An interesting observation that I may one day delve further into: Heliocentrism is the work of many men, but one made it popular against all odds by one. In his time, Copernicus faced the abuse of the Church and colleagues who couldn't admit or concede he was correct.
Much of the scientifically backed commentary being thrown about today - whether dealing with the earth's temperatures or economics - are full of voodoo theories and emotional conjecture. Much like Copernicus experienced, the momentum was against him. Even in today's age of science, we continue to choose theories that defy statistics, logic and a simple principle known as Ockham's Razor. For some reason, like in certain areas of religious dogma, we wish to hold to theories regardless of their consequences or reliability.
Copernicus, Galileo and men like them are heros. We could learn from them (again).
