1. Material particles

We shall start with the simplest case, throwing tennis balls against a wall in which two long and narrow cuts have been carved. It will be apparent that in this case no particular knowledge of physics concepts is needed to predict and explain the result of the experiment. The physics of material particles is in a sense “easier” that the physics of waves or of quantum mechanics, since generally (albeit not always!) it is easier to reconcile with common intuition.
