In 1963, American mathematician and meteorologist Edward Lorenz observed the strange attractor, or the understanding that in complex systems any starting point will have a sensitive dependence on initial conditions. He later described this founding principle of chaos theory as the butterfly effect, in which a very small change in initial conditions leads to significantly altered outcomes If history were started from a single point and run again and again, each time a different future would unfold. These futures may be similar, even eerily close to other futures, but each would be infinitely different. Here are told the stories of 100 such strange futures initiated in the year 2016, at the age of 16 when most first become aware of the wider world and their tiny butterfly like existence in such a huge and stormy life.
