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

We can look forward . .... like stout Cortez,
when with eagle eyes He stard at the Pacific
and all his men Lookd at each other with a wild
surmise Silent, upon a peak in Darien.

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
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.
President Dwight D. Eisenhower
