For people outside AU, a Zoom invitation to each forum can be obtained during the week it is scheduled by emailing Marilyn Saxton at saxtonmj@alfred.edu. The forum will take place on Thursday March 17th from 12:10 to 1:00.


Speaker:  Otto Muller

Topic:  Some Interesting Points about Size, Shape and Rotation of the Earth

When did we first learn that the Earth was round?  How has our knowledge of its size and shape changed over time?  What point on the Earth’s surface is the furthest from the center of the Earth?  (Hint:  it isn’t the top of Mt. Everest.)  After a big earthquake the earth “rings like a bell”.  What does that mean, and how do we know it?  Is the rotation rate of the Earth changing?  Why do most coasts have two high tides a day, when the Moon can only be above them one a day ?  What is that crazy figure 8 that we see on old globes, and what does it tell us?

Otto Muller is Professor Emeritus of Geology
