George Bailey Brayton (1830–1892) was an American mechanical engineer and inventor. He was noted for introducing the constant pressure engine that is the basis for the gas turbine , and which is now referred to as the Brayton cycle .
The Brayton cycle, also known as the Joule cycle, is a thermodynamic cycle that describes the operation of certain heat engines that have air or some other gas as their working fluid. It is characterized by isentropic compression and expansion, and isobaric heat addition and rejection, though practical engines have adiabatic rather than ...

George Brayton invented the first commercial liquid-fueled internal combustion engine in 1872. In 1876, Nicolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-stroke cycle engine. In 1879, Karl Benz patented a reliable two-stroke gas engine.
Human behavior is the potential and expressed capacity (mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Behavior is driven by genetic and environmental factors that affect an individual.
Sir Dugald Clerk's two-cycle engine. Clerk began work on his own engine designs in October 1878 after modifying a Brayton engine with a spark plug. Brayton engines (called "Ready Motors" were made from 1872 to 1876) and were one of the first engines to successfully use compression and combust fuel in the cylinder.
Social cycle theories are among the earliest social theories in sociology.Unlike the theory of social evolutionism, which views the evolution of society and human history as progressing in some new, unique direction(s), sociological cycle theory argues that events and stages of society and history generally repeat themselves in cycles.
To classify what should be included in modern human behavior, it is necessary to define behaviors that are universal among living human groups. Some examples of these human universals are abstract thought , planning, trade, cooperative labor, body decoration, and the control and use of fire.
