4/02 Change to Schedule In our original schedule, WED 4/21 was a day "Held in Reserve;" this was in case of unexpected events which might have occurred during our virtual semester. It looks like we may be able to avoid such events, so I have decided to use this available class to spend a second day on Topic 23 (mostly about Orbits and Conservation Principles). The altered schedule is now available on our class webpage, and the changes are now reflected in our HW due dates at MP. You will now be asked to reread the reading for Topic 23, and you will get a second chance to answer the questions for RQ23. Thanks much, GBA. 1/04 No Updates Yet
