Instantly acquire all the knowledge you need to pass as an expert in the world of quantum physics from Bluffer's Guide to the Quantum Universe. Never again confuse a boson with a hadron, a fermion with a meson, or a photon with a lepton or an electron. If in doubt, always fall back on a bluffon.Bask in the admiration of your fellow physicists as you pronounce confidently on the theories of superstrings and entanglement, and hold your own in any discussion about Schrödinger's Cat. And in moments of uncertainty always resort to the tried and tested rejoinder: 'They're addressing that at CERN.'
