Any tips for getting into semiconductors with bad grades? I'm looking to come out in the same situation as you but I have no idea what projects if any to do or if I should just focus on academic type questions like RLC circuits? Also how/where should I aim for an internship, I'm gonna be a super senior and I've only got tangentially related experience.

/sci/, I've been thinking about something. I've noticed that whenever I talk to physicists and physics students they always have an amazing grasp of the mathematics, but most seem completely and utterly unable to translate that understanding into something that's not an equation. When asked to describe it visually, they illustrate abstract properties rather than objects. When asked to explain in words, they repeat the equation but just spell out each operation and relation.

Obviously, a deep understanding of mathematics is critical to science – you simply can't do physics without it – but don't you think it's detrimental that so many of our physicists don't have a general enough understanding of their area of expertise to communicate it?

I'm sick of every explanation of quantum physics being either so simple it provides no information or so technical it's unreadable to someone who doesn't already understand it!

can someone please just spin to me in a way that's simple enough for someone with almost no higher education to understand, but still tells me most of what I need to know about how it works?

What's the particle-in-a-box equation for a case in which the "box" is the surface of a sphere?

how do theories with extra dimensions deal with spin?

wouldn't more dimensions mean more degrees of freedom for polarization and thus more spin states? What would it even look like if a particle was spinning in one of these compactified dimensions?

Could you have a standing wave pattern on the surface of a mobius strip? I can't tell if it would cancel itself out or not
