    en.wikipedia.org/wiki/Fast_multipole_method

    The fast multipole method (FMM) is a numerical technique that was developed to speed up the calculation of long-ranged forces in the n-body problem.It does this by expanding the system Green's function using a multipole expansion, which allows one to group sources that lie close together and treat them as if they are a single source.

    Ring expansion and ring contraction reactions expand or contract rings, usually in organic chemistry. The term usually refers to reactions involve making and breaking C-C bonds, [1] Diverse mechanisms lead to these kinds of reactions. The bond migration step of the pinacol type rearrangement

  8. Joule expansion - Wikipedia

    en.wikipedia.org/wiki/Joule_expansion

    The Joule expansion, in which a volume V i = V 0 is expanded to a volume V f = 2V 0 in a thermally isolated chamber. A free expansion of a gas can be achieved by moving the piston out faster than the fastest molecules in the gas.
