Food, like anything else, lives in the physical world and obeys the laws of physics. When you whisk together some oil and a little bit of lemon juice - or, in other words, make mayonnaise - you are using the principles of physics and chemistry. Understanding how those principles affect cooking lets you cook better.

We're more familiar with what economists call an English auction - prices start low and rise as people bid. However, there is also the Dutch auction, where prices start high and go lower until somebody bites. Movies are sold to the audience via a very slow Dutch auction, where each phase between price drops can last weeks or months.
