The discovery of the Planck constant enabled him to define a new universal set of physical units (such as the Planck length and the Planck mass), all based on fundamental physical …

Nov 18, 2025 · Max Planck, German theoretical physicist who originated quantum theory, one of the fundamental theories of modern physics, for which he won the 1918 Nobel Prize for Physics.

This was not only Planck’s most important work but also marked a turning point in the history of physics. The importance of the discovery, with its far-reaching effect on classical physics, was …

Max Planck changed physics and our understanding of the world forever when he discovered that hot objects do not radiate a smooth, continuous range of energies as had been assumed in …

Planck himself said that, despite having invented quantum theory, he did not understand it himself at first. Nevertheless, he received the Nobel Prize for Physics in 1918 for his achievement.

Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory. In addition to being a physicist, …

Planck received the Nobel Prize in physics in 1918 for his quantum theory after it had been successfully applied to the photoelectric effect by Einstein and the atom by Niels Bohr.

2 days ago · Planck’s theory held that radiant energy is made up of particle-like components, known as “quanta.” The theory helped to resolve previously unexplained natural phenomena …

The German physicist Max Planck was the discoverer of the quantum of action, also called Planck's constant. Born in Kiel, he studied physics and mathematics at the University of …

By interpolating between the laws of Wien and Rayleigh-Jeans, Planck formulated the now-famous Planck's law of black-body radiation, which described the experimentally observed …
