The joy of participating with my team in these nuclear tests and proving to the world that India can make it, that we are no longer a developing nation but one of them. It made me feel very proud as an Indian. The fact that we have now developed for Agni a re-entry structure, for which we have developed this new material. A Very light material called carbon-carbon. One day an orthopedic surgeon from Nizam Institute of Medical Sciences visited my laboratory. He lifted the material and found it so light that he took me to his hospital and showed me his patients. There were these little girls and boys with heavy metallic calipers weighing over three Kg. each, dragging their feet around. He said to me: Please remove the pain of my patients. In three weeks, we made these Floor reaction Orthosis 300-gram calipers and took them to the orthopedic center. The children didn’t believe their eyes. From dragging around a three kg. load on their legs, they could now move around! Their parents had tears in their eyes.
