A TV program mentioned an area that looks like a great water
fall but wtih no water.
Scientists thought the area was carved by errosion, but another researcher postulated a glacer melt caused the feathures

Is it weird to be kind of freaked out about why we(people) exist, and where we are in the Universe? I look at pictures of outer space and find myself thinking and pondering sometimes where the hell are we? What is out there? we are on some planet living life. Who are we? are we just some biological stuff? What exists outside of space, outside of all the blackness of space? Is there something greater? Why are we humans, animals that can actually think about this stuff?

I realize no one knows, but anyone know of any good books about this stuff? I hear Cosmos is something about this?

-warning stupid questions-
1. If the reasearch embryo keeps growing up does it turn into a kid?
2. Whats so un- human lifeish about being fertilized in a lab?
3. There was something about, like, skin off a mouse's back that can be made into a mouse embryo... so could the embryo grow up?
4. So... They're reasearching to turn human embryos into, like, livers?
Thanks for reading=)

My friend showed me a homemade accelerometer which consisted of a cork floating at the top of a jar of water. The cork is attached to the bottom of the jar using a length of thread. During sudden movements, the cork moves toward the direction of acceleration which seems to defy Newton's 1st Law of inertia. How does this work?

1) express kx^2 + 2kx + 2k - 3 in the form k(x+a)^2 + f(k).
hence findthe range of valus of k for which kx^2 + 2kx + 2k - 3 is always positive.

We're talking here about the series of optical phenomena that took place in the sky over the U.S. states of Arizona and Nevada, and the Mexican state of Sonora on March 13, 1997.

No, they were NOT flares...flares don't fly in formation.
But, what was it?

Former Arizona Governor Fife Symington witnessed the event and said:
"To my astonishment this apparition appeared; this dramatically large, very distinctive leading edge with some enormous lights was traveling through the Arizona sky."

THE STORY:
http://www.cnn.com/2007/TECH/science/11/09/simington.ufocommentary/index.html

Symington will appear on the Larry King Show tonight to discuss this sighting.

Serious posts only please, something "not of this Earth" was up there...
what was it?
what do YOU think?

Hi,
I'm doing h/w on factorising quadratics and I really can't work out how I'd go about factorising this expression:
p^2 - 8pq + 15q^2
Any ideas (+ explanations)?
Thanks!

If you can apply either the comparison test or limit comparison test then tell wheter it is convergent or divergent, if neither test can be applied to the series than say what test does
summation n=1 to infinity (cos(n)sqrt(n))/(9n+3)
summation n=1 to infinity ((ln(n))^2)/(n+9)
summation n=1 to infinity (9n^5-n^3+6n^(1/2))/(2n^7-n^2+2)
summation n=1 to infinity (9n^6)/(n^9+1)

math and science? When did astronomers start to understand what solar eclipses and lunar eclipses were? How complicated is the math necessary to calculate the movement of planets and future dates of eclipses? Before the computer was invented, how laborious was it to hand calculate those astronomy data? Prior to the invention of the clock and the 24-hour time format, how did astronomers measure time and express time?
