Welcome to Larry
Marschall's web pages. I am Professor of Physics, Emeritus at Gettysburg
College where I taught
courses in astronomy and physics for 43 years, as well as occasional courses in the
history and philosophy of science and science writing. My research includes
observational studies of stellar evolution, including binary stars, exoplanet transits, and supernovae, studies of asteroids,
and astronomy education. I've also traveled to many solar eclipses,
since 1980, both for pleasure and for research. I'm the Principal
Investigator of Project CLEA, which develops innovative laboratory exercises
for astronomy classes. I'm also an active popular science writer, author of
three books and many articles, as well as a regular columnist for Natural
History magazine (and before that, for The Sciences), and a deputy press officer of the American Astronomical Society.
