Boris Kordemsky

Un Elefante Y Un Mosquito Boris Kordemsky

Here is the second part of Boris Kordemsky's classic that was published in 1954 and had a great impact on successive generations of popularizers and lovers of the logical game all over the world. Martin Gardner himself was in charge of translating and adapting it for Western readers. Today, it is still considered a cult compilation, a book that lasts a lifetime. Lavishly illustrated with over 200 diagrams and amusing sketches by Yevgeni Kostantinovich Argutinsky, this second volume will provide weeks of stimulating entertainment. Kordemsky presents us with challenges like the following: two motorcyclists start at the same time, cover the same distance and return home at the same time. But one rides twice as long as the other rests during the trip, and the other rides three times as long as the first rider rests during the trip. Who rides faster? Algebra exercises, arithmetic tricks, magic squares, curiosities about numbers and geometric calculations will allow you to do brain gymnastics while enriching your general culture.
