The Noetherian Ring

Today marks the birthday of mathematician Emmy Noether (1882-1935).

As one of the leading mathematicians of her time, she advanced theories of rings, fields, and algebras. In the area of physics, Noether's theorem explores the connection between symmetry and conservation laws.

While studying at the University of Erlangen as just one of two women at the school, Noether was allowed only to audit classes and needed to obtain permission from her professors in order to attend. After passing her graduation exam, she taught at the school’s Mathematical Institute for seven years without pay, frequently covering her father’s classes when he was out sick while publishing her own papers.

Google created a tribute doodle for her illustrating her contributions in the area of topology (the donut and coffee mug), ascending/descending chains, Noetherian rings, time, group theory, conservation of angular momentum, and continuous symmetries.

Noether was generous with her ideas and is credited with several lines of research published by other mathematicians, even in fields far removed from her main work, such as algebraic topology.

See below for the dance cribs, dedicated to the Erlangen Scottish Country Dancers of 1999-2000.

The dance dedication reads, "This dance was written in honor of the mathematician Emmy Noether (born March 23, 1882 in Erlangen - died April 14, 1935 in Bryn Mawr), who loved to dance. She received her doctorate from the Mathematics Institute of Uni-Erlangen in 1907. The dance was inspired by the term Noetherian Ring, which is a mathematical ring where every ascending chain of ideals terminates."
