Wow, are we criticizing Ptolemy now?
He predicted the Earth was round and that there was planetary motion involved.
But let's go back to the basics. How about Archimedes' Sand Reckoner, in which the Earth revolves around the Sun? Completely wrong, huh? He was even close when he tried to calculate the distance to the Sun. While Ptolemy's theory had no mathematics at all, just circles in the sand, Archimedes provided the numbers too. He even tried to predict the number of grains of sand in the universe. And how about this:
The total number of nucleons in the observable universe of roughly the Hubble radius is the Eddington number, currently estimated at 10^80. Archimedes' 10^63 grains of sand contain 10^80 nucleons, which means that Archimedes' number equals Eddington's number
