Drama in Quantum Physics Teaching—Following Uncle Albert and Alice into Quantumland

Quantum mechanics has been enormously successful. The equations and rules enable accurate calculations and predictions of energies and other properties of atoms, molecules, and materials. Quantum-physics-based technology is an integrated part of our daily lives. Still, the understanding and interpretation of quantum physics offer many challenges, with the counterintuitive consequences of the rules, from the mythical “Schrödinger’s cat,” over single-photon double-slit experiments, to the Einstein–Podolsky–Rosen (EPR) paradox, formulated in 1935.
