WEBVTT - TechStuff Classic: Say My Name

0:00:04.120 --> 0:00:07.160
<v Speaker 1>Get in touch with technology with tech Stuff from how

0:00:07.200 --> 0:00:13.680
<v Speaker 1>stuff works dot com. Hey there, and welcome to tech Stuff.

0:00:13.720 --> 0:00:16.520
<v Speaker 1>I'm your host, Jonathan Strickland. I'm an executive producer with

0:00:16.520 --> 0:00:19.279
<v Speaker 1>how Stuff Works in love all things tech, and it's

0:00:19.280 --> 0:00:22.959
<v Speaker 1>time for another classic episode of tech Stuff, and this one,

0:00:23.520 --> 0:00:29.280
<v Speaker 1>Lauren Vogelbaum and I go over the contributions of Heisenberg.

0:00:29.600 --> 0:00:34.879
<v Speaker 1>What do you do? I'm not certain. Ah, that's a joke, no,

0:00:35.000 --> 0:00:39.040
<v Speaker 1>But seriously, we wanted to talk about Heisenberg. Heisenberg's work

0:00:39.520 --> 0:00:43.519
<v Speaker 1>in theoretical physics and how that made a huge impact

0:00:43.640 --> 0:00:47.200
<v Speaker 1>and continues to make a huge impact in technology. So

0:00:47.479 --> 0:00:51.839
<v Speaker 1>sit back, relax, and enjoy this classic episode of tech Stuff.

0:00:53.080 --> 0:00:57.120
<v Speaker 1>I'm just not sure about this topic. Heisenberg, right, okay,

0:00:57.120 --> 0:00:58.520
<v Speaker 1>wall I think I have some notes on him too,

0:00:58.520 --> 0:01:00.720
<v Speaker 1>are you? This is he was born on December five,

0:01:00.760 --> 0:01:05.280
<v Speaker 1>nineteen o one. Yes, that one, the physicist. Yes, the

0:01:05.319 --> 0:01:08.720
<v Speaker 1>famous theoretical physicist. All right, well, all right, maybe I

0:01:08.720 --> 0:01:12.280
<v Speaker 1>won't get a geek out about breaking bad, but that's fine.

0:01:12.319 --> 0:01:16.160
<v Speaker 1>We can talk about Vernon Heisenberg. I like that your

0:01:16.200 --> 0:01:18.440
<v Speaker 1>German pronunciation is better than the lady with the last

0:01:18.520 --> 0:01:24.319
<v Speaker 1>name vocal bomb. That's pretty that's pretty great. Um. So

0:01:24.800 --> 0:01:27.800
<v Speaker 1>born on December five, nineteen o one, in Verzberg. Uh

0:01:28.120 --> 0:01:32.440
<v Speaker 1>and yeah, Heisenberg has played an incredibly important role in

0:01:32.800 --> 0:01:38.080
<v Speaker 1>the establishment that that's the foundations of what is quantum mechanics. Right.

0:01:38.120 --> 0:01:41.440
<v Speaker 1>If you've heard of something something called the uncertainty principle,

0:01:41.560 --> 0:01:44.600
<v Speaker 1>that is a k A. Heisenberg's n certain new principle,

0:01:44.760 --> 0:01:47.360
<v Speaker 1>that that is, he is the operative Heisenberg. In this

0:01:49.440 --> 0:01:52.680
<v Speaker 1>we will explain what that uncertainty principle is in certain terms,

0:01:53.440 --> 0:01:55.880
<v Speaker 1>but that'll be towards the second half of the podcast.

0:01:55.880 --> 0:01:58.440
<v Speaker 1>First we wanted to kind of talk about who he was,

0:01:58.560 --> 0:02:02.440
<v Speaker 1>sort of his background. His father was an expert in

0:02:02.520 --> 0:02:07.600
<v Speaker 1>Middle and modern Greek languages. That's a Dr. August Heisenberg.

0:02:08.080 --> 0:02:13.600
<v Speaker 1>His mother was any Winklin. Winklin Winklin was w. Yes,

0:02:13.720 --> 0:02:17.960
<v Speaker 1>there's no W sound in German. It's um. Yeah, so vs,

0:02:18.040 --> 0:02:20.680
<v Speaker 1>r F S and w s or vs. That's easy

0:02:20.720 --> 0:02:24.560
<v Speaker 1>to remember, simple, all right, Yeah, so yeah, he he um.

0:02:24.639 --> 0:02:28.320
<v Speaker 1>It's funny because I understand that his his own background

0:02:28.520 --> 0:02:31.640
<v Speaker 1>in Greek, his father was an expert in Greek. His

0:02:31.680 --> 0:02:34.280
<v Speaker 1>own background in Greek meant that when they got to

0:02:34.320 --> 0:02:38.720
<v Speaker 1>the point where physicists were starting to name theoretical and

0:02:40.600 --> 0:02:43.160
<v Speaker 1>he would correct people's use of Greek, saying things like,

0:02:43.880 --> 0:02:46.240
<v Speaker 1>you cannot spell it this way because that's not how

0:02:46.280 --> 0:02:48.720
<v Speaker 1>it would be actually spelled if such a thing existed

0:02:48.720 --> 0:02:52.359
<v Speaker 1>in the Greek language. So so he was, um, you know,

0:02:52.560 --> 0:02:55.360
<v Speaker 1>helping us stay on the rails as far as the

0:02:55.440 --> 0:02:57.880
<v Speaker 1>use of Greek, right while he was growing up. When

0:02:57.880 --> 0:03:00.239
<v Speaker 1>he was twelve, that is when Neil's Bore present did

0:03:00.360 --> 0:03:04.320
<v Speaker 1>his general theory of of quantum existence. Yes, so Bore

0:03:05.040 --> 0:03:10.680
<v Speaker 1>would be incredibly important during Heisenberg's education. But Niels Bore

0:03:10.760 --> 0:03:13.520
<v Speaker 1>also known for making the Bore model of the atom.

0:03:13.960 --> 0:03:16.480
<v Speaker 1>So that was the model the atom that suggested that

0:03:16.480 --> 0:03:19.480
<v Speaker 1>you had a central nucleus and then electrons that were

0:03:19.600 --> 0:03:24.080
<v Speaker 1>orbiting nucleus. Yeah, so that's you know, anyone who's taken

0:03:24.120 --> 0:03:28.960
<v Speaker 1>any any class in chemistry or physics has seen the

0:03:28.960 --> 0:03:31.919
<v Speaker 1>Boor model. It's still one of those things that um

0:03:32.200 --> 0:03:35.800
<v Speaker 1>usually is. It's part of the history of the development

0:03:35.840 --> 0:03:39.160
<v Speaker 1>of particle physics and quantum mechanics. Right, we we know

0:03:39.200 --> 0:03:41.680
<v Speaker 1>now that it's a little bit um simplified. Yeah. In fact,

0:03:41.680 --> 0:03:44.120
<v Speaker 1>Heisenberg would go on, would be the one who right

0:03:44.200 --> 0:03:48.320
<v Speaker 1>exactly right. Uh, he was. While he was in high school,

0:03:48.320 --> 0:03:51.320
<v Speaker 1>there was a major event that played out across the

0:03:51.520 --> 0:03:55.600
<v Speaker 1>entire world and particularly in Europe. World War One. Yeah,

0:03:55.720 --> 0:03:59.320
<v Speaker 1>World War One happened between nineteen fourteen and nineteen eighteen.

0:04:00.040 --> 0:04:04.840
<v Speaker 1>Some of Heisenberg's academic contemporaries, or not even contemporaries, some

0:04:04.920 --> 0:04:08.040
<v Speaker 1>of his mentors had actually served in World War One

0:04:08.240 --> 0:04:11.720
<v Speaker 1>as various officers in the military, right right. Um, Heisenberg

0:04:11.760 --> 0:04:14.600
<v Speaker 1>himself had to leave school, leave high school to go

0:04:14.760 --> 0:04:18.880
<v Speaker 1>help harvest crops in Bavaria at the time. And um,

0:04:18.920 --> 0:04:20.800
<v Speaker 1>by by the time he got back after the war,

0:04:21.040 --> 0:04:24.039
<v Speaker 1>he was deeply involved in youth groups like the New

0:04:24.040 --> 0:04:28.240
<v Speaker 1>Boy Scouts that we're trying to rebuild the science and

0:04:28.400 --> 0:04:31.440
<v Speaker 1>artistic culture in Germany. Right, So keep in mind, like

0:04:31.480 --> 0:04:36.279
<v Speaker 1>at this time in Germany, things are really tumultuous. I mean,

0:04:36.680 --> 0:04:40.400
<v Speaker 1>World War One was already one of those events that

0:04:40.400 --> 0:04:44.760
<v Speaker 1>that played upon certain sentiments in Germany, and after the

0:04:44.800 --> 0:04:48.760
<v Speaker 1>war was concluded, that got even more messy because you

0:04:48.839 --> 0:04:52.520
<v Speaker 1>had the rest of the world, uh, you know, trying

0:04:52.560 --> 0:04:54.719
<v Speaker 1>to deal with this situation and make sure that it

0:04:54.760 --> 0:04:56.680
<v Speaker 1>could not happen again. I mean, this was one of

0:04:56.680 --> 0:05:00.200
<v Speaker 1>those wars that no one really expected whatever happened, because

0:05:00.200 --> 0:05:02.080
<v Speaker 1>the idea was that everyone would be building up their

0:05:02.160 --> 0:05:04.479
<v Speaker 1>armies to a point that anyone would be crazy to

0:05:04.520 --> 0:05:07.760
<v Speaker 1>attack anyone else. And as it turns out, humans are crazy, y'all.

0:05:08.120 --> 0:05:10.560
<v Speaker 1>So um, yeah, we it was. It was one of

0:05:10.600 --> 0:05:13.200
<v Speaker 1>those things where where as in an attempt to prevent

0:05:13.240 --> 0:05:15.719
<v Speaker 1>this from happening again, there were a lot of reparations

0:05:15.760 --> 0:05:19.600
<v Speaker 1>demanded against Germany. This in turn ended up fueling a

0:05:19.640 --> 0:05:24.920
<v Speaker 1>lot of resentment in Germany and would eventually give the

0:05:25.880 --> 0:05:29.599
<v Speaker 1>Nazi movement sort of the kind of foothold. Yeah, exactly,

0:05:29.600 --> 0:05:34.279
<v Speaker 1>it gave them that that that place to build some support,

0:05:34.360 --> 0:05:37.240
<v Speaker 1>because you had all these Germans who felt that uh,

0:05:37.360 --> 0:05:40.159
<v Speaker 1>that their lives had been ruined as a result of

0:05:40.320 --> 0:05:43.800
<v Speaker 1>the actions that followed World War One. Now that plays

0:05:43.800 --> 0:05:48.000
<v Speaker 1>a big role in Heisenberg's life because this is also

0:05:48.080 --> 0:05:52.920
<v Speaker 1>a time when physicists are making incredible discoveries. We are

0:05:53.000 --> 0:05:57.120
<v Speaker 1>learning more about the quantum world, that that atomic scale

0:05:57.160 --> 0:06:01.520
<v Speaker 1>world than ever before. The instruments that were being made

0:06:01.560 --> 0:06:04.200
<v Speaker 1>were becoming precise enough for us to look at things

0:06:04.240 --> 0:06:06.320
<v Speaker 1>on a level that we never could have seen before.

0:06:06.720 --> 0:06:11.840
<v Speaker 1>So there is a figurative explosion in physics at this time,

0:06:11.960 --> 0:06:15.600
<v Speaker 1>and a lot of and sometimes literal explosions. But a

0:06:15.600 --> 0:06:18.839
<v Speaker 1>lot of the physicists that were active at this time,

0:06:18.880 --> 0:06:22.799
<v Speaker 1>particularly in Germany, were of Jewish descent. Now, of course

0:06:22.880 --> 0:06:26.560
<v Speaker 1>that would cause play another important role once we talk

0:06:26.640 --> 0:06:29.159
<v Speaker 1>about the rise of the Nazi movement and the entry

0:06:29.200 --> 0:06:33.719
<v Speaker 1>into World War two. Obviously that's going to to really

0:06:33.720 --> 0:06:36.760
<v Speaker 1>shake things up. But before we get to that point,

0:06:36.760 --> 0:06:40.760
<v Speaker 1>we talk more a little about about Heisenberg's educational background.

0:06:41.440 --> 0:06:45.440
<v Speaker 1>Once World War One had concluded, he attended the Maximilian

0:06:45.520 --> 0:06:49.160
<v Speaker 1>School at Munich and then eventually the University of Munich.

0:06:49.560 --> 0:06:52.920
<v Speaker 1>He originally went to study math, but according to reports,

0:06:52.920 --> 0:06:55.599
<v Speaker 1>a professor wouldn't let him into an advanced seminar, and

0:06:55.600 --> 0:06:58.279
<v Speaker 1>that's when he switched to physics. And just imagine what

0:06:58.320 --> 0:07:01.479
<v Speaker 1>the world would be like without the I mean, quantum physics,

0:07:01.520 --> 0:07:05.720
<v Speaker 1>for example, might have a very different approach, particularly when

0:07:05.760 --> 0:07:08.080
<v Speaker 1>you start talking about people like Schrodinger, and we will

0:07:08.520 --> 0:07:12.400
<v Speaker 1>and maybe we'll even mention his cat so uh. He

0:07:12.560 --> 0:07:16.600
<v Speaker 1>at the university, he studied physics with professors like Arnold

0:07:16.680 --> 0:07:21.400
<v Speaker 1>Johannes Wilhelm Sommerfeld, who was a theoretical physicist. Uh he

0:07:21.840 --> 0:07:25.840
<v Speaker 1>was a physicist who would stay on teaching even during

0:07:25.840 --> 0:07:29.160
<v Speaker 1>World War Two, so he stayed in Germany and continued

0:07:29.200 --> 0:07:34.560
<v Speaker 1>to teach. He did get a little upset that the

0:07:34.840 --> 0:07:37.760
<v Speaker 1>more than a little upset that his departments were being

0:07:37.840 --> 0:07:42.200
<v Speaker 1>completely yet purged of anyone who had any sort of

0:07:42.280 --> 0:07:45.240
<v Speaker 1>Jewish background, whether they self identified as Jewish or if

0:07:45.240 --> 0:07:49.560
<v Speaker 1>they had maybe an ancestor the three generations back who

0:07:49.600 --> 0:07:52.840
<v Speaker 1>was Jewish. Sure. Also, according to some reports, the Nazis

0:07:52.840 --> 0:07:57.000
<v Speaker 1>considered the theoretical physics as a field to be Jewish. Yes, yes,

0:07:57.040 --> 0:08:00.720
<v Speaker 1>because there were there were so many Jewish thinkers who

0:08:00.720 --> 0:08:05.440
<v Speaker 1>were the leaders of theoretical physics that the Nazis looked

0:08:05.440 --> 0:08:08.920
<v Speaker 1>down upon the entire discipline as being something that was

0:08:09.000 --> 0:08:12.760
<v Speaker 1>impure and should be completely purged. And in fact, instead

0:08:12.800 --> 0:08:16.920
<v Speaker 1>they wanted to have Deutsche physique that's German physics as

0:08:16.960 --> 0:08:19.800
<v Speaker 1>a study as opposed to theoretical physics, so that would

0:08:19.800 --> 0:08:24.280
<v Speaker 1>also disrupt the advances that could have happened during that time.

0:08:24.680 --> 0:08:29.880
<v Speaker 1>Another professor was Wilhelm Karl Ferner Otto, Fritz Franvien. You're

0:08:29.920 --> 0:08:32.319
<v Speaker 1>just enjoying saying these names, aren't you. Wil Helm veen

0:08:32.400 --> 0:08:35.120
<v Speaker 1>Is usually how we we say that, but yes, you're

0:08:35.280 --> 0:08:37.559
<v Speaker 1>The answer to that question is yes, I love I

0:08:37.600 --> 0:08:40.680
<v Speaker 1>love saying German names. Uh. He was a physicist and

0:08:40.720 --> 0:08:44.840
<v Speaker 1>he focused on black body radiation and electromagnetics magnetism rather

0:08:45.360 --> 0:08:49.400
<v Speaker 1>and he passed away in so he died before World

0:08:49.440 --> 0:08:52.760
<v Speaker 1>War two began. He died before the Nazis had really

0:08:52.760 --> 0:08:57.480
<v Speaker 1>taken control of Germany. Um there was Alfred Pringsheim who

0:08:57.520 --> 0:09:00.240
<v Speaker 1>was a professor of mathematics and had Jewish roots. During

0:09:00.240 --> 0:09:03.840
<v Speaker 1>the Nazi regime, he would see his entire fortune taken

0:09:03.880 --> 0:09:07.959
<v Speaker 1>from him. Everything he had inherited a huge fortune and

0:09:08.160 --> 0:09:11.199
<v Speaker 1>everything he owned was taken by the Nazis. He was

0:09:11.240 --> 0:09:15.119
<v Speaker 1>eventually forced to change his name to Alfred Israel Prinsheim

0:09:15.200 --> 0:09:20.240
<v Speaker 1>because of his Jewish ancestry. One wonderfully racist, you know,

0:09:20.320 --> 0:09:22.959
<v Speaker 1>the Nazis were not known for being subtle with the

0:09:23.440 --> 0:09:27.240
<v Speaker 1>way that they treated any one of Jewish heritage. And

0:09:27.280 --> 0:09:31.440
<v Speaker 1>then a fourth professor was Arthur Rosenthal, who had a

0:09:31.440 --> 0:09:34.520
<v Speaker 1>focus on geometry as well as dynamical systems, also had

0:09:34.600 --> 0:09:37.440
<v Speaker 1>Jewish roots. He would be forced from his position in

0:09:37.559 --> 0:09:40.199
<v Speaker 1>nineteen thirty six by the Nazis and would eventually immigrate

0:09:40.240 --> 0:09:42.400
<v Speaker 1>to the United States and nineteen nine and taught at

0:09:42.400 --> 0:09:45.480
<v Speaker 1>the University of Michigan, which has come up a lot

0:09:45.480 --> 0:09:48.240
<v Speaker 1>in our conversations recently because that's where Sid went to.

0:09:49.200 --> 0:09:51.679
<v Speaker 1>But he taught the University of Michigan, then eventually taught

0:09:51.679 --> 0:09:53.800
<v Speaker 1>at the University of New Mexico and then later at

0:09:53.800 --> 0:09:58.640
<v Speaker 1>Purdue University. So these were the four professors who really

0:09:59.520 --> 0:10:03.840
<v Speaker 1>kind of sparked Heisenberg's fascination with physics and mathematics, and

0:10:04.000 --> 0:10:10.400
<v Speaker 1>this is founding in in those subjects exactly, So Somerfeld, Veen, Pringsheim,

0:10:10.559 --> 0:10:15.200
<v Speaker 1>and Rosenthal Uh. Then in nineteen two Heisenberg went to

0:10:15.480 --> 0:10:20.640
<v Speaker 1>Goodingen Goodingen as a University of Goodingen to study physics

0:10:20.679 --> 0:10:26.520
<v Speaker 1>under some more famous physicists, including Max Bourne, whose focus

0:10:26.559 --> 0:10:30.600
<v Speaker 1>was on quantum mechanics, particularly in statistical interpretation of the

0:10:30.640 --> 0:10:33.719
<v Speaker 1>wave functioned, which we will talk about again and a

0:10:33.760 --> 0:10:37.480
<v Speaker 1>little bit because Schrodinger was definitely a wave functioned guy.

0:10:37.600 --> 0:10:40.559
<v Speaker 1>As it turns out, Heisenberg was different. He did not

0:10:40.760 --> 0:10:43.679
<v Speaker 1>really look at the wave function of quantum physics. He

0:10:43.800 --> 0:10:45.720
<v Speaker 1>was looking at something else. And now I'll explain that

0:10:45.760 --> 0:10:49.720
<v Speaker 1>when we get there, because that's fun for me. Um.

0:10:49.800 --> 0:10:52.439
<v Speaker 1>The born Max Boorne was also the director of theoretical

0:10:52.480 --> 0:10:56.400
<v Speaker 1>physics at the university and was Jewish, so he immigrated

0:10:56.440 --> 0:10:58.560
<v Speaker 1>to the United Kingdom when the Nazis came into power

0:10:58.640 --> 0:11:03.320
<v Speaker 1>in Germany and continued to research particle physics, well well

0:11:03.360 --> 0:11:06.600
<v Speaker 1>not quite particle physics, quantum physics, and theoretical physics, as

0:11:06.600 --> 0:11:11.080
<v Speaker 1>well as teaching in the UK. Then you had James Frank,

0:11:11.280 --> 0:11:15.480
<v Speaker 1>who was a physicistant, studied atomic and subatomic collisions, particularly

0:11:15.600 --> 0:11:19.840
<v Speaker 1>electrons colliding with adams, and also was of Jewish heritage.

0:11:19.960 --> 0:11:22.079
<v Speaker 1>So he would leave Germany in nineteen thirty three for

0:11:22.120 --> 0:11:25.560
<v Speaker 1>the United States and would later participate in what was

0:11:25.800 --> 0:11:28.959
<v Speaker 1>known as the Manhattan Project. We could do a full

0:11:29.000 --> 0:11:32.920
<v Speaker 1>episode on the Manhattan Project that in fact. Yeah, it's

0:11:32.960 --> 0:11:38.880
<v Speaker 1>an amazing story. Um. And here's another great story with

0:11:39.200 --> 0:11:41.480
<v Speaker 1>James Frank. So he won the Nobel Prize in n

0:11:42.400 --> 0:11:46.040
<v Speaker 1>for physics. He left the gold medal, the Nobel Prize

0:11:46.040 --> 0:11:49.520
<v Speaker 1>medal back in Germany when he left to essentially flee

0:11:49.600 --> 0:11:53.120
<v Speaker 1>to the United States. Um. There was another physicist named

0:11:53.200 --> 0:11:56.440
<v Speaker 1>George de Heavasy. And I know I'm saying that name wrong,

0:11:56.440 --> 0:11:59.160
<v Speaker 1>so I greatly apologize. But for once, we're talking about

0:11:59.200 --> 0:12:01.079
<v Speaker 1>someone who's not German, so I can't say his name,

0:12:01.840 --> 0:12:05.839
<v Speaker 1>but he he in order to protect this gold medal

0:12:06.000 --> 0:12:09.080
<v Speaker 1>from being taken by the Nazis and melted down, he

0:12:09.200 --> 0:12:12.880
<v Speaker 1>dissolved the metal and acid and then put the solution

0:12:13.040 --> 0:12:15.760
<v Speaker 1>on a shelf, so it's a solution with dissolved gold

0:12:15.840 --> 0:12:19.160
<v Speaker 1>on the shelf. World War two is over, he goes back,

0:12:19.360 --> 0:12:22.600
<v Speaker 1>the solution is still on the shelf. He then precipitates

0:12:22.640 --> 0:12:25.040
<v Speaker 1>that solution, precipitating the gold out of the acid, and

0:12:25.160 --> 0:12:27.640
<v Speaker 1>he used the gold to melt it back into the

0:12:27.679 --> 0:12:30.760
<v Speaker 1>metal and meant a new and meant a new metal

0:12:31.040 --> 0:12:34.839
<v Speaker 1>so that they can give it uh back to James Frank.

0:12:35.240 --> 0:12:37.839
<v Speaker 1>So that I thought was a really cool story. Then

0:12:37.880 --> 0:12:41.839
<v Speaker 1>there's another professor he studied under was David Hilbert was

0:12:41.880 --> 0:12:45.120
<v Speaker 1>a mathematician who focused on geometry and functional analysis who

0:12:45.160 --> 0:12:48.640
<v Speaker 1>retired in n so he lived to see the Nazis

0:12:48.720 --> 0:12:52.839
<v Speaker 1>purge Germany of Jewish mathematicians and physicists, and was later

0:12:52.880 --> 0:12:55.760
<v Speaker 1>asked at a state dinner. He was actually asked a

0:12:55.840 --> 0:12:58.480
<v Speaker 1>question about what was the state of mathematics after it

0:12:58.480 --> 0:13:01.880
<v Speaker 1>had been quote unquote free of Jewish influence, and his

0:13:01.920 --> 0:13:05.360
<v Speaker 1>response was, there's no study of mathematics anymore. He was

0:13:05.440 --> 0:13:09.600
<v Speaker 1>essentially saying that the actions of the Nazis had effectively

0:13:10.840 --> 0:13:15.320
<v Speaker 1>into the entire field because they had they had removed

0:13:15.480 --> 0:13:18.720
<v Speaker 1>or or had caused to flee all of the leading

0:13:18.760 --> 0:13:23.280
<v Speaker 1>thinkers and instead, including like Einstein. So they were turning

0:13:23.360 --> 0:13:27.160
<v Speaker 1>mathematics and science into a political thing, and by doing that,

0:13:27.480 --> 0:13:29.360
<v Speaker 1>they were saying that these other things that did not

0:13:29.440 --> 0:13:33.000
<v Speaker 1>fit that political regime as invalid. And that's not the

0:13:33.000 --> 0:13:36.640
<v Speaker 1>way science works, not the way mathematics works, but that's

0:13:36.640 --> 0:13:39.000
<v Speaker 1>how we're demanding it. It can be a very effective

0:13:39.040 --> 0:13:42.240
<v Speaker 1>means of controlling a population by controlling their education. Sure,

0:13:42.360 --> 0:13:47.120
<v Speaker 1>but also it also ends up meaning that you really you,

0:13:47.120 --> 0:13:50.719
<v Speaker 1>you just throw a huge monkey wrench into any kind

0:13:50.760 --> 0:13:54.880
<v Speaker 1>of advancement in those fields. So before World War two,

0:13:55.160 --> 0:13:57.040
<v Speaker 1>this is this is all happening before World War two,

0:13:57.040 --> 0:14:01.640
<v Speaker 1>and Heisenberg is studying under these different professors, so during

0:14:01.679 --> 0:14:05.400
<v Speaker 1>these years he has the ability to really pursue his

0:14:05.480 --> 0:14:10.640
<v Speaker 1>interests in theoretical physics and mathematics. So, uh, this was

0:14:10.679 --> 0:14:13.280
<v Speaker 1>on the in the nineteen twenties, and so it was

0:14:13.320 --> 0:14:16.439
<v Speaker 1>before even the Third Wreck was coming into power at all, right, Right,

0:14:16.480 --> 0:14:18.760
<v Speaker 1>So that these are in the years between World War

0:14:18.840 --> 0:14:22.240
<v Speaker 1>One and the Nazis rise to power. So during those years,

0:14:22.240 --> 0:14:25.240
<v Speaker 1>that's when Heisenberg was studying. And while many of his

0:14:25.360 --> 0:14:28.400
<v Speaker 1>professors would end up having to flee or would be

0:14:28.440 --> 0:14:31.400
<v Speaker 1>removed from their jobs, at this time none of that

0:14:31.520 --> 0:14:34.960
<v Speaker 1>was necessarily evident that that was going to happen, So

0:14:35.360 --> 0:14:38.000
<v Speaker 1>he spent his time really talking with some of the

0:14:38.120 --> 0:14:40.760
<v Speaker 1>leading thinkers of the day when it comes to theoretical

0:14:40.760 --> 0:14:44.720
<v Speaker 1>physics and mathematics, right um so Ine he earned his

0:14:44.800 --> 0:14:47.320
<v Speaker 1>PhD from the University of Munich and um went to

0:14:47.320 --> 0:14:50.200
<v Speaker 1>become an assistant to his old professor Maxi Born at

0:14:50.240 --> 0:14:55.240
<v Speaker 1>the University of getting In and so in four he

0:14:55.360 --> 0:14:58.360
<v Speaker 1>would go to the University of Copenhagen and begin work

0:14:58.400 --> 0:15:04.080
<v Speaker 1>with Niels Henrik David Bore, who was Danish, not German,

0:15:04.520 --> 0:15:07.640
<v Speaker 1>but a Danish physicist and uh and of course he

0:15:07.880 --> 0:15:11.120
<v Speaker 1>was really interested in atomic radiation and atomic structure, and

0:15:11.160 --> 0:15:13.560
<v Speaker 1>we talked about the Boor model of the atom earlier

0:15:13.560 --> 0:15:18.880
<v Speaker 1>in the podcast um so. In nineteen six Heisenberg would

0:15:18.880 --> 0:15:20.960
<v Speaker 1>go to the University of Copenhagen for about a year

0:15:20.960 --> 0:15:23.440
<v Speaker 1>and then leave. But in ninety six there was a

0:15:24.520 --> 0:15:27.600
<v Speaker 1>position opening opening up at the University of Copenhagen for

0:15:27.680 --> 0:15:32.720
<v Speaker 1>a lecturer in theoretical physics. So Boor recommended Heisenberg, thinking

0:15:32.720 --> 0:15:36.200
<v Speaker 1>that Heisenberg was an up and coming leader in this space,

0:15:36.560 --> 0:15:39.680
<v Speaker 1>and so Heisenberg became the lecturer and theoretical physics at

0:15:39.680 --> 0:15:44.560
<v Speaker 1>the University of Copenhagen. Bore himself would be at Copenhagen

0:15:44.640 --> 0:15:47.080
<v Speaker 1>for quite some time until nineteen forty three, where he

0:15:47.120 --> 0:15:52.440
<v Speaker 1>would eventually flee to Sweden to escape the Nazis. Nineteen five,

0:15:53.000 --> 0:15:57.320
<v Speaker 1>that's when Heisenberg publishes his theory of quantum mechanics. So

0:15:57.400 --> 0:16:00.160
<v Speaker 1>he was of the ripe old age of twin d

0:16:00.400 --> 0:16:05.600
<v Speaker 1>three years old, twenty three years old, and he is uh,

0:16:05.600 --> 0:16:10.880
<v Speaker 1>he is he is presenting a completely um well, he's

0:16:10.920 --> 0:16:14.800
<v Speaker 1>presenting his own, his own perspective on what quantum mechanics

0:16:14.800 --> 0:16:18.080
<v Speaker 1>actually is. As we'll see, that ends up getting kind

0:16:18.080 --> 0:16:23.320
<v Speaker 1>of assimilated into a unified view by looking at some

0:16:23.320 --> 0:16:26.800
<v Speaker 1>some other theories that Heisenberg did not necessarily agree with

0:16:26.880 --> 0:16:29.480
<v Speaker 1>at the time. Nope, not so much at all. As

0:16:29.480 --> 0:16:33.080
<v Speaker 1>it turns out, physicists, like any other type of human being,

0:16:33.360 --> 0:16:38.280
<v Speaker 1>can occasionally get very married to specific ideas and maybe

0:16:38.320 --> 0:16:41.240
<v Speaker 1>a little bit snarky. Yeah, there's some there's some great

0:16:41.320 --> 0:16:44.680
<v Speaker 1>quotes that will be reading. Yeah, but yeah, it turns

0:16:44.680 --> 0:16:49.920
<v Speaker 1>out that not everybody agreed on the behavior of particles

0:16:50.000 --> 0:16:52.320
<v Speaker 1>at that level because they were first of all, there

0:16:52.400 --> 0:16:55.120
<v Speaker 1>was no way to really directly observe them, so it's

0:16:55.160 --> 0:16:59.160
<v Speaker 1>all hypothetical, and it was mostly things like your equations

0:16:59.200 --> 0:17:02.400
<v Speaker 1>are are not as easy to understand my equations, therefore

0:17:02.440 --> 0:17:05.000
<v Speaker 1>my equations are better. That kind of thing. In fact,

0:17:05.040 --> 0:17:09.280
<v Speaker 1>that really is one of the arguments. So in n seven,

0:17:09.320 --> 0:17:12.520
<v Speaker 1>at the age of twenty six, you know, he's he's

0:17:12.560 --> 0:17:16.680
<v Speaker 1>definitely hitting that that middle age there for physicists. Twenty

0:17:16.720 --> 0:17:20.200
<v Speaker 1>six years old, he becomes the professor of theoretical physics

0:17:20.200 --> 0:17:22.359
<v Speaker 1>at the University of Leipsig and this made him the

0:17:22.560 --> 0:17:25.640
<v Speaker 1>youngest full professor in Germany at the time. Yeah, so

0:17:26.119 --> 0:17:29.280
<v Speaker 1>he was certainly making a name for himself in the

0:17:29.400 --> 0:17:33.320
<v Speaker 1>in the academic world. In nineteen nine he goes on

0:17:33.359 --> 0:17:37.280
<v Speaker 1>a lecture tour of the United States and Japan and India,

0:17:38.240 --> 0:17:40.639
<v Speaker 1>uh and in nineteen thirty two he received the Nobel

0:17:40.680 --> 0:17:43.760
<v Speaker 1>Prize in Physics for his discovery of the allotropic forms

0:17:43.760 --> 0:17:47.560
<v Speaker 1>of hydrogen. It was is for from that paper that

0:17:47.680 --> 0:17:51.119
<v Speaker 1>he had published about quantum mechanics. Out of that, one

0:17:51.119 --> 0:17:54.880
<v Speaker 1>of the applications was this discovery. Right. So, in case

0:17:54.920 --> 0:17:57.679
<v Speaker 1>you're wondering what the heck is an allotrope, it's a

0:17:57.680 --> 0:18:01.159
<v Speaker 1>different structural modification of an element. So let's take carbon.

0:18:01.600 --> 0:18:04.760
<v Speaker 1>Carbon is a great example. When you have a certain

0:18:04.760 --> 0:18:09.000
<v Speaker 1>structure of carbon, it forms graphite. Different structure of carbon

0:18:09.080 --> 0:18:12.760
<v Speaker 1>forms diamond too, slightly different substances. Yeah, these these different

0:18:13.320 --> 0:18:17.560
<v Speaker 1>these different manifestations of the same element. I mean, it's

0:18:17.720 --> 0:18:19.639
<v Speaker 1>it's the exact same element, it's just the way that

0:18:19.680 --> 0:18:24.000
<v Speaker 1>it's been or the way that it arranges itself determines

0:18:24.080 --> 0:18:27.600
<v Speaker 1>its qualities. And graphite and diamond are like nine day

0:18:27.720 --> 0:18:31.480
<v Speaker 1>they're incredibly different. So that's what an allotrope is is

0:18:31.520 --> 0:18:36.000
<v Speaker 1>these different manifestations of an element that have very different qualities.

0:18:36.600 --> 0:18:41.240
<v Speaker 1>With the case of hydrogen, we're talking about ortho hydrogen

0:18:41.280 --> 0:18:45.320
<v Speaker 1>and parahydrogen. Don't ask me what that actually means, because

0:18:45.920 --> 0:18:49.000
<v Speaker 1>I'm not a physicist or a chemist, so I am

0:18:49.040 --> 0:18:51.600
<v Speaker 1>incapable of answering me neither. I am. I'm at a

0:18:51.640 --> 0:18:54.080
<v Speaker 1>loss there, but I do know that In ninety seven,

0:18:54.280 --> 0:18:57.439
<v Speaker 1>Heisenberg married Elizabeth Schumacher, who he would go on to

0:18:57.440 --> 0:19:00.440
<v Speaker 1>have seven children with over the course of their marriage. Wow.

0:19:00.760 --> 0:19:04.159
<v Speaker 1>Now this is also the time when we're starting to

0:19:04.200 --> 0:19:06.720
<v Speaker 1>see the Nazis come into power in World War Two

0:19:06.800 --> 0:19:10.159
<v Speaker 1>is beginning, uh, and this was this becomes a pretty

0:19:10.720 --> 0:19:15.560
<v Speaker 1>muddy area of Heisenberg's life because it's hard to know

0:19:15.840 --> 0:19:19.679
<v Speaker 1>which historical records are the most accurate. Right, There's there's

0:19:19.680 --> 0:19:22.919
<v Speaker 1>a lot of contention within the historical community about um

0:19:22.960 --> 0:19:28.720
<v Speaker 1>what exactly Heisenberg's personal views and u and roles were

0:19:29.040 --> 0:19:31.840
<v Speaker 1>in In all of this, he had become the target

0:19:31.920 --> 0:19:39.240
<v Speaker 1>of of Johannes Stark. Na, I'm just er apologize our English.

0:19:39.280 --> 0:19:42.680
<v Speaker 1>Our English pronunciation in German pronunciation are different and and

0:19:42.840 --> 0:19:45.760
<v Speaker 1>and to be fair, the vocal downside of my family

0:19:45.880 --> 0:19:50.040
<v Speaker 1>is is really more like Polish Russian. So Johannes Stark

0:19:50.280 --> 0:19:53.080
<v Speaker 1>was also a physicist, but he was and he was

0:19:53.119 --> 0:19:56.560
<v Speaker 1>a physicist in fact, who in his UH in the

0:19:56.600 --> 0:19:59.920
<v Speaker 1>twenties had published a paper by Einstein. He had act

0:20:00.320 --> 0:20:03.840
<v Speaker 1>um Uh solicited Einstein to write a paper for the

0:20:03.880 --> 0:20:07.520
<v Speaker 1>publication that he was editing, and it was a publication

0:20:07.560 --> 0:20:12.680
<v Speaker 1>that would eventually lead Einstein to ruminate upon the general

0:20:12.720 --> 0:20:15.600
<v Speaker 1>theory of relativity. It was sort of a kind of

0:20:15.600 --> 0:20:19.359
<v Speaker 1>a precursor to his general theory, which meant that in

0:20:19.400 --> 0:20:22.959
<v Speaker 1>a way, Johannes Stark was very much part of what

0:20:23.119 --> 0:20:26.800
<v Speaker 1>made Einstein a worldwide phenomenon. Now, the reason why I

0:20:26.840 --> 0:20:31.120
<v Speaker 1>say that's really interesting, or perhaps he might even say ironic,

0:20:31.640 --> 0:20:35.480
<v Speaker 1>is that Johannes Stark would align himself with the Nazi regime.

0:20:35.920 --> 0:20:40.320
<v Speaker 1>He wanted essentially to be the fewer of physics, which

0:20:40.400 --> 0:20:43.320
<v Speaker 1>is that's I mean, that's exactly the way I saw

0:20:43.320 --> 0:20:45.639
<v Speaker 1>it worded when I was reading the biography, which is

0:20:45.720 --> 0:20:50.280
<v Speaker 1>kind of terrifying. But he he also aligned himself with

0:20:50.320 --> 0:20:54.560
<v Speaker 1>the Deutsche Physics movement, the the German physics movement, and

0:20:54.880 --> 0:20:59.800
<v Speaker 1>he said that because Heisenberg continued to teach Einstein's theories

0:20:59.840 --> 0:21:02.199
<v Speaker 1>and the classroom in Einstein's theories, of course we're not

0:21:02.280 --> 0:21:06.639
<v Speaker 1>part of this Deutsche physics, uh movement, that he was

0:21:06.760 --> 0:21:10.200
<v Speaker 1>what what Stark would call a white Jew or an

0:21:10.240 --> 0:21:13.560
<v Speaker 1>arian Jew, someone who is not Jewish by heritage, but

0:21:13.720 --> 0:21:17.160
<v Speaker 1>is by association, because he continues to teach these thoughts

0:21:17.760 --> 0:21:22.760
<v Speaker 1>that Jewish mathematicians and physicists had come up with, so

0:21:22.800 --> 0:21:27.320
<v Speaker 1>that somehow that meant that he was a traitor. Yes, so,

0:21:28.119 --> 0:21:32.240
<v Speaker 1>um So Stark was very much opposed to Heisenberg and

0:21:32.240 --> 0:21:35.280
<v Speaker 1>didn't feel that Heisenberg should should have any sort of

0:21:35.320 --> 0:21:39.040
<v Speaker 1>position of authority. That did not stop Heisenberg from having

0:21:39.080 --> 0:21:44.080
<v Speaker 1>that position. He was obviously very important to the university

0:21:44.119 --> 0:21:46.880
<v Speaker 1>and was one of the few protected. Of course, part

0:21:46.920 --> 0:21:48.640
<v Speaker 1>of it was that he did not actually have any

0:21:48.720 --> 0:21:52.040
<v Speaker 1>Jewish ancestry that anyone could determine, so that kept him

0:21:52.119 --> 0:21:56.320
<v Speaker 1>somewhat safe, right sure, um you know, there's part of

0:21:56.320 --> 0:21:59.119
<v Speaker 1>the debate about Heisenberg is whether or not he um

0:21:59.200 --> 0:22:04.440
<v Speaker 1>he stayed in order to uh to help preserve Germany's

0:22:04.440 --> 0:22:08.159
<v Speaker 1>scientific and cultural communities, or whether he was actually working

0:22:08.160 --> 0:22:11.199
<v Speaker 1>for the Nazi Party. Um he he was made the

0:22:11.240 --> 0:22:14.960
<v Speaker 1>director of the German Adam bomb project and spent about

0:22:15.000 --> 0:22:19.159
<v Speaker 1>five years working on that, supposedly, during which another portion

0:22:19.200 --> 0:22:21.600
<v Speaker 1>of the debate is whether he was working towards a

0:22:21.680 --> 0:22:25.480
<v Speaker 1>nuclear reactor or nuclear weapons, and no one is really

0:22:25.640 --> 0:22:28.560
<v Speaker 1>entirely sure. Supposedly he gave a report to Nazi official

0:22:28.640 --> 0:22:32.040
<v Speaker 1>Albert spear Um that as of one or so, it

0:22:32.080 --> 0:22:34.280
<v Speaker 1>would take three or four years for them to build

0:22:34.320 --> 0:22:37.440
<v Speaker 1>a nuclear weapon and that that is part of why

0:22:37.560 --> 0:22:40.240
<v Speaker 1>the Nazi Party said, I'll forget this nuclear weapon thing,

0:22:40.320 --> 0:22:47.240
<v Speaker 1>let's go with nuclear reactors to help drive Sure, um

0:22:47.440 --> 0:22:52.880
<v Speaker 1>and uh so, but but you know, that's that's There's

0:22:52.920 --> 0:22:56.760
<v Speaker 1>been other research. Um. For for example, one Paul Lawrence

0:22:56.920 --> 0:22:59.880
<v Speaker 1>Rose wrote an entire book called Heisenberg and the Nazi

0:23:00.000 --> 0:23:04.720
<v Speaker 1>Stomic Bomb Project that stated that, uh, Heisenberg wasn't being

0:23:04.720 --> 0:23:07.080
<v Speaker 1>evasive to the Nazi Party, that rather, he was being

0:23:07.520 --> 0:23:11.000
<v Speaker 1>truthful due to a basic misunderstanding of the way that

0:23:11.119 --> 0:23:14.000
<v Speaker 1>nuclear fission worked, and that by the time he figured

0:23:14.040 --> 0:23:17.080
<v Speaker 1>it out, it was when the war was already winding

0:23:17.119 --> 0:23:20.119
<v Speaker 1>down and he started to hear about the atrocities that

0:23:20.119 --> 0:23:24.959
<v Speaker 1>the Nazi Party had committed and kind of reactively recreated

0:23:25.080 --> 0:23:28.359
<v Speaker 1>this image of himself as as having been an anti

0:23:28.440 --> 0:23:30.800
<v Speaker 1>Nazi the entire time. And that's the thing is that

0:23:30.880 --> 0:23:33.040
<v Speaker 1>it's it's impossible for us to say one way or

0:23:33.080 --> 0:23:36.560
<v Speaker 1>the other because there are conflicting reports and and really

0:23:36.720 --> 0:23:40.280
<v Speaker 1>it's you know, it's just it's a it's a difficult thing. Again.

0:23:40.400 --> 0:23:43.800
<v Speaker 1>Once again, we take our our our podcasting hats off

0:23:43.800 --> 0:23:46.280
<v Speaker 1>to our sister podcast Stuff you missed in history class

0:23:46.280 --> 0:23:48.080
<v Speaker 1>that deals with this kind of stuff all the time.

0:23:48.160 --> 0:23:51.040
<v Speaker 1>Oh sure, and and especially you know, everything surrounding the

0:23:51.119 --> 0:23:53.720
<v Speaker 1>Nazi Party is incredibly sticky. Um. You know, some some

0:23:53.800 --> 0:23:56.520
<v Speaker 1>of my favorite favorite stories about that time or stuff

0:23:56.560 --> 0:23:59.240
<v Speaker 1>like like like like Lenie Reefinstahl, who was one of

0:23:59.320 --> 0:24:04.439
<v Speaker 1>the who was the propagandist or a documentary filmmaker for

0:24:04.480 --> 0:24:06.920
<v Speaker 1>the Nazi Party, And I mean she she took tea

0:24:06.960 --> 0:24:10.800
<v Speaker 1>with Hitler frequently and has claimed forever that she never

0:24:10.880 --> 0:24:13.600
<v Speaker 1>knew about the atrocities that were going on. And so

0:24:13.960 --> 0:24:16.119
<v Speaker 1>it's it's it's one of those things like who do

0:24:16.160 --> 0:24:20.119
<v Speaker 1>you believe? Yeah, and uh yeah, getting back into into

0:24:20.200 --> 0:24:23.840
<v Speaker 1>the what Heisenberg was going through at this time. So

0:24:24.800 --> 0:24:27.080
<v Speaker 1>there is there's an argument to be made that he

0:24:27.200 --> 0:24:32.280
<v Speaker 1>was trying to preserve the scientific community in Germany as

0:24:32.320 --> 0:24:34.440
<v Speaker 1>best he could, because there were others who were also

0:24:34.480 --> 0:24:37.720
<v Speaker 1>trying to do that. Max Planck, for example, was also

0:24:37.840 --> 0:24:42.040
<v Speaker 1>trying to um to do that. Although Plank had hoped

0:24:42.560 --> 0:24:45.479
<v Speaker 1>that the the rise of the Nazis was just a

0:24:45.600 --> 0:24:49.199
<v Speaker 1>temporary kind of kerfuffle and that it wasn't going to

0:24:49.480 --> 0:24:54.360
<v Speaker 1>balloon into this incredible conflict that would span the entire globe,

0:24:55.359 --> 0:24:58.080
<v Speaker 1>he just had no he had no concept of that

0:24:58.160 --> 0:25:01.439
<v Speaker 1>actually happening, so he had I had to stay and

0:25:01.560 --> 0:25:06.359
<v Speaker 1>to try and keep the German departments of mathematics and

0:25:06.359 --> 0:25:09.640
<v Speaker 1>physics as intact as possible. So it could be that

0:25:09.640 --> 0:25:13.320
<v Speaker 1>that's the case, We honestly don't know. In ninety one,

0:25:13.760 --> 0:25:16.399
<v Speaker 1>Heisenberg becomes the professor of physics at the University of

0:25:16.400 --> 0:25:20.320
<v Speaker 1>Berlin and the director of the kaiserville Helm Institute for Physics,

0:25:21.080 --> 0:25:24.760
<v Speaker 1>and in nineteen forty five Heisenberg is taken prisoner by

0:25:24.800 --> 0:25:28.920
<v Speaker 1>American troops and is sent to England. UH. He's freed

0:25:28.960 --> 0:25:31.800
<v Speaker 1>in nineteen forty six and returns to Germany and helps

0:25:31.880 --> 0:25:35.760
<v Speaker 1>rebuild the Institute for Physics at Guttingen and then UH

0:25:35.880 --> 0:25:39.200
<v Speaker 1>that eventually becomes the Max Planck Institute for Physics, which

0:25:39.200 --> 0:25:43.800
<v Speaker 1>would eventually relocate, and I believe I believe Heisenberg personally

0:25:43.840 --> 0:25:48.600
<v Speaker 1>renamed the institute them on Max Plunk. And he would

0:25:48.640 --> 0:25:51.959
<v Speaker 1>continue to travel and give lectures about his work, in

0:25:52.000 --> 0:25:55.440
<v Speaker 1>fact doing so almost right up to when he died.

0:25:55.480 --> 0:25:58.080
<v Speaker 1>He died in on February one, nineteen seventy six, after

0:25:58.119 --> 0:26:02.320
<v Speaker 1>developing cancer, so he was very much active in the

0:26:02.359 --> 0:26:06.560
<v Speaker 1>world of lectures and academia. Well after the end of

0:26:06.600 --> 0:26:08.800
<v Speaker 1>World War Two. Yeah, towards the end of his life

0:26:08.840 --> 0:26:13.119
<v Speaker 1>he became interested in plasma physics and a thermonuclear processes.

0:26:13.640 --> 0:26:17.080
<v Speaker 1>So see, it's uh, you know, it's certainly one of

0:26:17.080 --> 0:26:20.280
<v Speaker 1>those interesting timelines. And in a moment, we're going to

0:26:20.359 --> 0:26:23.680
<v Speaker 1>really dive into what his contributions were in the field

0:26:23.720 --> 0:26:27.439
<v Speaker 1>of quantum mechanics and give a full explanation or as

0:26:27.600 --> 0:26:30.199
<v Speaker 1>as full as we possibly can make it of what

0:26:30.359 --> 0:26:32.880
<v Speaker 1>the uncertainty principle is all about, as well as why

0:26:32.880 --> 0:26:36.520
<v Speaker 1>it's important in technology, because yes, this does have to

0:26:36.560 --> 0:26:38.600
<v Speaker 1>do with tech. It's just going to take us a

0:26:38.600 --> 0:26:41.120
<v Speaker 1>while to get there. But before we jump into that,

0:26:41.280 --> 0:26:51.720
<v Speaker 1>let's take a quick break to thank our sponsor. Alright,

0:26:51.800 --> 0:26:56.359
<v Speaker 1>So now it's time to dive into quantum mechanics. I

0:26:56.440 --> 0:27:00.200
<v Speaker 1>gotta tell you, I'm not really certain about this. I'm

0:27:00.200 --> 0:27:05.200
<v Speaker 1>just gonna keep making that joke excellent until it's funny. Um. So, yeah,

0:27:05.240 --> 0:27:07.960
<v Speaker 1>he was. Heisenberg had worked in theoretical physics and quantum

0:27:07.960 --> 0:27:11.080
<v Speaker 1>mechanics during the early early days of the discipline, and

0:27:11.160 --> 0:27:16.240
<v Speaker 1>he was particularly interested in studying the radiation from an atom.

0:27:16.280 --> 0:27:18.960
<v Speaker 1>But here's the thing that he was also interested in

0:27:19.000 --> 0:27:22.520
<v Speaker 1>seeing what was actually observable, you know, really look at

0:27:22.520 --> 0:27:24.680
<v Speaker 1>the atom and see what you could actually see it

0:27:24.680 --> 0:27:29.679
<v Speaker 1>because we had all these hypothetical particles in these theoretical particles,

0:27:29.720 --> 0:27:33.240
<v Speaker 1>things that that should exist based upon the math involved.

0:27:33.640 --> 0:27:35.840
<v Speaker 1>But but but the science at the time was based

0:27:35.880 --> 0:27:39.800
<v Speaker 1>on on bombarding these these tiny, tiny, tiny sub atomic

0:27:39.800 --> 0:27:42.640
<v Speaker 1>particles with um with things like gamma radiation and then

0:27:42.960 --> 0:27:46.240
<v Speaker 1>observing what we could observe, right, And so he began

0:27:46.320 --> 0:27:49.359
<v Speaker 1>to differentiate between what you could observe and what you

0:27:49.400 --> 0:27:51.600
<v Speaker 1>could not, and then he started to notice things. He

0:27:51.600 --> 0:27:54.679
<v Speaker 1>said that, you know, we can't really always assign a

0:27:54.760 --> 0:27:59.440
<v Speaker 1>position in space to a specific electron at any given time,

0:27:59.600 --> 0:28:03.560
<v Speaker 1>and we can't follow electrons around their orbits. It's it's

0:28:03.600 --> 0:28:06.680
<v Speaker 1>not like a planetary orbit that we can watch continuously, right,

0:28:06.680 --> 0:28:09.919
<v Speaker 1>It's more like there's an area that an electron could

0:28:10.000 --> 0:28:13.080
<v Speaker 1>be in, as opposed to we can specifically point out

0:28:13.080 --> 0:28:15.200
<v Speaker 1>that this is where the electron is at any given moment,

0:28:15.280 --> 0:28:18.560
<v Speaker 1>or this is the direction it is traveling at any

0:28:18.600 --> 0:28:21.760
<v Speaker 1>given moment. And this would start to plant the seed

0:28:21.840 --> 0:28:26.760
<v Speaker 1>in his mind for the uncertainty principle. So first he

0:28:26.800 --> 0:28:29.879
<v Speaker 1>said that, you know, bores postulation that the the the

0:28:30.000 --> 0:28:32.920
<v Speaker 1>orbits of electrons are around the nucleus was more or

0:28:33.000 --> 0:28:36.320
<v Speaker 1>less correct. You couldn't actually be certain of what those

0:28:36.440 --> 0:28:41.760
<v Speaker 1>orbits were because the unobservable nature of these. Yeah, there's

0:28:41.800 --> 0:28:44.720
<v Speaker 1>just no way to assign a figure to this. You

0:28:44.720 --> 0:28:48.760
<v Speaker 1>can't say the electron is in uh, this particular quadrant

0:28:48.920 --> 0:28:53.440
<v Speaker 1>around the nucleus um and you couldn't talk about really

0:28:53.480 --> 0:28:56.600
<v Speaker 1>the electron's velocity either. Velocity, by the way, is speed

0:28:56.600 --> 0:29:00.120
<v Speaker 1>plus direction, right, And so he started to say that

0:29:00.160 --> 0:29:03.760
<v Speaker 1>instead of using UM classic numbers, the kinds of numbers

0:29:03.760 --> 0:29:08.400
<v Speaker 1>that we would use to describe human scale physics, that

0:29:08.400 --> 0:29:11.720
<v Speaker 1>that we needed to use UM matrices. Yeah, and a

0:29:11.800 --> 0:29:16.880
<v Speaker 1>matrix is essentially an abstract mathematical structure. So this was

0:29:17.000 --> 0:29:20.760
<v Speaker 1>almost like talking about probabilities. It's it's kind of fuzzy,

0:29:20.920 --> 0:29:24.440
<v Speaker 1>it's not specific, it's not precise. And in fact, that

0:29:24.480 --> 0:29:28.560
<v Speaker 1>was Heisenberg's argument, was that precision is something that you

0:29:28.600 --> 0:29:33.720
<v Speaker 1>could strive for, but you were never ever going to get. Uh.

0:29:33.800 --> 0:29:36.200
<v Speaker 1>He kind of arrived at this gradually. So in nine

0:29:37.520 --> 0:29:42.080
<v Speaker 1>he was involved in a bit of a spat, a debate,

0:29:42.160 --> 0:29:46.800
<v Speaker 1>if you will, about a theoretical spat actually was real

0:29:46.880 --> 0:29:50.480
<v Speaker 1>spat about theory. Uh, but it was on. So you

0:29:50.560 --> 0:29:54.520
<v Speaker 1>had two sides to this debate. You had Heisenberg and

0:29:54.680 --> 0:29:58.880
<v Speaker 1>his his fellow physicists who thought of quantum mechanics in

0:29:58.920 --> 0:30:02.080
<v Speaker 1>the term of these matrix these these this abstract mathematic

0:30:03.680 --> 0:30:07.200
<v Speaker 1>way of describing the position or motion of an electron,

0:30:07.560 --> 0:30:10.920
<v Speaker 1>because again he was arguing that you could not define

0:30:10.960 --> 0:30:13.960
<v Speaker 1>it in a way that was like it's at x,

0:30:14.120 --> 0:30:16.560
<v Speaker 1>y and z coordinates. You could not do that, right,

0:30:17.080 --> 0:30:19.360
<v Speaker 1>I was using the matrix. And there was another set

0:30:19.360 --> 0:30:22.360
<v Speaker 1>of scientists who were trying to describe some atomic particles

0:30:22.440 --> 0:30:25.880
<v Speaker 1>as as waves the way that we would electromagnetic radiation.

0:30:26.080 --> 0:30:31.040
<v Speaker 1>Uli r own Trodinger, Yeah, Schrodinger Singer and is kitty cat?

0:30:31.280 --> 0:30:35.360
<v Speaker 1>Actually Schrodinger and the cat story is kind of interesting,

0:30:35.400 --> 0:30:37.320
<v Speaker 1>just a little side notes. So you've probably heard of

0:30:37.320 --> 0:30:41.200
<v Speaker 1>Schrodinger's cat, where Schrodinger was, uh, kind of giving a

0:30:41.280 --> 0:30:46.240
<v Speaker 1>thought experiment kind of thing to explain how how this

0:30:46.240 --> 0:30:48.880
<v Speaker 1>this other form, the matrix form of quantum mechanics is

0:30:48.920 --> 0:30:51.280
<v Speaker 1>a little weird. The idea that you have a cat

0:30:51.320 --> 0:30:54.280
<v Speaker 1>inside a box, and inside that box you also have

0:30:54.560 --> 0:30:57.560
<v Speaker 1>a little canister with poisonous gas in it. And there's

0:30:57.600 --> 0:31:01.760
<v Speaker 1>some explosive that has a that that will go off

0:31:01.800 --> 0:31:05.280
<v Speaker 1>at some point and I am giving a variation classic.

0:31:06.920 --> 0:31:10.960
<v Speaker 1>So so within half an hour, there's a fifty chance

0:31:11.120 --> 0:31:14.120
<v Speaker 1>that the explosive inside that canstor has gone off and

0:31:14.160 --> 0:31:16.960
<v Speaker 1>released the poisonous gas and little killed the cat. Yes,

0:31:17.040 --> 0:31:20.280
<v Speaker 1>Kitty is no more. One life down, eight to go.

0:31:21.200 --> 0:31:24.520
<v Speaker 1>There's also a fifty percent chance that the that the

0:31:24.560 --> 0:31:28.640
<v Speaker 1>explosion has not yet happened, and that Kitty is fine

0:31:28.720 --> 0:31:32.400
<v Speaker 1>but possibly very bored inside this box. And so the

0:31:32.920 --> 0:31:37.280
<v Speaker 1>thing is that because of uh, this this weird quantum effect,

0:31:37.280 --> 0:31:39.400
<v Speaker 1>and keep in mind this is really something that only

0:31:39.480 --> 0:31:41.280
<v Speaker 1>happens at the quantum level. When you get up to

0:31:41.280 --> 0:31:44.960
<v Speaker 1>the macro level that we see this is not actually

0:31:44.960 --> 0:31:46.960
<v Speaker 1>the case. But the idea is that the cat is

0:31:46.960 --> 0:31:50.480
<v Speaker 1>both alive and dead at the same time, and superposition

0:31:50.800 --> 0:31:53.920
<v Speaker 1>that has both states and superposition, and it's only when

0:31:53.920 --> 0:31:56.720
<v Speaker 1>you open up the box and observe the cat that

0:31:56.960 --> 0:32:00.440
<v Speaker 1>one of those two possibilities becomes true is true, and

0:32:00.480 --> 0:32:04.160
<v Speaker 1>the other one just becomes yeah, it goes away, and

0:32:04.240 --> 0:32:07.040
<v Speaker 1>that then you have either the live cat or the

0:32:07.080 --> 0:32:09.040
<v Speaker 1>dead cat, so that the cat is said to be

0:32:09.080 --> 0:32:11.000
<v Speaker 1>alive and debt at the same time until you observe it,

0:32:11.040 --> 0:32:13.640
<v Speaker 1>and that's when reality snaps into place and you suddenly

0:32:13.720 --> 0:32:17.440
<v Speaker 1>get one of the two results. And it was kind

0:32:17.440 --> 0:32:19.400
<v Speaker 1>of a way of saying, like this is just, you know,

0:32:19.640 --> 0:32:23.480
<v Speaker 1>kind of crazy to be one of those things we

0:32:23.520 --> 0:32:27.000
<v Speaker 1>always refer to anyway. So Schroinger's cat and Heisenberg's and

0:32:27.000 --> 0:32:31.480
<v Speaker 1>certainty principle both are trying to explain various weird things

0:32:31.560 --> 0:32:34.400
<v Speaker 1>about the quantum level. There's another one that we can

0:32:34.400 --> 0:32:37.760
<v Speaker 1>touch on also that gets confused with Heisenberg's and certainty principle,

0:32:38.040 --> 0:32:40.959
<v Speaker 1>which is the idea that by observing something you actually

0:32:41.000 --> 0:32:44.840
<v Speaker 1>affect the outcome. So, in other words, when we're looking

0:32:44.880 --> 0:32:50.240
<v Speaker 1>at sub atomic particles, simply shining light onto them affects

0:32:50.240 --> 0:32:54.200
<v Speaker 1>their movement because we're talking about photons impacting subatomic particles,

0:32:54.200 --> 0:32:57.400
<v Speaker 1>which changes the pathway, which means just by taking an

0:32:57.400 --> 0:33:00.720
<v Speaker 1>observation in a measurement, you have changed what as what

0:33:00.800 --> 0:33:03.160
<v Speaker 1>was going to happen. So it makes it even more

0:33:03.600 --> 0:33:08.800
<v Speaker 1>impossible to predict things based upon the behaviors of stuff,

0:33:08.880 --> 0:33:12.200
<v Speaker 1>because just by observing it, you change what that outcome

0:33:12.240 --> 0:33:15.480
<v Speaker 1>actually is. Now that's not heisenberg'sun certainty principle either, but

0:33:15.520 --> 0:33:18.480
<v Speaker 1>it often gets confused. So we've got this debate. We've

0:33:18.520 --> 0:33:21.840
<v Speaker 1>got the wave mechanics debate, and that's Schrodinger's side, and

0:33:21.880 --> 0:33:25.000
<v Speaker 1>we've got the matrices debate, and that's heisenberg side. And

0:33:25.840 --> 0:33:31.440
<v Speaker 1>the debate was not always civil. Uh, there was there.

0:33:31.800 --> 0:33:35.120
<v Speaker 1>There was a quote that Heisenberg made to another physicist,

0:33:35.160 --> 0:33:38.600
<v Speaker 1>Wolfgang Ernst Pauli, which was, the more I think about

0:33:38.640 --> 0:33:42.000
<v Speaker 1>the physical portion of Schrodinger's theory, the more repulsive I

0:33:42.080 --> 0:33:47.800
<v Speaker 1>find it what Schrodinger writes about the visualizability. Visualizability, Boy,

0:33:47.880 --> 0:33:50.600
<v Speaker 1>that's a hard word. Of his theory is probably not

0:33:50.680 --> 0:33:54.920
<v Speaker 1>quite right. In other words, it's crap thick burn. Yeah,

0:33:54.920 --> 0:33:57.160
<v Speaker 1>that was a little that was a little rough. So

0:33:57.800 --> 0:34:01.040
<v Speaker 1>here's what the difference was between these two. Schroedinger's approach

0:34:01.080 --> 0:34:07.280
<v Speaker 1>required less complicated math to explain the relationship of a

0:34:07.360 --> 0:34:11.240
<v Speaker 1>subotomic particles movement and and and uh, it's it's position

0:34:11.440 --> 0:34:14.000
<v Speaker 1>around a nucleus, for example, an electron around the nucleus

0:34:14.000 --> 0:34:16.920
<v Speaker 1>as an example. But it furthermore explained some of the

0:34:17.000 --> 0:34:21.719
<v Speaker 1>things that Heisenberg's theory couldn't really fully explain. It's sort

0:34:21.719 --> 0:34:23.560
<v Speaker 1>of it's sort of pushed them under the rug in

0:34:23.560 --> 0:34:26.520
<v Speaker 1>a way, because Heisenberg's approach showed that there were these

0:34:26.560 --> 0:34:32.000
<v Speaker 1>little quantum jumps quantum leaps as if, yes, exactly, there's

0:34:32.120 --> 0:34:36.239
<v Speaker 1>quantum leaps when you cannot quite solve the problem, or

0:34:36.280 --> 0:34:37.640
<v Speaker 1>you solve the problem and then you have to leap

0:34:37.640 --> 0:34:39.719
<v Speaker 1>into the next body and hopefully your next leap is

0:34:39.719 --> 0:34:41.879
<v Speaker 1>the one that takes you home. No, in this case,

0:34:41.920 --> 0:34:44.879
<v Speaker 1>the quantum jumps were the fact that you would see

0:34:44.920 --> 0:34:47.960
<v Speaker 1>electrons behave in a weird way, like suddenly an electron

0:34:48.320 --> 0:34:51.000
<v Speaker 1>would behave as if it had a higher amount of

0:34:51.120 --> 0:34:54.880
<v Speaker 1>energy than it normally would, and that was, you know,

0:34:54.880 --> 0:34:59.520
<v Speaker 1>Heisenberg's approach showed these jumps well with Schroedinger's approach, because

0:34:59.560 --> 0:35:03.960
<v Speaker 1>we're talking a continuous wave a wave function. It smooths

0:35:04.000 --> 0:35:07.160
<v Speaker 1>everything out, so you don't have these jagged, you know jumps,

0:35:07.200 --> 0:35:12.440
<v Speaker 1>you have just a smooth transition um. So the Schrodinger's

0:35:12.520 --> 0:35:15.040
<v Speaker 1>argument was that, hey, you know, I've looked at the

0:35:15.040 --> 0:35:17.279
<v Speaker 1>way you are calculating this, and I look at the

0:35:17.320 --> 0:35:19.920
<v Speaker 1>way I'm calculating this, and it turns out the outcomes

0:35:19.920 --> 0:35:23.320
<v Speaker 1>are the same. We're getting the same results, but mine

0:35:23.360 --> 0:35:26.759
<v Speaker 1>requires less complicated math and not all this mathematic abstraction

0:35:26.800 --> 0:35:28.840
<v Speaker 1>that you are insisting upon. So therefore I'm right and

0:35:28.840 --> 0:35:32.080
<v Speaker 1>you're wrong, or at least mine is more eloquent. So

0:35:32.120 --> 0:35:36.280
<v Speaker 1>you've got these two parties of physicists getting a little

0:35:36.480 --> 0:35:42.319
<v Speaker 1>caddy schroedanjer caddy. Perhaps, um, there are alive cats and

0:35:42.880 --> 0:35:47.000
<v Speaker 1>dead cats. But then, uh, it's interesting because you started

0:35:47.040 --> 0:35:51.600
<v Speaker 1>getting into other physicists getting into the game, including Ernst

0:35:51.680 --> 0:35:55.760
<v Speaker 1>Pascual Jordan's or Jordans I suppose, who was a German

0:35:55.760 --> 0:35:58.480
<v Speaker 1>physicist who would actually later joined the Nazi Party become

0:35:58.840 --> 0:36:02.919
<v Speaker 1>part of that movement, in fact enlisted in the Luftwaffe Um.

0:36:02.960 --> 0:36:05.120
<v Speaker 1>And then you had Paul de Rak who was an

0:36:05.120 --> 0:36:09.840
<v Speaker 1>English physicist who both created unified equations that took the

0:36:10.000 --> 0:36:14.400
<v Speaker 1>wave function approach and the matrices approach and combine them

0:36:14.440 --> 0:36:17.279
<v Speaker 1>into what was called a transformation theory, which is the

0:36:17.360 --> 0:36:21.680
<v Speaker 1>very basis of quantum mechanics. So again this is all theoretical.

0:36:21.840 --> 0:36:26.920
<v Speaker 1>It's essentially trying physicists trying to figure out how to

0:36:26.920 --> 0:36:29.960
<v Speaker 1>to apply the same sort of observation that they had

0:36:29.960 --> 0:36:33.160
<v Speaker 1>in classical interpretation of physics on the macro scale to

0:36:33.400 --> 0:36:36.560
<v Speaker 1>the quantum level, which is the incredibly tiny scale, the

0:36:36.920 --> 0:36:40.759
<v Speaker 1>atomic or subatomic scale at which the rules do not apply. Right. So,

0:36:40.960 --> 0:36:44.080
<v Speaker 1>but the transformation theory ended up showing that there was

0:36:44.120 --> 0:36:47.200
<v Speaker 1>a combination of both Schroedinger's approach and Heisenberg's approach the

0:36:47.239 --> 0:36:51.279
<v Speaker 1>sort of wave particle duality that we know about with

0:36:51.360 --> 0:36:54.200
<v Speaker 1>quantum mechanics. That's kind of what was coming out of

0:36:54.239 --> 0:36:56.800
<v Speaker 1>this discussion. So instead of them both saying no, I'm right, no,

0:36:56.880 --> 0:36:59.520
<v Speaker 1>I'm right, these guys are like, well, actually you're both right.

0:36:59.760 --> 0:37:03.080
<v Speaker 1>Nic Yeah, light is a particle and a wave, and

0:37:03.160 --> 0:37:07.359
<v Speaker 1>it gets boy, toy doesn't get even more crazy, Like

0:37:07.880 --> 0:37:10.839
<v Speaker 1>it seems magical to those of us who are used

0:37:10.880 --> 0:37:14.760
<v Speaker 1>to classical physics on that macro scale, because if things

0:37:14.760 --> 0:37:16.960
<v Speaker 1>on the macro scale behave the same way that things

0:37:17.000 --> 0:37:19.600
<v Speaker 1>in the quantum scale behaved, it would be like we

0:37:19.600 --> 0:37:22.640
<v Speaker 1>were living in Harry Potter World or something right right there.

0:37:22.640 --> 0:37:24.040
<v Speaker 1>There would be a lot of a lot of you know,

0:37:24.120 --> 0:37:28.400
<v Speaker 1>people suddenly jumping to the left right, yeah, because you know,

0:37:28.560 --> 0:37:30.680
<v Speaker 1>or you could never really be sure where someone was

0:37:30.800 --> 0:37:33.000
<v Speaker 1>or how quickly they were moving and and emitting light.

0:37:33.040 --> 0:37:34.640
<v Speaker 1>When they did it, they'd be half dead and half

0:37:34.680 --> 0:37:36.799
<v Speaker 1>alive until you looked at them. Yeah, there's a whole

0:37:36.840 --> 0:37:39.360
<v Speaker 1>bunch of things that would be pretty bizarre in our world.

0:37:39.560 --> 0:37:41.600
<v Speaker 1>Lauren and I have a bit more to say about

0:37:41.719 --> 0:37:44.719
<v Speaker 1>Heisenberg in this classic episode, but before we get to that,

0:37:44.800 --> 0:37:55.480
<v Speaker 1>let's take a quick break and thank our sponsor. So,

0:37:55.680 --> 0:37:58.839
<v Speaker 1>Heisenberg studied Jordan and DeRos papers and found that there

0:37:58.840 --> 0:38:01.240
<v Speaker 1>were problems when ever each right to measure the basic

0:38:01.480 --> 0:38:05.800
<v Speaker 1>physical variables appearing in the equations. And by physical variables,

0:38:05.800 --> 0:38:09.080
<v Speaker 1>I mean an electrons position and its momentum. So that

0:38:09.160 --> 0:38:12.160
<v Speaker 1>led Heisenberg to create the famous principle of uncertainty, which

0:38:12.200 --> 0:38:16.320
<v Speaker 1>you did in ven. We usually call that Heisenberg's uncertainty principle.

0:38:16.960 --> 0:38:21.080
<v Speaker 1>So here's here's how it breaks down. The more precisely

0:38:21.200 --> 0:38:25.080
<v Speaker 1>you determine the position of a sub atomic particle, for example,

0:38:25.080 --> 0:38:27.120
<v Speaker 1>an electron around the nucleus. So the more precisely you

0:38:27.160 --> 0:38:31.080
<v Speaker 1>determine its position, the less precisely you can know about

0:38:31.120 --> 0:38:34.440
<v Speaker 1>the momentum at that moment, and vice versa. So if

0:38:34.440 --> 0:38:38.399
<v Speaker 1>you more precisely determine the subotomic particle's momentum, the less

0:38:38.400 --> 0:38:43.520
<v Speaker 1>precisely you can know its actual position. Right, Um, So Specifically,

0:38:43.640 --> 0:38:47.799
<v Speaker 1>he was saying that um that running the calculation for this,

0:38:47.920 --> 0:38:50.919
<v Speaker 1>for this determination of the position and the momentum um

0:38:51.040 --> 0:38:56.040
<v Speaker 1>necessarily contains errors, the product of which physically cannot be

0:38:56.200 --> 0:38:59.799
<v Speaker 1>less than the quantum constant h plucks constant, which is

0:39:00.160 --> 0:39:04.200
<v Speaker 1>that the smallest unit the quantum of action in an atom. Right,

0:39:04.520 --> 0:39:07.760
<v Speaker 1>And so what he's saying here is that it doesn't

0:39:07.800 --> 0:39:13.319
<v Speaker 1>matter how advanced your measurement apparatus is. In fact, there

0:39:13.360 --> 0:39:17.600
<v Speaker 1>was one point where More criticized Heisenberg's approach because he

0:39:17.640 --> 0:39:20.680
<v Speaker 1>said that he was using essentially microscopes that were not

0:39:20.719 --> 0:39:23.560
<v Speaker 1>precise enough, and in fact I made an error. And

0:39:23.600 --> 0:39:26.239
<v Speaker 1>then Heisenberg got really upset a Bore, and the two

0:39:26.320 --> 0:39:28.520
<v Speaker 1>of them had a falling out that lasted about a year,

0:39:29.000 --> 0:39:33.359
<v Speaker 1>and then Heisenberg eventually wrote a paper and acknowledge He said,

0:39:33.400 --> 0:39:35.719
<v Speaker 1>you know, Bore has criticized this because of such and such.

0:39:35.760 --> 0:39:37.920
<v Speaker 1>An acknowledged that in fact, there was an error, but

0:39:38.000 --> 0:39:41.479
<v Speaker 1>said that ultimately that error was beside the point because

0:39:41.480 --> 0:39:45.160
<v Speaker 1>it would not matter how precise that was, the fact

0:39:45.160 --> 0:39:47.399
<v Speaker 1>remained that the more you would learn about one thing,

0:39:47.440 --> 0:39:50.080
<v Speaker 1>the less you could know about the other. That's the

0:39:50.160 --> 0:39:53.200
<v Speaker 1>uncertainty or complimentarianism is another way that some people have

0:39:53.239 --> 0:39:57.319
<v Speaker 1>said that there's this complementary relationship between the momentum and

0:39:57.360 --> 0:40:00.080
<v Speaker 1>the position. So in case you want to know what

0:40:00.160 --> 0:40:04.080
<v Speaker 1>momentum is, that's mass times velocity, velossities that speed and direction.

0:40:04.680 --> 0:40:06.680
<v Speaker 1>So that's important to know. So on the human scale,

0:40:06.840 --> 0:40:10.000
<v Speaker 1>this uncertainty is completely negligible. There's you might as well

0:40:10.000 --> 0:40:11.840
<v Speaker 1>just throw it out the window because on our scale

0:40:11.840 --> 0:40:14.520
<v Speaker 1>it just doesn't that it doesn't factor into it. It's

0:40:14.560 --> 0:40:17.080
<v Speaker 1>such a tiny thing. But when you look at the

0:40:17.120 --> 0:40:20.239
<v Speaker 1>smaller scales, this tiny tiny thing becomes huge because you're

0:40:20.280 --> 0:40:24.840
<v Speaker 1>looking at things on an incredibly small scale. And because

0:40:24.840 --> 0:40:28.000
<v Speaker 1>we can't know but with precision both a subatomics particles

0:40:28.000 --> 0:40:31.400
<v Speaker 1>a position and its momentum, we cannot really make predictions

0:40:31.440 --> 0:40:33.600
<v Speaker 1>about what's going to happen in the future. And in fact,

0:40:34.160 --> 0:40:37.680
<v Speaker 1>uh this is where Heisenberg says causality becomes a problem

0:40:37.920 --> 0:40:42.520
<v Speaker 1>because if you cannot determine that subatomic particles position and momentum,

0:40:42.800 --> 0:40:46.200
<v Speaker 1>you cannot actually know what's going to happen next. So

0:40:46.320 --> 0:40:48.000
<v Speaker 1>if you were to expand this out, now this is

0:40:48.080 --> 0:40:50.360
<v Speaker 1>this is to the absurd, But if you were to

0:40:50.360 --> 0:40:52.279
<v Speaker 1>expand this out, you could say that you cannot for

0:40:52.360 --> 0:40:55.480
<v Speaker 1>certain know that by doing a certain action, a particular

0:40:55.520 --> 0:40:57.919
<v Speaker 1>effect is going to follow. That's not really the case

0:40:57.920 --> 0:41:01.200
<v Speaker 1>with classical physics again because we're talking up the macro scale,

0:41:01.280 --> 0:41:03.480
<v Speaker 1>but on the qualm scale, that's the case. We cannot

0:41:03.600 --> 0:41:06.400
<v Speaker 1>really know what will happen from one moment to the

0:41:06.400 --> 0:41:08.680
<v Speaker 1>next because we can't know enough about all the factors

0:41:08.680 --> 0:41:10.920
<v Speaker 1>to make that determination, which is which is kind of

0:41:10.920 --> 0:41:14.640
<v Speaker 1>wonderful and kind of terrifying right simultaneously, and though it's

0:41:14.640 --> 0:41:16.920
<v Speaker 1>a cat in a box yep. And and then this

0:41:17.160 --> 0:41:19.879
<v Speaker 1>also ties into that observation problem, right because if we

0:41:20.040 --> 0:41:23.600
<v Speaker 1>even if we observe the phenomenon, then we're affecting, we're

0:41:23.680 --> 0:41:26.600
<v Speaker 1>changing the phenomens. We're making it even more impossible to

0:41:26.680 --> 0:41:28.600
<v Speaker 1>determine what the effect is going to be. The cause

0:41:28.640 --> 0:41:31.600
<v Speaker 1>and effect at the scale is something that becomes purely

0:41:31.680 --> 0:41:34.600
<v Speaker 1>theoretical because as soon as you try and apply practical

0:41:34.600 --> 0:41:37.200
<v Speaker 1>approaches to it, it all breaks down. And we promise

0:41:37.280 --> 0:41:40.080
<v Speaker 1>this really does relate directly to technology. Yep, we're getting there.

0:41:40.320 --> 0:41:44.359
<v Speaker 1>So we then show that light can be interpreted as

0:41:44.360 --> 0:41:47.600
<v Speaker 1>both wave functions and as a particle. That's with Boor

0:41:47.719 --> 0:41:50.279
<v Speaker 1>and Heisenberg together working they were able to kind of

0:41:50.320 --> 0:41:54.320
<v Speaker 1>come to this conclusion. And as soon as you decide

0:41:54.360 --> 0:41:59.680
<v Speaker 1>how to observe a particular experiment, that interpretation becomes true

0:41:59.680 --> 0:42:02.040
<v Speaker 1>and the their interpretation collapses. So in other words, if

0:42:02.040 --> 0:42:04.080
<v Speaker 1>you're looking at light as a wave, you see it

0:42:04.160 --> 0:42:05.880
<v Speaker 1>as a wave. If you look at light as a particle,

0:42:05.920 --> 0:42:07.920
<v Speaker 1>you see it as a particle, and the other half

0:42:07.920 --> 0:42:12.680
<v Speaker 1>of that interpretation goes away, which is insane. They were

0:42:12.719 --> 0:42:15.240
<v Speaker 1>talking about it about how how you observe the experiment,

0:42:15.239 --> 0:42:19.800
<v Speaker 1>we disturb untouched nature and we become limited and learning

0:42:19.840 --> 0:42:22.480
<v Speaker 1>about nature as it really is. In other words, we

0:42:22.560 --> 0:42:27.880
<v Speaker 1>have a very narrow view into what reality is, and

0:42:27.960 --> 0:42:31.640
<v Speaker 1>once we focus that view on something, we cannot know

0:42:31.960 --> 0:42:35.680
<v Speaker 1>everything else that's outside of that view. So imagine that

0:42:35.719 --> 0:42:38.600
<v Speaker 1>you have a telescope and you are using that telescope

0:42:38.600 --> 0:42:42.319
<v Speaker 1>to look at something that's on the distant horizon, and

0:42:42.360 --> 0:42:44.359
<v Speaker 1>you can see that, you can see the thing that's

0:42:44.360 --> 0:42:47.239
<v Speaker 1>on the horizon, but everything else has faded away. It's

0:42:47.280 --> 0:42:49.960
<v Speaker 1>like all of that's just gone. That's kind of what

0:42:50.600 --> 0:42:53.440
<v Speaker 1>the sort of an analogy as to what he was

0:42:53.480 --> 0:42:56.320
<v Speaker 1>saying here, which is disturbing to think about in a way.

0:42:56.480 --> 0:42:59.160
<v Speaker 1>But that's how reality works, so you've got to kind

0:42:59.160 --> 0:43:02.920
<v Speaker 1>of deal with it um. So Heisenberg's uncertainty principle in

0:43:02.920 --> 0:43:06.840
<v Speaker 1>Shringer's wave functions become the basis of the Copenhagen interpretation

0:43:06.880 --> 0:43:11.160
<v Speaker 1>of quantum mechanics. And uh, the reason why we even

0:43:11.160 --> 0:43:13.160
<v Speaker 1>did this podcast besides the fact that I think someone

0:43:13.200 --> 0:43:17.160
<v Speaker 1>actually asked us to and Lauren's going to look that up,

0:43:17.200 --> 0:43:20.400
<v Speaker 1>but the reason why we're doing this is because Heisenberg's

0:43:20.440 --> 0:43:24.880
<v Speaker 1>uncertainty principle plays into the way that we use electronics today,

0:43:24.920 --> 0:43:28.239
<v Speaker 1>because now we're working with electronics that have components that

0:43:28.280 --> 0:43:32.160
<v Speaker 1>are on this tiny, tiny skin at least the nano scale,

0:43:32.200 --> 0:43:35.280
<v Speaker 1>which is one one factor up from atomic but far away.

0:43:35.400 --> 0:43:39.120
<v Speaker 1>The flow of electrons is critical for modern artronics absolutely,

0:43:39.239 --> 0:43:43.520
<v Speaker 1>and while we're making these tiny transistors or transistor elements

0:43:43.520 --> 0:43:46.160
<v Speaker 1>that are part of these integrated circuits, you know that

0:43:46.200 --> 0:43:48.680
<v Speaker 1>the whole purpose of transistors is to guide the flow

0:43:48.719 --> 0:43:50.560
<v Speaker 1>of electrons to allow them to pass or to not

0:43:50.600 --> 0:43:53.719
<v Speaker 1>allow them to pass through a circuit. Well, if you

0:43:53.800 --> 0:43:57.440
<v Speaker 1>make the gates really thin, then Heisenberg's and certainty principle

0:43:57.520 --> 0:44:01.160
<v Speaker 1>tells us that there is a kind of a zone

0:44:01.640 --> 0:44:04.920
<v Speaker 1>in which you might find an electron, and because of

0:44:04.960 --> 0:44:09.840
<v Speaker 1>the uncertainty about the electron's momentum or energy, sometimes that

0:44:09.960 --> 0:44:14.440
<v Speaker 1>electron can jump up an energy level because of our uncertainty.

0:44:14.480 --> 0:44:17.120
<v Speaker 1>We we you know, it just will pop up an

0:44:17.200 --> 0:44:19.719
<v Speaker 1>energy level and then pop back down, which means that

0:44:19.800 --> 0:44:21.800
<v Speaker 1>can be found in a slightly larger zone than you

0:44:21.840 --> 0:44:24.919
<v Speaker 1>would not necessarily expect based upon its actual energy level,

0:44:25.640 --> 0:44:28.880
<v Speaker 1>which can be problematic when when you've got these incredibly

0:44:28.880 --> 0:44:32.600
<v Speaker 1>thin gates that are supposed to be keeping an electrons

0:44:32.640 --> 0:44:35.760
<v Speaker 1>on one side, right that that zone might extend beyond

0:44:35.920 --> 0:44:38.440
<v Speaker 1>the far side of that gate. And if the zone

0:44:38.520 --> 0:44:40.399
<v Speaker 1>extends beyond the far side of the gate, that means

0:44:40.440 --> 0:44:43.560
<v Speaker 1>that it's possible for an electron to appear on the

0:44:43.560 --> 0:44:45.959
<v Speaker 1>other side of the gate without having actually passed through

0:44:46.000 --> 0:44:50.600
<v Speaker 1>that circuit, which means called electron tunneling. And since it's possible,

0:44:50.920 --> 0:44:56.000
<v Speaker 1>it happens, which which means that, yeah, unless we figure

0:44:56.000 --> 0:44:59.839
<v Speaker 1>out ways of getting around these you know, these these

0:45:00.000 --> 0:45:04.640
<v Speaker 1>fundamental quantum phenomena that we you know, there's a point

0:45:04.680 --> 0:45:07.360
<v Speaker 1>where you cannot make the components any smaller because the

0:45:07.400 --> 0:45:10.279
<v Speaker 1>electrons just won't play ball you're just gonna go every

0:45:10.520 --> 0:45:13.560
<v Speaker 1>way that the fundamental quantum traffic laws, as you put

0:45:13.600 --> 0:45:16.280
<v Speaker 1>it in our exactly. Yeah, yeah, it means that that

0:45:16.840 --> 0:45:19.920
<v Speaker 1>you're you're gonna get errors in your various chips because

0:45:19.960 --> 0:45:22.920
<v Speaker 1>they will not be allowing the or or preventing the

0:45:22.960 --> 0:45:25.080
<v Speaker 1>electrons from flowing the way they're supposed to, because the

0:45:25.160 --> 0:45:27.319
<v Speaker 1>electrons are just gonna be able to tunnel right through

0:45:28.120 --> 0:45:32.360
<v Speaker 1>when when those uh those energy levels bump up uncertainly.

0:45:32.680 --> 0:45:36.600
<v Speaker 1>It's bizarre, it's so weird to think about um. But

0:45:36.800 --> 0:45:39.360
<v Speaker 1>engineers have found ways of working around that, using different

0:45:39.400 --> 0:45:43.279
<v Speaker 1>materials that uh that that minimize this so that they

0:45:43.280 --> 0:45:45.600
<v Speaker 1>can continue to make things smaller and smaller. But we

0:45:45.640 --> 0:45:48.360
<v Speaker 1>will reach a point when that is just not going

0:45:48.400 --> 0:45:50.760
<v Speaker 1>to be the way that chips will be designed anymore.

0:45:50.800 --> 0:45:53.960
<v Speaker 1>Either will will plateau and we won't be able to

0:45:53.960 --> 0:45:57.880
<v Speaker 1>make chips with smaller components, or will find a different

0:45:57.920 --> 0:46:02.560
<v Speaker 1>means of using suba comic particles to process information, and

0:46:02.560 --> 0:46:06.319
<v Speaker 1>we'll move away from electron based chips, which is hard

0:46:06.360 --> 0:46:09.640
<v Speaker 1>to consider. It's really weird to think about. Yeah, that's

0:46:09.680 --> 0:46:12.600
<v Speaker 1>not that that that is beyond my entire brain right now. Yeah, No,

0:46:13.000 --> 0:46:16.680
<v Speaker 1>I'm actually starting to feel a nosebleed coming on because

0:46:16.920 --> 0:46:19.560
<v Speaker 1>I'm a I'm an English literature major. Al Right, well,

0:46:19.600 --> 0:46:21.640
<v Speaker 1>let's let's let's bring this back to something, to something

0:46:21.680 --> 0:46:24.120
<v Speaker 1>a little bit more peaceful and serene. I have I

0:46:24.160 --> 0:46:27.680
<v Speaker 1>have a quote from Heisenberg via via pbs um. He

0:46:27.760 --> 0:46:31.360
<v Speaker 1>once said, natural science does not simply describe and explain nature.

0:46:31.760 --> 0:46:34.840
<v Speaker 1>It's part of the interplay between nature and ourselves. It

0:46:34.920 --> 0:46:38.600
<v Speaker 1>describes nature as exposed to our method of questioning. That's

0:46:38.680 --> 0:46:41.000
<v Speaker 1>pretty cool, which I thought was nice. I thought that

0:46:41.000 --> 0:46:44.600
<v Speaker 1>that was a much less nosebleedy way of saying that

0:46:44.600 --> 0:46:47.839
<v Speaker 1>that we mess stuff up scientifically. And also it also

0:46:47.960 --> 0:46:51.120
<v Speaker 1>is less uh nasty than his note to U or

0:46:51.239 --> 0:46:54.920
<v Speaker 1>note about Schrodinger. Right. So um oh, I found the

0:46:55.000 --> 0:46:58.960
<v Speaker 1>name of the person who requested this via Facebook. This

0:46:59.120 --> 0:47:01.920
<v Speaker 1>was from listener Peter. So Peter asked us about this,

0:47:02.000 --> 0:47:04.640
<v Speaker 1>and I hope that we were able to answer your

0:47:04.719 --> 0:47:08.080
<v Speaker 1>questions to uh your satisfaction. It was certainly to the

0:47:08.080 --> 0:47:10.279
<v Speaker 1>best of our ability, keeping in mind that neither of

0:47:10.360 --> 0:47:14.759
<v Speaker 1>us are theoretical physicists or mathematicians for that matter. Uh.

0:47:15.080 --> 0:47:17.960
<v Speaker 1>Fascinating subject and there are a lot of books out

0:47:18.000 --> 0:47:22.040
<v Speaker 1>there that are really really good about explaining Heisenberg's role

0:47:22.120 --> 0:47:26.840
<v Speaker 1>and also the contributions of his contemporaries, everyone from Einstein

0:47:26.920 --> 0:47:32.200
<v Speaker 1>to Somerville to Schrodinger to Toll, all the great physicists

0:47:32.200 --> 0:47:36.000
<v Speaker 1>of the nineteen twenties and thirties who have really made

0:47:36.440 --> 0:47:40.160
<v Speaker 1>modern technology possible through their discoveries. Well, guys, I hope

0:47:40.200 --> 0:47:42.560
