WEBVTT - The Tech of 1510

0:00:00.320 --> 0:00:02.960
<v Speaker 1>Brought to you by the reinvented two thousand twelve Cammeray.

0:00:03.200 --> 0:00:08.920
<v Speaker 1>It's ready. Are you get in touch with technology? With

0:00:09.080 --> 0:00:18.080
<v Speaker 1>tech Stuff from how stuff works dot com. Greetings, programs,

0:00:18.520 --> 0:00:20.759
<v Speaker 1>Welcome to tech stuff. My name is Chris Pellette, and

0:00:20.760 --> 0:00:22.680
<v Speaker 1>I am an editor here at how stuff works dot com.

0:00:22.680 --> 0:00:25.320
<v Speaker 1>Sitting across from me as always a senior writer Jonathan

0:00:25.360 --> 0:00:29.360
<v Speaker 1>Strickland Hale and well met Vedge and tools. Oh well,

0:00:29.360 --> 0:00:32.480
<v Speaker 1>now that's a completely different era. Yeah, well that's where

0:00:32.479 --> 0:00:35.360
<v Speaker 1>we're kind of going. We're gonna start this off with

0:00:35.400 --> 0:00:43.879
<v Speaker 1>a little listener mail. This listener mail comes from Annette,

0:00:43.880 --> 0:00:48.800
<v Speaker 1>and a net says dear John and Chris, but especially John. Hello,

0:00:48.840 --> 0:00:50.720
<v Speaker 1>my name is Annette, and I'm a listener of Josh

0:00:50.720 --> 0:00:54.480
<v Speaker 1>and Chuck's podcast. She left that bit out. I suggested

0:00:54.520 --> 0:00:57.240
<v Speaker 1>that they do a podcast about the Renaissance fair phenomenon

0:00:57.360 --> 0:01:00.840
<v Speaker 1>and creative anachronism. They referred me to you because you're

0:01:00.840 --> 0:01:04.520
<v Speaker 1>going to star in a Renaissance Fair. I understand that

0:01:04.560 --> 0:01:07.240
<v Speaker 1>this is not a typical tech stuff topic, but Josh

0:01:07.280 --> 0:01:09.959
<v Speaker 1>seems certain that you can work it in somehow. What

0:01:10.000 --> 0:01:12.680
<v Speaker 1>do you think by the way they say you guys

0:01:12.680 --> 0:01:17.800
<v Speaker 1>smell their words not mine best, Annett. Of course, I

0:01:17.800 --> 0:01:21.000
<v Speaker 1>think we've we've already fired back with the you smell

0:01:21.520 --> 0:01:25.760
<v Speaker 1>uh volley that that went up a couple of weeks ago. Yeah. Frankly,

0:01:25.920 --> 0:01:28.959
<v Speaker 1>I'm not sure how we evolved into you smell, No,

0:01:29.200 --> 0:01:31.120
<v Speaker 1>you smell, but I don't want to get into that.

0:01:31.200 --> 0:01:35.200
<v Speaker 1>They started it, they started it well, Annette, thank you

0:01:35.280 --> 0:01:38.120
<v Speaker 1>very much for the email, and yes it is true. Uh,

0:01:38.280 --> 0:01:43.000
<v Speaker 1>I am in a local Renaissance festival. Um, just so

0:01:43.160 --> 0:01:46.440
<v Speaker 1>you know, my character's name is Lord Admiral Edmund Vane

0:01:46.440 --> 0:01:50.240
<v Speaker 1>Glory the third as not a joke. And we're gonna

0:01:50.320 --> 0:01:58.600
<v Speaker 1>talk today about the tech of fifteen ten years ago.

0:01:58.720 --> 0:02:00.480
<v Speaker 1>Does that mean we need to get in the machine.

0:02:01.080 --> 0:02:03.520
<v Speaker 1>Let's not do that because it would be an entire

0:02:03.600 --> 0:02:06.640
<v Speaker 1>episode in the past and I think Liz would kill us.

0:02:08.120 --> 0:02:11.280
<v Speaker 1>But we are talking about the the technology of fifteen tens,

0:02:11.360 --> 0:02:15.760
<v Speaker 1>so let's set the stage a bit. Fifteen ten. King

0:02:15.840 --> 0:02:18.360
<v Speaker 1>Henry the Eighth has been on the throne for a

0:02:18.400 --> 0:02:24.880
<v Speaker 1>full year. Really he should never mind, No, not King

0:02:24.960 --> 0:02:30.080
<v Speaker 1>Henry the Eighth has ruled England for a full year. Uh. Yeah,

0:02:30.120 --> 0:02:32.640
<v Speaker 1>he he was coordinated in fifteen o nine, got married

0:02:32.680 --> 0:02:37.040
<v Speaker 1>to uh to Cat his first wife, Cat. We're really close.

0:02:37.639 --> 0:02:40.079
<v Speaker 1>Actually no we're not, because he was divorced by the time.

0:02:40.120 --> 0:02:45.200
<v Speaker 1>Well anyway, so fifteen o nine, fifteen ten, sorry, fifteen ten.

0:02:46.440 --> 0:02:49.520
<v Speaker 1>We're what kind of technology was around at this time?

0:02:49.600 --> 0:02:54.239
<v Speaker 1>And can we really call it technology? One of the uh,

0:02:54.560 --> 0:02:57.320
<v Speaker 1>of course we could call it technology. I mean lots

0:02:57.320 --> 0:02:59.360
<v Speaker 1>of things are technology, they just don't seem like it

0:02:59.400 --> 0:03:01.160
<v Speaker 1>now that we live in an age where there are

0:03:01.160 --> 0:03:03.920
<v Speaker 1>lots of circuits and things that beep. I thought that

0:03:03.960 --> 0:03:05.680
<v Speaker 1>was an important point to make, and I'm glad you

0:03:05.720 --> 0:03:09.480
<v Speaker 1>made it. Um Yeah, because I mean, thinking back to

0:03:09.520 --> 0:03:14.800
<v Speaker 1>our what's better paper or digital podcasts? I was thinking, well,

0:03:14.840 --> 0:03:17.000
<v Speaker 1>you know, paper is a technology. Before they had that,

0:03:17.040 --> 0:03:22.080
<v Speaker 1>we really didn't have some kind of portable, lightweight method

0:03:22.080 --> 0:03:24.960
<v Speaker 1>by which information could be preserved like that. I mean,

0:03:25.240 --> 0:03:30.680
<v Speaker 1>tables were not lightweight, nor were they particularly uh strong.

0:03:30.760 --> 0:03:35.520
<v Speaker 1>They didn't last forever, you know pretty yeah, yes, stone

0:03:35.640 --> 0:03:38.280
<v Speaker 1>is pretty sturdy. Well, not the easiest thing to write on.

0:03:38.560 --> 0:03:40.920
<v Speaker 1>Just just in making my point, I'll make this short.

0:03:41.160 --> 0:03:43.520
<v Speaker 1>Thinking about things like data rot in where you have

0:03:44.280 --> 0:03:47.600
<v Speaker 1>a DVD or a CD that lasts fifty years or

0:03:47.640 --> 0:03:49.640
<v Speaker 1>something like that. A piece of paper with ink on

0:03:49.680 --> 0:03:51.760
<v Speaker 1>that if you protect it can last longer than that.

0:03:51.920 --> 0:03:55.119
<v Speaker 1>So these are I'm just saying, okay, so very good.

0:03:55.200 --> 0:03:58.080
<v Speaker 1>The tricky part I found in researching this is all

0:03:58.120 --> 0:04:01.960
<v Speaker 1>the stuff that was invented in fifteen ten. I really

0:04:02.000 --> 0:04:04.200
<v Speaker 1>it's kind of hard to find anything that was specifically

0:04:04.200 --> 0:04:06.880
<v Speaker 1>invented in fifteen ten, but that lost lots of technology

0:04:06.920 --> 0:04:09.360
<v Speaker 1>actually had been going on before that, because they in

0:04:09.400 --> 0:04:12.640
<v Speaker 1>Europe we were going through the Renaissance right right now

0:04:12.680 --> 0:04:15.520
<v Speaker 1>in England. Parts in England you would probably call this

0:04:15.640 --> 0:04:18.680
<v Speaker 1>the High Middle Ages because really you get into the

0:04:18.680 --> 0:04:21.440
<v Speaker 1>Elizabethan era, that's when you start talking about the Renaissance

0:04:21.480 --> 0:04:23.800
<v Speaker 1>in England. But yes, other parts of the world were

0:04:24.560 --> 0:04:27.120
<v Speaker 1>far more advanced than England at this point. In fact,

0:04:27.120 --> 0:04:29.960
<v Speaker 1>if you look at places like China or or the

0:04:29.960 --> 0:04:33.600
<v Speaker 1>Middle East, they had made advances in technology that put

0:04:34.240 --> 0:04:38.000
<v Speaker 1>medieval Europe to shame. Um So, but we'll get into

0:04:38.080 --> 0:04:40.160
<v Speaker 1>some of that. Let's talk a little bit about some

0:04:40.200 --> 0:04:42.520
<v Speaker 1>of the things that you might have seen had you

0:04:42.560 --> 0:04:45.720
<v Speaker 1>been walking around medieval Europe in fifteen ten, the kind

0:04:45.760 --> 0:04:50.520
<v Speaker 1>of technologies you might encounter. All Right, So if you

0:04:50.600 --> 0:04:55.120
<v Speaker 1>were a sailor and you were in England in fifteen ten,

0:04:55.279 --> 0:04:57.400
<v Speaker 1>and you were one of the King's favorites, you might

0:04:57.440 --> 0:05:00.479
<v Speaker 1>get a chance to serve aboard the fla bag ship

0:05:00.640 --> 0:05:03.800
<v Speaker 1>of what was the brand new Royal Navy of England,

0:05:04.279 --> 0:05:08.159
<v Speaker 1>the flagship being called the Mary Rose. Yes Mary m

0:05:08.200 --> 0:05:11.440
<v Speaker 1>A r y not m E r r y uh

0:05:11.600 --> 0:05:15.039
<v Speaker 1>named as far as we know, after Henry the eighth

0:05:15.200 --> 0:05:20.480
<v Speaker 1>sister then, and the Mary Rose was a fairly new

0:05:20.600 --> 0:05:24.599
<v Speaker 1>kind of vessel um in England at the time it was.

0:05:24.880 --> 0:05:28.480
<v Speaker 1>It was had a carvel hull. Carvel hall, by the way,

0:05:28.680 --> 0:05:31.279
<v Speaker 1>does not mean it was Fudgi the whale or cookie pus.

0:05:32.880 --> 0:05:35.760
<v Speaker 1>It's not that kind of carvel Yeah, now I'm all

0:05:35.800 --> 0:05:39.760
<v Speaker 1>hungry a lot. Sorry. Um No, The carvel hall was

0:05:40.040 --> 0:05:43.919
<v Speaker 1>a specific way of building a ship previous to carvel

0:05:44.040 --> 0:05:48.760
<v Speaker 1>hall or the the the clinker ships. A clinker ship

0:05:49.000 --> 0:05:54.320
<v Speaker 1>was a made by making overland overlapping planks and then

0:05:54.360 --> 0:05:57.240
<v Speaker 1>you had a little frame that you could attach to that.

0:05:57.960 --> 0:06:01.400
<v Speaker 1>So the planks were the most important part. But the

0:06:01.480 --> 0:06:05.159
<v Speaker 1>carvel hull was used a strong framework and then used

0:06:05.560 --> 0:06:10.400
<v Speaker 1>planks that fit against each other, um in a more

0:06:10.480 --> 0:06:14.440
<v Speaker 1>or less a seamless fashion. Um. They weren't really possible

0:06:14.520 --> 0:06:17.960
<v Speaker 1>until you invented the saw. So it turns out the

0:06:18.000 --> 0:06:20.560
<v Speaker 1>saw was very important as far as the development of

0:06:20.720 --> 0:06:26.200
<v Speaker 1>naval warfare is concerned. High technology. Yeah, So you would

0:06:26.200 --> 0:06:28.400
<v Speaker 1>put these planks next to each other, you would calk them.

0:06:28.440 --> 0:06:31.000
<v Speaker 1>So that's water tight. Also very important as it turns out,

0:06:31.000 --> 0:06:36.760
<v Speaker 1>for boats, and it provided the opportunity to introduce watertight

0:06:36.839 --> 0:06:40.039
<v Speaker 1>gun poarts also very important. So the gun ports. That

0:06:40.040 --> 0:06:44.520
<v Speaker 1>allows you to put the guns closer to the the waterline,

0:06:45.279 --> 0:06:47.120
<v Speaker 1>you know, and you could close the gun ports and

0:06:47.160 --> 0:06:49.400
<v Speaker 1>you uh they were since they were watertight, you didn't

0:06:49.440 --> 0:06:51.640
<v Speaker 1>have to worry about water coming into the ship and

0:06:51.640 --> 0:06:55.440
<v Speaker 1>having a capsize. And uh that was that was actually

0:06:55.440 --> 0:06:57.599
<v Speaker 1>really important in that if you wanted to carry a

0:06:57.600 --> 0:07:00.280
<v Speaker 1>lot of guns on your ship, you couldn't just them

0:07:00.279 --> 0:07:03.119
<v Speaker 1>all on the deck. If you did, then that would

0:07:03.120 --> 0:07:05.360
<v Speaker 1>make the deck, it would make the ship top heavy,

0:07:05.600 --> 0:07:08.599
<v Speaker 1>so whenever you would turn, you would have the the

0:07:08.600 --> 0:07:12.200
<v Speaker 1>the danger of capsizing. This actually happened. There was a

0:07:13.240 --> 0:07:17.000
<v Speaker 1>a ship that was built about fifty or sixty years

0:07:17.000 --> 0:07:21.200
<v Speaker 1>before the time we're talking about, where it was the

0:07:21.200 --> 0:07:24.280
<v Speaker 1>most magnificent ship you had ever seen, tons and tons

0:07:24.280 --> 0:07:25.960
<v Speaker 1>of guns on it. They put a whole bunch of

0:07:25.960 --> 0:07:29.280
<v Speaker 1>men on it launched it immediately at capsized sank everyone

0:07:29.360 --> 0:07:33.480
<v Speaker 1>died because it was too top heavy. Now, the mary

0:07:33.560 --> 0:07:36.360
<v Speaker 1>Rose had a different design where you could have guns

0:07:36.400 --> 0:07:39.000
<v Speaker 1>on the deck and guns on a gun deck beneath

0:07:39.080 --> 0:07:45.360
<v Speaker 1>the the deck deck de yeah, okay deck and this

0:07:45.360 --> 0:07:47.320
<v Speaker 1>this was that sounds like it's kind of you know,

0:07:47.360 --> 0:07:50.480
<v Speaker 1>basic stuff, but this is the sort of technology that

0:07:51.000 --> 0:07:54.760
<v Speaker 1>that Europeans began to depend upon in naval warfare, which

0:07:54.960 --> 0:07:59.520
<v Speaker 1>started to play a larger role from about fifteen onward. Um.

0:07:59.520 --> 0:08:01.680
<v Speaker 1>And when I say that the mary Rose was the

0:08:01.720 --> 0:08:03.960
<v Speaker 1>flagship of the British Navy, you should keep in mind

0:08:04.000 --> 0:08:06.360
<v Speaker 1>that the British Navy at that time consisted of about

0:08:06.480 --> 0:08:09.720
<v Speaker 1>thirty ships total. Yeah, and a lot of those were

0:08:09.760 --> 0:08:13.800
<v Speaker 1>merchant ships that had been conscripted into the navy. You know,

0:08:13.840 --> 0:08:16.840
<v Speaker 1>cannon at that time were not made of cast iron.

0:08:17.320 --> 0:08:21.400
<v Speaker 1>They were made of wrought iron and bronze um. But

0:08:21.480 --> 0:08:25.080
<v Speaker 1>they did have exploding shot yes um, which would I

0:08:25.080 --> 0:08:27.800
<v Speaker 1>imagine be pretty nasty if you happen to be on

0:08:27.800 --> 0:08:29.800
<v Speaker 1>one of the other ships. Yeah, it's not something you

0:08:29.840 --> 0:08:33.240
<v Speaker 1>want to get hit with. Uh. And and bronze cannon

0:08:33.640 --> 0:08:37.400
<v Speaker 1>they were lighter than uh, than your iron cannon, but

0:08:37.559 --> 0:08:41.680
<v Speaker 1>they were much more expensive than iron cannons. Uh. So

0:08:42.080 --> 0:08:44.959
<v Speaker 1>you again, it would depend upon the wealth of the

0:08:45.040 --> 0:08:48.400
<v Speaker 1>nation or ship owner as to what kind of cannon

0:08:48.440 --> 0:08:51.200
<v Speaker 1>would be on that ship, as well as the the

0:08:51.240 --> 0:08:53.760
<v Speaker 1>seaworthiness of the ship itself. I mean, if a ship

0:08:54.080 --> 0:08:59.360
<v Speaker 1>couldn't carry that many iron cannon, they might choose to

0:08:59.400 --> 0:09:01.480
<v Speaker 1>spend the money need to get the bronze cannon instead.

0:09:03.160 --> 0:09:06.320
<v Speaker 1>And of course those those cannon were more likely to

0:09:06.440 --> 0:09:11.680
<v Speaker 1>be a matchlock. Yeah, let's let's talk about matchlocks for

0:09:11.720 --> 0:09:16.199
<v Speaker 1>a second. It's an interesting technology. So before the matchlock

0:09:17.000 --> 0:09:21.600
<v Speaker 1>was invented, the way that guns worked in the Middle Ages, well,

0:09:21.960 --> 0:09:25.800
<v Speaker 1>the earliest guns were essentially just a barrel with a

0:09:25.840 --> 0:09:28.600
<v Speaker 1>hole in them on on well, you know, a little

0:09:28.640 --> 0:09:31.120
<v Speaker 1>hole drilled at the top of the barrel on the

0:09:31.120 --> 0:09:34.160
<v Speaker 1>the the end that the gun that the shot does

0:09:34.200 --> 0:09:37.800
<v Speaker 1>not come out of handle basically yeah, where the stock is, yeah,

0:09:37.880 --> 0:09:40.320
<v Speaker 1>or where the stock would be if we're talking, Yeah,

0:09:40.360 --> 0:09:43.960
<v Speaker 1>that's true, because we're not talking about about personal weapons.

0:09:43.960 --> 0:09:47.480
<v Speaker 1>We're talking like a cannon cannon. There were some handheld

0:09:48.080 --> 0:09:50.040
<v Speaker 1>weapons as well, but they were very difficult to use

0:09:50.559 --> 0:09:53.120
<v Speaker 1>and required more than one person generally, Yeah, because you

0:09:53.160 --> 0:09:56.360
<v Speaker 1>couldn't just yeah, exactly one hand. We haven't gotten to

0:09:56.400 --> 0:09:58.719
<v Speaker 1>that part. We're gonna get to that part. So you've

0:09:58.720 --> 0:10:01.199
<v Speaker 1>gotta you've gotta hold drilled that end and uh, this

0:10:01.280 --> 0:10:04.240
<v Speaker 1>is where you would put a burning wick through the

0:10:04.280 --> 0:10:08.680
<v Speaker 1>whole hole to ignite the gunpowder that's inside the barrel. Yes,

0:10:08.679 --> 0:10:11.360
<v Speaker 1>because the shot is uh you know, closer to the end,

0:10:11.520 --> 0:10:13.959
<v Speaker 1>the other end of the barrel, um and you have

0:10:14.040 --> 0:10:18.480
<v Speaker 1>the gunpowder behind that pelt. Yeah, So the gunpowder ignites

0:10:18.600 --> 0:10:21.040
<v Speaker 1>and as it ignites, it gives off quite a bit

0:10:21.080 --> 0:10:23.960
<v Speaker 1>of gas, and that gas is what expels the shot

0:10:24.679 --> 0:10:28.679
<v Speaker 1>from the barrel. Uh. So that meant that you had

0:10:28.679 --> 0:10:31.959
<v Speaker 1>to have at least one hand to hold a a

0:10:32.000 --> 0:10:35.040
<v Speaker 1>lit match or a wick of some sort to insert

0:10:35.080 --> 0:10:37.520
<v Speaker 1>it in the hole. Which does mean that if you

0:10:37.520 --> 0:10:39.760
<v Speaker 1>are just one single person and you have one of

0:10:39.760 --> 0:10:42.000
<v Speaker 1>these rifles, you only have one hand to aim it

0:10:42.040 --> 0:10:44.320
<v Speaker 1>with while you're using the other hand to light it.

0:10:44.320 --> 0:10:49.240
<v Speaker 1>It's not the most accurate weapon. The matchlock kind of

0:10:49.280 --> 0:10:51.839
<v Speaker 1>made this, uh, took that out of your hands and

0:10:52.000 --> 0:10:54.920
<v Speaker 1>put it into a mechanical hand, so to speak. I mean,

0:10:54.920 --> 0:10:57.640
<v Speaker 1>there was a there was something called a serpentine, which

0:10:57.640 --> 0:11:01.199
<v Speaker 1>is an S shaped trigger and basely uh. At one

0:11:01.280 --> 0:11:03.760
<v Speaker 1>end of the S you have your match and at

0:11:03.800 --> 0:11:05.679
<v Speaker 1>the other end is where your finger goes, and when

0:11:05.679 --> 0:11:08.520
<v Speaker 1>you move it, it basically pivoted in the center, so

0:11:08.559 --> 0:11:10.960
<v Speaker 1>that when you pull the trigger, it would bring the

0:11:10.960 --> 0:11:14.600
<v Speaker 1>match down and that would you know, and the flash

0:11:14.640 --> 0:11:17.400
<v Speaker 1>pan and it would set off the charge essentially. So

0:11:17.480 --> 0:11:19.720
<v Speaker 1>the way the flash pan works is that, you know,

0:11:19.960 --> 0:11:22.560
<v Speaker 1>we talked about that that earlier example, you had a

0:11:22.600 --> 0:11:25.240
<v Speaker 1>hole that you had to put the match through. The

0:11:25.280 --> 0:11:27.760
<v Speaker 1>flash pan takes that part out of it. The flash

0:11:27.800 --> 0:11:30.760
<v Speaker 1>pan holds a small amount of gunpowder that then leads

0:11:30.800 --> 0:11:33.680
<v Speaker 1>from right, that leads in through a hole in the

0:11:33.720 --> 0:11:36.920
<v Speaker 1>barrel to a larger charge of gunpowder. That's the part

0:11:36.960 --> 0:11:40.920
<v Speaker 1>that actually propels the shot. And by lighting the flash pan,

0:11:41.600 --> 0:11:43.640
<v Speaker 1>the you know, it's like those old movies where you know,

0:11:43.679 --> 0:11:45.520
<v Speaker 1>you light the one end of the gunpowder and it

0:11:45.559 --> 0:11:49.160
<v Speaker 1>goes down the line and the lights the big barrel

0:11:49.200 --> 0:11:51.640
<v Speaker 1>at the end, singing sort of concept, except into much

0:11:51.679 --> 0:11:54.600
<v Speaker 1>smaller space. You're you light the flash flash pan, the

0:11:54.600 --> 0:11:58.520
<v Speaker 1>gunpowder lights through the hole in the barrel. Lighting the

0:11:58.559 --> 0:12:01.360
<v Speaker 1>main charge in the barrel of the gun fires off

0:12:01.360 --> 0:12:05.080
<v Speaker 1>the shot. So, yeah, the matchlock meant that you just

0:12:05.080 --> 0:12:08.640
<v Speaker 1>pulled the little trigger and it would bring the the

0:12:08.720 --> 0:12:12.560
<v Speaker 1>lit fuse in contact with the flashpan. Eventually, you would

0:12:12.559 --> 0:12:16.360
<v Speaker 1>get a flashpan cover over that that would also be

0:12:16.400 --> 0:12:18.320
<v Speaker 1>hooked up to the trigger, so that when you pulled

0:12:18.320 --> 0:12:21.000
<v Speaker 1>the trigger, the flashpan cover would slide out of the

0:12:21.040 --> 0:12:23.920
<v Speaker 1>way as the fuse comes down. And that was important

0:12:23.960 --> 0:12:26.760
<v Speaker 1>to protect the powder because, of course, if the powder

0:12:26.800 --> 0:12:29.480
<v Speaker 1>were to get wet, yes, that's a problem, your gun

0:12:29.720 --> 0:12:35.600
<v Speaker 1>was useless exactly. Yeah, so even foggy conditions could mess

0:12:35.679 --> 0:12:39.559
<v Speaker 1>up the effectiveness of a gun. And when we talk

0:12:39.600 --> 0:12:41.920
<v Speaker 1>about guns, we're talking mainly we're talking about cannon. We're

0:12:41.920 --> 0:12:46.280
<v Speaker 1>talking about the arquebus um, which was a a personal

0:12:46.320 --> 0:12:49.480
<v Speaker 1>weapon you could it was essentially the the precursor to

0:12:49.480 --> 0:12:52.640
<v Speaker 1>the musket and uh, which of course is precursor to

0:12:52.679 --> 0:12:59.120
<v Speaker 1>the rifle, and it ended up revolutionizing warfare. Yeah. Well,

0:12:59.160 --> 0:13:02.000
<v Speaker 1>the arquebus all so had a some people called it

0:13:02.040 --> 0:13:05.319
<v Speaker 1>a heck butt because it had a basically a little

0:13:05.400 --> 0:13:09.400
<v Speaker 1>hook on it. And uh, what would happen is, you know,

0:13:09.760 --> 0:13:12.720
<v Speaker 1>castles were sort of going through a technological change too,

0:13:12.760 --> 0:13:16.760
<v Speaker 1>because now that uh, people were beginning to use firearms,

0:13:16.960 --> 0:13:20.920
<v Speaker 1>personal firearms, not just cannon. Um. You know, they needed

0:13:20.920 --> 0:13:23.560
<v Speaker 1>a way too. They had all these arrow slits in

0:13:23.640 --> 0:13:26.440
<v Speaker 1>the walls of the castle which needed to be you know,

0:13:27.360 --> 0:13:31.520
<v Speaker 1>which people needed to use for their firearms. So the

0:13:31.520 --> 0:13:34.520
<v Speaker 1>thing is is, as you mentioned before, Jonathan, they the

0:13:34.600 --> 0:13:37.320
<v Speaker 1>powder and these weapons gave off a lot of gas

0:13:37.440 --> 0:13:40.080
<v Speaker 1>and had you know, packed a bit of a wallop.

0:13:40.360 --> 0:13:44.959
<v Speaker 1>We're talking about a you know, recoil, and so that's

0:13:44.960 --> 0:13:47.000
<v Speaker 1>what the hook was for. Basically, you'd use the hook

0:13:47.320 --> 0:13:50.000
<v Speaker 1>to hook over the uh the stone wall of the

0:13:50.040 --> 0:13:52.760
<v Speaker 1>castle to keep it from you know, knocking you back

0:13:53.440 --> 0:13:57.520
<v Speaker 1>as you fired the weapon wall of the castle. Uh. Yeah,

0:13:57.559 --> 0:14:01.880
<v Speaker 1>castles actually ended up becoming both castles and armor became

0:14:02.000 --> 0:14:05.520
<v Speaker 1>less and less important as gunpowder became more important because

0:14:05.640 --> 0:14:08.520
<v Speaker 1>they didn't provide much of a of a protection and

0:14:08.559 --> 0:14:15.240
<v Speaker 1>so uh, countries had to readjust the way they conducted warfare. Um.

0:14:15.320 --> 0:14:17.400
<v Speaker 1>And it wasn't like the old days where you just

0:14:17.480 --> 0:14:19.600
<v Speaker 1>got a bunch of people all in various kinds of

0:14:19.680 --> 0:14:22.440
<v Speaker 1>armor and then had them clashed together, or you hold

0:14:22.520 --> 0:14:24.800
<v Speaker 1>up in a castle and tried to wait out a siege.

0:14:25.040 --> 0:14:28.840
<v Speaker 1>You couldn't really do that in an arrow where the

0:14:28.840 --> 0:14:31.480
<v Speaker 1>basic weapons could punch holes through your walls like there

0:14:31.520 --> 0:14:34.440
<v Speaker 1>were nothing. Yeah, yeah, that's true. You know. It kind

0:14:34.440 --> 0:14:36.200
<v Speaker 1>of bummed out that we didn't get to talk in

0:14:36.280 --> 0:14:41.760
<v Speaker 1>great detail about flint lock and the wheel lock mechanisms yet. No. No,

0:14:41.920 --> 0:14:45.160
<v Speaker 1>although the wheelock apparently was developed around fifteen fifteen, so

0:14:45.200 --> 0:14:47.880
<v Speaker 1>it's not much in the future. And depending on who

0:14:47.960 --> 0:14:50.880
<v Speaker 1>you asked, they might say that flintlocks were around. But

0:14:50.960 --> 0:14:55.160
<v Speaker 1>really flintlocks, I mean, people didn't document stuff is accurately.

0:14:55.400 --> 0:14:57.480
<v Speaker 1>It turns out it turns out the guy didn't wake

0:14:57.560 --> 0:15:03.200
<v Speaker 1>up and July fourteen invented the flintlock. Today that doesn't

0:15:03.520 --> 0:15:06.040
<v Speaker 1>turns out that didn't happen. But interesting bit of trivia.

0:15:06.040 --> 0:15:08.800
<v Speaker 1>I found out the reason that these are called fill

0:15:08.800 --> 0:15:12.000
<v Speaker 1>in the blank here lock was because locksmiths used to

0:15:12.000 --> 0:15:16.000
<v Speaker 1>work with a lot of them mechanisms similar to what

0:15:16.200 --> 0:15:19.960
<v Speaker 1>you know the kinds of technology used here. So if

0:15:19.960 --> 0:15:23.960
<v Speaker 1>you wanted these things built for your weaponry, you would

0:15:23.960 --> 0:15:27.440
<v Speaker 1>consult with a locksmith who would work on the little,

0:15:27.480 --> 0:15:30.040
<v Speaker 1>tiny little pieces that you would need to add to

0:15:30.080 --> 0:15:33.080
<v Speaker 1>your firearms. That makes it interesting. Yeah, it makes sense,

0:15:33.120 --> 0:15:35.280
<v Speaker 1>you know, because you think you know that there were

0:15:35.280 --> 0:15:40.480
<v Speaker 1>no our definitions hadn't really taken effect there. We don't.

0:15:40.520 --> 0:15:42.640
<v Speaker 1>We don't have the same things like engineers the way

0:15:42.680 --> 0:15:46.120
<v Speaker 1>we have engineers. Now, you had philosophers, you had scientists,

0:15:46.160 --> 0:15:51.520
<v Speaker 1>a various uh rudimentary sciences at the time, although again

0:15:51.520 --> 0:15:53.080
<v Speaker 1>if you go to the Middle East they were much

0:15:53.120 --> 0:15:56.240
<v Speaker 1>further along and in China as well. Uh. Well, I

0:15:56.280 --> 0:15:58.440
<v Speaker 1>was gonna talk also a couple of other things that

0:15:58.480 --> 0:16:01.920
<v Speaker 1>are related to guns. Oh yeah, because because we're gotting crazy.

0:16:02.160 --> 0:16:04.680
<v Speaker 1>Um well, it was. It was awfully prominent too. Yeah.

0:16:04.760 --> 0:16:06.920
<v Speaker 1>A lot of the technology in the Middle Ages dealt

0:16:06.960 --> 0:16:10.040
<v Speaker 1>with warfare. Yeah, I mean it just that was you

0:16:10.080 --> 0:16:14.320
<v Speaker 1>think about invention and uh you know the whole necessity

0:16:14.440 --> 0:16:16.920
<v Speaker 1>driving invention. Well, in the Middle Ages, it was pretty

0:16:17.000 --> 0:16:19.560
<v Speaker 1>much necessary for you to be able to attack and

0:16:19.600 --> 0:16:23.040
<v Speaker 1>defend um, because that's pretty much what the entire history

0:16:23.160 --> 0:16:27.760
<v Speaker 1>was about in large part. So one of the interesting

0:16:28.960 --> 0:16:32.680
<v Speaker 1>things that made cannon very possible actually a couple of

0:16:32.680 --> 0:16:37.400
<v Speaker 1>different inventions. One of them was the trunyon. Trunion is

0:16:37.440 --> 0:16:40.280
<v Speaker 1>a fancy word for the posts that stick out the

0:16:40.320 --> 0:16:42.320
<v Speaker 1>side of a cannon that allow you to change the

0:16:42.320 --> 0:16:44.800
<v Speaker 1>elevation of the cannon. Oh. I figured it was a

0:16:44.840 --> 0:16:47.520
<v Speaker 1>combination of a truffle and an onion. No, but that

0:16:47.600 --> 0:16:51.320
<v Speaker 1>does sound tasty. Now this, uh, this was just what

0:16:51.400 --> 0:16:54.400
<v Speaker 1>allowed you to pivot a cannon upward or downward so

0:16:54.440 --> 0:16:57.040
<v Speaker 1>that you can name it instead of it just pointing

0:16:57.040 --> 0:17:00.480
<v Speaker 1>in a direction hoping that that's good enough, right, um.

0:17:00.560 --> 0:17:04.280
<v Speaker 1>And then you had limbers. Limbers are these two wheeled

0:17:05.160 --> 0:17:08.119
<v Speaker 1>devices that you could hook up to a carriage. You

0:17:08.160 --> 0:17:11.000
<v Speaker 1>would mount a gun on them, and it just made

0:17:11.000 --> 0:17:15.600
<v Speaker 1>it easier for you to um to transport artillery. That

0:17:15.680 --> 0:17:18.879
<v Speaker 1>was another big change by this time in the Middle Ages.

0:17:19.119 --> 0:17:20.800
<v Speaker 1>Earlier in the Middle Ages, if you wanted to lay

0:17:20.840 --> 0:17:24.680
<v Speaker 1>siege to a castle, you either had to have large

0:17:24.760 --> 0:17:28.359
<v Speaker 1>artillery pieces that you could assemble once you got there,

0:17:28.840 --> 0:17:31.960
<v Speaker 1>or you were using things like um trebisches or even

0:17:32.400 --> 0:17:37.040
<v Speaker 1>if you're using even older technology ballista and catapults. And

0:17:37.080 --> 0:17:40.119
<v Speaker 1>just so you guys know, uh, those are technologies that

0:17:40.880 --> 0:17:44.840
<v Speaker 1>use basic physics to propel a projectile a very far

0:17:44.880 --> 0:17:48.480
<v Speaker 1>away with a lot of force. These days pumpkins, yes,

0:17:48.840 --> 0:17:52.960
<v Speaker 1>so like a catapult would use uh rope, yes that

0:17:53.080 --> 0:17:57.240
<v Speaker 1>had been wound very tightly a skein. Actually it's wound

0:17:57.320 --> 0:18:00.119
<v Speaker 1>very very tightly, and that would be enough to you.

0:18:00.320 --> 0:18:02.480
<v Speaker 1>You know, you stick one end of the catapult through

0:18:02.520 --> 0:18:04.960
<v Speaker 1>that that rope and then you wind it really tight,

0:18:05.000 --> 0:18:08.199
<v Speaker 1>and that provides the tension that when you release it,

0:18:08.200 --> 0:18:11.359
<v Speaker 1>it makes the arm go up until it hits arrest,

0:18:11.440 --> 0:18:15.080
<v Speaker 1>and then that propels a projectile. Ballista used two of those.

0:18:15.920 --> 0:18:18.120
<v Speaker 1>It looked like a giant crossbow, but in fact used

0:18:18.200 --> 0:18:23.439
<v Speaker 1>two um uh skeins to propel a projectile. And then

0:18:23.440 --> 0:18:25.800
<v Speaker 1>the trebuche was a little different. It was a sling

0:18:25.840 --> 0:18:28.080
<v Speaker 1>on the end of a long arm. Um it was

0:18:28.080 --> 0:18:29.720
<v Speaker 1>actually a lever, So he had a long end of

0:18:29.760 --> 0:18:32.000
<v Speaker 1>the lever which had the the sling attached to it,

0:18:32.040 --> 0:18:34.000
<v Speaker 1>and then on the short end you had a counterweight,

0:18:34.560 --> 0:18:37.760
<v Speaker 1>a very very heavy counterweight, and when you released the

0:18:37.760 --> 0:18:41.240
<v Speaker 1>the mechanism on it, the counterweight would fall down, propelling

0:18:41.320 --> 0:18:46.159
<v Speaker 1>the long arm up and flinging whatever the projectile was

0:18:46.240 --> 0:18:49.880
<v Speaker 1>in the direction of your target. And those were all

0:18:50.400 --> 0:18:54.880
<v Speaker 1>the older forms of projectile weaponry that essentially got phased

0:18:54.880 --> 0:18:59.280
<v Speaker 1>out once cannon became a real player in the Middle Ages,

0:19:00.560 --> 0:19:02.080
<v Speaker 1>but you probably still saw a few of them in

0:19:02.680 --> 0:19:07.720
<v Speaker 1>depending on where you were. Um, so are we done

0:19:07.720 --> 0:19:10.359
<v Speaker 1>with military type stuff? I was going to talk about

0:19:10.400 --> 0:19:13.040
<v Speaker 1>plate armor. You want to talk about plate armor just

0:19:13.080 --> 0:19:20.160
<v Speaker 1>a little bit. Go ahead in the iron is still king. Yes,

0:19:20.240 --> 0:19:22.359
<v Speaker 1>you're gonna see a lot of iron armor. You're not

0:19:22.359 --> 0:19:24.920
<v Speaker 1>going to see very much steel. Steel was being made,

0:19:24.920 --> 0:19:29.000
<v Speaker 1>but it was incredibly difficult to make. UM. To make steel,

0:19:29.000 --> 0:19:32.200
<v Speaker 1>you had to heat iron up quite quite hot, introduce

0:19:32.280 --> 0:19:34.560
<v Speaker 1>carbon into it, but not too much carbon, because if

0:19:34.560 --> 0:19:36.600
<v Speaker 1>you put too much carbon in it, you got pig iron,

0:19:37.320 --> 0:19:39.800
<v Speaker 1>which is not great for armor. As it turns out,

0:19:40.040 --> 0:19:44.160
<v Speaker 1>kind of shatters um details one enough carbon in there

0:19:44.200 --> 0:19:47.240
<v Speaker 1>to make the iron hard, but not so much that

0:19:47.359 --> 0:19:51.080
<v Speaker 1>it becomes brittle. Has to still be malleable. So steel

0:19:51.240 --> 0:19:55.840
<v Speaker 1>is actually pretty complicated. It's really expensive. UM. Most armor

0:19:55.960 --> 0:19:58.159
<v Speaker 1>is made out of iron. But at this point you

0:19:58.200 --> 0:20:01.880
<v Speaker 1>do see full plate suits of armor, and full plate

0:20:01.960 --> 0:20:05.480
<v Speaker 1>that means that there's there these various hinged plates that

0:20:05.800 --> 0:20:09.720
<v Speaker 1>cover the entire body UM that provide as much freedom

0:20:09.720 --> 0:20:12.840
<v Speaker 1>of movement as possible while still providing as much protection

0:20:12.920 --> 0:20:17.919
<v Speaker 1>as possible, and full plate armor depending on you know

0:20:18.200 --> 0:20:20.439
<v Speaker 1>what kind of the quality of the iron or steel

0:20:20.520 --> 0:20:24.399
<v Speaker 1>that was used to make it. Could even ward off

0:20:25.200 --> 0:20:30.160
<v Speaker 1>a shot from an arquebus at the right range if

0:20:30.160 --> 0:20:33.359
<v Speaker 1>you're right up close to someone, chances are that SHOT's

0:20:33.400 --> 0:20:35.520
<v Speaker 1>gonna go right through the armor and into you, which

0:20:35.520 --> 0:20:39.720
<v Speaker 1>is bad news. But um, but that's still in. It

0:20:39.800 --> 0:20:44.400
<v Speaker 1>was still fairly common to see soldiers wearing this kind

0:20:44.400 --> 0:20:47.200
<v Speaker 1>of armor because the guns had not reached a point

0:20:47.200 --> 0:20:52.680
<v Speaker 1>of sophistication where they had rendered it completely obsolete, and

0:20:52.760 --> 0:20:54.560
<v Speaker 1>Henry the Eighth himself was known to wear it quite

0:20:54.560 --> 0:20:57.800
<v Speaker 1>a few times. He actually entered a lot of attorneys

0:20:58.800 --> 0:21:02.000
<v Speaker 1>um secretly in fact, uh, in fact, I think a

0:21:02.119 --> 0:21:05.879
<v Speaker 1>year after he was coronated, he entered a tournament in

0:21:05.960 --> 0:21:10.040
<v Speaker 1>secret and gained quite a bit of respect because he

0:21:10.080 --> 0:21:16.160
<v Speaker 1>was a very gifted combatant. Wow, yeah, I had no idea. Yeah,

0:21:16.440 --> 0:21:20.960
<v Speaker 1>not a great wrestler. But King of France beat him

0:21:20.960 --> 0:21:24.480
<v Speaker 1>in a wrestling match that was at the the Fields

0:21:24.520 --> 0:21:30.760
<v Speaker 1>of Cloth and Gold. Alright, now I'm done with the

0:21:30.800 --> 0:21:33.760
<v Speaker 1>military stuff, okay, Because one one technology that I found

0:21:33.760 --> 0:21:37.879
<v Speaker 1>that was apparently created fairly close to fifteen ten was

0:21:37.920 --> 0:21:44.520
<v Speaker 1>the watch. Yes by Germany's Peter henlen Um. He was

0:21:44.560 --> 0:21:48.040
<v Speaker 1>in a Nurnberg, Germany and um, which at that point

0:21:48.119 --> 0:21:53.920
<v Speaker 1>wasn't technically Germany because Germany didn't technically exist as a country. Um.

0:21:53.960 --> 0:21:57.800
<v Speaker 1>But some people say that I actually I had seen

0:21:57.840 --> 0:22:00.399
<v Speaker 1>reports that it was in fact invented like the pocket

0:22:00.400 --> 0:22:05.160
<v Speaker 1>watch invented in but there appeared to have been prototypes

0:22:05.400 --> 0:22:08.720
<v Speaker 1>existing as early as maybe fifteen o five or so.

0:22:08.760 --> 0:22:11.760
<v Speaker 1>That's pretty close. And again, this is something that I

0:22:11.800 --> 0:22:14.919
<v Speaker 1>think of is having been around since, you know, forever

0:22:15.000 --> 0:22:17.520
<v Speaker 1>and ever, so to speak in the case of this.

0:22:17.680 --> 0:22:21.639
<v Speaker 1>But uh no, the the watches starting to make its

0:22:21.680 --> 0:22:24.640
<v Speaker 1>appearance around the early sixteenth century, I imagine they would

0:22:24.640 --> 0:22:27.440
<v Speaker 1>be very expensive and probably not very reliable. And the

0:22:27.720 --> 0:22:32.080
<v Speaker 1>secret to the watch was the fuse, which is uh

0:22:32.320 --> 0:22:34.560
<v Speaker 1>this is a little complicated. It's kind of hard to explain.

0:22:34.640 --> 0:22:38.160
<v Speaker 1>But a watch is the thing that powers these classic

0:22:38.200 --> 0:22:42.840
<v Speaker 1>watches as a spring inside the watch, and uh around

0:22:42.920 --> 0:22:46.320
<v Speaker 1>the spring is a barrel. When the spring is wound tight,

0:22:46.480 --> 0:22:50.040
<v Speaker 1>it then turns the barrel. So attached to this barrel

0:22:50.280 --> 0:22:53.920
<v Speaker 1>is a little chain. The chain goes to a cone

0:22:54.440 --> 0:22:57.760
<v Speaker 1>that has um grooves in it. Yeah, all right, So

0:22:57.840 --> 0:23:00.199
<v Speaker 1>the attaches to at the top of the cone and

0:23:00.240 --> 0:23:02.359
<v Speaker 1>the chain winds around all the way to the base

0:23:02.400 --> 0:23:07.119
<v Speaker 1>of the cone. All right. As the spring unfurls and

0:23:07.160 --> 0:23:10.879
<v Speaker 1>the barrel turns, it pulls the chain from this Uh,

0:23:10.920 --> 0:23:14.159
<v Speaker 1>this fuse, this cone and the chain goes from the

0:23:14.200 --> 0:23:16.960
<v Speaker 1>top down to the bottom. And once it gets to

0:23:16.960 --> 0:23:20.080
<v Speaker 1>the bottom, that's when your watch has needs to be

0:23:20.200 --> 0:23:23.119
<v Speaker 1>wound again. When you wind it, you're actually winding that

0:23:23.200 --> 0:23:25.960
<v Speaker 1>chain around the cone again. This is what provides the

0:23:26.000 --> 0:23:29.720
<v Speaker 1>power to the watch hands to to go around the

0:23:29.760 --> 0:23:32.400
<v Speaker 1>clock face. Earliest earlier clocks, by the way, I only

0:23:32.400 --> 0:23:36.560
<v Speaker 1>had one hand. They had one hand that indicated where

0:23:36.600 --> 0:23:38.359
<v Speaker 1>in the hour it was, so you still had the

0:23:38.359 --> 0:23:40.880
<v Speaker 1>twelve numbers, but you would look and if the hand

0:23:40.960 --> 0:23:43.679
<v Speaker 1>was between the you know, one and the two, you'd think,

0:23:43.720 --> 0:23:46.320
<v Speaker 1>all right, well it's about one thirty. It's about as

0:23:46.000 --> 0:23:49.600
<v Speaker 1>as close as you would get. Um. But yeah, that's

0:23:49.440 --> 0:23:53.040
<v Speaker 1>the fuse is what allowed both pocket watches and you know,

0:23:53.119 --> 0:23:56.160
<v Speaker 1>table clocks to exist because before that you had to

0:23:56.280 --> 0:24:00.720
<v Speaker 1>use weights to to power the clock. Theist watch came

0:24:00.720 --> 0:24:08.040
<v Speaker 1>around much much later, Yeah, swatch even later. Imagine. Yeah, Um,

0:24:08.240 --> 0:24:10.400
<v Speaker 1>another technology I was thinking about that would have been

0:24:11.680 --> 0:24:14.320
<v Speaker 1>it had been out for a few decades, but you

0:24:14.359 --> 0:24:18.880
<v Speaker 1>know that the movable type Gutenberg. Yes, so we're going

0:24:18.880 --> 0:24:22.199
<v Speaker 1>back to fourteen fifty five or so. Yeah, yeah, but

0:24:23.119 --> 0:24:26.119
<v Speaker 1>you know it was making an impact and and was

0:24:26.119 --> 0:24:29.400
<v Speaker 1>spreading very rapidly around the turn of the century. Now,

0:24:29.440 --> 0:24:33.320
<v Speaker 1>movable type was new to the Western world, although in

0:24:33.480 --> 0:24:35.840
<v Speaker 1>China they had they had had movable type for a

0:24:35.840 --> 0:24:40.359
<v Speaker 1>few centuries, but um, but then in it did really

0:24:40.400 --> 0:24:47.080
<v Speaker 1>revolutionize learning in medieval Europe. Of certainly made printing much

0:24:47.080 --> 0:24:50.240
<v Speaker 1>more inexpensive. Right up to that point, you essentially would

0:24:50.240 --> 0:24:53.680
<v Speaker 1>get printing by hiring monks to write a text for you.

0:24:54.720 --> 0:24:57.600
<v Speaker 1>And that's where you got those beautiful illuminated scripts where

0:24:57.680 --> 0:25:01.000
<v Speaker 1>it was amazing calligraphy, and you know, you figured that

0:25:01.000 --> 0:25:05.480
<v Speaker 1>they must have been paid by the brushstroke. But the

0:25:05.480 --> 0:25:07.399
<v Speaker 1>the movable type, yea, you took a lot of the

0:25:07.600 --> 0:25:10.280
<v Speaker 1>maybe the artistry out of it. But in turn you

0:25:10.320 --> 0:25:13.600
<v Speaker 1>made it much easier to produce lots and lots of copies.

0:25:13.760 --> 0:25:18.120
<v Speaker 1>And so that that's really what propelled the whole renaissance

0:25:18.119 --> 0:25:20.440
<v Speaker 1>in all of Europe, was the fact that you suddenly

0:25:20.480 --> 0:25:24.679
<v Speaker 1>had this this easy access, relatively easy access to printed works.

0:25:25.480 --> 0:25:27.560
<v Speaker 1>You know, althy're thinking about it. If the monks are

0:25:27.600 --> 0:25:31.639
<v Speaker 1>copying a book word for word, wouldn't that be a

0:25:31.680 --> 0:25:37.000
<v Speaker 1>form of desktop publishing. So anyway, uh, let's talk about

0:25:37.200 --> 0:25:40.600
<v Speaker 1>a true renaissance. Man, Yes, Leonardo da Vinci, since I

0:25:40.800 --> 0:25:44.320
<v Speaker 1>truly messed up the Renaissance. Uh, you should have stopped me.

0:25:44.840 --> 0:25:47.080
<v Speaker 1>How did I how did you mess up the Renaissance? Well,

0:25:47.119 --> 0:25:50.800
<v Speaker 1>then we weren't talking about anyway. The Renaissance man Leonard's

0:25:51.080 --> 0:25:55.280
<v Speaker 1>Leonardo da Vinci. Da Vinci, of course was towards the

0:25:55.359 --> 0:25:59.160
<v Speaker 1>end of his life. Yes, yes, he died in fifteen nineteen. Um,

0:25:59.240 --> 0:26:02.719
<v Speaker 1>he was, uh a real genius. I mean not just

0:26:02.840 --> 0:26:06.080
<v Speaker 1>an amazing artist, but an inventor. And of course he

0:26:06.119 --> 0:26:10.480
<v Speaker 1>had that great code. So anyway, and then actually, and

0:26:10.520 --> 0:26:14.119
<v Speaker 1>actually it turns out it was around uh some of

0:26:14.160 --> 0:26:16.359
<v Speaker 1>the time when he was coming up with scientific ideas,

0:26:16.359 --> 0:26:19.280
<v Speaker 1>he wasn't doing as much painting. He was teaching that.

0:26:19.480 --> 0:26:22.360
<v Speaker 1>He did do the Mona Lisa towards that time period,

0:26:22.640 --> 0:26:25.280
<v Speaker 1>but he had already done the Last Supper, and um,

0:26:25.359 --> 0:26:28.040
<v Speaker 1>yeah he was. He was thinking of inventions. He had

0:26:28.040 --> 0:26:30.159
<v Speaker 1>already kind of come up with the whole idea about

0:26:30.480 --> 0:26:34.440
<v Speaker 1>powered flight, which never worked during his lifetime. But he

0:26:34.760 --> 0:26:38.080
<v Speaker 1>did work out the basic principles of things like lift,

0:26:38.680 --> 0:26:40.800
<v Speaker 1>which no one had really managed to do up to

0:26:40.840 --> 0:26:44.960
<v Speaker 1>that point. Um, around fifteen he actually drew the first

0:26:45.320 --> 0:26:49.639
<v Speaker 1>documented sketch of a fetus in the womb. Yeah, seven

0:26:49.640 --> 0:26:52.560
<v Speaker 1>months old, I did that was the fetus his age.

0:26:52.680 --> 0:26:57.600
<v Speaker 1>Leonardo was significantly older than that. I didn't notice that

0:26:57.600 --> 0:27:00.280
<v Speaker 1>that period two was when he was really in did

0:27:00.280 --> 0:27:02.680
<v Speaker 1>in the Anatomy of the human body, So that makes

0:27:02.680 --> 0:27:05.440
<v Speaker 1>sense that that would have been was a little after

0:27:05.480 --> 0:27:08.560
<v Speaker 1>he had drawn the Vitruvian Man, which is the infamous

0:27:09.760 --> 0:27:12.760
<v Speaker 1>painting that he did to show the proportions of the

0:27:12.840 --> 0:27:16.520
<v Speaker 1>human body. Did you know that for most people, the

0:27:16.640 --> 0:27:19.520
<v Speaker 1>length of your pinkie is the same as the length

0:27:19.880 --> 0:27:22.760
<v Speaker 1>of your nose if you lay it down on the

0:27:22.760 --> 0:27:25.840
<v Speaker 1>bridge of your nose. Yeah, you know who? I learned

0:27:25.840 --> 0:27:29.800
<v Speaker 1>that from Leonardo da Vinci really well, at least the

0:27:29.800 --> 0:27:32.760
<v Speaker 1>one that works at the Georgia Renaissance Festival. I did, um,

0:27:33.280 --> 0:27:36.600
<v Speaker 1>hey Houston, how are you doing so? But yeah, this

0:27:36.680 --> 0:27:39.840
<v Speaker 1>time he also invented, at least according to the sources

0:27:39.880 --> 0:27:42.960
<v Speaker 1>I was reading, a horizontal water wheel, which is kind

0:27:43.000 --> 0:27:47.040
<v Speaker 1>of the the precursor to the turbine. Again, these are

0:27:47.080 --> 0:27:49.720
<v Speaker 1>inventions that actually existed in other parts of the world,

0:27:49.800 --> 0:27:52.960
<v Speaker 1>but in Europe were unheard of at the time. And

0:27:53.200 --> 0:28:00.040
<v Speaker 1>uh also ball bearings, scissors. I was brilliant, so it

0:28:00.080 --> 0:28:03.880
<v Speaker 1>have made a fortune. He could have. He got into

0:28:03.920 --> 0:28:08.800
<v Speaker 1>a lot of trouble too. But he also he also

0:28:08.920 --> 0:28:13.040
<v Speaker 1>drew up UH an invention which was never actually built.

0:28:13.080 --> 0:28:15.800
<v Speaker 1>A lot of Leonardo's inventions were never built. They were

0:28:15.840 --> 0:28:18.320
<v Speaker 1>just sketches or concepts. But he came up with a

0:28:18.359 --> 0:28:21.520
<v Speaker 1>concept that would have essentially been the first tank. It

0:28:21.680 --> 0:28:25.960
<v Speaker 1>was an armored vehicle to protect people withinside during warfare,

0:28:26.000 --> 0:28:28.679
<v Speaker 1>and I think that's pretty impressive. A lot of his

0:28:28.720 --> 0:28:32.800
<v Speaker 1>inventions had to do with various UH kinds of warfare.

0:28:32.800 --> 0:28:36.800
<v Speaker 1>He also drew up plans for an enormous crossbow was

0:28:37.160 --> 0:28:40.200
<v Speaker 1>according to some estimates, supposed to be as as wide

0:28:40.240 --> 0:28:45.400
<v Speaker 1>as a hundred feet. Well, the crossbow was already falling

0:28:45.400 --> 0:28:47.360
<v Speaker 1>out of fashion. The regular crossbow was calling out of

0:28:47.360 --> 0:28:50.120
<v Speaker 1>fashion thanks to you know, the arquebus. I wanted to

0:28:50.120 --> 0:28:52.920
<v Speaker 1>say that again, Yes, the crossbow was a very slow

0:28:53.000 --> 0:28:56.360
<v Speaker 1>way of killing your rhynomes, but but I imagined that

0:28:56.760 --> 0:29:01.600
<v Speaker 1>Leo's version, being much larger, would have more of an effect. Yeah. Again,

0:29:01.600 --> 0:29:03.320
<v Speaker 1>it was never built, but it was definitely one of

0:29:03.320 --> 0:29:04.840
<v Speaker 1>those things that you took a look at the design

0:29:04.840 --> 0:29:07.440
<v Speaker 1>and you thought, wow, I hope nobody gets ahold of one.

0:29:07.440 --> 0:29:10.160
<v Speaker 1>Of these things because if they do I want to move,

0:29:11.400 --> 0:29:15.080
<v Speaker 1>you would have gotten the point and other The interesting

0:29:15.120 --> 0:29:18.320
<v Speaker 1>thing about the Middle Ages and especially around this time,

0:29:18.400 --> 0:29:22.040
<v Speaker 1>is that how slowly technology actually evolved. I mean you

0:29:23.200 --> 0:29:27.600
<v Speaker 1>part of that is just because again before movable type,

0:29:27.600 --> 0:29:32.360
<v Speaker 1>it was really hard to to pursue learning. It took

0:29:32.480 --> 0:29:37.840
<v Speaker 1>real polymaths like da Vinci or uh, you know, other

0:29:37.920 --> 0:29:40.600
<v Speaker 1>geniuses at the time or in other parts of the

0:29:40.600 --> 0:29:43.200
<v Speaker 1>world to really push things forward, which meant that you know,

0:29:43.240 --> 0:29:44.840
<v Speaker 1>you pretty much had to wait because there was just

0:29:44.920 --> 0:29:46.760
<v Speaker 1>there was no way to dedicate your life to that

0:29:46.840 --> 0:29:50.480
<v Speaker 1>kind of thing. Most schools were of a religious nature,

0:29:50.720 --> 0:29:52.920
<v Speaker 1>where you would learn math, and you would learn languages,

0:29:52.920 --> 0:29:55.880
<v Speaker 1>you would learn philosophy, learn lots of important things. But

0:29:55.960 --> 0:29:58.160
<v Speaker 1>it wasn't really you know, you weren't learning to be

0:29:58.200 --> 0:30:01.440
<v Speaker 1>an engineer. You know, you learned on the job. If

0:30:01.480 --> 0:30:03.400
<v Speaker 1>you wanted to be something like that, like an architect,

0:30:03.480 --> 0:30:05.960
<v Speaker 1>you you would become an apprentice and learn your trade

0:30:06.000 --> 0:30:10.280
<v Speaker 1>that way. Um, so progress was very slow. It wasn't

0:30:10.360 --> 0:30:15.360
<v Speaker 1>until really the early Renaissance, when the the the printed

0:30:15.400 --> 0:30:19.040
<v Speaker 1>word was really coming into full play, that you started

0:30:19.040 --> 0:30:21.440
<v Speaker 1>to see the explosion and learning and then the rapid

0:30:21.480 --> 0:30:27.520
<v Speaker 1>development of technology. Wow, you know, and I feel like

0:30:28.000 --> 0:30:29.840
<v Speaker 1>as with as much as we talked about, you know,

0:30:29.880 --> 0:30:32.040
<v Speaker 1>we're sort of running out of time here, but uh,

0:30:32.120 --> 0:30:33.880
<v Speaker 1>you know, there's still far more that we could cover.

0:30:34.240 --> 0:30:37.000
<v Speaker 1>Of course, this is the stuff that our sister podcast

0:30:37.080 --> 0:30:40.440
<v Speaker 1>usually talks about. Yeah, and speaking of which, recently, stuff

0:30:40.480 --> 0:30:43.959
<v Speaker 1>you should know, recorded a podcast about castles, So if

0:30:44.000 --> 0:30:46.239
<v Speaker 1>you have, if you have not had your fill of

0:30:46.360 --> 0:30:50.400
<v Speaker 1>medieval tech, I recommend you check that out because yeah,

0:30:50.520 --> 0:30:53.640
<v Speaker 1>the Castle's podcast. I'm sure we'll be really really interesting.

0:30:53.640 --> 0:30:55.840
<v Speaker 1>I haven't heard it yet because they recorded it about

0:30:55.880 --> 0:30:58.680
<v Speaker 1>an hour before we recorded this and I was not

0:30:58.720 --> 0:31:02.400
<v Speaker 1>in the room. So um, but hopefully in that that

0:31:02.600 --> 0:31:06.960
<v Speaker 1>that kind of fills that that need to hear stuff

0:31:07.000 --> 0:31:11.040
<v Speaker 1>about Renaissance fairs and and create the Society of Creative Anachronism.

0:31:11.120 --> 0:31:14.760
<v Speaker 1>That's s c A. Uh not really our field, but

0:31:14.840 --> 0:31:17.280
<v Speaker 1>we decided to try try and tackle it anyway, although

0:31:17.320 --> 0:31:20.160
<v Speaker 1>some of them have been spotted by the Google street

0:31:20.200 --> 0:31:23.280
<v Speaker 1>view cameras. That's true, that's true. Yeah, we could way

0:31:23.320 --> 0:31:26.480
<v Speaker 1>to rope that in. If any of you have any questions,

0:31:26.520 --> 0:31:30.000
<v Speaker 1>hopefully dealing with technology, you can shoot us an email.

0:31:30.200 --> 0:31:33.400
<v Speaker 1>That's tech stuff at how stuff works dot com and

0:31:33.400 --> 0:31:35.320
<v Speaker 1>you might think, well, gosh, is any of this on

0:31:35.360 --> 0:31:38.560
<v Speaker 1>the website? Actually yes, How Iron and Steel Work is

0:31:38.600 --> 0:31:42.840
<v Speaker 1>an excellent article uh CO written by Marshall Brain and

0:31:42.960 --> 0:31:46.040
<v Speaker 1>Robert Lamb. I recommend that it's a great article on

0:31:46.080 --> 0:31:47.480
<v Speaker 1>the site if you want to learn more about the

0:31:47.520 --> 0:31:50.560
<v Speaker 1>history of iron and steel. And we will talk to

0:31:50.560 --> 0:31:56.920
<v Speaker 1>you again really soon for more on this and thousands

0:31:56.920 --> 0:32:00.280
