This is the first part of a discussion about chapter 3 of "The Fabric of Reality". It is about...problem solving with a significant focus on science and how scientific theories are generated. It contains criticism of the prevailing "justificationist" and "inductivist" notions. I see it as a good companion to (perhaps an introduction to) my episode "The Aim of Science" which I would consider a little more "heavy". This was wide ranging and a lot of fun to produce!
