A man sits down before a gun , which is pointed at his head. This is no ordinary gun; it's rigged to a machine that measures the spin of a quantum particle .
Classical physics could not explain the spectra of black bodies. It predicted that the intensity (power emitted at a given wavelength) of emitted light should increase rapidly with decreasing wavelength without limit (the "ultraviolet catastrophe"). In the figure below, the curve labeled "Rayleigh-Jeans law" shows the classically expected behavior.
