# Day 13 | LThMath Advent Calendar

I wanted to have at least one day dedicated to a mathematician. As no surprise to people that have been following me, I have chosen Emmy Noether. Emmy Noether means a lot to me and I have been fascinated by her work.

**Amalie Emmy Noether **(23 March 1882 – 14 April 1935) was a German mathematician who made many important contributions to abstract algebra. She discovered Noether's theorem, which is fundamental in mathematical physics. She was described by Pavel Alexandrov, Albert Einstein, Jean Dieudonné, Hermann Weyl and Norbert Wiener as the most important woman in the history of mathematics. As one of the leading mathematicians of her time, she developed some theories of rings, fields, and algebras. In physics, Noether's theorem explains the connection between symmetry and conservation laws.

Emmy Noether received her Ph. D. degree, summa cum laude, from the university of Erlangen, for a dissertation on algebraic invariants directed by Paul Gordon. She went on to become one of the world's greatest mathematicians.
