"Ripples of Wisdom" is a beautiful metaphor that can be applied to the essence of a good teacher and the art of teaching itself. Imagine dropping a pebble into a calm pond. As it breaks the surface tension, it creates a series of ripples that expand outward, touching everything in their path. Similarly. a good teacher's wisdom and guidance can have a profound and far-reaching impact, spreading outwards like those ripples in the pond. This metaphor echoes in my ears when I think of Prof. Selva Rathinam. Just as the pebble is the catalyst for the ripples, Prof. Selva Rathinam, as a teacher, provided knowledge, insights, and guidance to his students, initiating a learning process. As the pebble dropped into a pond, he initiated a ripple effect by sharing knowledge, insights, and experiences with his students.
