Weyl's original 1918 theory posited spacetime-path-dependent scale changes, whereas quantum mechanical phase is a distinct mathematical structure with different physical interpretation.

No one has weighed in yet. Be the first to share reasons for or against this statement.

Physical interpretation(philosophy of science): An explanation of what abstract mathematical symbols or equations actually mean in the real, physical world.
Quantum mechanical phase(as a distinct alternative to Weyl's scale changes): A mathematical property in quantum mechanics (the physics of tiny particles) that describes the 'timing' or 'position' of a wave-like property of particles, similar to how sound waves can be in or out of sync.
Scale changes(as the physical phenomenon Weyl's theory describes): Changes in the size or magnitude of measurements; in this context, how the 'size' or 'scale' of physical quantities might shift as you move through space and time.
Spacetime(as one criterion for whether something is physically real): A physics concept combining space (location) and time into one continuous system—basically, every physical object exists somewhere at some moment in time.
