David Orrell

David John Orrell (born 1962 in Edmonton) is a Canadian mathematician and author who is living in Oxford, England. He received his doctorate in mathematics from the University of Oxford. His work in the prediction of complex systems such as the weather, genetics and the economy has been featured in New Scientist, London’s Financial Times, Adbusters, BBC Radio, and CBC TV. His theory that errors in weather forecasts are due not to chaos (the "butterfly effect") but to model error stirred up a storm of debate in meteorological circles. He now conducts research and writes in the areas of systems biology and economics, and runs a mathematical consultancy Systems Forecasting. He is the son of theatre historian and English professor John Orrell.

His book Apollo's Arrow : The Science of Prediction and the Future of Everything was a national bestseller and finalist for the 2007 Canadian Science Writers' Award. Economyths: Ten Ways Economics Gets It Wrong was a finalist for the 2011 National Business Book Award.
