The Science of Food - Marty Jopson ****

This is a tasty little volume, packed with kitchen-based science. I must admit, when I saw that the author was the One Show's science expert and Marty Jopson's author photo has that 'Hey, I'm a mad scientist, kids!' look, my heart fell - I was sure the book would be the written equivalent of a 'Wow, look, aren't I clever, I can make this go bang!' science show - but, in fact, it's packed full of (appropriately) meaty scientific content.

I was really pleased that Jopson didn't stick purely to the chemistry of cooking, but launched with the working of some familiar kitchen gadgets - there was genuinely fascinating reading to be had about apparently humdrum equipment in the form of the physics and materials science of a knife and chopping board. And Jopson took us into industrial kitchens too, to reveal, for example, the remarkable process required to make puffed wheat.

Inevitably, the chemistry of cooking - how, for example, proteins denature and emulsions like mayonnaise work - are well covered too. Though interesting, this is probably the least inspiring part of the book, as it involves covering similar ground on how long chain molecules react to heat, water or each other several times.

There's plenty more, though, despite this being the kind of book you can read on a reasonable length train journey. Again, for example, going against the 'TV scientists are superficial' grain, Jopson gives a really well balanced view on artificial sweeteners and the implications of the many studies using them. He points out, for example, that the studies sometimes quoted showing those using sweeteners don't lose weight because they eat more to compensate is from rat experiments - the studies based on people are inconclusive. 

Later, we've got the science of taste, from chocolate to sprouts, and so it goes on. Food is certainly the linking factor, but by no means all of the book is just about food, and that's a real strength. One of the last sections looks at some aspects of using science to improve crops - here's the only part it seemed there was an obvious omission, as it would have been a good point to re-examine the GM foods debate.

All in all this is a delightful cheese soufflé of a book. Light and tasty but enough content to satisfy the appetite for information.

The Feed (SF) - Nick Clark Windo ****

Ever since The War of the Worlds, the post-apocalyptic disaster novel has been a firm fixture in the Science Fiction universe. What's more, such books are often among the few SF titles that are shown any interest by the literati, probably because many future disaster novels feature very little science. With a few exceptions, though (I'm thinking, for instance, The Chrysalids) they can make for pretty miserable reading unless you enjoy a diet of page after page of literary agonising.

The Feed is a real mixture. Large chunks of it are exactly that - page after page of self-examining misery with an occasional bit of action thrown in. But, there are parts where the writing really comes alive and shows its quality. This happens when we get the references back to pre-disaster, when we discover the Feed, which takes The Circle's premise to a whole new level with a mega-connected society where all human interaction is through directly-wired connections… until the whole thing fails …

The Bastard Legion (SF) - Gavin Smith *****

Science fiction has a long tradition of 'military in space' themes - and usually these books are uninspiring at best and verging on fascist at worst. From a serious SF viewpoint, it seemed that Joe Haldeman's magnificent The Forever War made the likes of Starship Troopers a mocked thing of the past, but sadly Hollywood seems to have rebooted the concept and we now see a lot of military SF on the shelves.

The bad news is that The Bastard Legion could not be classified as anything else - but the good news is that, just as Buffy the Vampire Slayer subverted the vampire genre, The Bastard Legion has so many twists on a straightforward 'marines in space' title that it does a brilliant job of subversion too.

The basic scenario is instantly different. Miska is heading up a mercenary legion, except they're all hardened criminals on a stolen prison ship, taking part because she has stolen the ship and fitted them all with explosive collars. Oh, and helping her train her &…

The Laser Inventor - Theodore Maiman ****

While the memoirs of many scientists are probably best kept for family consumption, there are some breakthroughs where the story is sufficiently engaging that it can be fascinating to get an inside view on what really happened. Although Theodore Maiman's autobiographical book is not a slick, journalist-polished account, it is very effective at highlighting two significant narratives - how Maiman was able to construct the first ever laser, despite having far fewer resources than many of his competitors, and how 'establishment' academic physicists, particularly in the US, tried to minimise his achievement.

On the straight autobiographical side, we get some early background and discover how Maiman combined degrees in electrical engineering and physics to have an unusually strong mix of the practical and the theoretical. Rather than go into academia after his doctorate, he went into industry - which seems to have been responsible for the backlash against his invention, which we…
