How This Woman Changed Physics

Emmy Noether may be obscure, but her work was revolutionary

(Newser) – Her work may be the "backbone" of all modern physics; her key theorem could be as important as the theory of relativity; yet hardly anyone knows who Emmy Noether is. Celebrating her 130th birthday this month, Noether has suffered what the New York Times calls "chronic neglect"—including in the physics community—even though she was celebrated by leading mathematicians of her day: Albert Einstein said she was the most "significant" female mathematician ever.

Born in Germany, Noether worked in an era when hardly any German universities accepted women; the rise of the Nazis later forced the Jewish mathematician to leave the country. But despite the odds, she scored a job as a guest lecturer and developed "Noether's theorem," which addresses connections among geometry, mass, and energy and explains why "riding a bicycle is safe." She ended up at Bryn Mawr College in Pennsylvania before dying at the age of 53. Click through for the full profile.

From Atomic Archive -Lise Meitner "Another rarely mentioned female luminary in nuclear physics was Lise Meitner , who was born on November 7, 1878, in Vienna, Austria. The third of eight children of a Jewish family, she entered the University of Vienna in 1901, studying physics under Ludwig Boltzmann. After she obtained her doctorate degree in 1906, she went to Berlin in 1907 to study with Max Planck and the chemist Otto Hahn. She worked together with Hahn for 30 years, each of them leading a section in Berlin's Kaiser Wilhelm Institute for Chemistry. Hahn and Meitner collaborated closely, studying radioactivity, with her knowledge of physics and his knowledge of chemistry. After Austria was annexed by Germany in 1938, Meitner was forced to flee Germany for Sweden. She continued her work at Manne Siegbahn's institute in Stockholm, but with little support, partially due to Siegbahn's prejudice against women in science. Hahn and Meitner met clandestinely in Copenhagen in November to plan a new round of experiments. The experiments that provided the evidence for nuclear fission were done at Hahn's laboratory in Berlin and published in January 1939. In February 1939, Meitner published the physical explanation for the observations and, with her nephew, physicist Otto Frisch, named the process nuclear fission. The discovery led other scientists to prompt Albert Einstein to write President Franklin D. Roosevelt a warning letter, which led to the Manhattan Project." Basically, Meitner's explanation of Otto Hahn's experiments showed that E-mc2 was true, and that energy had indeed been produced in the splitting of the atom, and this led directly to the race for the atomic bomb when Szilard, Wigner and Einstein sent that famous letter to FDR.

"why riding a bicycle is safe" yep that equals relativity, E=MC2   and merging electromagnetism, the strong and weak forces in a unified theory of time and space.  Just total sexism causing her to be ignored. yep yep sheesh
