Particle Physics Today Today, we stand at a crossroads in the history of science … After 50 years, we have reached the point where we can ask bold new questions about the structure of matter, energy, space and time

Particle Physics Today We can look forward …. “.... like stout Cortez, when with eagle eyes He star’d at the Pacific – and all his men Look’d at each other with a wild surmise – Silent, upon a peak in Darien.” John Keats

String Theory String theory predicts extra dimensions Where are they? How many are there? How are they hidden? What are their shapes and sizes? Such questions are moving from science fiction to science fact

Atoms for Peace President Dwight D. Eisenhower “I know that the American people share my deep belief that if a danger exists in the world, it is a danger shared by all; and equally, that if hope exists in the mind of one nation, that hope should be shared by all.... [The] United States pledges before you... to devote its entire heart and mind to finding the way by which the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life.”
