Constant Touch – John Agar *****

At first sight it might seem odd that this little book has been awarded our top, 5 star rating. A book about mobile phones? Not much science. Not all that exciting. But John Agar does all the right things. In a simply superb way he weaves together the technology, society, politics and business in a way that works wonderfully – and serves as a strong reminder that science never operates in a vacuum.
In this case, of course, it’s a remarkable technology, not so much from it’s scientific wonder as the speed with which it has become pervasive. Agar argues persuasively that the mobile (cell) phone wasn’t just technologically impossible 50 years ago, but sociologically as well.
He covers the phone’s introduction across the world, why the US lagged behind Europe in second generation phones and how mobile phones have even caused the overthrow of a dictator. Agar conjures up a parallel between the mobile phone and the pocket watch as a portable technology that changes our lives, though there are also strong links made with the automobile industry.
The only glaring omission is that there is no mention of the phone’s capability to act as a portable payment device. About ten years ago, the town of Swindon in the UK was home to a fascinating experiment called Mondex, where plastic cards replaced cash. Although a lot of people never really got the hang of it, those who really got into Mondex found a huge freedom from not having to fiddle around with change, drive to cash machines, and generally handle filthy lucre for transactions too small for a credit or debit card. Mobile phones could provide all of us with instant electronic payment, with the cash coming off your phone credits – but Agar doesn’t seem to have come across this concept.
Don’t let that put you off, though. It’s simply a great little book – as with many of the Icon science books it is very short, but this is an exception where that shortness never comes across as oversimplification.
Excellent.

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...
