Open to the Public
Join Oxford science enthusiasts at the Lusa Pastry Cafe' on Jackson Avenue for our next Oxford Science Cafe'.
Dr. Theresa Levitt (University of Mississippi) will present: "A Short Bright Flash: Augustin Fresnel and the Invention of the Modern Lighthouse."
In 1822, France’s most creative and unconventional physicist, Augustin Fresnel, invented a new lens that transformed not only the way lighthouses operated, but the very possibility of what they could do. Previously, lighthouses used metal mirrors and could typically be seen from 5 to 8 miles away, which was not quite far enough for shoals that often stretched up to 10 miles into the sea. This talk covers Fresnel’s solution to this problem using an innovative design of glass prisms, his struggle to meet the engineering challenges of the demanding technology, and the rise of the golden age of lighthouses.
When: Tuesday, January 21, 2013, 6pm - 7pm.
Where: Lusa Pastry Cafe', 2305 West Jackson Avenue, Suite 211 Oxford, MS, 38655.
