Daydreaming in the Solar System - John Moores and Jesse Rogerson ****

It has always seemed that combining fiction and non-fiction should be a good way to put popular science across. After all, SF provides a great vehicle for exploring places where we can't actually go. In practice, though, it seems extremely difficult to successfully pull off the crossover without the result seeming overly contrived. Thankfully, John Moores and Jesse Rogerson make it work well.

It's interesting to make a comparison with Interstellar Tours, which takes a tour of our galaxy on a fictional starship. There, the setting is provided by fiction, but what's experienced around the galaxy is based on best current science. In Daydreaming in the the Solar System we stick to our near neighbourhood: each location from the Moon out to Pluto starts with a short fictional account of 'being there', followed by a chapter on the science behind that scene. This is like a more effective version of the approach attempted with mixed results in the Springer Science and Fiction series, such as Plato's Labyrinth, where a shortish SF novel is followed by a breakdown of the science featured.

The science bits of Daydreaming work effectively to explore what was experienced in the ‘fiction’, in a way that is rather more mathematical than most popular science, though that's not a bad thing. Having said that, I don’t share the authors’ assertion that, having explained what an astronomical unit is 'A fun challenge would be to figure out what the Earth-Moon distance is when expressed in astronomical units instead of kilometres.' If they think that’s fun, they need to get out more.

One thing I didn't like about the generally bland but passable fiction is the use of the second person throughout. It is too specific for this to work in such a setting. A statement like ‘Your first job here on the Moon was at one of those observatories’, which is not about the scene described but a reference to an imaginary past, doesn’t ring true because it gives the reader a back story for which they have no point of reference.

Despite this, I felt that Daydreaming provided an effective way to explore our current understanding of an impressive 15 solar system locations. I enjoyed the book, and anyone with an enthusiasm for space or 'hard' science fiction should do so too.

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 ...
