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...

Trisha Muro is a lifelong space nerd, former high school physics teacher, and perpetual science communicator who loves helping people see - and appreciate - physics in their lives. She has written for readers of all levels in Science News Explores, OpenMind magazine and NSF NOIRLab. Her new book is It's (Just) Rocket Science : she is donating all proceeds from her book to funding scholarships for kids to attend Space Camp in Huntsville, Alabama. Why science? When I go for a run outside by the lake, I feel the warmth of the sunshine on my skin even while I protect my skin with sunscreen. I try to use good form with my legs, my arm swing, and my feet, in order to maximize the forces propelling me forward while minimizing the impact on my joints. My hips and shoulders shift with each stride as I attempt to keep my balance over uneven ground. I lean forward slightly at the waist to bring my center of gravity further forward, literally leading me onward. Once I’m home, my latte cools ac...

As a particle that has been around the lifetime of the universe and is central to electricity, chemistry and the existence of matter we owe a lot to the electron - but most of us know little about it. Brian Clegg’s biography skims over the first 13.7 or so billion years of its existence to concentrate on the period when humans have been aware of what it does and have gradually come to realise how it acts and what it is. After some mind boggling facts about electrons, the biography starts with lightning - the most noticeable example of electrons at work before we realised they existed. Clegg takes us through fascinating historical steps in our interactions with electricity, from Franklin’s kite and The Electrical Boy to Aldini electrifying a criminal’s corpse in 1803 causing Mr Pass the Beadle to ‘die of fright soon after he returned home’.  In the mid-nineteenth century we see how the electric telegraph enabled The Times newspaper o be on the street in London 40 minutes after the ...
