Invented by Amos Fosdyke in the late 19th century, this notation brought a rigour to the measurement of interactions between game entities which enabled Grossman and Trellis to formulate their zone boundary interaction diagrams. Extension of Fosdyke principles to more abstract concepts such as Beck's Coefficient, and even to Fosdyke codes themselves, permitted the advanced quantum token dynamic theories to be constructed. The impact of these breakthroughs still has to be fully assessed, but they would have been impossible without Fosdyke's contribution.
