Gamification Pickup and Deliver Mechanic

Dr. Boxer decides to create a game board that depicts a cell and pieces for 12 different materials that might be transported into or out of the cell. Students are assigned to teams and given the opportunity to place certain materials either in the cell or in the bloodstream (which surrounds the cell and through which these materials move around the board). He then adds a small role-playing element to the game by giving each team an identity (such as a moving company) and an objective separate...

 How Metroid Forces Players to Remember the Whole World

Whenever a Metroid player aquires a new power-up, her mind races back in time in a way not unlike what happens at a turning point in a movie. When a secret is revealed we are forced back through the story to mentally review everything we've seen so far, sometimes changing the interpretation of entire scenes. [...] Since the player never completely leaves an area behind and forgets about it, the game world constantly expands in the mind of the player. By never completely exhausting an area b...

 The Idea of Objective Truth

Physical concepts are free creations of the human mind, and are not, however it may seem, uniquely determined by the external world. In our endeavour to understand reality we are somewhat like a man trying to understand the mechanism of a closed watch. He sees the face and the moving hands, even hears its ticking, but he has no way of opening the case. If he is ingenious he may form some picture of a mechanism which could be responsible for all the things he observes, but he may never be quit...

 Aristotle's Attempt to Categorize Motion

11 Now everything that changes place is moved either by itself or by something else. In as many of these as are moved by themselves, it is obvious that the moved and mover are together, since the first mover is present in them, so that nothing is in-between. But as many as are moved by other things must come about in four ways, for there are four kinds of change of place by means of something else: pulling, pushing, carrying, and whirling. For all motions with respect to place lead back to th...

 Movement According to Aristotle

241b 34 Every moving thing must be moved by something. For if it does not have the source of its motion in itself, it is clear that it is moved by something else (for another 40 thing will be the mover); but if it is in itself, let AB be taken, which is moving in its own right, and not by means of some part of it being moved. First, then, to suppose that AB is moved by itself since the whole is moved and by nothing outside it,would be as if, when KL was moving LM and was itself moving, one we...
