钱学森的美国学生在他死后写的文章:“With appreciation of Dr. Tsien’s fame and the respect held for him, it is easy to understand the great interest generated when he announced a new course in what he called engineering cybernetics, “a new branch of engineering science.” This was possibly one of the first courses in control theory in the United States.” 【"工程控制论" 是工程科学的新分支。(钱学森新开的"工程控制论" 课可能是在美国开的第一门控制理论课。】
