The idle man does not know what it is to enjoy rest.

Science is a wonderful thing if one does not have to earn one's living at it.

The illusion that we are separate from one another is an optical delusion of our consciousness.

I once thought that if I could ask God one question, I would ask how the universe began, because once I knew that, all the rest is simply equations. But as I got older I became less concerned with how the universe began. Rather, I would want to know why he started the universe. For once I knew that answer, then I would know the purpose of my own life.

Yes, we now have to divide up our time like that, between politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever.

Logic can take you from point A to point B. Imagination can take you wherever you want

Anyone who thinks science is trying to make human life easier or more pleasant is utterly mistaken.
