“We go to three parks. We walk nonstop or else she cries. The baby likes moving, especially moving at high speeds, so we go on swings. She opens one eye and looks at me with profound suspicion. What is this contraption? she asks silently, a tiny cyclops in my hands. This is a simple harmonic oscillator, I say, a pendulum; this is periodic motion. Wheeeee is the sound I think her temporal lobe wants to make" (p125)”

“.... attempts to combine these two forces with the strong nuclear force into what is called a grand unified theory (GUT). This title is rather an exaggeration: the resultant theories are not all that grand, nor are they fully unified, as they do not include gravity. Nor are they really complete theories, because they contain a number of parameters whose values cannot be predicted from a theory but have to be chosen to fit in with experiment. Nevertheless, they may be a step toward a complete, fully unified theory.”

“Despite this, I have a bet with Kip Thorne of the California Institute of Technology that in fact Cygnus X-1 does not contain a black hole! This is a form of insurance policy for me. I have done a lot of work on black holes, and it would all be wasted if it turned out that black holes do not exist. But in that case, I would have the consolation of winning my bet, which would bring me four years of the magazine Private Eye. If black holes do exist, Kip will get one year of Penthouse. When we made the bet, in 1975, we were 80 per cent certain that Cygnus was a black hole. By now, I would say that we are about 95 per cent certain, but the bet has yet to be settled.”

“The existence of radiation from black holes seems to imply that gravitational collapse is not as final and irreversible as we once thought. If an astronaut falls into a black hole, its mass will increase, but eventually the energy equivalent of that extra mass will be returned to the universe in the form of radiation. Thus, in a sense, the astronaut will be 'recycled'. It would be a poor sort of immortality, however, because any personal concept of time for the astronaut would almost certainly come to an end as he was torn apart inside the black hole! Even the types of particles that were eventually emitted by the black hole would in general be different from those that made up the astronaut: the only feature of the astronaut that would survive would be his mass or energy.”
