I have BS degree in the field of metallurgy from IUST university of IRAN and i want to continue my study in abroad. I want to know about the condition of other university for giving scholarship for MS degree, specially in the countries that are very good in my field such as canada and australia.

Is there a specific enzyme that degrades testosterone or does the body just depend on the normal half-life and expulsion of testosterone to eliminate it from the body?

Me and a friend saw one a couple of weeks ago. We were looking at the stars, when the stars I was seeing disappeared behind a large black triangle shaped object with faint white lights that did not blink on each corner. It was large, but made no noise. It slowly moved across the north central Washington night sky.

I for one am leaning more towards the idea that it was a test flight of a stealth bomber, but then again who knows.

Has anybody else seen anything like this? or have anymore info on black triangle ufo's?

I found this picture online and it's almost exactly what we saw that night

Every day at night I always look up into the stars and wonderif its possible to have a space station with artificial Atmosphere so there could be rain and snow and droughts just like earth? After pondering it for a couple of days i started to believe that it definitly could happen. I happened to watch Gundam Seed with the naturals and coordinators bc. they lived in the artificial atmosphere stations. After years of battling(cartoons are signs of future progress) if our military increased its production could it happen. But then the Saiyens had their planet destroyed along with Naruto who lives on a new world then ours. is there a way? In conclusion I feel that Canadians are simply retarded and lazy!!!!

According to a story featured on Yahoo today, "Scientists now estimate the universe to be about 13.7 billion years old (a figure that has seemed firm since 2003, based on measurements of radiation leftover from the Big Bang) and about 156 billion light-years wide. The new finding implies that the universe is instead about 15.8 billion years old and about 180 billion light-years wide."

Surely the decimal point in this story is in the wrong place. How could the universe be more than 10 times as wide (in light years) as the age of the universe? Either they have the decimal point in the wrong place or the stars are travelling away from each other through space several times faster than the speed of light.

With all modern technical help in class today, would you still be able to calculate the square root, or maybe even the 3rd, if you only had a piece of blanc paper and a pencil?

I've heard three different explainations.....

1. Time and space areintertwined to make the Space-Time continuum. The faster you go, the slower time moves. (I think this is B-S.)

2. Everythin must be measured relative to something else. If you're doing 40 MPH in a car, you're actually going faster because the planet you're on is rotating.... so you're going as fast as the planet is rotating + 40MPH. (I guess this makes sense...)

3. It takes a certain amount of energy to move a certain amount of matter at a certain rate of speed. (This looks right, but it sounds totally dofferent that everything else...)

4. Green Nuclear Zoom Zooms!!!! Weeeeeeeeee!!!!!!

Is it one of these, or something completely different??

Huge volumes of gas and oil have been extracted from the earth and i assume replaced with water from the sea. Therefore in the knowledge that we have global warming which is melting the ice caps . should this not compensate for the excess water due to global warming?

Combining e, π, i, 1, and 0 (arguably the five most important numbers in math) into one equation is elegant. Combining factorials and powers into infinite sums via a Taylor series to evaluate e or values of trig functions is amazing. Both of these circumstances bring a connectivity to mathematics that is beautiful to behold.

To me, one of the most beautiful things in math is that when the parabola is rolled along its curvature, the path of the parabola's focus creates a catenary... a link connecting quadratic equations to hyperbolic functions.

This is a personal opinion question... what in mathematics is beautiful to you?

A - there are more water molecules than salt molecules in the ocean.
B - only water vapor molecules, and not salt molecules, evaporate.
C - the salt dissolves and forms a solution, which becomes more and more dilute untill all the water is fresh.
D - the salt dissolves in the air.

Indeed. A black hole is just a collapsed star, compressed to the point that it's gravitational pull is astronomically more powerful that the gravitational pull of a regular star (Keep in mind that a regular star's gravitational pull is strong enough to hold planits in orbit of it for billions if not trillions of years.... AND strong enough to pull comets from the middle of nowhere into it's orbit) which is no small amoung of force.

Why do so many people let others fill their head with drivel. How can anyone even be sure of the existence of black holes? Did they see one from a telescope? Oh, please. I once saw an equasion that illegedly explained how powerful a Black Hole's gravitational pull was. I sure would like to know how they came up with this wonderful theory, since they've never even seen a damned black hole.

Whenever anyone asks me where I think people go if they enter a black hole, I always say, "Well, I guess that all depends on what kind of life they led beforehand!!"
