It's not necessarily a large number of people that affect the culture. You don't count the number of influential voices, you weigh them. A hundred people can affect the culture.

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.

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?

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.

If the multiverse idea is correct, then the historic mission of physics to explain all the properties of our universe in terms of fundamental principles--to explain why the properties of our universe must necessarily be what they are--is futile, a beautiful philosophical dream that simply isn't true. Our universe is what it is because we are here. The situation could be likened to a school of intelligent fish who one day began wondering why their world is completely filled with water. Many of the fish, the theorists, hope to prove that the entire cosmos necessarily has to be filled with water. For years, they put their minds to the task but can never quite seem to prove their assertion. Then, a wizened group of fish postulates that maybe they are fooling themselves. Maybe there are, they suggest, many other worlds, some of them completely dry, and everything in between.

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

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