After completely blowing an ambitious summer schedule of weekly episodes, Patrick and Greg sit poolside and shoot the breeze about the fascinating history of quantitative methods.

This discussion sets the stage nicely for a future summer episode, at least in theory given how long it took to get this one out. Happy Summer! Stay ...
