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.
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 ...
The timeline of historic inventions is a chronological list of particularly significant technological inventions and their inventors, where known. [ a ] The dates in this article make frequent use of the units mya and kya , which refer to millions and thousands of years ago, respectively.
The conceptual differences between physics theories discussed in the 19th century and those that were most historically prominent in the first decades of the 20th century lead to a characterization of the earlier sciences as "classical physics" while the work based on quantum and relativity theories became known as "modern physics".
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 ...

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.
This is a timeline of subatomic particle discoveries, including all particles thus far discovered which appear to be elementary (that is, indivisible) given the best available evidence. It also includes the discovery of composite particles and antiparticles that were of particular historical importance.
