Professor Stewart's Cabinet of Mathematical Curiosities

School maths is not the interesting part. The real fun is elsewhere. Ian Stewart has collected the most enlightening, entertaining and vexing 'curiosities' of maths over the years...Now, the private collection is displayed in his cabinet. There are some hidden gems of logic, geometry and probability, a pop up dodecahedron, the real reason why you can't divide anything by zero and some tips for making money by proving the obvious. Pull out the drawers of the Professor's cabinet and who knows what could happen...
