“And the most interesting natural structure?A giant, two-thousand-mile-long fish in orbit around Jupiter, according to a reliable report in the Weekly World News. The photograph was very convincing, and I'm only surprised that more-reputable journals like New Scientist, or even just The Sun, haven't followed up with more details. We should be told.”

“I myself have dreamed up a structure intermediate between Dyson spheres and planets. Build a ring 93 million miles in radius - one Earth orbit - around the sun. If we have the mass of Jupiter to work with, and if we make it a thousand miles wide, we get a thickness of about a thousand feet for the base.And it has advantages. The Ringworld will be much sturdier than a Dyson sphere. We can spin it on its axis for gravity. A rotation speed of 770 m/s will give us a gravity of one Earth normal. We wouldn't even need to roof it over. Place walls one thousand miles high at each edge, facing the sun. Very little air will leak over the edges.Lord knows the thing is roomy enough. With three million times the surface area of the Earth, it will be some time before anyone complains of the crowding.”

“A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At teh end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever, " said the old lady. "But it turtles all the way down!”

“The future, according to some scientists, will be exactly like the past, only far more expensive.”

“This isn't a weapon cache-search mission during which we kick down doors looking for suspects. We pour concrete lands where IED exploded to keep insurgents from planting more. No news reporters followed us around, because soldiers saving lives aren't as interesting as soldiers taking lives.”

“I leaned my head back and closed my eyes. "We're supposed to be celebrating our two-week anniversary tonight.""Uh, news for you, honey - two weeks is no anniversary.""What should I tell him? I don't even want to go.""Tell him you just got a new bra and it's shy around strangers.”
