The 10th Session of Course 1

Two things interact in a situation. These objects or phenomena change relative to each other as both things associated in space and as two items that act as placeholders in both their individual relative time and their collective relative time. Suppose that each of these two items were a cane. Two canes. Both of these canes struck each other in many ways at the top of their structures, yet the canes never pulled each other to any significant sway, and thus only interacted as a static force that redistributed the ends of each other. Now let's say that the bottom of the canes were held by a highly powerful grip that had a leeway of some elastic modulae. In other words, the bottoms of the canes were held tightly, yet by a medium that was not rigid -- like a pair of hands. When the canes at their tops were to strike, these would be momentarily redistributed, while then returning to an approximation of their original spot. Like you can see, their differentiation would be static, and no significant net change would appear over any transient period of time in terms of the appearance of the scene. Yet, if you were to hook the ends of the canes, there would be a chance that one of the canes would pull the other. Even if both of the people holding the canes were of equal strength, depending on how the canes were twisted and/or torqued, could cause a net change in how these would be pulled.
Tug has to do with push-pull action. In order for there to be a push or a pull, there must be some static connection for at least one moment. For instance, you push a stone. In order for you to move it at all, your hand must have some interaction with the stone for at least one moment. If you tried to lift anything without interconnection, your hands would slip and you wouldn't be able to lift it. When something pulls something else, there is a significant static modulae that allows for the puller to pull. This interconnection is classically done when the two objects are hooked one onto another.
Waves tug, since these push and/or pull. The interconnection comes through electrostatics and/or hookable cusps in the morphology of the waves' structure. Strong electromagnetic fields pull in more wavelike phenomena, while strong electrostatic fields such as a high voltage fence will actually push out a person who tries messing with it. (High amps will pull you in and electrocute you, while a high voltage/low amperage situation will knock you away once the low amperage momentarily attempts to pull you in.) This is because amperage is charge per second, and a high amount of electrical charge flowing in a limited amount of time hooks any adjacent conductive material since this will balance the adjacent electrical band levels, and voltage is energy per charge, and if a wire has a lot of energy per charge, yet not much charge is flowing through the wire per time, then the low charge per time will barely attempt to pull the person while the wire's high energy will form a field that will repel the person as they are being shocked. Both examples of pull and push are examples of how interaction is a matter of wave-tug. General relocalization of particles is due to the various tendencies of wave-tug.
