I’ve seen this before, and it’s a paragon of how to explain and demonstrate mechanical concepts.
This person needs to be hired by someone full time to produce this kind of page for all the things.
Thanks for reminding me it exists.

Truly incredible article

I have managed to lose track of time while reading about how we track time.

I love seeing this masterpiece of an article shared around. Really incredible stuff!
