Andrew Jaffe is professor of astrophysics and cosmology at Imperial College, London and director of the Imperial Centre for Inference and Cosmology. His new book is The Random Universe. Why science? I’ve always been interested in science, in particular in  astronomy, astrophysics, and space. One of my earliest memories - back in nursery school in New Jersey, I think - was watching one of the moon launches. I wanted that excitement to be part of my life! I never got to be an astronaut, but I did get to be part of the Planck Satellite team, and was privileged to be able to travel to the ESA Spaceport in French Guiana to watch the launch.  In between, I was lucky enough to have a supportive family, get a good education, and find inspiring teachers, mentors, and collaborators. They helped me model the universe, and helped me learn how to refine those models in the face of experimental and observational evidence. That is, they taught me to be a scientist. Why this book? The Random...

The central thesis presented by Roopika Risam is that information gives us (and particularly countries) the power to organise, control and dominate others. Although I have a couple of issues with the presentation, this is a genuinely interesting trip through the history of our use of stored information from the earliest tallies to the latest information technology. I loved a quote from Lisa Gitelman that data is is always 'cooked' so 'raw data is an oxymoron'. This neatly underlines Risam's thesis that data and information are not neutral facts, but rather tools that (like everything from fire to electronics) can be used for good or evil. As we are taken through the historical context, it can sometimes be a little difficult to judge whether Risam regards a particular example as bad or good, even when the outcome is disastrous. One thing I didn't like too much is the adherence to a popular science writing approach that has got distinctly hackneyed: opening chapte...

Christophe Galfard holds a Ph.D. in theoretical physics from the University of Cambridge, where he was Stephen Hawking's graduate student from 2000 to 2006, researching the so-called black hole information paradox. With Stephen Hawking and his daughter Lucy Hawking, he co-authored George’s Secret Key to the Universe. His own book, The Universe in Your Hand, has been translated into over twenty languages. His new book is This is Life . Why science? Because as far as I am concerned, it is by far, the most powerful, imaginative and thrilling discipline ever invented by mankind, a discipline whose discoveries are humankind’s common heritage. Why this book? I wrote this book so that everyone can have an up to date knowledge of what is known about life here on Earth - from its beginning to the most recent medical discoveries - and out there in outer space. I love the way you link from one topic to another, often in rapid succession: was this a conscious decision, or does it reflect your ...

I love popular science books, but it's a quiet sort of love: it's not often a book like this gets me really excited - but Meet the Neighbours (sorry, I know it's Neighbors, but it grates) does just that.  Once upon a time there was quite a market in books speculating about life on Mars, but of late most Martian titles have focused on getting to and colonising Mars (though often avoiding the 'c' word). Steven Benner drags us back to see the evidence for life having existed there, and does so with a vengeance. (Almost literally - he really lays into those who are dismissive of what evidence there is.) Do we have proof? Well, no - but proofs are for mathematicians. As Benner says 'science does not deal in proof... Rather, it relies on a 'preponderance of evidence' standard to shift the burden of proof.' Benner points out the weird reality that since the Viking landers, which arrived in the 1970s, there hasn't been a mission looking for organic sig...

Remarkably for those who came across it in the early days, this classic of popular science writing is now 50 years old - and like many of us who reach a certain age it has become somewhat overweight: a reasonable sized paperback has morphed into a 500-page monster. Even so, we have to recognise the importance of the book, despite its message not being as clear as it once was. One major change is that Dawkins, with his God Delusion hat on, was once the hero of the provisional wing of the progressive movement, where now he has been pushed aside for daring to suggest that there are only two sexes. The other change, of course, is that the science has moved on and some of the genetics certainties of Dawkins' day have reached the scientific stage of 'it's more complicated than we thought.' In a couple of chapters that weren't in the original book and about 120 pages of discursive end notes and an epilogue, Dawkins attempts to clarify some scientific developments and to ...

The introductory chapter of this book, called 'there is something about chips' encourages a response of 'especially with salt and vinegar', but the reality we are presented with in this analysis of the importance of computer chips to technology and the world economy is more reminiscent of another edible delight: the banana. Bananas are hugely popular, but the world supply is fragile because it is largely dependent on a monoculture. A single cultivar, the Cavendish, makes up over 99 per cent of exports to developed countries. These bananas have very little genetic diversity as they are propogated by cloning. This leaves them open to devastating attack, most likely by a fungal disease, which could wipe out the worldwide supply. Similarly, when it comes to IT, more than 90 per cent of advanced chips are made by a single company, TMSC, based in Taiwan. Not only does this concentration put supply at risk, Taiwan's difficult political position, with the danger of being su...
