1 00:00:02,400 --> 00:00:06,480 Speaker 1: Hello everyone, we have another birthday edition of our Saturday Classics. 2 00:00:06,519 --> 00:00:10,719 Speaker 1: Today it is Emmy Nurture, who was a groundbreaking mathematician 3 00:00:10,720 --> 00:00:15,040 Speaker 1: and was born March two. We hope you enjoy her 4 00:00:15,120 --> 00:00:21,480 Speaker 1: mathematical world. Welcome to Stuff you Missed in History Class 5 00:00:21,760 --> 00:00:30,680 Speaker 1: from how Stuff Works dot com. Hello, and welcome to 6 00:00:30,680 --> 00:00:34,080 Speaker 1: the podcast. I'm CALLI Frying. I'm Tracy B. Wilson, and 7 00:00:34,159 --> 00:00:36,360 Speaker 1: today we're going to talk about a subject that was 8 00:00:36,400 --> 00:00:38,640 Speaker 1: directly inspired by a listener mail. And we're going to 9 00:00:38,720 --> 00:00:41,279 Speaker 1: talk in some detail about that listener mail at the end, 10 00:00:42,040 --> 00:00:43,920 Speaker 1: but just know that it did and we'll credit the 11 00:00:43,960 --> 00:00:46,440 Speaker 1: person when we get to the end, because it's pretty spectacular. 12 00:00:46,920 --> 00:00:50,240 Speaker 1: We're gonna talk about a really important lady mathematician and 13 00:00:50,560 --> 00:00:53,199 Speaker 1: her the pronunciation of her name is a matter of 14 00:00:53,240 --> 00:00:57,080 Speaker 1: some debate here at the office and online. Uh so 15 00:00:57,120 --> 00:01:00,000 Speaker 1: it's Emily Nurture. You will sometimes also hear it pronounced 16 00:01:00,040 --> 00:01:03,200 Speaker 1: more like nuture. Well, and then when I looked it 17 00:01:03,280 --> 00:01:07,480 Speaker 1: up at four vough, the one German speaker pronounced it 18 00:01:07,520 --> 00:01:10,399 Speaker 1: more like yeah, and I was like, we can't say 19 00:01:10,440 --> 00:01:12,360 Speaker 1: it that way. That's not gonna work. So I think 20 00:01:12,400 --> 00:01:15,759 Speaker 1: we decided we're going to hover right around Nurture that 21 00:01:16,600 --> 00:01:19,839 Speaker 1: with all our possible respects to Emmy, and I hope 22 00:01:19,840 --> 00:01:23,640 Speaker 1: we do not offend her ghosts should it exist, or 23 00:01:23,720 --> 00:01:26,560 Speaker 1: German speakers, or German speakers, or people who love math 24 00:01:26,640 --> 00:01:28,760 Speaker 1: and love her as a figure. So we're just going 25 00:01:28,800 --> 00:01:31,880 Speaker 1: to jump right into talking about her. Emmy was born 26 00:01:32,000 --> 00:01:37,720 Speaker 1: Emily Emmy Nurture on March two in Erlangen, Germany, and 27 00:01:37,800 --> 00:01:42,319 Speaker 1: her father, Max Nurture, was a mathematician. Her mother, Ida 28 00:01:42,400 --> 00:01:45,680 Speaker 1: Amalia Kaufman, was from a very well to do family, 29 00:01:45,760 --> 00:01:49,200 Speaker 1: and after Emmy was born, Max and Ida had three sons, 30 00:01:49,240 --> 00:01:51,400 Speaker 1: although two of them died when they were very young, 31 00:01:52,000 --> 00:01:56,480 Speaker 1: only Emmy's brother, Fritz, survived to adulthood. And as a 32 00:01:56,480 --> 00:01:59,600 Speaker 1: young child, by most accounts, Emmy did not really stand 33 00:01:59,600 --> 00:02:02,240 Speaker 1: out as a specially gifted. She was a bright child, 34 00:02:02,280 --> 00:02:05,400 Speaker 1: but nobody was like, this is the future of mathematics. 35 00:02:05,440 --> 00:02:10,640 Speaker 1: She attended the State Girls School in Erlangen from ninety seven, 36 00:02:10,680 --> 00:02:13,720 Speaker 1: studying the basics of school curriculum, and she also took 37 00:02:13,720 --> 00:02:16,480 Speaker 1: piano lessons, and she learned to speak French and English, 38 00:02:16,520 --> 00:02:19,080 Speaker 1: and as she grew into her teen years, she loved 39 00:02:19,160 --> 00:02:21,440 Speaker 1: dancing and she was known as a very friendly, clever girl. 40 00:02:21,840 --> 00:02:24,440 Speaker 1: When she was eighteen, she was certified to teach both 41 00:02:24,480 --> 00:02:27,200 Speaker 1: French and English, and the series of exams that she 42 00:02:27,280 --> 00:02:29,680 Speaker 1: had to go through to get this certification was pretty 43 00:02:29,680 --> 00:02:32,440 Speaker 1: strenuous that it took four days for her to do this. 44 00:02:33,040 --> 00:02:36,720 Speaker 1: But instead of settling into a career teaching in girls schools, 45 00:02:37,120 --> 00:02:40,400 Speaker 1: she decided that she would go to university and study mathematics. 46 00:02:41,320 --> 00:02:44,000 Speaker 1: And this was a pretty big jump to suddenly make. 47 00:02:44,040 --> 00:02:46,360 Speaker 1: And we don't know why Emmy had this sudden shift 48 00:02:46,440 --> 00:02:49,560 Speaker 1: in interests. Her life up to this point had seemed 49 00:02:49,600 --> 00:02:52,120 Speaker 1: to follow a pretty standard course for a young woman 50 00:02:52,919 --> 00:02:56,000 Speaker 1: in that period of time in Germany from an intellectual, 51 00:02:56,000 --> 00:02:58,919 Speaker 1: middle class family. You know, she would potentially get married, 52 00:02:58,919 --> 00:03:01,000 Speaker 1: but if not, she had this cup job as a teacher. 53 00:03:01,520 --> 00:03:03,760 Speaker 1: And none of her personal writing from this time has 54 00:03:03,800 --> 00:03:06,880 Speaker 1: survived to offer us any clues why she suddenly decided 55 00:03:06,919 --> 00:03:10,320 Speaker 1: that what she really wanted was to pursue a mathematics career. Yeah, 56 00:03:10,360 --> 00:03:14,079 Speaker 1: we do know that it wasn't a completely foreign subject 57 00:03:14,080 --> 00:03:16,960 Speaker 1: to her. Her brother Fritz was studying mathematics at the time, 58 00:03:17,320 --> 00:03:20,799 Speaker 1: and her father also entertained other mathematicians in their home 59 00:03:20,880 --> 00:03:23,000 Speaker 1: from time to time. So she had been around the 60 00:03:23,080 --> 00:03:26,320 Speaker 1: subject of math her whole life. So while it does 61 00:03:26,360 --> 00:03:28,919 Speaker 1: seem like quite a shift to go from teaching French 62 00:03:28,919 --> 00:03:31,800 Speaker 1: and English to studying math, it wasn't something that was 63 00:03:31,840 --> 00:03:35,960 Speaker 1: completely new to her. And just the same though, this 64 00:03:36,040 --> 00:03:40,520 Speaker 1: desire to take university courses was incredibly ambitious. So the 65 00:03:40,600 --> 00:03:43,680 Speaker 1: schooling that girls received at this time in Germany was 66 00:03:43,760 --> 00:03:46,160 Speaker 1: vastly different from the way that the boys were educated. 67 00:03:46,320 --> 00:03:48,080 Speaker 1: The goal for a girls school was to turn out 68 00:03:48,120 --> 00:03:51,240 Speaker 1: proper young ladies or trade workers, depending on the young 69 00:03:51,280 --> 00:03:54,920 Speaker 1: woman's family background, and they just simply did not receive 70 00:03:55,400 --> 00:03:58,360 Speaker 1: the kind of educational groundwork that would make a transition 71 00:03:58,400 --> 00:04:03,440 Speaker 1: to university studies a natural step. Regardless of exactly how 72 00:04:03,480 --> 00:04:06,160 Speaker 1: it was that she arrived at this decision, Emmy went 73 00:04:06,200 --> 00:04:09,560 Speaker 1: to the University of our Langen to continue her education. 74 00:04:09,960 --> 00:04:12,800 Speaker 1: But because she was a woman and it was she 75 00:04:12,800 --> 00:04:16,479 Speaker 1: couldn't just enroll in classes. She had to get special 76 00:04:16,520 --> 00:04:20,360 Speaker 1: permission from every instructor of every class, and then she 77 00:04:20,400 --> 00:04:23,680 Speaker 1: couldn't actually enroll as a regular student. She could only 78 00:04:23,720 --> 00:04:26,919 Speaker 1: audit the class. She had to once again get special 79 00:04:26,960 --> 00:04:32,160 Speaker 1: permission to actually take the exams from the instructors. Yeah, 80 00:04:32,320 --> 00:04:36,280 Speaker 1: so she uh really had to jump through every imaginable 81 00:04:36,320 --> 00:04:38,600 Speaker 1: hoop just to get this math education that she had 82 00:04:38,640 --> 00:04:42,479 Speaker 1: decided she wanted. Um. In July three, Emmy took the 83 00:04:42,600 --> 00:04:45,880 Speaker 1: enrollment exam for the university at the Royal Gymnasium in 84 00:04:45,960 --> 00:04:49,479 Speaker 1: Nuremberg and she passed, basically, proving at that point that 85 00:04:49,520 --> 00:04:52,520 Speaker 1: she was even with male classmates despite having missed their 86 00:04:52,680 --> 00:04:55,880 Speaker 1: educational background. After the exam, in the summer and he 87 00:04:55,920 --> 00:05:00,360 Speaker 1: started auditing advanced mathematics courses at the University of Linen, 88 00:05:00,839 --> 00:05:03,320 Speaker 1: and that started in the winter of nineteen oh three 89 00:05:03,320 --> 00:05:07,200 Speaker 1: oh four. During these winter courses, she learned from teachers 90 00:05:07,240 --> 00:05:10,640 Speaker 1: who would make incredible contributions in the world of mathematics. 91 00:05:11,200 --> 00:05:14,520 Speaker 1: Herman Minkowski, for example, developed the geometry of numbers. He 92 00:05:14,560 --> 00:05:18,240 Speaker 1: contributed to number theory, and he worked on relativity, influencing 93 00:05:18,360 --> 00:05:23,000 Speaker 1: his famous student Albert Einstein. David Hilbert, another of her instructors, 94 00:05:23,000 --> 00:05:27,400 Speaker 1: set the foundations for functional analysis. Felix Klein influenced the 95 00:05:27,440 --> 00:05:30,479 Speaker 1: development of mathematics is it related to representing the properties 96 00:05:30,520 --> 00:05:33,880 Speaker 1: of space and spatial relations through geometry. So she was 97 00:05:33,960 --> 00:05:37,320 Speaker 1: learning from serious heavy hitters. But in nineteen o four 98 00:05:37,520 --> 00:05:40,080 Speaker 1: she went back to the University of Erlangen because the 99 00:05:40,120 --> 00:05:44,320 Speaker 1: school had started actually accepting women as for real legitimate students. 100 00:05:44,760 --> 00:05:48,560 Speaker 1: On October nineteen o four, she was officially enrolled as 101 00:05:48,600 --> 00:05:51,760 Speaker 1: student number four eighties six, and she was the only 102 00:05:51,920 --> 00:05:56,160 Speaker 1: woman student in a field of forty seven. Emmy's mentor 103 00:05:56,320 --> 00:05:58,840 Speaker 1: during this time was Paul Gordon, who was a friend 104 00:05:58,880 --> 00:06:01,599 Speaker 1: of her father's as well as an influential mathematician in 105 00:06:01,680 --> 00:06:04,000 Speaker 1: his own right, and Emmy had known him since she 106 00:06:04,080 --> 00:06:06,800 Speaker 1: was just a child. He was very close with her 107 00:06:06,839 --> 00:06:09,120 Speaker 1: family and he has often described as sort of a 108 00:06:09,160 --> 00:06:12,720 Speaker 1: second father figure to her. He was, however, in terms 109 00:06:12,760 --> 00:06:16,760 Speaker 1: of personality, a stark contrast to her father. Max Air 110 00:06:16,880 --> 00:06:20,040 Speaker 1: Nurture was gentle and warm. He was passionate about his work, 111 00:06:20,120 --> 00:06:22,280 Speaker 1: but he is always described as sort of having this 112 00:06:22,640 --> 00:06:27,320 Speaker 1: overlying sense of calm about him. Gordon, who was nicknamed 113 00:06:27,520 --> 00:06:31,000 Speaker 1: the King of invariant Theory, was unlike Max, a more 114 00:06:31,120 --> 00:06:35,680 Speaker 1: dramatic figure. He was impulsive, He was expressive in very 115 00:06:35,760 --> 00:06:40,240 Speaker 1: unbridled ways. He was given to wild gesticulation while he 116 00:06:40,279 --> 00:06:43,680 Speaker 1: was talking, which I can identify with. Emmy was the 117 00:06:43,760 --> 00:06:46,960 Speaker 1: only doctorate student that that he ever mentored, and she 118 00:06:47,080 --> 00:06:49,640 Speaker 1: was really devoted to him. She kept a photo of 119 00:06:49,720 --> 00:06:52,080 Speaker 1: him on her wall for the rest of her life. 120 00:06:53,360 --> 00:06:57,039 Speaker 1: And it's interesting when people describe Emmy's behavior, she is 121 00:06:57,120 --> 00:07:01,320 Speaker 1: sometimes described as having traits that are in some ways 122 00:07:01,320 --> 00:07:04,080 Speaker 1: more similar to Paul Gordon than her father, like she 123 00:07:04,160 --> 00:07:08,119 Speaker 1: too was given to serious gesticulation and kind of would 124 00:07:08,120 --> 00:07:10,840 Speaker 1: make messes and be very dramatic and very excited and 125 00:07:10,880 --> 00:07:13,480 Speaker 1: so passionate that she would kind of lose herself. But 126 00:07:14,560 --> 00:07:18,440 Speaker 1: she received her PhD in mathematics from Erlangen after several 127 00:07:18,520 --> 00:07:22,040 Speaker 1: years as Gordon's protege, and her thesis was a dissertation 128 00:07:22,040 --> 00:07:26,120 Speaker 1: on algebraic invariance, which she successfully defended on December thirteenth 129 00:07:26,120 --> 00:07:29,240 Speaker 1: of nineteen o seven. She was given her degree sumakun 130 00:07:29,320 --> 00:07:32,840 Speaker 1: lauda on July two of the following year. This timing 131 00:07:32,960 --> 00:07:36,400 Speaker 1: is really significant because co ed classes were not a 132 00:07:36,560 --> 00:07:39,679 Speaker 1: thing in Germany until nineteen o eight, the year after 133 00:07:39,800 --> 00:07:44,240 Speaker 1: she successfully defended her thesis. Any woman who had gone 134 00:07:44,240 --> 00:07:47,400 Speaker 1: through the education system prior to that had, like Emmy, 135 00:07:47,680 --> 00:07:50,800 Speaker 1: had to get special permission and was not granted equal 136 00:07:50,840 --> 00:07:54,040 Speaker 1: students status. Yeah, just for clarity, we mentioned that she 137 00:07:54,160 --> 00:07:57,120 Speaker 1: returned to Erlangen because they were doing it, but in 138 00:07:57,200 --> 00:08:00,679 Speaker 1: terms of Germany wide, women were still not considered equal 139 00:08:00,760 --> 00:08:05,080 Speaker 1: until that year after she defended her thesis, and in 140 00:08:05,200 --> 00:08:09,800 Speaker 1: nineteen o eight, Emmy attended the International Mathematical Congress in Rome, Italy, 141 00:08:09,840 --> 00:08:12,480 Speaker 1: and she attended that along with her father. She was 142 00:08:12,560 --> 00:08:15,080 Speaker 1: at this point still a young woman and relatively unknown, 143 00:08:15,160 --> 00:08:18,120 Speaker 1: despite sort of making this name for herself as an 144 00:08:18,200 --> 00:08:21,360 Speaker 1: unusual figure being a woman in a very male dominated field, 145 00:08:21,680 --> 00:08:24,280 Speaker 1: so it seems that during this particular conference she really 146 00:08:24,360 --> 00:08:29,880 Speaker 1: kept a fairly low profile. After Ms Nurture received her PhD, 147 00:08:29,960 --> 00:08:33,280 Speaker 1: she continued her research work at their Lingen, although she 148 00:08:33,480 --> 00:08:36,600 Speaker 1: wasn't paid for any of this work. She assisted her 149 00:08:36,600 --> 00:08:39,400 Speaker 1: father in his research and then she was invited in 150 00:08:39,520 --> 00:08:43,040 Speaker 1: nineteen o eight to join the Cholo Mathematico in Italy 151 00:08:43,240 --> 00:08:46,120 Speaker 1: and then in nineteen o nine the German Mathematical Union. 152 00:08:47,160 --> 00:08:50,000 Speaker 1: Emmy's first sort of professional lecture was in nineteen o 153 00:08:50,160 --> 00:08:53,319 Speaker 1: nine at the Salzburg meeting of the German Mathematical Union. 154 00:08:54,200 --> 00:08:56,560 Speaker 1: She lectured at the Vienna chapter of the group several 155 00:08:56,640 --> 00:08:59,280 Speaker 1: years later in nineteen thirteen, and not long after that 156 00:08:59,360 --> 00:09:01,719 Speaker 1: she also started guest lecturing for her father as a 157 00:09:01,760 --> 00:09:05,000 Speaker 1: substitute and during this same period. Although as we said, 158 00:09:05,040 --> 00:09:07,480 Speaker 1: we don't have writings from her, so we don't really 159 00:09:07,520 --> 00:09:11,600 Speaker 1: know how this impacted her, but surely it did. Emmy's mentor, 160 00:09:11,640 --> 00:09:14,320 Speaker 1: Paul Gordan, died in nineteen twelve, so just as her 161 00:09:14,360 --> 00:09:17,120 Speaker 1: career was taking off. So next up we're going to 162 00:09:17,120 --> 00:09:20,720 Speaker 1: talk about a significant move in Emmy's life. But before that, 163 00:09:20,880 --> 00:09:23,560 Speaker 1: let's have a word from one of our awesome sponsors, 164 00:09:23,559 --> 00:09:25,800 Speaker 1: who keep the lights on here in our studio. That 165 00:09:25,880 --> 00:09:38,439 Speaker 1: sounds grand. So after eight years of post pH d 166 00:09:38,600 --> 00:09:41,920 Speaker 1: work at er Langen, her former teachers David Hilbert and 167 00:09:41,960 --> 00:09:44,920 Speaker 1: Felix Klein asked her to come back to gutting In 168 00:09:44,920 --> 00:09:48,280 Speaker 1: in nineteen fifteen. And this was right after Albert Einstein 169 00:09:48,320 --> 00:09:51,120 Speaker 1: had published his Theory of General Relativity and Klein and 170 00:09:51,200 --> 00:09:54,280 Speaker 1: Hilbert wanted Nurture to work with them on unraveling the 171 00:09:54,360 --> 00:09:58,080 Speaker 1: mathematics that were involved in Einstein's work. And Nurture had 172 00:09:58,120 --> 00:10:00,840 Speaker 1: published several papers of her own by this time, and 173 00:10:00,880 --> 00:10:04,880 Speaker 1: she had really exhibited some insightful approaches to mathematical concepts, 174 00:10:04,880 --> 00:10:07,800 Speaker 1: so she was the perfect candidate to assist in Hilbert 175 00:10:07,800 --> 00:10:11,600 Speaker 1: Incline's work. She went to Goettingen, but this move turned 176 00:10:11,600 --> 00:10:16,280 Speaker 1: out to be extremely controversial. Many faculty members objected to 177 00:10:16,320 --> 00:10:19,360 Speaker 1: the idea of a woman on the teaching staff. If 178 00:10:19,400 --> 00:10:23,240 Speaker 1: Emmy notre couldn't be granted faculty status, Hilbert and Kline 179 00:10:23,320 --> 00:10:26,760 Speaker 1: wanted Hurt to at least have what's called a privat descent, 180 00:10:26,920 --> 00:10:29,760 Speaker 1: which is a position similar to a post doc. It 181 00:10:29,800 --> 00:10:33,679 Speaker 1: would have given Emmy at least an officially recognized post 182 00:10:33,800 --> 00:10:37,920 Speaker 1: within the Good Educational system, would also grant her sufficient 183 00:10:37,960 --> 00:10:42,679 Speaker 1: title and permission to teach for nurtures thesis to be accepted, 184 00:10:42,720 --> 00:10:45,760 Speaker 1: and for her to be granted this privat, the entire 185 00:10:45,880 --> 00:10:49,280 Speaker 1: philosophy faculty had to vote on it. And this umbrella 186 00:10:49,360 --> 00:10:52,600 Speaker 1: of philosophy, keep in mind, included not only philosophy, but 187 00:10:52,640 --> 00:10:56,400 Speaker 1: also history, natural sciences, and mathematics. And it turned out 188 00:10:56,400 --> 00:10:59,640 Speaker 1: that the math people there were pretty cool with Emmy, 189 00:11:00,120 --> 00:11:03,160 Speaker 1: but the non mathematics people in the mix, we're really 190 00:11:03,240 --> 00:11:09,520 Speaker 1: vehemently arguing against having a woman teach students. The arguments 191 00:11:09,559 --> 00:11:13,360 Speaker 1: against Nurture were that giving her a provactance and position 192 00:11:14,080 --> 00:11:16,520 Speaker 1: would mean that she was on track to be faculty 193 00:11:16,760 --> 00:11:19,400 Speaker 1: and what would the returning soldiers think when they came 194 00:11:19,400 --> 00:11:21,400 Speaker 1: back to war to find that they're supposed to take 195 00:11:21,440 --> 00:11:24,760 Speaker 1: classes from a woman. Yeah, they really framed it like 196 00:11:24,800 --> 00:11:26,560 Speaker 1: what a slap in the face that would be these 197 00:11:26,640 --> 00:11:30,040 Speaker 1: young men who had gone to defend the ideals of 198 00:11:30,040 --> 00:11:33,200 Speaker 1: Germany and they then come back and find a lady teacher. 199 00:11:34,080 --> 00:11:38,480 Speaker 1: Well yeah, and keep in mind, this wasn't even soldiers 200 00:11:38,480 --> 00:11:40,679 Speaker 1: saying this. This was kind of the weird trumped up 201 00:11:40,760 --> 00:11:43,800 Speaker 1: argument that the non mathematics faculty was trying to put 202 00:11:43,840 --> 00:11:47,400 Speaker 1: together to keep Eman Nurture off of their cool kids club. 203 00:11:48,240 --> 00:11:53,520 Speaker 1: And her mentor and now colleague Hilbert's response was, gentlemen, 204 00:11:53,559 --> 00:11:55,520 Speaker 1: I do not see that the sex of the candidate 205 00:11:55,559 --> 00:11:58,280 Speaker 1: is an argument against her admission as a privatdot sent 206 00:11:58,760 --> 00:12:01,240 Speaker 1: After all, the sent it is not a bath house, 207 00:12:01,600 --> 00:12:04,800 Speaker 1: and he meant like the educational Senate, not their uh 208 00:12:05,080 --> 00:12:09,320 Speaker 1: government Senate. And his argument, though, didn't sway the detractors, 209 00:12:09,400 --> 00:12:12,800 Speaker 1: and Emmy was not granted this title. Hilbert and Klein 210 00:12:12,920 --> 00:12:17,720 Speaker 1: had to convince Nurta to stay for obvious reasons, but 211 00:12:17,840 --> 00:12:20,439 Speaker 1: she couldn't lecture under her own name, so they had 212 00:12:20,440 --> 00:12:22,600 Speaker 1: to come up with a sneaky kind of work around. 213 00:12:22,960 --> 00:12:26,920 Speaker 1: The lectures were listed under Hilbert's name, but Nurture was 214 00:12:26,960 --> 00:12:30,840 Speaker 1: the one who actually delivered them. Yeah, she worked under 215 00:12:31,720 --> 00:12:37,199 Speaker 1: his name for quite some time. Um in eighteen. However, 216 00:12:37,320 --> 00:12:40,440 Speaker 1: she has been doing this sort of sneaky workaround plan 217 00:12:40,559 --> 00:12:45,400 Speaker 1: for several years. At this point, she had developed at 218 00:12:45,480 --> 00:12:49,079 Speaker 1: through her work with Hilbert Kleine Nurture's theorem, which deals 219 00:12:49,120 --> 00:12:51,359 Speaker 1: with the relation between what are known as the symmetries 220 00:12:51,400 --> 00:12:55,040 Speaker 1: of a physical system and its conservation laws. So among 221 00:12:55,120 --> 00:12:58,000 Speaker 1: the revelations of this theorem is the linkage between time 222 00:12:58,040 --> 00:13:02,040 Speaker 1: and energy, directly related to the idea of conservation of energy, 223 00:13:02,120 --> 00:13:03,880 Speaker 1: so that in case you do not remember, is that 224 00:13:04,000 --> 00:13:08,240 Speaker 1: energy can neither be created nor destroyed, but merely changes form. 225 00:13:08,280 --> 00:13:11,800 Speaker 1: And this is incredibly significant stuff. I mean, this is 226 00:13:11,840 --> 00:13:15,000 Speaker 1: really a huge part of physics as we know it, right. 227 00:13:15,080 --> 00:13:18,520 Speaker 1: It's an incredibly important concept at theoretical physics, and her 228 00:13:18,600 --> 00:13:23,000 Speaker 1: peers at the time recognized its significance, so much so 229 00:13:23,080 --> 00:13:26,240 Speaker 1: that the following year, Emmy not Are was finally officially 230 00:13:26,960 --> 00:13:31,280 Speaker 1: recognized as an academic lecture with the privit zodes and 231 00:13:31,440 --> 00:13:33,960 Speaker 1: title that we've been talking about for so long she 232 00:13:34,000 --> 00:13:36,760 Speaker 1: had to lecture without. She no longer had to lecture 233 00:13:36,880 --> 00:13:41,720 Speaker 1: under a male mentor's name, and this was obviously incredibly significant, 234 00:13:42,160 --> 00:13:45,160 Speaker 1: but uh, it's not maybe the huge win that we 235 00:13:45,200 --> 00:13:47,920 Speaker 1: would all be hoping for, because, just to be clear, 236 00:13:47,960 --> 00:13:51,320 Speaker 1: at this point, emmy noture was in her thirties, she 237 00:13:51,400 --> 00:13:55,040 Speaker 1: had published numerous influential and important papers, and she was 238 00:13:55,040 --> 00:13:57,679 Speaker 1: working with the best mathematicians at the time as a 239 00:13:57,800 --> 00:14:02,680 Speaker 1: respected peer of theirs on the mathematics of relativity. And 240 00:14:02,760 --> 00:14:05,559 Speaker 1: despite all of that, she had up to this official 241 00:14:05,920 --> 00:14:07,600 Speaker 1: um you know, kind of track to be in a 242 00:14:07,640 --> 00:14:11,560 Speaker 1: faculty position. She had zero stability or safety in her career. 243 00:14:12,440 --> 00:14:15,160 Speaker 1: But even though she now had a title but made 244 00:14:15,160 --> 00:14:18,840 Speaker 1: it okay for her to lecture as herself, her position 245 00:14:18,880 --> 00:14:21,080 Speaker 1: did not actually come with any pay. She would not 246 00:14:21,120 --> 00:14:24,680 Speaker 1: get any pay as a lecture until nineteen three, four 247 00:14:24,760 --> 00:14:27,880 Speaker 1: years after she was made of private dotes in. Yeah, 248 00:14:28,000 --> 00:14:31,280 Speaker 1: we don't know exactly where the money was coming that 249 00:14:31,360 --> 00:14:33,920 Speaker 1: supported her. Uh, this is one of those kind of 250 00:14:34,440 --> 00:14:39,280 Speaker 1: wiggily fuzzy points. Presumably she was getting some from like 251 00:14:39,280 --> 00:14:42,920 Speaker 1: a family fund and possibly sort of private grants from 252 00:14:42,920 --> 00:14:47,160 Speaker 1: other mathematicians, but we don't really knew. In she collaborated 253 00:14:47,160 --> 00:14:50,720 Speaker 1: with colleague Werner Schmidler to write concerning moduli in non 254 00:14:50,800 --> 00:14:55,840 Speaker 1: commutative fields, particularly in differential and difference terms, and this 255 00:14:55,880 --> 00:15:00,840 Speaker 1: publication really established, like without question, Nurture as a mathematician 256 00:15:00,920 --> 00:15:03,480 Speaker 1: at the very top of her field. While the start 257 00:15:03,520 --> 00:15:05,880 Speaker 1: of World War One kept her from traveling to speak 258 00:15:05,880 --> 00:15:09,320 Speaker 1: at gatherings of mathematicians, starting in nineteen twenty she was 259 00:15:09,440 --> 00:15:13,720 Speaker 1: often on the road lecturing throughout Germany, and from ninety 260 00:15:13,800 --> 00:15:17,160 Speaker 1: and nineteen twenty six Nurture's work focused on what's called 261 00:15:17,200 --> 00:15:20,480 Speaker 1: the general theory of ideals, no more commonly in modern 262 00:15:20,560 --> 00:15:24,600 Speaker 1: times as commutative algebra. Her work during this time united 263 00:15:24,640 --> 00:15:27,680 Speaker 1: a lot of different mathematical concepts, but this was in 264 00:15:27,800 --> 00:15:30,000 Speaker 1: terms of her personal life a period of ups and 265 00:15:30,040 --> 00:15:33,760 Speaker 1: downs for Emmy. In one, for example, her father died, 266 00:15:33,840 --> 00:15:35,800 Speaker 1: so at this point she was left without both of 267 00:15:35,840 --> 00:15:39,240 Speaker 1: her father figure mentors in mathematics, and in the middle 268 00:15:39,240 --> 00:15:41,040 Speaker 1: of all that work, as we said, she was given 269 00:15:41,040 --> 00:15:45,240 Speaker 1: a lecture ship specifically in algebra in ninety three. Just 270 00:15:45,360 --> 00:15:48,240 Speaker 1: two years later, and he's first student to complete a 271 00:15:48,280 --> 00:15:52,560 Speaker 1: doctorate under her mentorship received her PhD. Emmy had mentored 272 00:15:52,600 --> 00:15:56,920 Speaker 1: another woman, Greta Herman, through her thesis process and Herman 273 00:15:57,000 --> 00:16:01,880 Speaker 1: finished her doctorate in February nine, twenty five. Around nineteen 274 00:16:01,920 --> 00:16:06,240 Speaker 1: twenty four, while she was working with Greta Herman and 275 00:16:06,480 --> 00:16:09,760 Speaker 1: lecturing and doing her research, Nurture was at the center 276 00:16:09,800 --> 00:16:13,480 Speaker 1: of this sort of interesting walking and talking phenomenon on campus. 277 00:16:14,400 --> 00:16:17,360 Speaker 1: Students and scholars alike would take long walks with Emmy 278 00:16:17,440 --> 00:16:21,160 Speaker 1: around the school of grounds, talking about what else mathematics 279 00:16:21,160 --> 00:16:25,000 Speaker 1: and math theory, and this informal group, which came to 280 00:16:25,000 --> 00:16:29,120 Speaker 1: be known as Nurtures Boys, included Russian scholar Pavel Alexandrov, 281 00:16:29,720 --> 00:16:32,200 Speaker 1: who was a visiting professor from the University of Moscow. 282 00:16:33,000 --> 00:16:37,000 Speaker 1: Nutter and Alexandrov became friends, and she was eventually invited 283 00:16:37,040 --> 00:16:41,480 Speaker 1: to Moscow as a guest lecturer in the nine academic year. 284 00:16:42,160 --> 00:16:46,040 Speaker 1: This was not the only international recognitions she was receiving 285 00:16:46,120 --> 00:16:49,000 Speaker 1: during this time, though. She also delivered a paper at 286 00:16:49,000 --> 00:16:53,560 Speaker 1: the International Mathematical Congress in Bologna, Italy that was in 287 00:16:53,680 --> 00:16:57,080 Speaker 1: nine and then a few years later in nineteen thirty two, 288 00:16:57,120 --> 00:17:01,360 Speaker 1: she addressed the same group in Zurich. In nine seven, 289 00:17:01,520 --> 00:17:06,120 Speaker 1: nursers focus shifted almost exclusively to noncommutative algebras, and these 290 00:17:06,119 --> 00:17:08,679 Speaker 1: are algebras where the order in which the numbers are 291 00:17:08,760 --> 00:17:11,840 Speaker 1: multiplied affects the outcome and nur There's work in this 292 00:17:11,920 --> 00:17:15,240 Speaker 1: area yielded a theory that enabled a conceptual unification of 293 00:17:15,320 --> 00:17:18,200 Speaker 1: all of them, and during her work in this phase 294 00:17:18,200 --> 00:17:21,320 Speaker 1: of her career, she collaborated with Helmet Hass and Richard 295 00:17:21,320 --> 00:17:24,800 Speaker 1: Brauer and published papers hyper Complex Number Systems and their 296 00:17:24,800 --> 00:17:30,200 Speaker 1: Representation in nine and non Commutative Algebra in nineteen thirty three. 297 00:17:30,880 --> 00:17:33,960 Speaker 1: From nineteen thirty to nineteen thirty three she also worked 298 00:17:34,000 --> 00:17:38,080 Speaker 1: as an editor on the German Mathematical Annual. Throughout all 299 00:17:38,080 --> 00:17:41,000 Speaker 1: of her research, writing and editing, she was also still 300 00:17:41,040 --> 00:17:44,480 Speaker 1: teaching regularly, but even so she was still employed at 301 00:17:44,520 --> 00:17:49,440 Speaker 1: a level far below what her colleagues thought she deserves. Yeah, 302 00:17:49,560 --> 00:17:52,520 Speaker 1: even as male mathematicians were rising up through the ranks 303 00:17:52,600 --> 00:17:55,880 Speaker 1: in the Gutting gutting in educational system at a rate 304 00:17:55,920 --> 00:18:00,000 Speaker 1: that really easily outpaced Emmy, they were so hugely influenced 305 00:18:00,040 --> 00:18:02,320 Speaker 1: by her work that many of them tried to point 306 00:18:02,359 --> 00:18:05,560 Speaker 1: out how wrong this was and tried to petition for 307 00:18:05,600 --> 00:18:09,119 Speaker 1: an improved title on her behalf. It generally came to 308 00:18:09,200 --> 00:18:11,800 Speaker 1: not with the greater university system, but in terms of 309 00:18:11,800 --> 00:18:14,600 Speaker 1: the mathematics world. She was regarded not just as a peer, 310 00:18:14,640 --> 00:18:17,879 Speaker 1: but as a leader. At this point, n three would 311 00:18:17,880 --> 00:18:20,800 Speaker 1: prove to be a pivotal year for Nurture, and we're 312 00:18:20,800 --> 00:18:23,040 Speaker 1: going to talk about it after we paused to chat 313 00:18:23,040 --> 00:18:26,119 Speaker 1: about one of our awesome sponsors who keep our show going. 314 00:18:34,520 --> 00:18:38,760 Speaker 1: In ninety three, Germany changed, obviously pretty significantly when the 315 00:18:38,840 --> 00:18:42,240 Speaker 1: Nazi Party came into power. Emmy Nurture, who was Jewish, 316 00:18:42,480 --> 00:18:45,760 Speaker 1: lost her job, as did many of her colleagues. The 317 00:18:45,880 --> 00:18:48,439 Speaker 1: Nazi Party had actually passed a number of laws that 318 00:18:48,480 --> 00:18:51,000 Speaker 1: were intended to keep Jews out of civil service jobs, 319 00:18:51,040 --> 00:18:55,119 Speaker 1: and that included academics. For a while, Emmy gave informal 320 00:18:55,920 --> 00:18:59,120 Speaker 1: lectures at her home, and she certainly had students who 321 00:18:59,119 --> 00:19:02,480 Speaker 1: were eager to continue learning from her. She was apparently 322 00:19:02,480 --> 00:19:04,879 Speaker 1: not even bothered when a student or two showed up 323 00:19:04,880 --> 00:19:09,160 Speaker 1: in their Nazi uniforms. She just wanted to talk about math. Meanwhile, 324 00:19:09,280 --> 00:19:12,320 Speaker 1: her friend Pablo Alexandrov was working to get the University 325 00:19:12,320 --> 00:19:15,919 Speaker 1: of Moscow to appoint her to a position, and his 326 00:19:16,000 --> 00:19:20,040 Speaker 1: efforts were really passionate, but they were getting slow response, 327 00:19:20,400 --> 00:19:22,639 Speaker 1: and finally Emmy just had to make a decision about 328 00:19:22,640 --> 00:19:26,360 Speaker 1: her future. As tensions mounted in Germany, she left Germany 329 00:19:26,440 --> 00:19:30,440 Speaker 1: in October to move to the United States. She'd been 330 00:19:30,440 --> 00:19:34,080 Speaker 1: offered a one year guest professor spot at brent Mark College. 331 00:19:34,560 --> 00:19:38,080 Speaker 1: Unbeknownst to Nurture, when she accepted the offer, the school 332 00:19:38,119 --> 00:19:40,920 Speaker 1: was also setting up a graduate fellowship in her name 333 00:19:41,000 --> 00:19:43,720 Speaker 1: for the academic year she would be teaching there. She 334 00:19:43,800 --> 00:19:46,600 Speaker 1: also lectured and worked on her math research in Princeton, 335 00:19:46,600 --> 00:19:50,280 Speaker 1: New Jersey, at the Institute for Advanced Study, and while 336 00:19:50,359 --> 00:19:53,160 Speaker 1: interest in her lectures was initially slow to catch on, 337 00:19:53,800 --> 00:19:56,760 Speaker 1: eventually Emmy did get a following of students, and she 338 00:19:56,840 --> 00:19:59,399 Speaker 1: sort of found this mirror group to the Nurture Boys 339 00:19:59,440 --> 00:20:02,560 Speaker 1: of gut In, but this group was called the Nurture Girls, 340 00:20:02,680 --> 00:20:05,960 Speaker 1: and they would go on hikes on Saturdays all the while, 341 00:20:06,080 --> 00:20:09,520 Speaker 1: just as she had in Germany, discussing mathematical concepts. Her 342 00:20:09,600 --> 00:20:12,439 Speaker 1: one year invitation to teach at bren Mar was extended 343 00:20:12,480 --> 00:20:16,359 Speaker 1: the following academic year of nineteen thirty five, but before 344 00:20:16,359 --> 00:20:18,679 Speaker 1: it started, she went back to Germany to visit her 345 00:20:18,720 --> 00:20:21,880 Speaker 1: brother Fritz and his family before they moved to Siberia 346 00:20:21,960 --> 00:20:25,359 Speaker 1: for a teaching position there. Like Emmy, Fritz lost his 347 00:20:25,440 --> 00:20:28,320 Speaker 1: job at the Institute of Technology under the Nazi government. 348 00:20:29,000 --> 00:20:31,719 Speaker 1: Emmy also visited her old campus and her friends at 349 00:20:31,760 --> 00:20:34,560 Speaker 1: gutting In, but she soon headed back to Pennsylvania for 350 00:20:34,600 --> 00:20:37,520 Speaker 1: another year at Bryn Mar and during her second year 351 00:20:37,520 --> 00:20:41,080 Speaker 1: there she mentored her first American PhD candidate, a young 352 00:20:41,119 --> 00:20:45,040 Speaker 1: woman named Ruth Halfer. The life of Emmy Nore ends 353 00:20:45,160 --> 00:20:48,320 Speaker 1: rather abruptly. In the spring of nineteen thirty five. She 354 00:20:48,400 --> 00:20:51,280 Speaker 1: went into the hospital to have an ovarian sister moved, 355 00:20:51,720 --> 00:20:55,040 Speaker 1: and while she seemed to be recovering well initially, she 356 00:20:55,200 --> 00:20:58,760 Speaker 1: died quite suddenly on April fourteenth, four days after her surgery. 357 00:20:59,640 --> 00:21:02,760 Speaker 1: Just a weeks later, on May third, of the New 358 00:21:02,840 --> 00:21:05,280 Speaker 1: York Times ran a letter that was written by Albert 359 00:21:05,280 --> 00:21:09,040 Speaker 1: Einstein about Emmy Nutter, and he wrote, within the past 360 00:21:09,080 --> 00:21:13,120 Speaker 1: few days, a distinguished mathematician, professor I mean Notre, formerly 361 00:21:13,160 --> 00:21:16,040 Speaker 1: connected with the University of Guttingen and for the past 362 00:21:16,160 --> 00:21:19,520 Speaker 1: two years at Renmark College, died in her fifty third year, 363 00:21:20,119 --> 00:21:23,920 Speaker 1: and the judgment of the most competent living mathematicians, Fraeulein 364 00:21:24,080 --> 00:21:27,920 Speaker 1: Notre was the most significant creative mathematical genius thus bar 365 00:21:28,040 --> 00:21:31,720 Speaker 1: produced since the higher education of women began in the 366 00:21:31,760 --> 00:21:34,720 Speaker 1: realm of algebra, in which the most gifted mathematicians have 367 00:21:34,800 --> 00:21:38,920 Speaker 1: been busy for centuries. She discovered methods which have proved 368 00:21:39,320 --> 00:21:43,040 Speaker 1: of enormous importance in the development of the present day 369 00:21:43,080 --> 00:21:48,520 Speaker 1: younger generation of mathematicians. And now while we have reached 370 00:21:48,520 --> 00:21:50,800 Speaker 1: the point in emmy story where she has departed this 371 00:21:50,880 --> 00:21:53,879 Speaker 1: earthly plane, there's a little bit more to talk about 372 00:21:53,880 --> 00:21:56,280 Speaker 1: in terms of her politics. And the reason that we're 373 00:21:56,320 --> 00:21:59,720 Speaker 1: putting that this at the end is because the primary 374 00:21:59,720 --> 00:22:03,480 Speaker 1: infra nation we have about it isn't from things that 375 00:22:03,600 --> 00:22:06,879 Speaker 1: came up in her actual lifetime or again her writings, 376 00:22:06,880 --> 00:22:09,399 Speaker 1: which we don't have. It's stuff that came up in 377 00:22:09,440 --> 00:22:13,320 Speaker 1: eulogies and memorials from colleagues after her death, specifically two 378 00:22:13,320 --> 00:22:17,320 Speaker 1: of them. In nineteen nineteen, Nature joined the independent Social 379 00:22:17,359 --> 00:22:20,359 Speaker 1: Democrats group and getting in and to some the group 380 00:22:20,440 --> 00:22:24,159 Speaker 1: was considered an extremely radical Bolshevik group. It was a 381 00:22:24,200 --> 00:22:27,080 Speaker 1: splinter group that broke away from the Social Democratic Party 382 00:22:27,119 --> 00:22:30,280 Speaker 1: in nineteen fourteen as a centrist group between the Social 383 00:22:30,280 --> 00:22:34,160 Speaker 1: Democratic Party and the Communist Party of Germany. But two 384 00:22:34,200 --> 00:22:37,959 Speaker 1: of her close friends and fellow mathematicians interpret her politics 385 00:22:38,240 --> 00:22:42,679 Speaker 1: very differently. When they spoke about her life. First Herman 386 00:22:42,760 --> 00:22:47,159 Speaker 1: Wile while worked in analysis, number theory, foundational mathematics and 387 00:22:47,240 --> 00:22:52,320 Speaker 1: quantum mechanics, among other areas, and he met Nature in 388 00:22:52,840 --> 00:22:55,480 Speaker 1: gutting In in nineteen thirteen, and they remained quite close 389 00:22:55,520 --> 00:22:58,560 Speaker 1: throughout the rest of Emmy's life. And when while spoke 390 00:22:58,600 --> 00:23:00,879 Speaker 1: of Emmy's political stance, it was very much in the 391 00:23:00,920 --> 00:23:03,240 Speaker 1: vein that she was a pacifist and she definitely was, 392 00:23:03,320 --> 00:23:06,959 Speaker 1: we know that with great hopes for Germany's future, and 393 00:23:06,960 --> 00:23:10,119 Speaker 1: that really she saw the independent Social Democrats as the 394 00:23:10,160 --> 00:23:13,080 Speaker 1: next stage of the Social Democrats, not as a radical shift, 395 00:23:13,160 --> 00:23:16,280 Speaker 1: but as a gradual evolution. And he also wrote of 396 00:23:16,320 --> 00:23:19,480 Speaker 1: Emmy that quote, without being actually in party life, she 397 00:23:19,560 --> 00:23:23,080 Speaker 1: participated intensely in the discussion of the social and political 398 00:23:23,080 --> 00:23:26,600 Speaker 1: problems of the day. On the other hand, Pavel Alexandrov 399 00:23:27,119 --> 00:23:30,840 Speaker 1: characterized Emmy as very pro Soviet. He said that quote, 400 00:23:30,880 --> 00:23:34,080 Speaker 1: she always had a lively interest in politics and hated 401 00:23:34,200 --> 00:23:37,320 Speaker 1: war and chauvinism in all its forms, and with her 402 00:23:37,359 --> 00:23:42,080 Speaker 1: whole being, her sympathies were always unwaveringly with the Soviet Union. 403 00:23:42,880 --> 00:23:45,320 Speaker 1: So it seems based on the fact that Alexandrov was 404 00:23:45,359 --> 00:23:47,919 Speaker 1: working to get Emmy a position in Moscow in nineteen 405 00:23:48,000 --> 00:23:50,439 Speaker 1: thirty three, that she was comfortable with the idea of 406 00:23:50,520 --> 00:23:53,880 Speaker 1: living in the Soviet Union, and the Bolshevik Revolution took 407 00:23:53,920 --> 00:23:56,680 Speaker 1: place while she was working in academia, so it's really 408 00:23:56,760 --> 00:23:59,880 Speaker 1: unlikely that she was blind or ignorant to the political 409 00:24:00,000 --> 00:24:03,080 Speaker 1: events that were playing out around her. But since both 410 00:24:03,119 --> 00:24:06,479 Speaker 1: of these men likely saw Emmy's political stance through their 411 00:24:06,520 --> 00:24:08,840 Speaker 1: own lenses and in the way they wished to see her, 412 00:24:08,920 --> 00:24:10,520 Speaker 1: and since we do not have any of her own 413 00:24:10,520 --> 00:24:14,000 Speaker 1: writing on the subject to reference, we really don't know 414 00:24:14,040 --> 00:24:17,919 Speaker 1: where she truly stood. What's really indisputable as that I 415 00:24:17,960 --> 00:24:20,800 Speaker 1: mean notre was a major figure in mathematics, both in 416 00:24:20,800 --> 00:24:23,840 Speaker 1: her time and today, as many others have built upon 417 00:24:23,880 --> 00:24:27,880 Speaker 1: her work, and she seems simply unflappable in the face 418 00:24:27,920 --> 00:24:30,400 Speaker 1: of the difficulties she faced as she made a name 419 00:24:30,440 --> 00:24:33,000 Speaker 1: for herself in a field that had very few women 420 00:24:33,000 --> 00:24:35,119 Speaker 1: in it. And so I wanted to end with a 421 00:24:35,200 --> 00:24:38,359 Speaker 1: quote from her friend Pavel Alexandrov, because it describes Emmy 422 00:24:38,400 --> 00:24:40,280 Speaker 1: in such a way that I think anybody would want 423 00:24:40,320 --> 00:24:43,600 Speaker 1: to know her. It says, quote her great sense of humor, 424 00:24:43,640 --> 00:24:46,879 Speaker 1: which made social gatherings in personal contacts with her so 425 00:24:47,040 --> 00:24:50,560 Speaker 1: pleasant enabled her to counter the injustices and absurdities that 426 00:24:50,600 --> 00:24:55,200 Speaker 1: beset her academic career easily and without anger. In such circumstances, 427 00:24:55,200 --> 00:24:58,320 Speaker 1: instead of being offended, she would simply laugh. But she 428 00:24:58,480 --> 00:25:01,840 Speaker 1: was very offended indeed, in protested sharply when even the 429 00:25:01,880 --> 00:25:05,760 Speaker 1: smallest injustice was directed at one of her students. I 430 00:25:05,840 --> 00:25:11,960 Speaker 1: love that quote. Um, there's really no substantiation in any way, 431 00:25:12,000 --> 00:25:15,240 Speaker 1: but there are. It will come up as theory sometimes 432 00:25:15,240 --> 00:25:19,240 Speaker 1: that she was connected romantically to either While or Alexandrov, 433 00:25:19,280 --> 00:25:21,119 Speaker 1: although we don't know, and none of them, none of 434 00:25:21,119 --> 00:25:23,320 Speaker 1: their letters ever hinted any of that, so we just 435 00:25:23,359 --> 00:25:24,840 Speaker 1: have no idea. But we do know that she was 436 00:25:24,920 --> 00:25:27,160 Speaker 1: very close with both of those men. So I love 437 00:25:27,240 --> 00:25:30,480 Speaker 1: that that sort of lovely description of her. Yeah. Um, 438 00:25:30,520 --> 00:25:32,880 Speaker 1: And now we'll get to the listener mail and inspired 439 00:25:32,920 --> 00:25:34,760 Speaker 1: this whole thing. And this is from our listener, Mark, 440 00:25:34,920 --> 00:25:38,000 Speaker 1: who is amazing, and he writes, Hi, Holly and Tracy, 441 00:25:38,160 --> 00:25:40,119 Speaker 1: I enjoyed listening to your podcast, and I thought you 442 00:25:40,200 --> 00:25:42,920 Speaker 1: might like a laser engraving of one of my favorite mathematicians, 443 00:25:42,960 --> 00:25:46,640 Speaker 1: Emmy Nurture. I did the engraving on one millimeter aircraft Plywood, 444 00:25:46,680 --> 00:25:48,520 Speaker 1: hoping that would make it a little more unique. I 445 00:25:48,560 --> 00:25:50,359 Speaker 1: listened to your podcast when I'm on the road or 446 00:25:50,400 --> 00:25:53,359 Speaker 1: in the lab a guitar lab. Really keep up your 447 00:25:53,359 --> 00:25:57,160 Speaker 1: great work. And Mark sent us this absolutely beautiful engraving 448 00:25:57,400 --> 00:25:59,679 Speaker 1: of Emmy and I just was so struck by it 449 00:25:59,720 --> 00:26:01,880 Speaker 1: that we had to do an episode. Yeah, and we're 450 00:26:01,880 --> 00:26:04,600 Speaker 1: going to post a picture of it. It's great and 451 00:26:05,320 --> 00:26:07,760 Speaker 1: it's uh So we've talked about how I don't normally 452 00:26:07,800 --> 00:26:09,959 Speaker 1: work in the same office as Holly anymore, and so 453 00:26:10,040 --> 00:26:13,160 Speaker 1: Holly will send me pictures of the things that come 454 00:26:13,160 --> 00:26:15,479 Speaker 1: into the office and are amazing. And that was whe 455 00:26:15,480 --> 00:26:18,760 Speaker 1: where I kept zooming in on my phone usually text 456 00:26:18,760 --> 00:26:22,080 Speaker 1: Gorget like WHOA, what's happening. It's really it's very beautiful. 457 00:26:22,160 --> 00:26:24,119 Speaker 1: I love it. Mark, thank you so much. That was 458 00:26:24,200 --> 00:26:27,160 Speaker 1: so thoughtful and cool, and I appreciate that you took 459 00:26:27,200 --> 00:26:29,479 Speaker 1: time to make us a really famulous gift. We're very, 460 00:26:29,560 --> 00:26:38,000 Speaker 1: very lucky. Thank you so much for joining us on 461 00:26:38,040 --> 00:26:41,399 Speaker 1: this Saturday.
