A Brief History of Time – Stephen Hawking *****

The one that started it all – at least the phenomenal interest in popular science books. Hawking’s media presence from Star Trek TNG to BT adverts does nothing to trivialize this remarkable book. It’s one of a very few books in this category that continues to fascinate despite the fact that much of its contents stretch the reader further than is usually expected in a book of this sort.

To be honest, this reviewer avoided the book for many years for two reasons.

The first, which really wasn’t justified, was that this was so much a book that ‘everyone is buying’ that it seemed the cool thing to do to avoid it altogether. If that was your excuse too, it has now had plenty of time to stop being trendy, so you’ve no excuse for not getting it.

The other reason it seemed worth avoiding was its reputation as a book that rivalled Joyce’s Ulysses as one that most people never managed to get through because, trendy though it was, it’s almost impenetrable. If this is your reason for avoiding the book – you (like me) were wrong. It simply isn’t true.
Hawking starts remarkably gently, and though some of the contents are baffling in the small scale, provided you accept the standard undergraduate approach of nodding wisely and continuing whether or not you understand the fine detail, you will find that it fills in nicely with only a few gaps left.

The most baffling bit is probably the section on light cones, which he doesn’t explain very well, and this may well have turned people off before they got further. He goes on to give some really quite approachable summaries of quantum theory, particle physics and the physics of black holes. I just wish he wouldn’t use so many exclamation marks!

I think the difficult reputation itself reflects the way this book started a trend. The fact is, in modern popular science terms, while not an easy read, it’s quite acceptable – in fact just at the right level. If there’s one small doubt it’s the suspicion that the few autobiographical comments, interesting though they are, are thrown in at the instance of an editor saying ‘put something in about yourself, Stephen, that’ll keep them going.’

The fact remains that this book deserves its place on every popular science shelf, not as a trophy or an icon, but as a fascinating, enjoyable read.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life. To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

Humble Pi - Matt Parker ****

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life. I think the book's title is a little weak - 'Humble Pi' doesn't really convey what it's about, but that subtitle 'a comedy of maths errors' is far more informative. With his delightful conversational style, honed in his stand-up maths shows, it feels as if Parker is a friend down the pub, relating the story of some technical disaster driven by maths and computing, or regaling us with a numerical cock-up. These range from the spectacular - wobbling and collapsing bridges, for example - to the small but beautifully formed, such as Excel's rounding errors. Sometimes it's Parker's little asides that are particularly attractive. I loved his rant on why phone numbers aren't numbers at all (would it be meaningful for someone to ask you what half your phone number is?). We discover the trials and tribulations of getting cal...

Quantum 2.0 - Paul Davies ****

Unlike the general theory of relativity or cosmology, quantum physics is an aspect of physics that has had a huge impact on everyday lives, particularly through the deployment of electronics, but also, for example, where superconductivity has led to practical applications. But when Paul Davies is talking about version 2.0, he is specifically describing quantum information, where quantum particles and systems are used in information technology. This obviously includes quantum computers, but Davies also brings in, for example, the potential for quantum AI technology. Quantum computers have been discussed for decades - algorithms had already been written for them as early as the 1990s - but it's only now that they are starting to become usable devices, not at the personal level but in servers. In his usual approachable style, Davies gives us four chapters bringing us up to speed on quantum basics, but then brings in quantum computing. After this we don't get solid quantum informat...
