: The '''reaction time''' of a human can be measured using a variety of experiments where a random event happens and the subject has to respond as quickly as possible. [http://www.bbc.co.uk/science/humanbody/sleep/sheep/ Test your reaction time here]
: Typical '''reaction time''' for a [[human]] is around 0.2 [[second]]s.
===Method for Testing Reaction Time===
#The subject places the forearm on a table with the hand hanging over the edge.
#A second person holds a metre ruler from the very top and allow it to hang from their fingers with the 0cm mark level with the top of the subject's hand.
#The subject holds their index finger and thumb apart allowing the ruler to fall between them.
#The second person gives no warning before dropping the ruler.
#The subject catches the ruler as quickly as possible between the thumb and index finger.
#Record the length of ruler that has passed through the subject's hand in metres.
#Convert the distance into reaction time with the following formula:
: <math>t={{\sqrt{0.2 \times d}}}</math>
: Where t is the time and d is the distance the ruler has travelled.
