The general public is interested in female contributions to science on the whole. And they would appreciate knowing about Noether. And the physics community by an large does know her.
But that information has not escaped the relatively esoteric setting of physics education.
On top of that I'd be curious how many of those who know of the symmetry conservation link, know of it as Noether's theorem and how many know Noether was a woman. I bet not much! Just speculation.
Again that would be hiding in plain sight in my book.
At the time I wouldn’t have cared anyway. I was bombarded with so many names of people through equations, experiments, etc that I didn’t care if they were a man, woman, or carrier pigeon. I just cared what the result meant and how I could use it. It’s only after the fact, long after I left academia, that I started to see these people as humans with real lives and stories.
It’s OK if mathematicians are obscure in the general population. That’s part of the deal when you become a mathematician. I don’t know many footballers either.
I would much rather the general public filled their heads with basic mathematical concepts, rather than the names of mathematicians. As Feynman said (paraphrasing), knowing the name of something is rather useless if you don’t know anything else about it.
If you’re talking about the general public, then she is under appreciated but so is pretty much every other physicist too.
