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 discovery finally convinces the physics community of the quark model's validity. 1974 Robert J. Buenker and Sigrid D. Peyerimhoff introduce the multireference configuration interaction method. 1975 Martin Perl discovers the tau lepton; 1977 Leon Lederman observes the bottom quark with his team at Fermilab. [30]
1853 – Discovery of Wiedemann–Franz law relating thermal and electrical conductivities, by Gustav Wiedemann and Rudolph Franz. [34] 1854 – Lord Kelvin discovers the thermoelectric Thomson effect. [35] 1859 – Gustav Kirchhoff introduces the concept of a blackbody and proves that its emission spectrum depends only on its temperature. [36]
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.
1676 – Ole Rømer gives the first piece of evidence that the speed of light is finite, through his observation of the moons of Jupiter; [2] the discovery divides scientists of his time. [3] 1690 – Christiaan Huygens gives the first estimate of the speed of light in air or vacuum, based on Rømer’s work.
2013 – NuSTAR and XMM-Newton measure the spin of the supermassive black hole at the center of the galaxy NGC 1365. [242] 2015 – Advanced LIGO reports the first direct detections of gravitational waves, GW150914 [243] and GW151226, [244] mergers of stellar-mass black holes. Gravitational-wave astronomy is born. [245]
This discovery of the wave–particle duality of matter and energy is fundamental to the later development of quantum field theory. 1909 and 1916 – Einstein shows that, if Planck's law of black-body radiation is accepted, the energy quanta must also carry momentum p = h / λ , making them full-fledged particles .
