(August 2, 1820–December 4, 1893), was a British physicist and philosopher. He was the director of the Royal Institute. His scientific studies included: the flow of glaciers; transmission and radiation of heat; and “the Tyndall effect,” which demonstrates how light is scattered by microscopic particles such as dust and colloids in suspension. In Fragments of Science, Vol. II, “Professor Virchow and Evolution,” John Tyndall stated:
Religious feeling is as much a verity as any other part of human consciousness; and against it, on the subjective side, the waves of science beat in vain.2553
