[Chaos-l] Astronomy 161 and 162 Lectures (free)

[Mark South]

Hi,
I wanted to pass along a link to some amazing free lectures and notes  
that are pod-casted from Ohio State University.   If you have iTunes  
or any podcasting software you should be able to subscribe to these  
lectures for free.

Dr. Pogge is thorough and interesting.  3 basic questions he tackles  
throughout:  1) What is it? 2) How does it work? 3) How does it  
change over time? He also ties in history of astronomy so that you  
learn the subject in it's historical development.  This is a great  
approach because it helps strip away all the technology and forces us  
to truly observe without telescopes at the naked-eye phenomena.   For  
example, at MASP we noted that Mars rose after midnight and Venus is  
high in the sky an hour before sunrise.  Jupiter is setting with the  
sun.  The moon today is at a think crescent.  Based on these  
observations you will be able to see where each of these planets are  
in their orbits relative to the earth without even a 1 calculation.

I've learned so much from listening to these lectures going to and  
from work.   I know of one other group member who is also listening  
to lectures and will attest to how good they are.

We believe that this will help us 1)  to enjoy our own observing more  
and 2) teaching others at public sessions.

The supplemental text is "21st century astronomy" and this is a great  
learning tool as well.
