<human>:  Who discovered the inverse square law?
<bot>: The inverse square law was discovered by Isaac Newton. It is the relationship between the strength of a force and the distance between the objects involved. The law states that the force exerted by one object on another is inversely proportional to the square of the distance between the objects. For example, if two people are holding hands and you pull on their hands, the force of the pull is inversely proportional to the square of the distance between them.
