Sometimes the basic assumptions we apply in pursuit of a goal get in the way of success.
Take astronomy. At one time in history, astronomers studied the way the planets revolved around the Earth in an attempt to create an accurate calendar.
But for centuries, it had been slightly off, every 100 years or so it would snow in July and the Pope would say, “Crank the calendar back six months.”
July would become January and the calendar would be correct again. But this put a real crimp in people’s vacation schedules and a better calendar had to be formulated.
Hence, astronomers enjoyed gainful employment.
The problem was that astronomers were laboring under a false model. The very definition of an astronomer’s job, one who studies the way the planets revolve around the Earth in order to create the perfect calendar, precluded them from finding the right answer.
