Answer to:
What shape is the universe? "Closed universes are also closed in time: they eventually stop expanding, then contract in a "Big Crunch."" I don't believe this is true. The universe could be spatially bounded (bounded in the ambient space) and temporally unbounded. The cosmological constants could be such that the quantity (rate of expansion)-(rate of contraction) tends to zero, or the radius of...

What is a good way to start an essay about entertainment? Get some paper, find a relaxing environment, and just write what ever pops into your head for a about an hour or so. Then think about entertainment, and write whatever pops into your head - doesn't have to be any good, and don't stop to correct spelling or grammar, you can do that later. This is called free-writing. It is great for starting a paper. This should be started as soon...

Answer to:

Answer to:
What are some strategies to make studying fun? Unfortunately, studying something that you don't care about just isn't fun. Unless you can somehow convince yourself that you _are_ interested in the subject at hand, the best you can do is try to make it less painful. Study the material that will be presented in class before, not after, the class, and begin any homework the day it is assigned, not one or two days before it is due....

Answer to:
Why is the lemniscate or mobius strip symbol used to represent infinity? The precise origins of the infinity symbol [infty] are unclear. One possibility is suggested by the name it is sometimes called — the lemniscate, from the Latin lemniscus, meaning "ribbon". One can imagine walking forever along a simple loop formed from a ribbon. A popular explanation is that the infinity symbol is derived from the shape of a Möbius strip. Again, one can imagine...

Answer to:
What would a black hole look like from behind? The same as it looks from the "front." I would rather say that "front" and "back" are not applicable to a black hole. A black hole probably appears as a solid black circle from any direction. I think that blaylock makes the same point. Edit, for those of you who want clarification: My understanding of cosmology leads me to believe that a black hole looks the...

Is there any software that will allow a PC to play game discs made for Nintendo, X Box or Playstation? PCSX2 is such an emulator (only for ps2). I don't remember where I downloaded it from, but I have files called pcsx2_07.zip and pcsx2SSE2-0.8.1.7z in my installers folder (I seem to have two versions of it). You might try googling those names. (edit: and leave off the file extensions when you search) You can get a torrent file for pcsx2SSE2-0.8.1.7z here: ...

Answer to:
Who is the smartest man on earth? Somewhat off-topic: James Sidis' parents were the smartest people on earth. The environment they created for him allowed his prodigiousness. I, like most of you, spent a great deal of my childhood in a public school classroom. This is a place where the math taught must be accesible to the student with the least aptitude, the music training catered to the student with the least musical...

Answer to:
Why does the government have to create money? To answer why, take this: "Governments haven't always created their own money: in the past, and in some poorer countries today, banks would issue private currencies, backed by their gold reserves. In modern countries, the government issues money, usually through a central bank, to be able to control inflation and interest rates." And add: the principle purpose of government...

Answer to:
If I rode a hot air balloon and held a flag in my hand, what direction would the flag blow? It would move in the direction of the _local_ wind. The balloon is moving at about the speed of the wind (probably just a little slower), but there will be small gusts and eddies. So while the wind might be strong, the entire flag is moving with the wind, so the fabric part will not be held aloft, barring any small gusts.

Answer to:
According to the Scientific Method, why is the average of three trials in an experiment more accurate than only doing it once? One of the main tools of scientific investigation is induction. So one way to answer your question is that one sample doth not inductive evidence make, and three aren't terribly good, but they are a lot better than one. In my opinion, one sample is largely useless. Another way is this. You collect several data points so that you might predict other data points, i.e. you might want to...

Answer to:
It seems like icicles lean from the edge of the roof inward toward the wall of the house. Is this true? If so, why? Since the side (of the icicle) near the building is warmer and (probably) less windy, perhaps moisture collects there, mostly, and therefore ice forms there, mostly.

Answer to:
When proving a theorem, like Fermat's Last Theorem, how do you know your answer is correct? I must disagree (in part) with Quirkie: It is not the case that "the result was correct because no one else can find a flaw in the steps of the proof," a proof is taken to be valid when it is found that each and every step taken or rule invoked is accepted as valid. Mathematics deals with ideal situations, with abstraction, and so it is not sufficient that no flaws are found, but...

Answer to:
Why are beef burgers referred to as 'hamburgers'? Almost the same reason that hotdogs are called frankfurters. Why they're called hotdogs is beyond me. Also, the "hamburger" we are familiar with did not originate in Hamburg. What came from Hamburg was 'Hamburg Steak' or 'Steak in the Hamburg Style,' which was simply ground beef cooked in patties (this didn't actually originate in Germany, but Hamburg...

Answer to:
Is there a method to calculate the number of possible combinations in a selection from a group containing repeats? This might be helpful: To count the number of ways to put n objects into two groups of size x and size y where x+y=n: n!/(x!*y!) = number of combinations. aka (n choose x). or (n choose y) for that matter. This useful when you want to choose a group of x items from n items because the others necessarily fall into a second group, the group you want to ignore - the y group. For some...

Answer to:
Why is being overweight such a calamity in modern-day American society? "It has something to do with 1000's and 1000's of years of human survival. Our ancient ancestors couldn't have survive in primative conditions with that much ASS-cess. (Blood pressure and diabetic meds weren't invented back then.)" This is absolutely false and absurd. Fat is stored energy. A fat person is fat partly because their body is saving up for the next...

What is "phi"? Perhaps the asker wanted to know about the greek letter phi? If so, one common way of writing it is an "o" with a vertical line through it.

This may be...

Answer to:
If the world's supply of oil suddenly disappeared, how would we be affected? IntellectualCritic is right, except our dependence runs far deeper. Petroleum is used to make almost everything, especially plastics. How about never buying things in plastic bottles again? It'll be too expensive. You'll pay $4 for the milk and $8 dollars for the bottle. How about electronics? Cars and synthetic fabrics too. Adjustments will be made, new technologies will...

Answer to:
How would science prove the existence of God? The practice of science is a way of describing the world around us. The practice of religion is a way of explaining the world around us. And, the way I see it, the tools of science can aid one very little in the practice of religion; logic, however, is very useful in both endeavors. One poster cites the complexity of life as proof of god's existence, which is in no way a scientific...

Answer to:
In Pulp Fiction, is it true that the case owned by Mr. Wallace contained gold needed to buy back his soul from the devil? Isn't it obvious? The events in Pulp Fiction are an early iteration of the matrix. Vincent and Jules are agents - dodge bullets. Butch is the one - badass with a katana. Marsellas is a strange kind of mix between Morpheus and the Architect. et cetera. The case contains the key to zion. I realize that Pulp Fiction was created long before the Matrix, but it's still a neat idea.
