A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU). The IC is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored

In American cinema, Blaxploitation is the film subgenre of action movie derived from the exploitation film genre that began in the 1960s and flourished throughout the early to mid 1970s, consequent to the combined cultural momentum of the black civil rights movement and the black power movement, political and sociological circumstances that facilitated black artists reclaiming their power of the representation of the black ethnic identity in the arts. The term blaxploitation is a portmanteau of the words Black and exploitation, coined by Junius Griffin, president of the Beverly Hills–Hollywood

An ecomuseum is a museum focused on the identity of a place, largely based on local participation and aiming to enhance the welfare and development of local communities. Ecomuseums originated in France, the concept being developed by Georges Henri Rivière and Hugues de Varine, who coined the term ‘ecomusée’ in 1971. The term "éco" is a shortened form for "écologie", but it refers especially to a new idea of holistic interpretation of cultural heritage, in opposition to the focus on specific items and objects, performed by traditional museums.

Yerkish is an artificial language developed for use by non-human primates. It employs a keyboard whose keys contain lexigrams, symbols corresponding to objects or ideas.

Reptation is the thermal motion of very long linear macromolecules in entangled polymer melts or concentrated polymer solutions. Derived from the word reptile, reptation suggests the movement of entangled polymer chains as being analogous to snakes slithering through one another. Pierre-Gilles de Gennes introduced (and named) the concept of reptation into polymer physics in 1971 to explain the dependence of the mobility of a macromolecule on its length. Reptation is used as a mechanism to explain viscous flow in an amorphous polymer. Sam Edwards and Masao Doi later refined reptation theory.
