Suprakash C. Roy, commonly referred to as S.C. Roy in his professional life, moved with ease from one research area to another. At an international level, he played many distinctive roles - a scientist, an editor, author, and mentor to many of his younger colleagues. This book is the story of a person who came from a very modest family but rose to an unprecedented height by his courage and determination, setting an example to follow for our younger generation of less privileged students.
