I am thinking about buying a Newtonian Reflector telescope, it is a short tube with a focal length of 1400 mm with a moon filter and a sun filter. Does anyone have this telescope or know anything about this? I would like to know if this is a reliable scope or not.

We all know that all mind plays tricks on us, esp. when in the sun for hours, baked by the heat. I don't know about this one. (Not sure on what science category.)

What would be your reaction? Would that change the way you view life, would you feel you are in existence now?

Plus, do you believe the myth about the pot of gold and leprechauns. I love rainbows and actually seen a few-but don't believe the myth. (Not sure what science category this goes into.)

I've noticed this question has been twice asked before, so I put a spin on it with any season. I love sunrises and sunsets in any season. They're really pretty. I have Lake Erie has a backyard for where I live in Euclid Ohio. It's breathtaking. I take photos and write poetry on it. (I'm not sure what science category this fits into.)

I mean proportionally. I know that blue whales and such have big brains, because they're so big. I'm talking about in relation to the animal's body. Which has the biggest, proportionally?

I'm trying to solve this partial fraction integral, int:10/((x-1)(x^2 +9)) dx
I wrote that A/(x-1) + (Bx+C)/(x^2+9)= 10/((x-1)(x^2 +9))
I multiplied across the equation by (x-1)(x^2+9) and got
A(x^2 +9) + (Bx+C)(x-1) = 10 Then I multiplied the left side of the equation out and got..
Ax^2 +9A + Bx^2 -Bx + Cx -C = 10 Then I set up a system of linear equations like this
A +B = 0
-B +C = 0
9A -C = 10
Now I'm stuck.. I may have made a mistake somewhere, but in any case I'm not sure how to solve this system of linear equations. What should I do?

increased by any percentage? I've heard this is true but I'm not positive. Anyone know anything about this? If males are more prominent along the father's side of the family, does that affect the chance of having a boy?

So I'm cleaning out my garage and a little black spider with a red hour glass on its abdomen says hello to me (from a distance). It had a good number of egg sacks around (white blobs).

I killed the ones I could....question is how do I kill any others and how do I keep them from going in my garage. Is there some "Black Widow - Be Gone"?. My house is less than 6 months old...
