Why Can’t Elephants Jump? – Mick O’ Hare (Ed.) ***

Here we go again with another collection of 114 questions (there’s a title to the next book: Why 114 Questions in these Books?) that first appeared in the ‘Last Word’ section of New Scientist magazine. The format is simple – readers write in with questions, other readers provide answers, the best of which are published. The books contain the question, selected good answers and sometimes editorial comment.
I loved the earlier Why Don’t Penguins’ Feet Freeze?, and still got a lot out of the experiment-oriented How to Fossilize your Hamster. But I did comment in the Hamster review: ‘These books have been great but they aren’t really decent popular science books as they don’t have any narrative flow. The approach has been milked to death now – let’s see something different.’ I unfortunately did get a sense of diminishing returns this time around. Enough, already.
I’m not saying that some of the questions and answers weren’t good. I quite enjoyed, for instance, the title question, which was actually significantly better than the title of the book as ‘Is it true that elephants are the only quadrupeds that cannot jump’. I liked the attempt to work out how long it would take the Earth to freeze if the Sun went out, ‘Is it possible to be too cold to light a fire?’ and ‘Do mosquitoes get malaria?’ But I still had a slight feeling that the barrel was being scraped with many of the items, and increasingly found the replies irritating in their know-it-all way.
Don’t get me wrong, this remains an excellent present for those difficult-to-buy-for people (not for me, thanks, I’ve already got one. And it’s definitely interesting if you haven’t got the previous books (though if you haven’t, I’d go for Penguins’ Feet), but I couldn’t get as excited about this title as the earlier entries in the series.

How to Drive a Nuclear Reactor - Colin Tucker ****

How To Drive A Nuclear Reactor does exactly what it says on the tin. The book is a general overview of nuclear reactors. From the basic principles that make them work through to what buttons to press in what order (and of course how and why they can go wrong).Nuclear power could be a good step on the path to a greener energy future, but there is a lot of understandable fear. This book can give some idea of what an incredible feat of both science and engineering one of these machines is and, hopefully, make anyone reading it feel far more comfortable about them.The book presents information about everything, almost down to the literal nuts and bolts, giving you a near complete understanding of how a nuclear works. From putting in the fuel to getting out the power and down from the control panel to the construction material. Everything you could ever want to know is here. By the end you'll likely feel ready to walk into a control room and get started (do not try doing this, nuclear …

Being Mortal - Atul Gawande ****

I heard recently that the local geriatric ward puts a photograph of the patient in his or her prime by each bed. The aim is to help staff to treat their patients as individuals, but it makes me uneasy. Do these people only matter because of what they were, not what they are? Because once they stood proud and handsome in their uniform, or looked lovely on their wedding day?

Professor Atul Gawande has the problem surgically excised and laid out for inspection in one of his unflinching but compassionate case studies:

‘What bothered Shelley was how little curiosity the staff members seemed to have about what Lou cared about in his life and what he had been forced to forfeit... They might have called the service they provided assisted living, but no-one seemed to think it was their job to actually assist him with living – to figure out how to sustain the connection and joys that most mattered to him.’

Gawande is an eminent surgeon. As a young resident he displayed little overt emotion when hi…

Twenty Worlds - Niall Deacon *****

This is a truly entertaining and informative book, but the reason I’m giving it the full five stars has as much to do with the refreshing novelty of the author’s style as anything else. There’s novelty in the subject-matter too – the wide variety of recently discovered exoplanets orbiting other stars – but even so this is the third book on the topic that I’ve read. The first two were a lot less fun to read, and (without naming and shaming the authors) it’s worth a brief diversion to explain why.The first author was a university professor with a vast knowledge of the subject, who seemed determined to convey the entirety of that knowledge without stopping to think whether it was interesting or necessary for a general audience. The second author – another academic – took a different but equally tedious approach, with a plodding chronological account that focused as much on the dull routine of the scientists involved as on their work.Niall Deacon doesn’t make either of those mistakes. He’…
