This, together with the photoelectric effect and a whole theory that predicts discrete energy levels for electronic orbitals, led to a theory of quantum mechanics that took over from classical physics on very small scales. Quantum mechanics will be played by Werner Heisenberg, Erwin Schrödinger and Paul Dirac. From this early work, and work in related fields, the Standard Model of particle physics was derived. After the discovery of a particle with properties consistent with the Higgs boson at CERN in 2012, it appears that all the fundamental particles predicted by the Standard Model, and not much else, exist; However, physics outside the Standard Model, with theories such as supersymmetry, is an active area of research. Areas of mathematics in general are important in this field, as is the study of probabilities and groups.

Solvay Conference of 1927, with prominent physicists such as Albert Einstein, Werner Heisenberg, Max Planck, Hendrik Lorentz, Niels Bohr, Marie Curie, Erwin Schrödinger and Paul Dirac.
Main article: Philosophy of physics
In many ways, physics stems from ancient Greek philosophy. From Thales' first attempt to characterize matter, to Democritus, Ptolemaic geocentric astronomy, and Aristotle's Physics (an early book on physics that attempted to analyze and define motion from a philosophical point of view), many Greek philosophers offered their own theories of nature. Physics was known as natural philosophy until the late eighteenth century.
