Andrew May - Four Way Interview

Andrew May obtained his PhD in astrophysics from the University of Manchester in 1982. After a 30-year career spanning academia, the civil service and private industry he now works as a freelance writer and science consultant. He has written on subjects as diverse as the physical sciences, military technology, British history and the paranormal. His recent books include pocket-sized biographies of Newton and Einstein and an eye-opening study of the relationship between pseudoscience and science fiction. He lives in Somerset and his latest title is Destination Mars.

Why science?

I hate getting into arguments. If you write about art or literature or history or politics, then it's all a matter of opinion and some people are going to disagree strongly with anything you say. You're never going to see eye to eye with them, so you wind up in endless, fruitless arguments. Of course you can have disagreements about science, too - you can make mistakes, or readers might get the wrong end of the stick. But ultimately there's a real, objective truth underlying most science topics - it's not just personal opinion - and that's the great attraction for me.

Why this book?

The focus of this new series from Icon Books, Hot Science, is on 'trending' science topics - things that everyone's heard about from the news headlines, but perhaps don't understand in any depth because it's not the sort of science that's taught in school. That whole concept appeals to me - and my particular contribution, Destination Mars, happens to be one specific area that I'm reasonably well qualified to write about.

What's next?

After Mars - the Moon! That may sound like a backward step, but for anyone who's invested in a small telescope, Mars will have been a terrible disappointment. You can't have much fun looking at a tiny, featureless orange dot. The Moon is completely different - you can spend hours exploring the seas and craters and mountains, seeing where various manned and unmanned spacecraft landed, where classic science fiction novels were set, and where astronomers in the past thought they spotted evidence of life and other anomalies. That's the idea behind my next book - The Telescopic Tourist's Guide to the Moon, to be published by Springer later this year.

What's exciting you at the moment?

As far as human spaceflight is concerned, I'm much more excited by the things private companies - SpaceX in particular - are getting up to than anything NASA is planning these days. Unlike many people, though, I find unmanned space exploration exciting too - and that's where NASA comes into its own. Not just Mars, but the moons of Jupiter and Saturn as well. Places like Europa and Titan are as exciting as science gets - I wouldn't put money on life NOT being found there in the not-too-distant future!

The Antigravity Enigma - Andrew May ****

Antigravity - the ability to overcome the pull of gravity - has been a fantasy for thousands of years and subject to more scientific (if impractical) fictional representation since H. G. Wells came up with cavorite in The First Men in the Moon . But is it plausible scientifically? Andrew May does a good job of pulling together three ways of looking at our love affair with antigravity (and the related concept of cancelling inertia) - in science fiction, in physics and in pseudoscience and crankery. As May points out, science fiction is an important starting point as the concept was deployed there well before we had a good enough understanding of gravity to make any sensible scientific stabs at the idea (even though, for instance, Michael Faraday did unsuccessfully experiment with a possible interaction between gravity and electromagnetism). We then get onto the science itself, noting the potential impact on any ideas of antigravity that come from the move from a Newtonian view of a...

The World as We Know It - Peter Dear ***

History professor Peter Dear gives us a detailed and reasoned coverage of the development of science as a concept from its origins as natural philosophy, covering the years from the eighteenth to the twentieth century. inclusive If that sounds a little dry, frankly, it is. But if you don't mind a very academic approach, it is certainly interesting. Obviously a major theme running through is the move from largely gentleman natural philosophers (with both implications of that word 'gentleman') to professional academic scientists. What started with clubs for relatively well off men with an interest, when universities did not stray far beyond what was included in mathematics (astronomy, for instance), would become a very different beast. The main scientific subjects that Dear covers are physics and biology - we get, for instance, a lot on the gradual move away from a purely mechanical views of physics - the reason Newton's 'action at a distance' gravity caused such ...

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...
