A Dominant Character - Samanth Subramanian ****

When a science book does well in the mainstream press, the science content is often weak. In this biography of geneticist J. B. S. Haldane, Samanth Subramanian manages to get enough science in to make it worthwhile as popular science, but also piles on the biographical details, particularly on Haldane's political side, which unusually for a scientist dominated his life.

Haldane, it seems, was a classic posh boy who thinks he knows what's good for working folk - a communist who quoted the classics - and along with his irascible, blunt (well, rude really) personality, delight in shocking others and apparent enthusiasm for the dangers of warfare, comes across as a fascinating, if sometimes repulsive study (on the whole, Subramanian takes a more forgiving view, though without holding back on Haldane's faults).

Apart from his decades-long enthusiasm for the Soviet Union and ruthless (and fearless) approach to military life, we see how Haldane's science brought huge strides in the very early days of genetics, when they didn't yet really know what a gene was, but could deduce aspects of what was happening mathematically. In what was at the time a very descriptive science, Haldane always brought mathematical rigour. Although there's a bit of a dip in the book around the Spanish Civil War and the Second World War, where the writing droops a bit, generally this is put across in a truly engaging fashion - if it weren't for this dip, the book would get a solid five stars.

Subramanian has clearly put a huge amount of effort in, going into extravagant detail, such as checking bank statements, to uncover the minutiae of Haldane's life. It's a shame the same care wasn't applied to finding out about the University of Cambridge. At one point we read that Haldane's future first wife, Charlotte 'killed time, walking around the campus...' - despite living several years in Cambridge, I never found a campus. We are also told that the university did not award Haldane a fellowship at Trinity College - missing that that's down to Trinity, not the university. There is also a large chunk of the early part of the book on Haldane's father - certainly interesting in his own right, but too much for me: I wanted to get onto the subject. And though much of Haldane's science is covered, I would have liked some more exploration of what the science actually meant, perhaps at the expense of a touch less verbiage on his political life.

A good book then, to find out more about a figure that most who are interested in science will have heard of as a name, but probably without much appreciation of either exactly what his scientific work covered, or how much he was a dupe of Moscow for a significant part of his life. At one point in the 1940s, when Lysenko was destroying Soviet science (and scientists), Haldane took part in a BBC radio broadcast where he used weasel words to defend the Soviet stance, putting his politics above his scientific and humanitarian side. A flawed, interesting character who, despite at the time being up there with the big names of science internationally, is now largely forgotten by the general public in a way that far less substantial literary types of the period, such as the Bloomsbury set, aren't.

Review by Brian Clegg

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

Pagans (SF) - James Alistair Henry *****

There's a fascinating sub-genre of science fiction known as alternate history. The idea is that at some point in the past, history diverged from reality, resulting in a different present. Perhaps the most acclaimed of these books is Kingsley Amis's The Alteration , set in a modern England where there had not been a reformation - but James Alistair Henry arguably does even better by giving us a present where Britain is a third world country, still divided between Celts in the west and Saxons in the East. Neither the Normans nor Christianity have any significant impact. In itself this is a clever idea, but what makes it absolutely excellent is mixing in a police procedural murder mystery, where the investigation is being undertaken by a Celtic DI, Drustan, who has to work in London alongside Aedith, a Saxon reeve of equivalent rank, who also happens to be daughter of the Earl of Mercia. While you could argue about a few historical aspects, it's effectively done and has a plot...

Amazing Worlds of Science Fiction and Science Fact: Keith Cooper ****

There's something appealing (for a reader like me) about a book that brings together science fiction and science fact. I had assumed that the 'Amazing Worlds' part of the title suggested a general overview of the interaction between the two, but Keith Cooper is being literal. This is an examination of exoplanets (planets that orbit a different star to the Sun) as pictured in science fiction and in our best current science, bearing in mind this is a field that is still in the early phases of development. It becomes obvious early on that Cooper, who is a science journalist in his day job, knows his stuff on the fiction side as well as the current science. Of course he brings in the well-known TV and movie tropes (we get a huge amount on Star Trek ), not to mention the likes of Dune, but his coverage of written science fiction goes into much wider picture. He also has consulted some well-known contemporary SF writers such as Alastair Reynolds and Paul McAuley, not just scient...

I will take your word for it that he is largely forgotten by the general public. For those interested in population genetics, he is very much remembered for his part in laying down the groundwork of the subject, including numerical analysis of one of its most attractive examples, industrial melanism in the speckled moth

I remember coming across JBS as a kid in the late 60s via reading his children's book "My Friend Mr Leakey". Then I later found out hie was the son of JS Haldane when I was interested in the latter's work on respiratory physiology, inc dividing, mines, etc. I often quote JBS' famous quip about "If there is a God, he seems to have been inordinately fond of beetles"

Apart from the science and the politics JBS was an important science popularizer in his day - a surprisingly amount of what he wrote in that line is actually around online if you hunt for it a bit.

Always surprised JBS hasn't had a full bio before. My theory is that this is because all his personal papers (which he'd taken to India where he worked in his last yrs) were left in a hut after his death and eaten by termites, leaving a biographer w little personal to go on.
