Jefferson Lab's Spring 2007 Science Series features two lectures in February

Jefferson Lab will host two Spring Science Series lectures during February 2007. The first event is set for Tuesday, February 20, and will feature David Powars, with the U.S. Geological Survey (USGS), discussing the Chesapeake Bay Impact Crater. He will share with the audience, recent research from a core hole more than a mile deep in the central zone of this 35.5-million-year-old impact crater buried beneath the lower Chesapeake Bay and how it is still affecting the region today.

Then prepare for the thrill of competition -- mental competition -- on Wednesday, February 28, when Dr. Richard Berg, with the University of Maryland Physics Department, conducts The Physics IQ Test for the audience's enlightenment and entertainment. The audience will vote on the outcome of physics brainteaser-type questions, which will then be answered by Berg as he performs demonstrations or experiments that will answer the questions.

Each presentation begins at 7 p.m. in Jefferson Lab's CEBAF Center auditorium, located at 12000 Jefferson Ave., Newport News, Va. The programs are free and open to anyone interested in learning more about science; they last about one hour and include a question and answer period at the end. For security purposes during Science Series events, enter at Jefferson Lab's main entrance (Onnes Dr.). Everyone over 16 is asked to carry a photo ID.  Security guards may perform ID, backpack, purse and vehicle checks. For more information, visit
