“You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.”

“A photograph never grows old. You and I change, people change all through the months and years but a photograph always remains the same. How nice to look at a photograph of mother or father taken many years ago. You see them as you remember them. But as people live on, they change completely. That is why I think a photograph can be kind.”

“the only escape from the miseries of life are music and cats...”

“You do not really understand something unless you can explain it to your grandmother.”

“What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism.”

“I am not more gifted than the average human being. If you know anything about history, you would know that is so--what hard times I had in studying and the fact that I do not have a memory like some other people do… I am just more curious than the average person and I will not give up on a problem until I have found the proper solution. This is one of my greatest satisfactions in life--solving problems--and the harder they are, the more satisfaction do I get out of them. Maybe you could consider me a bit more patient in continuing with my problem than is the average human being. Now, if you understand what I have just told you, you see that it is not a matter of being more gifted but a matter of being more curious and maybe more patient until you solve a problem.”
