Physics is the human-made discipline of systematic study of natural phenomena — matter, energy, space, time, and their interactions. It operates through a cycle of observation, mathematical modeling, experimental testing, and theoretical refinement. Its persistence mechanism is institutional: university departments, peer-reviewed journals, research funding bodies, and educational curricula that reproduce the practice across generations. Physics produces a body of theories (classical mechanics, electromagnetism, quantum mechanics, relativity) that make quantitative predictions about observable phenomena, with each theory defining a domain of validity rather than an absolute truth.

Definition
Why it is in scope
The human-made discipline of systematic study of natural phenomena — matter, energy, and their interactions. Built as a formal framework of models, experiments, and mathematical description that persists through institutions, publications, and teaching.

Physics uses mathematical formalism as its operating language. Remove mathematics and physics stops working as an explanatory and predictive framework — it becomes mere observation without the structure to model relationships, derive predictions, or quantify causation. The removal test passes: physics requires math to OPERATE, not just to be described.

Optics as a scientific discipline was derived from physics. Physics existed first (as the broader study of matter and energy) and fed into optics, which specialized into the study of light. Which-came-first test: physics is older and more general, optics branched from it.
