Professor Andy Freed from the Department of Earth Atmospheric and Planetary Sciences talks about asteroid impacts and craters on the moon and the Earth. He uses finite element modeling for computer modeling to look at the formation and evolution of craters. Andy explains that there is still heat in the core of the Moon and it can take millions of years for planetary bodies to cool down. He applied his expertise in finite element modeling of rockets to geophysics and now to planetary science. Andy explains about stress transfers of earthquakes that cause sequences of earthquakes. Andy teaches two of the most demanded elective classes on campus. Geosciences in the Cinema looks at the science in popular movies. EAPS 105 Planets which trace the origin of all elements (and even our human bodies!) to supernovas and stardust.
