No secrecy involved here. I'd have written exactly what he said, if I had any hope of remembering it, and the meaning would have been the same: nothing. Smith never seemed to mind if his audience was coming into the clubhouse two or three holes behind him; he rattled off his own private jargon without regard to whether or not it was being monitored. Sometimes I thought it just helped him to think out loud. Sometimes I thought he was showing off. Probably a little of both.
But I can't get away from the subject of the interstellar drive without mentioning the one time he made an attempt to put it in layman's terms. It stuck in my mind, possibly because Smith had a way of making "layman" rhyme with "retarded."
"There are basically three states of matter," he had said. "I call them wackiness, dogmatism, and perversity. The universe of our experience is almost totally composed of dogmatic matter, just as it's mostly what we call 'matter,' as opposed to 'anti-matter'-though dogmatic matter includes both types. Every once in a great while we get evidence of some perverse matter. It's when you move into the realm of the wacky that you have to watch out."
"I've known that all my life," I had told him.
"Ah, but the possibilities!" he had said, waving his hand at the drive taking shape in the engine room of the Heinlein.
As he did now, providing the sort of segue I hate when a director does it in a movie, but the fact is Smith had a habit of waving his hand grandly when coming upon his mighty works. Hell, he had a right.
"See what can come from the backwaters of science?" he said. "Physics is a closed book, they all said. Put your talents to work in something useful."
"'They jeered me at the Sorbonne!'" I suggested.
"They threw eggs when I presented my paper at the Institute! Eggs!" He leered at me, dry-washing his hands, hunching his shoulders. "The fools! Let them see who has the last laugh, ha ha HA!" He dropped the mad scientist impression and patted a huge machine on its metal flank, a cowboy gentling a horse. Smith could have been insufferably stuffy except for the fact he'd seen almost as many old movies as I had.
"No kidding, Hildy, the fools are going to be impressed when they see what I've wrung out of the tired old husk of physics."
"You'll get no argument from me," I said. "What happened to physics, anyway? Why was it neglected for so long?"
"Diminishing returns. They spent an insane amount of money on the GSA about a century ago, and when they turned it on they found out they'd hubbled it up. The repairs would have-"
"The GSA?"
"Global Supercooled Accelerator. You can still find a lot of it, running right around the Lunar equator."
I remembered it then; I'd followed it part of the way when I ran in the Equatorial Rover Race.
"They built big instruments out in space, too. They learned a lot about the universe, cosmologically and sub-atomically, but very little of it had any practical use. It got to where learning any more, in the directions physics kept going, would cost trillions just to tool up. If you did it, when you were done you'd have learned what went on in the first billionth of a nano-second of creation, and then you'd just naturally want to know what happened in the first thousandth of a nano-nano-second, only that'd cost ten times as much. People got tired of paying those kind of bills to answer questions even less reality-based than theology, and the smart people noticed that for peanuts you could find out practical things in biological science."
"So all the original research now is in biology," I said.
"Hah!" he shouted. "There is no original research, unless you count some of the things the Central Computer does. Oh, a few people here and there." He waved his hand, dismissing them. "It's all engineering now. Take well-known principles and find a way to make a better toothpaste." His eyes lit up. "That's a perfect example. A few months back, I woke up and my mouth tasted like peppermint. I looked into it, turns out it's a new sort of 'bot. Some idiot thought this up, built it, and let it loose on an unsuspecting public. It's in the water, Hildy! Can you imagine?"
"It's a crying shame," I muttered, trying not to meet his eye.
"Well, I got the antidote. Maybe my mouth does taste rotten in the morning, but at least it tastes like me. Reminds me who I am." Which I guess is a perfect example of both the perversity of Heinleiners and the cultural passivity they rebelled against. And the big reason I liked them, in spite of their best efforts to thwart my affection.
"It's all handed down from on high now," he went on. "We're like savages at an altar, waiting for miracles to be handed down. We don't envision the miracles we might work, if we set ourselves to it."
"Like little people, eight inches high and smart as lab rats."
He winced, the first indication I'd had of a moral uncertainty. Thank god for that; I like people to have opinions, but people with no doubts scare me.
"You want me to defend that? Okay. I've brought those children up to think for themselves, and to question authority. It's not unlimited; me or somebody who knows more about it has to approve their projects, and we keep an eye on them. We've created a place where they can be free to make their own rules, but they're children, they have to follow our rules, and we set as few as possible. Do you realize this is the only place in Luna where the eyes of our mechanical Big Brother can't look? Not even the police can come in here."
"I have no reason to love the Central Computer, either."
"I didn't think so. I thought you might have a story to tell about that, or I'd never have let you in. You'll tell it when you're ready. Do you know why Libby makes little people?"
"I didn't ask him."
"He might have told you; might not have. It's his solution to the same problem I'm working on: interstellar travel. His reasoning is, a smaller human being requires less oxygen, less food, a smaller spacecraft. If we were all eight inches high, we could go to Alpha Centauri in a fuel drum."
"That's crazy."
"Not crazy. Ridiculous, probably. Unattainable, almost certainly. Those kewpies live about three years, and I doubt they'll ever have much of a brain. But it's an innovative solution to a problem the rest of Luna isn't even working on. Why do you think Gretel goes running across the surface in her birthday suit?"
"You weren't supposed to know about that."
"I've forbidden it. It's dangerous, Hildy, but I know Gretel, and I know she's still trying it. And the reason is, she hopes she'll eventually adapt herself to living in vacuum without any artificial aids."
I thought of the fish stranded on the beach, flopping around, probably doomed but still flopping.
"That's not how evolution works," I said.
"You know it and I know it. Tell it to Gretel. She's a child, and a smart one, but with childish stubbornness. She'll give it up sooner or later. But I can guarantee she'll try something else."
"I hope it's less hare-brained."
"From your lips to God's ears. Sometimes she…" He rubbed his face, and made a dismissing gesture with his hand. "The kewpies make me uneasy, I'll admit that. You can't help wondering how human they are, and if they are human, whether or not they have any rights, or should have any rights."
"It's experimentation on humans, Michael," I said. "We have some pretty strong laws on that subject."
"What we have are taboos. We do plenty of experimentation on human genes. What we're forbidden to do is create new humans."
"You don't think that's a good idea?"
"It's never that simple. What I object to are blanket bans on anything. I've done a lot of research into this-I was against it at first, just like you seem to be. You want to hear it?"
