Conways Game of Life
Can a limited set of laws govern a three-dimensional system? A deterministic system where after setting an initial condition the laws determine what happens next. Just like in a Conway world model.
Starting from a given initial condition, these laws generate one generation after another. The fundamental physics of such a model may be simple, but the resulting chemistry can lead to complexity.
An organ (and by extension a living being) can be defined as a complex system of limited size.
It is estimated, based on the earlier work of mathematician John von Neumann, that the minimum size of a self-propagating pattern such as in Conway models is about 10 trillion cells. This roughly corresponds to the number of molecules in a human cell.
Each of the 37 trillion cells in the human body contains around 10^{14} Â molecules. These molecules are responsible for the myriad of biochemical processes that sustain life. The diversity and complexity of these molecules contribute to the unique molecular characteristics of each cell.
And could the outcome be disease? Possible.
