But what is the past? Could it be, the firmness of the past is just illusion? Could the past be a kaleidoscope, a pattern of images that shift with each disturbance of a sudden breeze, a laugh, a thought? And if the shift is everywhere, how would we know?
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?
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.
The relationship between science and the humanities is two-way. Science changes our view of the world and our place in it. In the other direction, the humanities provide the store of ideas and images and language available to us in understanding the world. The exploding star of A.D. 1054, the Crab Nebula, was sighted and documented by the Chinese, but nowhere mentioned in the West, where the Aristotelian notion of the immortality of stars still held sway. We often do not see what we do not expect to see.
One metaphor for how we are living is that you see so may people with cell phones. In restaurants, walking, they have cell phones clamped to their to heads. When they are on their cell phones they are not where their bodies are...they are somewhere else in hyperspace. They are not grounded. We have become disembodied. By being always somewhere else we are nowhere.
I'm still happy with the way Einstein's Dreams came out. That book came out of a single inspiration. I really felt like I was not creating the words, that I was hearing the words. That someone else was speaking the words to me and I was just writing them down. It was a very strange experience. That can happen with a short book. I don't think it could happen with a long book.
Nature is purposeless. Nature simply is. We may find nature beautiful or terrible, but those feelings are human constructions. Such utter and complete mindlessness is hard for us to accept. We feel such a strong connection to nature. But the relationship between nature and us is one-sided. There is no reciprocity. There is no mind on the other side of the wall.
We live in a highly polarized society. We need to try to understand each other in respectful ways. To that end, I believe that we should make room for both spiritual atheists and thinking believers.
The history of science can be viewed as the recasting of phenomena that were once thought to be accidents as phenomena that can be understood in terms of fundamental causes and principles.
You say, "Something important really happened here. I really had hold of something I was visited by the muse." And that's enough to make you continue the months and years to finish the whole book.
I consider myself an essayist and a fiction writer. In the essays, I certainly have been influenced by some of the leading science essayists. Like Loren Eiseley, Stephen Jay Gould, Lewis Thomas.
If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.
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.
