Proper velocity the traveling object. It equals the object's momentum p divided by its rest mass "m", and is made up of the space-like components of the object's four-vector velocity. William Shurcliff's monograph mentioned its early use in the Sears and Brehme text. Fraundorf has explored its pedagogical value while Ungar, Baylis and Hestenes have examined its relevance from group theory and geometric algebra perspectives. Proper velocity is sometimes referred to as celerity. Unlike the more familiar coordinate velocity v, proper velocity is synchrony-free (does not require synchronized clocks) and is useful for describing both super-relativistic and sub-relativistic motion. Like coordinate velocity
Landscape of the Body Landscape of the Body Landscape of the Body is a two-act play by John Guare, first performed in 1977. The play is episodic and non-linear, as it travels back and forth in time. The plot centers on a woman named Betty, whose son, Bert, was recently murdered and decapitated in lower Manhattan. The location of the first and last scenes are the same. They take place on a boat, with Betty, who throws bottles filled with notes overboard, and an absurdly disguised Detective Holahan. Initially, Holahan accuses Betty of killing her son, but Betty insists this is not true. The
