I'm looking in the sky this morning and I see a very bright, what appears to be a large object. It's not moving and is to the East - Southeast. I'm in Arizona and it was at 545am on Nov. 17,2007. Is it a planet? Satelite?

When I mix these two in solution a precipitate forms at the bottom. It is a waxy substance with a seemingly higher concentration of lavender oil than the castile soap normally has. My hypothesis is that the epsom salt is dissolving the water soluble parts of the soap into the solution and leaving behind the lipophilic and phenolic compounds in the soap.

I have now fully understood the kelpers first law.
I now trying to learn kelpers second law.
i have seen that it states : A line joining a planet and the sun sweeps out equal areas during equal intervals of time as the planet travels along its orbit or in other words each "wedge" has the same surface area.
Does this mean that planets dont travel at the same constant velocity along their orbit?
What about a satellite in GEO orbit travelling in a circuler orbit, does it travel in constant velocity(speed) through out in its orbit?
another thing which is the correct spelling is it KELPER or KEPLER
Thanks alot in advance.

the procedure to my experiment is:
-2 grams of PREVIOUSLY HEATED CuO and a corn-grain amount of sugar were grinded in a mortar.
-The mixture was transferred in a test tube and covered with a rubber stopper with bent glass tubing.
-The test tube was attached to an iron stand in an inclined position, and the other end of the glass tubing was immersed in 5ml Lime water.
-The test tube with the grinded mixture was heated with a bunsen burner.

A doctor told my girlfriend that she needed more vitamins and so I did some research and apparently vitamins are electrolytes. Anyway so I bought her a lot of gatoraide because I saw on tv that it has a lot of electrolytes and makes you really fast at sports. But she's getting sicker now and is slower at everything! I'm not sure why she's so slow at sports now because she used to be fast and electrolytes make you faster too right? So maybe the doctor is a quack and something else is wrong. Someone else told us that vitamins are like goosebumps but I have no idea what that means.

True or false:

An integer prime p can be written as the sum of two squares if and only if there exists an integer n such that n^2 is congruent to -1 (modulo p).

Prove your answer in a fairly elementary way.

I've come across a lot of people talking about alternate theories to plate tectonics recently and the most outrageous and well-constructed one is the expanding earth theory. One such proponent is Neal Adams. He has a video on youtube: http://www.youtube.com/watch?v=VjgidAICoQI
What concrete arguments are there against his theory? He's a tough nut to crack.
