Black-body radiation and the forgotten heritage of Max Planck

Besides the discovery of the fourth fundamental physical constant h, Max Planck (1858-1947) has solved various important problems in physics. Beyond their mere historical interest, Planck’s several forgotten results still may have relevance even in the everyday practice of modern physics, including for instance laser noise or entanglement. On the occasion of his 160th birthday, we retrace Planck’s lesser known original thoughts concerning the black-body radiation problem, and also deal with his second theory, which already contained the concept of induced emission and zero-point energy. Finally we show Planck’s original derivation of the natural system of units (Planck length, mass, time and temperature), which plays a distinguished role in cosmological physics.
