WATERLOO, ON, Jan. 11, 2012 - We shovel them, we hide from them, and we rejoice when they give us an extra day's holiday. In a Canadian winter, the snowflake is everywhere. But how do they form? What do their complex and striking shapes tell us about nature? Looking back to our childhood, is it true that no two are exactly alike? On Wednesday, February 1, as part of Perimeter Institute's Public Lecture Series presented by Sun Life Financial, Kenneth Libbrecht, Physics Professor at Caltech, takes us on a visual journey to expose the secret life of a snowflake. Explore how the intricate, symmetrical and magnificent patterns emerge in nature's frozen art through a series of scientific data and spectacular photographs. Kenneth Libbrecht knows perhaps more than anyone should about the science of snowflakes. Libbrecht is a professor and Chairman of the Physics Department at Caltech, following his PhD in physics from Princeton University. In the mid-1990s, Libbrecht's extensive research of the molecular dynamics of crystal growth led him back to his roots in North Dakota for a detailed study of how ice crystals - the snowflake - quite literally appear out of thin air. Kenneth Libbrecht's lecture, entitled "The Secret Life of a Snowflake: An Up-Close Look at the Science and the Splendour of Nature's Frozen Art" will be held Wednesday, February 1 at 7:00 PM ET in Waterloo, Ontario. Tickets will be available starting Monday, January 16, 2012. Further details can be found at www.perimeterinstitute.ca.
