The quantum theories about, ‘quark’, is as fickle as existence of quark.

I'm fascinated with quantum physics.

[T]he atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts.

A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.

If the business of physics is ever finished, the world will be a much less interesting place in which to live . . .

...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.
