  1. No, it's not. Teleportation requires a classical channel, i.e. limited by c. Fromn one of many articles on a recent experiment(emphasis mine): "The first step was to "entangle" two of the atoms. Their quantum properties were then precisely measured (doing so destroys the original quantum state) and those properties were then replicated by laser in the third atom, located eight microns (about a thousandth of an inch) away." This snippet makes the two points I've been hammering on for some time now: The measurement destroys the entanglement, and the information transfer is limited by c.
  2. I don't see how that follows.
  3. He balloon moves forward, CO2 balloon moves backward. From Newton's first law, the air in the van doesn't move forward with it until it builds up pressure to give it the required acceleration, so it builds up a little in the back. This exerts a pressure on the balloons and since the He is lighter, it is displaced forward relative to the van.
  4. Just last week it was announced that there were new findings in CP violations in B meson decay, with large asymmetries in the matter vs. antimatter decays - much larger than previously seen in Kaon decays.
  5. Or, you could do what is probably recommended in the instructions: let it sit for a minute or two before eating. This gives the food time to equilibrate - the hot spots cool, and the cold spots heat up, due to good ol' conduction.
  6. How did you do this test?
  7. let me add: We discussed microwave "dead zones" in the "ant in a microwave" thread. Add to that the feedback effect that frozen water is less likely to absorb the radiation than liquid water. So the area that defrosts first will then tend to be a more efficient absorber and heat up even faster. It's not so much the Hot Pockets engineers conspiring against you. It's Mother Nature herself.
  8. IOW, the second law of thermodynamics is a harsh mistress. Hardly a news flash. But snpssaini implied energy creation, and that it was a simple correction everybody else's wrong unbalanced wheel.
  9. You can state it a tad stronger than that. All conservation laws are equivalent to symmetries in the universe, by Noether's theorem (that's theorem, not theory; it's math without any conjecture) Conservation of energy is equivalent to time translation symmetry (this is not the same as time reversal, as in CPT). IOW, the laws of physics must change over time in order for energy not to be conserved.
  10. It's interesting to a point. But there's a point in all this where it crosses over from science to philosophy to mysticism, where I expect a link to Deepak Chopra and "Fine Structure Crystals for better quantum holistic living"
  11. YT didn't say you excite the photons, though. He was talking about photons interacting with the air.
  12. 81
  13. The spin value of a single particle is quantized - an electron can only be spin 1/2. This means it has 1/2 * h/2pi angular momentum (h/2pi = h-bar) If the spin changes, it can only do so in integral values of h-bar, so the electron can have +1/2 or -1/2 value of spin, depending on the direction of the angular momentum vector. Other particles are integral spin. When you start combining particles, you get into the problem of the various ways you can combine the angular momenta and what states are available.
  14. Well, women need to be aware that having Gerblimpenbooben leads to Gerblimpenboobendroopen later in life, for one.
  15. Are you asking if the electron "knows" its position and momentum better than the HUP?
  16. It's called the linear attenuation coefficient. (which is strange at first glance because it's a term in an exponential decay equation, as you note) The shielding depends on the number density and Z (atomic number). More atoms means more targets, as mentioned before, and higher Z also means more targets, because that's the number of electrons. A photon will interact via the photoelectric effect, Compton scattering, or pair production. The first two are interactions with the electrons, and the last takes place near a nucleus.
  17. They have to sum to the same value. Up = +1/2, Down = -1/2, total spin zero.
