Elementary Particle holding electromagnetic radiation. Both a particle and a wave. It is the necessary consequence of physical laws having a certain symmetry at every point in spacetime. The photon has led to momentous advances such as lasers, Bose–Einstein condensation, quantum field theory, the probabilistic interpretation of quantum mechanics, measurements of molecular distances and quantum cryptography. But the most important thing it does, is let me see your face when your more than a marathon away.
