In my relativity theory I set up a clock at every point in space, but in reality I find it difficult to provide even one clock in my room.

So I am living without fats, without meat, without fish, but am feeling quite well this way. It always seems to me that man was not born to be a carnivore.

There's something to be said for relatives...it has to be said because it's unprintable!

When the Special Theory of Relativity began to germinate in me, I was visited by all sorts of nervous conflicts... I used to go away for weeks in a state of confusion.

I know little about nature and hardly anything about men.

A finely tempered nature longs to escape from the personal life into the world of objective perception and thought.

There are two ways to live: you can live as if nothing is a miracle; you can live as if everything is a miracle.
