I was planning on going to the zoo tomorrow, but I was wondering if animals would be out. The weather tomorrow is supposed to be between 45 and 50 degrees with no rain and sunshine. It has been raining here for the past few days. Thanks!

shouldn't the distance of the image depend on the distance of the object? (1/f= 1/di + 1/do) so why does the light focus at one point, and not even a focal plane since all light entering the eye isnt parallel to the principle axis.

do they? No referals to other sites please.
I couldn't give a damn, much, although I have an opinion; I'm a spectator,but it looked like magic to me that they fell at freefall speed, no energy being diverted to other observed phenomena such as portions of the building going "up" as well as down.
There's a Noble prize waiting for someone who can explain this phenomenon, it's not in my gift, but I would lobby to nominate a sustainable hypothesis, and sure as hell you'd get it if you could explain. And a congressional medal probably.
ps. equal and opposites in free space considering gravity is something ruled out by my sixth graders.

One means, two means, one proportion, two proportions, multiple proportions. Confidence Intervals and Test of Significance. Thanks for the help!
