As Ms. Sobel puts it, ''He wrote with the scrivener's equivalent of marbles in his mouth.'' Describing his first encounter with a potential patron of his work, he wrote, ''Mr. Graham began as I thought very roughly with In the same format as his Newbery Honor title The Great Fire (1995), Murphy brings the blizzard of 1888 to life. He shows how military weather-monitoring practices, housing and employment conditions, and politics regarding waste management, transportation monopolies, and utilities regulation, all contributed to—and were subsequently affected by—the disaster. He does so through an appealing narrative, making use of first-hand accounts whose sources he describes in his notes at the end (though, disappointingly he cites nothing directly in the text). The wealth of quotable material made available through the letters of members of “the Society of Blizzard Men and Blizzard Ladies” and other sources help to make the story vivid. Many drawings and photographs (some of the blizzard, but most of related scenes) illustrate the text. These large reproductions are all in a sepia-tone that matches the color of the typeface—an effect that feels over-the-top, but doesn’t detract significantly from the power of the story. Murphy’s ability to pull in details that lend context allows him to tell this story of a place in time through the lens of a single, dramatic episode that will engage readers. This is skillfully done: humorous, jaw-dropping, thought-provoking, and chilling.

Hay que pensar en la longitud como un elemento asociado al tiempo. Si tenemos en cuenta que circunvalar la Tierra supone 360º, que se dividen en 24 meridianos de longitud, obtenemos una separación entre ellos de 15º, calculándose cada grado en minutos. Por lo tanto es fundamental saber en todo momento el tiempo real tanto en el barco como en el lugar desde el que se ha partido o el de destino. Parece simple, con un simple reloj arreglado. Pero no es tan fácil como parece, porque la temperatura y la presión atmosférica afectan mucho la maquinaria de los relojes, adelantándolos o retrasándolos o simplemente parándolos. El capitán pensaba que estaba a X minutos de su destino y se encontraba con que el tiempo pasaba y no arribaban a lugar alguno. Y aquí entraban en juego los partidarios de los relojes y los que preferían guiarse por el mapa estelar, mirando el cielo. Nearly 100 years later, Galileo Galilei discovered Jupiter. He carefully observed the moons of Jupiter, calculated their movement periods and sketched Astronomical Ephemeris. He also created a navigation helmet, the celatone. It resembles a gas mask made of copper and can be used to observe Jupiter’s moons to determine longitude. This method was generally accepted upon its introduction. However, unfortunately it was limited to being used on land, and still did not work on turbulent seas. Since the days of Ptolemy, legendary scientific and exploratory minds like Amarigo Vespucci, Sir Issac Newton and Galileo Galilei did a lot of research into this matter but it took sixteen more centuries for mankind to finally invent a reliable solution for this problem.Our protagonist, John Harrison, was born into modest means. He was a carpenter by trade. Where Harrison developed the skills necessary to eventually create his chronometers is murky. What we know is that he was 21 years old when Parliament announced the Longitude Act. He undertook the challenge and had the rest of his life ahead of him to devote to the problem, which he did.

This link is for John Harrison and Son's H5, made in 1770: An amazing book following the attempts to solve the longitudinal navigation problems. The author’s research covered several hundred years of partial success and many failures. Especially interesting was the English contest for solving the problem. An amazing man, John Harrison, worked tirelessly to conquer the problem. The trials of Harrison, and the jealously of others in his attempts made for a good story.. This genius is credited with producing the first marine machine to accurately calculate longitude. Then he reduced his machine to a marine watch. He made numerous chronometers and many of them may be seen in the Royal Observatory and other places in England.
