seems like i've present a not very good question.

well, the background of this question goes like this.
i really know some guys work in scientific professions possess an intense ambition to achieve some great goals so as to benefit the society, hence they could accept some kind of fame or reward. if a scientist is motivated by such a goal, he would care more about the result of his work rather than the real demand in according with object principle in relevant field.
if one really like the research work he has chose to devote to, he can enjoy the process of the investigation which could cacuriosityuriocity, rather than care much about what the research would bring out. along such way, he could be more promising to go further.
