Notes for March 18th

• Useful link if you have questions about...well...how the world works.  For instance, Why is the sky blue?
• Some interesting info on Jupiter's Great Red Spot.  
• I like to say that if an organism isn't aquatic, then it isn't interesting, and that birds are boring.  However, this is kind of interesting:  Are bird brains bigger or smaller when the birds must migrate?
• On the origin of animals.
