In the Wikipedia entry "matter", matter is defined as everything that is composed of elementary fermions. It is also stated that matter is composed predominantly of atoms.
What else is it composed of?
Portions of atoms which do not form complete atoms?
Thank you.

There's still some disagreement over which desk should get computer problems, so I'm going to go with this one and hope no one minds. I had a great snippet of Java code (I found it on the Internet somewhere) that could take bitmaps in, convert them to two-dimensional arrays, change the numbers however I wanted, and save the result to a bitmap. Unfortunately, the hard drive it was on died and I don't remember the details. Does anyone know how that works? Black Carrot 02:00, 15 June 2006 (UTC)
FileInputStream
(or some other type of input stream) and read first the image size. Allocate the appropriate arrays, then read the image data into the arrays. Obviously you can do whatever you want with the arrays, and it's just as easy to write them back into a file with the appropriate header information. I've done exactly this, although (as it happens) with
C++ instead of
Java. Or were you asking for help in finding or reconstructing this code? --

It isn't working. It keeps throwing up an exception, claiming that the width and height of the image are -1. Black Carrot 22:40, 19 June 2006 (UTC)
(I asked this on the talk page of the corresponding article, thought maybe I would try here as well) As far as I know there are no fireflies in warm dry areas (like on the west coast of the united states). Is this because fireflies prefer more humid climates or is temperature a factor? Would it make sense for an insect to overwinter in a warmer climate at all? -- 69.249.30.109 02:21, 15 June 2006 (UTC)
when a person has fever why is the taste bitter? 67.150.4.232 03:09, 15 June 2006 (UTC)
Which taste? Water will taste tasty if the fever is accompianied by a stuffed-up nose because the scent of the mucus will make the water taste like snot. If you mean the taste of the saliva in the mouth, I don't know, it never seemed bitter to me. Emmett5 03:35, 15 June 2006 (UTC)
Can anyone recommend a (relatively reliable) free online IQ test? If I'm looking to take the test for real, I'd like to have some indication on how well I'm likely to do, and though I've taken a bunch of them for kicks (such as [1] and a few of the ones on [2]) and the scores have been relatively consistant, since none of them are real and most of them are quite short, I can't be really sure if the scores I'm getting are realistic at all! Is there anything out there with a little bit more authority? freshofftheufo ΓΛĿЌ 04:12, 15 June 2006 (UTC)
Carbon dioxide gas and water vapor both absorb IR radiation. Do they also absorb visible radiation?
I would like to know something about what subjects and areas are invloved in Marine and Ship designing. If possible, would like to have some website links which explain the various concepts involved in it.
Let's assume there's a nuclear free-for-all in the northern hemisphere. China vs. USA vs. Russia vs. France vs. Britian... Israel vs. the rest of the middle East... India vs. Pakistan... basically every nuke that could fly, does.
Would this wipe out all life on the planet, or would the southern hemisphere be largely unaffected (apart from the massive economic collapse caused by losing the northern hemisphere)?
And speaking of which, would life up there be COMPLETELY gone? Because according to Threads, some people would survive, they'd just be living in an incredibly bleak and pointless world.

According to Einstein’s general and special theories of relativity, this states that the speed of light cannot change.
However I am confused by this: The way I have always understood the theories of relativity is that time slows down to keep the speed of light constant relative to your own velocity. However if this is the case then moving at any speed will cause the speed of light to change relative to you, for example, the speed of light is moving at 2.998e10^8 but if we are moving at a velocity of 30 ms^-1 then the speed of light traveling towards you would be: 2.998e10^8ms^-1 + 30ms^-1. I knew that the speed of light could never change so I therefore thought that time would slow down to keep the speed of light constant but if this is the case then time would slow down to the point at which you would not move, because if you move at any speed then c, would change relative to you??

1) When light passes through matter, like glass, it slows down, so the speed of light CAN change, irrespecive of relativistic effects. 2) When the velicity of an object increases, so does it's mass, this has the effect of slowing down observations, and this slowing is not noticed. This is because the reactions act more slowly on massive objects.- 12.10.127.58 ( talk · contribs) 20:12, 15 June 2006
Regardless, light and sound have so little in common that all but the most basic of analogues are misguided. Skip that. The problem with your question is that the speeds you reference are in units of distance AND time. Change the rate of time, and the numbers will have to change. It is hard to grasp without much study, but just trust Einstein when he says that you will never catch light in a vacuum going any speed besides C.
There's nothing in relativity that says the speed of light can't change. A popular idea in cosmology is that fundamental constants like the speed of light may be changing, though very slowly. The weak anthropic principle is the idea that the constants of nature vary from place to place in the universe, and we exist where we do BECAUSE the physical constants in this area are favorable for our type of life. Nifty, eh?
And to the orignal asker of the question, I would strongly recommend a special relativity course; it's the best way to understand this stuff. And it will blow your mind! Wheeeeee -- Bmk 04:41, 17 June 2006 (UTC)
hi, i was told by my primary school teacher that if you cut a normal, garden worm in half, the two halves will grow back into two new, fully functioning worms. my question is, is there a finite amount of times you can cut up a worm for this still to be true? if i cut a 10cm worm into 100, 1mm pieces, would i get 100 new worms or would the 100 pieces be too small to regrow and hence die? thanks! 87.194.20.253 19:49, 15 June 2006 (UTC)
Whats the best diet/excercise for maximum muscle build and fat loss in the shortest length of time (ie a few weeks) even if you can spend everyday working solidly. I was thinking maybe anaerobic excercises, but I dunno. And also what are some examples of them as I don't know any anaerobic excercises, if that is the right answer. Thanks dudes.

I just baked a salmon before scaling it. So after cooking there is a thick section of pink coloured meat, on top of which is a thin layer of brown/pink meat which is easily scraped off seperate from the pink meat. On top of the brown/pink meat was the scales. The question is: What is that brown stuff? And more importantly: should I eat it? Thanks --Tacobake
Hello. I am running Windows XP and I am having a desktop problem. There appears to be unwanted shadows behind the incons on my desktop (but here only). If the color of the background is white, and the color of the desktop is (right clicking the Desktop > Appearnce > Advanced), say, black, then the shawdows behind the icons on the desktop are black. The problem is that there is no option to not select "blank". When I create a new account on the computer, the solution is solve; but I don't want to keep two accounts. Do you know what the problem is? I can supply a picture if you want to email me, but I don't want to upload it to Wikipedia to illustrate a point when it won't be used in any articles. Thanks a lot.

The earthworm question above have prompted me to ask this question: Why do lobsters (and other crustaceans) not die when they are dismembered, halved, or removed from water? How do they die in a pot: do they simply cook from the outside-in until there is not enough living flesh to sustain its life? Do they feel pain? -- Chris 22:01, 15 June 2006 (UTC)

Following on from the 'nuclear apocalypse' thread, I find myself wondering about humans literally causing 'the end of the world'. While we are certainly capable of causing the extinction of our own (and other) species, be it via nuclear war, a manmade virus, poisoning the air and seas, destruction of the ozone layer, etc. - is there anything that humans could do/cause that would literally 'destroy the world' (i.e. result in the complete anihilation of the Earth)? I can't think of anything offhand - even if all the nuclear weapons in the world were set off in a huge global pissing war, the net result to the planet would only be a few craters and scorch marks on the surface, right? Would I be right in thinking that the only kind of event capable of destroying the planet itself would be one of extraterrestrial origin (e.g. a gigantic asteroid/planetoid collison, the expansion of the sun into as red giant, etc.)? -- Kurt Shaped Box 23:16, 15 June 2006 (UTC)
