jan 4, 1514 - Nicolaus Copernicus discovery - Earth orbits on its axis around the Sun
Description:
He omitted mathematical calculations for
the sake of brevity, but he confidently asserted that the Earth both revolved
on its axis and orbited around the Sun. This solved many of the problems
he found with Ptolemy’s model, especially the lack of uniform circular
motion.
