... 6. A way to find beauty in physics and math • If physics can explain something musical then physics is beautiful. Pythagoras showed that musical intervals were related to rational numbers (like 2/3) • If a physical model resembles an acoustic system it’s more beautiful and therefore better. (Kepler ...
