Brownian motion <strong>and</strong> drift<br />

The point, which represents a situation in the space of existence, never remains in the same place<br />

<strong>for</strong> any real, especially alive, system. It is moving due to external <strong>and</strong> internal reasons, or even<br />

without reasons, just because of accidental fluctuations. In any case, the situation is changing.<br />

Nobody can stop it.<br />

The basic <strong>for</strong>m of change may be illustrated as the stochastic motion of a dot that describes the<br />

current state of a system. This stochastic motion fills in a certain zone within the space of<br />

existence – the size of the zone depends on the temperature <strong>and</strong> the structure – the higher the<br />

temperature, <strong>and</strong> the less strong the structural interrelations, the more dynamic the moves may be<br />

over a bigger zone. This kind of motion was called Brownian motion - named <strong>for</strong> Robert Brown,<br />

who discovered it in 1827 - <strong>and</strong> usually applies to any of various physical phenomena in which<br />

some quantity of elements are constantly undergoing small r<strong>and</strong>om fluctuations. In stable<br />

situations, a centre of Brownian motion remains in the same place. Certain micro-chaos is trapped<br />

by the structure that does not allow the system to move too far away. Mechanisms of homeostatic<br />

regulation maintain it in close surrounding to a certain point of balance.<br />

Picture 14. Brownian motion<br />

At any given moment our system may move in any accidental direction (the question - why in this<br />

or that direction? – makes no sense). It just happens. There is no reason. The next move will be in<br />

another direction; t is impossible to predict which one. It is unpredictable. What is predictable that<br />

is the size of the zone occupied, <strong>and</strong> the location of the centre of balance.<br />
