Memetic Horizon

When I was riding a bus and it was struck by a delivery truck I began thinking about physics and the effect of two objects colliding. We can calculate, if we know the velocity, mass and any environmental factors, the new trajectories. In a real world practical adaption of this, however, it fails to accommodate the consequences when said objects have a meaning beyond their physical composition. Were we talking about asteroids in space then there wouldn't be much to talk about. If we were talking about amoeba, again, not much to talk about. Once the objects are of species possessing multiple neurons we may record something else. The laws of physics do not change, but aren't the end of our tale. Let us say object (a) is an ant and object (b) is a brown recluse spider. Velocities change, then change again as the spider precedes to pounce on the ant.
The "higher" the lifeform the more complex the reaction potential. Mammals have complex social structures, and besides hunting and mating, also have family obligations. When speaking of humans, millions of individuals lives can be changed, nations moved, by a simple physics equation e.g. assassination of the Austrian Archduke in 1914.
It is fascinating to think of the simple physical reactions that can produce such varied reactions in our minds. Tossing a ball and tossing a baby, jumping off a step and jumping off a bridge. The latent chemical reactions within our brains being triggered by a low energy external event. After the commuter bus was grazed by the delivery truck we had to sit and wait for another bus to pick us up. While waiting, motorists slowed and watched, a law enforcement agent came by to assist and I was late for my second bus.
