A fillip to the palate of the jaded reader who pushes mathematics aside as none of his concern, but who pretends to recognize the fact that he has a modern viewpoint and a flexible understanding. This book should accomplish at least two things: -- it should show the ""man in the street"" -- otherwise T. G. Mits -- that modern mathematics is a tool for meeting the changing world, that it has value in applying abstract ideas to the modern four dimensional world, that is concerned not only with the gadgets science gives us, but the philosophy of the processes. A man trying to think without mathematics is a helpless child; mathematics shows what to keep, what to discard (in ways of thinking as in other things). The mathematical problems are entertainingly presented, even for the unmathematically inclined, and should spur them (us) on to going further behind the scenes. Amusing, stimulating, original.
