Newtonian
UK: njuːˈtəʊniən | US: nuːˈtoʊniən
adj. relating to or based on the work of Sir Isaac Newton
adj. following the principles of classical physics, especially Newton's laws of motion
n. a person who adheres to Newtonian physics
The term "Newtonian" derives from the name of Sir Isaac Newton (1643–1727), the foundational figure in classical mechanics. The suffix "-ian" (from Latin "-ianus") denotes relation or belonging, forming adjectives meaning "pertaining to" or "following the principles of." Thus, "Newtonian" originally described concepts or individuals aligned with Newton's theories, particularly his laws of motion and universal gravitation. Over time, it became a standard term in physics to distinguish classical mechanics from later frameworks (e.g., Einsteinian relativity).
Newtonian physics explains planetary motion with remarkable accuracy.
The professor specializes in Newtonian dynamics.
Early engineers relied heavily on Newtonian principles.
Quantum mechanics challenged many Newtonian assumptions.
A strict Newtonian would reject the idea of action at a distance.
