The Great Aha!!
It cannot be expressed how happy a teacher feel when a student produces or explains something that has not appeared in the formal classes.
The reason for this feeling of great satisfaction is the fact that the ultimate goal of a University education is to produce professionals who can learn on their own & who can continue to explore new knowledge thus they will be at the frontiers of their profession.
On second thought, the ultimate goal is not only a professional who can continue to learn. The real ultimate goal is to be able to ask the right questions that expand the frontiers of knowledge. Those are the people that have contributed to the advancement of science and they are the ones who experience the great Aha!!!
They also listen to music and eat chicken like everybody else.
