Professor Philip Bucksbaum of Stanford University will present a free public science lecture at 8:00 PM in Grand Ballroom A/B at the Ft. Lauderdale Convention Center entitled: Molecular movies: how to make them and what are they good for?

The lecture will describe how lasers can be used to view the internal motion of electrons and ions in small molecules, motion that is far too fast to be captured by conventional high speed cinematography. Within molecules, the time scale of motion is determined by the molecular bond lengths (Angstroms) and binding energies (electron-volts) to be millionths of billionths of seconds (femtoseconds) or shorter. Recent advances in laser technology have led to pulses of light so short and bright that for the first time we can consider lasers as strobe lights to make movies of internal motion in molecules. To interpret these stroboscopic motion pictures of the internal motion in atoms and small molecules, we must reconsider the concepts of motion and pictures on the quantum scale. Prof. Bucksbaum will show how new laser tools are used to track the internal motion in atoms and molecules, and reveal the underlying internal quantum mechanical mechanisms responsible for them.

The lecture will begin at 8 PM on Tuesday May 29 as part of the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society.
