The Logician and the Engineer – Paul J. Nahin ***

For its target readership this is an excellent book – and I have to say as someone outside that market I really enjoyed some parts – but the fact remains it is aimed at a pretty narrow segment. There’s even a little section at the front of the book that effectively says ‘read this to see if you can cope with the rest.’

The bits I found particularly appealing were a few introductory logic problems (though I’m not sure I agreed with all the conclusions) and the pocket biographies of mathematician George Boole and information engineer Claude Shannon. However, while technically qualified to deal with the other parts of the book, in truth I couldn’t be bothered – it was too much like hard work.

For bits of it I would have to wade through far too much grunt maths, and for other bits would have had to think far too hard about electronic circuits and the logic circuits beloved of basement dwellers on computer science courses. (Or was it just my university that confined the computer scientists to the basement?)

I think the author makes the mistake that many academics make when trying to write for a broader audience: they carry through too much of the textbook, and find that the aspects that often encourage people to remember things in that context (often because they involve repetitious grunt work) actually prevent popular science readers from getting the message. It’s a shame, because the subjects are interesting, but unless you are the kind of person who designs logic circuits for fun, this is probably not the book you’d want to see.

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...
