Sorry about that. I could have sworn I typed 'volume' but for some reason it came out 'area.' Fixed now.

Find the volume of the solid generated by revolving the region bounded by y = x2, y = 2-x2, and x = 0 about the y-axis. I'm taking Calc I and this question was on a test I took yesterday. A couple things about it didn't make much sense, which suggests to me that I'm missing something. I...

OMG OMG OMG OMG OMG OMG OMG *takes a deep breath* OMG OMG OMG OMG OMG! *wipes away a tear* This is truly amazing. I've been waiting to see this in the news for years now.

I never lie. I do, however, always tell the truth.

I don't know how related my sentiments are to yours, but I often feel extremely ashamed to be a member of the human species. With few exceptions, the people I have met in my life can be described as overgrown children, wrapped in their own insecurities and protected from growth and meaningful...

I was browsing over my physics course work before going to bed, getting ready to take my midterm exam tomorrow, when it suddenly dawned on me: The universe exists. [SIZE="6"]o.o Holy ****! Wow. How ****ing crazy is that? I mean, yeah, all this time I've been deriving equations, trying...

Extremely fascinating. Well worth watching. I find it very interesting that the apes, when presented with the transparent puzzle box, ignored the instructions and just went straight for the candy, while the children continued to follow instructions. At first glance, the apes' approach...

Yeah that's correct. It goes along the same lines as getting the liar to lie about lying. Although, it would potentially fail if the two guards didn't have knowledge of the other (the truth guard doesn't know the other always lies and the lie guard doesn't know the other always tells the...

Sorry, but that's absurd. In a potentially extremely different environment with conditions much unlike those on earth, different elemental composition, different selective pressures, a different geological history, potentially different genetic codings for different proteins that may function...

I've heard this before but I've never seen the solution or worked out the answer. At first glance, it seems to be unsolvable, as you need two pieces of information. You must determine which door is the one that leads to freedom and which guard is which, but either guard you ask has a 50% chance...

I'm not sure if it'll help any, but this is a brief insight into my philosophy: I find projecting human feelings and emotions onto creatures a bit silly, but at the same time I cannot bear to see any organism suffer that is capable of suffering. I will go out of my way to avoid causing said...

My apologies, it seemed to me that you were overlooking the fact that they can't replicate without infecting the cells. But no, they'd pose no threat for that very reason. Additionally, one reason viruses aren't considered life is because they do not metabolize, and therefore do not require even...

If the first two have the same colored hats, the third instantly knows the color of his hat is not that color. If not, the second would be the only one to have certainty of knowledge of the color of his hat, because if the third person says nothing, this means that the colors must be different...

To even 'recognize' a target cell as a potential host, the virus must have a protein shell that can interact with the proteins and receptors on a particular cell's surface. Even if extraterrestrial viruses somehow developed a mutation that allowed it to invade some cells on Earth (which couldn't...

Just wanted to point out that panspermia/exogenesis does not require that life have a single origin, just proposes the idea that life can be 'seeded' on a planet capable of supporting life (or that it was seeded on earth) from another source, such as comets, or debris from a large object...
