Relativity teaches us the connection between the different descriptions of one and the same reality.

I want to know how God created this world. I am not interested in this or that phenomenon, in the spectrum of this or that element. I want to know God's thoughts, the rest are details.

A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.

If I had only known, I would have been a locksmith.

I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought about as a child. Bu t my intellectual development was retarded,as a result of which I began to wonder about space and time only when I had already grown up.

On the other hand, although I have a regular work schedule, I take time to go for long walks on the beach so that I can listen to what is going on inside my head. If my work isn't going well, I lie down in the middle of a workday and gaze at the ceiling while I listen and visualize what goes on in my imagination.

Mathematics are well and good but Nature keeps dragging us around by the nose.
