<i>I am often told that I should keep my nose out of other science domain's business because they know more than I do.</i><p>I've only heard such statements coming out of a few fields: math education, labor economics, climate science and psychometrics of race/gender. You should ignore such statements; they are nothing more than an attempt to bully you into accepting received wisdom from activists with a PhD.<p>As an actual scientist (rather than a political activist with a PhD), I strongly encourage you to stick your nose into any or all of my fields (quantum mechanics, PDEs, medical imaging, complex analysis, prediction markets). If you come up with dumb ideas, I'll even explain why they are dumb, rather than just demanding that you leave things to the experts.
