Ptolemy (kit) §

Ptolemy was a Greek guy living in Alexandria, Egypt, where the biggest library in the world was.

And so what did Ptolemy do? He read…and he looked at the stars a lot.

All that reading and all that staring at the stars led to something massive. He assembled and created a unified theory of the cosmos called 150 - The Almagest. This text was so good, it was treated as 100% accurate for 1500 years!

Even after Copernicus published his heliocentric theory in 1543, it took another century until Kepler overcame his deeply ingrained beliefs. Kepler didn’t think outside the box, he thought outside the circle.
