Alexander Keewatin Dewdney (born August 5, 1941 in London, Ontario) is a Canadian mathematician, computer scientist, author, filmmaker, and conspiracy theorist. Dewdney is the son of Canadian artist and author Selwyn Dewdney, and brother of poet Christopher Dewdney.
Art and fiction
In his student days, Dewdney made a number of influential experimental films, including Malanga, on the poet Gerald Malanga, Four Girls, Scissors, and his most ambitious film, the pre-structural Maltese Cross Movement. Margaret Atwood wrote that a poetry scrapbook by Dewdney, based on the Maltese Cross Movement film, "raises scrapbooking to an art".
He has also written two novels, The Planiverse (about an imaginary two-dimensional world) and Hungry Hollow: The Story of a Natural Place. Dewdney lives in London, Ontario, Canada where he holds the position of Professor Emeritus at the University of Western Ontario.
Computing, mathematics, and science
Dewdney has written a number of books on mathematics, computing, and bad science.
Dewdney followed Martin Gardner and Douglas Hofstadter in authoring Scientific American magazine's recreational mathematics column, renamed to "Computer Recreations", then "Mathematical Recreations", from 1984 to 1991. He has published more than 10 books on scientific possibilities and puzzles. Dewdney was a co-inventor of programming game Core War.
During the last 20 years, Dewdney has worked on biology, both as a field ecologist and as a mathematical biologist, contributing a solution to the problem of determining the underlying dynamics of species abundance in natural communities.
Dewdney is a member of the 9/11 Truth movement, and has theorized that the planes used September 11, 2001 Terrorist Attacks had been emptied of passengers and were flown by remote control. He based these claims in part on a series of experiments (one with funding from Japan's TV Asahi) that, he claims, show that cell phones do not work on airplanes, from which he concludes that the phone calls received from hijacked passengers during the attacks must have been faked. However, these claims are part of a fringe view of the terrorist attacks that is not accepted by any well-established scientific organization such as the National Institute of Science and Technology.
