P.S. Sorry if I came off sounding like your Dad, but I was concerned. I lecture often at the university level on national security, as well as bio sensors, but whats really fun is discussing with university students the history of technology and it's impact on society. Like being in the eye of a hurricane, all may seem very calm , but it never stays that way for long. The only thing I demand of my students is they think, always question so-called authority. I have had serious issues with far left and far right wing "professors" who make it clear as loud as possible that not to reflect their views means someones an idiot, fascist, or you name it. Those who would use ridicule like this in a classroom setting only highlight an insecure, and small mind. I can't recall the author but the book: The Tao of Physics" presents or starts to present complex physics in a semi-digestible manner. I also require my students to argue what ever position they are at on a subject. You may be totally wrong in a conclusion, but I look at the train of logic, not as much where the tracks take you.

And last you will get discouraged and annoyed at the b.s. from time to time. Don't let it bug 'ya, its all part of the game. Good Luck, Bob.
