physics

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.

chemistry

Chemistry (from Egyptian kēme (chem), meaning “earth”) is the science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Modern chemistry evolved out of alchemy following the chemical revolution (1773).

unix

 

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.
