Total aside, re: the chronometer, the 1750s definitely was not when it came into existence. He may have refined the design during that time, but the H1 chronometer was completed during the 1730s. I'm not sure if there's an exact date around for its completion.
- abecedarius 11y agoFWIW, I got that from https://en.wikipedia.org/wiki/1759_in_science https://en.wikipedia.org/wiki/1759_in_science (search for "H4").
- lmm 11y agoH4 was the one that was good enough, no?
- AnkhMorporkian 11y agoThe H4 was completed in 1761.
