It is said that evolution occurred over millions of years leading to a lot of gradual changes. But if one were to map the changes that have occurred over the last hundred years, it has changed the world in a way that is beyond imagination. It is difficult to grapple with the changes that have occurred even in the last five years. From relativity theory to discover of the milky way and a man setting foot on the moon; discoveries in the field of biology and medicine, inventing drugs for previously incurable diseases; the invention of motorcycles to hyperloop, telephones to wireless technology and cloud computing, drones & even self-driving cars. The list goes on and on as inventions and discoveries are taken place even as we speak.
