Физика

Фи́зика (от др.-греч. φύσις — природа) — область естествознаниянаука о простейших и, вместе с тем, наиболее общих законах природы, о материи, её структуре и движении. Законы физики лежат в основе всего естествознания.

Термин «физика» впервые фигурирует в сочинениях одного из величайших мыслителей древности — Аристотеля (IV век до нашей эры). Первоначально термины «физика» и «философия» были синонимами, так как в основе обеих дисциплин лежало стремление объяснить законы функционирования Вселенной. Однако в результате научной революции XVI века физика развилась в самостоятельную научную отрасль.

В современном мире значение физики чрезвычайно велико. Всё то, чем отличается современное общество от общества прошлых веков, появилось в результате применения на практике физических открытий. Так, исследования в области электромагнетизма привели к появлению телефонов и позже мобильных телефонов, открытия в термодинамике позволили создать автомобиль, развитие электроникипривело к появлению компьютеров. Развитие фотоники способно дать возможность создать принципиально новые — фотонные — компьютеры и другую фотонную технику, которые сменят существующую электронную технику. Развитие газодинамики привело к появлению самолётов и вертолётов.

Знания физики процессов, происходящих в природе, постоянно расширяются и углубляются. Большинство новых открытий вскоре получают техникоэкономическое применение (в частности в промышленности). Однако перед исследователями постоянно встают новые загадки, — обнаруживаются явления, для объяснения и понимания которых требуются новые физические теории. Несмотря на огромный объём накопленных знаний, современная физика ещё очень далека от того, чтобы объяснить все явления природы.

Общенаучные основы физических методов разрабатываются в теории познания и методологии науки.

В русский язык слово «физика» было введено М. В. Ломоносовым, издавшим первый в России учебник физики — свой перевод с немецкого языка учебника «Вольфианская экспериментальная физика»Х. Вольфа (1746)[3]. Первым оригинальным учебником физики на русском языке стал курс «Краткое начертание физики» (1810), написанный П. И. Страховым.
