That was a super long post to just say “the ratio of mph/knots ≈ π/e … and it’s not very useful, but a cool coincidence.”

- Philpax 2y agoIt's about the journey, not the destination.
- tiffanyh 2y agoThere’s not much of a “journey” though … because both mile and knot are just arbitrary assigned measurements. ——- mile = 1,000 paces (as defined by Romans) knot = how many logs would pass by in 30 seconds. There’s no mathematical reason why their value is what it is. Unlike π and e that do.
- ianburrell 2y agoThe nautical mile came first. It is one minute of longitude or latitude at equator. The speed was measured with knots at specific lengths.
