The game is very interesting. There is a clear learning experience involved which depends exclusively on Newton&#8217;s second law for linear motion. As a result of Pong, the player can gain a deep intuitive understanding of the simplest Newtonian physics &#8211; a better understanding even than that provided by billiards, where the collisions are far from perfectly elastic and where the spinning of the pool balls interposes more complicated physics.<\/p>\n<p><!--more-->This sort of information gathering is precisely what we call play. And the important function of play is thus revealed: it permits us to gain, without any particular future application in mind, a holistic understanding of the world, which is both a complement of and a preparation for later analytical activities.
