In this speech, Dr. APJ Abdul Kalam highlights the transformative experience of sea travel and shares a fascinating anecdote about the Nobel Prize-winning scientist Sir CV Raman. He explains how Raman's curiosity about the blue horizon where the sea and sky meet led to the discovery of the inelastic scattering of photon in light, and ultimately earned him the prestigious Nobel Prize. Kalam encourages us to embrace the wonders of sea travel and to keep asking questions and exploring the mysteries of the world around us.
