Picture an atom, and you may imagine spherical electrons orbiting a nucleus packed with particles like neutrons. Only certain orbits - quantum levels - are possible. It's a simplistic model, yet ...

Physicists from the Canadian Institute for Measurement Standards are the first to measure a quantum mechanical wave function. And it only took 88 years from the formulation of Schroedinger’s equation!
