 In my physics class, to analyze motion of an object, we use a ticker timer 
that places dots on a piece of paper. Knowing the time interval for these 
dots and measuring the distance between dots we can determine the speed of 
the object. Yet as humans we can quickly tell whether an object such as a 
car moving at a high speed or low speed without such equipment.  How does 
the brain do this?  Do we have some type of built-in ticker timer? What is 
the current theory on how humans detect motion?
