Using Moiré Patterns to Guide Ships
- colemannugent 9y agoRecognized this from the Tom Scott video a month ago. If your not subscribed to him I highly recommend it. Every video he makes is interesting.
- hartror 9y agoAgreed. Tom Scott is an excellent yt'er.

- oh_sigh 9y agoI usually like Tom Scott's videos, but my main takeaway from that video is that, as far as I can tell, he did not consult a single subject matter expert(harbor pilot, captain, longshoreman, lighthouse keeper, so on) on the matter. Maybe it makes for more fun videos when you play up a mystery by only asking questions to people who you know won't know the answer, but it was a pretty pathetic research attempt on his end.

- baud147258 9y agoThis one is weird, since he usually find sources that seem accurate, most of the time people working on what he's talking about. Perhaps he did not search hard enough that time.

- Terr_ 9y agoPerhaps a bit of a leap here, but I'm reminded of hyperbolic navigation [0] systems used for ships in WWII. In both cases information is derived from the combination of two different regular patterns... one just happens to be radio.
