Unification of theories about observable fundamental phenomena of nature is one of the primary goals of physics. [1] [2] [3] The two great unifications to date are Isaac Newton’s unification of gravity and astronomy, and James Clerk Maxwell’s unification of electromagnetism; the latter has been further unified with the concept of electroweak interaction.
Sir Isaac Newton (/ ˈ nj uː t ən /; 25 December 1642 – 20 March 1726/27) [a] was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author. [5] Newton was a key figure in the Scientific Revolution and the Enlightenment that followed. [6]
1672: Sir Isaac Newton: discovers that white light is a mixture of distinct coloured rays (the spectrum). 1673: Christiaan Huygens: first study of oscillating system and design of pendulum clocks; 1675: Leibniz, Newton: infinitesimal calculus. 1675: Anton van Leeuwenhoek: observes microorganisms using a refined simple microscope.
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.
1705 – Edmond Halley predicts the return of Halley's comet in 1758, [11] the first use of Newton's laws by someone other than Newton himself. [12] 1728 – Isaac Newton posthumously publishes his cannonball thought experiment. [13] [14] 1742 – Colin Maclaurin studies a self-gravitating uniform liquid drop at equilibrium, the Maclaurin ...
1671: Newton–Raphson method – Joseph Raphson (1690), Isaac Newton (Newton's work was written in 1671, but not published until 1736). 1696: Brachistochrone problem solved by Johann Bernoulli, Jakob Bernoulli, Isaac Newton, Gottfried Wilhelm Leibniz, Guillaume de l'Hôpital, and Ehrenfried Walther von Tschirnhaus. The problem was posed in ...
Brahe and Kepler, along with Sir Isaac Newton and Galileo Galilei, were giants who replaced the medieval view of the world with a modern one, said Kaare Lund Rasmussen, lead author of the Brahe ...
In the 19th century, the basic laws of electromagnetism and statistical mechanics were discovered. 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.
