Ive read two different general physics books in Hallidays and Randall Knights, finished with A’s in all 3 general physics classes, and recently taken a classical mechanics course where i just barely passed. Most of my issue comes from reading textbooks like ours was Taylors book and most the time, if it wasnt something i saw in general physics, i was absolutely confused and the majority of my learning came from lectures and the very few office hours i can rarely make due to work. Also reading griffiths e&m book, for the past 2 weeks have been stuck on chapter 2. I feel like the book isnt for me and lacks what i need to learn such as explanations at almost every step being the biggest one (not necessarily showing all math steps but at least a conceptual explanation as why certain things are being done) . Are there really any books like that in upper division physics or am i just stuck

I have taken an electronics class and kept the lab manual and the free circuit kit and built basic circuits like AND gates and RC oscillators and others from it, I was curious of any books or websites that goes through the use of certain circuits (as my school doesnt really do that) as well as a bunch of circuit diagrams that i could build

I practically dont use FB, neither does my sister. I opened it up today and for some reason i can access her account. We never talked about FB, she doesnt know my emails or anything. My FB account was essentially a throwaway account i made when i was younger for a video game groupchat so it doesnt same my name but somehow it says i “manage her page” in the accounts center which im sure is a new account. Idk if she has access to mime or not. How do i remove or unlink our accounts?
