He was one of the earliest physicists to study radiation -- in his case the energy emitted by hot black bodies -- and in this domain he was to discover that the production and absorption of energy occurred in small finite amounts ("quanta") not in a infinitely changing gradation as required by classical (Newtonian) mechanics. It was Planck's calculation of the value of this quantum (1900-1901) that would lead Niels Bohr to realise that it related to regular and predictable changes of state at the sub-atomic level (such as the movement of an …
