Andre Koch Torres Assis is a professor of Physics at the University of Campinas in Brazil, who has been studying the history of electricity and electrodynamics for more than thirty years. As part of his research, he has assembled put together a collection of experiments that demonstrate some of the earliest experiences that natural philosophers had with electricity - and which show how poorly understood these phenomena still are today, more than two hundred years after they were first observed.
