Many peoples belief's of what is random is fundamentally misplaced. Nothing is truly random, it only has the appearance of being so. Let me try to explain...
It is fair to say that if you knew the position of two molucules in a vacuum sealed jar and the relative direction and velocity of these particles, then in theory, we can predict the position of those two molocules at any time in the future by calculating how they will bounce off the walls of the jar and also each other, etc? That sounds fairly feasible, doesn't it? But in practice we discover we cannot actually do this because the jar is part of a larger system that is influenced by the heat of objects around it, the gavitational pull of those objects and a fininte number of other factors, all which influence the movement of the molocules in the jar.
So the model we originally had needs tweaking to take into account all these factors, unfortunately, at this moment in our history we don't have the computing power to accomplish that. However, just because we can't predict where two mocules will be positioned doesn't mean we can't approximate the behaviour of even more particles! For instance we can determine with some accuracy how a jar full of air particles will react to heat being applied to it using mathematical formula that computers today can execute with ease. And although we won't know the location of each particle, we will know (very accurately too) about the pressure build up (due to the gas trying to expand due to the increased movement of the particles within the jar) and various other factors that will occur because of the heat being applied to the jar.
On occasions a blurred, peripherary vision supplies enough detail for what we want to see. The mind has an amazing way of filtering the visual noise to see what lies hidden beneath.
