Home > Emmy Noether


Emmy Noether ( March 23 1882April 14 1935) was one of the most talented mathematicians of the early 20th century, with penetrating insights that she used to develop elegant abstractions which she formalized beautifully.


She was born Amalie Noether in Erlangen, Bavaria, Germany. Her father, Max Noether , was a distinguished mathematician and a professor at Erlangen. She did not show any early precocity at mathematics — as a teenager she was more interested in music and dancing.

She received her doctorate in 1907 and rapidly built a world-wide reputation, but the University of Göttingen refused to let her teach, and her colleague, David Hilbert, had to advertise her courses in the university's prospectus under his own name. A long controversy ensued, with her opponents asking what the country's soldiers would think when they returned home and were expected to learn at the feet of a woman. Allowing her on the faculty would also mean letting her vote in the academic senate. Said Hilbert, "I do not see that the sex of the candidate is against her admission as a Privatdozent. After all, the university senate is not a bathhouse." She was finally admitted to the faculty in 1919. A Jew, Noether was forced to flee Nazi Germany in 1933Centuries: 19th century 20th century 21st century Decades: 1880s 1890s 1900s 1910s 1920s 1930s 1940s 1950s 1960s 1970s 1980s Years: 1928 1929 1930 1931 1932 1933 1934 1935 1936 1937 1938 See also 1933 in aviation 1933 in film 1933 in literature 1933 in mu and joined the faculty at Bryn Mawr in the United StatesThe United States of America also referred to as the United States U.

She made very significant contributions to mathematics and theoretical physicsPhysics (from the Greek, physikos , "natural", and physis , "Nature") is the science of Nature in the broadest sense. Physicists study the behavior and properties of matter in a wide variety of contexts, ranging from the sub-microscopic particles from whi. In mathematics, she worked on the theory of invariantsIn mathematics, invariant theory refers to the study of invariant algebraic forms (equivalently, symmetric tensors) for the action of linear transformations. This was a major field of study in the latter part of the nineteenth century, when it appeared th and non-commutative algebrasIn mathematics, ring theory is the study of rings, algebraic structures in which addition and multiplication are defined and have similar properties to those familiar from the integers. Please refer to the glossary of ring theory for the definitions of te. In physics, she arrived at a very crucial and beautiful result known as Noether's theoremNoether's theorem is a central result in theoretical physics that expresses the equivalence of two different properties of physical laws for models based upon the action principle (i. there are models which aren't). It is named after the early 20th centur, which translated statements of invariance with respect to generalized transformations of physical systems, called symmetries by physicists, into conservation laws. The results of Noether's theorem are part of the fundamentals of modern physics, which is substantially based on the properties of symmetries.

In 1921, Noether introduced the ascending chain condition for ideals in a commutative ring, and proved the existence of primary decompositions for such rings (a result known as the Lasker-Noether theorem). Rings satisfying the ascending chain condition on ideals are now known as Noetherian rings.

She died at Bryn Mawr in 1935.
