Classical physics is the physics you can actually watch working around you. This page collects Astrinova's reporting on motion and forces, energy and momentum, gravity and orbits, waves and sound and optics, heat and thermodynamics, fluids and pressure, and electricity and magnetism, the framework that explained falling apples, swinging pendulums, steam engines, and electric currents long before quantum mechanics and relativity took over the frontier. None of it stopped being true when physics moved on. It is still the physics running your car engine, your kitchen stove, and the bridge you drive over every day. This page tracks how those old, tested laws still explain the ordinary world, and where their limits eventually show up.
