Electrical engineering credited with establishing the term "electricity". He also designed the versorium: a device that detects the presence of statically charged objects. In 1762 Swedish professor Johan Carl Wilcke invented a device later named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday (the discoverer of electromagnetic
Alessandro Vespignani Alessandro Vespignani Alessandro Vespignani is an Italian-American physicist, best known for his work on complex networks, and particularly for work on the applications of network theory to the spread of disease, applications of computational epidemiology, and for studies of the topological properties of the Internet.
