" I don’t know why we long so for permanence, why the fleeting nature of things so disturbs. With futility, we cling to the old wallet long after it has fallen apart. We visit and revisit the old neighborhood where we grew up, searching for the remembered grove of trees and the little fence. We clutch our old photographs. In our churches and synagogues and mosques, we pray to the everlasting and eternal. Yet, in every nook and cranny, nature screams at the top of her lungs that nothing lasts, that it is all passing away. All that we see around us, including our own bodies, is shifting and evaporating and one day will be gone. Where are the one billion people who lived and breathed in the year 1800, only two short centuries ago? "

" For many years, a family of ospreys lived in a large nest near my summer home in Maine. Each season, I carefully observed their rituals and habits. In mid-April, the parents would arrive, having spent the winter in South America, and lay eggs. In early June, the eggs hatched. The babies slowly grew, as the father brought fish back to the nest, and in early to mid August were large enough to make their first flight. My wife and I recorded all of these comings and goings with cameras and in a notebook. We wrote down the number of chicks each year, usually one or two but sometimes three. We noted when the chicks first began flapping their wings, usually a couple of weeks before flying from the nest. We memorized the different chirps the parents made for danger, for hunger, for the arrival of food. After several years of cataloguing such data, we felt that we knew these ospreys. We could predict the sounds the birds would make in different situations, their flight patterns, their behavior when a storm was brewing. Reading our “osprey journals” on a winter’s night, we felt a sense of pride and satisfaction. We had carefully studied and documented a small part of the universe. Then, one August afternoon, the two baby ospreys of that season took flight for the first time as I stood on the circular deck of my house watching the nest. All summer long, they had watched me on that deck as I watched them. To them, it must have looked like I was in my nest just as they were in theirs. On this particular afternoon, their maiden flight, they did a loop of my house and then headed straight at me with tremendous speed. My immediate impulse was to run for cover, since they could have ripped me apart with their powerful talons. But something held me to my ground. When they were within twenty feet of me, they suddenly veered upward and away. But before that dazzling and frightening vertical climb, for about half a second we made eye contact. Words cannot convey what was exchanged between us in that instant. It was a look of connectedness, of mutual respect, of recognition that we shared the same land. After they were gone, I found that I was shaking, and in tears. To this day, I do not understand what happened in that half second. But it was one of the most profound moments of my life. "

" But the psychological change accompanying these technologies is more subtle, and perhaps more important. Consciously and unconsciously, we have gradually grown accustomed to experiencing the world through disembodied machines and instruments. As I stood in line to board an airplane recently, the young woman in front of me was primping in her mirror—straightening her hair, putting on lipstick, patting her checks with blush—a female ritual that has been repeated for several thousand years. In this case, however, her “mirror” was an iPhone in video mode, pointed at herself, and she was reacting to a digitized image of herself. I take walks in a federally protected wildlife preserve near my home in Massachusetts. A dirt trail winds for a mile around a lake teeming with beavers and fish, wild ducks and geese, aquatic frogs. Bulrushes and cattails wrap the perimeter of the pond, water lilies float here and there, rippling when a fish goes by. In the winter, the air is crisp and sharp, in the summer soft and aromatic. And a thick silence lies across the park, broken only by the honking of geese and the croaking of frogs. It is a place to smell, to see, to feel, to quietly let one’s mind wander where it wants. More and more commonly, I see people here talking on their cell phones as they walk around the trail. Their attention is focused not on the scene in front of them, but on a disembodied voice coming from a small box. And they are disembodied themselves. Where are their minds and bodies? Certainly not present in the park. Nor can they be located in the electromagnetic waves and digital signals flowing through cyberspace. Only their voices can be found at the other end of their conversations, in the offices and boardrooms and homes of the people they are talking to. They are attempting to be several places at once, like quantum waves. But I would argue that they are nowhere. "

" Theoretical physicists are Platonists. Until the last few years, they believed that the entire universe, the one universe, was generated from a few principles of symmetry and mathematical truths, perhaps throwing in a handful of parameters like the mass of the electron. It seemed that we were closing in on a vision of our universe in which everything could be calculated, predicted, and understood. However, two theories in physics, called “eternal inflation” and “string theory,” now "

" indicate that the same fundamental principles, from which the laws of nature derive, 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.
