Predictions Done By One Man in The Past
Roger Bacon, a thirteenth-century Franciscan monk, predicted the following things in his Communia Mathematica:
High-speed sea travel. “It is possible to make machines of navigation,” wrote the erudite monk, “which need no man to navigate them, so that very large seagoing ships may go along with one man to steer, and at a greater speed than if they were full of men working them.”
The airplane. “Flying machines can be built so that a man sitting in the middle of the machine may turn an instrument by which wings artificially made will beat the air, like a bird flying.”
The automobile. “Cars could be made which move at inestimable speed without animals to draw them as if they were the chariots in which men fought of old.”
The microscope and telescope. “Instruments can be designed so that enormous things will appear very small and contrariwise...”
Gunpowder and bombs. “Sounds like thunder can be made in the air but more terrifying than those which occur in nature; for an appropriate material in moderate quantity, as big as a man's thumb, makes a horrible noise and shows a violent flash; and this can be done in many ways by which a whole town or army may be destroyed.”
