There are things that are so serious that you can only joke about them.

The very act of observing disturbs the system.

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.

My mind was formed by studying philosophy, Plato and that sort of thing.

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

In my paper the fact the XY was not equal to YX was very disagreeable to me. I felt this was the only point of difficulty in the whole scheme...and I was not able to solve it.

The structure underlying the phenomena is not given by material objects like the atoms of Democritus but by the form that determines the material objects. The Ideas are more fundamental than the objects.
