a scalar quantity that changes sign when the sense of the orientation of the coordinate system is changed
Word origin
[1940–45; pseudo- + scalar]This word is first recorded in the period 1940–45. Other words that entered Englishat around the same time include: blockbuster, debrief, silkscreen, snorkel, whiteoutpseudo- is a combining form meaning “false,” “pretended,” “unreal,” used in the formationof compound words (pseudoclassic; pseudointellectual); in scientific use, pseudo- denotes close or deceptive resemblance to the following element (pseudobulb; pseudocarp), and is used sometimes in chemical names of isomers (pseudoephedrine)
