Mr G: A Novel About the Creation
Our comfort with nature is an illusion. Here on earth, even with our earthquakes and storms, we have no conception of the range and the power of nature. In many other parts of the cosmos, conditions are far more extreme than on earth and quite inhospitable to life. On the planet Mercury, for example, the temperature reaches 800 degrees. On Neptune, it is minus 370. On Uranus, the winds exceed 350 miles per hour. With the recent work of the Kepler spacecraft, searching for planets favorable for life, we can estimate that only about one millionth of one billionth of 1 percent of the material of the visible universe exists in living form. From a cosmic perspective, we and all life are the exception to the rule.

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.

Order is the law of nature, the universal trend, the cosmic direction. If time is an arrow, that arrow points toward order. The future is pattern, organization, union, intensification; the past, randomness, confusion, disintegration, dissipation.

Einstein's Dreams
One cannot walk down an avenue, converse with a friend, enter a building, browse beneath the sandstone arches of an old arcade without meeting an instrument of time. Time is visible in all places. Clock towers, wristwatches, church bells divide years into months, months into days, days into hours, hours into seconds, each increment of time marching after the other in perfect succession. And beyond any particular clock, a vast scaffold of time, stretching across the universe, lays down the law of time equally for all.

What sense is there in continuing when one has seen the future?

If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.

As human beings, don't we need questions without answers as well as questions with answers, questions that we might someday answer and questions that we can never answer?
