ABSTRACT
Students of economics generally realize that Keynes ' s General Theory reduces "classical" economics to a special case of full employment equilibrium which is a limiting point of the possible position of equilibrium. 1 In physics, Einstein' s introduction in his special theory of relativity of a new universal constant, c (the constant speed of light) , also reduces classical physics to a spe cial case when c is given a value of infinity ( oo ). The relationship between classical mechanics and quantum mechanics is similar to the above-mentioned two cases. If Planck' s constant, h, is given a value of zero, all the distinctions between classical me chanics and quantum mechanics would become fuzzy.
