W. Ross Ashby Digital Archive. Ross Ashby was one of the original members of the Ratio Club, a small informal dining club of young psychologists, physiologists, mathematicians and engineers who met to discuss issues in cybernetics. The club was founded in 1949 by the neurologist John Bates and continued to meet until 1958. The title of his book "An Introduction to Cybernetics" popularised the usage of the term 'cybernetics' to refer to self-regulating systems, originally coined by Norbert Wiener in "". The book dealt primarily with homeostatic processes within living organisms, rather than in an engineering or electronic context. Earlier, in 1946, Alan
Giovanni Forni (mathematician) American Mathematical Society. Giovanni Forni (mathematician) Giovanni Forni is an Italian mathematician at the University of Maryland known for his research in dynamical systems. After graduating from the University of Bologna in 1989, he obtained his PhD in 1993 from Princeton University, under the supervision of John Mather. He was an invited speaker at the 2002 International Congress of Mathematicians in Beijing. For his work on solutions of cohomological equations for flows on surfaces, and on the Kontsevich–Zorich conjecture concerning deviation of ergodic averages, he was awarded the 2008 Michael Brin Prize in Dynamical Systems. In 2012, he became a
