The evolution of man, ever since the first hominids appeared, has been driven and characterized by numerous factors of diverse nature, such as geography, climate, ethnicity, superstitions and, with time, religion, art, science and philosophy, just to name a few. However, the common thread that may be observed throughout history is the formation of structures…
We report verbatim a 1998 article A Survey of “Complexity Measures” by David P. Feldman and Jim Crutchfield. A more adequate title for this evasive article would be “A Survey of How Science Avoids to Measure Complexity”. Once you’ve read it, ask yourself this: can I use any of these measures to actually measure the…
From the Wikipedia: A cellular automaton is a discrete model studied in computability theory, mathematics, physics, complexity science, theoretical biology and microstructure modelling. It consists of a regular grid of cells, each in one of a finite number of states, such as “On” and “Off” (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called…
Of all physical quantities, energy is probably the most important. Energy expresses the capacity of a body or a system to perform work. Nature works by using energy to transform matter. This is done via processes (physical, chemical, etc.). However, in order to realize these processes it is necessary to have information. Energy on its…
