Inventing Reality – Bruce Gregory *****

I am decidedly in awe of this book. It is simply the best, straightforward description of physics I have ever read.
I do have to get one proviso in straight away. This isn’t a typical popular science book. Although it is accessible and hasn’t got formulae, it is a rather cold, clinical, dry assessment with little of the storytelling and use of biographical detail that makes popular science more approachable. It is, arguably, a very readable textbook, rather than a popular science book. But if you are prepared to put in the effort to read it, it builds the structure of classical and then modern physics layer by layer in a way that makes it all beautifully clear.
But that’s not the most remarkable thing – because in a way explaining physics is only a sideline of the book. Its main theme is the way that science, and physics in particularly, is a construct, a way of predicting what happens that is quite detached from whatever reality may be. It shows why, for instance, Feynman’s instance that everything quantum was particles, and the more prevalent idea among modern physicists that everything is fields is not a disagreement but simply two descriptions both of which work to match what is observed and neither of which is any more than a model of reality. The subtitle is ‘physics as language’ for a reason.
So don’t expect fun stories, and do expect to work quite hard to take in a combination of practically everything important aspect of physics and some quite heavy duty philosophy all in a single slim tome. But it is so worth the effort. You will both understand the nature of physics better and see science in a whole new light. It is quite possibly the best book about science I have ever read.
This is not a new book – it came out in 1988 and depressingly it is out of print, though you can get copies from Amazon Marketplace (if you don’t mind a used copy, very cheaply).  But apart from technological references (for instance it thinks the collider that might find the Higgs is the never-built American SSC, not the LHC) there is nothing whatsoever that has dated here.
There is something of a tendency to bring back out of print books as ebooks as it’s cheap to do – please Wiley, do it for this one. The world needs it.

The Art of Statistics - David Spiegelhalter *****

Statistics have a huge impact on us - we are bombarded with them in the news, they are essential to medical trials, fundamental science, some court cases and far more. Yet statistics is also a subject than many struggle to deal with (especially when the coupled subject of probability rears its head). Most of us just aren't equipped to understand what we're being told, or to question it when the statistics are dodgy. What David Spiegelhalter does here is provide a very thorough introductory grounding in statistics without making use of mathematical formulae*. And it's remarkable.

What will probably surprise some who have some training in statistics, particularly if (like mine) it's on the old side, is that probability doesn't come into the book until page 205. Spiegelhalter argues that as probability is the hardest aspect for us to get an intuitive feel for, this makes a lot of sense - and I think he's right. That doesn't mean that he doesn't cover all …

The Best of R. A. Lafferty (SF) – R. A. Lafferty ****

Throughout my high school years (1973–76) I carefully kept a list of all the science fiction I read. I’ve just dug it out, and it contains no fewer than 1,291 entries – almost all short stories I found in various SF magazines and multi-author anthologies. Right on the first page, the sixth item is ‘Thus We Frustrate Charlemagne’ by R. A. Lafferty, and his name appears another 32 times before the end of the list. This isn’t a peculiarity of my own tastes. Short stories were much more popular in those days than they are today, and any serious SF fan would have encountered Lafferty – a prolific writer of short fiction – in the same places I did.

But times change, and this Gollancz Masterworks volume has a quote from the Guardian on the back describing Lafferty as ‘the most important science fiction writer you’ve never heard of’. Hopefully this newly assembled collection will go some way to remedying that situation. It contains 22 short stories, mostly dating from the 1960s and 70s, each w…

David Beerling - Four Way Interview

David Beerling is the Sorby Professor of Natural Sciences, and Director of the Leverhulme Centre for Climate Change Mitigation at the University of Sheffield. His book The Emerald Planet (OUP, 2007) formed the basis of a major 3-part BBC TV series ‘How to Grow a Planet’. His latest title is Making Eden.

Why science?

I come from a non-academic background. None of my family, past or present, went to university, which may explain the following. In the final year of my degree in biological sciences at the University of Wales, Cardiff (around 1986), we all participated in a field course in mid-Wales, and I experienced an epiphany. I was undertaking a small research project on the population dynamics of bullheads (Cotus gobio), a common small freshwater fish, with a charismatic distinguished professor, and Fellow of the Royal Society in London. Under his guidance, I discovered the process of learning how nature works through the application of the scientific method. It was the most exciting t…
