Wine is great. it can be rather slow and doesn't always support advanced things some win32 applications like to do. On the whole it's great. I've even got Morrowind (if you don't know what it is google it) a huge game to work although a bit slowly. just keep wine updated at it should work just fine for you. if your looking for an easy to use distro of linux try SUSE go for the older 9.1 it's free and you get better packages the 10.x only has open source packages which gets rather annoying(no JAVA etc.). there is a pro version of 10.x but last time I checked it was too expensive for my taste.

I would suggest buying from a name brand on laptops. for desktops I strongly suggest people build their own. In today's world to be afraid of the contents of the "mystical box" isn't really an option. most things are easily figured out and everything either fits or not. as long as you dont' force parts in nothing should go wrong. If someone is unsure about it there are many computer geeks around ready to help(I'm one) or there are great tutorials online. For everyone not willing to do this by all means follow those rules they are very very good. PS. a note on operating systems. Windows is generally easy to use but i strongly suggest taking a look at linux there are several commercial and freeware distrobutions that are much easier to use than windows(aka SUSE)

Here is some fun physics. The same problem came about with the idea of black-body radiation. A black body is a perfect absorber of energy and through about five textbooks of physics it also must be a perfect emitter. the setup described at the beginning of this post is very similar to that of what we use to simulate black body radiation.The only change is that the box was evacuated and light was shined in an actual hole in the side of the box. At different temperatures there is different proportions of frequencys emitted. if you could find a perfect mirror you could make light bounce around indefinitely if the box is completely evacuated. Only certain frequencys of light will actually be reflected because a mirror dictates that the light reflected has a 'node' at the surface of the mirror. a node is a place that there is no change is position. in this case the electric and magnetic fields are both zero in a standing wave on a string there is no vertical motion. with a substance in the box there would be dispersion of light and some energy of the light would be lost in colliding with the air molecules which would then heat up the box. this is not good given that you could easily transfer 1000 watts of energy using a good halogen light bulb. another loss would occur as does in high intensity light. In potentially high density photon regions it is possible that two photons could collide (it's been proven they can and do!!) and in doing so would create a particle, most probably a electron or other charged particle. an anti particle would also be created( conservation of charge). the antiparticle would annihilate something in the wall of the box and the electron( or other charged particle) would act as a free radical and destroy compounds in the wall of the box. This occurs quite frequently but it's effect on let's say a spot light is so small that in a thousand years no visible damage would occur. it is quite a different story inside the box. all the damage would occur to a relatively small area (aka: the inside of the box) instead of being able to be spread out over the atmosphere and subject.

While yes there is energy stored in a magnetic field, it's impractical to use in most situations on a large scale. it would be cool but as of yet impractical. A side note. we can store energy in a magnetic field through a type of electrical device called an inductor. it is typically a coil of wire(solenoid) or a torus of wire (toroid) and have all sorts of uses but that gets into some deep physics and i'll refrain from posting that until it is requested.

What we use as colors (red, green Blue) are just labels to the frequency of light we recieve. there are a few disorders that change to color of the lens of the eye. one of my friends was taught the wrong colors as a kid. he still labels things the wrong color. he sees the same light that anyone else would be the labeling is differentanother fun(to talk about) disorder is synaesthesia. it's a cross wiring of the senses. people with this could be seeing smells or tasting colors. it's not common but interesting notheless.

it is because money makes the world go round. college especially are looking for students that they can invest in and get a return. having a winning football team is more important to the funding of the college than a bookworm doing research. in my opinion this is backwards and i'd like to see it changed(being a science geek myself). a researcher who makes a breakthrough could bring in millions to the school but it's too risky. they want a fast turnaround.

quantum mechanics is a little confusing if you've had classical mechanics or know a little classical physics. Take heart classical physics is a limit of quantum mechanics. Quantum mechanics(QM) is a correction to the classical model that accounts for when things get really small and Clasical methods don't work. a great example of this is the "Ultraviolet catastrophe". the setup is like this. you have a box with a small hole in the side and is completely mirrored inside. this simulates a perfect black body. there are only certain wavelengths of light allowable inside the box becase the limit is placed on the light by the box that there must be a node(a place where a standing wave doesn't move). after a lot of calculus the classsical model predicts that for a specific temperature there is a curve that relates the intensity of the light emitted back through the hole to the frequency. the equation is useless because it relates it by frequency squared. this is absolutely wrong. the higher the frequency(gamma,x-rays) the larger the amount radiated. it doesn't work. planck a leader of modern QM through some "lucky Guesswork" derived the equation that fits the observed curve exactly but he didn't know why. it was because the assumption was made that light had fixed quanta of energy. and QM was born. QM is about probabilites. it deals with things that are too small to know exactly where they are. we're talking on the order of ten to the -25th really small amounts. i'd suggest buying a textbook for introductory QM if you are reallly interested in it or search it online. as for the multiple unverses i defer to the ideas and theories forum there is a good discussion of that there

I am a non-traditionalist Hindu. I believe this because it doesn't embody the as actual beings looking down on the Earth but treats them as forces. the underlying belief is that you should be the best person you can and don't need a gift from these higher beings to achieve it. it is also generally accepted that you don't have to believe all of the religion to be a part. it generally is required you read a few holy texts. in my opinion any person wishing to consider themselves Hindu should also know how to meditate.

The other Universe's aren't being created and destroyed. they all exist simultaneously although they are out of our reach and unconnected to the present universe that we see around us. in the 2-d example the other planes still exist just they aren't visible to someone in one of the 2-d universe. by the way another possible 4th dimension(and possibly fifth) would be probability which is possibly a little easier to visualize. each minute movement along that axis would produce a slightly different universe along side our's where things haven't turned out exactly the same.

hey all,I'm a senior at highschool and enjoy all sorts of high voltage things. I've been takin course at a local community college for the four years i've been in highschool and i have 3/4 of a bachelors degree in chemistry. i love classical and industrial music and absolutely hate modern rap(sorry to those of you who like it). i love physics and plan to pursue a doctorate after obtaining a chemistry and physics at the bachelor level. i'm from a really small town so used parts are rampantly abundant. i've already been in a little trouble on the forums but have cleaned up my act (note the warning level).hope to hear what everyone has to saybye

i think that this would be a great idea. Anytime that you can differentiate something between normal and disciplinary it will help reduce confusion. I would suggest making the non-disciplanary version maybe a blue color to differentiate it from the normal test of the post or forum.

By the definition posted by matto it is still possible for there to be another universe. it just takes one postulate to be feasible. that postulate would state: There is an additional dimension to our reality beyond the three that we are free to see and move in.This is already satisfied in our world to date. The fourth dimenson would be time or to go a little further and place the restraint that it had to be another space dimension things will still work out because we would not be able to see or move freely in this fourth dimension. Just move a slight distance along that fourth dimension axis and you are in another three dimensional space and thus another universe although it may be completely empty or infinitely small. since this can be hard to see for four dimensions so i'll give another example in three dimension but it'll involve a move to flatland. let's imagine that we live in 2 dimensions, our flat-universe. then let's place a line perpendicular to the plane at a given point. if you move any amount in the third dimension the point is not in the plane of the universe but there is still a plane there thus there would have to be another flat-universe.

It is most definetly possible the only obstacles to this are our current technology of genetic manipulation and that we don't know where all the genes that control human intelligence are located. There is another theory that somewhere in our genetic code is a lock. it requires data be removed from the extrons of our DNA and adding the genes for intelligence to it. this is based mostly on the fact that the genetic code would be a whole lot more efficient without having to sort tons of junk data. another problem with making the most intelligent being on earth is how do you define intelligence? is it math and science. is it aptitude for music or art? i think our biggest problem once we get the technology is determining what do we want to do with it.

Most of what is considered toxic from landfills isn't organic. most are heavy metal laden compounds such as mercury and cadmium. enzymes wouldn't do much because they typically work on large compounds and typically require a neutral enviroment to work effectively. neither of these are present in landfills. The compounds would have to be treated with some sort of inorganic compound that would make the material insoluble in water and fall out of solution where it could be collected and reused more effectively. another method for reducing toxic leakage in landfills doesn't do anything for the decomposition of the trash. they line each "cell" of garbage with thick heavy non-reactive plastic so that no water can escape or any other liquid for that matter. it is horrible because it deprives the decomposing bacteria of light and water but it does save the toxic leaks caused by inappropriate dumping.

I would suggest that instead of sugar which can be sticky and annoying instead include a syrup type packet. not the maple syrup that you put on pancakes but like the syrup that soda is made out of. it is cheap and doesn't require massive stirring operations to dissolve. I have the same problem when i buy a flavored coffee but they usually add way too much flavoring so i think it could be a good customization to a coffee shop.

I have a few things to add as to identifying black holes in the universe. The black holes that don't spin we cannot detect other than when they pass between "visible" objects, which are stars and us. the other type of black holes do spin and release huge amounts of radiation. When the black hole spins it develops into a toroid with a small radius of no matter inside of it. this is still within the event horizon, or the point that no object with mass can escape. very high energy things without mass traveling at the speed of light can. these are typicaly x rays and gamma rays. these make a symmetric plume to either side of the black hole which is detectable. This radiation.another thing about spinning black holes is that they aren't completely black. they radiate with what is known as "hawking radiation" named for stephen hawking a world renowned physicist. in high gravitational fields, such as near the event horizon for a black hole, as well as other high energy density situations pairs of particles, a particle and it's anti particle are created from free space. This is possible due to the law of charge conservation. the antiparticle has a the opposite charge of its counterpart. if the antiparticle is sucked in it obliterates something and the energy is released through hole in the middle. if the particle is sucked in it the free space that created the particle needs to get back to zero so energy is permitted to leave the black hole to fill the gap. this radiation as of yet isn't visible because it's temperature is less than the background microwave radiation of the universe.
