American physicist & author (1948- )
As I understand it, a universe is a ... well, a totality. A universe is everything that is, as far as the inside of the thing.

Mr G: A Novel About the Creation
When a traveler from the future must talk, he does not talk but whimpers. He whispers tortured sounds. He is agonized. For if he makes the slightest alteration in anything, he may destroy the future. At the same time, he is forced to witness events without being part of them, without changing them. He envies the people who live in their own time, who can act at will, oblivious of the future, ignorant of the effects of their actions. But he cannot act. He is an inert gas, a ghost, a sheet without soul. He has lost his personhood. He is an exile of time.

Einstein's Dreams
My writings are an exploration, and I think a lot of writers would tell you this, but in writing, you're not simply putting down things that are already known to you. You're actually discovering in the writing process, you're actually creating knowledge.

So many little lives, amounting to nothing. I ask you: What is infinity multiplied by zero? It is hardly worth our discussion.

Mr G: A Novel About the Creation
I think that the scienti?c way of looking at the world, and the humanistic way of looking at the world are complementary. There are important differences which should be preserved, and in trying to do away with those differences we would lose something the same way as if we tried to make all religions one religion or all races one race. There is a cultural diversity that's very valuable, and it's valuable to have different ways of looking at the world.

Despite our strongly felt kinship and oneness with nature, all the evidence suggests that nature doesn't care one whit about us. Tornadoes, hurricanes, floods, earthquakes and volcanic eruptions happen without the slightest consideration for human inhabitants.

Oh, love is very much a physical thing.... I realize that it's very complicated, and I'm sure it can't be traced to individual neurons and hormones, but I think it's very much a physiological sensation that takes place in the brain.

Ghost
No one knows the nature of God, or even if God exists. In a sense, all of our religions are literary works of the imagination.

If you over-plot your book you strangle your characters. Your characters have to have enough freedom and life to be able to surprise you.

interview, Identity Theory, November 16, 2000
Don't you feel something magical when you're in love?... I do, I certainly do ... but I think that feeling of magic is a hardwired psychological response. It's a chemical thing in the brain. It's a flow of chemicals and electrical currents, and it developed over millions of years in the process of evolution to aid in the procreation of the species.

Einstein's Dreams
To name a thing, one needs to have gathered it, distilled and purified it, attempted to identify it with clarity and precision. One puts a box around the thing and says what's in the box is the thing and what's not is not.

"Words", A Sense of the Mysterious: Science and the Human Spirit
That has been the great achievement of our age: to so thoroughly flood the planet with megabits that every image and fact has become a digitized disembodied nothingness. With magnificent determination, our species has advanced from Stone Age to Industrial Revolution to Digital Emptiness. We've become weightless, in the bad sense of the word.

Reunion
In a world in which time is a circle, every handshake, every kiss, every birth, every word, will be repeated precisely.

Einstein's Dreams
I do not think we will ever have a complete theory of nature. The history of science has been a continuing progress of deeper and deeper understanding, of theories with greater and greater accuracy and predictive power. I see no reason why this progression will come to an end. But even if it did come to an end, in the sense that we had one master equation that contained all the fundamental principles of nature, there would still be a great deal for science to do. The working out of that equation and application of it to all the zillions of different physical situations of matter and energy on earth would occupy scientists for eons. That ultimate master equation would be like knowing the rules of chess. Once you know how the bishop moves and the pawn moves and the queen moves, you have not conquered the game. There are still zillions of different possible configurations on the chessboard, and lots of different strategies that need to be analyzed and explored -- requiring renewed creativity. So, I see scientists in business for a long time, at least for the next 5 billion years until our sun burns out.

Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness is no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock.

Einstein's Dreams
Two theories in physics, eternal inflation and string theory, now suggest that the same fundamental principles from which the laws of nature derive may lead to many different self-consistent universes, with many different properties. It is as if you walked into a shoe store, had your feet measured, and found that a size 5 would fit you, a size 8 would also fit, and a size 12 would fit equally well. Such wishy-washy results make theoretical physicists extremely unhappy. Evidently, the fundamental laws of nature do not pin down a single and unique universe. According to the current thinking of many physicists, we are living in one of a vast number of universes. We are living in an accidental universe. We are living in a universe uncalculable by science.

"The Accidental Universe: Science's Crisis of Faith", Harper's Magazine, December 2011
When the first mechanical clocks were invented, marking off time in crisp, regular intervals, it must have surprised people to discover that time flowed outside their own mental and physiological processes. Body time flows at its own variable rate, oblivious to the most precise hydrogen master clocks in the laboratory. In fact, the human body contains its own exquisite time-pieces, all with their separate rhythms. There are the alpha waves in the brain; another clock is the heart. And all the while tick the mysterious, ruthless clocks that regulate aging.
