The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is subtracted from the desired value to create the error signal, which is amplified by the controller. Extensive use is usually made of a diagrammatic style known as the block diagram. The transfer function, also known as the system function or network function, is a mathematical representation of the relation between the input and output based on the differential equations describing the system. Although a major application of control theory is in control systems engineering, which deals with the design of process control systems for industry, other applications range far beyond this.
As the general theory of feedback systems, control theory is useful wherever feedback occurs; a few examples are in physiology, electronics, climate modeling, machine design, ecosystems, navigation, neural networks, predator-prey interaction, and gene expression.

Jean-Jacques Rousseau (/ruːˈsoʊ/;[1] French: [ʒɑ̃ʒak ʁuso]; 28 June 1712 – 2 July 1778) was a Genevan philosopher, writer, and composer of the 18th century.
His political philosophy influenced the French Revolution as well as the overall development of modern political, sociological, and educational thought. Biography[edit] Youth[edit] Rousseau was born in Geneva, which was at the time a city-state and a Protestant associate of the Swiss Confederacy. Since 1536, Geneva had been a Huguenot republic and the seat of Calvinism. Five generations before Rousseau, his ancestor Didier, a bookseller who may have published Protestant tracts, had escaped persecution from French Catholics by fleeing to Geneva in 1549, where he became a wine merchant.[5] Rousseau was proud that his family, of the moyen order (or middle-class), had voting rights in the city. Geneva, in theory, was governed democratically by its male voting "citizens". The house where Rousseau was born at number 40, Grand-Rue.
