Page "Quantum mechanics" Paragraph 9

The foundations of quantum mechanics were established during the first half of the 20th century by Max Planck, Niels Bohr, Werner Heisenberg, Louis de Broglie, Arthur Compton, Albert Einstein, Erwin Schrödinger, Max Born, John von Neumann, Paul Dirac, Enrico Fermi, Wolfgang Pauli, David Hilbert, Wilhelm Wien, Satyendra Nath Bose, Arnold Sommerfeld and others.

In the mid-1920s, developments in quantum mechanics led to its becoming the standard formulation for atomic physics.

In the summer of 1925, Bohr and Heisenberg published results that closed the " Old Quantum Theory ".

Out of deference to their particle-like behavior in certain processes and measurements, light quanta came to be called photons ( 1926 ).

From Einstein's simple postulation was born a flurry of debating, theorizing, and testing.

Thus the entire field of quantum physics emerged, leading to its wider acceptance at the Fifth Solvay Conference in 1927.
