In this book, Wells describes nuclear warfare and begins the descriptions of a possible future. He named uranium, "Carolinum" and talked about a chain reaction that would leave radiation behind so that nothing would survive afterwards, even if they did escape from the weapon itself. Dr. Szilard, the man who came up with the idea of splitting the atom with a nuetron, did so after reading, "The World Set Free". I say, NO KIDDING! Wells lays the idea right out in front of the world's face, laughing! It then goes on to describe future events that have occured, though in different times, and some which have yet to occur. He spoke of Carolinum (uranium), the atomic theory and its increadible source of power. He spoke of robotics and computers replacing people in the work place. This is where it all started folks. AND THIS IS JUST IN THE FIRST 100 PAGES! Trust me... it gets better :) If you wish yo know more on the theory and the bombs' construction, I refer you to Richard Rhodes. If you want to know the mind and the story that began this whole deal, read this book!!!!
