also referred to as telekinesis (Greek τῆλε + κίνησις, literally "distant-movement") with respect to strictly describing mental movement or motion of solid matter, abbreviated as PK and TK respectively, is a term coined by publisher Henry Holt to refer to the direct influence of mind on a physical system that cannot be entirely accounted for by the mediation of any known physical energy. Examples of psychokinesis could include distorting or moving an object, and influencing the output of a random number generator.
