We Are Not Alone – Dirk Schulze-Makuch & David Darling ****

I am a little wary of books that make extravagant claims on the cover, then don’t entirely deliver. In this case, the dramatic subtitle is WE HAVE ALREADY FOUND EXTRATERRESTRIAL LIFE. Now, I admit ‘We think we have probably already found extraterrestrial life, though it is just bacterial, so don’t get too excited’ isn’t quite as powerful a tag line, but it would have been closer to the truth.
This doesn’t stop the book itself from being excellent. In the first half there is an in-depth exploration of the findings and uncertainties that have come out of the Mars probes, with a very useful explanation of why what was found is highly suggestive of the possibility of life without being definitive. We get a real sense of the ways that lifeforms could exist in environments that were once thought uninhabitable, plus a truly fascinating set of results that seem so strange there has to be something interesting going on, whether it’s life or not.
The second part is equally interesting, covering Venus and the moons of Jupiter and Saturn – the other possibilities for extraterrestrial life in the solar system. I had heard quite a lot about the moons, but the Venus possibilities (of life existing in the atmosphere, where the temperatures aren’t so blistering) was a new one to me that really tickled the mental facilities.
What really comes across, even though the authors don’t explicitly push this line, is how much we are wasting money on manned missions, when we could be doing much more robotically to explore these amazing worlds. With a suitable investment, rather than the faffing about trying to get people back on the Moon, we would be able to send a lander to Mars that could pick up samples and return them to Earth – the ultimate essential as there is only so much a remote lab can achieve. If ever there was a good rallying cry for shifting funding from manned spaceflight to robotic missions, this is it.
Finished off with a final short section on life beyond the solar system, this is a mostly readable (the writing is just occasionally in need of a bit of a lift) and informative insider view. I would have liked to have been told why the old term xenobiology has been replaced with astrobiology, which sounds much less exciting, but you can’t fault the authors’ knowledge and enthusiasm. I’ll even let them off that dubious claim on the cover. An excellent addition to the genre.

I, Mammal - Liam Drew *****

It's rare that a straightforward biology book (with a fair amount of palaeontology thrown in) really grabs my attention, but this one did. Liam Drew really piles in the surprising facts (often surprising to him too) and draws us a wonderful picture of the various aspects of mammals that make them different from other animals. 

More on this in a moment, but I ought to mention the introduction, as you have to get past it to get to the rest, and it might put you off. I'm not sure why many books have an introduction - they often just get in the way of the writing, and this one seemed to go on for ever. So bear with it before you get to the good stuff, starting with the strange puzzle of why some mammals have external testes.

It seems bizarre to have such an important thing for passing on the genes so precariously posed - and it's not that they have to be, as it's not the case with all mammals. Drew mixes his own attempts to think through this intriguing issue with the histor…

Foolproof - Brian Hayes *****

The last time I enjoyed a popular maths book as much as this one was reading Martin Gardner’s Mathematical Puzzles and Diversions as a teenager. The trouble with a lot of ‘fun’ maths books is that they cover material that mathematicians consider fascinating, such as pairs of primes that are only two apart, which fail to raise much excitement in normal human beings. 

Here, all the articles have something a little more to them. So, even though Brian Hayes may be dealing with something fairly abstruse-sounding like the ratio of the volume of an n-dimensional hypersphere to the smallest hypercube that contains it, the article always has an interesting edge - in this case that although the ‘volume’ of the hypersphere grows up to the fifth dimension it gets smaller and smaller thereafter, becoming an almost undetectable part of the hypercube.

If that doesn’t grab you, many articles in this collection aren’t as abstruse, covering everything from random walks to a strange betting game. What'…

Karl Drinkwater - Four Way Interview

Karl Drinkwater is originally from Manchester, but has lived in Wales half his life. He is a full-time author, edits fiction for other writers and was a professional librarian for over twenty-five years. He has degrees in English, Classics and Information Science. When he isn't writing, he loves exercise, guitars, computer and board games, the natural environment, animals, social justice, cake and zombies - not necessarily in that order. His latest novel is Lost Solace.

Why science fiction?

My favourite books have always been any form of speculative fiction. As a child I began with ghost stories, which were the first books to make me completely forget I was reading. By my teenage years I was obsessed with fantasy, science fiction, and horror. Although I read literary and contemporary books, non-fiction, historical works, classics and so on, it is speculative fiction that I return to when I want escape and wonder. When I read reviews of my last book, the fast-paced novella Harvest Fe…
