John Tuzo Wilson: a Canadian who revolutionized Earth Sciences

Feature articles in the 50th issue of CJES review Wilson's scientific contributions and point to new directions in global earth science based on Wilson's legacy, but of particular interest may be Paul Hoffman's description of how Tuzo Wilson was able to discard his anti-plate tectonic model of Earth history, that he had held dear for more than 20 years, and accept the new theory of plate tectonics when it best fit the data. What does it take for scientists' to change their fundamental understanding of nature, anyway?
