Eigenvectors and Eigenvalues (2015)
Whenever this kind of stuff comes up I feel like a bit of a fraud...I’ve written a bunch of scientific data analysis code. I have a science PhD. Written large image analysis pipelines that worked as well as the state of the art... been published etc.For the most part I’ve found basic math and heuristics to be good enough. Every so often I go relearn calculus. But honestly, none of this stuff ever seems to come in handy. Maybe it’s because most of what I encounter is novel datasets where there’s no established method?I reasonably regularly pick up new discrete methods, but the numerical stuff never seems super useful...I don’t know, just a confession I guess... it never comes up on interviews either for what it’s worth.
