Klassikal fysiks

Di foh major domains of modern fysiks

Klassikal fysiksbi a grup offysikstheoris wey predayt modern, moh komplit, or moh waidly applikabul theoris. If a korrently asepted theori dé konsidad to bi modern, and e introdukshion reprisent a majorparadaim shift,then di previous theoris, or niu theoris bayzd on di olda paradaim, ga often dé referd to as belongin to di area of "klassikal fysiks".

As such, di definishion of a klassikal theori depends on kontex. Klassikal fysikal konsepts often dé yuzd wen modern theoris unnecessarily de komplex for a partikula situashion. Most often,klassikal fysiksrefers to pre-1900 fysiks, whilemodern fysiksrefers to post-1900 fysiks, which inkorporayts elements ofquantum mekaniksandrelativity.
