Science has to do with discovering the facts and relationships between observable phenomena in(53)and with(54). theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the findings of science.
   Progress in science(55)the human factor. And this is justly so. Scientists, who seek to comprehend the(56)and know the truth within the highest degree of accuracy  and(57)cannot pay attention to their own or other people’s likes or dislikes or to(58)ideas about the fitness of things.

The legitimate purpose of technology is to serve people—people  in general, not merely some people; and future generations, not merely(64)who presently wish to(65)advantage for themselves. Technology must be humanistic if it is to lead to a better world.
