The greatest scientists are artists as well.

The fairest thing we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. It is the source of all true art and science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle.

If you want to know the future, look at the past.

The significant problems we have cannot be solved at the same level of thinking with which we created them.

Every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe-a spirit vastly superior to that of man, and one in the face of which we with our modest powers must feel humble.

The future is an unknown, but a somewhat predictable unknown. To look to the future we must first look back upon the past. That is where the seeds of the future were planted. I never think of the future. It comes soon enough.

A new idea comes suddenly and in a rather intuitive way, but intuition is nothing but the outcome of earlier intellectual experience.
