Th e u n divided u n iverse

V,, coming from both slits . Near the zeros of the wave fu n ction the osmotic veloci ty approaches infin ity an d is directed away from the zeros . Thus a particle diffusing randomly an d app roaching a zero is certain to be turned arou nd before i t c an reach this zero. Th is exp l ains why no particle e ver reaches the points where the wave function is zero . And , as we have in deed already pointed ou t , the osmotic velocity is constantly pushing the part icle to the regions of highest / ¢ / 2 an d this explains why most particles are found near the maxima of the wave function .

Without assu ming an osmotic velocity field of this kind , there wou l d be no way of expl aining such phenomen a. As a result of random motions , for example , a partide j u st undergoing a random process on its own wou ld h ave no way of ‘ knowi ng’ that it should avoid the zeros of the wave fu nc tion .

To obtain a consistent overal l picture we must consider the ran dom backgrou nd field . Th is is assumed , as we have already pointed ou t , to b e t h e sou rce o f the ran dom motions of t h e particle, but in ad dition it must determine a condition in space which gives rise to the osmotic veloci ty.

In deed , a single particle in random motion can not contain any information capable of determining, for example , that every time it approaches the zero of a wave function it must turn around . This information cou ld be contained only in the backgrou nd fiel d itself. Therefore , the stoch astic model does not fulfil the expectations that wou ld at first be raised by its name , that is to provide an explanation solely in terms of the random movements of a particle without reference to a quantum mech anical field (wh ich may be taken as p and S or as ¢ = ,/peiS/li ).

I n the interpret ation that we have been gi ving throughou t this book , this field h as the property that i ts effect does not depend on its amplitude.

As we have suggested in earlier chap ters , this behaviour c an be understood in terms of the concept of acti ve information , i .e . that the movement comes from the particle itself, which is however ‘ informed ‘ or ‘guide d ‘ by the field .

In the stoch astic interpret ation there is a further effect of the quantu m field through the osmotic velocity, wh ich is also independent of i ts ampli tude .

We can therefore say that along with the mean velocity field , VS/ m ,
