The increase in the use of computers in pharmaceutics was largely a consequence of the increase in computer power, which had been exponential over the past 40 years, Professor ROWE said. Memory capacity had increased by a factor of 10~9 over this period, and the operational speed had increased by the same amount. The cost per arithmetical operation had correspondingly decreased by the same factor, and there seemed to be no end in sight to this continual improvement. One result was that computational tasks that were unthinkable as recently as 10 years ago were now an everyday occurrence.
