The PBS science program "NOVA" produced a television documentary called "Lost At Sea — The Search for Longitude," which was based on Ms. Sobel's book. Granada Films of England created a dramatic version of the story, "Longitude," starring Jeremy Irons and Michael Gambon, which aired on A&E as a four-hour made-for-TV movie. A two-hour "NOVA" documentary based on Galileo's Daughter, called "Galileo's Battle for the Heavens," first aired on public television in October 2002, and won an Emmy in the category of historical programming. The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." One can only look at watches for so long before the obsession requires other inputs. Recommended by my father, Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time by Dava Sobel ended up being exactly the watch-adjacent content I was looking for. It’s a book about ingenuity, dedication, betrayal, eventual triumph, and a great deal of hard-earned money. John Harrison is the father of marine chronometers, the precise timing instruments that allowed ships from the 1700s into the 1900s to navigate by longitude. Without Harrison and his chronometers, Great Britain would not have had the success it did in establishing and maintaining its empire, making one British astronomer’s personal vendetta against Harrison and his chronometers all the more damning. Over time other ladies joined the group, thanks to the director’s farsighted hiring practices and the introduction of photography to astronomy. Instead of observing through the telescope by night, the women could analyze the stars in daylight on glass photographic plates. Harvard's female workforce grew accordingly, and its individual members won national and international acclaim for their discoveries.

La Historia está llena de pequeños descubrimientos capaces de cambiar el mundo. Aunque debería decir pequeños vistos desde nuestros días. Este es el caso de la longitud, es decir, esas líneas imaginarias que trazan nuestro planeta desde los polos, dividiéndolo en veinticuatro partes iguales. La longitud era fundamental en tierra firme para trazar mapas lo más exactos posibles, pero sobre todo era esencial para la navegación. El mundo era un gran desconocido cuyos horizontes estaban todavía por descubrir y el único medio para hacerlo era en barco, surcando esos océanos y mares ignotos donde cualquier error de cálculo podía suponer perderse en su inmensidad y morir con seguridad, ya sea por la escasez de agua potable y alimentos como por escorbuto. Un barco podía pensar que estaba arribando a su destino cuando quizás era todo lo contrario, o podía colisionar con elementos desconocidos provocando su hundimiento. John Harrison's marine timekeepers are on display at the Royal Observatory in Greenwich, London and are well worth seeing... The inability to solve the longitude problem for so long also had dire consequences. If a ship didn't know how far to the east or west it had traveled, then it didn't know where land was likely to be, and the unexpected contiguity of land had

You might think that Harrison's incredible devices would be unanimously welcomed. Alas, no. He was forever battling vested interests until eventually, and after decades, King George III intervened. For the rest of his life, Harrison would devote himself to developing his chronometers and solving the longitude problem.Determining latitude was relatively easy in that it could be found from the altitude of the sun at noon with the aid of a table giving the sun's declination for the day. Latitude can also be determined from night sightings of Polaris, the northern pole star. Would I teach it? Not in an English class, but I'd refer to it as a great example of science writing. Era tan importante para los países encontrar una solución al problema de la longitud, que les hacía perder barcos, mercancías, hombres y dinero, que decidieron poner una recompensa a aquél que diese una solución lo más exacta posible. El gobierno inglés llegó a ofrecer 20.000 libras, el equivalente a varios millones en la actualidad, estableciéndose así el Decreto de la Longitud de 1714.

I don’t use it that much personally, because I don’t tend to go anywhere, but I’m sure all this technology I love to use makes use of GPS. Thanks to GPS, we can forget that calculating longitude without the help of a network of satellites is difficult and requires great mathematical and engineering expertise. GPS might not be great at giving directions, but that doesn’t mean you’re lost. Dava Sobel is an accomplished writer of popular expositions of scientific topics.
