Instead: i wound up reading an autobiography disguised under the title "Is there anybody out there", a title which also disguises the fact that Drake spends more time and pages writting about the problems he encountered setting up SETI than SETI itself. Not to mention that he uses all 300 pages of his book to praise himself in a way that makes you yawn once you become familiar with the mechanism it is written. Indeed for a book that tackles an otherwise super interesting and controversial issue the book is boring. It's totally devoid of any humor and any attempts at such are further contributions to boredom. What's even more interesting is that for an author who clearly believes there is intelligent life out there he uses but a mere 2-3 pages to dismiss any accounts of aliens having already visited earth, recently or not so recently..2-3 pages to dismiss that? Hmmm, makes you wonder...In the end, after having (thankfully) been through with it i wound up thinking more about the motives behind Drake having written it than the book itself. Buy something else on the subject. Blindly.
Frank Drake is the person that the Drake Equation is named for. The Drake Equation a simple formula for calculating the change that other intelligence life in the Universe Exists. How you decide to plug numbers into the equation is where all the debate on this subject is conducted.
Great book. Get it if you can find it.

That might be because the first half of the book is far weaker than the second half--far less detailed than accounts I've read elsewhere of Galileo's early life prior to the publication of his controversial dialogue. The quoted letters from his elder daughter Maria Celeste are rather pedestrian.
The second half of the book compensates for these weaknesses. The reader starts to get a sense of Maria Celeste as a real person, and of the nature of her relationship with her father. The focus is still primarily on Galileo, but via Maria Celeste's no-longer-stilted letters and Sobel's writing, there's a view of Galileo that isn't seen in any other biography.
Ideally, read this and another of the Galileo biographies recommended by other reviewers. One book is not enough to fully explore all the aspects of this amazing man's life and work.
The difficult part of the book is the careful translation done in the archaic and overly polite language of the times, which makes for heavy going and loooong wordy passages at times.

If you are at all interested in the antecedents of today's accurate timekeeping devices this book is a must. The print quality is very high and the illustrations a wonderful aid to feeling the story unfold. The book does not contain detailed plans of Mr Harrison's chronometers or description of the techniques of celestial navigation, but rather is a brisk, engagingly written account of the origin of the Longitude problem, Mr Harrison's solution and those of his rivals and the political intrigues which delayed full acknowledgement of the merit of the H-1 to H-4 devices.
I bought this book some months after visiting the Old Royal Observatory in Greenwich, England. The ingenious mechanisms at work can keep an observer enthralled for hours. They are also very beautiful. "The Illustrated Longitude" really fills out the significance of the Longitude problem in that era and the career details and challenges overcome by a very clever and self made man.

As a result of the 1707-shipwreck story (with a loss of 4 out of the 5 ships), the English Parliament offered in 1714 a 20.000 pounds reward to the person that could provide a practicable and useful way of determining longitude. (If you have forgot, longitude is the "lines" that runs from pole to pole). Not being able to determining longitude was a great problem. Ships spent excessive time trying to find its way back to port, or worse men, ship and cargo were lost at sea.
John Harrison (1693-1776) spent his lifetime trying to solve the longitude mystery. Harrison was a son of a countryman, with minimal schooling, and was self-educated in watch making. He made several timepieces, which all qualified for the reward, but the reward was delayed several times by the Longitude committee whom believed that other ways of measuring longitude were the preferred ones. Ultimately after a lot of harassment and trouble, Harrison was given the reward money.
Dava Sobel has done a wonderful job in this book, capturing Harrison's fascinating character, his brilliance, preserving and hard working nature. The author has also managed to strike a perfect balance between technical jargon and personal anecdotes, and she does it in such a way permitting the lay readers of the book to admire the elegance of Harrison's discoveries. I believe it is a sign of excellent quality when an author makes learning so interesting.
I was hooked from the first page of this book and I read it in 50-page gulps at a time.
Highly recommended!
The man who "solved" (he died before his clocks were mass produced but his pioneering efforts were absolutely crucial) the problem was a carpenter and a watchmaker named John Harrison. His watches were among the most accurate in the history of time keeping. When he heard of the Longitude Act (the British government established a prize to anyone who could invent a usable and practical way of finding longitude at sea), Harrison set to work. His clocks were tremendously innovative; he solved the problems that plagued previous clocks on sea voyages (e.g. the metals in the clock would expand when in tropical climate and contact in Europe; these changes would render the clock unreliable). Harrison once built a clock that was almost entirely built of wood (with the exception of some brass parts); this clock never needed lubrication!
In the competition to win the £20,000 (roughly equivalent to several million modern American dollars), there were many quacks who advanced their various ideas but there emerged two dominant methods which vied for success. The clock method (How does this work? "To learn one's longitude at sea, one needs to what time it is aboard ship and also the time at the home port or another place of known longitude - at the very same moment. The two clocks enable the navigator to convert the hour difference into a geographical separation." Pages 4-5). However, this required a very precise clock and all clocks of the day were incapable of such precision. The other approach relied on the movement of the Moon relative to other celestial bodies. The astronomical approach continued to be championed by much of the scientific elite but it initially required four hours of calculations to determine longitude (this was eventually reduced to 30 minutes) and one had to have a clear sky (in order to see the Moon etc..) The Board of Longitude (which functioned as the Government body to determine who is to win the prize and give out grants to prospective men) subjected Harrison's various watches (he made four different ones, all different. The first three were very large and the last was about 5 inches in diameter) to many tests including observation at Greenwich Observatory, sea trials, disassembly before a panel of experts, reassembly and so on.
I found the intrigues of the various scientists interesting; it is not a phenomenon limited to the 20th century by any means. Harrison was looked down upon because he was what was called a "Mechanick," (i.e. a tinkering engineer) and the highly educated, academic astronomers did not think such a man capable of solving the vexing problem of longitude.
I have an interest in ships and their role in European empire building (e.g. the Dutch, French and British empires) and commerce and through reading this book I gained an appreciation of just how vital this piece of technology was to navigation in an age where radio and GPS were simply unavailable. Also, the idea of a Government sponsoring scientists to solve scientific problems (i.e. the concept of grants) seems to be pioneered here.
What not 5 stars? The technical descriptions of the mechanisms Harrison invented were difficult to visualize; some diagrams or even actual pictures of the devices would have been very helpful. I would also have liked to see some pictures of the various scientists involved.
Now that I read this book, I wished I had read it earlier as the events in the key inventor's life, John Harrison, tell a tremendous story for all innovators and inventors. Mr. Harrison, an unknown clock maker, solved one of the most critical problems of it's day, by looking to unconventional means to solve the problem. From Galileo to Newton, some pretty illustrious names can be found leading the charge to discover an accurate means of plotting longitude. The problem was so vital and strategic to naval superiority and dominance in commerce, that the British government funded a worldwide challenge for anyone that could discover how to determine longitude and prove that it accurately worked on a consistent basis.
While many of the world's leading scientists and astronomers were convinced that the only way to calculate longitude was from the movements of the stars and moons, Mr. Harrison created an extremely accurate timepiece and proved that his invention worked. Yet politics, greed and his own perfectist traits kept him from being recognized and awarded the grand prize...
I will highly recommend this book to my sons to read and to all my business associates that are so focused on bringing innovation to the market place, but spend too much time trying to perfect their ideas.
