Re: Math

Everywhere you see an x just plug in the number and then do the arithmetic.


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.
