This book provides an introduction to Kurt Godel's theorems through a collection of puzzles interspersed with an account of symbolic logic. Godel's argument has been transferred from the formal domain of mathematical systems in an attempt to make its essential ideas more accessible to the general reader. The primary emphasis is on belief systems and how they are related to systems of mathematics. This leads to the subject of possible world semantics which plays a role in computer science and artificial intelligence.

Tricks, Games, and Puzzles With Matches

Maxey Brooke

Dover Pubns | 1973 | 64 páginas | pdf | 267 kb

With a handful of matches you can challenge yourself and your friends to match hundreds of match tricks, games and puzzles. The quipment is simple and can easily be carried with you. The tricks, games and puzzles range from the simple to the advanced. No matter how many match tricks and puzzles you have previously done you are sure to find new twists, new challenges in the puzzles in this collection.
There are classic match problems, problems by foremost puzzlers, and a number of Makey Brooke's own creations. There is match-arithmetic, where you are required to balance equations by removing or adding matches, including a few that require advanced mathematical notation. There are match spellings, match story games, tricks that involve kitchen matches, paper match books and match boxes, and simple mathematical games you can play with matches. A rich selection of match constructions, in which you are required to build, unbuild, or reconstruct squares and other geometrical units by simply moving matches, is made even richer by the inclusion of a special selection from T.R. Dawson's works. The solutions section gives complete information for solving the puzzles plus material on winning games and working the tricks.

The Gödelian Puzzle Book: Puzzles, Paradoxes and Proofs by Raymond M. Smullyan



Raymond M. Smullyan

Dover Publications | 2013 | 288 páginas | rar - epub | 557 kb

link (password: matav)

These brand-new recreational logic puzzles provide entertaining variations on Gödel's incompleteness theorems, offering ingenious challenges related to infinity, truth and provability, undecidability, and other concepts. Created by the celebrated logician Raymond Smullyan, the puzzles require no background in formal logic and will delight readers of all ages.
The two-part selection of puzzles and paradoxes begins with examinations of the nature of infinity and some curious systems related to Gödel's theorem. The first three chapters of Part II contain generalized Gödel theorems. Symbolic logic is deferred until the last three chapters, which give explanations and examples of first-order arithmetic, Peano arithmetic, and a complete proof of Gödel's celebrated result involving statements that cannot be proved or disproved. The book also includes a lively look at decision theory, better known as recursion theory, which plays a vital role in computer science.

Unique and highly original, Mathematical Byways is a work of recreational mathematics, a collection of ingenious problems, their even more ingenious solutions, and extensions of the problems--left unsolved here--to further stretch the mind of the reader. The problems are set within the framework of three villages--Ayling, Beeling, and Ceiling--their inhabitants, and the relationships (spacial and social) between them.The problems can be solved with little formal mathematical knowledge, although most require considerable thought and mental dexterity, and solutions are all clearly expounded in non-technical language. Stimulating and unusual, this book proves what Hugh ApSimon has known all along: mathematics can be fun!
