In Search of Schrödinger’s Cat – John Gribbin *****

This has to be one of John Gribbin’s best pure science (as opposed to science/biography) books, and has stood the test of time surprisingly well since being written in 1984. Although some of the implications and developments of quantum theory, notably quantum entanglement, have moved on a lot in more recent years, the basics of quantum theory, which this book covers, still apply, as does the historical context which Gribbin does well here.
The cat in question is the one used by German physicist Erwin Schrödinger as an illustration of just how strange (and unlikely) the whole idea of quantum theory was. Because of the way quantum particles that can be in two states simultaneously until they are observed and randomly become one or the other, Schrödinger envisaged a cat in a box that would live or die dependent on a random quantum event. The suggestion was that, until the box was opened, the cat would be both dead and alive at the same time.
It’s probably the best known image from the quantum world, which is rather a pity, as it was intended to demonstrate the inadequacy of the theory, but in practice misrepresents it at anything more than a trivial level. Though there may be arguments about the workings and interpretation of quantum theory, it stubbornly refuses to be dismissed, matching observed effects with impressive consistency.
Quantum theory isn’t easy to explain in a way that is accessible to any reader, and Gribbin isn’t always the world’s best populariser because he does have a tendency to descend into supposedly helpful examples that can be rather baffling, but this book general avoids that trap remains one of the best attempts at getting across the whole astounding business. Liable to leave your head spinning, but that’s not a bad thing.
It might seem a rather petty complaint, but the Black Swan (UK) paperback reviewed was physically decidely poor – coarse paper and printing (with too little space between the lines of text) – it doesn’t change the content, but does detract something from the reading experience!
Gribbin wrote a sequel, Schrödinger’s Kittens, in 1994 which attempts to bring the picture up-to-date. This is rather less successful, in part as up-to-dateness doesn’t last, and in part because it’s not so well structured. Still some interesting points, though.

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…
