Ptolemaic system

Interesting thought on how current cultural values may influence how we see the world around us.

The Greeks were stubborn in believing that the stars and planets all had circular paths. It was their belief that heavenly bodies would take the most “perfect” path possible–that of a circle.

And when there were observational discrepancies with this theory, the Greeks would (instead of giving up on the circle idea) think of another supplemental theory to justify the discrepancies!


Hopefully this is a reminder that sometimes the greatest breakthroughs come from actually breaking through cultural norms.

Beauty in math

This is the famous astronomical clock in Prague! It tells the position of the moon, sun, and time of day. Without the context, it might even look like some abstract art masterpiece. I think this is an awesome intersection of two of my classes this semester–art and astronomy!
