Description: The history of science is a chronicle of revolutionaries and the Earth Sciences are not without their radical thinkers. In 1911 Alfred Wegener published a book in which he proposed the concept of continental drift. Two hundred million years ago, he contended, an intact supercontinent began to break apart (like pieces of an ice flow) and the continental fragments drifted to their present position. The response of the scientific establishment to his hypothesis was ridicule and derision. Depicts his demise and eventual vindication in the last decade.-
