Significant Figures - Ian Stewart ****

Ian Stewart's books can be excellent, but sometimes he forgets that much maths that excites mathematicians produces from the mere mortal a response of 'So what?' When he's on form, though, he's very good - and in this book he definitely hits the spot.

Inevitably with a book like this, giving short summaries of the lives and works of leading mathematicians, it's easy to question the gaps. Where are John Wallis and assorted Bernoullis, for example? And there is one entry, frankly that seems bizarre. I can see no reason whatsoever for Ada King to be here (though I appreciate his use of her surname, rather than using her title). Whatever Stewart's thinking, there is absolutely nothing in this entry to suggest that King was in any sense a 'trailblazing mathematician' (as the subtitle puts it).

However, I really enjoyed the range of mathematicians covered, with a good mix of familiar figures (Archimedes and Newton, for example) to those I'm ashamed to say I've never heard of, or knew the name and very little else (Nikolai Lobachevsky springs to mind). As much as possible, Stewart describes their mathematical achievements in an approachable way, though sometimes his explanations get fairly dense, or he does use a term that isn't in common usage without explaining it.

Perhaps not surprisingly, the coverage of the maths is sometimes better than the historical content. While I loved the dramatic nature of the Cardano entry (it made me think I need to look out this sixteenth century mathematician's autobiography) we got, for instance, a very vanilla version of Newton's biography - sustaining the now generally doubted idea that Newton did much of his work in the 2 years that Cambridge was suspended due to plague and pointing out that Newton was only the second ever scientist to be knighted, but not that neither he nor Francis Bacon were knighted because of anything to do with science (assuming you can call Bacon a scientist).

There is no doubt that mathematicians tend to be less familiar as people than are scientists. Even if you've used Fourier analysis, say, you may well have little idea of who Fourier was and how the technique came about. Stewart has done a real service here. I think, perhaps, the ideal audience would be scientists who use these mathematicians' work without being aware of the person behind it, but as long as the reader has a degree of tolerance for mathematical terminology and exposition (if you get the pun in the title, you should be fine), it ought to prove an appealing read.

Ignorance: How it drives science – Stuart Firestein *****

This is a delightful little book that really gets you thinking. I stress the ‘little’ part not as a negative, but as a good thing. There is nothing worse than fat, bloated popular science books where the author feels they have to get 120,000 words to be taken seriously. This is the sort of book that can be read in a couple of hours – but you will get so much more out of it than one of those tedious doorstops. The premise underlying the book is in once sense extremely simple, yet is fundamental to an understanding of what science is and what scientists do. And it is an understanding that is totally at odds with the typical way science is portrayed both in university lectures and popular science books. As Stuart Firestein points out, what is important is not the facts, but rather the area of ignorance. The interesting part and the fundamental heart of science is not about what we know, but about what we don’t know and where we want to look next. Take this lovely quote: ‘Working ...

Who Invented the Computer? – Ian Watson

Ian Watson is the author of  The Universal Machine  and featured in a recent  Four Way Interview . Saturday June 23 2012 was the centenary of the birth of Alan Turing, the troubled genius who invented the modern computer. Why though do so few people recognize his name and his great achievements? In 1936 English mathematician Alan Turing, published a paper,  On Computable Numbers, with an application to the Entscheidungsproblem . This became the foundation of computing. In it Turing presented a theoretical machine that could solve any problem that could be described by instructions encoded on a paper tape. A Turing Machine could calculate square roots, whilst another might solve Sudoku puzzles. Turing demonstrated you could construct a single  Universal Machine  that could simulate any Turing Machine. One machine solving any problem for which a program could be written – sound familiar? He’d invented the computer. Then,  computers  were peop...

The Star Book – Peter Grego ****

This attractive landscape format book combines an excellent introduction to the stars and basic astronomy with a set of star maps, plus in depth looks at some of the stars featured, with a  bonus section on the solar system. Amazon says it’s a hardback, but in fact it’s a paperback with a rather ingenious cover – you can’t tell from the photo, but the words ‘The Star Book’ are punched through as a series of holes that show the white paper of the next page beneath. Like many astronomy/space books, the cover lacks shelf appeal because it is mostly black, but at least there is some original thought here. Unlike many books in this format which tend to concentrate on the pictures, there is a good deal of excellent text by Peter Grego, so there was no feeling that you were only getting the star maps and star ‘biographies’, something these days much more suited to an iPad or smartphone app. Instead, the opening 30 or so pages give a very good introduction that would be valuable to ...
