Empirical interest will be in the facts so far as they are relevant to the solution of these problems.

The part an actor played on stage was once written on a separate roll of paper.

The implications of these considerations justify the statement that all empirically verifiable knowledge even the commonsense knowledge of everyday life - involves implicitly, if not explicitly, systematic theory in this sense.

But the fact a person denies that he is theorising is no reason for taking him at his word and failing to investigate what implicit theory is involved in his statements.

I entered the Physics Department in 1950, receiving a Master's degree in 1953 and a Ph.D. in 1956. It is difficult to convey the sense of excitement that pervaded the Department at that time.

I like science fiction. I am quite a technologically kind of up-to-date person. I like seeing what the new developments are.

It turns out that advancing equal opportunity and economic empowerment is both morally right and good economics, because discrimination, poverty and ignorance restrict growth, while investments in education, infrastructure and scientific and technological research increase it, creating more good jobs and new wealth for all of us.

You need virtual reality to understand high level science or high level math. It's very helpful to explain third and fourth dimensional things that people are constantly addressing in quantum physics. But, as soon as you're creating an avatar, and you can live and you can start to feel sensations on VR, that has gone too far.
