Mercury (toy manufacturer) Marklin, the company was started in 1932, by Attilio Clemente and Antonio Cravero, but its first toy was a gun produced about 1939 (Batazzi et al 1974; Force 1992, 5; History of Mercury 2013; Ralston 2009, 62). The company first began making toy cars just after World War II, so is one of the earliest diecast model makers preceding Corgi and many others and it was the earliest producer in Italy (Richardson 1999, 134). In Italy there was little competition for Mercury through most of the 1950s (Force 1992, 5). Early cars were more Tootsietoy-like with simple cast bodies, wheels
Spekkens toy model An analysis of the system from the point of view of categorical quantum mechanics has also proved insightful Currently, there is work being done to reproduce quantum formalism from information-theoretic axioms. Although the model itself differs in many respects from quantum theory, it reproduces a number of effects considered to be overwhelmingly quantum. As such, the underlying principle, that quantum states are states of incomplete knowledge, may offer some hints as to how to proceed in this manner and may lend hope to those pursuing this goal. Spekkens toy model The Spekkens toy model is a conceptually simple toy model
