Eigenvectors and Eigenvalues (2015)
Whenever this kind of stuff comes up I feel like a bit of a fraud...<p>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.<p>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?<p>I reasonably regularly pick up new discrete methods, but the numerical stuff never seems super useful...<p>I don’t know, just a confession I guess... it never comes up on interviews either for what it’s worth.
