2. List of states of matter - Wikipedia

   en.wikipedia.org/wiki/List_of_states_of_matter

   Time crystals: A state of matter where an object can have movement even at its lowest energy state. Hidden states of matter: Phases that are unattainable or do not exist in thermal equilibrium, but can be induced e.g. by photoexcitation. Microphase separation: Constituent units forming diverse phases while also keeping united.

3. Thermodynamics - Wikipedia

   en.wikipedia.org/wiki/Thermodynamics

   Matter or energy that pass across the boundary so as to effect a change in the internal energy of the system need to be accounted for in the energy balance equation. The volume contained by the walls can be the region surrounding a single atom resonating energy, such as Max Planck defined in 1900; it can be a body of steam or air in a steam ...

4. Laws of thermodynamics - Wikipedia

   en.wikipedia.org/wiki/Laws_of_thermodynamics

   When matter is transferred into a system, the internal energy and potential energy associated with it are transferred into the new combined system. ( u Δ M ) i n = Δ U s y s t e m {\displaystyle \left(u\,\Delta M\right)_{\rm {in}}=\Delta U_{\rm {system}}} where u denotes the internal energy per unit mass of the transferred matter, as measured ...

5. Spaces of test functions and distributions - Wikipedia

   en.wikipedia.org/wiki/Spaces_of_test_functions...

   No matter what dual topology is placed on ′ (), [note 13] a sequence of distributions converges in this topology if and only if it converges pointwise (although this need not be true of a net). No matter which topology is chosen, D ′ ( U ) {\displaystyle {\mathcal {D}}^{\prime }(U)} will be a non- metrizable , locally convex topological ...

6. Plasma (physics) - Wikipedia

   en.wikipedia.org/wiki/Plasma_(physics)

   The fourth state of matter Plasma is called the fourth state of matter after solid , liquid , and gas . [ 16 ] [ 17 ] [ 18 ] It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.

7. Periodic table - Wikipedia

   en.wikipedia.org/wiki/Periodic_table

   The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.

8. Four-dimensional space - Wikipedia

   en.wikipedia.org/wiki/Four-dimensional_space

   Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

9. Etheric plane - Wikipedia

   en.wikipedia.org/wiki/Etheric_plane

   Similarly, according to the Rosicrucian writings of American occultist and mystic Max Heindel [5] there is – in addition to the solids, liquids, and gases which compose the Chemical Region of the Physical World – a finer grade of matter called ether that permeates the atomic structure of the earth and its atmosphere.
