On Gravity - A Zee ***

This is the first book I've read where I had to force myself to stop thinking about the author's name - and specifically from asking myself if his middle name is 'To' (I bet he hasn't heard that one before) - to be able to concentrate on the subject. It's the second book I've read on gravity and gravitational waves in the last few weeks, and it didn't work for me as well as the Pierre Binétruy title Gravity! In part it's down to A Zee's writing style, which is extremely mannered (not to mention constantly referring to his other books), but the content also simply didn't put the information across very well.

Things start in a promising way (despite the style). The first lines of the prologue give a suitable feel: 'Finally, finally, the long wait was over: we the human race on planet earth collective heard the song of the universe. Yes, we, a rather malevolent but somewhat clever species, can now proudly say we have detected the ripples of spacetime...' (i.e. gravitational waves). Sometimes the wording is a little odd, and the tone can be irritatingly breezy, but what we get to begin with is exactly what we are promised - an introduction to gravity that is not too technical, but above the trivial level. Admittedly, the use of end notes for what should be footnotes - usefully expanding on a point rather than providing reference information - is irritating as you either painfully flick back and forth or (more likely) simply miss some of the best content, but things are going quite well.

However, a couple of chapters in, Zee falls for the classic error of a scientist writing for the general public (especially common when they're writing for a university press). Probably without even noticing that he's done it, he changes gear and suddenly we've gone from popular science to the level of accessibility of an introductory textbook (though still with the same odd tone). This means that much of the material on electromagnetism, relativity and more becomes increasingly impenetrable as you read on.

What is particularly sad is that the transition happens before Zee gets on to the principle of least time/action (and action in general). He covers this at considerable length (pointing out, for example, that it makes Einstein's field equations for general relativity in some ways a simpler concept) and that is brilliant. This is by far the most interesting and original part of the book as far as a general audience goes, because it's something that is usually only touched on (often in reference to Richard Feynman), but unfortunately it is virtually incomprehensible in the way it's put across.

Overall, then, a strange book that seems sadly to be poorly matched to its audience.

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

The New Lunar Society - David Mindell *****

David Mindell's take on learning lessons for the present from the eighteenth century Lunar Society could easily have been a dull academic tome, but instead it was a delight to read. Mindell splits the book into a series of short essay-like chapters which includes details of the characters involved in and impact of the Lunar Society, which effectively kick-started the Industrial Revolution, interwoven with an analysis of the decline of industry in modern twentieth and twenty-first century America, plus the potential for taking a Lunar Society approach to revitalise industry for the future. We see how a group of men (they were all men back then) based in the English Midlands (though with a strong Scottish contingent) brought together science, engineering and artisan skills in a way that made the Industrial Revolution and its (eventual) impact on improving the lot of the masses possible. Interlaced with this, Mindell shows us how 'industrial' has become something of a dirty wo...
