"LONGITUDE" - Dava Sobel (US/UK 1996)
I found this minor gem in a passing Op Shop. Cost me a buck.
Subtitled "The True Story of a Lone Genuis Who Solved the Greatest Scientific Problem of His Time", this is a fascinating (to me at least!) journey, or I should say voyage, through a quest for a specific kind of knowledge - the knowledge of how they answered - "Where the hell ARE we!"
In the 1700s (and some time before), with the help of published tables, sea captains calculated their latitude - position North-South - by measuring the angle of the sun at local noon, or by observing the North Star (Polaris) at night using a sextant. But they struggled to know where they were East-West - their Longitude.
As recent as 1707, coming home to England from Gibraltar in foggy stuff he described as "dirty weather", an Admiral's war fleet in line ahead ran into the Scilly Isles (that scraggy chain that hangs off Lands End) with the loss of the first four ships and 2,000 soldiers. And that was after he'd summoned, with good reason, every navigational brain he had at his disposal.
As it turned out the Admiral was one of only two that washed up alive, only to be murdered on the beach by a passing female chancer who badly needed his emerald ring! The other twist - some well-meaning able seaman who - as it turned out - had a better idea than any of them where they were, made the mistake of saying as much to an officer, and was promptly hanged for mutiny! Not the done thing to question your betters out loud. Geez, did HE have the last laugh!
Suffice to say, with a few centuries till GPS came along, Brittania and the rest of the European Empire-chasers of the day badly needed a better way to reliably calculate their East-West position at sea in all weathers, hot or icy, by night and day. A "Board of Longitude" was set up and a 20,000 pound (say five million quid today) prize to encourage ideas.This is the hard won story of how John Anderson, a self-taught Yorkshire carpenter and amateur clockmaker, over some 20-30 eventful years, came up with the solution, with all the politics and rivalries and back-stabbing of the day against him. AND he cracked it with a "chronometer" made mostly of wood! (The one shown is his first attempt).
Not everyone's riveting read, but I loved it. Appeals to my - something. Sense of justice? The small guy overcoming the odds? Whatever. You can do worse than find a copy.
Cheers....
