The FOIL method is a special case of a more general method for multiplying algebraic expressions using the distributive law. The word FOIL was originally intended solely as a mnemonic for high-school students learning algebra. The term appears in William Betz's 1929 text Algebra for Today, where he states: [2]
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.
The term "FOIL rule" is rarely used, "FOIL method" is an order of magnitude more common. I suggest moving the article accordingly. --Vaughan Pratt 19:04, 6 September 2009 (UTC) A quick Google search confirmed this. I have moved the article. Jim 22:08, 26 September 2009 (UTC)
A mnemonic to remember which way to turn common (right-hand thread) screws and nuts, including light bulbs, is "Righty-tighty, Lefty-loosey"; another is "Right on, Left off".

Suppose for example one desires to compute the derivative of the internal energy. The following procedure should be considered: The following procedure should be considered: Place oneself in the thermodynamic potential of interest, namely ( G {\displaystyle G} , H {\displaystyle H} , U {\displaystyle U} , F {\displaystyle F} ).

For example the first results from a cloud chamber, by C.T.R. Wilson shows alpha particle scattering and also appeared in 1911. [ 24 ] [ 9 ] : 302 Over time, particle scattering became a major aspect of theoretical and experimental physics; [ 25 ] : 443 Rutherford's concept of a "cross-section" now dominates the descriptions of experimental ...
