An Illustration of Shape Evolution

 

The next figure shows an illustration of shape evolution. Each successive stage is given by an operation of the grammar. The sequence of operations is CM- followed by BM+ followed by Cm+ :

Let us describe what his happening in the above figure:

(1) The entire history is dependent on a single crucial process. It is the internal resistance represented by the bold upward arrow in the first shape (above).

(2) This process continues upward until it bursts out and creates the protrusion shown in the second shape (above).

(3) This process then bifurcates, creating the upper lobe shown in the third shape above. Involved in this stage is the introduction of a squashing process given by the bold downward arrow at the top of the third shape.

(4) Finally, the downward squashing process continues till it causes the new indentation in the top of the fourth shape above.

 


 

The six rules of the Process Grammar are only a small part of the vast study of process-inference carried out in my MIT Press book: Symmetry, Causality, Mind. The Process Grammar is presented in the beginning of the book, and then there are another 600 pages on the inference of processes from shape. To see more information about this book, click:
