  2. Population balance equation - Wikipedia

    en.wikipedia.org/wiki/Population_balance_equation

    Consider the average number of particles with particle properties denoted by a particle state vector (x,r) (where x corresponds to particle properties like size, density, etc. also known as internal coordinates and, r corresponds to spatial position or external coordinates) dispersed in a continuous phase defined by a phase vector Y(r,t) (which again is a function of all such vectors which ...

  3. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

    Mosaic "Sacrifice of Isaac" – Basilica of San Vitale (547 AD) The Sacrifice of Isaac by Caravaggio (1603), in the Baroque tenebrist manner The Binding of Isaac (Hebrew: עֲקֵידַת יִצְחַק ‎, romanized: ʿAqēḏaṯ Yīṣḥaq), or simply "The Binding" (הָעֲקֵידָה ‎, hāʿAqēḏā), is a story from chapter 22 of the Book of Genesis in the Hebrew Bible.

  5. Close-packing of equal spheres - Wikipedia

    en.wikipedia.org/wiki/Close-packing_of_equal_spheres

    [1] [2] Highest density is known only for 1, 2, 3, 8, and 24 dimensions. [3] Many crystal structures are based on a close-packing of a single kind of atom, or a close-packing of large ions with smaller ions filling the spaces between them. The cubic and hexagonal arrangements are very close to one another in energy, and it may be difficult to ...

  6. Hydrostatic equilibrium - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_equilibrium

    Diagram of a newly formed planet in a state of hydrostatic equilibrium. In fluid mechanics, hydrostatic equilibrium (hydrostatic balance, hydrostasy) is the condition of a fluid or plastic solid at rest, which occurs when external forces, such as gravity, are balanced by a pressure-gradient force. [1]

  7. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    For example, in the reaction CH 4 + 2 O 2 → CO 2 + 2 H 2 O, the stoichiometric number of CH 4 is −1, the stoichiometric number of O 2 is −2, for CO 2 it would be +1 and for H 2 O it is +2. In more technically precise terms, the stoichiometric number in a chemical reaction system of the i -th component is defined as

  8. Equilibrium thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_thermodynamics

    Equilibrium Thermodynamics is the systematic study of transformations of matter and energy in systems in terms of a concept called thermodynamic equilibrium.The word equilibrium implies a state of balance.

  9. Isaac Newton's occult studies - Wikipedia

    en.wikipedia.org/wiki/Isaac_Newton's_occult_studies

    [2] Much of what are known as Isaac Newton's occult studies can largely be attributed to his study of alchemy . [ 3 ] From a young age, Newton was deeply interested in all forms of natural sciences and materials science , an interest which would ultimately lead to some of his better-known contributions to science.
