Jefferson Lab announces 2004 Spring Science Series events

The Dept. of Energy's Jefferson Lab Spring 2004 Science Series events begin Tuesday, February 24, with science writer Nigel Hey
presenting "Worlds Beyond the Matrix." In his presentation, learn about the exploration of space and see images gathered by probes
and telescopes. He will venture into topics ranging from "What do those huge canyons on Mars look like?" to "What is waiting for us
on the surfaces of the other planets in our solar system?" He will discuss the technologies currently being used to explore the
depths of space.

"The Physics of Stock Car Racing from a NASCAR Champion's Perspective," with Lawrence Livermore National Lab physicist and stock
car driver, Scott Winters, is set for Tuesday, March 9. This two-time NASCAR Champion will overview the physics of stock car racing
from a driver's perspective. Topics will feature various technical aspects of stock car racing, such as, tires, mechanical
suspension, aerodynamics and engines with an emphasis on NASCAR-style cars. Catch this exhilarating, "fast paced" lecture, complete
with video footage.

Then University of Washington's Scott Eberhardt, professor of Aeronautics and Astronautics, discusses "Understanding Flight: A
Physical Description of How Airplanes Fly" on Tuesday, March 23. Have you ever wondered how a Boeing 747 can even get off the
ground? Or how airplanes fly upside down? What makes a wing efficient? These questions can be answered when lift is developed in
terms of Newton's laws. Through the application of Newton's three laws, the audience will gain insight into conclusions of
aerodynamics without the need for analysis. Come to understand how and why the wing is able to carry such a large load.

The final event of the season will be Tuesday, April 20, and features William Hammack, of the University of Illinois and National
Public Radio host of the "Engineering Guy" program, discussing "The Hidden World of Technology." From the moment the clock radio
comes on in the morning to the time we shut off the last light at night, a hidden web of technology supports and sustains us.
Hammack takes the first half hour of his day to show his audience the complex web of technology underlying it. In addition to the
technical aspect, he explores the social, political, economic and cultural context of the material things surrounding us.

Science Series presentations begin at 7 p.m. in Jefferson Lab's CEBAF Center auditorium, located at 12000 Jefferson Ave., Newport
News. The presentations last about one hour with a question and answer period at the end. The events are free and open to anyone
interested in learning more about science. 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 and security guards may perform ID and vehicle checks. For more
