That is out of consideration! Quarks have rest mass. Photons don't! It is a very rough attempt to clarify! What wasn't clear for me is that I thought annihilation process took place only by opposite charge!

Cmac, universe has no center, and the strange stuff is that you can put anything or anyone you want in the center! Look at this! it is useful and easy to find out why!

When we dealt with this at school we did it this way. The work of electricity is: [math]A=IUt[/math] the unit turn out fine too because Ampere*Volt*sec gives joule! And as we all know the formula for power is: [math]P=\frac{A}{t}={IUt}{t}[/math] we cancel t and get: [math]P=UI[/math] so in this case it is the product of tension and intensity! And you very easily proof the unit. [math]P(=)IU=A\times V[/math] as [math]1A=\frac{1C}{1s}[/math] and [math]1V=\frac{1J}{C}[/math] so you'd get: [math]P(=)\frac{C}{s}\frac{J}{C}[/math] cancel Cs and finally [math]P(=)\frac{J}{s}=W[/math] Cheers, Shade

Every droplet of water serves like a prism and here we get the light spectrum. The white light is decomposed and gives the beautiful colors you see in the rainbow! Cool pic iNow. Rainbow Six!

Reward? It's my first time that I hear of this!... Is there any option that allows you to do that?

it's very hard to follow Alex. Could you please LaTeXise it? If you don't know, browse the forum for a LaTeX tutorial. It's easy to use it and will make things much clearer! I hope you understand! Cheers

I don't know in which part of California is it, but I've followed some online lectures of University of California - Berkley , and I found them quite good quality! They were not actually PhD programs, but I'm sure you'll find something worth it! Cheers, Shade

Is that an annihilation process? Because neutrons have no charge, so you can't really cancel charges when you have no charge at all, and I find that a bit strange. Or is it just a fancy way of doubting a post?

Yup, it is one of the strongest bases. One of its features is also that it is hygroscopic, which means that it has the ability of absorbing water from air. If left in air NaOH acts with CO2 as in the following equation: [ce]2NaOH + CO2 -> Na2CO3 + H2O[/ce]

One thing I learned at school is to cut details when possible, and I think that applies here too! What you have said is a brilliant interpretations but I think it should be less complicated than that. I was thinking like, antimatter is the same as ordinary matter but only with opposite charge. Electron vs. positron & proton vs antiproton both result in annihilation and complete release of energy. And a photon does not have charge, hence it cannot have antimatter! The oposite of zero is still zero!

There also is: frequency=[math]\frac{v}{\lambda}[/math] (I don't know the LaTeX for frequency)

I've heard that hydrogen bombs need more than 100 million C, since the explosion is supposed to take place in a millionth of a second. Is that true?

Universe is infinite (at least we all seem to think that way)! And because it is infinite, it can stand infinite expansions, and thus in can stand infinity. Infinite matter fits in infinity too! Simply because it is located in something that is infinite! There is a lot of room in infinity you know!

What would happen in the poles?

To happen fusion a very very good deal of energy is needed. In CRTs temperatures have peaked 100 million C, and I don't know it that's enough hot for fusion. Sometimes even the nucleus of sun isn't hot enough to fuse, simply because the needed temperature is extremly hot!

Yeah fasttoyotapu , that is the reaction! [ce]2Na + 2H2O -> 2NaOH + H2[/ce] All the elements of I and II group (with few exceptions) when reacting with water give the the base (in this case NaOH) and hydrogen is released. In the reaction above, there also is released a good deal of energy (so the reaction is exothermic), but unless localized that energy isn't enough to set hydrogen on fire. Cheers, Shade

With the increase of wavelength, the frequency decreases, since frequency it is indirectly depended from wavelength. That's explained better in Doppler effect!

Intelligence vs happiness??? I'm of average intelligence, sometimes happy, but most of the time fully depressed! Am I an aloner?

But that doesn't mean that is the animal's main way of breathing! Take frogs for example! They breathe in two ways, by lungs (using nostrils) and by skin. But if we seal the pores on a frog's skin, the frog will soon die. That shows that it breathes more with skin than lungs, although when frogs appeared there was enough oxygen! You just mentioned one of the advantages, the keep of constant temperature. Changes in temperature have quite a lot effects in any organism. All organisms are sensitive to changes in temperature, so they have developed special methods of keeping the temperature constant and so they suffer not big changes, and one of them is transpiration! We too have a sort of transpiration, sweat! And as far as I know, there is nothing bad with sweating (except the smell), because by sweat we keep the temperature constant in our organism!

I got started with Python (like may here proposed me) and I found it quiet good for a beginner, then moved on to Basic and now I'm working on C++, but it's hell of complicated language!

Thanks Klaynos, I'll just run to amazon to buy it! Cheers!

Hey Klaynos, could you recommend a web site, pfd download or a good book where I could get a real detailed sense of QM? I'm thinking of something, and just want to find out! That'd be really appreciated! Thnx

Yeah! [math]\epsilon=\frac{\epsilon_r}{\epsilon_0}[/math]

I know Atheist, and there is just one mistake on the whole equation (it's that damn +1 at the end that should have been -1), and screws up my calculation and makes me sad:doh:!

Norman, could you say what you just said, but in a more normal and "easy to understand" way?
