Ananyo Bhattacharya - Five Way Interview

Ananyo Bhattacharya holds a PhD in biophysics from Imperial College London and a degree in physics from Oxford University. He has worked as a science correspondent at the Economist, an editor at Nature, and a medical researcher at the Sanford Burnham Prebys Medical Discovery Institute in San Diego, California. He lives in London. The Man from the Future is his first book.

Why maths?

I remember my maths teacher in school many years ago being asked by a bored student what the point of maths was. A look of blind panic crossed his face then, after a good deal of hemming and hawing, he mumbled something about checking your till receipt after shopping in a supermarket. Popular maths books are often about fun puzzles or perhaps one person's passionate, otherworldy pursuit of some arcane theorem. I wanted to try something different. My book was an effort to show that maths isn't really about sums or shopping bills. It has shaped the modern world and informs the way we think about everything from nuclear strategy to our own happiness. 

Why this book?

If you want to show how maths has changed our lives, there are few better ways to start than with John von Neumann. He's much less well known than Einstein or even Turing but his impact on our lives is much greater than either. Over the past twenty years or so in journalism, I kept hearing his name more and more often in an astonishing variety of different contexts. This struck me as odd. Von Neumann died from cancer over sixty years ago, aged just 53. So though his name’s faded away from public consciousness, his legacy seemed more important than ever. So what better subject for a book?

Which of von Neumann’s contributions would you say was most significant?

Every computer you’re likely to use from smartphone to desktop runs on the von Neumann architecture. And because von Neumann insisted much of work on building his computer should be in the public domain, he could be considered the father of the open source movement. So I’d have to say his most significant work was in catalysing the information age.

But I think in another couple of decades we might look at his theory of reproducing automata and his extraordinary mathematical proof that machines could reproduce and say that was actually his most influential work, as by then I suspect that either through synthetic biology or nanotechnology we'll have programmable factories that can make copies of themselves.

What’s next?

I'm in the middle of a science fiction novel for kids, which I hope to finish in the next few months. Anyone that's read The Man from the Future or knows something about von Neumann will recognise a few of his ideas in there, assuming it's published!

What’s exciting you at the moment?

The Man from the Future was really a biography of von Neumann's ideas rather than the man. What I'd like to do with my next non-fiction book is to trace a big idea over time, following its evolution through art, philosophy and literature as well as mathematics and physics. That may prove too ambitious but if so, at least it'll be fun failing.

Beyond Belief - Helen Pearson *****

Apparently it comes as a surprise to many that medicine was not particularly scientific until the end of the twentieth century (to be honest, it's no surprise to me - we had a GP who used homeopathy in the 90s). Instead it was based on anecdotal guidance - the kind of thing that appeared to work. Evidence-based medicine has since improved the field, trying where possible to base decisions on evidence, ideally based on randomised controlled trials. The first part of Helen Pearson's book covers this well - though I think it's by far the least interesting part of what we discover. Instead what's truly fascinating is the rest of it, looking at a wide range of other fields where evidence was rarely properly used and that are only now starting to dip a toe in the water. These include social policy, policing, conservation, business and education. The main part of the book gives us examples of how bad these areas have been in terms of basing decisions on what's always been ...

The Infinite Book – John D. Barrow ****

Authors are often asked to review books on a topic they’ve written on themselves. The reasoning is sensible – they ought to know something about the subject – but there’s always that uneasy suspicion that there’s going to be a bit of bias creeping in. So I think it’s only fair to admit up front that I have written a book on infinity (of which more later). Infinity is a wonderful subject, because it’s intimately mind-bending (if the combination sounds paradoxical, that’s what infinity is all about) and gives you the chance to pull in all sorts of different concepts and assocations along the way, something Barrow does with great gusto. There’s a surprisingly large amount of coverage here for God, and for the universe, and the book jumps around from Aristotle to Hilbert’s Infinite Hotel (explained at great length), from the paradoxes of infinite sets to the paradoxes of time travel. Overall it’s an enjoyable journey that gives plenty of opportunity to be amazed and surprised. The...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...
