There is a difference between science and technology. Science is a method of answering theoretical questions, technology is a method of solving practical problems (and sometimes creating new problems out of the "solutions"). Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relalionships; technology has to do with tools, techniques, and procedures for implementing the findings of science. Another distinction between science and technology has to do with the progress in each.
Progress in science excludes the human factor. And this is justly so. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay heed to their own or other people’s likes or dislikes or to popular ideas about the fitness of things.
