Nice to see this again. Such a clear breakdown of a complex topic, presented beautifully.

Tangentially related, the documentary The Watchmaker's Apprentice [0] is a captivating look at the dedication it takes to create a mechanical watch. It's amazing that it's possible for a single person to craft each tiny cog and spring from scratch and put it all together.
