  2. Intrinsic and extrinsic properties - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_and_extrinsic...

    In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. [1]

  3. Chirality - Wikipedia

    en.wikipedia.org/wiki/Chirality

    Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin. Although both chirality and helicity can have left-handed or right-handed properties, only in the massless case are they identical. [ 5 ]

  4. Chiral media - Wikipedia

    en.wikipedia.org/wiki/Chiral_media

    Extrinsic means that the chirality is a consequence of the arrangement of different components, rather than an intrinsic property of the components themself. For example, the propagation direction of a beam of light through an achiral crystal (or metamaterial) can form an experimental arrangement that is different from its mirror image.

  5. Permeation - Wikipedia

    en.wikipedia.org/wiki/Permeation

    In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid.It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. [1]

  6. Physical property - Wikipedia

    en.wikipedia.org/wiki/Physical_property

    A physical property is any property of a physical system that is measurable. [1] The changes in the physical properties of a system can be used to describe its changes between momentary states. A quantifiable physical property is called physical quantity. Measurable physical quantities are often referred to as observables.

    en.wikipedia.org/wiki/Glossary_of_elementary...

    Fermions are particles with half-integer spin (s = 1/2, 3/2, 5/2, ... ). Like bosons, they can be elementary or composite particles. Like bosons, they can be elementary or composite particles. There are two types of elementary fermions: quarks and leptons , which are the main constituents of ordinary matter.

  8. Intensive and extensive properties - Wikipedia

    en.wikipedia.org/wiki/Intensive_and_extensive...

    [1] [2] According to International Union of Pure and Applied Chemistry (IUPAC), an intensive property or intensive quantity is one whose magnitude is independent of the size of the system. [3] An intensive property is not necessarily homogeneously distributed in space; it can vary from place to place in a body of matter and radiation.

  9. Stern–Gerlach experiment - Wikipedia

    en.wikipedia.org/wiki/Stern–Gerlach_experiment

    The results show that particles possess an intrinsic angular momentum that is closely analogous to the angular momentum of a classically spinning object, but that takes only certain quantized values. Another important result is that only one component of a particle's spin can be measured at one time, meaning that the measurement of the spin ...
