Fredric Brown was an American science fiction and mystery writer. He was one of the boldest early writers in genre fiction in his use of narrative experimentation. While never in the front rank of popularity in his lifetime, Brown has developed a considerable cult following in the almost half century since he last wrote. His works have been periodically reprinted and he has a worldwide fan base, most notably in the U.S. and Europe, and especially in France, where there have been several recent movie adaptations of his work. He also remains popular in Japan.
Never financially secure, Brown - like many other pulp writers - often wrote at a furious pace in order to pay bills. This accounts, at least in part, for the uneven quality of his work. A newspaperman by profession, Brown was only able to devote 14 years of his life as a full-time fiction writer. Brown was also a heavy drinker, and this at times doubtless affected his productivity. A cultured man and omnivorous reader whose interests ranged far beyond those of most pulp writers, Brown had a lifelong interest in the flute, chess, poker, and the works of Lewis Carroll. Brown married twice and was the father of two sons.
Experiment is both Frederic Brown and the short story at their best: Taut, humorous and thought-provoking, it deals with the paradoxes of time travelling.
What happens when you change your will only in order to create a time paradox? The story gives a rather stunning answer which I did not analyze too closely for fear of following the professors and the universe …
“The first time machine, gentlemen,” Professor Johnson proudly informed his two colleagues. “True, it is a small-scale experimental model. It will operate only on objects weighing less than three pounds, five ounces and for distances into the past and future of twelve minutes or less. But it works.”
The small-scale model looked like a small scale—a postage scale—except for two dials in the part under the platform.
Professor Johnson held up a small metal cube. “Our experimental object,” he said, “is a brass cube weighing one pound, two point three ounces. First, I shall send it five minutes into the future.”
He leaned forward and set one of the dials on the time machine. “Look at your watches,” he said.
They looked at their watches. Professor Johnson placed the cube gently on the machine’s platform. It vanished.
Five minutes later, to the second, it reappeared.
Professor Johnson picked it up. “Now five minutes into the past.” He set the other dial. Holding the cube in his hand he looked at his watch. “It is six minutes before three o’clock. I shall now activate the mechanism—by placing the cube on the platform—at exactly three o’clock. Therefore, the cube should, at five minutes before three, vanish from my hand and appear on the platform, five minutes before I place it there.”
“How can you place it there, then?” asked one of his colleagues.
“It will, as my hand approaches, vanish from the platform and appear in my hand to be placed there. Three o’clock. Notice, please.”
The cube vanished from his hand.
It appeared on the platform of the time machine.
“See? Five minutes before I shall place it there, it is there!”
His other colleague frowned at the cube. “But,” he said, “what if, now that it has already appeared five minutes before you place it there, you should change your mind about doing so and not place it there at three o’clock? Wouldn’t there be a paradox of some sort involved?”
“An interesting idea,” Professor Johnson said. “I had not thought of it, and it will be interesting to try. Very well, I shall not …”
There was no paradox at all. The cube remained.
But the entire rest of the Universe, professors and all, vanished.
Paradoxes are called paradoxes for a reason; and that reason is that if they weren't paradoxes they wouldn't be called paradoxes because that would be a paradox.
