Gravity – Brian Clegg ****

Gravity is a subject that sneaks around the senses. It’s all pervasive. It gets everywhere in your life, but on the whole you ignore it, except when it intrudes in the form of a fall. It is, of course, much more than the thing that sticks you to the surface of the planet, as it tends to be presented in children’s non-fiction books. It’s why the Earth stays in orbit. It’s why the Earth and the Sun formed in the first place. And all this from a force that is billions upon billions of times weaker than electromagnetism.

In the same way, gravity tends to be sidelined in popular science books. It creeps into books about relativity, or basic physics. But I’m not aware that it has been treated head on until now. To be honest, when presented with it, I was worried that there wouldn’t be enough material to fill a book, but Brian Clegg has defied that possibility by giving us both a historical journey through humanity’s gradual understanding that gravity existed at all (I love that Newton was criticised because his idea was ‘occult’) up to the amazing breakthrough of general relativity.

This is the most detailed explanation of general relativity I’ve seen in a popular science book, which really helped as most of the ones I’ve seen have left big holes in my understanding. It’s not too technical, though it is the heaviest part of the book and may put one or two people off. It’s followed, though, by the light relief of antigravity, a brilliant subject as it allows all the fringe ideas full rein.

All in all, it won’t appeal so much to the readers of really light weight popular science, but if you like your reading with a bit of meat on it, but without the bafflement of those books from physics professors that stray too far into the maths, this is the one for you.

Review by Peter Spitz

Please note, this title is written by the editor of the Popular Science website. Our review is still an honest opinion – and we could hardly omit the book – but do want to make the connection clear.

Battle of the Big Bang - Niayesh Afshordi and Phil Harper *****

It's popular science Jim, but not as we know it. There have been plenty of popular science books about the big bang and the origins of the universe (including my own Before the Big Bang ) but this is unique. In part this is because it's bang up to date (so to speak), but more so because rather than present the theories in an approachable fashion, the book dives into the (sometimes extremely heated) disputed debates between theoreticians. It's still popular science as there's no maths, but it gives a real insight into the alternative viewpoints and depth of feeling. We begin with a rapid dash through the history of cosmological ideas, passing rapidly through the steady state/big bang debate (though not covering Hoyle's modified steady state that dealt with the 'early universe' issues), then slow down as we get into the various possibilities that would emerge once inflation arrived on the scene (including, of course, the theories that do away with inflation). ...

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...

Ctrl+Alt+Chaos - Joe Tidy ****

Anyone like me with a background in programming is likely to be fascinated (if horrified) by books that present stories of hacking and other destructive work mostly by young males, some of whom have remarkable abilities with code, but use it for unpleasant purposes. I remember reading Clifford Stoll's 1990 book The Cuckoo's Egg about the first ever network worm (the 1988 ARPANet worm, which accidentally did more damage than was intended) - the book is so engraved in my mind I could still remember who the author was decades later. This is very much in the same vein, but brings the story into the true internet age. Joe Tidy gives us real insights into the often-teen hacking gangs, many with members from the US and UK, who have caused online chaos and real harm. These attacks seem to have mostly started as pranks, but have moved into financial extortion and attempts to destroy others' lives through doxing, swatting (sending false messages to the police resulting in a SWAT te...
