When we asked for suggestions for happier history stories not long ago, we got a fair number of responses that were closer to "deeply upsetting" than "sunshine and unicorns" on the subject spectrum. Fortunately, Randy not only suggested longitude, but he also followed it with eight exclamation points. While not a 100 percent happy story, the story of longitude, and of European efforts to figure out how to calculate it, features inventions, clocks and shipwrecks - but mostly their prevention, not their carnage and loss. So: Randy wins.
