Martin Gardner is the name that always comes to mind when one thinks of Mathematical Recreations. Anyone who ever read Scientific American magazine will remember his column in every issue. He wrote the column for 25 years and made puzzle lovers of millions of readers. His fans ran the gamut from those with a very elementary background in mathematics to those with a high degree of knowledge. What he did was to make mathematics something to enjoy and use as a recreational pursuit. Over the years, he wrote about 70 books, many that have been popular for a long time. In this book, The Colossal Book of Short Puzzles and Problems, he has chosen 340 puzzles from his columns of over 25 years. He has selected simple problems as well as medium and difficult. Each problem is supplied with an answer or solution. Often, answers in puzzle books are sketchy but here we not only get an answer but also a good idea and explanation on arriving at the solution. The most interesting thing about this book is that it is geared to all levels of puzzle solvers (OMNIHEURISTS). I am sure that someone who has worked only a few puzzles and who hasn’t will find many quite easy and in a short time will progress to those with more challenge due particularly to the answer explanations. At the same time, those with a lot of experience will find plenty to amuse themselves. Along with a pick of some of the best of the columns over the years; Gardner has included 12 of the best brainteasers to have come his way since he stopped writing the column in 1986. Also, we are given a list of all the other books that Martin Gardner wrote over the years. Along with that, there is a list of selected titles for those interested in more in the world of Recreational Mathematics. If you like Mathematical Recreations or puzzles of any kind, take a look at this book and you’ll surely want to own it. You can purchase this book at Amazon.
