Product Description

Amazon.co.uk Review

The thorniest scientific problem of the 18th century was how to determine longitude. Many thousands of lives had been lost at sea over the centuries due to the inability to determine an east-west position. This is the engrossing story of the clockmaker, John "Longitude" Harrison, who solved the problem that Newton and Galileo had failed to conquer, yet claimed only half the promised rich reward. --Amazon.com

Review

Dava Sobel has written a gem of a book!one of the best reads for the non-scientific writing to come along for many a moon." Financial Times "A true life thriller, jam-packed with political intrigue, international warfare, personal feuds and financial skullduggery." Daily Mail "Rarely have I enjoyed a book as much as Dava Sobel's Longitude. She has an extraordinary gift of making difficult ideas clear." Daily Telegraph --This text refers to an alternate Paperback edition.

5.0 out of 5 stars Anniversary edition of a surprise best seller, 10 Oct 2005
By 
Budge Burgess (Kilmarnock, Scotland) - See all my reviews
(TOP 500 REVIEWER)   
Dava Sobel's description of the search for an accurate means to measure longitude was a surprise best seller when first published. This latest, celebratory edition is prefaced by an introduction by Neil Armstrong. Does it add to the package?

Sobel took what was once an intractable problem - finding a means to work out precisely where you are - and turned it into a very readable account, making the history and science readily accessible to a popular readership. Working out latitude is not particularly difficult - the equator is a fixed point and observation of sun, stars, and length of day make it relatively easy to determine how far north or south you are.

But longitude? Because the earth spins (more or less) on a north/south axis, the two poles act as fixed points in space. There are no such fixed points on the equator - every point on the equator undergoes a complete revolution every twenty four hours. Longitude has always been problematic, and for the seafarer, that problem could easily prove fatal.

The solution came in the creation of clocks which would keep good enough time at sea, and the man responsible for their invention, Harrison, emerges from Sobel's book as a determined, driven man.

It's a fascinating little book, written in a highly accessible style. It's quite a quick read. It's a highly enjoyable read. It's also a stimulating read, and must have encouraged a few people to delve further into history and science.

But does it deserve a new edition? Well, the cachet of Armstrong's introduction is a reminder that long distance sea travel was once as dangerous as current space travel. It's unnecessary. Sobel's story is exciting enough, and will absorb you with or without an introduction. It remains an excellent little volume and a worthy publishing success - maybe it's time you read it again!

4.0 out of 5 stars Make time to read this, 15 Mar 1999
By A Customer
This review is from: Longitude (Paperback)
While Longitude is, on the surface of it, a book about scientific endeavour, its appeal is due to the story of a man's struggle against the prevailing thought of the time and the board set up to judge the award for the discovery of a method of determining longitude which was full of people with vested interests. The determination and drive of Harrison is awesome; if it was a novel you would find it difficult to believe. This is arguably the one book that has driven the much quoted trend towards science based books. While the media asks if this signals renewed interest in things scientific, the real answer is more likely that stories such as this are successful because they are about real people with real obstacles to overcome. Well worth a read; it won't take you long!

5.0 out of 5 stars What a great little book!, 8 Nov 2003
This review is from: Longitude (Paperback)
Just to prove that the most wonderful stories can be produced from true life, this science book for the layman tells the irresistable tale of John Harrison, winner of the English Parliament's prize for the determination of longitude in 1770.

This is a tiny book in the paperback version, and makes for a rapid but extremely satisfying read. Political intrigue, fascinating science and excellent incidental anecdotes abound. (My favourite occurs right at the beginning - the tale of a haughty admiral who has an uppity sailor hanged for daring to question his navigation, and who receives his comeuppance in the most deliciously ironic way.... and it's all true!)

Most of all, it brings into focus the concept of a "life's work" - John Harrison's dogged faithfulness to producing the world's most accurate chronograph in a practical, portable package. The sheer thought of spending 19 years perfecting just one variation of it is inconceivable; that he spent over 40 years refining his concept to the eventual prizewinning piece just boggles the mind.

This is a delightful read.
