In 1947, Dr. Chandrasekhar was scheduled to teach an advanced seminar in astrophysics at the University of Chicago. At the time, he was living in Wisconsin, doing research at the Yerkes astronomical observatory. He faced an in-the-dead-of-winter, twice-a-week, one-hundred-mile commute to teach the class, but he nonetheless agreed enthusiastically.
Registration for the advanced seminar, however, fell far below expectations. In fact, only two students signed up for the class. Other faculty members expected Dr. Chandrasekhar to cancel the course so as to not waste his valuable time. He determined, however, to continue with the course and give his very best to the two students registered.
Those students, Chen Ning Yang and Tsung-Dao Lee, made his effort worthwhile. Ten years later, in 1957, they both won the Nobel prize for physics. Dr. Chandrasekhar later won that same award in 1983.
Ends and means are not meant to exist in conflict. Good means to good ends are what God challenges us to find and to do, regardless of the personal cost, the effort required or a lack of public acclaim. The best pursuit of the best ideals is what makes for integrity.
