Relating to Heraclitus, the ancient Greek philosopher known for teaching that everything is in constant flux and change.
From Heraclitus (540-480 BCE) + '-ean' (adjective suffix). Named after the philosopher who argued 'panta rhei' (everything flows), making this a philosophical/historical term.
Heraclitus said 'you can't step in the same river twice' because the water keeps changing—over 2,000 years later, quantum physics and ecology proved he was basically right about constant change being fundamental to reality.
