>of the day, there's a strong case to be made

0:17:57.200 --> 0:18:00.280
<v Speaker 4>like that we should not forget sand, because sand again

0:18:00.400 --> 0:18:04.560
<v Speaker 4>is just an amazing you know, absorbent substance for these

0:18:04.600 --> 0:18:07.320
<v Speaker 4>sorts of projectiles and the sorts of this sort of energy.

0:18:07.440 --> 0:18:10.600
<v Speaker 3>Well, I know you were already talking about this. I

0:18:10.640 --> 0:18:12.880
<v Speaker 3>think maybe this came up when we were talking last night,

0:18:13.000 --> 0:18:16.120
<v Speaker 3>But you know, I recall seeing plenty of examples through

0:18:16.760 --> 0:18:20.440
<v Speaker 3>you know, world history, military history of like metal, plate,

0:18:20.560 --> 0:18:24.000
<v Speaker 3>armor and sand used in combination, like one one against

0:18:24.000 --> 0:18:24.360
<v Speaker 3>the other.

0:18:24.720 --> 0:18:27.000
<v Speaker 4>Yeah, yeah, I mean, you know, certainly you see a

0:18:27.040 --> 0:18:29.520
<v Speaker 4>lot of like makeshift you can pack up the sand

0:18:29.520 --> 0:18:31.160
<v Speaker 4>bags and you create a little wall. And then there's

0:18:31.200 --> 0:18:33.160
<v Speaker 4>the example of the tanks. But I don't know, there's

0:18:33.200 --> 0:18:36.399
<v Speaker 4>something about like I don't recall ever really putting it

0:18:36.440 --> 0:18:38.440
<v Speaker 4>together too much that oh yeah, I'm looking at sandbags

0:18:38.480 --> 0:18:41.800
<v Speaker 4>on those tanks. You know, it's one of those things

0:18:41.800 --> 0:18:44.879
<v Speaker 4>that's so mundane. You know, you see sand bags a lot,

0:18:46.040 --> 0:18:49.600
<v Speaker 4>you can kind of become blind to what's going on.

0:18:49.520 --> 0:18:52.280
<v Speaker 3>There, to the beauty of the sand bag.

0:18:52.480 --> 0:19:05.399
<v Speaker 4>Yeah yeah, all right, Now, moving from the sandbag back

0:19:05.640 --> 0:19:10.000
<v Speaker 4>into the science fiction future, let's come at last to done. Okay,

0:19:10.240 --> 0:19:12.880
<v Speaker 4>Frank Herbert's nineteen sixty five novel, and then the same

0:19:12.880 --> 0:19:14.840
<v Speaker 4>technology does come up a little bit at least in

0:19:14.880 --> 0:19:17.120
<v Speaker 4>one of the other books, but it does make it.

0:19:17.119 --> 0:19:19.240
<v Speaker 4>It does hit in the first one as well. So

0:19:19.280 --> 0:19:22.760
<v Speaker 4>the Friemen make use of a sand compactor as part

0:19:22.760 --> 0:19:25.000
<v Speaker 4>of the standard frim kit. You know, the frimekit is

0:19:25.040 --> 0:19:27.360
<v Speaker 4>the thing, like you know, it's hidden away for Paul

0:19:27.440 --> 0:19:29.240
<v Speaker 4>and his mother, and you know, then they have to

0:19:29.320 --> 0:19:32.000
<v Speaker 4>use it on their own surviving out in the sands

0:19:32.040 --> 0:19:32.719
<v Speaker 4>of Aracus.

0:19:32.760 --> 0:19:35.680
<v Speaker 3>So that's also going to have still suit yep, still suit.

0:19:35.760 --> 0:19:37.920
<v Speaker 3>It goes on your body, it protects you it keeps

0:19:37.920 --> 0:19:40.480
<v Speaker 3>you from losing moisture to the environment. Does it have

0:19:40.520 --> 0:19:45.000
<v Speaker 3>a thumper the thumper, yeah, around kit it either is

0:19:45.040 --> 0:19:48.160
<v Speaker 3>it either a tract or it distracts the worm? Yeah?

0:19:48.320 --> 0:19:48.760
<v Speaker 2>Yeah, both.

0:19:49.080 --> 0:19:51.480
<v Speaker 4>Yeah, there's a yeah, depending on how you're using it.

0:19:51.680 --> 0:19:53.960
<v Speaker 4>There's the tent, I believe, and then there are probably

0:19:54.000 --> 0:19:56.080
<v Speaker 4>some things that aren't mentioned. There's probably I'm thinking there's

0:19:56.080 --> 0:19:57.480
<v Speaker 4>a mint in there, maybe a piece of gum.

0:19:57.520 --> 0:19:58.320
<v Speaker 2>I don't know why not.

0:19:59.320 --> 0:20:03.880
<v Speaker 4>But the sand compact, Yeah, you want a little moisturizer,

0:20:03.960 --> 0:20:06.720
<v Speaker 4>you know, maybe a nice note. Oh there was a note,

0:20:06.760 --> 0:20:10.040
<v Speaker 4>but I don't know how nice it was. It's like, hey, sorry,

0:20:10.680 --> 0:20:15.160
<v Speaker 4>but I had to do this. But yeah, the sand

0:20:15.200 --> 0:20:18.080
<v Speaker 4>compactor is probably one of the weirder ones. And I

0:20:18.119 --> 0:20:20.480
<v Speaker 4>remember like thinking it was really cool when I first

0:20:20.560 --> 0:20:24.359
<v Speaker 4>read Dune, because it is described as a sand compaction

0:20:24.560 --> 0:20:28.359
<v Speaker 4>tool that realigns sand grains and allows you allows you

0:20:28.440 --> 0:20:32.240
<v Speaker 4>to effortlessly burrow out of a sand buried tint, and

0:20:32.480 --> 0:20:35.400
<v Speaker 4>presumably has other purposes. I think it's used slightly differently

0:20:35.520 --> 0:20:38.280
<v Speaker 4>in a later book, but I'm assuming you could also

0:20:38.359 --> 0:20:40.480
<v Speaker 4>use it to maybe blast the sand off of your feet,

0:20:41.280 --> 0:20:44.879
<v Speaker 4>And it seemingly involves binding sand grains together with an

0:20:44.920 --> 0:20:46.280
<v Speaker 4>electromagnetic charge.

0:20:46.440 --> 0:20:48.480
<v Speaker 2>Oh okay, yeah.

0:20:48.160 --> 0:20:51.600
<v Speaker 4>Now, as I understand it, the cool thing about this

0:20:51.720 --> 0:20:54.000
<v Speaker 4>is that this particular gadget, of course, remains a tool

0:20:54.040 --> 0:20:56.760
<v Speaker 4>of the far future imperium we see in dune, but

0:20:56.880 --> 0:21:01.320
<v Speaker 4>we do have electrostatic gadgets that can clean up sand.

0:21:01.960 --> 0:21:05.920
<v Speaker 4>There's something called an EDS electrodynamic screen, which is kind

0:21:05.960 --> 0:21:10.359
<v Speaker 4>of an electrostatic cleaning system for removal of sand particles

0:21:10.359 --> 0:21:13.160
<v Speaker 4>from solar panels. Because you know, you have a bunch

0:21:13.200 --> 0:21:16.359
<v Speaker 4>of sand accumulate, you know, even in just little bits

0:21:16.359 --> 0:21:18.080
<v Speaker 4>of it on solar panels, that's going to get in

0:21:18.080 --> 0:21:21.440
<v Speaker 4>the way of how effective they are. So this technology

0:21:21.560 --> 0:21:27.320
<v Speaker 4>exerts an electrostatic force to remove sand from that screen. Okay,

0:21:27.440 --> 0:21:29.960
<v Speaker 4>So in a sense, yeah, there's a connection to be

0:21:30.000 --> 0:21:33.240
<v Speaker 4>made between these two different technologies.

0:21:32.600 --> 0:21:34.280
<v Speaker 3>Like an electromagnetic vacuum.

0:21:34.840 --> 0:21:35.240
<v Speaker 2>Yeah.

0:21:35.320 --> 0:21:38.639
<v Speaker 4>Yeah, But again, this is the kind of thing I

0:21:38.640 --> 0:21:40.520
<v Speaker 4>feel like would make me more of a beach camper

0:21:40.560 --> 0:21:43.800
<v Speaker 4>if I could like point a flashlight sort of shaped

0:21:43.840 --> 0:21:45.879
<v Speaker 4>object at my feet and just kind of like hose

0:21:45.920 --> 0:21:51.760
<v Speaker 4>them off with pure dry electrostatic charge or something. Now,

0:21:52.320 --> 0:21:56.200
<v Speaker 4>coming back to the idea of sand constructions on other worlds,

0:21:56.240 --> 0:21:58.679
<v Speaker 4>So kind of coming back to that armor example of

0:21:58.920 --> 0:22:03.080
<v Speaker 4>printing out fortresses is on Banshee. There are actually a

0:22:03.160 --> 0:22:05.920
<v Speaker 4>number of proposals to do a certain amount of manipulation

0:22:06.560 --> 0:22:11.400
<v Speaker 4>of the regulith on our moon as well as on Mars.

0:22:13.160 --> 0:22:18.040
<v Speaker 4>The lunar regulith isn't quite sand by many definitions. It's

0:22:18.040 --> 0:22:20.639
<v Speaker 4>sometimes referred to as such, and sometimes it's called soil,

0:22:20.800 --> 0:22:23.159
<v Speaker 4>though plenty of people will point out, well, it's not soil.

0:22:23.600 --> 0:22:24.560
<v Speaker 2>Earth. Soil is of.

0:22:24.520 --> 0:22:28.920
<v Speaker 4>Course essentially a living, thriving, organically active thing, and that.

0:22:28.880 --> 0:22:30.120
<v Speaker 2>Is not what you get on the moon.

0:22:30.440 --> 0:22:32.840
<v Speaker 4>Yeah, we've gone into more depth than this sort of

0:22:32.880 --> 0:22:34.800
<v Speaker 4>thing before when we talked about like like what is

0:22:34.880 --> 0:22:38.240
<v Speaker 4>like lunar dust, and often dust is a is a

0:22:38.520 --> 0:22:42.440
<v Speaker 4>is good or a better descriptor as well. But there

0:22:42.480 --> 0:22:45.359
<v Speaker 4>is the idea that we could create various sort of

0:22:45.600 --> 0:22:51.280
<v Speaker 4>sometimes called lunar crets or astrocrets, that are essentially there

0:22:51.320 --> 0:22:53.959
<v Speaker 4>are a lot basically there are a lot like terrestrial concretes.

0:22:54.920 --> 0:22:57.600
<v Speaker 4>They would they would still be complicated to carry out.

0:22:57.880 --> 0:23:00.239
<v Speaker 4>Like it's not just a matter of like well them

0:23:00.320 --> 0:23:01.960
<v Speaker 4>up to the Moon or send them to Mars with

0:23:02.240 --> 0:23:06.119
<v Speaker 4>just a bag of mix that you buy at the store.

0:23:06.440 --> 0:23:09.760
<v Speaker 4>You're still dealing with something that would be difficult to

0:23:09.760 --> 0:23:13.760
<v Speaker 4>carry out, especially in such an environment. And you know,

0:23:13.840 --> 0:23:15.760
<v Speaker 4>essentially in some of these cases might have to be

0:23:15.800 --> 0:23:18.679
<v Speaker 4>like three D printed as well. But it's a It

0:23:18.720 --> 0:23:22.080
<v Speaker 4>means that you wouldn't have to bring everything as a

0:23:22.160 --> 0:23:25.520
<v Speaker 4>module up from Earth and then send it over. You

0:23:25.520 --> 0:23:29.520
<v Speaker 4>could create some amount of your infrastructure, you know, foundations,

0:23:29.920 --> 0:23:34.040
<v Speaker 4>you know, even whole buildings or tunnel systems by transforming

0:23:35.000 --> 0:23:37.199
<v Speaker 4>you know, the sand if you will, that you have

0:23:37.359 --> 0:23:43.480
<v Speaker 4>there into some sort of concrete, AstroCrete or lunar crete substance. Now,

0:23:43.640 --> 0:23:47.280
<v Speaker 4>this next example is fascinating because it also it makes

0:23:47.520 --> 0:23:51.240
<v Speaker 4>perfect sense once it's rolled out, but it also feels

0:23:51.320 --> 0:23:54.200
<v Speaker 4>like even more sci fi than some of these cases,

0:23:54.240 --> 0:23:58.080
<v Speaker 4>Like it sounds like a little more grim dark than

0:23:58.480 --> 0:24:01.879
<v Speaker 4>than anything that is actually rolled out in the book Armor,

0:24:02.920 --> 0:24:07.200
<v Speaker 4>but it's really cool. So AstroCrete, as proposed by scientists

0:24:07.240 --> 0:24:10.560
<v Speaker 4>from the University of Manchester, this calls for the use

0:24:10.600 --> 0:24:15.359
<v Speaker 4>of human urea and other excretions to strengthen the regalith concrete,

0:24:15.800 --> 0:24:20.479
<v Speaker 4>essentially making a kind of biocomposite out of it, and

0:24:20.680 --> 0:24:25.600
<v Speaker 4>is plenty of science has bricks PP bricks. But as

0:24:25.640 --> 0:24:28.200
<v Speaker 4>I think, one of the main things that the headlines

0:24:28.200 --> 0:24:34.000
<v Speaker 4>and even the authors of the proponents of this plan,

0:24:35.400 --> 0:24:37.760
<v Speaker 4>the way that they put it is blood, saying like

0:24:37.960 --> 0:24:41.960
<v Speaker 4>this would be like the blood of astronauts. So there's

0:24:41.960 --> 0:24:45.960
<v Speaker 4>a twenty twenty one study here published in Materials Today

0:24:45.960 --> 0:24:49.760
<v Speaker 4>Bio and the title is Blood, Sweat and Tears Extraterrestrial

0:24:49.960 --> 0:24:54.960
<v Speaker 4>regalith Biocomposits with in vivo Binders by Roberts at All

0:24:55.600 --> 0:24:59.399
<v Speaker 4>And yeah, they get into it and discuss how a

0:24:59.480 --> 0:25:02.679
<v Speaker 4>protein from human blood, the proteins from human blood can

0:25:02.720 --> 0:25:06.760
<v Speaker 4>form this biocomposite material with the moon, the Moon's dust

0:25:06.920 --> 0:25:10.440
<v Speaker 4>or the Mars dust, you know, the sand of either world,

0:25:10.520 --> 0:25:13.760
<v Speaker 4>if you will, And that the compressive strength of the

0:25:13.760 --> 0:25:18.880
<v Speaker 4>biocomposite materials is ultimately on par with concrete and by

0:25:18.920 --> 0:25:23.359
<v Speaker 4>incorporating incorporating urea from urine, they can actually increase the

0:25:23.480 --> 0:25:27.720
<v Speaker 4>compressive strength by over three hundred percent. So there's power

0:25:27.760 --> 0:25:32.440
<v Speaker 4>EMPP bricks, blood, MPP bricks, blood and MPP bricks. Yeah,

0:25:32.480 --> 0:25:35.040
<v Speaker 4>and this would be something that would be potentially then

0:25:35.080 --> 0:25:39.840
<v Speaker 4>three D printed on site, so something actually not unlike

0:25:39.960 --> 0:25:44.480
<v Speaker 4>the wall printers in the novel Armor at least in spirit.

0:25:45.560 --> 0:25:47.800
<v Speaker 4>And one thing that they do stress and this is,

0:25:48.160 --> 0:25:50.120
<v Speaker 4>you know, you get into the logistics of this, you'd

0:25:50.119 --> 0:25:58.280
<v Speaker 4>have to have your astronauts essentially continuously donating plasma, you know,

0:25:58.359 --> 0:26:00.440
<v Speaker 4>on top of their waste products, which are going to

0:26:00.480 --> 0:26:03.600
<v Speaker 4>have to shed anyway, but donating plasma for the purposes

0:26:04.080 --> 0:26:06.800
<v Speaker 4>of them later three D printing these bricks.

0:26:07.160 --> 0:26:08.840
<v Speaker 3>So I think that's they're not going to be under

0:26:08.840 --> 0:26:10.000
<v Speaker 3>any stress or anything.

0:26:10.320 --> 0:26:13.959
<v Speaker 4>Yeah, but the authors here do make a point of

0:26:14.000 --> 0:26:17.080
<v Speaker 4>saying you would need to figure out exactly what the

0:26:17.160 --> 0:26:21.080
<v Speaker 4>right regiment for this would be, you know, because I

0:26:21.280 --> 0:26:24.720
<v Speaker 4>guess on the way over, maybe they were to a

0:26:24.760 --> 0:26:27.960
<v Speaker 4>certain extent more be more downtalent downtime, and you could

0:26:28.000 --> 0:26:31.480
<v Speaker 4>kind of like put your astronauts on drip and get

0:26:31.480 --> 0:26:36.080
<v Speaker 4>some fluids from them. But we know that journeys between

0:26:37.000 --> 0:26:40.480
<v Speaker 4>planets and journeys between our world and its moon, these

0:26:40.480 --> 0:26:45.520
<v Speaker 4>are not stress free environments either, so you can't you

0:26:45.600 --> 0:26:48.040
<v Speaker 4>have to. Basically, their point is like you don't want

0:26:48.080 --> 0:26:52.359
<v Speaker 4>to in any way incapacitate or decrease the effectiveness of

0:26:52.400 --> 0:26:56.480
<v Speaker 4>your astronauts, while at the same time, you know, putting

0:26:56.480 --> 0:26:58.760
<v Speaker 4>them on drip a little bit in order to build

0:26:58.800 --> 0:26:59.920
<v Speaker 4>your bricks in the future.

0:27:00.080 --> 0:27:03.520
<v Speaker 2>Okay, yeah, so I don't know, I really really like

0:27:03.600 --> 0:27:04.000
<v Speaker 2>this idea.

0:27:04.000 --> 0:27:05.280
<v Speaker 4>It's been out for a few years, so I can

0:27:05.359 --> 0:27:08.879
<v Speaker 4>only imagine that somebody's latched onto it. In science fiction,

0:27:10.280 --> 0:27:15.040
<v Speaker 4>certainly some of the more recent Mars colony Lunar colony visions, well,

0:27:15.080 --> 0:27:15.320
<v Speaker 4>you know.

0:27:15.320 --> 0:27:18.679
<v Speaker 3>You could imagine that if if the stress on the

0:27:18.680 --> 0:27:22.400
<v Speaker 3>astronaut's body is too much, you could have a kind

0:27:22.400 --> 0:27:25.000
<v Speaker 3>of separate classes of people going to other planets. So

0:27:25.040 --> 0:27:27.480
<v Speaker 3>you'd have you'd have the astronauts who were there to work,

0:27:27.520 --> 0:27:28.919
<v Speaker 3>and then the ones who were there to be a

0:27:29.040 --> 0:27:31.560
<v Speaker 3>to be a blood and peepye bag. Oh you know.

0:27:32.280 --> 0:27:34.199
<v Speaker 2>Yeah, that that's interesting.

0:27:34.280 --> 0:27:36.240
<v Speaker 4>That certainly, that's the kind of idea you could explore

0:27:36.240 --> 0:27:38.240
<v Speaker 4>in some of these and some of them have talking

0:27:38.240 --> 0:27:42.080
<v Speaker 4>about different caste systems for far future humans on other worlds.

0:27:42.160 --> 0:27:43.880
<v Speaker 3>But a Mars blood boy.

0:27:43.880 --> 0:27:48.639
<v Speaker 4>Yeah, Mary, yeah, I ad read it all right. I

0:27:48.680 --> 0:27:52.679
<v Speaker 4>have one more one last spacesand topic I want to

0:27:52.680 --> 0:27:57.119
<v Speaker 4>discuss here, and it involves the electric sand of Titan,

0:27:58.160 --> 0:28:01.320
<v Speaker 4>which I have to admit, so it's pretty metal. It

0:28:01.520 --> 0:28:02.920
<v Speaker 4>is ultimately pretty metal.

0:28:03.960 --> 0:28:06.600
<v Speaker 3>So we've covered tight song by Sleep I think.

0:28:07.720 --> 0:28:11.400
<v Speaker 4>It could very much be a sleep song or an

0:28:11.400 --> 0:28:16.040
<v Speaker 4>early electric Wizard song from some of their spacier material. Yeah,

0:28:17.359 --> 0:28:20.639
<v Speaker 4>basically could fit just about any like seventies dim sound.

0:28:20.800 --> 0:28:22.840
<v Speaker 3>Drop out of Life on a rope of sand.

0:28:23.080 --> 0:28:26.480
<v Speaker 4>Yeah, yeah, that kind of vibe. Yeah, So we're going

0:28:26.480 --> 0:28:29.080
<v Speaker 4>to tighten for this topic. We've covered Titan on the

0:28:29.080 --> 0:28:32.639
<v Speaker 4>show before. This is Saturn's largest moon. It has a

0:28:32.720 --> 0:28:36.120
<v Speaker 4>thick atmosphere and earth like systems of flowing liquid only

0:28:36.160 --> 0:28:39.760
<v Speaker 4>instead of water. It has liquid hydrocarbons such as methane

0:28:39.800 --> 0:28:43.280
<v Speaker 4>and ethane. However, it may have a subsurface ocean of water,

0:28:43.440 --> 0:28:46.600
<v Speaker 4>and in many ways it is very earth like. But

0:28:47.520 --> 0:28:50.920
<v Speaker 4>with that caveat caveat of don't go anywhere beyond Earth

0:28:51.160 --> 0:28:55.440
<v Speaker 4>and expect to easily find something exactly like Earth. So

0:28:55.480 --> 0:28:58.680
<v Speaker 4>it's still very extreme. It's very cold, it has ice

0:28:58.800 --> 0:29:02.120
<v Speaker 4>like rocks and possible believe volcanoes that spout liquid water.

0:29:03.240 --> 0:29:06.000
<v Speaker 4>It's it's a rough place if we were to imagine

0:29:06.000 --> 0:29:09.680
<v Speaker 4>ourselves physically being there. It's the second largest moon in

0:29:09.720 --> 0:29:13.160
<v Speaker 4>our Solar system, trailing the Jovian moon of Ganymede. It's

0:29:13.280 --> 0:29:17.640
<v Speaker 4>larger than both Earth's moon and the planet mercury, and

0:29:18.120 --> 0:29:19.360
<v Speaker 4>it does have sand.

0:29:19.720 --> 0:29:21.520
<v Speaker 3>I think that comes with an asterisk though.

0:29:21.760 --> 0:29:21.960
<v Speaker 2>Yeah.

0:29:22.000 --> 0:29:24.680
<v Speaker 4>Yeah, anytime we're talking about sand in other worlds, we

0:29:25.520 --> 0:29:29.440
<v Speaker 4>have to add the caveat that we scientists will disagree

0:29:29.480 --> 0:29:32.640
<v Speaker 4>on terminology from time to time, but scientists will often

0:29:32.760 --> 0:29:35.320
<v Speaker 4>use the term sand when talking about it, at least,

0:29:35.360 --> 0:29:39.520
<v Speaker 4>you know, with the public. So, as described on the

0:29:39.640 --> 0:29:43.120
<v Speaker 4>NASA fact sheet for Titan, dark earth like sand dunes

0:29:43.160 --> 0:29:46.840
<v Speaker 4>stretch across the cross parts of Titan, and the sand

0:29:46.880 --> 0:29:51.520
<v Speaker 4>is composed of dark hydrocarbon grains, often described as probably

0:29:51.520 --> 0:29:55.480
<v Speaker 4>looking like coffee grounds. Interesting, So again, you know, it

0:29:55.480 --> 0:29:59.360
<v Speaker 4>feels very doom metal, you know, black deserts of weird sand.

0:30:00.720 --> 0:30:03.640
<v Speaker 4>And I included an image here in our notes, Joe,

0:30:03.880 --> 0:30:07.160
<v Speaker 4>maybe we can even splash this up for video to see,

0:30:07.160 --> 0:30:11.760
<v Speaker 4>since it's a NASA JPL image. But what I'm looking

0:30:11.800 --> 0:30:17.120
<v Speaker 4>at here is an image of sand dunes on the

0:30:17.160 --> 0:30:22.240
<v Speaker 4>moon of Titan. And this is detected via Cassini's radar.

0:30:23.200 --> 0:30:26.520
<v Speaker 3>So like just long, long, parallel dunes like you might

0:30:26.560 --> 0:30:29.160
<v Speaker 3>see in some deserts on Earth.

0:30:29.240 --> 0:30:29.880
<v Speaker 2>Yeah exactly.

0:30:29.920 --> 0:30:32.880
<v Speaker 4>So it's frequently compared to deserts on Earth and people

0:30:32.920 --> 0:30:36.240
<v Speaker 4>pointing out, yeah, yeah, this is kind of like an

0:30:36.320 --> 0:30:40.360
<v Speaker 4>Earth desert, except very different in other ways. But where

0:30:40.400 --> 0:30:43.120
<v Speaker 4>this gets really cool? I thought, I mean, it's already

0:30:43.120 --> 0:30:47.400
<v Speaker 4>really cool. But in twenty seventeen, Joshua Mendez, a granular

0:30:47.560 --> 0:30:52.440
<v Speaker 4>dynamicist at the Georgia Institute of Technology in Atlanta, proposed

0:30:52.440 --> 0:30:56.800
<v Speaker 4>in a paper published in Nature Geoscience titled Electrification of

0:30:56.880 --> 0:31:00.560
<v Speaker 4>Sand on Titan and its Influence on Sediment Transport that

0:31:00.600 --> 0:31:06.240
<v Speaker 4>the sands might become electrically charged via the tribal electric effect.

0:31:06.640 --> 0:31:09.480
<v Speaker 4>This is something we experience all the time, like say,

0:31:09.520 --> 0:31:12.440
<v Speaker 4>when you have static electricity that causes packing peanuts to

0:31:12.440 --> 0:31:16.320
<v Speaker 4>clean to your fingers. You know, the grains of sand

0:31:16.360 --> 0:31:19.800
<v Speaker 4>on Titan might do something similar in a very unique

0:31:19.840 --> 0:31:23.520
<v Speaker 4>way for a number of reasons. So the sand grains

0:31:23.560 --> 0:31:27.320
<v Speaker 4>on Titan there are fluffier than sand on Earth, and

0:31:27.360 --> 0:31:30.480
<v Speaker 4>the gravity there is seven times weaker than our own,

0:31:30.600 --> 0:31:33.920
<v Speaker 4>meaning that the sand particles can potentially stick together in

0:31:33.960 --> 0:31:36.479
<v Speaker 4>ways that we just do not see on Earth. So

0:31:36.520 --> 0:31:39.920
<v Speaker 4>we have the same you know, the trivial electric effect

0:31:40.080 --> 0:31:42.200
<v Speaker 4>is going to be in play here on Earth with sand,

0:31:42.200 --> 0:31:44.760
<v Speaker 4>but we have a different gravity situation and different consistency

0:31:44.760 --> 0:31:49.240
<v Speaker 4>of our sand grains. But The headline grabbing take home here,

0:31:49.720 --> 0:31:52.160
<v Speaker 4>as the researchers discuss, is that you could make a

0:31:52.200 --> 0:31:56.600
<v Speaker 4>sand castle on Titan out of this crazy goth black

0:31:56.680 --> 0:31:59.560
<v Speaker 4>sand and it might stay up for weeks without the

0:31:59.560 --> 0:32:02.280
<v Speaker 4>need of or anything to It would just be the

0:32:02.320 --> 0:32:04.600
<v Speaker 4>electric charge holding everything together.

0:32:05.040 --> 0:32:05.560
<v Speaker 3>Interesting.

0:32:05.680 --> 0:32:07.600
<v Speaker 2>Okay, so I'm imagining not.

0:32:07.640 --> 0:32:12.640
<v Speaker 4>Sand castle's, but like weird, like Wayne Barlow esque alien

0:32:13.000 --> 0:32:17.719
<v Speaker 4>sculptures on Titan out of this stuff. The deeper application

0:32:18.280 --> 0:32:22.160
<v Speaker 4>here is that, you know, beyond the flashy headlines, is

0:32:22.200 --> 0:32:24.800
<v Speaker 4>that it might explain the shape and formation of these

0:32:24.800 --> 0:32:28.200
<v Speaker 4>sand dunes we just explained that can't as easily be

0:32:28.280 --> 0:32:31.600
<v Speaker 4>accounted for by the wind. So, you know, we look

0:32:31.640 --> 0:32:33.959
<v Speaker 4>at the way sand dunes form on Earth and then

0:32:34.000 --> 0:32:35.800
<v Speaker 4>we look at this example on Titan. We're like, oh,

0:32:35.840 --> 0:32:37.880
<v Speaker 4>it's like we have here, except we're not going to

0:32:37.920 --> 0:32:40.360
<v Speaker 4>have the same wind scenario on Titan to form them.

0:32:40.720 --> 0:32:43.360
<v Speaker 4>This may be what's key to the formation of these

0:32:43.440 --> 0:32:44.560
<v Speaker 4>dunes on Titan.

0:32:44.880 --> 0:32:48.520
<v Speaker 3>That's really interesting. Yeah, reminds me of something we've talked

0:32:48.560 --> 0:32:51.480
<v Speaker 3>about on the surface of Jupiter's moon Io, where there

0:32:51.520 --> 0:32:56.400
<v Speaker 3>was a similar question about has shifting sand dunes sand

0:32:56.480 --> 0:32:58.800
<v Speaker 3>dunes that move over time and we can see that

0:32:58.920 --> 0:33:03.080
<v Speaker 3>through like orbit imagery, and so the question is how

0:33:03.120 --> 0:33:07.560
<v Speaker 3>do they move because Io basically has no appreciable atmosphere.

0:33:07.600 --> 0:33:09.959
<v Speaker 3>You know, it's not going to have winds like our

0:33:10.000 --> 0:33:14.280
<v Speaker 3>atmosphere does. And I remember the main hypothesis we looked

0:33:14.280 --> 0:33:16.560
<v Speaker 3>at for that was a paper that was talking about

0:33:16.600 --> 0:33:19.920
<v Speaker 3>sort of explosive gusts of gas that I think are

0:33:19.960 --> 0:33:25.440
<v Speaker 3>related to volcanic activity on Io, essentially creating temporary transient

0:33:25.600 --> 0:33:28.600
<v Speaker 3>winds even though though there's not really much of an atmosphere,

0:33:28.840 --> 0:33:30.640
<v Speaker 3>right right, Yeah.

0:33:30.280 --> 0:33:31.200
<v Speaker 2>Yeah, fascinating.

0:33:41.160 --> 0:33:43.520
<v Speaker 4>All right, we're going to move on to another section

0:33:43.720 --> 0:33:47.560
<v Speaker 4>here and this this is your angle. And I think

0:33:47.560 --> 0:33:49.680
<v Speaker 4>this is a great selection, in part because it gets

0:33:49.720 --> 0:33:52.760
<v Speaker 4>into some other like major things that come to our mind.

0:33:52.800 --> 0:33:55.400
<v Speaker 4>When we think about sand, things that sand can be

0:33:55.440 --> 0:33:59.120
<v Speaker 4>turned into. They go well beyond just making it into

0:33:59.160 --> 0:33:59.800
<v Speaker 4>a brick or a.

0:33:59.760 --> 0:34:00.440
<v Speaker 2>Bag of sand.

0:34:00.480 --> 0:34:02.800
<v Speaker 3>It's not just for sand bags. So yeah, we've talked

0:34:02.800 --> 0:34:06.080
<v Speaker 3>about sand in its loose form, and of course I

0:34:06.080 --> 0:34:11.040
<v Speaker 3>think everybody knows that melting sand is how you make glass,

0:34:11.520 --> 0:34:15.320
<v Speaker 3>but when it comes to making glass, not all sand

0:34:15.440 --> 0:34:18.520
<v Speaker 3>is the same. To make industrial glass with a high

0:34:18.600 --> 0:34:23.400
<v Speaker 3>level of transparency, modern glass makers usually select high purity

0:34:23.480 --> 0:34:28.319
<v Speaker 3>quartz sand, which consists of almost pure silicon dioxide or

0:34:28.320 --> 0:34:31.480
<v Speaker 3>silica and some other additives, usually to aid in the

0:34:31.480 --> 0:34:34.560
<v Speaker 3>manufacturing process, like they introduce stuff to lower the melting

0:34:34.600 --> 0:34:37.880
<v Speaker 3>point of the silica and make it easier to produce

0:34:38.520 --> 0:34:41.719
<v Speaker 3>or to produce desired characteristics in the final product. Is.

0:34:41.880 --> 0:34:46.320
<v Speaker 3>One example of this is introducing boron to the glass

0:34:46.520 --> 0:34:51.799
<v Speaker 3>boron trioxide to make what's called borosilicate glass. This kind

0:34:51.840 --> 0:34:55.040
<v Speaker 3>of glass has the benefit of being more resistant to

0:34:55.440 --> 0:34:59.440
<v Speaker 3>thermal shock due to a low coefficient of thermal expansion.

0:35:00.160 --> 0:35:02.760
<v Speaker 3>Rob And if you ever shattered something made of glass

0:35:02.840 --> 0:35:05.319
<v Speaker 3>due to heat mismanagement of heat and.

0:35:05.280 --> 0:35:08.760
<v Speaker 4>Cold, ooh maybe I haven't.

0:35:09.760 --> 0:35:10.440
<v Speaker 3>Well you're lucky.

0:35:10.480 --> 0:35:15.759
<v Speaker 4>Yeah, yeah, generally it's just the fingers to blame. Yeah, poor,

0:35:16.000 --> 0:35:19.200
<v Speaker 4>poor guesswork on how much of the table I have

0:35:19.280 --> 0:35:20.120
<v Speaker 4>set the glass on.

0:35:20.160 --> 0:35:21.680
<v Speaker 2>That sort of thing that can do it too.

0:35:21.719 --> 0:35:26.200
<v Speaker 3>But so, yeah, normal glass expands and contracts a lot,

0:35:27.040 --> 0:35:31.399
<v Speaker 3>relatively a lot. You know, it expands and contracts due

0:35:31.400 --> 0:35:34.960
<v Speaker 3>to changes in temperature. And so if you've got you know,

0:35:35.040 --> 0:35:38.000
<v Speaker 3>a glass or a glass baking you know, a glass container,

0:35:38.040 --> 0:35:41.960
<v Speaker 3>and you you change the temperatures on it too rapidly.

0:35:42.600 --> 0:35:45.960
<v Speaker 3>It creates stress on the brittle structure of the glass

0:35:45.960 --> 0:35:48.520
<v Speaker 3>because like in one part of it, it's getting hotter

0:35:48.680 --> 0:35:51.840
<v Speaker 3>faster than the other part and expanding faster or vice versa,

0:35:52.480 --> 0:35:55.680
<v Speaker 3>and this can cause it to shatter. Borosilicate glass is

0:35:55.719 --> 0:35:58.560
<v Speaker 3>better about this, which is why it is often used

0:35:58.600 --> 0:36:01.319
<v Speaker 3>to make glass bake where it's not. They do also

0:36:01.440 --> 0:36:06.600
<v Speaker 3>use sodaline glass to make glass bake bakeware, but borisilicate

0:36:06.600 --> 0:36:11.160
<v Speaker 3>glass is less vulnerable to thermal shocks, though not invulnerable.

0:36:11.200 --> 0:36:13.800
<v Speaker 3>I know people who have made baking you know, baking

0:36:13.840 --> 0:36:17.960
<v Speaker 3>dishes made of glass designed for that purpose still explode

0:36:18.200 --> 0:36:20.839
<v Speaker 3>due to mismanagement of hot and cold. You don't want

0:36:20.840 --> 0:36:24.080
<v Speaker 3>to like get a hot dish out of the oven,

0:36:24.200 --> 0:36:25.760
<v Speaker 3>you know, you've just had it in a four hundred

0:36:25.800 --> 0:36:27.840
<v Speaker 3>degree oven and then put it on like a puddle

0:36:27.880 --> 0:36:31.880
<v Speaker 3>of cold water or oh, kettle or something that'll that's dangerous.

0:36:31.880 --> 0:36:33.840
<v Speaker 4>Okay, that's that's good to know, because that is the

0:36:33.880 --> 0:36:36.959
<v Speaker 4>sort of thing I could conceivably do, and I will

0:36:37.000 --> 0:36:38.080
<v Speaker 4>I will make a point of not doing.

0:36:38.200 --> 0:36:40.160
<v Speaker 3>Don't don't do that. Yeah, that's how to make your

0:36:40.200 --> 0:36:44.799
<v Speaker 3>your baking dish explode anyway, that's industrial glass. But of

0:36:44.840 --> 0:36:48.200
<v Speaker 3>course there are also natural forms of glass made from

0:36:48.239 --> 0:36:50.720
<v Speaker 3>melted sand, and I want to talk about one type

0:36:50.719 --> 0:36:56.399
<v Speaker 3>of naturally occurring sand based glass called folgurite. So fulgurite

0:36:56.719 --> 0:37:01.560
<v Speaker 3>is a mineral made of silica or elicon dioxide that

0:37:01.680 --> 0:37:05.640
<v Speaker 3>has been fused by the heat of a bolt of lightning.

0:37:06.840 --> 0:37:09.480
<v Speaker 3>I thought that's pretty cool. So the name comes from

0:37:09.640 --> 0:37:12.440
<v Speaker 3>the Latin word for lightning, and it can be formed

0:37:12.440 --> 0:37:16.319
<v Speaker 3>when lightning hits multiple kinds of substrate. It can form

0:37:16.360 --> 0:37:19.560
<v Speaker 3>in clay or soil, or in solid rock, but the

0:37:19.560 --> 0:37:23.920
<v Speaker 3>most common type of folgarite is made when lightning strikes sand,

0:37:24.080 --> 0:37:28.239
<v Speaker 3>and for this reason you can often find folgiarites in beaches,

0:37:28.239 --> 0:37:32.800
<v Speaker 3>on beaches or in the desert. So a common recognizable

0:37:32.840 --> 0:37:38.040
<v Speaker 3>form of folgiarite is a partially buried, crusty looking tube.

0:37:38.200 --> 0:37:40.520
<v Speaker 3>But that's going to be hollow in the middle, and

0:37:40.560 --> 0:37:44.600
<v Speaker 3>then on the inner surface it will be glassy but

0:37:44.800 --> 0:37:48.440
<v Speaker 3>not usually smooth on the outside, so the outsides often

0:37:48.440 --> 0:37:51.360
<v Speaker 3>look very rough and gnobbily. And I was thinking they

0:37:51.440 --> 0:37:55.600
<v Speaker 3>look like a flute that orcs would play something of

0:37:55.960 --> 0:37:59.480
<v Speaker 3>mordor technology about them, or like that effect you get

0:37:59.520 --> 0:38:01.759
<v Speaker 3>when you earn a candle many times in a row,

0:38:01.840 --> 0:38:04.640
<v Speaker 3>and it creates this multi wax structure on the outside.

0:38:04.640 --> 0:38:06.840
<v Speaker 3>A lot of folgiarites look like that on the outside

0:38:07.320 --> 0:38:09.239
<v Speaker 3>due to I guess some kind of melting and then

0:38:09.880 --> 0:38:12.840
<v Speaker 3>partial melting around the outer surface, which is going to

0:38:12.920 --> 0:38:16.759
<v Speaker 3>mean that like unmelted sand, grains end up adhering to it,

0:38:16.920 --> 0:38:19.799
<v Speaker 3>so you get this rough outer surface. They vary in

0:38:19.840 --> 0:38:23.959
<v Speaker 3>thickness in length, somewhere between one and several centimeters thick,

0:38:24.480 --> 0:38:28.320
<v Speaker 3>and they sometimes have these branching or forked shapes, which

0:38:28.440 --> 0:38:31.759
<v Speaker 3>indicates the path the lightning took as it was conducted

0:38:31.840 --> 0:38:35.240
<v Speaker 3>into the ground through the soil or the rock. Around

0:38:35.280 --> 0:38:38.760
<v Speaker 3>the outside, again, they're usually covered with like rough sand

0:38:38.800 --> 0:38:42.880
<v Speaker 3>particles or pebbles. And the cool thing is that extremely

0:38:43.239 --> 0:38:47.080
<v Speaker 3>long fulgierites have been discovered, some sources say up to

0:38:47.160 --> 0:38:50.719
<v Speaker 3>twenty meters in length, though that doesn't necessarily mean you

0:38:50.760 --> 0:38:53.880
<v Speaker 3>can get it out intact, because as you can imagine,

0:38:54.400 --> 0:38:58.200
<v Speaker 3>it's like hard to extract a whole delicate glass tube

0:38:58.239 --> 0:38:59.920
<v Speaker 3>of that length from the ground intact.

0:39:00.480 --> 0:39:02.120
<v Speaker 4>Like I'm thinking, I mean, it's kind of like the

0:39:02.200 --> 0:39:05.239
<v Speaker 4>lightning has just cooked the sand, and so you could

0:39:05.280 --> 0:39:09.440
<v Speaker 4>imagine something like I don't know a cake that is,

0:39:09.480 --> 0:39:12.240
<v Speaker 4>the cake is on the whole not all that well cooked,

0:39:12.239 --> 0:39:15.000
<v Speaker 4>but you have like this thread going through it that

0:39:15.120 --> 0:39:16.439
<v Speaker 4>is really cooked.

0:39:16.320 --> 0:39:18.719
<v Speaker 3>Through thread going through the middle where part of the

0:39:18.719 --> 0:39:21.640
<v Speaker 3>cake has been vaporized and left as a hollow, and

0:39:21.680 --> 0:39:25.040
<v Speaker 3>then a section around that has been liquefied and then

0:39:25.120 --> 0:39:29.319
<v Speaker 3>re solidified, and this glassy, smooth inner channel, and then

0:39:29.480 --> 0:39:33.560
<v Speaker 3>a rougher surface around the outside. There are other types

0:39:33.600 --> 0:39:36.800
<v Speaker 3>of fulgarite, though it's not just sand. There are rock fulgarites.

0:39:36.920 --> 0:39:40.080
<v Speaker 3>These are a bit different. They usually appear as glassy

0:39:40.160 --> 0:39:44.120
<v Speaker 3>layers or glassy crusts on top of a rock, often

0:39:44.280 --> 0:39:46.719
<v Speaker 3>on mountain summits. So this is a really cool thing.

0:39:46.719 --> 0:39:48.200
<v Speaker 3>If you go to the top of a mountain, you

0:39:48.280 --> 0:39:51.880
<v Speaker 3>might find rocks near the very top have these little

0:39:51.880 --> 0:39:54.839
<v Speaker 3>places that are like a dark glassy patch on the rock.

0:39:54.920 --> 0:39:57.640
<v Speaker 3>What is that This is the place where the mountain

0:39:57.640 --> 0:40:01.160
<v Speaker 3>has formed a natural lightning rod is striking the rock

0:40:01.280 --> 0:40:04.160
<v Speaker 3>and melting it and turning it into this glassy surface.

0:40:05.360 --> 0:40:08.080
<v Speaker 3>Another thing is that when you see good examples of

0:40:08.120 --> 0:40:12.080
<v Speaker 3>these really forked or branching fulgiarites, sometimes they look like

0:40:12.120 --> 0:40:16.759
<v Speaker 3>a cross between a ginger root and ET's hand, but

0:40:16.880 --> 0:40:21.640
<v Speaker 3>more gray and crusty, usually also worth mentioning. Sometimes artificial

0:40:21.719 --> 0:40:26.080
<v Speaker 3>fulgarites can be formed by artificial injections of extreme heat

0:40:26.120 --> 0:40:29.760
<v Speaker 3>and energy into sand or rock, for example, by downed

0:40:29.800 --> 0:40:32.920
<v Speaker 3>power lines or by arc welders. You can make human

0:40:32.920 --> 0:40:37.279
<v Speaker 3>made folgiarites that way, and Charles Darwin actually talks at

0:40:37.360 --> 0:40:40.600
<v Speaker 3>length about fulgiarites in the Voyage of the Beagle. I

0:40:40.640 --> 0:40:43.880
<v Speaker 3>was trying to remember when I was making the notes

0:40:43.920 --> 0:40:47.120
<v Speaker 3>if this came up in our episode on ice Formations,

0:40:47.160 --> 0:40:50.160
<v Speaker 3>because in that one we were talking about Darwin's travels

0:40:50.200 --> 0:40:53.560
<v Speaker 3>in South America where he's going through a pass going

0:40:53.600 --> 0:40:57.520
<v Speaker 3>through what is today Chile and Argentina. But I don't

0:40:57.520 --> 0:41:00.200
<v Speaker 3>think this came up. You remember in that passage he

0:41:00.480 --> 0:41:03.600
<v Speaker 3>has these misadventures going through the very high mountain pass

0:41:03.640 --> 0:41:07.080
<v Speaker 3>where they tried he and his companions try to boil potatoes,

0:41:07.080 --> 0:41:08.320
<v Speaker 3>but the potatoes won't cook.

0:41:08.440 --> 0:41:10.040
<v Speaker 2>Oh yes, yes, they're at very.

0:41:10.000 --> 0:41:12.680
<v Speaker 3>High altitude, so the boiling point of water is lowered,

0:41:12.719 --> 0:41:15.319
<v Speaker 3>so the potatoes won't get hot enough moman boiling them.

0:41:16.080 --> 0:41:20.040
<v Speaker 3>But that's also the episode where he found the upside

0:41:20.080 --> 0:41:24.960
<v Speaker 3>down frozen horse in the Pinnacles of Ice yes, but anyway,

0:41:25.320 --> 0:41:28.520
<v Speaker 3>the part where he talks about finding Folgierites is in

0:41:28.640 --> 0:41:31.680
<v Speaker 3>chapter three of the Voyage of the Beagle called Maldonado,

0:41:31.800 --> 0:41:35.680
<v Speaker 3>where Darwin is traveling in what is I think modern

0:41:35.760 --> 0:41:39.120
<v Speaker 3>day Uruguay. But I'm just going to read from Darwin

0:41:39.160 --> 0:41:42.480
<v Speaker 3>here where he describes this find quote in a broad

0:41:42.600 --> 0:41:46.400
<v Speaker 3>band of sand hillocks which separate the Laguna de Potrero

0:41:46.600 --> 0:41:49.359
<v Speaker 3>from the shores of the Plata. At the distance of

0:41:49.440 --> 0:41:52.319
<v Speaker 3>a few miles from Maldonado, I found a group of

0:41:52.360 --> 0:41:57.640
<v Speaker 3>those vitrified silicious tubes which are formed by lightning entering

0:41:57.760 --> 0:42:01.640
<v Speaker 3>loose sand. These tubes resemble in every particular those from

0:42:01.800 --> 0:42:06.160
<v Speaker 3>drig In Cumberland described in the Geological Transactions. He's referring

0:42:06.200 --> 0:42:09.000
<v Speaker 3>to these other things that have been in the literature.

0:42:09.760 --> 0:42:13.480
<v Speaker 3>The sand hillocks of Maldonado, not being protected by vegetation,

0:42:14.080 --> 0:42:18.280
<v Speaker 3>are constantly changing their position. From this cause. The tubes

0:42:18.520 --> 0:42:24.080
<v Speaker 3>projected above the surface, and numerous fragments lying near showed

0:42:24.160 --> 0:42:27.160
<v Speaker 3>that they had formerly been buried to a greater depth.

0:42:27.600 --> 0:42:31.720
<v Speaker 3>Four sets entered the sand perpendicularly. By working with my hands,

0:42:31.760 --> 0:42:34.719
<v Speaker 3>I traced one of them two feet deep, and some

0:42:34.800 --> 0:42:38.000
<v Speaker 3>fragments which evidently had belonged to the same tube. When

0:42:38.040 --> 0:42:41.120
<v Speaker 3>added to the other part measured five feet three inches,

0:42:41.480 --> 0:42:44.239
<v Speaker 3>the diameter of the whole tube was nearly equal, and

0:42:44.280 --> 0:42:48.319
<v Speaker 3>therefore we must suppose that originally it extended to a

0:42:48.400 --> 0:42:52.560
<v Speaker 3>much greater depth. These dimensions are, however, small compared to

0:42:52.600 --> 0:42:55.759
<v Speaker 3>those of the tubes from drig one of which was

0:42:55.840 --> 0:42:58.919
<v Speaker 3>traced to a depth of not less than thirty feet. Again,

0:42:59.000 --> 0:43:03.480
<v Speaker 3>those incredibly deep. So after this he goes on describing

0:43:03.520 --> 0:43:06.799
<v Speaker 3>them a little bit more. He talks about how they're vitrified,

0:43:06.880 --> 0:43:09.759
<v Speaker 3>glossy and smooth on the inside, and then rough on

0:43:09.800 --> 0:43:14.480
<v Speaker 3>the outside. He compares the outside to a shriveled vegetable stalk,

0:43:14.640 --> 0:43:19.040
<v Speaker 3>or to the bark of an elm tree. And then

0:43:19.080 --> 0:43:21.440
<v Speaker 3>also he goes on to talk about some experiments that

0:43:21.520 --> 0:43:25.040
<v Speaker 3>have been conducted in Paris where they made artificial folgiarites

0:43:25.040 --> 0:43:29.000
<v Speaker 3>by passing a very strong shock of galvanism into a

0:43:29.040 --> 0:43:32.680
<v Speaker 3>finely powdered glass, and they managed to recreate some of

0:43:32.719 --> 0:43:37.120
<v Speaker 3>this effect. And let's see, there's one funny passage here.

0:43:37.840 --> 0:43:40.680
<v Speaker 3>He says, when we hear that the strongest battery in

0:43:40.760 --> 0:43:43.640
<v Speaker 3>Paris was used, and that its power on a substance

0:43:43.680 --> 0:43:46.880
<v Speaker 3>of such easy fusibility as glass was to form tubes

0:43:46.960 --> 0:43:50.560
<v Speaker 3>so diminutive, we must feel greatly astonished at the force

0:43:50.719 --> 0:43:53.440
<v Speaker 3>of a shock of lightning, which, striking the sand in

0:43:53.480 --> 0:43:56.759
<v Speaker 3>several places, has formed cylinders in one instance of at

0:43:56.840 --> 0:44:01.600
<v Speaker 3>least thirty feet long and having an internal when not compressed,

0:44:02.000 --> 0:44:04.880
<v Speaker 3>of full an inch and a half. And this in

0:44:04.920 --> 0:44:08.520
<v Speaker 3>a material so extraordinarily refractory as quartz.

0:44:09.080 --> 0:44:09.480
<v Speaker 2>Wow.

0:44:09.960 --> 0:44:13.120
<v Speaker 3>So Darwin was not confused about what these things were.

0:44:13.160 --> 0:44:16.360
<v Speaker 3>He already knew what they are, that they're made by lightning.

0:44:16.400 --> 0:44:18.960
<v Speaker 3>But I'm trying to imagine how interesting it would be

0:44:19.040 --> 0:44:22.160
<v Speaker 3>to go out like he did and find these in

0:44:22.239 --> 0:44:25.120
<v Speaker 3>the wild, protruding, like you said, in an area without

0:44:25.200 --> 0:44:28.640
<v Speaker 3>much vegetation, and these sand hillocks where you're going out,

0:44:28.680 --> 0:44:33.480
<v Speaker 3>and because the sand shifts and moves, these glass formations

0:44:33.520 --> 0:44:36.160
<v Speaker 3>are now sticking up into the air, exposed, and you

0:44:36.239 --> 0:44:38.319
<v Speaker 3>look at them, I'd imagine and say, like, what is

0:44:38.320 --> 0:44:40.800
<v Speaker 3>is that some kind of stalk or cactus or something,

0:44:40.840 --> 0:44:43.760
<v Speaker 3>and then you come upon it and realize it is glass?

0:44:44.040 --> 0:44:44.400
<v Speaker 1>Wow?

0:44:44.600 --> 0:44:48.600
<v Speaker 4>Yeah, just like alien formations growing up out of the sand.

0:44:48.719 --> 0:44:48.959
<v Speaker 2>Yeah.

0:44:49.239 --> 0:44:52.879
<v Speaker 3>Yeah, And I guess they eventually get broken off by

0:44:52.880 --> 0:44:55.279
<v Speaker 3>the weather, but sometimes they're just just having a good

0:44:55.320 --> 0:44:56.080
<v Speaker 3>old poke up there.

0:44:56.239 --> 0:44:56.560
<v Speaker 2>Wow.

0:44:57.760 --> 0:45:00.440
<v Speaker 3>So I wanted to also mention one scientific paper I

0:45:00.480 --> 0:45:02.920
<v Speaker 3>came across because the authors of this paper did an

0:45:02.960 --> 0:45:06.960
<v Speaker 3>interesting bit of calculation in their background section to estimate

0:45:07.040 --> 0:45:10.359
<v Speaker 3>the rate of Fulgiar right formation on Earth. So this

0:45:10.480 --> 0:45:13.920
<v Speaker 3>was a paper called a Fossilized Energy Distribution of Lightning.

0:45:14.000 --> 0:45:17.040
<v Speaker 3>This is by Matthew Passick and Mark Hurst, published in

0:45:17.080 --> 0:45:20.600
<v Speaker 3>Scientific Reports in twenty sixteen. I looked up the author

0:45:20.680 --> 0:45:23.319
<v Speaker 3>is Matthew Passick is a geochemist who was at the

0:45:23.360 --> 0:45:27.000
<v Speaker 3>time affiliated with the University of South Florida, and mark

0:45:27.040 --> 0:45:30.920
<v Speaker 3>Hurst is an independent geologist. But the authors of this

0:45:30.960 --> 0:45:33.920
<v Speaker 3>paper just start off by talking about how powerful lightning is,

0:45:33.960 --> 0:45:36.440
<v Speaker 3>and of course you know Darwin makes the same observation.

0:45:36.520 --> 0:45:39.360
<v Speaker 3>He's looking at this fused glass and then saying like

0:45:39.400 --> 0:45:42.719
<v Speaker 3>the most powerful battery in Paris could barely do you

0:45:42.760 --> 0:45:45.840
<v Speaker 3>know anything close to this, or imagine how powerful lightning

0:45:45.920 --> 0:45:50.640
<v Speaker 3>is to fuse all the sand in this way. The

0:45:50.680 --> 0:45:54.400
<v Speaker 3>authors here talk about the total energy of a lightning

0:45:54.440 --> 0:45:57.120
<v Speaker 3>strike might be up to ten to the nine jewels,

0:45:57.520 --> 0:46:00.520
<v Speaker 3>and that lightning can heat the air around it to

0:46:00.560 --> 0:46:05.200
<v Speaker 3>a temperature above thirty thousand kelvin. And of course, you know,

0:46:05.280 --> 0:46:09.800
<v Speaker 3>we think of lightning and its vast discharge of energy

0:46:09.880 --> 0:46:13.520
<v Speaker 3>as primarily destructive. When you imagine what lightning can do,

0:46:13.600 --> 0:46:15.640
<v Speaker 3>we think about things that it can hurt. You've got

0:46:15.680 --> 0:46:18.960
<v Speaker 3>your standard bolt of vengeance from Jupiter. You know, it

0:46:19.000 --> 0:46:21.400
<v Speaker 3>strikes a person dead, and then you know, the ancient

0:46:21.480 --> 0:46:23.920
<v Speaker 3>Romans might look at that in awe and like build

0:46:23.920 --> 0:46:27.320
<v Speaker 3>a shrine around that area, as a Jupiter has interacted

0:46:27.320 --> 0:46:29.000
<v Speaker 3>with this place, best not mess with it.

0:46:29.239 --> 0:46:31.200
<v Speaker 4>Yeah, I mean, when we think of putting it to use,

0:46:31.239 --> 0:46:34.360
<v Speaker 4>it's generally going to be bringing of Frankenstein's monster to

0:46:34.440 --> 0:46:37.239
<v Speaker 4>life or powering a time traveling glorean, and that that's

0:46:37.239 --> 0:46:39.680
<v Speaker 4>pretty much it. Those are the only applications.

0:46:39.160 --> 0:46:40.720
<v Speaker 2>Bold of lightning. Yeah.

0:46:40.760 --> 0:46:42.680
<v Speaker 3>But yeah, so it can do that. We know also

0:46:42.719 --> 0:46:47.040
<v Speaker 3>it can start fires, natural forest fires, and it causes

0:46:47.080 --> 0:46:50.759
<v Speaker 3>destruction and damage to buildings. But the authors here just

0:46:50.880 --> 0:46:53.960
<v Speaker 3>mentioned briefly a couple of things people might not appreciate

0:46:54.000 --> 0:46:58.200
<v Speaker 3>about how lightning is also somewhat ecologically important, like it

0:46:58.239 --> 0:47:01.360
<v Speaker 3>does good things for us. This is a detour, but

0:47:01.400 --> 0:47:03.040
<v Speaker 3>I thought it was interesting, so I just wanted to

0:47:03.080 --> 0:47:05.960
<v Speaker 3>mention it. One thing that has come up on the

0:47:05.960 --> 0:47:09.520
<v Speaker 3>show before, of course, is the ecological importance of lightning

0:47:09.719 --> 0:47:13.080
<v Speaker 3>in starting forest fires. Like some amount of forest fires

0:47:13.160 --> 0:47:17.960
<v Speaker 3>are necessary, right like, there are life forms that depend

0:47:18.120 --> 0:47:22.680
<v Speaker 3>on occasional or periodic forest fires. There are plant seeds

0:47:22.680 --> 0:47:25.600
<v Speaker 3>that are only activated in the presence of fire or smoke,

0:47:26.280 --> 0:47:29.160
<v Speaker 3>so you know, the life cycle of forests to some

0:47:29.280 --> 0:47:34.320
<v Speaker 3>degree depends on occasional forest fires. But also the authors

0:47:34.600 --> 0:47:36.520
<v Speaker 3>here bring up something that I don't think i'd ever

0:47:36.560 --> 0:47:40.239
<v Speaker 3>read about before, that lightning plays a small role in

0:47:40.440 --> 0:47:46.040
<v Speaker 3>nitrogen fixation on Earth, which nitrogen fixation is a process

0:47:46.040 --> 0:47:49.160
<v Speaker 3>that we absolutely depend on for life. You know, nitrogen

0:47:49.280 --> 0:47:53.239
<v Speaker 3>is a key component of amino acids and proteins. Without it,

0:47:53.239 --> 0:47:56.000
<v Speaker 3>we could not make DNA or RNA or the proteins

0:47:56.040 --> 0:47:59.160
<v Speaker 3>that build our cells. Plants couldn't make chlorophyll. So all

0:47:59.239 --> 0:48:02.800
<v Speaker 3>life on Earth pins on nitrogen. And you might think, well,

0:48:02.920 --> 0:48:05.280
<v Speaker 3>that's fine, because there's plenty of nitrogen in the atmosphere,

0:48:05.320 --> 0:48:08.719
<v Speaker 3>right like, nitrogen is the main constituent of our atmosphere,

0:48:09.040 --> 0:48:12.560
<v Speaker 3>But the form of nitrogen available in our atmosphere is

0:48:12.560 --> 0:48:17.799
<v Speaker 3>actually not biologically usable. Atmospheric nitrogen exists mostly in the

0:48:17.840 --> 0:48:22.680
<v Speaker 3>form of two nitrogen atoms bonded together called di nitrogen,

0:48:23.320 --> 0:48:26.360
<v Speaker 3>and these two atoms are held together by an extremely

0:48:26.400 --> 0:48:29.640
<v Speaker 3>strong chemical bond, so in order to be usable to life,

0:48:30.400 --> 0:48:33.279
<v Speaker 3>you have to break that bond. Dihydrogen needs to be

0:48:33.320 --> 0:48:36.640
<v Speaker 3>broken apart and converted into other compounds like nitrates which

0:48:36.640 --> 0:48:41.520
<v Speaker 3>are nitrogen oxygen compounds, or converted into ammonia, which is

0:48:41.520 --> 0:48:45.120
<v Speaker 3>made of nitrogen and hydrogen. So what can break apart

0:48:45.160 --> 0:48:50.520
<v Speaker 3>the di nitrogen the two nitrogen atoms. The vast majority

0:48:50.560 --> 0:48:55.320
<v Speaker 3>of the world's natural nitrogen fixation is done by microorganisms,

0:48:55.360 --> 0:48:58.640
<v Speaker 3>so you have single celled life forms like bacteria and

0:48:58.800 --> 0:49:04.360
<v Speaker 3>archaea called diazotrophs, which have special enzymes called nitrogenases that

0:49:04.400 --> 0:49:08.440
<v Speaker 3>are able to break the dinitrogen bonds and generate derivative compounds.

0:49:09.040 --> 0:49:11.840
<v Speaker 3>So one example of this is Rhizobia, which is a

0:49:11.880 --> 0:49:16.200
<v Speaker 3>type of bacteria that exists symbiotically in legume roots like

0:49:16.239 --> 0:49:19.520
<v Speaker 3>the roots of bean plants, and together with the plant,

0:49:19.600 --> 0:49:22.520
<v Speaker 3>the bacterium and the plant are able to convert atmospheric

0:49:22.600 --> 0:49:26.360
<v Speaker 3>nitrogen into ammonia or in H three. So most natural

0:49:26.440 --> 0:49:30.080
<v Speaker 3>nitrogen fixation happens like that, but some small amount of

0:49:30.120 --> 0:49:33.640
<v Speaker 3>the world's nitrogen fixation is also done by lightning. So

0:49:34.080 --> 0:49:38.360
<v Speaker 3>lightning is hot enough to break apart dinitrogen in the

0:49:38.400 --> 0:49:41.480
<v Speaker 3>atmosphere as it cuts a path to the ground, so

0:49:41.560 --> 0:49:45.719
<v Speaker 3>it breaks apart the dinitrogen and makes it react with

0:49:45.960 --> 0:49:50.520
<v Speaker 3>oxygen other elements in the atmosphere, primarily oxygen, and then

0:49:50.800 --> 0:49:54.200
<v Speaker 3>these nitrogen oxygen compounds are carried down to the ground

0:49:54.239 --> 0:49:56.480
<v Speaker 3>by rain and then they can be absorbed and used

0:49:56.480 --> 0:49:59.360
<v Speaker 3>by plants in the form of nitrate. So lightning helps.

0:50:00.160 --> 0:50:01.799
<v Speaker 4>Yeah, something to keep in mind the next time we

0:50:01.840 --> 0:50:05.640
<v Speaker 4>see some electrical activity in the storms, like we're looking

0:50:05.680 --> 0:50:08.640
<v Speaker 4>at a factory of sorts.

0:50:08.840 --> 0:50:09.120
<v Speaker 2>Yeah.

0:50:09.200 --> 0:50:13.560
<v Speaker 3>Yeah. So anyway, coming to the part about fulgurites, the

0:50:13.600 --> 0:50:17.560
<v Speaker 3>authors do some interesting mass to calculate how often folgiarites

0:50:17.680 --> 0:50:20.960
<v Speaker 3>around the world might be formed, and they I just

0:50:21.040 --> 0:50:23.239
<v Speaker 3>want to read this section. They say, quote, lightning is

0:50:23.280 --> 0:50:26.480
<v Speaker 3>a ubiquitous phenomenon on Earth, with a global flash rate

0:50:26.520 --> 0:50:30.360
<v Speaker 3>of about forty five times per second, a majority seventy

0:50:30.360 --> 0:50:33.960
<v Speaker 3>five to ninety percent of which occur over continental land mass.

0:50:34.280 --> 0:50:37.000
<v Speaker 3>About a quarter of these strikes occur from a cloud

0:50:37.080 --> 0:50:40.680
<v Speaker 3>to the ground, and hence the number of potential fulgiarit

0:50:40.800 --> 0:50:44.800
<v Speaker 3>forming events is significant. With up to ten folgarites formed

0:50:44.840 --> 0:50:46.200
<v Speaker 3>globally per second.

0:50:46.360 --> 0:50:46.840
<v Speaker 2>WHOA.

0:50:46.880 --> 0:50:50.600
<v Speaker 3>This estimate depends on the efficiency of fulgarite formation by lightning,

0:50:50.840 --> 0:50:54.520
<v Speaker 3>which is highest when striking barren sand, soil or rock.

0:50:54.640 --> 0:50:56.920
<v Speaker 3>So obviously there's going to be less formation when it's

0:50:56.920 --> 0:50:58.800
<v Speaker 3>striking like a forested area.

0:51:00.080 --> 0:51:03.000
<v Speaker 4>Still that is significantly more than I would have guessed.

0:51:03.120 --> 0:51:05.799
<v Speaker 3>Yeah. Now, one last thing I wanted to mention about

0:51:05.800 --> 0:51:09.040
<v Speaker 3>folgier ites is actually not about folgiar rights in sand.

0:51:09.160 --> 0:51:11.920
<v Speaker 3>This is about rock fulgiarites. But I thought this was

0:51:11.960 --> 0:51:14.120
<v Speaker 3>interesting too, so I wanted to get into it. Robin

0:51:14.160 --> 0:51:15.960
<v Speaker 3>the outline. I've got a picture you can look at

0:51:16.480 --> 0:51:20.319
<v Speaker 3>of the peak of Mount Shasta in California, and you

0:51:20.360 --> 0:51:23.400
<v Speaker 3>can see these dark scars in the rock. What's going

0:51:23.440 --> 0:51:27.280
<v Speaker 3>on there? That's rock fulgiarites. The mountain is a lightning

0:51:27.400 --> 0:51:29.560
<v Speaker 3>rod and the peak is being going to be struck

0:51:29.600 --> 0:51:33.040
<v Speaker 3>by lightning and it makes these glassy crusts in the rock.

0:51:33.280 --> 0:51:33.799
<v Speaker 2>Wow. Yeah.

0:51:33.880 --> 0:51:35.920
<v Speaker 4>To the untrained eye, you might just think it's like

0:51:36.000 --> 0:51:39.319
<v Speaker 4>deposits of something some sort of like mineral vein in

0:51:39.360 --> 0:51:39.759
<v Speaker 4>the rock.

0:51:39.800 --> 0:51:43.160
<v Speaker 2>But wow, that's fulgrit. Wow.

0:51:51.640 --> 0:51:53.359
<v Speaker 3>So the last thing I want to talk about here

0:51:53.440 --> 0:51:56.600
<v Speaker 3>is This news article in the journal Science from December

0:51:56.640 --> 0:52:00.680
<v Speaker 3>twenty twenty by Nick Ogassa called fossilized lightning to reveal

0:52:00.840 --> 0:52:06.280
<v Speaker 3>when ancient storms struck. So, when lightning strikes a mountaintop

0:52:06.360 --> 0:52:08.560
<v Speaker 3>like this, like when it hits the peak of Mount Shasta,

0:52:08.680 --> 0:52:11.680
<v Speaker 3>it leaves this glassy residue, And you can think of

0:52:11.719 --> 0:52:14.920
<v Speaker 3>this in a way as fossilized lightning. It is a

0:52:15.080 --> 0:52:18.840
<v Speaker 3>record in the rock of lightning hitting. So in a

0:52:18.880 --> 0:52:22.719
<v Speaker 3>way it is a record of weather projected into the

0:52:22.840 --> 0:52:25.879
<v Speaker 3>rock or into the soil and the sand. And these

0:52:25.920 --> 0:52:31.640
<v Speaker 3>fossilized signatures of thunderbolts can play an interesting role helping

0:52:31.680 --> 0:52:36.560
<v Speaker 3>scientists understand past climate patterns by allowing them to date thunderstorms.

0:52:36.719 --> 0:52:40.120
<v Speaker 3>So how does that work well? The article explains, citing

0:52:40.200 --> 0:52:43.360
<v Speaker 3>the work of Jonathan Castro, who's a volcanologist at the

0:52:43.719 --> 0:52:49.880
<v Speaker 3>Johannes Gutenberg University of Mines, that when naturally formed glasses

0:52:49.880 --> 0:52:54.040
<v Speaker 3>like fulgiarite and others like obsidian are exposed to the

0:52:54.080 --> 0:52:56.719
<v Speaker 3>outside air and to the elements, they slowly begin to

0:52:56.880 --> 0:53:02.360
<v Speaker 3>absorb water. And by measuring the amount of water they've absorbed,

0:53:02.400 --> 0:53:05.680
<v Speaker 3>and I think how deeply it's been absorbed in theory,

0:53:05.719 --> 0:53:08.439
<v Speaker 3>you should be able to measure the age of these

0:53:08.480 --> 0:53:11.879
<v Speaker 3>glasses because they absorbed slowly, and so you can measure that,

0:53:12.840 --> 0:53:15.120
<v Speaker 3>or at least you can measure not necessarily the age

0:53:15.160 --> 0:53:17.799
<v Speaker 3>since they're formed, but the age since they've been exposed

0:53:17.800 --> 0:53:21.480
<v Speaker 3>to the elements. So, for example, this has been considered

0:53:21.480 --> 0:53:25.080
<v Speaker 3>as a method for dating artifacts like obsidian arrowheads. But

0:53:25.280 --> 0:53:27.840
<v Speaker 3>there's a problem. They figured out there are problems with

0:53:27.880 --> 0:53:31.399
<v Speaker 3>the method because quote, many of these glasses come from

0:53:31.600 --> 0:53:36.240
<v Speaker 3>volcanoes and already contain water from the time they were forged,

0:53:37.480 --> 0:53:41.880
<v Speaker 3>so that water interferes with this potential dating method. But

0:53:42.160 --> 0:53:47.200
<v Speaker 3>Castro and colleagues reasoned that, unlike volcanically forged obsidian, fulgurites

0:53:47.239 --> 0:53:50.560
<v Speaker 3>could be free of this problem because the extremely high

0:53:50.680 --> 0:53:54.440
<v Speaker 3>energy of the lightning strike that creates the folgarite actually

0:53:54.600 --> 0:53:57.799
<v Speaker 3>vaporizes any water that's hiding out in there because it's

0:53:57.840 --> 0:54:02.200
<v Speaker 3>so hot, So fulurite last might be a more reliable

0:54:02.239 --> 0:54:06.560
<v Speaker 3>target for this moisture absorption based dating method. So Castro

0:54:06.680 --> 0:54:11.040
<v Speaker 3>and colleagues tested this out by making artificial rock fulgurite

0:54:11.520 --> 0:54:14.399
<v Speaker 3>by shocking samples of rock with an arc welder. Again,

0:54:14.440 --> 0:54:17.480
<v Speaker 3>these artificial things, like when you have a down to

0:54:17.520 --> 0:54:20.080
<v Speaker 3>power line and it makes folgiurite in the sand. They

0:54:20.160 --> 0:54:24.000
<v Speaker 3>shocked rock with an arc welder, reaching temperatures above ten

0:54:24.000 --> 0:54:28.200
<v Speaker 3>thousand degrees celsius, which is what's required to make the folgiarite,

0:54:28.760 --> 0:54:31.920
<v Speaker 3>and these temperatures did indeed boil away almost all of

0:54:31.920 --> 0:54:34.680
<v Speaker 3>the moisture, meaning that the fulgarite should serve as a

0:54:34.719 --> 0:54:37.759
<v Speaker 3>reliable time piece allowing you to measure the time since

0:54:37.760 --> 0:54:41.960
<v Speaker 3>its creation. And after this, the researchers decided to test

0:54:42.000 --> 0:54:46.000
<v Speaker 3>the dating system on natural rock fulgurites, which they harvested

0:54:46.000 --> 0:54:48.920
<v Speaker 3>from some volcanic mountain peaks in Oregon in the US

0:54:48.960 --> 0:54:52.360
<v Speaker 3>state of Oregon, because again mountain peaks are these lightning rods.

0:54:52.880 --> 0:54:55.880
<v Speaker 3>And some of the folgiarites they sampled turned out to

0:54:55.880 --> 0:54:58.480
<v Speaker 3>be hundreds of years old, and they argued that this

0:54:58.560 --> 0:55:01.759
<v Speaker 3>method could be used to date fulgarite glass with a

0:55:01.840 --> 0:55:05.600
<v Speaker 3>relatively high level of accuracy compared to other methods. Other

0:55:05.640 --> 0:55:09.360
<v Speaker 3>methods you might have like measuring bombardment by cosmic rays.

0:55:10.480 --> 0:55:13.120
<v Speaker 3>So in a paper published in twenty twenty in the

0:55:13.200 --> 0:55:16.800
<v Speaker 3>journal Earth and Planetary Science Letters, Castro and co authors

0:55:16.840 --> 0:55:21.359
<v Speaker 3>wrote that quote because the lightning strike is in and

0:55:21.440 --> 0:55:26.239
<v Speaker 3>of itself so effective at devolatilizing melts in an instant.

0:55:26.560 --> 0:55:29.840
<v Speaker 3>The resultant folgiarites are a unique earth material that record

0:55:30.000 --> 0:55:34.560
<v Speaker 3>individual weather events i e. A thunderstorm and also longer

0:55:34.640 --> 0:55:39.480
<v Speaker 3>term paleo weather intervals. And they talk about one interesting

0:55:39.520 --> 0:55:42.160
<v Speaker 3>example of how this could be used. It could reveal

0:55:42.280 --> 0:55:48.359
<v Speaker 3>when in history particular rocks or mountaintops became exposed and

0:55:48.400 --> 0:55:52.480
<v Speaker 3>thus vulnerable to lightning strikes, for example, to identify wind

0:55:52.600 --> 0:55:56.000
<v Speaker 3>glaciers began to retreat from specific areas with a high

0:55:56.040 --> 0:55:56.920
<v Speaker 3>degree of precision.

0:55:57.480 --> 0:55:59.560
<v Speaker 2>Fascinating. Yeah, huh.

0:56:00.120 --> 0:56:03.200
<v Speaker 3>I'm not a crystal guy. And if you start googling

0:56:03.239 --> 0:56:04.880
<v Speaker 3>Fulgar rightes, a lot of the people who want to

0:56:04.920 --> 0:56:08.800
<v Speaker 3>talk about these things have thoughts about the powers of crystals.

0:56:08.920 --> 0:56:12.120
<v Speaker 4>Oh, okay, there are certain powers attributed to Folgar rights

0:56:12.200 --> 0:56:13.160
<v Speaker 4>in particular.

0:56:12.920 --> 0:56:14.560
<v Speaker 3>I think some people I don't know. I didn't go

0:56:14.600 --> 0:56:16.160
<v Speaker 3>deep in that world. I just saw a bunch of

0:56:16.160 --> 0:56:18.120
<v Speaker 3>Google hits and I'm like, Okay, I don't have time

0:56:18.160 --> 0:56:18.400
<v Speaker 3>for that.

0:56:18.560 --> 0:56:21.840
<v Speaker 4>I'll research it the next time I'm in Asheville going

0:56:21.840 --> 0:56:23.160
<v Speaker 4>to the various crystal stores.

0:56:23.280 --> 0:56:26.239
<v Speaker 3>Yeah, so I'm not that kind of crystal guy. But

0:56:26.280 --> 0:56:29.520
<v Speaker 3>now I'm kind of like I want some vulgarite very

0:56:29.560 --> 0:56:30.880
<v Speaker 3>interested in this it.

0:56:31.239 --> 0:56:33.560
<v Speaker 4>You know, I didn't get a chance to reread Armor

0:56:33.920 --> 0:56:37.040
<v Speaker 4>in full for this episode. It's just like zeroing in

0:56:37.080 --> 0:56:40.600
<v Speaker 4>on the part that I referenced earlier. But this makes

0:56:40.640 --> 0:56:44.000
<v Speaker 4>me wonder if there's an example in that book, maybe

0:56:44.040 --> 0:56:47.000
<v Speaker 4>examples even in Dune, or certainly any book where you

0:56:47.120 --> 0:56:50.480
<v Speaker 4>have any fictional setting where you have an interaction of

0:56:50.520 --> 0:56:56.520
<v Speaker 4>some sort of energy weapon or dragon breath or Godzilla breath,

0:56:56.880 --> 0:57:00.400
<v Speaker 4>where you could potentially have like fulgar right scar of

0:57:00.400 --> 0:57:03.480
<v Speaker 4>the battle, you know, like I'm imagining like there was

0:57:03.480 --> 0:57:06.120
<v Speaker 4>some sort of interaction here, we had last guns, you know,

0:57:06.200 --> 0:57:08.640
<v Speaker 4>going off, or some sort of energy weapons, and then

0:57:08.719 --> 0:57:12.320
<v Speaker 4>later it could almost leave like a forest of fulgar

0:57:12.360 --> 0:57:15.720
<v Speaker 4>rite columns from where those like those missed laser beams

0:57:15.800 --> 0:57:18.120
<v Speaker 4>or what have you, impacted the sand and then the

0:57:18.120 --> 0:57:19.400
<v Speaker 4>rest of the sand blew away.

0:57:20.040 --> 0:57:23.920
<v Speaker 3>There are whole passages in Doing Messiah where Paul is

0:57:23.960 --> 0:57:27.200
<v Speaker 3>like looking out over the planes where Fremen fought the

0:57:27.200 --> 0:57:31.120
<v Speaker 3>Sarto car and he talks about the landscape and even

0:57:31.160 --> 0:57:33.720
<v Speaker 3>the rocks and the scarps and all that. But I

0:57:33.720 --> 0:57:35.480
<v Speaker 3>don't think he ever mentions anything like that.

0:57:35.520 --> 0:57:37.600
<v Speaker 4>I mean, it would be temporary, you know, because the

0:57:38.480 --> 0:57:43.080
<v Speaker 4>elements would be we was over. Yeah, and you know,

0:57:43.400 --> 0:57:45.320
<v Speaker 4>you can also imagine a scenario where things like this

0:57:45.400 --> 0:57:49.440
<v Speaker 4>might be collected because they're essentially you know, the mentos

0:57:49.600 --> 0:57:52.440
<v Speaker 4>of the battle, that sort of thing. But it's one

0:57:52.440 --> 0:57:53.640
<v Speaker 4>of those things I kind of want to look out

0:57:53.640 --> 0:57:57.480
<v Speaker 4>for now, and certainly listeners if you were like, oh, yeah,

0:57:57.560 --> 0:57:59.640
<v Speaker 4>there's a you know place in Game of Thrones where

0:57:59.720 --> 0:58:02.480
<v Speaker 4>this is reference towards reference. Again, it might actually be

0:58:02.520 --> 0:58:05.800
<v Speaker 4>referenced elsewhere in Herbert's Riding or in any of the

0:58:06.000 --> 0:58:09.320
<v Speaker 4>sources we've mentioned already, But it seems like there's some

0:58:09.320 --> 0:58:13.520
<v Speaker 4>some great potential there for fulgar ride battle scars.

0:58:13.600 --> 0:58:16.120
<v Speaker 3>I like it, are there energy weapons in Game of Thrones?

0:58:16.280 --> 0:58:19.720
<v Speaker 2>Well, you have dragons, Oh okay, I'm thinking of breath

0:58:19.760 --> 0:58:21.280
<v Speaker 2>weapon or.

0:58:22.920 --> 0:58:25.280
<v Speaker 4>You know, some sort of magical effects or or you know,

0:58:26.120 --> 0:58:30.520
<v Speaker 4>you know, other like high potency explosives. I don't know,

0:58:30.880 --> 0:58:33.000
<v Speaker 4>but certainly dragon fire it seems like that might be

0:58:33.000 --> 0:58:36.040
<v Speaker 4>the kind of thing that could produce fulgar rides in

0:58:36.080 --> 0:58:36.640
<v Speaker 4>some cases.

0:58:36.680 --> 0:58:37.120
<v Speaker 2>I don't know.

0:58:37.640 --> 0:58:41.600
<v Speaker 3>In D and D what level of electricity spells like

0:58:41.720 --> 0:58:43.920
<v Speaker 3>lightning or thunderbolt spells you have to get to to

0:58:43.960 --> 0:58:44.800
<v Speaker 3>make fulgar ride.

0:58:45.040 --> 0:58:47.400
<v Speaker 4>I think it would happen right away. I mean, just

0:58:47.480 --> 0:58:49.680
<v Speaker 4>your as soon as you're able to forget off the

0:58:49.720 --> 0:58:51.200
<v Speaker 4>top of my head, I don't have make character sheet

0:58:51.200 --> 0:58:51.640
<v Speaker 4>in front of me.

0:58:51.920 --> 0:58:52.440
<v Speaker 2>I can't remember.

0:58:52.640 --> 0:58:54.760
<v Speaker 4>You know, you get the lightning bolt spell and then

0:58:54.760 --> 0:58:58.080
<v Speaker 4>you can like really ramp it up depending on what

0:58:58.080 --> 0:59:00.880
<v Speaker 4>what spell over you're casting at. But right out the gate,

0:59:00.880 --> 0:59:02.880
<v Speaker 4>it's pretty strong spell, especially if you can get your

0:59:02.960 --> 0:59:03.920
<v Speaker 4>enemies to line up.

0:59:04.280 --> 0:59:05.360
<v Speaker 2>That's my favorite part.

0:59:05.200 --> 0:59:06.120
<v Speaker 3>Get them wet right.

0:59:06.400 --> 0:59:08.120
<v Speaker 4>Yeah, but sometimes that's where you have to like make

0:59:08.160 --> 0:59:09.800
<v Speaker 4>a case for it with your dungeon master. But if

0:59:09.840 --> 0:59:13.240
<v Speaker 4>your dungeon master makes a mistake of lining up all

0:59:13.280 --> 0:59:15.560
<v Speaker 4>of the villains, all of the bad guys, all the

0:59:15.560 --> 0:59:17.840
<v Speaker 4>monsters in us in a row, and you're able to

0:59:17.880 --> 0:59:21.440
<v Speaker 4>move your your player to the side of them, you're

0:59:21.440 --> 0:59:23.280
<v Speaker 4>able to flank them, then you can just like shoot

0:59:23.280 --> 0:59:26.520
<v Speaker 4>that lightning bolt straight down the middle. And if they're

0:59:27.080 --> 0:59:30.040
<v Speaker 4>you know, made up of land, you create fulgar rides.

0:59:30.160 --> 0:59:31.880
<v Speaker 3>Oh yeah based enemies.

0:59:31.920 --> 0:59:34.680
<v Speaker 4>Oh yeah, yeah, there's some sand based creatures. Yeah, for sure.

0:59:35.880 --> 0:59:38.920
<v Speaker 3>There's some sort of lightning spells on like a rock elemental.

0:59:39.080 --> 0:59:42.160
<v Speaker 4>Yeah, have some sort of sand golm that sort of thing. Yeah,

0:59:42.320 --> 0:59:44.000
<v Speaker 4>then you have a fulgar ride golum and that's a

0:59:44.040 --> 0:59:45.400
<v Speaker 4>whole new thing you have to contend with.

0:59:46.960 --> 0:59:48.440
<v Speaker 3>Okay, does that do it for today?

0:59:49.040 --> 0:59:50.360
<v Speaker 2>I think so. Yeah.

0:59:50.400 --> 0:59:52.800
<v Speaker 4>This has been a blast. You know, this is not

0:59:52.880 --> 0:59:56.200
<v Speaker 4>our normal recording scenario, but I had a lot of

0:59:56.200 --> 0:59:59.479
<v Speaker 4>fun doing it. Thanks to the studio here at Baja Mar,
