David Orrell

David Orrell (born in Edmonton) is a Canadian mathematician and author who is living in Vancouver, British Columbia, Canada. He received his doctorate in mathematics from the University of Oxford. His work in the prediction of complex systems such as the weather and climate has been featured in New Scientist, London’s Financial Times, and BBC Radio. 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 in the area of systems biology. He is the son of theatre historian and English professor John Orrell.

Published in January 2007, his book Apollo's Arrow : The Science of Prediction and the Future of Everything has reached the top 20 of the bestsellers list of Amazon.ca.
