Catenary Tails
- How did you find PF?
- DuckDuckGo led me to a stimulating thread whose OP is searching for the most accurate derivation of the precession of nodes of the lunar orbit. Isn't that how everybody got here?
During the pandemic I've been responding to a lot of commentors of YouTube science and math channels with clarifying explanations to their basic questions that won't likely get answered by the content creator. Or I provide interesting comments related to the videos intended to amplify the sense of awe and wonder of a given science or math topic, typically infused with a dissembling and witty sense of humor. But a more direct and widely accessible venue will be more satisfying, and PF looks like a good place to contribute.
