Quantum Trickery - Einstein's Strangest Theory

breckinshire writes "The New York Times is running an interesting story on Einstein's strangest theory. The theory was brought to light this past fall when 'scientists announced that they had put a half dozen beryllium atoms into a "cat state." [...] These atoms were each spinning clockwise and counterclockwise at the same time.' It is an interesting writeup for even the uninitiated and also concentrates on Einsteins role as a 'founder and critic of quantum theory.'"

      Planck, Heisenberg, Pauli, Dirac, Schrodinger and Einstein are each the single founder of quantum mechanics in different superimposed universes. It is impossible for us to find out in which of these universes we live without killing all the cats,

      Einstein was a founder of quantum theory, along with Planck, Heisenberg, Pauli, Dirac, Schrodinger and many many more. There was no single founder.

      Of course there was a single founder, but his identity is uncertain. Whenever you ask a scientist, you can't be certain beforehand who he'll name; you can only say that the founder will be named as a certain person with certain propability.

    "To a physicist, a "cat state" is the condition of being two diametrically opposed conditions at once, like black and white, up and down, or dead and alive."

    Actually, this term was coined by Nikola Tesla and refered to his observations of the violent sub-molecular reaction created when a cat with a cheese pizza tied to its back is dropped onto expensive carpeting. What, you didn't think that his silly "death ray" is what caused the Tunguska event, did you?

      I thought it was supposed to be a slice of buttered toast strapped butter-side up to the cat's back; the feline-toast turbine, which operates on the principals of:

      1 - A cat always lands on its feet.
      2 - A slice of buttered toast, when dropped on an expensive carpet, will always land butter-side down.

    Read this article and then go play sudoku in your paper (don't know what it is? do a search, and you will learn). I think my head my just explode in a moment. I keep seeing entanglements and cat states. this box is both a "9" and "8" until i pick one. But the box all the way over there that's an "8" means that this can't be, but that it might be a "6" instead. So if this is "6" than i know that is "8" and therefore that one is "9". Dang Einstein ruining a good game even after he's dead.

  18. This is a bug in physics by FryingLizard · · Score: 2, Funny
    You know what it is, this Quantum stuff; scientists have finally discovered a pointer error in physics.

    From the article:
    These atoms were each spinning clockwise and counterclockwise at the same time. Moreover, like miniature Rockettes they were all doing whatever it was they were doing together, in perfect synchrony. Should one of them realize, like the cartoon character who runs off a cliff and doesn't fall until he looks down, that it is in a metaphysically untenable situation and decide to spin only one way, the rest would instantly fall in line, whether they were across a test tube or across the galaxy.

    Any halfway competent C programmer can easily see this is simple pointer aliasing. Physics was clearly written in C++ - albeit with a very high precision floating point library. What is happening is that, to save memory on the galaxy, most of the different atoms we perceive are actually just the same one, aliased using pointers. There is some neat code in Physics.cpp which detects when an atom is modified and makes a mutable copy as required. Clearly in this case (with the atom, cat, whatever) something is fux0red in the code and it's not making a copy; hence modifying one atom modifies the perceived value of several. Fortunately as soon as a human observes it, atom->View() is called, and a stable copy of the atom is created and from then on the bug kinda disappears (all the atoms go about their business as normal).

    As a bug, it probably got noticed in beta, but was considered low priorty, however now there's such a fuss about it, I'd expect an online patch to stop the scientist hax0rs exploiting "the Quantum effect" any millenium now, so don't go writing it into your world view.

    (Incidentally, this is why people die, it's to avoid problems with them knowing too much and causing stack overflows, but that's another story)
