Why did emmy noether die

She spent her time in school studying languages, with a concentration on French and English. Her mother taught her the traditional skills of a young woman of that time. She learned to cook, clean, and play the clavier.

At the time of her graduation from high school, she passed a test that allowed her to teach both French and English at schools for young women. At the age of 18, Emmy Noether decided to take classes in mathematics at the University of Erlangen. Her brother, Fritz, was a student there, and her father was a professor of mathematics. Because she was a woman, the university refused to let Emmy Noether take classes They granted her permission to audit classes.

She sat in on classes for two years, and then took the exam that would permit her to be a doctoral student in mathematics. She passed the test, and finally was a student in good standing at the University. After five more years of study, she was granted the second degree to a woman in the field of mathematics. The first graduated a year earlier. Now that Emmy Noether had her doctorate in mathematics, she was ready to find a job teaching.

The University of Erlangen would not hire her, as they had a policy against women professors. She decided to help her father at the Mathematics Institute in Erlangen. She began doing research there, and helped her father by teaching his classes when he was sick. Soon, she began to publish papers on her work. Emmy was a pacifist at heart, and hated the war. She longed for a Germany that was not at war. In , her wish was granted, as the war ended. The German monarchy was removed and the country became a republic.

Noether, and all women in Germany, were given the right to vote for the first time. Even with the new rights granted to women, Noether was not paid for her work teaching. During this time, Felix Klein and David Hilbert were working on further defining one of Einstein's theories at the University of Gottingen. They felt that Emmy Noether's expertise could help them in their work. They asked her to come and join then, but since there were no women on the faculty, Noether was unsure if she would be welcome.

Many of the faculty did not want her there, but in the end, she came. She worked hard and soon was given a job as a lecturer. Even though she still was not paid for her efforts, for the first time, Noether was teaching under her own name. Three years later, she began receiving a small salary for her work. During her time at the University of Gottingen, she accumulated a small following of students known as Noether's boys.

The oral examination took place on Friday 13 December and she was awarded the degree 'summa cum laude'. Hilbert 's basis theorem of had given an existence result for finiteness of invariants in n n n variables. Gordan , however, took a constructive approach and looked at constructive methods to arrive at the same results. Noether's doctoral thesis followed this constructive approach of Gordan and listed systems of covariant forms.

Colin McLarty writes that [ 39 ] So far as I know no one has ever completed it or even checked it as far as she went. It was old-fashioned at the time, a witness to the pleasant isolation of Erlangen, and made no use of Gordan 's own work building on Hilbert 's ideas.

Having completed her doctorate the normal progression to an academic post would have been the habilitation. However this route was not open to women so Noether remained at Erlangen, helping her father who, particularly because of his own disabilities, was grateful for his daughter's help.

Noether also worked on her own research, in particular she was influenced by Ernst Fischer who had succeeded Gordan to the chair of mathematics when he retired in Noether wrote about Fischer 's influence:- Above all I am indebted to Mr E Fischer from whom I received the decisive impulse to study abstract algebra from an arithmetical viewpoint, and this remained the governing idea for all my later work. Fischer 's influence took Noether towards Hilbert 's abstract approach to the subject and away from the constructive approach of Gordan.

Now this was very important to her development as a mathematician for Gordan , despite his remarkable achievements, had his limitations. Noether's father, Max Noether , said of Gordan see [ 3 ] :- Gordan was never able to do justice to the development of fundamental concepts; even in his lectures he completely avoided all basic definitions of a conceptual nature, even that of the limit. Noether's reputation grew quickly as her publications appeared.

In she was elected to the Circolo Matematico di Palermo , then in she was invited to become a member of the Deutsche Mathematiker-Vereinigung and in the same year she was invited to address the annual meeting of the Society in Salzburg.

In she lectured in Vienna, again to a meeting of the Deutsche Mathematiker-Vereinigung. While in Vienna she visited Franz Mertens and discussed mathematics with him. One of Merten's grandsons remembered Noether's visit see [ 5 ] During these years in Erlangen she advised two doctoral students who were both officially supervised by her father.

These were Hans Falckenberg doctorate and Fritz Seidelmann doctorate For information on these and Noether's other Ph. The reason for this was that Hilbert was working on physics, in particular on ideas on the theory of relativity close to those of Albert Einstein. He decided that he needed the help of an expert on invariant theory and, after discussions with Klein , they issued the invitation. Van der Waerden writes [ 68 ] :- She came and at once solved two important problems.

First: How can one obtain all differential covariants of any vector or tensor field in a Riemannian space? The second problem Emmy investigated was a problem from special relativity. She proved: To every infinitesimal transformation of the Lorentz group there corresponds a Conservation Theorem. This result in theoretical physics is sometimes referred to as Noether's Theorem, and proves a relationship between symmetries in physics and conservation principles.

This basic result in the theory of relativity was praised by Einstein in a letter to Hilbert when he referred to Noether's penetrating mathematical thinking. This was a time of extreme difficulty and she lived in poverty during these years and politically she became a radical socialist.

However, they were extraordinarily rich years for her mathematically. Hermann Weyl , in [ 69 ] writes about Noether's political views:- During the wild times after the Revolution of , she did not keep aloof from the political excitement, she sided more or less with the Social Democrats; without being actually in party life she participated intensely in the discussion of the political and social problems of the day. In later years Emmy Noether took no part in matters political.

She always remained, however, a convinced pacifist, a stand which she held very important and serious. In a long battle with the university authorities to allow Noether to obtain her habilitation there were many setbacks and it was not until that permission was granted and she was given the position of Privatdozent.

During this time Hilbert had allowed Noether to lecture by advertising her courses under his own name. For example a course given in the winter semester of - 17 appears in the catalogue as:- Mathematical Physics Seminar: Professor Hilbert , with the assistance of Dr E Noether, Mondays from 4 - 6 , no tuition. In this paper she gave the decomposition of ideals into intersections of primary ideals in any commutative ring with ascending chain condition.

Emanuel Lasker who became the world chess champion had already proved this result for a polynomial ring over a field. In this paper she gave five conditions on a ring which allowed her to deduce that in such commutative rings every ideal is the unique product of prime ideals.

The major part of the second volume consists of Noether's work. From onwards Noether collaborated with Helmut Hasse and Richard Brauer in work on non-commutative algebras. In addition to teaching and research, Noether helped edit Mathematische Annalen. Much of her work appears in papers written by colleagues and students, rather than under her own name.

She received no pension or any other form of compensation but, nevertheless, she considered herself more fortunate than others.

She wrote to Helmut Hasse on 10 May see for example [ 5 ] :- Many thanks for your dear compassionate letter! I must say, though, that this thing is much less terrible for me than it is for many others. At least I have a small inheritance I was never entitled to a pension anyway which allows me to sit back for a while and see. Weyl spoke about Noether's reaction to the dire events that were taking place around her in the address he gave at her funeral:- You did not believe in evil, indeed it never occurred to you that it could play a role in the affairs of man.

In the midst of the terrible struggle, destruction and upheaval that was going on around us in all factions, in a sea of hate and violence, of fear and desperation and dejection - you went your own way, pondering the challenges of mathematics with the same industriousness as before. Her writing, the students she inspired, and their books wholly changed the form and content of higher algebra throughout the world.

Noether was born in Erlangen, Germany, on March 23, Her father, Max Noether, was a professor of mathematics at Erlangen, an expert on algebraic geometry. She received her Ph. There, she gave a course in his name she was not allowed to lecture at the time on her own account and applied her knowledge of invariant theory to relativity theory in a paper that impressed Einstein. In , she turned her attention to algebra, with decisive axiomatic treatment of the theory of ideals as they apply to number theory to factor algebraic integers and to algebraic geometry curves and surfaces defined by equations.

She inspired many students, in particular the Dutchman B. Van der Waerden, who delivered brilliant lectures following her ideas and then presented them in his famous text Modern Algebra , which revolutionized the subject.

In , Garrett Birkhoff and Saunders Mac Lane published an undergraduate text, Survey of Modern Algebra , which introduced the Noether view of mathematics to English-speaking students.

Her own research with Brauer and Hasse in solved a famous problem in the theory of algebras. The Rockefeller Foundation helped to fund a position for her in the United States at Bryn Mawr College, where there was a long tradition of interest in higher mathematical research. There she was also able to travel once a week to Princeton University, to lecture there and at the Institute for Advanced Study, giving her effective access to one of the great centers of American mathematics.

At Bryn Mawr, she helped various young women mathematicians. She advised Marie J. Weiss and guided the Ph.

Emmy Noether died on April 14, , from complications following surgery. Her ideas about the abstract and conceptual approach of mathematics have been spread throughout the mathematics world by her students, her admirers, and many others who had personal contact with her. In the judgment of many, she is the greatest algebraist of the twentieth century.
