Inflation takes advantage of this possibility... to let gravity be the repulsive force that drove the universe into the period of expansion that we call the Big Bang. In fact, when one combines general relativity with conventional ideas, now, in particle physics there really is a pretty clear indication, I should say, not quite a prediction... that at very high energy densities one expects to find states of matter which literally turn gravity on its head and cause gravity to become repulsive.

[Regarding Flashdance-related fame] It was very clear to me that it's not real. It's not real...I was never the little girl who thought I wanted to be famous. My first real quest that I can recall...other than wanting to be a jockey...was trying to figure out who or what God was. That really drove me for quite some time...I had a notion that there was this mystery that I didn't really know anything about, and I wanted to try to figure it out.... so fame was not my driving force.

I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.

Yes, [I spent] two long years, traveling all over the United States, all over Europe, interviewing many, many, many people who had been thrown out of their academic jobs because they taught that there was a possibility of life coming from something other than Darwinism, who thought that possibly random selection and mutations didn't account for the universe, didn't account for gravity, didn't account for why nobody had ever seen an individual species evolve -- no one's ever seen an individual species evolve!"

I have to say, I think that we are in some kind of final examination as to whether human beings now, with this capability to acquire information and to communicate, whether we're really qualified to take on the responsibility we're designed to be entrusted with. And this is not a matter of an examination of the types of governments, nothing to do with politics, nothing to do with economic systems. It has to do with the individual. Does the individual have the courage to really go along with the truth?

What we really need the poet's and orator's I help to keep alive in us is not, then, the common and gregarious courage which Robert Shaw showed when he marched with you, men of the Seventh Regiment. It is that more lonely courage which he showed when he dropped his warm commission in the glorious Second to head your dubious fortunes, negroes of the Fifty-fourth. That lonely kind of courage (civic courage as we call it in times of peace) is the kind of valor to which the monuments of nations should most of all be reared.
William James
