Longitude--#88 finished

 An interesting read about how to solve the problem of finding Longitude for boats on the ocean.  An interesting problem that became a priority when Britain ruled the seas after losing too many boats and sailors from hitting rocks because they didn't know where they were at.  It seems the scientists of the day mostly were looking to the sky and plotting stars and patterns to solve the problem.  A clockmaker developed a clock that was accurate even on the water/at sea.  Neither of these was an easy solution--both took decades to develop & fine tune.  While it seems the clock won out over time--the expense of the clock vs the sky & stars made it a closer race I guess.  I good read about an interesting problem & the solutions.

I have posted it on PBS, there was already 1 copy in system so who knows when/if ever it will move.
