Seite 11 - This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.
Seite 18 - I believe with Schopenhauer that one of the strongest motives that lead men to art and science is escape from everyday life with its painful crudity and hopeless dreariness, from the fetters of one's own ever shifting desires.
Seite 11 - He is not eternity and infinity, but eternal and infinite; he is not duration or space, but he endures and is present. He endures forever, and is everywhere present; and, by existing always and everywhere, he constitutes duration and space.
Seite 11 - I add that it seems rather absurd to ascribe movement to the container or to that which provides the place and not rather to that which is contained and has a place, ie, the Earth. And lastly, since it is clear that the wandering stars are sometimes nearer and sometimes farther away from the...
Seite 53 - We regard the reasons for pursuing this possibility as very compelling, for it is only in such a universe that there is any basis for the assumption that the laws of physics are constant; and without such an assumption our knowledge, derived virtually at one instant of time, must be quite inadequate for an interpretation of the universe and the dependence of its laws on its structure, and hence inadequate for any extrapolation into the future or the past.
Seite 11 - ...if there are globes in the heaven similar to our earth, do we vie with them over who occupies the better portion of the universe? For if their globes are nobler, we are not the noblest of rational creatures. Then how can all things be for man's sake? How can we be the masters of God's handiwork?

Seite 77 - ... gravitational lens" phenomenon. When Einstein published his new theory of gravity, he pointed out that light, like matter, should be affected by gravity. Thus, as light from a distant astronomical object, such as a quasar, travels toward the earth, that light should be deflected by any mass lying between here and there. The intervening mass can act as a lens, distorting and splitting the image of the quasar. Even if the intervening mass is totally invisible, its gravitational effects are not....

Autoren-Profil (1991)

Alan Lightman was born in Memphis, Tennessee on November 28, 1948. After completing an A.B. at Princeton University in 1970, a Ph.D. at the California Institute of Technology in 1974, and postdoctoral studies at Cornell University in 1976, he moved directly into academia, teaching astronomy and physics at Harvard University, the Smithsonian Astrophysical Observatory, and the Massachusetts Institute of Technology. In the 1980s, he found a way to combine his literary and scientific interests when he began to write essays about science. He explored astronomy, cosmology, particle physics, space exploration, and the life of a scientist, writing about these topics in a way that makes them understandable to the average reader. Many of his essays can be found in the collections Time Travel and Papa Joe's Pipe and A Modern-Day Yankee in a Connecticut Court and Other Essays on Science. He is the author of Ancient Light: Our Changing View of the Universe, which won the Boston Globe's 1991 Critics' Choice award for non-fiction; and is co-author of Origins: The Lives and Worlds of Modern Cosmologists, which received an award from the Association of American Publishers in 1990. In the 1990's, he branched out into fiction, although still with a focus on science. His novels include Einstein's Dreams, Good Benito, and The Diagnosis.
