Alexander Dewdney

Alexander Keewatin Dewdney (born August 5 1941 in London, Ontario) is a Canada mathematician, computer science, and philosophy 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, Ontario, Canada where he holds the position of Professor Emeritus of the University of Western Ontario.

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 the game of Life, brown noise, the game of Alak, Tinkertoy and spaghetti sorting.

He has developed hypotheses which sharply disagree with the official version of the events surrounding the September 11, 2001 Terrorist Attacks (see #External links).
