Just in case you’ve all forgotten what the LHCb detector looks like, I’ve included a schematic below. The muon subsystem is the rightmost one, with alternating layers of light [...]

    Supersymmetry is not confirmed by any experiment, not even by the LHC. What does a theoretician say? Urs Schreiber answers: The 1922 Stern-Gerlach experiment, which established spin 1/2, is a proof that world-line supersymmetry exists.The reasoning is so blatantly false that I must ask: how can a smart man like Urs Schreiber write something so false? We all wish you that you recover soon. Find a caring person that helps you!

    Updated: 2011-07-26 17:50:02
    (PhysOrg.com) -- When it comes to the rules of the quantum world, it seems that almost everything goes against intuition. In the case of the way ignorance of the whole implies ignorance of at least one of its parts, the situation seems to be counterintuitive. "When viewed in a classical sense, you would be inclined to think that a strong ignorance of the whole has to be accompanied by significant ignorance of at least one of its parts," Stephanie Wehner tells PhysOrg.com. "However, this conjecture turns out to be false in quantum theory."
