  2. Pseudovector - Wikipedia

    en.wikipedia.org/wiki/Pseudovector

    [1] In physics and mathematics, a pseudovector (or axial vector) [2] is a quantity that behaves like a vector in many situations, but its direction does not conform when the object is rigidly transformed by rotation, translation, reflection, etc. This can also happen when the orientation of the space is changed.

  3. Metamorphoses in Greek mythology - Wikipedia

    en.wikipedia.org/wiki/Metamorphoses_in_Greek...

    In ancient Greece, the surviving Greek mythology features a wide collection of myths where the subjects are physically transformed, usually through either divine intervention or sorcery and spells. [1] Similar themes of physical transformation are found in all types of mythologies, folklore, and visual arts around the world, including those of ...

  4. Girsanov theorem - Wikipedia

    en.wikipedia.org/wiki/Girsanov_theorem

    The theorem is especially important in the theory of financial mathematics as it explains how to convert from the physical measure, which describes the probability that an underlying instrument (such as a share price or interest rate) will take a particular value or values, to the risk-neutral measure which is a very useful tool for evaluating ...

  5. Active and passive transformation - Wikipedia

    en.wikipedia.org/wiki/Active_and_passive...

    Geometric transformations can be distinguished into two types: active or alibi transformations which change the physical position of a set of points relative to a fixed frame of reference or coordinate system (alibi meaning "being somewhere else at the same time"); and passive or alias transformations which leave points fixed but change the ...

  6. Derivations of the Lorentz transformations - Wikipedia

    en.wikipedia.org/wiki/Derivations_of_the_Lorentz...

    In the fundamental branches of modern physics, namely general relativity and its widely applicable subset special relativity, as well as relativistic quantum mechanics and relativistic quantum field theory, the Lorentz transformation is the transformation rule under which all four-vectors and tensors containing physical quantities transform from one frame of reference to another.

  7. Covariant transformation - Wikipedia

    en.wikipedia.org/wiki/Covariant_transformation

    The explicit form of a covariant transformation is best introduced with the transformation properties of the derivative of a function. Consider a scalar function f (like the temperature at a location in a space) defined on a set of points p, identifiable in a given coordinate system , =,, … (such a collection is called a manifold).

  8. Conjugate variables - Wikipedia

    en.wikipedia.org/wiki/Conjugate_variables

    Conjugate variables are pairs of variables mathematically defined in such a way that they become Fourier transform duals, [1] [2] or more generally are related through Pontryagin duality. The duality relations lead naturally to an uncertainty relation—in physics called the Heisenberg uncertainty principle—between them.

  9. Metamorphosis - Wikipedia

    en.wikipedia.org/wiki/Metamorphosis

    A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
