Science has evolved from the playground of aristocrats to the profession of artisans. From the theories of Galen to genetic engineering. It provides the most comprehensive description we have of why rain falls, why the sun rises and how people live and die. For the more commonplace, it informs how we brush our teeth, the food we choose to eat and how we build our homes. But despite this enormous reach into our lives, what science is and what it does is often obscure, uncertain and difficult to understand.
Using biology and medicine as a background, we’ll discuss what science is (and what it isn’t), whether it is hard to do and teach, and how it can be used (and misused).
