“He pointed to another number, changing as rapidly as the first, but on a lower trajectory; it rose to a high of 8.79 rem per hour. Several lifetimes of dentists’ X-rays, to be sure; but the radiation outside the storm shelter would have been a lethal dose, so they were getting off lightly. Still, the amount flying through the rest of the ship! Billions of particles were penetrating the ship and colliding with the atoms of water and metal they were huddled behind; hundreds of millions were flying between these atoms and then through the atoms of their bodies, touching nothing, as if they were no more than ghosts. Still, thousands were striking atoms of flesh and bone. Most of those collisions were harmless; but in all those thousands, there were in all probability one or two (or three?) in which a chromosome strand was taking a hit, and kinking in the wrong way: and there it was. Tumor initiation, begun with just that typo in the book of the self. And years later, unless the victim's DNA luckily repaired itself, the tumor promotion that was a more or less unavoidable part of living would have its effect, and there would appear a bloom of Something Else inside: cancer. Leukemia, most likely; and, most likely, death.”

“It seemed to him that nothing would ever be explained, and that all of a sudden each day was slipping away, that time was flying by and they were getting old and nothing would ever come clear.”

“They were so ignorant! Young men and women, educated very carefully to be apolitical, to be technicians who thought they disliked politics, making them putty in the hands of their rulers, just like always. It was appalling how stupid they were, really, and he could not help lashing into them.”

“Atoms, in short, are very abundant. They are also fantastically durable. Because they are so long lived, atoms really get around. Every atom you possess has almost certainly passed through several stars and been part of millions of organisms on its way to becoming you. We are each so atomically numerous and so vigorously recycled at death that a significant number of our atoms-- up to a billion for each of us, it has been suggested-- probably once belonged to Shakespeare.”

“All the repetitions in the pattern were superficial; the moment was always new. It had to be lived, and then the next moment embraced as it arrived.”

“We were outside the world, we didn't even own things -- some clothes. . . . This arrangement resembles the prehistoric way to live, and it therefore feels right to us, because our brains recognize it from 3 millions of years practicing it. In essence our brains grew to their current configuration in response to the realities of that life. So as a result people grow powerfully attached to that kind of life, when they get the chance to live it. It allows you to concentrate your attention on the real work, which means everything that is done to stay alive, to make things, or satisfy one's curiosity, or play. That is utopia.”

“If we were to name the most powerful assumption of all, which leads one on and on in an attempt to understand life, it is that all things are made of atoms, and that everything that living things do can be understood in terms of the jigglings and wigglings of atoms.”
