The most superior of scientific goals is to embrace a maximum of experiment with a minimum of hypotheses.

My scientific work is motivated by an irresistible longing to understand the secrets of nature not by other feelings.

It is my fate to be considered an authority, since I spent my youth rebelling against it.

Look deep into nature, and then you will understand everything better.

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.

I refuse to make money out of my science. My laurel is not for sale like so many bales of cotton.

Success comes from curiosity, concentration, perseverance and self criticism.
