    Noether is one of my heroes. Rising through the ranks to one of the greatest minds we've known, recognized in spite of being a woman in a time where that was unthinkable in science, all odds against her. And yet here she is, the name of one of the most basic, and most beautiful, concepts in physics. The inventor of abstract algebra too (which I hear is as significant, it's just not my domain).

    So many great minds have had to fight an uphill battle, but few had it as steep and even fewer were as successful as her doing so.

    It really is a shame that she's not as recognized as the Bohrs and Feynmans and Paulis and so on, but at least everyone with a passing interest in theoretical physics ought to know about her.

    I wish invariant theory was taught outside of physics and maths departments. Engineers are missing out.

      As an engineer, this and the principle of least action occupy my wall of “things I think are super deep and maybe mysterious* and interesting and I wish I understood deeply”

      A much restricted case is/(used to be) taught to computer vision students. It's needed to generate features that are invariant to shift, rotation and scaling.
