I believe that the principle that guided early scientists
was the belief that all things needed control. As examples:
Animals
must be tethered or retained by fenced fields
Soldiers
must be disciplined
Workers
must be (micro)managed
Machines
must be controlled
God
controls the Universe
Etc
I’m sure you get the point.
Thus Newton’s mechanics are full of control.
A body remains in a state of rest
or of uniform motion in a straight line unless acted upon by an external FORCE.
Bodies remain in orbit because of
the gravitational FORCE.
STANDARDIZED measures were proclaimed.
Thus laboratory experiments, naturally, were performed
within constraints. Gas would be in a container so its volume, pressure and temperature
were CONTROLLED.
One can, of course, argue the necessity of all this, because
experimental proof requires repeatability, and so on.
That’s all well and good. The question is: has this deprived
us of a whole lot of understanding about the behaviour of space/time/matter/forces
in uncontrolled situations? There are no fixed containers around newly forming
stars. Have we got a false idea of the constant arrow of time?
Relativity has given us (among other things) an inkling of
the need to think about different spacetime reference frames. In daily life we
think readily of changes in spacial dimensions versus time, but always regard
the passage of time as unvarying. What if it is spacetime that is fixed in its progression and the
rate of passage of time is variable? If time “stood still”, space would have to
expand, in order to compensate. (That might account for the inflation epoch in “Big
Bang” theory).
What if there are no rules?
Personally I think chaos theory is misnamed. For me, “chaos”
means “no rules”. Imagine if gravity was randomly variable versus time? Now
that would cause real chaos!
While I admit I tend to think of probabilistic approaches to
problems as being cop-outs for not understanding some underlying process, it
does appear that there’s a lot of probability “going on” in the universe. Could
it be that the laws of physics that we hold to be true are, themselves, random
in nature, and we just happen to be enjoying a spell of apparent consistency?
Hold on to your hats folks!
