New Theories of Everything – John D. Barrow ****

Could this be the only science book you will ever need to read? After all it is, in effect, trying to assemble an explanation for life, the universe and everything. Those who worry about unweaving the rainbow will perhaps gain some solace in Barrow’s penultimate sentence in the book. ‘No Theory of everything can ever provide total insight.’ I’ll leave you to read the book to discover the punchline.
This is a brave effort from Barrow to break of all of science down to universals, not in the sense of exploring current thinking in every branch of science, but rather pulling apart the tools that science uses – as he calls it, the eightfold way – and getting a better understanding of the insights that everything from an understanding of symmetry to the nature of universal constants brings us. Along the way, he merrily weaves in an impressive range of associations and concepts that will help in the big picture.
I confess I don’t agree entirely with one of the key axioms that leads to Barrow’s description. He says that … we recognize science to be the search for algorithmic compressions. We list sequences of observed data. We try to formulate algorithms that compactly repesent the information content of those sequences. Then we test the correctness of our hypothetical abbreviations by using them to predict the next terms in the string. These predictions can then be compared with the future direction of the data sequence. Without the development of algorithmic compressions of data, all science would be replaced by mindless stamp collecting – the indiscriminate accumulation of every available fact. While there is plenty of truth in this statement, it seems to miss the real big picture explanatory/sense of wonder aspects of science, limiting it to either stamp collecting (information gathering) or reducing numbers to rules that generate those numbers. It’s no surprise that Barrow is a proponent of the ‘it from bit’ concept that considers the whole universe as, in effect, a vast computer program.
The writing style is probably not for everyone. I was a little unnerved by Barrow’s use of the first person plural (‘it is our intention…’) and in general the feel is something between a university lecture and Radio Four’s ‘In our Time.’ Not a bad thing per se, but at the distancing end of popular science. Even so, this is a powerful book and one that repays the indubitable effort required to read it with some intriguing insights.

The Dialogues - Clifford Johnson ***

The authors of science books are always trying to find new ways to get the message across to their audiences. In Dialogues, Clifford Johnson combines a very modern technique - the graphic novel or comic strip - with an approach that goes back to Ancient Greece - using a dialogue to add life to what might seem a dry message.

We have seen the comic strip approach trying to put across quite detailed science before in Mysteries of the Quantum Universe. As with that book, Dialogues manages to cover a fair amount of actual physics, but I still feel that the medium just wastes vast acres of page to say very little at all. This is brought home here because quite a lot of the sections of Dialogues start with several pages with no text on at all, just setting up the scenario.

As for using a discussion between two people to put a message across, Johnson makes the point that, for instance, Galileo's very readable masterpiece Two New Sciences is in the form of a dialogue (more accurately a discu…

Liam Drew - Four Way Interview

Liam Drew is a writer and former neurobiologist. he has a PhD in sensory biology from University College, London and spent 12 years researching schizophrenia, pain and the birth of new neurons in the adult mammalian brain. His writing has appeared in Nature, New Scientist, Slate and the Guardian. He lives in Kent with his wife and two daughters. His new book is I, Mammal.

Why science?

As hackneyed as it is to say, I think I owe my fascination with science to a great teacher – in my case, Ian West, my A-level biology teacher.  Before sixth form, I had a real passion for the elegance and logic of maths, from which a basic competence at science at school arose.  But I feel like I mainly enjoyed school science in the way a schoolkid enjoys being good at stuff, rather than it being a passion.

Ian was a revelation to me.  He was a stern and divisive character, but I loved the way he taught.  He began every lesson by providing us with a series of observations and fact, then, gradually, between …

A Galaxy of Her Own - Libby Jackson ****

This is an interesting book, even if it probably tries to be too many things to too many people. I wondered from the cover design whether it was a children's book, but the publisher's website (and the back of the book) resolutely refuse to categorise it as such. The back copy doesn't help by saying that it will 'inspire trailblazers and pioneers of all ages.' As I belong to the set 'all ages' I thought I'd give it a go.

Inside are featured the 'stories of fifty inspirational women who have been fundamental to the story of humans in space.' So, in some ways, A Galaxy of Her Own presents the other side of the coin to Angela Saini's excellent Inferior. But, inevitably, given the format, it can hardly provide the same level of discourse.

Despite that 'all ages' comment and the lack of children's book labelling we get a bit of a hint when we get to a bookplate page in the form of a Galaxy Pioneers security pass (with the rather worrying…
