We present a brief survey of the development of nuclear physics towards
relativistic quark physics. This is followed by a thorough discussion of the
quest for the observation of the dissolution of nuclear matter into the
deconfined quark matter (QGP) in relativistic nuclear collisions. Use of
strange particle signatures in search for QGP is emphasized.Comment: 50 pages, including 8 figures; Presented in August 1997 at the 5th
