What If Einstein Was Wrong – Ed. Brian Clegg ***

It’s ironic that the editor of this website, Brian Clegg, has occasionally said he can’t see the point of books with a series of short articles on a subject… only to end up editing just such a book here. I usually review children’s books and this format is very familiar to me – the two page spread, with text on one page and a large illustration on the other – but I do accept it’s more uncommon in adult non-fiction.

For me this particular example works well. If I’m honest, though, the cover made me nervous. With a combination of an ungrammatical title and a picture of E=mc2 crossed out (something that never features inside) it seems as if it may be verging on pseudo-science, but actually the topics (written by a collection of highly respectable authors, including Jim Al-Khalili on the foreword) are the bits of physics that were once or are still challenging and that take people by surprise. In other words, the interesting bits.

The book is divided into seven sections – quantum physics, relativity and time travel, particle physics, cosmology, astrophysics, classical physics and technology. (Ok, that last isn’t really physics, but it’s technology that is physics related.) Each section also has a ‘historical’ entry that was once a little risqué but is now fairly straightforward, like Galilean relativity or the (not) flat Earth. It actually all works surprisingly well. There’s enough text to get a meaty little bit of information, plus a couple of bonus factoids, and some of the illustrations are rather fun.

It’s hard to pick out favourites among the 50 or so topics, but they range from the likes of ‘What if Schrödinger lost his cat?’ to ‘What if Maxwell had a demon?’ You get the feel, I think. Overall entertaining bite-sized physics that would make a good present or just something to read here and there.

Review by Jo Reed

Please note, this title is edited 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.

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...
