The classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all...

Classical physics refers to physics theories that are non-quantum or both non-quantum and non-relativistic, depending on the context. In historical discussions...

Classical Greece was a period of around 200 years (the 5th and 4th centuries BC) in ancient Greece, marked by much of the eastern Aegean and northern...
