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 ...

Reading Victorian fiction can be difficult without context - in some cases, an annotated version can work wonders. The best remains Martin Gardner's wonderful annotation of the Alice books and The Hunting of the Snark , but while the annotation of Jules Verne's moonshot tale lacks Gardner's light touch it still delivers plenty of useful background. I started devouring science fiction when I was around 11 and worked my way through both Verne and H. G. Wells alongside more contemporary books. I found Verne stodgy and slow compared with the dramatic power of War of the Worlds or the humour of The First Men in the Moon , but it was still interesting, and Walter James Miller's 1995 translation works better than the version I came across way back then. What I doubt pre-teen me picked up was the way Verne pokes fun at America where the book is set, though even then I was doubtful about the concept of sending men to the Moon in a projectile from a huge cannon. Surely, I though...

Geoffrey Cain is an award-winning author and correspondent who sits  down with world leaders, tech founders, and dissidents. His book  Samsung Rising was longlisted for the Financial Times and McKinsey  Business Book of the Year, and The Perfect Police State was named  NPR's Book of the Day. His work has appeared in The Wall Street  Journal, Time, The Economist, and Wired and has been featured on CNN  and Bloomberg TV. He also advises executives and government officials  on innovation. His latest book is Steve Jobs in Exile . Why this book? For years I covered Apple, Samsung, Sony, and the rest, and the people who knew Steve kept telling me the same story. They said his middle chapter at NeXT was missing -- few people were really looking into it. Everyone knows the young founder and everyone knows about his triumphant return, when he saved Apple from bankruptcy. But during the part in between, he wasn't wandering aimlessly - he was in his crucible, t...

If there was an A to Z of SF greats, while even younger science fiction readers could probably come up with A for Asimov, far fewer are likely to make Z for Zelazny - which is a shame. Unusually, Zelazny spanned science fiction and fantasy - although a touch pulpy, his Princes in Amber series of books were a genuinely different fantasy series - but he was also, without doubt one of the leading SF writers of the twentieth century. Here we get collected what should be some of his greatest short stories and novellas, starting with the classic and poignant A Rose for Ecclesiastes. For some reason in the intro we are told about a story that's not included that should be - 24 Views of Mount Fuji by Hokusai - why isn't it here, then? In some ways, the experience of reading the book was a disappointment, because I think I prefer the lowbrow version of Zelazny's writing in those Amber books, rather than his new wave, more intellectual work, which mostly features here. I did enjoy...

There have been some excellent books on the origins of life, notably Philip Ball's How Life Works and Henry Gee's A Very Short History of Life on Earth , taking distinctive approaches. The field might feel overcrowded - except Christophe Galfard managed to come along with a whole new, highly entertaining take on the project with a physicist's-eye-view. We begin with evolution. An excellent example of Galfard's sideways take on the topic is the short chapter entitled 'Why alien fish don't fly'. This starts with the reader picturing themselves lying by a river in a forest clearing. A fish jumps out of the river... but doesn't swim towards the clouds, it drops back in. We then pivot to Aristotle dividing the universe into the bit with the Earth and the bit outside the Moon's orbit - and giving us the concept of natural laws (including that a jumping fish will drop back). Then Newton breaks Aristotle's barrier between Earthly things and the heavens,...

This is an odd one. Ignore the title that sounds like it describes what goes on in a household repair shop - Gwen Ottinger makes an important point about the way that the attempt to use science to support social justice - such as when a community is blighted by pollution from an oil well - can be both positive and negative. While it's true that science can be used to identify pollutants and risks, scientists' natural tendency to caution may make a risk seem less significant than it is - and there is a danger that only the science viewpoint prevails, where the experience of those living in bad conditions is important too. All too often, scientists can dismiss local knowledge.  My old literary agent's first question when approached with a book idea was always 'is it a book or a magazine article?' I think this would be well applied here. Ottinger's point could have been well-made in a feature-length article, but there was an awful lot of repetition required to stre...
