Did you know that, as recently as 1960, the theory of continental drift was rejected as scientific heresy? Did you know there are still people who believe vonDaniken and Velikovsky are right? Do you know who Charles Fort is?
The only connection those questions have is their place on the fringes of established science - yet the fringes of science are where the interesting discoveries frequently take place. Can any of us imagine a world in which continental drift is not a part of the established view of geology? Yet this was that world, only 40 years ago.
And who can forget Nikola Tesla? If it weren't for him, we wouldn't have any of the conveniences of modern society we take for granted. Alternating current, induction motors, radio, and all the technological advances based on them exist because of Tesla's genius.
