Foundation's Edge by Isaac Asimov

you to the spaceport,” she said, “but there are those who will, and you must make no effort to do anything you are not told to do. I believe they will kill you if you make an effort to escape. The fact that I will not be with them will remove any inhibition.”
    Trevize said, “I will make no unauthorized effort, Madam Mayor, but one thing-“
    “Yes?”
    Trevize searched his mind rapidly and finally said with a smile that he very much hoped looked unforced, “The time may come, Madam Mayor, when you will ask me for an effort. I will then do as I choose, but I will remember the past two days.”
    Mayor Branno sighed. “Spare me the melodrama. If the time comes, it will come, but for now-I am asking for nothing.”
     

Foundation 4 - Foundation's Edge

CHAPTER FOUR
    SPACE
     
    THE SHIP LOOKED EVEN MORE IMPRESSIVE THAN TREVIZE - WITH HIS memories of the time when the new cruiser-class had been glowingly publicized-had expected.
    It was not the size that was impressive-for it was rather small. It was designed for maneuverability and speed, for totally gravitic engines, and most of all for advanced computerization. It didn’t need size-size would have defeated its purpose.
    It was a one-man device that could replace, with advantage, the older ships that required a crew of a dozen or more. With a second or even a third person to establish shifts of duty, one such ship could fight off a flotilla of much larger non-Foundation ships. In addition, it could outspeed and escape from any other ship in existence.
    There was a sleekness about it-not a wasted line, not a superfluous curve inside or out. Every cubic meter of volume was used to its maximum, so as to leave a paradoxical aura of spaciousness within. Nothing the Mayor might have said about the importance of his mission could have impressed Trevize more than the ship with which he was asked to perform it.
    Branno the Bronze, he thought with chagrin, had maneuvered him into a dangerous mission of the greatest significance. He might not have accepted with such determination had she not so arranged matters that he wanted to show her what he could do.
    As for Pelorat, he was transported with wonder. “Would you believe,” he said, placing a gentle finger on the hull before he had climbed inside, “that I’ve never been close to a spaceship?”
    “I’ll believe it, of course, if you say so, Professor, but how did you manage it?”
    “I scarcely know, to be honest with you, dear fel-, I mean, my dear Trevize. I presume I was overly concerned with my research. When one’s home has a really excellent computer capable of reaching other computers anywhere in the Galaxy, one scarcely needs to budge, you know. -Somehow I expected spaceships to be larger than this.”
    “This is a small model, but even so, it’s much larger inside than any other ship of this size.”
    “How can that be? You are making fun of my ignorance.”
    “No, no. I’m serious. This is one of the first ships to be completely graviticized.”
    “What does that mean? -But please don’t explain if it requires extensive physics. I will take your word, as you took mine yesterday in connection with the single species of humanity and the single world of origin.”
    “Let’s try, Professor Pelorat. Through all the thousands of years of space flight, we’ve had chemical motors and ionic motors and hyperatomic motors, and all these things have been bulky. The old Imperial Navy had ships five hundred meters long with no more living space in them than would fit into a small apartment. Fortunately the Foundation has specialized in miniaturization through all the centuries of its existence, thanks to its lack of material resources. This ship is the culmination. It makes use of antigravity and the device that makes that possible takes up virtually no space and is actually included in the hull. If it weren’t that we still need the hyperatomic-“
    A Security guard approached. “You will have to get on,
