  2. Relative dating - Wikipedia

    en.wikipedia.org/wiki/Relative_dating

    The law of included fragments is a method of relative dating in geology. Essentially, this law states that clasts in a rock are older than the rock itself. [ 6 ] One example of this is a xenolith , which is a fragment of country rock that fell into passing magma as a result of stoping .

  3. Williams–Landel–Ferry equation - Wikipedia

    en.wikipedia.org/wiki/Williams–Landel–Ferry...

    The WLF equation is a consequence of time–temperature superposition (TTSP), which mathematically is an application of Boltzmann's superposition principle. It is TTSP, not WLF, that allows the assembly of a compliance master curve that spans more time, or frequency, than afforded by the time available for experimentation or the frequency range ...

  4. Superposition principle - Wikipedia

    en.wikipedia.org/wiki/Superposition_principle

    The superposition principle, [1] also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

  5. Quantum superposition - Wikipedia

    en.wikipedia.org/wiki/Quantum_superposition

    Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation. This follows from the fact that the Schrödinger equation is a linear differential equation in time and position.

  6. Law of superposition - Wikipedia

    en.wikipedia.org/wiki/Law_of_superposition

    The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields pertaining to geological stratigraphy.In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will lie at the bottom of the sequence, while newer material stacks upon the surface to form new deposits over time.

  7. Time–temperature superposition - Wikipedia

    en.wikipedia.org/wiki/Time–temperature...

    The time–temperature superposition principle is a concept in polymer physics and in the physics of glass-forming liquids. [ 1 ] [ 2 ] [ 3 ] This superposition principle is used to determine temperature-dependent mechanical properties of linear viscoelastic materials from known properties at a reference temperature.

  8. Coulomb's law - Wikipedia

    en.wikipedia.org/wiki/Coulomb's_law

    However, Gauss's law can be proven from Coulomb's law if it is assumed, in addition, that the electric field obeys the superposition principle. The superposition principle states that the resulting field is the vector sum of fields generated by each particle (or the integral, if the charges are distributed smoothly in space).
