December 21st is the shortest day up here, and in the southern hemisphere it is the longest day. I'd like to hear from you folks way up north or way down south. Give a description of the weather today too, to make it more interesting. Thanks. Here in Fort Collins, Colorado, in the United States, today was about 8 and a half hours of daylight, clear and cold, about 30 degrees or so. Snow on the ground, a very nice day because of the sun on the snow. Take care, and thanks for checking in.

I remember reading somewhere about a diagram that had two overlapping circles such that the area of the intersection of the two circles was equal to that of the the non-intersecting part of each circle. Any idea what this is called, where I can find out about it?

How would one go about removing the ugly white salt stains from soft leather shoes? I recently made the mistake of wearing a pair of high-end soft leather sneakers outside after it had recently snowed and now I have salt stains on the sides of the sneakers. The sneakers are made entirely of leather (except for the soles and inner lining) and the leather is not shiny like on formal shoes but more natural like on a leather jacket (not as flimsy). Not really being a leather expert, I don’t know if I am making much sense with the description and for that I apologize. Any help would be appreciated.

Write in Logarithmic form.
1) 3^4=81
2) (1/2)^4 = 1/16

Write in exponential form.
3) log(4)32=x
4) log(10)0.01= -2
5) log(a)a=1

(The numbers/letters in parenthesis are like littler, do you know, it kinda looks like exponents, but down, not on top :S) thanks!

It is a Celestron Powerseeker 114EQ Newtonian. I cant see any detail on planets. I cant even see them as clear cut discs. I cant be looking at the wrong places as where I am looking lines up with my star maps . The telescope is 4.5 inch by the way. I have tried mags up to 350x with no luck. Is it possible that the collimation could be out. I can get perfect views of the moon but that doesnt prove anything.

a. 4.5 ft.
b. 3.2 ft.

I was watching a programme called universe and to my amazement, there are more stars out there than grains of sand on all the beaches in the world. Do you think the odds on finding life out there is quite high?

I am thinking of applying for a Physics class as I find some of the things people have told me about physics to be really interesting. The problem is that I'm not very good at mental arithmetic and math was not my strongest subject. How important is mental arithmetic and maths ability when studying physics?

Eliminate the parameter t

x = 1 - 4cos(t) , y = -5 + 6sin(t)

I know that the answer is (x-1)^2 / 16 + (y+5)^2 / 36 = 1, but I don't know how or why that's the answer.
