Two dimensional engineering, first popularized in Edwin Abbot's 1884 novel Flatland, was brought up to date and given a rigorous scientific treatment by Alexander Dewdney, a Canadian mathematician and computer scientist. He wrote an influential novel, The Planiverse, in 1984 - one hundred years after Abbot's pioneering Flatland - that remains in print. Dewdney also organized two symposia that resulted in diverse papers on the possible biology, physics, chemistry, and culture of a two dimensional universe. A few years aggo Chris Yonge collaborated with Professor Dewdney to turn these symposia into PDF form and the results (each about a 50Mb file) can be obtained on request.
