Image captures light as both wave and particle for very first time

In 1905, Albert Einstein provided an explanation of the photoelectric effect - that various metals emit electrons when light is shined on them - by suggesting that a beam of light is not simply a wave of electromagnetic radiation, but is also made up of discrete packets of energy called photons. Though a long accepted tenet in physics, no experiment has ever directly observed this wave/particle duality. Now, however, researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switze...
