Antimatter. The Big Bang. Ghostly neutrinos. The public is invited to spend Saturday mornings this spring with UT’s Department of Physics and Astronomy learning about intriguing and newsworthy science topics.

Saturday Morning Physics will feature physics faculty talking about their areas of expertise and how they pertain to the world around us.

The series kicks off February 4 with Professor Soren Sorensen, an expert in experimental nuclear physics. His lecture, “What is Everything Made Of? The Quest for Building Blocks of the Physical Universe,” will look at molecules, atoms, and other matter, and explain how scientists constantly search for new discoveries. Sorensen will end the lecture with the discussion of these fundamental building blocks and how they relate to superstring theory.

Sorensen attended the University of Copenhagen and the Niels Bohr Institute in his home country of Denmark. After earning his doctorate, he spent a year at Oak Ridge National Laboratory and later became an assistant professor at UT in 1984. While in high school in Denmark, Sorensen attended similar lectures at the University of Copenhagen. He attributes those experiences to his current success in his field of study.

“I was fascinated by all the things I learned that were way beyond what I was taught in high school,” Sorensen said. “As a result I became convinced that studying nature as a physicist would be a challenging but very exciting career goal. I have never regretted that decision. My work as a nuclear physicist has turned out to be even more rewarding and fascinating than I dreamed about.”

Sorensen’s lecture, as well as the other presentations, will be held from 10 to 11:15 a.m. with questions and discussion from 11:15 a.m. to noon in Room 307 of the Science and Engineering Research Facility (SERF). The April 8 lecture will be in Room 415 of the Nielsen Physics Building. Limited parking will be available in the 11th Street Garage.
