Alexander Dewdney

Alexander Keewatin Dewdney (born August 5, 1941 in London, Ontario) is a Canadian mathematician, computer scientist and author who has written a number of books on mathematics, computing, and bad science. He has also written two works of fiction, 'The Planiverse' and 'Hungry Hollow', the first about an imaginary two-dimensional world, the second about natural areas. Dewdney lives in London, Ontario, Canada where he holds the position of Professor Emeritus at the University of Western Ontario. Dewdney is the son of Canadian artist and author Selwyn Dewdney, as well as the brother of poet Christopher Dewdney.

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".

Dewdney followed Martin Gardner and Douglas Hofstadter in authoring Scientific American's recreational mathematics column, renamed to "Computer Recreations", then "Mathematical Recreations", from 1984 to 1991. These have been collected into 3 books of mathematical recreations.

In 2003, Dewdney conducted three aerial experiments on cellphone communication, in attempts to prove that cellphones will not function on passenger aircraft when in flight. The last experiment was filmed and broadcast by Japan's ASAHI Network.

For the last 20 years, Dewdney has concentrated on biology, both as a field ecologist and as a mathematical biologist, contributing a solution to the thorny problem of determining the underlying dynamics of species abundance in natural communities.
