An expert is someone who knows some of the worst mistakes that can be made in his subject and how to avoid them.

I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.

By getting to smaller and smaller units, we do not come to fundamental or indivisible units. But we do come to a point where further division has no meaning.

I think that modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language.

The one who insists on never uttering an error must remain silent.

What we observe is not nature itself, but nature exposed to our method of questioning.

The Same organizing forces that have shaped nature in all her forms are also responsible for the structure of our minds.
