Open Question: Arc units in astronomy???
Does anyone know what "arc units" are in astronomy? I can't find an explanation anywhere.... Edit: I think it's supposed to have something to do with grades, minutes and seconds... But I'm not 100% sure. If so, how does that work?

wat kind of parents do they have? especially wen one McR fan tells he/she doesn't believe in God,it does really strike me. wen they see His big univers?do they have real proofs?if there's no proof to believe in Him,what's the proof not to believe in Him?! if they don't believe in Bible,they can search in other holy books,the great example is Quran(Muslims' holy book) even it was written 1400 yrs ago,but God's talked about everything that a person needs to know to have a good complete life in THIS world and in the next world-->sent to heaven there are many scientific subjects in Quran (we search abt them in school),for example electron,science of germ,astronomy,and ... all the scientific things that scientists have discovered till now,but there are still more more more things to find out,it amy takes centuries,or maybe never. but God has talked abt them in Quran.surely. i promise u if u read it and its explanations and paraphrases,u'll think about it(...) (...)u must search in Quran or any other holy books,how can u be an athesit when you don't know a thing about God's power? i don wanna hurt u or insult u,but guys,be careful,there IS another world,wen we have to answer God's question and give our reasons to be atheists. think about ur beliefes,change them i'm so sorry.pity for McR fans who has a cross shape in their nick anme in Y!A,but say "we don't believe in God,cuz there's no proof!" animals are better than the atheist person by the way,do u know wat "CROSS" is???!!!!what symbol? sexy and whore singers/actors wear a cross necklace ,but they don't even know wat it means!!! all my words: i'm so sorry and scared for ppl who just live and want THIS material world

Open Question: Parabola question! I'd appreciate the help...?
Astronomy : British astronomer William Lassell used a telescope he built himself to discover a moon around Neptune in 1846, two moons around Uranus in 1851 and a moon around Saturn in 1858. The mirror from his telescope has a diameter of about 60cm and a max depth of about 0.36cm. A cross section of the mirror is in the shape of a parabola. a) Suppose the origin of a coordinate grid is placed at the vertex, the y-axis is the axis of symmetry and the units on the axes are centimetres. What are the coordinates of each end of the curve? b) Write an equation of the curve. Thanks so much for the help!

Open Question: Human created things in a nutshell????
It seems that anything made by man EVER, was a scientific achievement, something raw and mathematical, based on something tangible and basically "in front of" man. Except for one.... Since man created the Bible, (Old testament and new) it has to be based on something, something tangible, something already known, something that Man has been able to observe, dissect, and assemble again in order to form a distinct conclusion. The Bible is no more than a metaphorical description REALLY and CLOSELY related to astronomy...(like every other religion ever created because the stars are the closest thing we know as "heavenly".) no? Unfortunately the Bible is not better than Egyptian inscriptions or Greek tablet writings (they have characters related to suns and stars as well). What does the Bible mean to you?(atheist or religious) What do you think the Bible really means? Do you think the stories are real? (characters and all.)

Open Question: To me, this underscores our responsibility to deal more kindly and compassionately with one another?
We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam. The earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity -- in all this vastness -- there is no hint that help will come from elsewhere to save us from ourselves. It is up to us. It's been said that astronomy is a humbling, and I might add, a character-building experience. To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known. http://obs.nineplanets.org/psc/pbd.html

I plan to join the Army (and hopefully be able to make it into SF) after I graduate High School. What I'm asking is, are there any programs that will help me afford college after I put in my time? I really want a PHd in Astronomy, and I actually have the brains for it. So, would I get aid financially? Also, are there any decent paying jobs that you are qualified for after military training? Thank you. Ok thank you all. Yes I do realize how tough SF training is and that I might not make it.

I am good at one thing and one thing only - the lithosphere (one of the 4 major components to geography). Beyond that, everything I am too stupid to do - biology, virology, chemistry, physics, astronomy, reading, chess and practically every game, writing, spelling (I use spell check), math, socializing, exercising, volcanology, geology, seismology, all the arts including martial arts, EVERYTHING! Even in geography, I such horribly at atmospheric sciences, the hydrosphere, the cryosphere, and the biosphere. Even aspects of the lithosphere I suck at like any landscape modified by glaciers. Why is it that my intelligence is so narrow compared to other people? My friend Charles is great at so much more than me.

Resolved Question: Isn't it amazing, the size of the universe!?
I'm 14 and in science, we are learing about astronomy. We watch a video almost everyday. They showed pictures of far, far away galaxies taken by the Hubble Space Telescope. It was so cool! And it makes me feel better too, you know? It's like if I get a big fat zit in the middle of my forehead (lol), it isn't the end of the world! you know!?? I know this is wierd but the size of the universe amazes me. Light travels SO fast, and yet it take 8 mintues for the sun's light to reach us, because we're so far away. And 92 million miles is nothing in comparison to the other galaxies and things we see in space. If someone were to see a star explode (I forget what that's called), it probably happened billions of years ago, but the light had just then reached us. anyways, thanks for reading... :)
