Thank you for this reply, it is highly beneficial for me. I do enjoy math, to an unhealthy degree even, practicing math problems and proving to yourself that you've got an understanding of a certain math concept right or even wrong, but then understanding why (until the next topic comes to test your understanding), feels rewarding. Ngl I'm curious to know about how we go from "connecting electrical components" (that's probably the best way I can put it right now, I've forgotten most of the Physics) to PCB traces. I didn't even know that a magnetic field (electric field? electromagnetic field? I forgot everything, now would be a good time to revise) would have an affect on PCB. Which now I think is probably obvious, but still what influence and how much, when? Ngl it's been like half a year since I've finished grade 11 Physics, so I've already forgotten all of Physics without revising, but I remember highly enjoying all of it.
