Modern physics began in the early 20th century with quantum theory and the theory of relativity. Each of these theories came about due to inaccuracies in classical mechanics in some cases. Classical mechanics predicted a varying speed of light, which could not be solved at the constant velocity predicted by Maxwell's electromagnetic equations; This discrepancy was corrected by Einstein's special theory of relativity, which replaced the classical mechanics of fast-moving objects and allowed for a constant velocity of light. Black-body radiation presented another problem for classical physics, which was corrected when Planck suggested that the excitation of material oscillators is only possible in discrete steps proportional to their frequency; This, combined with the photoelectric effect and a complete theory that predicts the discrete energy levels of electron orbits, led to a theory of quantum mechanics that took over from classical physics at very small scales. Quantum Mechanics will be led 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 a particle with properties compatible with the Higgs boson was discovered at CERN in 2012, all the basic particles predicted by the Standard Model, but not others, appear to be present. 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, such as the study of probabilities and groups.
In many ways, physics stems from ancient Greek philosophy. From Thales' first attempt to characterize matter, to Democritus, Ptolemaic astronomy of geocentrism, and Aristotle's Physics (an early book on physics, which attempted to analyze and define motion from a philosophical point of view), many Greek philosophers presented their own theories of nature. Physics was known as natural philosophy until the late eighteenth century.
While physics works to explain the laws of nature in general, each theory explains a restricted field. For example, we find that the laws of classical mechanics accurately describe systems whose size is greater than the atom and whose velocities are much less than the speed of light. As for outside those limits, we find that the viewing does not match the accounts.
Albert Einstein contributed to his special relativity formulation in 1905, which shows that there is no absolute place or time, and connected the two in what is called space-time for systems whose velocities are close to the speed of light. Subatomic particles and were able to give an accurate description of the nature of the atom and the nature of the elementary particles.
