Bad Choices - Ali Almossawi ***

At the heart of this little book is a really good concept trying to get out - for me it's what you might call a successful failure. What it's trying to do is great, and being creative about doing so is also great - but creativity goes hand in hand with frequent failure, and I'm afraid there are just too many problems here for me to love this book the way I should.

Let's get the negatives out of the way so we can focus on what's good. It's a very short but expensive book - the 144 small pages have a lot of illustration that conveys very little information. What's left is a text that I comfortably read on an hour-long train ride, yet it's being sold at near £15. The illustrations are genuinely almost all doing nothing at all except adding padding. And though Ali Almossawi's writing style is friendly and laid back, it tends to the condescending. Worst of all, the book doesn't do what it says on the tin.

The subtitle is 'how algorithms can help you think smarter and live happier', implying that this book is going to show you how to make use of algorithms to improve your life. It won't. Almost all the examples it uses (in the form of little stories that try far too hard to be quirky) are totally useless in reality. About the only practically useful one is about sorting books on a shelf (though there is better guidance on that elsewhere - see below). And yet. There is something in this book.

What it really does, if you allow it, is to open up the secrets of what's going on inside a computer - specifically in some of the algorithms used to sort and search, to do lookups with hash tables, to have linked lists that enable you to add items to the middle of an ordered set with a minimum of effort and more. There is definitely a beauty, almost a poetry to this stuff, and Almossawi is usually very good at describing it.

So, it's really not going to do what the cover claims. It won't help you with practical, every day choices and problem solving. If you want a book on practical uses of algorithms in real life, look instead at Algorithms to Live By. And those stories, I'm afraid, for me mostly got in the way rather than made the material more approachable. (Almossawi imagines the reader, when asked 'What's a binary search?' thinking 'Ah, freedom, William Wallace, Eppy Toam*, shirts on a rack.' No, we really won't do that.) But for all that there's a lovely little book on a key aspect of how computers do their jobs lurking in here. I just wish there was more content, and it wasn't so obscured by fluff.

* Yes, his characters really do have names like this.

Four Way Interview - Tom Cabot

Tom Cabot is a London-based book editor and designer with a background in experimental psychology, natural science and graphic design. He founded the London-based packaging company, Ketchup, and has produced and illustrated many books for the British Film Institute, Penguin and the Royal Institute of British Architects. Tom has held a lifelong passion to explain science graphically and inclusively ... ever since being blown away by Ray and Charles Eames’ Powers of Ten at an early age. His first book is Eureka, an infographic guide to science.

Why infographics?
For me infographics provided a way to present heavy-lifting science in an alluring and playful, but ultimately illuminating, way. And I love visualising data and making it as attractive as the ideas are.  The novelty of the presentation hopefully gets the reader to look afresh. I love the idea of luring in readers who might normally be put off by drier, more monotone science – people who left science behind at 16. I wanted the boo…

Einstein's Greatest Mistake - David Bodanis ****

Books on Einstein and his work are not exactly thin on the ground. There's even been more than one book before with a title centring on Einstein's mistake or mistakes. So to make a new title worthwhile it has do something different - and David Bodanis certainly achieves this with Einstein's Greatest Mistake. If I'm honest, the book isn't the greatest on the science or the history - but what it does superbly is tell a story. The question we have to answer is why that justifies considering this to be a good book.
I would compare Einstein's Greatest Mistake with the movie Lincoln -  it is, in effect, a biopic in book form with all the glory and flaws that can bring. Compared with a good biography, a biopic will distort the truth and emphasise parts of the story that aren't significant because they make for a good screen scene. But I would much rather someone watched the movie than never found out anything about Lincoln - and similarly I'd much rather someon…

A Tale of Seven Scientists - Eric Scerri ***

Scientists sometimes tell us we're in a post-philosophy world. For example, Stephen Hawking and Leonard Mlodinow in The Grand Design bluntly say that that philosophy is 'dead' - no longer required, as science can do its job far better. However, other scientists recognise the benefits of philosophy, particularly when it is applied to their own discipline. One such is Eric Scerri, probably the world's greatest expert on the periodic table, who in this challenging book sets out to modify the philosophical models of scientific progress.

I ought to say straight away that A Tale of Seven Scientists sits somewhere on the cusp between popular science and a heavy duty academic title. For reasons that will become clear, I could only give it three stars if rating it as popular science, but it deserves more if we don't worry too much about it being widely accessible.

One minor problem with accessibility is that I've never read a book that took so long to get started. First t…
