https://www.mdpi.com/2075-1680/8/2/53 A mathematical model is equal to a   
   physics engine which predicts future states of a system. A forward model   
   can be created for a car, but also for the motor of the car. The question   
   is, how fast is the acceleration of the motor if a certain input voltage   
   is put to the system. In a newly published paper (which has a CC-BY 4.0   
   license) this question was answered with two techniques in comparison. The   
   first one is a differential equation the second one is an outdated fuzzy   
   model. The fuzzy model didn't predicted the speed of the electric motor   
   accurate enough and this proves that uncertainty can't be modeled.
