Modern physics is a branch of physics that developed in the early 20th century and onward or branches greatly influenced by early 20th century physics. Notable branches of modern physics include quantum mechanics , special relativity , and general relativity .
Kenneth Krane's Modern physics begins a text on quantum and relativity theories with a few pages on the deficiencies of classical physics. [84]: 3 E.T. Whittaker's two volume A History of the Theories of Aether and Electricity subtitles volume one to The Classical Theories and volume two The Modern Theories (1900–1926). [85]
The theory of the strong interaction (i.e. quantum chromodynamics, QCD), to which many contributed, acquired its modern form in 1973–74 when asymptotic freedom was proposed [23] [24] (a development that made QCD the main focus of theoretical research) [25] and experiments confirmed that the hadrons were composed of fractionally charged quarks.

Modern quantum mechanics implies that uncertainty is inescapable, and thus that Laplace's vision has to be amended: a theory of everything must include gravitation and quantum mechanics. Even ignoring quantum mechanics, chaos theory is sufficient to guarantee that the future of any sufficiently complex mechanical or astronomical system is ...

Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
The International Journal of Modern Physics C was established in 1990. It covers specifically computational physics , physical computation and related subjects, with topics such as astrophysics , computational biophysics, materials science , and statistical physics.
