A theorem postulating that all black hole solutions of the Einstein-Maxwell equations in general relativity can be completely characterized by only three externally observable classical parameters: mass, electric charge, and angular momentum.

(physics) A discredited scientific theory, once considered an alternative to special relativity, proposing that light is emitted at speed c relative to its source instead of applying the invariance postulate.

(economics) The idea that the burdens of taxation "stick" to those taxed directly instead of spreading through the economy.

(politics, historical) Synonym of domino effect

(logic) A procedure for "discharging" assumptions from an inference, causing them to become antecedents of the conclusion; or vice versa. Symbolically, the conversion of an inference of the form P,A⊢C to an inference of the form P⊢A→C or vice versa, where ⊢ is the turnstile symbol. The validity of the procedure is a metatheorem of the given logical theory.

(logic) The following theorem of Boolean algebra: XY+X'Z+YZ=XY+X'Z where YZ, the algebraically redundant term, is called the "consensus term", or its dual form (X+Y)(X'+Z)(Y+Z)=(X+Y)(X'+Z), in which case Y+Z is the consensus term. (Note: X+Y,X'+Z⊢Y+Z is an example of the resolution inference rule (replacing the + with ∨ and the prime with prefix ¬ might make this more evident).)

(botany) Any of the genus Theobroma of small trees.

plural of theobroma

(chemistry) An acid extracted from cocoa butter, peanut oil, etc. as a white waxy crystalline substance.

(mathematical analysis) A theorem which states that for any subset S of an n-dimensional Euclidean space, S is compact if and only if it is both closed and bounded.
