The Man from the Future - Ananyo Bhattacharya *****

There are very few individuals who have made such wide contributions to mathematical and scientific topics as did John von Neumann. In this splendid scientific biography, Ananyo Bhattacharya introduces to many for the first time both von Neumann's work and life.

It's easy to get the balance between the life and the science wrong with this kind of biography - Bhattacharya keeps it just right, filling in all the biographical details we need, without falling into the trap of giving us endless boring detail of the von Neumann family's background. Similarly, with a couple of small exceptions I'll mention later, the description of his work is at a level that remains approachable with a bit of effort from the reader, yet we are given enough information to see just how important and novel von Neumann's contribution was.

The significantly more famous Richard Feynman is probably the only twentieth century scientist I can think of with the breadth of interests and originality of von Neumann, though approaching things from the viewpoint of a physicist rather than a mathematician. Feynman was a much better communicator, and probably seemed more approachable to someone who wasn't a world class mind than von Neumann - but it's impossible not to be bowled over by von Neumann's breadth of application.

We start off with his work on set theory in pure mathematics, but where von Neumann really triumphed was in applied mathematics. He starts by making a significant contribution to the development of quantum physics and its mathematical basis. He pretty much devises game theory and makes major contributions to its application in various fields. He is a big player in the Manhattan Project, devising mathematical methods to model nuclear reactions and bomb structures. He is instrumental in the development of electronic computers. And he makes large contributions to the concept of self-replicating automata - devices that can produce copies of themselves and hence, effectively, reproduce like living organisms.

One small issue with the book is that Battacharya gets a bit carried away with the automata, spending far too much time on something that still hasn't achieved anything practical, and telling us far too much about others such as Conway and Wolfram who were inspired by von Neumann, but aren't part of his story. The other negative I'd say is that some of the explanations of the mathematics need a bit more detail to be accessible - as stated it's hard to really get your head around what's being described (and that's even in topics I know a reasonable amount about).

However, these small concerns don't get in the way of this being a very readable and enjoyable scientific biography of someone who, outside those working in related fields such as computer science or game theory, has not had the public awareness that he deserves. It's a great addition to the popular science bookshelf.

Experimenting with Religion - Jonathan Jong *****

The idea of experiments related to religion may seem more than a little odd, but Jonathan Jong's exploration of a small but significant corner of the psychological landscape is genuinely fascinating. The aim is not to somehow prove or disprove religious beliefs, but rather to get a better understanding of what we really believe and what, if anything, influences those beliefs. Since the replication crisis, which has showed that the results of many classic psychology experiments were dubious, I've been suspicious of all claims for new discoveries in the field. What's excellent about the way that Jong approaches it is that he doesn't cover things up (all too often, pop psychology books don't even mention the crisis), but rather openly discusses it. In fact, several of the studies discussed here have proved unreproducible - this is what makes the book particularly interesting. It doesn't just operate at the level of the findings - it tells us how the experiments wer

Quantum Supremacy - Michio Kaku ***

Douglas Adams in The Hitch-Hiker's Guide to the Galaxy points out that the guide starts off frenetically, commenting on how mind-bogglingly big space is, but 'after a while it settles down a bit and it starts telling you things you actually want to know…' Quantum Supremacy is written in this style. To begin with, the reader is battered with all the amazing things quantum computers will (or at least might be able to) do, but eventually things calm down and we get onto some useful content. What you won't find here is any detail on the nature of quantum computers, how they work or on the very significant challenges faced in achieving anything that is to become mainstream. This is all treated at even higher level than a serious newspaper article would. What Michio Kaku is interested in is the potential applications, and the book takes us through a significant number of these. You will read how quantum computers have the potential to transform our understanding of biology

The Future of Geography - Tim Marshall ****

Geography is a strange subject. Parts of it - physical geography - are definitely scientific in nature. The rest - political and social geography is far more removed from anything that could be described as hard science. What Tim Marshall, an expert in foreign affairs, covers here is a strange hybrid - it's all about the political side, but because Marshall is here not considering geopolitics but astropolitics, it has a science and technology aspect. The Future of Geography ( Astropolitics in the US) is about the politics that applies in space, and space inevitably comes with plenty of STEM baggage. The majority of the book is a very effective exploration of how different space-going blocs - notably US, China and Russia, plus significant others like the EU and UK - are likely to take on the potential benefits and risks of space over the next 30 years or so. There is a relatively short consideration of the commercialisation of space (I would have liked a little more on this), but
