A short thread on Emmy Noether and giving credit.
Felix Klein gave a lecture at the Mathematical Society of Göttingen #OTD in 1918. The title was “On Hilbert’s first note on the foundations of physics."
Klein included excerpts from letters in which he and Hilbert give priority to Emmy Noether for her results on conservation of energy in general relativity.
Noether’s contributions were not always appreciated, because some of them happened outside of formal publications, in consultation with more senior researchers, or without the fanfare of a well-known scientist announcing a result at a major meeting. (The proximate causes here were of course sexism and antisemitism.)
But her peers knew.
Klein was very clear in a letter to Hilbert:
"You know that Miss Noether advises me continually regarding my work, and that in fact it is only thanks to her that I have understood these questions.”
He explains how Noether obtained the result they are discussing a year earlier.
He goes on to say that he read her manuscript on the subject, and notes
"She simply did not set it out as forcefully as I recently did at the Mathematical Society.”
Klein is saying, as plainly as possible, that Noether established a result that is being credited to him.
Hilbert responds “I fully agree,” adding that he had also received help from Noether the previous year.
He closes his letter with a conjecture about the origin of energy conservation in general relativity, adding "It would be good to produce the mathematical proof."
You can probably guess what comes next.
In a reprint of his lectures, Klein notes that the proof was provided by Emmy Noether in her famous 1918 paper "Invariante Variationsprobleme," which appeared six months later.
Sometimes on the bird site I would get replies or DMs suggesting that Noether’s importance is overstated, a revisionist history meant to appease folks concerned with equality and social justice.
That's not correct. She did essential work before her colleagues but didn’t get credit until much, much later.
It’s easy enough to verify this. Hilbert and Klein couldn't have been more plain about it in their correspondence.
