Science & Mathematics - 31 December 2006

I remember looking at my chemistry textbooks and seeing the orbitals fashioned as something similar to an inflated balloon, but do the electrons travel solely on the surface of the balloon or both on the surface AND into it (as if the surface were the farthest they could reach)?

hope I didn't totally screw up the question I had in mind.

I was looking at my pet rabbit lying around on its side...full of fur. Then the question came to mind. Do all animals have bellybuttons? I mean, humans have them...do animals like dogs, cats, rabbits have them? They all had an umbilical cord in their mothers womb...so I was assuming so. Is it that they are so full of fur that we can't see it?

i'm an architecture student. i have a problem in DESIGN which is one of my major subject.. i don't know if i should quit architecture, since architecture requires a creative mind in designing things.... and because of that, i don't attend my class in DESIGN regularly.. It's just that i don't know how to design specific things given to us by our professor.. i don't know what to do.. but i'm enjoying most of my subject especially graphics and visuals.. but DESIGN.. i don't know,.. when i attend my class in DESIGN,.. i feel like i'm stupid 'cause everybody is busy doing their stuff, and me..

Could someone please explain to me in great detail how to solve the following using cramers rule?

1. 5x + 7y = -3
2x + 3y = -1

2. 5x - 2y = 4
3x + y = 6

3. 2x -y + 3z = 9
x + 2z = 3
3x + 2y + z = 10

4. 3x - 2y = 1
4x + 3y =2

5. 2x + 3y = 7
8x + 12y = 2

Thank You!!

The fossil fuels we r gettin now is known to all that they r non-renewable sources of energy, but how's that! i mean, these fuels r obtained by decomposition of the dead organisms of pre-historic ages, but what happened to the organisms that died after those times? Won't they form fossil fuels? That means, even these fuels r renewable sources since the organisms which dies now might get converted to fuel later!!! plz some one xplain this if i'm wrong!!!

What are your views, opinions? Is it contradictory to try to prove that which is based on faith? Or not? What are your views on science in general, as opposed to religion? Please think out your posts and try for grammatical accuracy; anything I can't readily read or understand will be disregarded.

Using a simplistic rule from pre-algebra, i came up with a question. If you divide a positive number by a negative number, or vice-versa, you geta negative number as the answer. If infinity (positive) divides itself by negative infinity, won't it egual negative infinity?

I know in industrial engineering you work in business and analyze products and their efficiency, but that sounds kinda boring. Is there anyway that this can be used in the entertainment industry. Music, television, event coordinating??? I just want to know an exciting field of industrial engineering.

In old paintings from the 1500's there are supposedly UFO's in the background. This was way before the concept of UFO's was made. Even more amazing there have been markings on cave walls that look like UFO's. Could they have come?
