Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...
