Emmy Noether was a brilliant mathematician whose work was integral to Albert Einstein’s development of the theory of general relativity.
In the early 1910s, Einstein’s general relativity theory had a significant flaw: it did not seem to account for the fundamental principle of the conservation of energy.
Mathematicians David Hilbert and Felix Klein invited Noether to the University of Göttingen in 1915 to lend her expertise in invariant theory to help resolve this issue.
Noether’s Theorem: It was there that Noether developed her groundbreaking Noether’s theorem, which solved the problem.
The theorem established a fundamental link between symmetries in nature and conservation laws (e.g., time symmetry results in the conservation of energy).
This theorem validated Einstein’s theory and has since become a cornerstone of modern physics, underpinning the Standard Model of particle physics.
Mutual Respect: Einstein and Noether corresponded, and Einstein expressed his “wonderment at what happened to his equations in her hands”. In a letter to Hilbert, he stated that it was “really through her that I have become competent in the subject”.
Einstein was a strong advocate for Noether. In a 1935 obituary for her published in The New York Times, he praised her genius and lamented the lack of recognition she received during her lifetime due to discrimination.
Wasn’t she played by Meg Ryan? ;-D
