Been watching your videos for a while now. Excellent! Thank you

That is so nice, Thnx!

Excellent presentation on chronometer and its value in marine navigation. It is amazing how the craftsmen of 18th century clock-watch making were able to advance longitudinal marine navigation. I am a biological chemist. We know how van Leeuwenhoek, a lens-maker of the Dutch Golden Age, change our understanding of life by helping biologists see single-cell organisms. Society can only move forward and make everyone's life better by incentivizing everyone to advance their trade, free-market capitalism. As a result, watch makers advance marine navigation and lens-makers advance biology.

Great video

Crazy that the cheapest little casio is probably 10 x as accurate...(yes quarts i know....)

The clip could have mentioned, but didn't, that a GPS system requires timekeeping to a much greater degree of accuracy than even the best terrestrial navigation system. GPS satellites send time-tagged signals to receivers. The receiver calculates position by triangulating the distances with the four nearest satellites. That distance is determined by the difference in their time tags and is due to the different distances a radio signal must travel, at the speed of light, from one satellite to another.
This means the clocks on a GPS satellite must be _extremely_ accurate, stable, and precise. Each one therefore carries multiple atomic clocks. Even so, they must be synchronized once per day from the ground, since a large, controlled ground-based atomic clock is more stable than a smaller one in orbit.

American railroad pocket watches were leverset making accidental time setting impossible.

At last subtitles on english XD thx for that
