Using a ruler to measure the length of a stick is an example of extending the sense of sight by using an instrument

Humans possess five major sense organs namely: tongue, eyes, nose, skin and ear. Each of these senses serve different purposes, however, scientists do not entirely use them for scientific measurements. Scientists make use of instruments to extend their senses, which they use for perception only. For example, a ruler is used to measure the length of a stick in order to extend our knowledge of the stick, which was gained by sighting the object. Therefore, using a ruler to measure the length of a stick is an example of extending the sense of sight by using an instrument.
