PHY133 - Using a whirlygig to calculate the mass of the earth and the sun.

What can we do? What should we do? What are we called to do? How can we be most effective?

Consider joining the PhysAstro Department as we wrestle with these questions, and more, during our Spring Seminar Series on Tuesdays this semester.

Our boys couldn't come home without dropping some more knowledge at the AAS, as Professor Jess Vriesema shared his work on an educational tool aimed at enriching student learning in Calvin PhsAstro courses - The Solar Motion Simulator.

Professors Larry Molnar and Jess Vriesema, along with junior Physics major Rigel Reynolds, took part in the annaul meeting of the American Astronomical Society, presenting their summer research on Contact Binary Stars at a gathering of some 2500 astronomers in Phoenix, Arizona today.

They also hit the trails, doing a little mountain climbing, during their escape from the Michigan winter weather.
