A Brief History of the Generation of Physical Quantities from the Perspective of World Quantum Theory

In describing the world, humans have invented a series of physical quantities—velocity, mass, momentum, energy. They are not "discovered" objective existences, but tools constructed at specific historical stages to quantify phenomena. From the perspective of World Quantum Theory (WQT), this paper traces the generative process of these concepts from primitive perception to mathematization, pointing out that all physical quantities are essentially readings of the macro-rotation of the world quantum on different projection directions, and their "unification" comes from the same underlying structure—curvature GZ=1/λ2. Standard physics treats "readings" as "existence itself," which is the fundamental reason why it cannot unify quantum physics and classical physics.
