Theo's already on his way. Paul might be too, but communications have been down for so long, I don't know. "Heading out here with a storm like this coming in? That's madness." Dad sighs. "Then again,...

I don't want to be human. I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter. Do you see the absurdity of what I am? I can't even express these things properly, because I...

Justine watched two azure moons traverse the sparkling smear of Wall stars. They were in very strange orbits. And moving impossibly fast – actually accelerating. 'Oh my God,' she gasped. The Raiel's...

I shrugged. I saw a Star Trek episode one time that was along those lines. All the women on this whole planet end up naked. I can't remember exactly, but I think Captain Kirk gets turned into a pipe...

Sometimes I think I must have a Guardian Idiot. A little invisible spirit just behind my shoulder, looking out for me... only he's an imbecile.

"Is the Master out of his mind?' she asked me. I nodded. 'And he's taking you with him?' I nodded again. 'Where?' she asked. I pointed towards the center of the earth. 'Into the cellar?' exclaimed the...

The Three Theorems of Psychohistorical Quantitivity: The population under scrutiny is oblivious to the existence of the science of Psychohistory. The time periods dealt with are in the region of 3...

A voice spoke in his head, mellow and vast: "Who's there?" he quavered. "Who are you?" "Malfunction! Malfunction!" squalled the scouter. "Shut up, it's not a malfunction. Who's talking to me?" The...

Meanwhile, the poor Babel fish, by effectively removing all barriers to communication between different races and cultures, has caused more and bloodier wars than anything else in the history of...

A long fall. Dinah had ceased to even think in terms of up and down. The concept of falling had become meaningless to her.

Tom is a filthy little pustule. If you quote me, I'll deny it!

Perhaps I am a man of exceptional moods. I do not know how far my experience is common. At times I suffer from the strangest sense of detachment from myself and the world about me; I seem to watch it...

Once you realize that power will always end up with the sort of people who crave it, I think that there are worse people who could have it than Peter.

Love isn't just wanting another person the way you want to own an object you see in a store. That's just desire. You want to have it around, take it home and set it up somewhere in the apartment like...

Tomorrow morning, he decided, I'll begin clearing away the sand of fifty thousand centuries for my first vegetable garden. That's the initial step.
