First, Adam digs into headlines about daredevil "Mad Mike" Hughes who died in a homemade rocket accident intended to “prove” the Earth is flat. One of our two favourite Stuarts, Dr. Stu Robbins, brings us a relatively compelling look into the precession of Mercury. Finally, Darren brings us an interesting overview of revealed preferences, a major theory of consumption behaviour.
