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.
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.
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 ...
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.
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]
If you were bummed that this fall's Creators Update for Windows 10 didn't include Microsoft's version of Handoff, we feel you. But if you're a Windows Insider Program member, there's good news ...

2021 – Jun Ye and his team measure gravitational redshift with an accuracy of 7.6 × 10 −21 using an ultracold cloud of 100,000 strontium atoms in an optical lattice. [ 296 ] [ 297 ] 2021 – EHT measures the polarization of the ring of M87*, [ 298 ] and other properties of the magnetic field in its vicinity.
