Sometimes it's very hard to turn off my brain especially when I have an eighteen hour day. I try to stop working by 10 or 11pm but you know sometimes there is nothing I can do about it.

We admit, in geometry, not only infinite magnitudes, that is to say, magnitudes greater than any assignable magnitude, but infinite magnitudes infinitely greater, the one than the other. This astonishes our dimension of brains, which is only about six inches long, five broad, and six in depth, in the largest heads.
