Solitaire is a game played with pegs in a rectangular grid. A peg may jump horizontally or vertically, but not diagonally, over a peg in an adjacent square into a vacant square immediately beyond. The peg which was jumped over is then removed. 
Emmy Noether, pioneering female mathematician, died 80 years ago.

The harmonic series is far less widely known than the arithmetic and geometric series. However, it is linked to a good deal of fascinating mathematics, some challenging Olympiad problems, several surprising applications, and even a famous unsolved problem. John Webb applies some divergent thinking, taking in the weather, traffic flow and card shuffling along the way.

There are many errors that can occur when numbers are written, printed or transferred in any manner. Luckily, there are schemes in place to detect, and in some cases even correct, such errors almost immediately. Emily Dixon takes a break and discovers that codes are not just for sleuths.

'Of the myriad strategems I employ to avoid useful work, the one I most enjoy is to envision how scientists of earlier eras would have made use of modern computers.' John L. Casti tells us how today's mathematicians are using computers to carry on the work of turnofthecentury polymath d'Arcy Wentworth Thompson, who showed how mathematical functions could be applied to the
shape of one organism to continuously transform it into other, physically similar organisms.

f you're flicking casually through the books in the "popular mathematics" section of your local bookshop, and see this book but fail to read the subtitle, you might well think that its theme is that some people are born with a "maths gene", and some without  and that possession of this gene is the major factor in determining who can do maths, and who can't.
