When a dead person visits you in your dream when 1. you haven't been thinking of them at all during the day and 2. you haven't been thinking of them at night what does it mean? Sylvia Browne says it really is them, but I think she's a scam. Is it really them or?

Galaxies and hurricanes. They have an extremely similar shape. I suppose this has alot to do with gravity. But it is interesting nevertheless. You you ever thought of this: Our solar system is like a giant atomic system? so mabe in a way we are just a tiny atom in a much larger element? It seems that most things in the universe are either circular or spiral in shape. And the same can be said if you look at an atom under a microscope. Its like a huge chain. Starts out small and continues to get unknowingly huge!

I Have Been Doing Some Research On The North Star(Polaris) And I Have Been Told That It Move But VERY Little...Is This True???I Have Been Told This Many Times. Is It Or Is It Not???
Personally I Believe That It Does move VERY Little...Heres My Source For My Thinking-
http://www.coldwater.k12.mi.us/lms/planetarium/myth/polaris.html
To our eyes, Polaris appears to be motionless at the center of the field of circumpolar stars. All the other stars appear to circle about Polaris. As early as 320 B.C. the Greeks had realized that Polaris did not mark the pole exactly. Until then many people had believed that the heavenly pole was absolutely and eternally fixed. Not so. Polaris has long been moving nearer the North Celestial Pole, as it is still doing now. It will be closest to that position around A.D. 2105--27'. Currently it is about 1° from the celestial pole.

Does Anyonw Have Anything Against This Sight That I Should Know About!!

If the rate of growth of cancer is modeled by: N'(t)=Ae^kt ; where A=rate at time= 0 days and K=a constant:
a) Suppose A=50 and at t=5 days, the cells are growing at a rate of 250 cells per day; find a formula for the number of cells after t days given that 300 cells are present at the beginning of this study.

b) Use this formula to calculate the number of cells that should be present after 12 days.
