Please interpret the following statements for me in terms of the behavior of the physical world, and tell me which branch of physics deals with the behavior of each:

Behavior of: concept-representations constructed of activation patterns in neural nets

I think you can figure out the branches of science (and their relationships to the underlying physics) yourself.

Again: do you think you're doing mathematics with a magical soul? No! You have thinkmeat! And if you're not using that, you're using some other computational device - probably electronic - to push the concepts around.
