Now suppose that our Lagrangian has a timeindependent symmetry (we mean a symmetry as an invariance: something does not change under a set of transformations).
Special Post: Noether’s First Theorem – Emmy Noether for Ada Lovelace Day

The waveform with a given initial condition (its form at t = 0), remains a solution of the timeindependent SchrÃ¶dinger equation for all later times.

The Schrödinger Equation, cornerstone of quantum mechanics. (technically, this is a onedimensional, timeindependent, version of the equation).

And from that humble beginning — maybe ordinary quantum mechanics is right, and there exists a formulation of the theory of everything that takes the form of a timeindependent Hamiltonian acting on a timedependent quantum state defined in some Hilbert space — you can actually reach some sweeping conclusions.

Classically: dx/dt = p. If we choose to regard p as more fundamental than t then we “generate” time dt = dx/p. Or use a wavefunction ø: dø/dt = Hø (H a timeindependent Hamiltonian).

So in this sense, the ‘law’ being spiritual, is timeless and crosscultural and timeindependent.

Areas covered occasionally by sea ice are masked using a timeindependent mask.

Though some posts may be irrelevant to the present, this will give a new life to the posts which are timeindependent.

Insofar as this temporal factor of evaluations can be separated from timeindependent factors of evaluations, one speaks of pure time preferences.

Combined observational data from type Ia supernovas, galactic cluster abundances, gravitational lensing, and the apparent age of the universe favor a value of. that is more negative than about 0.8, tending to support Einstein's assumption of a constant timeindependent rL.
