In the process of learning about #HamRadio, I'm learning so much physics at a deeper level than I did when I studied it more formally in college. A great deal of context and relevant experience in the meantime is helping me out, I'm sure, but there are things I remember struggling with that I just ... get .... this time around. Like P-type and N-type semiconductors — I remember being frustrated with the concept when I first encountered it, but it feels so straightforward and clear now. I can only hypothesize the sleep debt must have been punishing, or maybe my brain was already paging. Or both.
Anyway it's pretty cool to know I can still learn a ton if I want to. I'm trying hard to make it through the textbooks I have (library or for keeps) before acquiring more. I have a stack of 11 at the couch right now...
