  1. I personally think only in mathematics.
  2. Yes, I think that is true (i.e. it doesn't matter). That is a long way past passing the Turing test though, which I am interpreting as an ability to fool a human over a short conversation.
  3. The difficulty here is going to be how does one assess conciousness or sentience. If you can't do that, then you will have difficulty deciding who or what these rights should be assigned to. I really don't think we are very far away from a digital personality passing the Turing test, but I don't think I would necessarily use that to distinguish sentience.
  4. I am going to try and answer these from a completely sceintific perspective, because I don't think they have been very well answered yet, no offence. 1. Science has conservation laws that prevent some things being created or destroyed. Mainly these are a consequency of symmetries in the laws of physics. For example, energy can't be created or destroyed, which is a consequnce of time translation symmetry of the laws of physics (the laws today are the same as yesterday). Particle number is not necessary conserved, though fermion number is. So electrons, for example can't be created unless a
  5. I have never had any issue combining my Christian faith with science.
  6. I don't think it has a wel defined limit. For large v, it will grow like v! (that is a factorial, not an exclamation). Edit: Ack! I take that back. I missed the s^(-v/2) at the front, which is exponential decay. The exponential trumps the factorial, so I think the limit is 0. Edit 2: Err... no, I think factorial trumps exponential, so now I am back to thinking it is infinite. Let's just check with mathematica..... and yes indeed it is infinite.
  7. If you could write the equation down where it appears, we might be able to tell you. Otherwise it is like asking on a web forum if anyone knows what my friends middle initial "Q" stands for.
  8. I hear that MIT is OK. Also Berkeley, Harvard, CalTech, Princeton, Cornell, Chicago, UC Santa Barbara in no particular order.
  9. No DM candidate that has been proposed has "no interaction" with matter. All of them do. But the neutrino itself is incredibly difficult to manipulate, so a very poor choice in using for DM discovery.
  10. Playing Beethoven is fair enough, but why the mockery of pretending that it is somehow spontaneous?
  11. Firstly, your maths is wrong. Secondly, the rest mass of the photon is zero, so [math]E=pc[/math]. Thirdly, "zero" does have meaning.
  12. Well, are you able to predict any of the meson masses then?
  13. That isn't a flash mob. It was clearly organised. Just because people don't all come at once doesn't make it a flash mob. Seems a bit pointless to me. Don't they have anything better to do?
  14. What makes you think the neutrino has anything to do with dark matter? It could be, since the sneutrino is a candidate, but it seems rather unlikely.
  15. newts: Can your theory predict the proton mass or the pion mass?
  16. I have to ask again: why? I can see no reason why both cannot be real, and you have presented no reason why both can't be real. In fact, the only thing that can be in conflict with current scientific findings is something that is measured under scientific conditions and is reproducable. Most religious traditions do not qualify, so can't be in contradiction with science.
  17. It is rather obvious that this result is not evidence of dark matter. But it is also not evidence that dark matter doesn't exist, even in particle form. There is still plenty of room in the parameter space.
  18. I disagree. The existence of scientific objects and God (in a general sense) are entirely consistent with each other.
  19. No - it is fundamental. You may as well claim that if we had the appropriate technology we could make [math]\pi[/math] smaller.
  20. I think it is pretty conclusive. Maybe not just this one instance, but there are plenty of other cases of gravitational lensing from unknown, non-radiating and thus "dark" objects in the universe.
  21. The uncertainty relation is purely a consequence of everything being composed out of waves (or more properly fields). A pure momentum state is like a sine wave, so infinitely spread out, while a purely localised wave is a superposition of an infinite number of plane waves of different wavelength (and thus momentum). The more localised in space the wave is, the more plane waves of different wavelength it needs, so the more uncertain the momentum.
  22. That is what I was (perhaps unsuccessfully) trying to get at when I said "The important thing is to channel conflict into productive avenues." I do still disagree though, since I still think "harmony" is the opposite of "conflict". Surely if you are in harmony, then you are doing something together, so can't be in conflict?
  23. There is tons of evidence for dark matter, from gravitational lensing, to WMAP, to galaxy rotation curves, to velocity dispersions, to supernova distances. I think the gravitational lensing and the relic density from WMAP would be enough evidence for me, never mind all the rest.
