Issue No.04 - July/August (1972 vol.5)
Since the beginning of time, man has sought knowledge to explain phenomena and new techniques to simplify his tasks. In these quests, he has ultimately dealt with four basic questions: 1) What is the problem? 2) How may the problem be solved? 3) How applicable is a given solution? and 4) Why does a solution yield a particular set of results? Technological evolution has occurred because man has been motivated to ask and resolve such questions.
