In view of the preceding it becomes quite obvious why many earlier efforts to concoct Computing Science Curricula at our universities have been such dismal failures. They were just cocktails! For lack of other ingredients, they tried to combine scraps of knowledge from the most diverse fields that seemed to have some relation to the phenomenon Computer. That the ingredients of the cocktail did not mix into a coherent whole, is not surprising; that the cocktail did not taste too well, is not surprising either.
