  2. Integrated information theory - Wikipedia

    en.wikipedia.org/wiki/Integrated_information_theory

    Phi; the symbol used for integrated information. Integrated information theory (IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...

    en.wikipedia.org/wiki/Phi

    The diameter symbol in engineering, ⌀, is often erroneously referred to as "phi", and the diameter symbol is sometimes erroneously typeset as Φ. This symbol is used to indicate the diameter of a circular section; for example, "⌀14" means the diameter of the circle is 14 units. A clock signal in electronics is often called Phi or uses the ...

    Integrated information theory (IIT) the symbol of which is φ is a mathematical theory of consciousness developed under the lead of the neuroscientist Giulio Tononi Standard normal distribution , Φ ( x ) {\displaystyle \Phi (x)} notating its cumulative distribution function and ϕ ( x ) {\displaystyle \phi (x)} its probability density function

    Particular care must be taken to check the meaning of the symbols. The mathematics convention. Spherical coordinates (r, θ, φ) as typically used: radial distance r, azimuthal angle θ, and polar angle φ. + The meanings of θ and φ have been swapped—compared to the physics convention. The 'south'-direction x-axis is depicted but the 'north ...

    The eight-circuit model of consciousness is a holistic model originally presented as psychological philosophy (abbreviated "psy-phi" [1]) by Timothy Leary in books including Neurologic (1973) and Exo-Psychology (1977), later expanded on by Robert Anton Wilson in his books Cosmic Trigger (1977) [2] and Prometheus Rising (1983), and by Antero Alli in his books Angel Tech (1985) and The Eight ...

    en.wikipedia.org/wiki/Greek_letters_used_in...

    Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

  8. Phi phenomenon - Wikipedia

    en.wikipedia.org/wiki/Phi_phenomenon

    Reverse phi illusion is the kind of phi phenomenon that fades or dissolves from its positive direction to the displaced negative, so that the apparent motion human perceive is opposite to the actual physical displacement. Reverse phi illusion is often followed by black and white patterns.

    Maps of Meaning: The Architecture of Belief is a 1999 book by Canadian clinical psychologist and psychology professor Jordan Peterson. The book describes a theory for how people construct meaning , in a way that is compatible with the modern scientific understanding of how the brain functions. [ 1 ]
