I Contain Multitudes - Ed Yong ****

Famously, according to Douglas Adams, The Hitchiker's Guide to the Galaxy (not the novel, the 'actual' guide) begin by telling you at length how big space is, but then 'After a while the style settles down a bit and it starts telling you things you actually need to know' - and the opening of Ed Yong's exploration of the microbiome, the complex world of bacterial life inside us and generally in living things and around the world, is rather reminiscent of this. 

In the first couple of chapters, we are fed fact after fact in a staccato collection of information that has no sense of narrative or flow, rather like a set of frenzied bullet points, which becomes wearing for the reader. For example there are two paragraphs in a row, one with practically all the sentences starting 'They', and the next with almost all beginning 'We'll'. Thankfully, though, like the HHGTTG, We Are Multitude then settles down and gets on with job in hand.


It's a job that Ed Yong does very well. It's hardly news that we have many, many bacterial cells in us (though it does biologists no scientific favours when we discover the much used 'ten times as many as human cells' figure was just picked out of the air and has no scientific basis). However, Yong quickly takes us beyond that to explore the nuances of a very intricate relationship between bacteria and more complex life that could be summarised as 'Can't live with them, can't live without them.' Even many of our most hated bacterial foes can have positive roles at the right place and the right time.

What certainly comes across is that our knee-jerk reaction of 'germs are bad' leads to an overemphasis on removing them, where actually they are often doing a useful job. When we go mad with our antibacterial cleansers, we are more like to wipe out good bacteria, leaving space for colonisation by nasties, than we are to simply kill off a threat.  And Yong gives us a dramatic tour of the sheer variety of microbes and the environments in which different bacterial life can thrive, whether we talking black smokers or dolphin armpits.

Every now and then, we get some excellent storytelling, but the use of example after example does give the impression to the non-biologist of the kind of approach that led Rutherford to comment that all science is either physics or stamp collecting - there is a fair amount of stamp collecting here.  However, whenever the reader is beginning to feel that they are losing interest, up comes a really interesting part. I loved, for example, the story of the way that bacteria actually re-engineer the physical structure of a glow-in-the-dark squid. And it's hard not be impressed by the description of bacteria surveys being undertaken in a brand new hospital as it is brought into use, to see where the bugs come from. One of the particularly engaging observations is the emphasis on the benefits of open windows to allow bacteria to come in from the outside. Your mum's enthusiasm for getting you out in the fresh air was justified after all.

If there's one message the reader comes away with, it's that we need to be more nuanced in our thinking about bacteria - sometimes, it seems almost to be a case of 'sit back and enjoy the ride, because whatever you do will probably mess things up.' You'll never look at a probiotic yogurt drink or a bottle of toilet cleaner the same again.

Luna: Moon Rising (SF) - Ian McDonald ****

I'm not the natural audience for this book. Game of Thrones l eaves me cold - and it's hard not to feel the influence of GoT (and a whole lot of Dune )   underneath a veneer of science fiction and the trappings of a South American drug cartel in the cod-medieval family power battles and chivalric details. There are even dragons (of a sort). I'd be really sad if the future did involve this sort of throwback feudalism. However, remarkably, despite this I found Luna: Moon Rising kept me engaged. The fact is that Ian McDonald can put together a good plot with intricate machinations, which is enough to carry the reader through what can be a bewildering collection of characters. The two page scene-setter saying who did what to whom at the start was useful, but I could have done with family trees for the main family as I was constantly forgetting who was who - especially easy as McDonald endows many families with characters with the same first initial (e.g. Ariel and Al...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

E=mc2: A biography of the world’s most famous equation – David Bodanis *****

David Bodanis is a storyteller, and he fulfils this role with flair in E=mc2. The premise of the book is simple – Einstein himself has been biographed (biographised?) to death, but no one has picked out this most famous of equations, dusted it down and told us what it means, where it comes from and what it has delivered. Allegedly, Bodanis was inspired to write the book after hearing see an interview with actress Cameron Diaz in which she commented that she’d really like to know what that famous collection of letters was all about. Although the book had been around for a while already when this review was written (September 2005), it seemed a very apt moment to cover it, as the equation is, as I write, exactly 100 years old. So when better to have a biography? Bodanis starts off by telling us about the individual elements of the equation. What the different letters mean, where the equal sign comes from and so on. This is entertaining, though he seems to tire of the approach on...
