Journey to the Edge of Reason - Stephen Budiansky ***

Compared with the sciences, mathematics can seem relatively short on interesting characters. There's no doubt that the subject of Stephen Budiansky's biography - Kurt Gödel was an engaging subject, from his effective shattering of the certainties of the mathematical system to his increasing oddity in his later life, but perhaps surprisingly this claims to be the first significant biography of Gödel.

Budiansky gives us plenty on the context of Gödel's work and life - and a brief exploration of Gödel's incompleteness theorems (though their nature means that it's hard to give more than a faint impression of how they do what they do). Unfortunately, though, this is not a particularly accessible biography.

With many scientific/mathematical biographies, poor accessibility can be down to a lack of context, with too much focus on the detailed complexities of the science or the maths. Here, though, the issue is the reverse. There is far too much context, so much so that Gödel often gets lost amongst all the detail. After a few introductory pages giving a flash forward to Gödel's death, the first real chapter illustrates this all too well - there is so much material focussing on Austria as it was when Gödel was born that we don’t meet the young Gödel until page 41.

Similarly, later on, the book can feel more like a biography of, say, the disputed genius (or oddball) philosopher Wittgenstein as it is of Gödel. I don't know if it's just that there isn't too much biographical detail on Gödel himself (which would explain why it has taken so long to get a biography), or if Budiansky simply enjoys going off on tangents, but I found it hard not to keep skipping forward to find the next mention of the purported subject of the book.

A bit of a frustrating experience, then. There is no doubt that there is plenty of interesting material here, but far too much history, philosophical context and detail on obscure academics that Gödel interacted with, and not enough on the man himself.

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...
