Main article: Photoelectric effect In another paper published in that same year, Albert Einstein undermined the very foundations of classical electromagnetism. His theory of the photoelectric effect (for which he won the Nobel prize for physics) posited that light could exist in discrete particle-like quantities,...

Classical electrodynamics
Main article: Classical electrodynamics The scientist William Gilbert proposed, in his De Magnete (1600), that electricity and magnetism, while both capable of causing attraction and repulsion of objects, were distinct effects. Mariners had noticed that lightning strikes had the ability to disturb a compass needle,...
Overview
The electromagnetic force is amongst the four known fundamental forces. The other fundamental forces are: the strong nuclear force, which binds quarks to make nucleons, and binds nucleons to nuclei, the weak nuclear force, which in turn causes certain forms of decay, and the gravitation....
History of the theory
See also: History of electromagnetic theory Originally electricity and magnetism were considered two separate forces. This view changed, however, with the publication of James Clerk Maxwell’s 1873 Treatise on Electricity and Magnetism the location where the interactions of bad and the good charges were been...
Electromagnetism
Electromagnetism is the branch of science related to the forces that occur between electrically charged particles. In electromagnetic theory these forces are explained using electromagnetic fields. Electromagnetic force is one of the four fundamental interactions in the wild, the opposite three being the strong interaction,...
Klimato
Ĝenerale hegemonias vintroj kaj someroj longaj kaj rigoraj, propraj de la kontinentaj klimatoj; kaj en la montaraj zonoj de nordo kaj sudo, la temperaturoj propraj de altaĵoj kaj laŭ la orientiĝo de ties montoj. Tiu ĉi provinco karakteriĝas pro sia sekeco dum du trionoj de...
