1. It should be mentioned that these particular mathematical formulas were found by trial and error: the empirical results produced by these formulas seem to be the most adequate for the description of the real world; other formulas we have tried — such as that with qualified manpower (total stock of scientists and engineers) instead of population — do not give results which correspond to common sense judgement. It should also be mentioned that these formulas are a somewhat modified form of what V. MATEJIC (cf. note 6) proposed in his paper delivered at a workshop in Berlin in 1983.
