Economist.com | Cosmology

Economist.com | Cosmology: "IT WAS beautiful, complex and wrong. In 150AD, Ptolemy of Alexandria published his theory of epicycles�the idea that the moon, the sun and the planets moved in circles which were moving in circles which were moving in circles around the Earth. This theory explained the motion of celestial objects to an astonishing degree of precision. It was, however, what computer programmers call a kludge: a dirty, inelegant solution. Some 1,500 years later, Johannes Kepler, a German astronomer, replaced the whole complex edifice with three simple laws."

Interesting stuff. I agree, I think we've just got some variables wrong (although my opinion carries very little weight). More reading before a full post.
