In September of 1859, the entire Earth was engulfed in a gigantic cloud of seething gas, and a blood-red aurora erupted across the planet from the poles to the tropics. Around the world, telegraph systems crashed, machines burst into flames, and electric shocks rendered operators unconscious. Compasses and other sensitive instruments reeled as if struck by a massive magnetic fist. For the first time, people began to suspect that the Earth was not isolated from the rest of the universe. However, nobody knew what could have released such strange forces upon the Earth--nobody, that is, except the amateur English astronomer Richard Carrington. In this riveting account, Stuart Clark tells for the first time the full story behind Carrington's observations of a mysterious explosion on the surface of the Sun and how his brilliant insight--that the Sun's magnetism directly influences the Earth--helped to usher in the modern era of astronomy. Clark vividly brings to life the scientists who roundly rejected the significance of Carrington's discovery of solar flares, as well as those who took up his struggle to prove the notion that the Earth could be touched by influences from space. Clark also reveals new details about the sordid scandal that destroyed Carrington's reputation and led him from the highest echelons of science to the very lowest reaches of love, villainy, and revenge. The Sun Kings transports us back to Victorian England, into the very heart of the great nineteenth-century scientific controversy about the Sun's hidden influence over our planet.… (mehr)

Not bad, although the subtitle (“The Unexpected Tragedy of Richard Carrington and Tale of How Modern Astronomy Began”) is misleading. Richard Carrington is a major character but not the whole subject of the book, and it’s not about how modern astronomy began, or even about how solar astronomy began, but about the discovery of the relation between sunspots and space weather.

Longitude author Dava Sobel gets a cover blurb, and I suspect The Sun Kings was inspired by the success of her book. The general idea is similar; the British government sponsors research into a navigational problem (measurement of longitude versus reasons for periodic and long term compass deflection); a colorful cast of characters takes on the problem; and it’s eventually solved/explained. Carrington’s role was divided between the tedious but necessary grunt work of astronomy – careful observations and measurement of sunspots – coupled with the kind of luck that favors the prepared mind: the first recorded observation of a white-light solar flare. His tragedy was largely self-inflicted. First he alienated a number of professional astronomers by becoming convinced that the government owed him a paid position (to be fair, he was much more deserving of such a position than many of the successful job seekers); then he became obsessed with and married a much younger woman (whom he’d met walking on the street), Rosa Rodway. Ms. Rodway, although illiterate (she had to make a “X” to sign the marriage license), was smart enough to accept the relatively wealthy Carrington’s offer, neglecting to mention that she was already married to a man who she claimed was her brother. Although Ms. Rodway frequently visited her “brother” and supported him with Carrington’s money, the setup came to a bad end; Ms. Rodway, now Ms. Carrington, eventually attempted to break off the arrangement whereupon her “brother” showed up and tried to stab her to death with a switchblade. She recovered and Carrington was forgiving, but apparently the aftermath was too much for both of them and they both died from chloral hydrate overdoses (author Stuart Clark calls this “chloral of hydrate” throughout, which makes no sense as chemical nomenclature).

The remainder of the solar astronomers discussed had rather less interesting lives. William and John Herschel, Heinrich Schwabe, Edward Maunder (who also married, but more happily, a much younger woman, Annie Russell, the first woman worker at the Greenwich Observatory), and George Ellery Hale are the major players and there are a host of minor ones. The science is well explained, with Clark emphasizing mistakes as well as progress; too many science histories make it seem like each new theory was immediately accepted while Clark shows that Kuhnian-style paradigm shifts were more likely.

The “villains” are also Kuhnian; two of the most prominent scientists of the era (George Airy and Lord Kelvin) dismissed the idea that the sun had any effect on the Earth’s magnetic field. Clark quotes Kelvin’s famous maxim that “if you can’t measure it you don’t know what you’re talking about”, but Kelvin proved (as he had previously done with Darwin) that you can measure something just fine and still not know what you’re talking about. In both cases, Kelvin made critical false assumptions; for Darwin, that the only source of solar energy was gravitational contraction, and that therefore the age of the Earth was much too short for organic evolution; and for Maunder, that the entire sun would need to be involved in observed magnetic “storms” and that the amount of energy necessary would be unreasonably large. Kelvin’s authority was such that Maunder, despite reams of statistics showing correlation between sunspots and magnetic storms on Earth, couldn’t overcome it.

Airy’s role was also negative although more benign. Like Kelvin, he had made a number of important contributions to science but, also like Kelvin, his authority as a scientist outlasted his ability. He was Astronomer Royal for 46 years, and it seems that his particular goal in the position was maintaining the Greenwich Observatory’s role as a purveyor of accurate star and planetary measurements rather promoting more theoretical research. He seems to have disliked both Carrington and Maunder – Carrington because he was “in trade” (he owned a brewery) and Maunder because he had never received a university degree but was appointed to Greenwich as the result of a competitive examination. In Carrington’s case, Airy apparently worked behind the scenes to ensure Carrington didn’t get the observatory appointment he wanted (Carrington wanted to sell his brewery and devote himself full time to astronomy, but couldn’t manage without at least a small salary). Airy’s influence on Maunder was less direct, but Maunder was reportedly terrified of him; he once dropped a bottle of photographic chemicals from the shock of turning around and finding Airy, in full Victorian frock coat regalia, had been standing behind him watching him work.

The illustrations are all contemporary; a drawing of exactly how a coronal mass ejection works would have been helpful. The index is sparse, and there are a lot of Web references in the bibliography (to be fair, many of them are to electronic versions of published papers). There are a couple of puzzling scientific lapses – the “chloral of hydrate” mentioned above, and the claim that William Herschel minimized the heat generated during solar observations by using a telescope with an unpolished mirror. Clark, who is the editor of a British popular astronomy magazine, has to know that won’t work; an unpolished mirror will not produce a sharp image. There’s a hint of what he might mean; silvering or aluminizing glass hadn’t been invented yet, so Herschel’s mirrors were made of speculum metal. Speculum metal tarnishes in air, so the mirrors had to be frequently repolished to remove the tarnish. I suspect this is what Clark means; Herschel then may have initially polished and figured his solar telescope mirror but then allowed it to tarnish to reduce the reflectivity. Oddly, a major contribution of John Herschel to solar observing, the Herschel wedge, isn’t mentioned.

It’s a fast and easy read, though, and there are more than enough interesting little facts about the history of sunspot and magnetic astronomy to make up for the minor flaws. ( )

A perfectly fine, but fairly unexceptional account of the scientific inquiries into the nature of sunspots and solar flares, beginning with Richard Carrington's observations of 1859. Would have benefited from better citations. ( )

While the overall story of the man who discovered the sunspots and their influence on the Earth was interesting, I found the writing to be a little dry. Good for someone who has an interest in astronomy... but not for a general reader. ( )

1859: un vascello americano si ritrovò nel mezzo di un'aurora astrale color rosso sangue. Nello stesso istante le cabine telegrafiche del mondo smisero di funzionare e l'unico uomo in grado di spiegare l'accaduto era Richard Carrington, astronomo dilettante, che dal suo osservatorio di Londra fu il primo testimone di un brillamento solare. E della più intensa tempesta magnetica che mai abbia colpito la terra. Partendo dalle storie personali degli scienziati dell'epoca, si ricostruisce uno dei momenti più significativi dell'astronomia.

The fascinating tale of the man who discovered the sun's magnetism and his struggle for acceptance in the scientific community. ( )
