Abstract: I would prefer to start with this wonderful quote said by Albert Einstein Imagination is more important than knowledge. Yes ofcourse; action is the byproduct of our thought or imagination comes first than action. Lets look back into history, from the very past mankind is getting benefitted from Science & technology,housands of great inventions by prominent heroes of the earth, and society has given them special honor and privilege. They have truly changed the face of life, but that was the era of few scientists who contributed individually.
