"He knows perfectly well what he's saying, and it probably scares him more than it does you. The difference is that he's willing to face it and you aren't." The difference was that Faress was a scientist and Dandrik was a science teacher. To Faress, a new door had opened, the first new door in eight hundred years. To Dandrik, it threatened invalidation of everything he had taught since the morning he had opened his first class. He could no longer say to his pupils, "You are here to learn from me." He would have to say, more humbly, "_We_ are here to learn from the Universe." It had happened so many times before, too. The comfortable and established Universe had fitted all the known facts--and then new facts had been learned that wouldn't fit it. The third planet of the Sol system had once been the center of the Universe, and then Terra, and Sol, and even the galaxy, had been forced to abdicate centricity. The atom had been indivisible--until somebody divided it. There had been intangible substance that had permeated the Universe, because it had been necessary for the transmission of light--until it was demonstrated to be unnecessary and nonexistent. And the speed of light had been the ultimate velocity, once, and could be exceeded no more than the atom could be divided. And light-speed had been constant, regardless of distance from source, and the Universe, to explain certain observed phenomena, had been believed to be expanding simultaneously in all directions. And the things that had happened in psychology, when psi-phenomena had become too obvious to be shrugged away. "And then, when Dr. Dandrik ordered you to drop this experiment, just when it was becoming interesting, you refused?" "Your Majesty, I couldn't stop, not then. But Dr. Dandrik ordered the apparatus dismantled and scrapped, and I'm afraid I lost my head. Told him I'd punch his silly old face in, for one thing." "You admit that?" Chancellor Khane cried. "I think you showed admirable self-restraint in not doing it. Did you explain to Chancellor Khane the importance of this experiment?" "I tried to, Your Majesty, but he simply wouldn't listen." "But, Your Majesty!" Khane expostulated. "Professor Dandrik is head of the department, and one of the foremost physicists of the Empire, and this young man is only one of the junior assistant-professors. Isn't even a full professor, and he got his degree from some school away off-planet. University of Brannerton on Gimli." "Were you a pupil of Professor Vann Evaratt?" Prince Travann asked sharply. "Why, yes, sir. I----" "Ha, no wonder!" Dandrik crowed. "Your Majesty, that man's an out-and-out charlatan! He was kicked out of the University here ten years ago, and I'm surprised he could even get on the faculty of a school like Brannerton, on a planet like Gimli." "Why, you stupid old fool!" Faress yelled at him. "You aren't enough of a physicist to oil robots in Vann Evaratt's lab!"
