Only zombies like raw brain.Cooked brain, preferably well done with some lemon or garlic sauce smeared on it is my cup of tea. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
