  I have interesting story from my highschool. I had a good teacher of physics but he was quite burnt out. He had a lot of knowledge but wasn't motivated to get new when I asked him tricky questions. When I was in graduating year me and my classmates chose subjects we wanted to be tested from. However I was the only one that voted for physics and school couldn't afford to give me classes I needed. So I started to study by myself. It was pretty hard because when there were some easy concepts that I couldn't understand, I didn't have anyone to explain them. On the other hand it was big advantage because I could come up with something by myself and I learned how to think, be independent and with that it was easier to remember the topics

  Thank you so much for your videos! Some questions to this one: 1. If you say A^\mu = (..,...) you're actually saying that a component equals a vector. Is this just sloppy physicist style or is A^\mu really the name of the whole vector? 2. Why do you write the indices of the E up? 3. Taking down the indices of the partial derivatives (while regarding the sign), does it just "work" or is it mathematically correct? Because applying a dual object to a "normal" object isn't the same as applying a "normal" object to another "normal" object. ("normal" = not dual)

  The way you started the video I thought it was gonna be like drink water, don't procrastinate kind of videos but this was actually tremendously useful. How can you say that everyone knows that already in the into? At least for me I have a terrible sense of timing. Most of the time I can't judge how many days I should study and by what quantity. I always forget to write down things and do the simple math just like you did which would apparently save me a lot down the road.

  I can think of so many times in life when I screwed up in school and many times it began by over committing myself and not making sure I had time to make sure I'm enjoying my life. I'm not saying we should blow off our work all the time to go out with friends but we do have to be mindful about making sure we are meeting our physical, emotional, and psychological needs. Those don't go away. They're as important as food and water. Remember, nature always wins so we must respect it.

  As a theoretical physicist, I am feeling personally attacked by the “boundary terms are always zero” line. Because boundary terms in the Lagrangian density is our kryptonite.

  This video is really special. It captures what I love and miss about research - a feeling I never quite got to experience at this depth from the undergraduate level. This feeling is exactly why after years of being in the workforce I’m returning to grad school this fall. Thank you for your genuine experience that you share through your vlog.

  Thanks for the awesome explanation! I have a question about the way you multiplied M^-1 and f(x). We should get two components, not ( )+( ). No?

  There is a more straightforward proof by rewriting the quantum state in terms of position(or momentum) coordinates by inner products formula. And then rewrite the quantum state in the inner product as momentum(or position) specification, and finally compare to the Fourier transform formula to get the result. The proof is much simpler.

  Could a single geometrical process square ψ², t², e², c², v² forming our maths? We need to go back to r² and the three dimensional physics of the Inverse Square Law. Even back to the spherical 4πr² geometry of Huygens’ Principle of 1670. The Universe could be based on simple geometry that forms the potential for evermore complexity. Forming not just physical complexity, but also the potential for evermore-abstract mathematics.

  @Andrew Dotson, This is a great idea for breakups. LOL. It delivers the bad news in a professional manner without the emotional pain. I should copy and paste one of these letters somewhere and use it as a real break up letter: "Dear (ex's name here), I regret to inform you that your admission to the wife program has not been accepted. With 200 possible candidates but only one permanent wife slot available and 3 "backup plan" slots available, our evaluation of each candidate is, naturally, highly competitive. I wish you well in your further endeavors as I am sure you will find other programs which better meet your needs. Sincerely, - me."
