Some light quantum mechanics (with minutephysics)

[youtube https://www.youtube.com/watch?v=MzRCDLre1b4] The math of superposition and quantum states. minutephysics channel: https://www.youtube.com/user/minuteph… Brought to you by you: http://3b1b.co/light-quantum-thanks And by Brilliant: https://brilliant.org/3b1b Huge thanks to my friend Evan Miyazono, both for encouraging me to do this project, and for helping me understand many things along the way. This is a simple primer for how the math of quantum mechanics, specifically in the context of polarized light, relates to the math of classical waves, specifically classical electromagnetic waves. I will say, if you *do* want to…

Negative Probabilities

I found this great article from 2013 posts of Azimuth blog. I didn’t understand it completely but I should say that is amazing! I really enjoy it. I must read some other times. Negative Probabilities The physicists Dirac and Feynman, both bold when it came to new mathematical ideas, both said we should think about negative probabilities. These days, Kolmogorov’s axioms for probabilities are used to justify formulating probability theory in terms of measure theory. Mathematically, the theory of measures that take negative or even complex values is well-developed. So, to…
