Alexander Dewdney

From Wikipedia, the free encyclopedia

Alexander Keewatin Dewdney (born August 5, 1941 in London, Ontario) is a Canadian mathematician, computer scientist and philosopher who has written a number of books on the future and implications of modern computing. He has also written one work of fiction, The Planiverse. Dewdney lives in London, Ontario, Canada where he holds the position of Professor Emeritus of the University of Western Ontario.

In his early life, as "Keewatin Dewdney," he made a number of influential experimental films, including "Malanga," on the poet Gerard Malanga, as well as "Four Girls," "Scissors," and his most ambitious film, the pre-structuralist "Maltese Cross Movement." "Malanga," "Four Girls" and "Scissors" may be rented in 16mm from the Film-Makers' Cooperative in New York City. More about Dewdney's early film work can be found in Wheeler Winston Dixon's book "The Exploding Eye," a history of experimental film in the 1960s.

Dewdney followed Martin Gardner and Douglas Hofstadter in authoring Scientific American 's recreational mathematics column, which he renamed to "Computer Recreations", then "Mathematical Recreations", from 1984 to 1993 (with the last few appearing in Algorithm). These have been collected into 3 books. The subjects include computer viruses, Core Wars, finite automata like Conway's Game of Life, brown noise, the game of Alak, Tinkertoy and spaghetti sorting.

Dewdney has been a Muslim for over 35 years.[1] He has developed hypotheses which sharply disagree with the official version of the events surrounding the September 11, 2001 Terrorist Attacks (see external links below).
