A. K. Dewdney
Alexander Keewatin Dewdney (born August 5, 1941) 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. He was born in London, Ontario. 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". The Academy Film Archive has preserved two of Dewdney's films: "The Maltese Cross Movement" in 2009 and "Wildwood Flower" in 2011. 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. He also founded and edited a magazine on recreational programming called "Algorithm" between 1989 and 1993. 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". Since the nineties, 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. Conspiracy theories. Dewdney is a member of the 9/11 truth movement, and has theorized that the planes  used in the September 11 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.
