It seems to me that the fundemental principal that runs our lives is the Sine wave.  It's the shape of light (if you could take a really close look at it) and it looks like this   or   or  .
It determines how we and the things around us work.  It's speed, frequency, and velocity (?) determine temperature, growth, movement at every level from planets to microbes to how tight a turn a car can make on a curve.  It defines these things.  It sets the limit of what hpappens next.  The temperature can only change so fast.  Plant growth due to lack of water can't stop, only slow down at a certain rate depending on the circumstances leading to that point.  Every movement is dictated/a consequenceof by the movemnt that brought it to that place:  the speed, velocity, frequency (amount of energy), and the changes that the newly applied forces can be applied to the sine wave (if you are running and try turning 90 degrees, the forces you apply to change your course can ony create a tightness of turn depending on how fast you were running, angle of the ground, etc).

I believe these same forces apply to our mental processes as well.  If we are ina very up and down period (steep sine wave), we can't suddenly be calm.  If calm (shallow sine wave) we don't instantly become excited.  Even more so, the general patterns of our lives lead us
