Assignment #1

2000 January 19

Reading Assignment

Sproul, Primal Myths. Please read the following African creation myths before class on Friday: The Supreme Being, God Retreats to the Sky, Making the World and Man, How Zambe Created Man, The Quarrelsomeness of Man, When God Came to Earth, The First Words, The Creation, The Separation of God from Man, and The Great Gods.

Journal Assignment

Due: Friday, 1/21 at the beginning of class.
Briefly discuss the different ways in which man and the deities are related to Nature in the above myths (just state a few of the essential, general ideas; I'm not looking for a long essay). Which myth do you find most compelling or intriguing, and why?

Observing session (optional): LUNAR ECLIPSE

Our course is beginning with a celestial bang: an eclipse of the moon! This will occur tomorrow evening (that's Thursday, January 20). Provided that it is not completely overcast (the forecast looks dismal), please come to the roof of Campbell Hall (between LeConte and the Mining Circle), where we will be able to examine the darkened moon through a large telescope. The door of the building is likely to be locked, but wait downstairs for a few minutes and someone will come down to let you in. Take the elevator to the 6th floor, then the stairs to the 7th. Below is the schedule of events (all times are PST). I would suggest showing up at some time around 7 pm. If it's cloudy, there will be another chance to see a lunar eclipse on July 16, and watch for the solar eclipse on Christmas day this year!

6:03 pm Moon first enters the penumbra (the light part of Earth's shadow); nearly imperceptible.
7:01 pm Moon begins to enter the umbra (the dark part of the shadow); eclipse becomes noticeable.
8:05 pm Beginning of totality. The moon is completely engulfed in the umbra.
9:22 pm End of totality. The moon begins to emerge from the umbra.
10:25 pm Moon leaves the umbra completely. End of the easily visible part of the eclipse.

To impress the natives, Christopher Columbus orders the darkening of the moon (February 29, 1504).
