'[...] la inteligencia es el resultado de la herencia (80 por ciento, más o menos) y de la educación (el restante 20 por ciento) [...]'
'Lo fundamental es que haya un período de libertad con respecto a las exigencias del problema planteado, un período de descanso e inclusive de ocio.'
'Si por un tiempo me desentiendo de una dificultad, cuando retomo el asunto, con frecuencia suelo comprobar que soy capaz de superarla con sorprendente facilidad.'
This didn't have anything in it that's not already in hundreds of puzzle books. Certainly nothing original--I'm completely sure the author didn't invent a single puzzle for this book. Moreover, the explanations are clumsy and unenlightening. Unforgivably, there are important assumptions missing at a few vital places. For instance, in the famous SEND + MORE = MONEY puzzle, there's no mention that the M's can't be zeroes, nor that two different letters can't stand for the same number. So 0000+0000=00000 solves the puzzle, from the rules given.
I guess if this was the first puzzle book you ever saw in your life, and if you've never heard a riddle before, this would be enjoyable.
I completely forgot about these books until I saw them on a friend's shelf. I remember reading them in the 70s and 80s. My father bought them and my brother and I were fascinated by the riddles and puzzles in them. Really cool books that are entirely appropriate for elementary age kids and adults - particularly ones that are intellectually curious!
Educational and entertaining. How to determine the height of a building using a barometer? Too obvious - better answer, hold it level with the top edge, drop and time until it smashes on ground, use laws of gravity to calculate height :)
