Three films on fractal geometryThis recently released DVD contains three films on fractal geometry, all directed and produced for a general audience by Nigel Lesmoir-Gordon.

'The mathematician's brain' I will tell you all about the book, but first I want to tell you what it felt like to read it. It felt like being back at the beginning of my adventure into mathematics. It felt like the first time the history, culture, and philosophy of maths were unfolded before me.

'The tiger that isn't'Mathematics is the language of science. Clear, simple, fundamental. Perhaps because of this purity, numbers can be the slaves of spin-doctors, politicians and an unscrupulous media.

'Chases and escapes'I've read several of Paul Nahin's books before (see my review of Dr. Euler's fabulous formula in Plus) and this is no exception to his excellent style. The strategies of pursuit and evasion have fascinated mathematicians for centuries. One of the earliest problems was posed by Frenchman Pierre Bouger in 1732.

'Euler's Elements of Algebra'Leonhard Euler was one of the greatest and most prolific mathematicians of all time. His work was of vital importance to a bewildering variety of fields, many of which he himself created

'Nonplussed!' A review of a book as good as this must either repeat the positive adjectives other reviewers have used, or require a very large thesaurus.

'The art of mathematics' Imagine that on your first day training to be a builder you are given a set of toy blocks with which to build a model house.

'Life in the Universe'Given that 14 billion years have elapsed since the birth of the Universe and that the cosmos contains a mind-boggling 10

^{24}stars, can Earth really be the only planet in the entire Universe to contain life?
'Flatland: the movie'The movie is based on one of the best mathematical tales ever written. Inhabiting a two-dimensional world populated by polygons and ruled by circular tyrants, a bright young hexagon, through sheer mathematical willpower, imagines a third dimension.

'Mathematics and common sense'The basis of this wonderful book came in a series of questions about modern maths sent to Philip Davis by a friend of his, Christina.

'Why beauty is truth'I suspect maths in primary school would be greeted with far more enthusiasm if students had Ian Stewart as a teacher. Any man who can explain electromagnetism, gravity and atomic nuclear forces in terms of a piggy fridge magnet and a smashed kitchen plate is, surely, a communicator to be reckoned with.

'A beautiful math'Sylvia Nasar told the story of John Nash's troubled life in her book

*A Beautiful Mind*, although probably better known as the film with Russel Crow.
