Sometimes its very easy, and its the reason why people 
don't wear hats anymore. According to this video
people don't war hats anymore because we have

central heating in the office, heading in the car,
and heating at home:

Why Did Men Stop Wearing Hats?

Now whats the relatively reliable prediction, that
is needed for these climat systems?

a) If I have fire = 1 in the boiler, then the
  temperature of the water will go up

b) If I have fire = 0 in the boiler, then the
  tenperature of the water will go down

In mathematical terms, more or less, where
this time the dependent variable y is not
a location but the temperature of the water:

y' = (2*fire-1)

Maybe dull people like Dan Christensen have
never though about the fact that calculus, and 
the concept of "rate" in calculus typically

deals with the future?
