  2. Physical property - Wikipedia

    en.wikipedia.org/wiki/Physical_property

    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.

  3. List of materials properties - Wikipedia

    en.wikipedia.org/wiki/List_of_materials_properties

    A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.

  4. Property (programming) - Wikipedia

    en.wikipedia.org/wiki/Property_(programming)

    Property (programming) A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method. The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to ' getter ' and ' setter ...

  5. Chemical property - Wikipedia

    en.wikipedia.org/wiki/Chemical_property

    Chemical property. A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. [1] Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance ...

  6. Intrinsic and extrinsic properties - Wikipedia

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

    In science and engineering, an intrinsic property is a property of a specified subject that exists itself or within the subject. An extrinsic property is not essential or inherent to the subject that is being characterized. For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that depends on ...

  7. Intensive and extensive properties - Wikipedia

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

    Extensive properties. An extensive property is a physical quantity whose value is proportional to the size of the system it describes, [8] or to the quantity of matter in the system. For example, the mass of a sample is an extensive quantity; it depends on the amount of substance. The related intensive quantity is the density which is ...

  8. Emergence - Wikipedia

    en.wikipedia.org/wiki/Emergence

    e. In philosophy, systems theory, science, and art, emergence occurs when a complex entity has properties or behaviors that its parts do not have on their own, and emerge only when they interact in a wider whole. Emergence plays a central role in theories of integrative levels and of complex systems.

  9. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    As shown rigorously by Noether's theorem, the conservation of energy is a mathematical consequence of translational symmetry of time, a property of most phenomena below the cosmic scale that makes them independent of their locations on the time coordinate. Put differently, yesterday, today, and tomorrow are physically indistinguishable.
