You haven't seen numberphile and sixty symbols? Couldn't find the vid on those two symbols, but here's degrees and angular momentum. https://www.youtube.com/watch?v=eFS5Maa3bGY …https://www.youtube.com/watch?v=sy5NY-Dqdys …
Honestly I assumed that it’s because θ and φ are nice, round letters, very circular, good for angles. This is what I believe and you cannot change my mind.https://twitter.com/RadishHarmers/status/868385432354004992 …

The explanation in this video for why a bicycle stays upright is wrong. The wheels don’t have enough angular momentum to stop a bike from falling over. The rider continually makes small steering corrections to stay upright and on course.
