Twelfth lecture aqvanced quantum mechanics
was a detour to relativistic world, a world which is not completely detached from ours. Yet it has special (relativity) rules, it has a special look and feel: in full accordance with pre-Chirstmas feelings we all have. We talk about Minkowski and his sudden death, we’ve derived plenties of physical laws from Lorentz invariance, got quantum-mechanical and reached Dirac equation. We have second-quantized it and filled Dirac cellar with electrons. That’s it, we would be able to proceed with quantum electrodymanics if it was an intention of the course.
The relativistic mechanics is the most ancient part of the course. At some stage I wanted to scrap it for the sake of more practical things but I was stopped by more practical colleagues who remembered a pre-Christmas feeling of the topic. So I use to gave it.
That has been the last lecture, and I have to say good-bye to the course. I will not read it at least for a number of years. Will miss it. Thanks to all students attending!
Anyway the semester is over, I could enjoy this if I did not have to finish some papers before Christmas… No time to relax yet.

At the end of this great course, I just want to let everbody know that I am a big fan of this weblog. It is a lot of fun to read the reviews on the lectures! Today I made the exam. The first question was a bit different from the questions I saw on earlier exams but I think I made it half way :P.
