The 1975 CBC Massey Lectures - "Limits To Science"

J. Tuzo Wilson has been a chief exponent of the theory of continental drift, a subject of vigorous scientific controversy. Two decades ago, the theory was almost universally rejected by geophysicists. It is now almost universally accepted and is the most important explanation we have about the history of earth's surface.

J. Tuzo Wilson has written more than 100 scientific papers and five books. He is Director General of the Ontario Science Centre, Fellow at the Royal Society of London and Vice President of the Royal Canadian Geographical Society.
