Download or read book Serious Fun with Flexagons written by L.P. Pook and published by Springer Science & Business Media. This book was released on 2009-08-04 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: A flexagon is a motion structure that has the appearance of a ring of hinged polygons. It can be flexed to display different pairs of faces, usually in cyclic order. Flexagons can be appreciated as toys or puzzles, as a recreational mathematics topic, and as the subject of serious mathematical study. Workable paper models of flexagons are easy to make and entertaining to manipulate. The mathematics of flexagons is complex, and how a flexagon works is not immediately obvious on examination of a paper model. Recent geometric analysis, included in the book, has improved theoretical understanding of flexagons, especially relationships between different types. This profusely illustrated book is arranged in a logical order appropriate for a textbook on the geometry of flexagons. It is written so that it can be enjoyed at both the recreational mathematics level, and at the serious mathematics level. The only prerequisite is some knowledge of elementary geometry, including properties of polygons. A feature of the book is a compendium of over 100 nets for making paper models of some of the more interesting flexagons, chosen to complement the text. These are accurately drawn and reproduced at half full size. Many of the nets have not previously been published. Instructions for assembling and manipulating the flexagons are included.

Download or read book Sit and Solve Cross Number Puzzles written by Henry Hook and published by Sterling Publishing Company, Inc.. This book was released on 2006-03 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Love numbers? Then this one’s for you. It offers wildly challenging, brain-busting math puzzles that really test your arithmetic logic. Like a regular crossword, it features a grid that you have to fill in by solving clues. But here, one clue may refer you to another one, which you’ll then have to figure out first to go further. For example, the solution for 21 Down might be: 34 Down Septupled. You’ll then have to go to 34 Down to see what it says. Nothing’s obvious, so you’ll have to think hard and do some smart calculations. In case you need a little help, there are "starting hints” that give you a few answers to get you going.

Download or read book Flexagons Inside Out written by Les Pook and published by Cambridge University Press. This book was released on 2003 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexagons are hinged polygons that have the intriguing property of displaying different pairs of faces when they are flexed. Workable paper models of flexagons are easy to make and entertaining to manipulate. Flexagons have a surprisingly complex mathematical structure and just how a flexagon works is not obvious on casual examination of a paper model. Flexagons may be appreciated at three different levels. Firstly as toys or puzzles, secondly as a recreational mathematics topic and finally as the subject of serious mathematical study. This book is written for anyone interested in puzzles or recreational maths. No previous knowledge of flexagons is assumed, and the only pre-requisite is some knowledge of elementary geometry. An attractive feature of the book is a collection of nets, with assembly instructions, for a wide range of paper models of flexagons. These are printed full size and laid out so they can be photocopied.
