I got tired of the mathematical masturbation that I saw in advanced Physics. I was much more interested in what was actually happening in the physical universe.
Yes, Dirac’s mathematical models predicted anti-particles, but that IMO was just luck. There are lots of solutions to equations which are not physical.
I want to know what mechanism determines the probability of a photon reflecting from a partially reflective surface. Not the equation that describes it, but rather the mechanism which causes it.
I want to know what the hell is going on, and the more I learned about quantum mechanics, the more I got the impression that our brains are not capable of understanding the building blocks of the universe.
I’m not saying that the universe is incomprehensible. I’m saying that human brains have a subset of the capabilities required to understand the universe because brains evolved to propagate life forms, not to comprehend the universe.
I think that it is entirely possible that we could build a machine which would understand the universe, but I don’t think it could share its comprehension with us.
