The ultimate aim of all science is to penetrate the unknown.

This I know the spirit of Man cannot be stopped.

There's no term to the work of a scientist.

Tired minds don't plan well. Sleep first, plan later.

Why does man freeze to death trying to reach the North Pole? Why does man drive himself to suffer the steam and heat of the Amazon? Why does he stagger his mind with the mathematics of the sky? Once the question mark has arisen in the human brain the answer must be found, if it takes a hundred years. A thousand years.

I don't sleep. I hate those little slices of death.

A scientist who cannot prove what he has accomplished, has accomplished nothing.

Don't you see what's at stake here? The ultimate aim of all science to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.
