Martin Gardner siempre se definió como un ilusionista "aficionado", pero fue el creador de muchos efectos que otros magos "profesionales" recrean. En sus artículos y libros aparecen con frecuencia sugerentes juegos de magia, y el término "matemagia", que fusiona las matemáticas con la magia, fue inventado por él. A través de ingeniosos trucos, Gardner despertó el interés por las matemáticas en muchos niños que hoy día son aficionados a ellas e incluso las enseñan y estudian, como los autores de este libro.Este conjunto de artículos supone un atractivo material complementario para los docentes de matemáticas de Primaria y Secundaria. Con esta obra, la Real Sociedad de Matemáticas de España quiere contribuir a la celebración del centenario de Martin Gardner, y rendir así un sincero homenaje a este gran matemago.
Every mathematician (beginner, amateur, and professional alike) thrills to find simple, elegant solutions to seemingly difficult problems. Such happy resolutions are called 'aha! solutions,' a phrase popularized by mathematics and science writer Martin Gardner. Aha! solutions are surprising, stunning, and scintillating: they reveal the beauty of mathematics. This collection includes one hundred problems in the areas of arithmetic, geometry, algebra, calculus, probability, number theory, and combinatorics. The problems start out easy and generally get more difficult as you progress through the book. A few solutions require the use of a computer. An important feature of the book is the discussion of related mathematics that follows the solution of each problem. This material is there to entertain and inform you or point you to new questions.

In this new edition of a wordless modern classic, a frog picks a beautiful flower. When a mouse sees him with it, his jealousy overcomes him, and he grabs it for himself. Then Frog’s friends chase the mouse away. But before the frogs can celebrate, a counter-attack from Mouse's friends surprises them—and the conflict soon escalates into a full-blown war. When the dust finally clears, all either side can ask is: Why? With an afterword by children’s literature expert Leonard S. Marcus, this seemingly simple book is an invaluable way to talk to young children about conflict and warfare.
Unexpected rhymes such as half/giraffe and towel/owl show the silly sounds of everyday words.
