German Railway mathematics
As you all know (or not, I don’t know), temperature is a bit chilly right now. Since a few days the medium temperature probably is at -10 degrees. However the felt temperature is at -30 degrees at least by the time I wait on the platform. And whilst I stood there waiting, I made a sensational mathematical discovery: Train-Delay is inversely proportional to air temprature (with one premise).
Thesis:
y (cold feet) = A (Train-Delay) / x (air temperature)
Premise (and definitely a damn fact):
y is always negative (the less negative it is, the more cold are the feet).
Proof:
Today the train was delayed 14 minutes and the air temperature was at -9 degrees. As a consequence y was -1,555 and therefore I had cold feet (oh yes, very cold feet).
Other observations resulted in the following series of tests:
Two days ago the train was not delayed and the air temperatur was at -8 degrees. As a consequence y was 0 and therefore I didn’t had cold feet.
Yesterday the train was delayed 12 minutes and the air temperature was at -12 degrees. As a consequence y was -1 and therefore I had cold feet (yes, colder than today).
On a day last summer the train was delayed 5 minutes and the air temperature was at 26 degrees. As a consequence y was 0,192 and therefore I didn’t had cold feet.
On another day last summer the train was not delayed and the air temperature was at 23 degrees. As a consequence y was 0 and therefore I didn’t had cold feet.
Consequence:
As a result you can calculate the train delay on the basis of the coldness of your feet. Impressive, isn’t it?
