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.

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
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.

The target of power is more interesting than its quantity.

Einstein's Dreams
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.

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?

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