Alcuni sanno anche della sua mania di fotografare bambine, spingendosi fino a definirlo un depravato sessuale represso (anche se non si hanno notizie di alcun suo atto contro la pubblica decenza). Ma la sua personalità è molto più variegata, come si può leggere in questa biografia che racconta la sua vita a tutto tondo, compreso il suo lavoro come fotografo (uno dei più importanti del XIX secolo), di matematico (onesto, pur senza essere fuori categoria: importanti i suoi lavori sui sistemi di voto) e di persona comunque in prima fila nella società dell'epoca. La traduzione (disclaimer: conosco Franco Ligabue da una vita) è stata un mezzo tour de force per rendere le rime e i giochi di parole dell'originale, per il sollievo del lettore non madrelingua inglese. Most people know Charles Dodgson as his pen name Lewis Carroll and his work "Alice in Wonderland"; however, he was also a brilliant mathematician. This book documents this life from childhood through his years at Oxford University. In addition to biographical information, Robin Wilson includes many of Dodgson's puzzles and math problems for the reader to solve. The book turns from a biography to a book of logic puzzles. After reading this book, I had to watch Alice in Wonderland again as it gave me an entirely new perspective on the story. The illustrations are a must in this book if the reader is not familiar with the proofs explained in the book. The author also uses many primary sources from Dodgson's writings. Having assigned students mathematicians on which to complete biographies, I have used this book as a reference. Given it can be a difficult read for junior high students, I usually pick out which sections would given them the most relevant information. There are also many puzzles and problems that can be used as weekly challenge problems for students. An interesting biography of a fascinating man. Prior to reading this book, I had no idea that Dodgson was a pioneer of photography, for example. The book ties together Dodgson's various passions and the currents in his life quite well. However, about three-quarters of the way through the book, it loses its narrative energy, and the book becomes something of a slog to finish. A short biographical treatment of Charles Dodgson (pen name Lewis Carroll) containing several examples of his mathematical interests. I was interested to learn how the Alice series came to be written as a logical and natural result of his character since childhood. He was a multi-talented man, according to author, who would be perhaps best known for his photography, if it were not for the Alice books. Yet he was an original and brilliant mathematician, as well as a teacher of mathematics constantly searching for ways to motivate and explain his subject. I found the mathematical materials of great interest, but they could have been weeded down into fewer examples. There are fine helps for the reader, such as maps, illustrations, photographs, and notes. One small fact I'll remember: n the pronunciation of 'Dodgson,' the 'g' is silent. inga recensioner | lägg till en recension
As Wilson demonstrates, Carroll--who published serious, if occasionally eccentric, works in the fields of geometry, logic, and algebra--made significant contributions to subjects as varied as voting patterns and the design of tennis tournaments, in the process creating imaginative recreational puzzles based on mathematical ideas. --from publisher description.
