Wikipedia has got a nice differential equation (Newton's law of cooling) which states that the rate of heating = [stuff]*(surrounding temperature - temperature of object). If the temperature of the object is greater than the surrounding temperature, the rate of heating will be negative (cooling) and the hotter the object is, the more negative the rate will be (faster cooling).

Yes, because it's digital. It's like all these patents that go method and apparatus for laundering money... ON THE INTERNET!!!one!

Well, there you go. Caffeine is what makes the brain tick, so it is obviously the father.
