In Concepts of Modern Physics Arthur Beiser starts with a definition of modern physics: [83] Modern physics began in 1900 with Max Planck’s discovery of the role of energy quantization in blackbody radiation, a revolutionary idea soon followed by Albert Einstein’s equally revolutionary theory of relativity and quantum theory of light.
The history of quantum mechanics is a fundamental part of the history of modern physics. The major chapters of this history begin with the emergence of quantum ideas to explain individual phenomena—blackbody radiation, the photoelectric effect, solar emission spectra—an era called the Old or Older quantum theories.

The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
The beginning of the 20th century brought the start of a revolution in physics. The long-held theories of Newton were shown not to be correct in all circumstances. Beginning in 1900, Max Planck, Albert Einstein, Niels Bohr and others developed quantum theories to explain various anomalous experimental results, by introducing discrete energy levels.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
Einstein, in 1905, when he wrote the Annus Mirabilis papers. 1900 – To explain black-body radiation (1862), Max Planck suggests that electromagnetic energy could only be emitted in quantized form, i.e. the energy could only be a multiple of an elementary unit E = hν, where h is the Planck constant and ν is the frequency of the radiation.
Thomas Young - the first to use the term "energy" to refer to kinetic energy in its modern sense, in 1802.. In the history of physics, the history of energy examines the gradual development of energy as a central scientific concept.
Physics is the scientific study of matter, ... but did not rely on experimental verification of deduced statements. ... Modern physics began in the early 20th century ...
