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.
4th century BC: The first true formal system is constructed by Pāṇini in his Sanskrit grammar. [34] [35] 4th century BC: Eudoxus of Cnidus states the Archimedean property. [36] 4th century BC: Thaetetus shows that square roots are either integer or irrational. 4th century BC: Thaetetus enumerates the Platonic solids, an early work in graph ...
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 ...
He wrote the first work which refers to that line of study as "Physics" – in the 4th century BCE, Aristotle founded the system known as Aristotelian physics. He attempted to explain ideas such as motion (and gravity) with the theory of four elements. Aristotle believed that all matter was made up of aether, or some combination of four ...
424 BC Aristophanes' "lens" is a glass globe filled with water.(Seneca says that it can be used to read letters no matter how small or dim) [4] 4th century BC Mo Di first mentions the camera obscura, a pin-hole camera. 3rd century BC Euclid is the first to write about reflection and refraction and notes that light travels in straight lines [4]
4th century BC - Aristotle invents the system of Aristotelian physics, which is later largely disproved; 4th century BC - Babylonian astronomers calculate Jupiter's position using the Trapezoidal rule [1] 260 BC - Archimedes works out the principle of the lever and connects buoyancy to weight
2000 scientists at Fermilab announce the first direct evidence for the tau neutrino, the third kind of neutrino in particle physics. [30] 2000 CERN announced quark-gluon plasma, a new phase of matter. [34] 2001 the Sudbury Neutrino Observatory (Canada) confirm the existence of neutrino oscillations.
The 1st century was the century spanning AD 1 (represented by the Roman numeral I) through AD 100 (C) according to the Julian calendar. It is often written as the 1st century AD or 1st century CE to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical ...
