Thank you!! Vexlio has no learning curve - it's literally so easy to use that I haven't had to read ANYTHING in order to get accustomed to doing what I need to do. I simply open the program and the UI is so intuitive that literally you will simply have no issues figuring out what you need to do to accomplish what you want to accomplish. When it comes to books: what are you interested in? Math / physics books or more general stuff? My favorite book of all time is 'Crime and Punishment' - it literally shows you how Dostoevsky thinks and puts you inside of his mind - not many books can do this.

I will give Vexlio a try! I don't have a book category per se, but I read freakonomics last year, and was very impressed by it, if you have similar recommendation, would appreciate it! I read Crime and Punishment but long time ago in high school, don't remember much of it though.

Sure - like I said, it's hard for me to say what my favorite is without naming a category, but since we're on the topic of Electromagnetism I'll stick to physics and recommend 1) Introduction to Elementary Particles by Griffiths (best into to standard model in particle physics) and 2) QED by Richard Feynman. QED btw is very well done and literally shows you the 'algorithm' behind standard particle physics and does so in a clear and unambiguous manner - really an amazing work by Feynman.
