Is it possible that we’re not as in control as we think we are? We spend our entire teenage years convincing ourselves that we’re individuals, but when it comes to our collective behaviour is that really true? From governments to economists to red top newspapers, everyone wants to understand why society is how it is. Physicists are no exception. I recently finished reading Critical Mass by Philip Ball. Philip Ball is a chemist come physicist come science writer. From reading his book he sounds like a physicist at heart, perhaps I’m biased. The book is enormous and contains many of the things I’d like to write about here.
