Unix (officially trademarked as UNIX, sometimes also written as Unix with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Today’s Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations.

Physics (Greek: physis – φύσις meaning “nature”) is the natural science which examines basic concepts such as energy, force, and spacetime and all that derives from these, such as mass, charge, matter and its motion.Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy.
