“I've decided 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.”

“Consider a world in which cause and effect are erratic. Sometimes the first precedes the second, sometimes the second the first.... Each act is an island in time, to be judged on its own. It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning, each touch has no past or future, each kiss becomes a kiss of immediacy.”

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

“Human beings consider themselves satisfied only compared to some other condition. A man who has owned nothing but a bicycle all of his life feels suddenly wealthy the moment he buys an automobile...But this happy sensation wears off. After a while the car becomes just another thing that he owns. Moreover, when his neighbor next door buys two cars, in an instant our man feels wretchedly poor and deprived.”

“In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.”

“Something else gets under your skin, keeps you working days and nights at the sacrifice of your sleeping and eating and attention to your family and friends, something beyond the love of puzzle solving. And that other force is the anticipation of understanding something about the world that no one has ever understood before you.Einstein wrote that when he first realized that gravity was equivalent to acceleration -- an idea that would underlie his new theory of gravity -- it was the "happiest thought of my life." On projects of far smaller weight, I have experienced that pleasure of discovering something new. It is an exquisite sensation, a feeling of power, a rush of the blood, a sense of living forever. To be the first vessel to hold this new thing.All of the scientists I've known have at least one more quality in common: they do what they do because they love it, and because they cannot imagine doing anything else. In a sense, this is the real reason a scientist does science. Because the scientist must. Such a compulsion is both blessing and burden. A blessing because the creative life, in any endeavor, is a gift filled with beauty and not given to everyone, a burden because the call is unrelenting and can drown out the rest of life.This mixed blessing and burden must be why the astrophysicist Chandrasekhar continued working until his mid-80's, why a visitor to Einstein's apartment in Bern found the young physicist rocking his infant with one hand while doing mathematical calculations with the other. This mixed blessing and burden must have been the "sweet hell" that Walt Whitman referred to when he realized at a young age that he was destined to be a poet. "Never more," he wrote, "shall I escape.”
