Terminological inexactitude Terminological inexactitude Terminological inexactitude is a phrase introduced in 1906 by British politician Winston Churchill. Today, it is used as a euphemism or circumlocution meaning a lie or untruth. Churchill first used the phrase following the 1906 election. Speaking in the House of Commons on 22 February 1906 as Under-Secretary of the Colonial Office, he had occasion to repeat what he had said during the campaign. When asked that day whether the Government was condoning slavery of Chinese labourers in the Transvaal, Churchill replied: It has been used as a euphemism for a lie in the House of Commons, as
Representation of a Lie group map into the group of unitary operators. If "G" is a compact Lie group, every finite-dimensional representation is equivalent to a unitary one. Each representation of a Lie group "G" gives rise to a representation of its Lie algebra; this correspondence is discussed in detail in subsequent sections. See representation of Lie algebras for the Lie algebra theory. In quantum mechanics, the time-independent Schrödinger equation equation, formula_28 plays an important role. In the three-dimensional case, if formula_29 has rotational symmetry, then the space formula_30 of solutions to formula_28 will be invariant under the action of SO(3). Thus, formula_30 will—for each
