In 1841, while browsing in a Cambridge bookshop, a young English student named John Couch Adams happened upon a perplexed remark in an astronomical report on the erratic behavior of the planet Uranus. A gifted mathematician, Adams set about arriving at an explanation, commenting to a fellow student, "You see, Uranus is a long way out of his course. I mean to find out why." Eventually, he did, using not direct observation but, controversially, mathematical modeling of a sort that has become commonplace today. Adams's work, built in a close race against rival French scientist Urbain Le Verrier, eventually established that Uranus's path was influenced by the gravitational pull of the then unseen planet of Neptune; Standage credits both Adams and Le Verrier with its discovery.

Drawing on long-forgotten archives, including a scrapbook by the author of the remark that fired Adams's imagination, science correspondent Tom Standage serves up a fine tale of discovery. His story begins with the earliest scientific descriptions of Uranus, an annoyingly wayward planet whose "position in the sky obstinately refused to match up with the position predicted by theory"--the classical theory, that is, of a regular, clockwork universe, which obtained in Adams's day and would not quite be laid to rest until Einstein's time. Standage's story continues to the present, an era when astronomers are, it seems, discovering new planets at every turn. Thanks to Adams and Le Verrier, Standage writes at the end of this graceful book, "Uranus lit the way to Neptune--and Neptune now points the way to the stars." --Gregory McNamee

From Publishers Weekly

At a time when new extra-solar planets are announced monthly, Standage (The Victorian Internet) recounts an extraordinary tale of the confluence of great scientific and mathematical investigation and talent, as well as personal and national rivalries, which produced both a momentous discovery and enough embarrassment to cloud the careers of several distinguished astronomers. The protagonist is mathematical prodigy and Cambridge University astronomy graduate student John Couch Adams, who in 1845 completed a detailed calculation of the orbit of an unseen planet based on its supposed gravitational effects on Uranus. To put the enormous originality of Adams's hypothesis into proper perspective, Standage actually begins his account with the discovery of Uranus in 1781, considered inexplicably unruly in its movements and thus an anomaly among planets. Applying the fresh approach of mathematics to this conundrum, Adams calculated exactly where another planet, soon to be known as Neptune, was in the solar system. England's astronomer royal, George Airy, as well as Adams's own observatory director, James Challis, although intrigued, did not endorse Adams's theory until Airy began corresponding with a French mathematician named Urbain Le Verrier, who shared Adams's belief. This finding ignited Airy's desire not to let England lose out to France in what could be a monumental breakthrough. On August 12, 1846, Challis spotted but did not recognize Neptune and missed earning Adams and himself credit for the discovery, which went ultimately to an astronomer in Berlin. Standage, science correspondent at the Economist, gives a colorful account of the Neptune affair. Both astronomy buffs and armchair explorers will revel in his tale. Illus.

The story of the discovery of the planet Neptune is one of the most fascinating in the era of modern astronomy. Kepler's laws of planetary motion and Newton's unprecedented mathematical description of the law of universal gravitation allowed predictions of planetary positions to an accuracy of arcseconds.
In view of this successful mathematical description, Uranus' misbehavior was so bad that it was proving to be a continual embarrassment to astronomers, and the drive to find a solution was strong in the early to mid 19th century. The story of Adams in England, Le Verrier in France, and Galle in Germany has been told many times, and will be familiar to fans of the history of astronomy. Standage's retelling of the story is a good read, but probably adds little to Grosser's 'The Discovery of Neptune' (1962). An interesting facet Standage adds to the picture has to do with the title of his book. The 'file' in question belongs to George Airy (a notoriously fastidious record keeper). It contained correspondence, news clippings, etc., on the issue of the discovery of Neptune. Conspiracy theorists abounded in the years after the discovery, and some made the claim that Airy was in cahoots with Le Verrier in suppressing Adams' work to ensure that the credit would go to the Frenchman. Apparently Airy's file disappeared at some point during the last 20 years or so, renewing the conspiracy theorists' energies. Standage informs us late in his book that the file eventually turned up among the papers of a recently deceased former astronomer of the Greenwich Observatory. Examination of the file proved that there was no collusion.
This incident deserves further mention. Standage does not name the astronomer who had the file, nor the circumstances under which it was 'borrowed.

Tom Standage's The Neptune File is an account of the simultaneous discovery of the planet Neptune in 1846 by two mathematicians, John Couch Adams and Urbain Jean-Joseph Le Verrier, as well as the subsequent controversy over their rival claims. Adams and LeVerrier used different mathematical methods to predict the position of the planet based upon perturbations in the orbit of Uranus, marking the first time the position of a planet was deduced rather than fortuitously discovered. Unfortunately, when the planet was actually sighted based on the predictions, this led to a situation where both mathematicians had a simultaneous stake in the discovery and a international uproar resulted as France and England pressed their representative's rival claims. While the actual material on Neptune itself is perhaps a little too lean to bear an entire book, Standage sets his story carefully in context, taking us through the entire history of planet hunting, from the chance discovery of Uranus to recent discoveries of extra-solar planets, peppering the story with lively sketches of all the important figures, as well as anecdotes, theories, and predictions. The Neptune File is both accesible, intelligent popular science and an interesting account of the personalities involved in the discoveries that pushed back the frontiers of the universe from the 18th to the 20th centuries.

You might expect planet Neptune’s discovery to be worthy of a footnote, or a magazine article at most. Yet Tom Standage manages to bring alive a fascinating story with an entertaining cast of characters from the late 19th century around this discovery.

Man has known about the first six planets since ancient times. They’re bright enough to be seen with the naked eye, and their movements across the sky clearly distinguish them from the stars.

Searching the sky with his advanced (for the time) telescope, amature astronomer William Hershel discovers a seventh planet, Uranus, in 1781. This created a sensation among astronomers, and opened up the possibility of more planets in the sky.

While trying to compute the precise orbit of Uranus, astronomers noted something wasn’t quite right. It was speeding up and slowing down from where it was expected to be. Two astronomers, the brash Frenchman Urbain Le Verrier and the quiet Englishman John Adams begin undertaking the complex calculations to try and predict where the new planet should appear.

With the calculations underway, the race is on to actually find the new planet, an amazing achievement with 19th century technology. The acrimony and infighting resulting from the discovery also makes for a great story.

I actually picked up this book in a used bookstore and read the back cover. The facts surrounding the discovery of the planet were new to me. (Kind of embarrassing really that I had never heard it before. Remind me to contact the secondary school I attended!!) In any event, I was enamored by the discriptions on the back cover and bought it for around four or five bucks. I read it in less than a day, which for me is an extreme rarity. I usually spend my time in the "shallow end" of the literary pool, reading books that can only be described as "easy" reads. This is one of the most entertaining books I've read in years. Unfortunately, I lent the book to someone who had more of a background in astronomy who must have known the book's true value and I haven't seen the book (or the guy) since. So I'm back here to purchase another copy. This time I am much more certain of my investment.
