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.
A golden age of physics began with the simultaneous discovery of the principle of the conservation of energy in the mid-19th century. [7] [8] A golden age of physics was the years 1925 to 1927. [9] The golden age of nonlinear physics was the period from 1950 to 1970, encompassing the Fermi–Pasta–Ulam–Tsingou problem and others. [10]
The timeline begins at the Bronze Age, as it is difficult to give even estimates for the timing of events prior to this, such as of the discovery of counting, natural numbers and arithmetic. To avoid overlap with timeline of historic inventions , the timeline does not list examples of documentation for manufactured substances and devices unless ...
Even if material properties were modeled before 1900, condensed matter topics were considered as part of physics since the development of quantum mechanics and microscopic theories of matter. According to Philip W. Anderson , the term "condensed matter" appeared about 1965.
Physics was transformed by the discoveries of quantum mechanics, relativity, and atomic theory at the beginning of the 20th century. Physics today may be divided loosely into classical physics and modern physics. Detailed articles on specific topics are available through the Outline of the history of physics.
For a more detailed timeline of aether theories – e.g. their emergence with the wave theory of light – see a separate article. Also, not all experiments are listed here – repetitions, even with much higher precision than the original, are mentioned only if they influence or challenge the opinions at their time. It was the case with:
Today, Musk ranks as the richest person in the world, according to Bloomberg, largely thanks to his roughly 13 percent stake in Tesla, which was worth about $103 billion as of October 2024.
1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
