The sandpile model is a cellular automaton originally defined on a rectangular grid (checkerboard) of the standard square lattice.To each vertex (site, field) (,) of the grid, we associate a value (grains of sand, slope, particles) (,) {,,,}, with {,,,} referred to as the (initial) configuration of the sandpile.
Self-organized criticality (SOC) is a property of dynamical systems that have a critical point as an attractor.Their macroscopic behavior thus displays the spatial or temporal scale-invariance characteristic of the critical point of a phase transition, but without the need to tune control parameters to a precise value, because the system, effectively, tunes itself as it evolves towards ...
Structured criticality is a property of complex systems in which small events may trigger larger events due to subtle interdependencies between elements. This often gives rise to a form of stratified chaos where the general behavior of the system can be modeled on one scale while smaller- and larger-scale behaviors remain unpredictable.
Critical thinking is the process of analyzing available facts, evidence, observations, and arguments to make sound conclusions or informed choices. It involves recognizing underlying assumptions, providing justifications for ideas and actions, evaluating these justifications through comparisons with varying perspectives, and assessing their rationality and potential consequences.

The notion of critical understanding is closely related to the concept of Critical Thinking, described as, ‘reasonable reflective thinking focused on deciding what to believe or do.’ [7] Critical thinking has also been described as, ‘thinking about thinking’, [8] specifically in relation to John Dewey’s work on ‘the problem of training thought’.

A critical friend is a supportive person who can ask difficult questions using critical thinking to judge a situation. [1] The term has its origins in critical pedagogy education reforms in the 1970s and arose out of the self-appraisal activity which is attributed to Desmond Nuttall. [2] One of the most widely used definitions is from 1993,
