  1. It is not wearing anything that makes skydiving more interesting!
  2. Man, this sentence is ALL AROUND SFN!
  3. hmmmm... is it a good thing to lie?
  4. I bet it is! I got a friend who's Dan Brown addicted. It's sad to that man!
  5. Strangely, this reminds me something like:"What happens if you follow a photon at the speed of light?" "Well, the photons runs away at the speed of light!" It is indeed as you say Klay:D!
  6. That's very good moo! Good work with the chocolate... BTW, what kind of a chocolate was that?! And science does not have to be so extreme like the vid with duckies!
  7. Unfortunately! This is a thing that I think is non-sense about this forum! Why can't the name of the sender be displayed when you receive rep points? BTW, it sounds exotic Riogho>!
  8. OK, fair enough! I guess I was thinking V=cons!
  9. That's not what My intention was (which is clear enough) to show that anything with rest mass cannot reach c since infinite energy is needed, and this is shown good enough by the above equation I have pointed!
  10. Yeah yeah, but a membrane is vital. It's a fundamental necessity inside which everything (proteins and all) is located. Inside there! Don't push it any more or it will break!
  11. Indirectly! There was no referendum or such thing, only elections by which our institutions were chosen. Then it was those institutions, chosen by majority, that declared the independence which was the will of every albanian!
  12. Fair enough! And it tells the huge amount of energy stored in matter!
  13. Energy energy energy! You need infinite energy to send any kind of substance with rest mass at the speed of light! You easily work that out: As [math]m=\frac{m_0}{\sqrt{1-\beta^2}}[/math] then just replace m in [math]E=mc^2[/math] and you'll get: [math]E=\frac{m_0c^2}{\sqrt{1-\beta^2}}[/math] and taking v=300000km/s you will get zero under the fraction and anything divided by zero tends toward infinity, hence you need infinite energy!
  14. You don't really have to write [math]\frac{v^2}{c^2}[/math], you can simply write [math]\beta^2[/math] since [math]\beta=\frac{v^2}{c^2}[/math], it also refers to lightspeed!
  15. Yeah, a wavelength 'in there' is typically ~12.3cm. That's big enough!
  16. What you are saying is pure imagination! You cannot even imagine any kind of organism without a membrane. What about protection against harmful factors? Just leave the cellular material out there without any protection?!! No no, you REALLY need a membrane!
  17. Would you mind explaining more what you actually mean by your question. Because I find it hard to understand and to be honest I feel I've never heard of the subject before (although I have)!
  18. You can't bring a photon at rest! And yes you are correct. Photons have no rest mass, because sending an object with rest mass at the speed of light requires infinite energy (you can work that out very simply), and infinity is something beyond practice I believe!
  19. All the enormous variety of organisms today comes from a single cell, just one! Which at some point begun to 'live'! But what conditions must be filled in order to be alive? I still remember my first biology lesson in high school where we exactly talked about these conditions and we mentioned three: 1. A membrane 2. Energy Source 3. Reproductive Ability I. A membrane is highly necessary for a lot of reasons. The must 'primitive' reason is that a membrane holds the entire protoplasm together. Then the membrane also protects the protoplasm from harmful outside factors. Them is also serves as a port where all the substances that are needed in a cell go in, and the substances that no longer are useful go out. It is very important due to selective ability that membrane has (semi-permability). II. Energy is purely the fundamental condition needed to be filled so one cell (or organism) can keep living. Energy is needed to perform all the vital processes that happen in a cell and that make life possible. Of course energy is not needed in some physical processes (like diffusion or osmosis) which are passive, but energy indeed the key factor without which life just can't go on (at least no for long). After all, this is why we eat. Energy enters in different forms like carbohydrates, proteins, lipids etc. III. And reproductive ability is the third main condition that makes possible the continuity of life. Due to reproduction organisms proliferate, generation after generation and so life goes on continuously as an entirety although individual organisms die all the time. It is by reproduction that life counters death. Shade!
  20. Why time slows down? One day I was coming back from school with a friend of mine and we were discussing about effects of SR. Why does time has to slow? Why contraction? Why mass increase?, and the rest about SR. And talking, it came to his mind a very interesting picture of how time slows down! And it goes like this: Let's say that time come to us in frames (yeah just like frames in a movie, a PC game). And these frames come to us real fast and in everyday life we don't miss any of these frames, or even not a part of these frames and so we don't really 'lose' time. Or we do it in such a small value than cannot really be noticed. But when we travel fast enough (let's say 0.5C) then we begin to lose some of these frames. While the others at rest experience the whole frames coming to them, we lose some and so we experience less time. And we keep losing more and more frames as we move on faster and faster. And losing more and more frames means experiencing less and less time. I know it's not a serious thought, but it's an interesting picture of how time probably slows down. But why does it slow down? Well, I know of no explanation about this so far. Many think that this is not part of science, but I don't think that's right. It indeed is part of science but saying that it is not part of science is only due to little progress done on the filed!
  21. No it doesn't (AFAIK), neutron is simply neutral!
  22. [ce]Cl2[/ce] with [ce]H2O[/ce] will give you [ce]HCl + HOCl[/ce] and [ce]HOCl[/ce] will decompose into [ce]HCl[/ce] and atomic oxygen. They two ways I know of making [ce]HClO3[/ce] are: [ce]Cl2O5 + H2O -> 2HClO3[/ce] [ce]Ba(ClO3)2 + H2SO4 -> BaSO4 + 2HClO3[/ce]
  23. There is always a good explanation about almost everything at Wiki:
  24. That is what I meant to say:D
  25. Yup! More than 90% was pro-independence, and only serbians were against. And the number of countries that have recognized our independence and are in process of creating diplomatic relations is quite big.
