The Brain - Gary Wenk ***

There have been plenty of books about the brain, but 'Professor of Psychology and Neurosciences and Molecular Virology, Immunology and Medical Genetics' (I bet he has a big business card) Gary Wenk is, according to the subtitle, out to tell us 'what everyone needs to know' about this important organ. (As the subtitle has a registered trademark symbol, I assume the book is part of a series.)

I found The Brain an easy read in terms of the language (though inevitably we get a string of labels for different parts of the brain), but sometimes I struggled to make sense of what was being said. For example, we're told: 'The brain is the organ of your mind; therefore, food and drugs can have a profound influence on how you think, act and feel.' There seemed to be something missing in the logical argument that allowed that 'therefore' to be used. Further down the same page we read 'Human behaviour has impacted [tobacco and coffee] plants as much as they have impacted human history; for example, the introduction of coffee and tea fuelled the Enlightenment and the Industrial Revolution.' There's a similar logical disconnect. Even allowing for the dubious accuracy of the importance of coffee and tea to the Industrial Revolution, that 'for example' should presage an example of the impact human behaviour has had on the plants, not the other way round. It just doesn't quite make sense - and that happens a number of times.

The book is divided up into short segments, helping the easy reading, though sometimes the titles of these segments have similar issues with the wording. So, for example, there's one headed 'Why are close talkers so frightening?' (each heading is a question), but the text actually describes why some people get too close when they talk, not why they are so frightening. While we're covering writing style, though the book is an easy read, the wording can be very plodding. Take this example:
In order to understand how your brain makes a memory, you first need to learn about brain chemistry and the roles specific chemicals play in the creation of a memory. First, you need to know about a chemical in the brain called acetylcholine.
It's almost as if the text has been proofread, but not edited. An awful lot of it is made up of fact statements, without any narrative flow. However, I shouldn't be too hard on the book. Some sections are genuinely interesting, notably the part on how food and drugs (Wenk points out that there is no meaningful distinction - they're all collections of chemicals) influence the brain.

I end up, then, in a mixed frame of mind (an interesting brain state). I learned a lot and parts of the content were very interesting, but the writing could have been significantly better. You sometimes see a book by an academic that cries out for a co-author, and this is one such. Even so, despite the issues I have with it, it should be of interest if you'd like to take more of a dive into the most complex known structure in the universe.

The Feed (SF) - Nick Clark Windo ****

Ever since The War of the Worlds, the post-apocalyptic disaster novel has been a firm fixture in the Science Fiction universe. What's more, such books are often among the few SF titles that are shown any interest by the literati, probably because many future disaster novels feature very little science. With a few exceptions, though (I'm thinking, for instance, The Chrysalids) they can make for pretty miserable reading unless you enjoy a diet of page after page of literary agonising.

The Feed is a real mixture. Large chunks of it are exactly that - page after page of self-examining misery with an occasional bit of action thrown in. But, there are parts where the writing really comes alive and shows its quality. This happens when we get the references back to pre-disaster, when we discover the Feed, which takes The Circle's premise to a whole new level with a mega-connected society where all human interaction is through directly-wired connections… until the whole thing fails …

Everything You Know About Space Is Wrong - Matt Brown ****

What we have here is a feast of assertions some people make about space that are satisfyingly incorrect, with pithy, entertaining explanations of what the true picture is. Matt Brown admits in his introduction that a lot of these incorrect facts are nitpicking - more on that in a moment - but it doesn't stop them being delightful. I particularly enjoyed the ones about animals in space and about the Moon.

Along the way, we take in space exploration, the Earth's place in space, the Moon, the solar system, the universe and a collection of random oddities, such as the fact that Mozart didn't write Twinkle, Twinkle Little Star. Sometimes the wrongness comes from a frequent misunderstanding. So, for example, Brown corrects the idea that Copernicus was the first to say that the Earth moves around the Sun. Sometimes there's some very careful wording. This is used when Brown challenges the idea that the Russian dog Laika was the first animal in space. What we discover is that, i…

Dark Matter and the Dinosaurs - Lisa Randall ****

I did my PhD in galactic dynamics - which is an awkward subject when people want to know what its relevance to the 'real world' is. So I was excited when Clube and Napier's book The Cosmic Serpent came out, around the same time, because it provided me with a ready-made answer. It argued that the comets which occasionally crash into Earth with disastrous results - such as the extinction of the dinosaurs - are perturbed from their normal orbits by interactions with the large-scale structure of the galaxy.

I was reminded of this idea a few years ago when there was a flurry of media interest in Lisa Randall's "dark matter and the dinosaurs" conjecture. I was sufficiently enthusiastic about it to write an article on the subject for Fortean Times - though my enthusiasm didn't quite extend to purchasing her hardback book at the time. However, now that it's out in paperback I've remedied the situation - and I'm glad I did.

Dark matter is believed to exi…
