  2. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    Depending on which features of general relativity and quantum theory are accepted unchanged, and on what level changes are introduced, [204] there are numerous other attempts to arrive at a viable theory of quantum gravity, some examples being the lattice theory of gravity based on the Feynman Path Integral approach and Regge calculus, [191 ...

    From Bacteria to Bach and Back: The Evolution of Minds is a 2017 book about the origin of human consciousness by the philosopher Daniel Dennett, in which the author makes a case for a materialist theory of mind, [1] arguing that consciousness is no more mysterious than gravity.

  4. Theory of relativity - Wikipedia

    en.wikipedia.org/wiki/Theory_of_relativity

    The term "theory of relativity" was based on the expression "relative theory" (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression "theory of relativity" (German: Relativitätstheorie ...

    en.wikipedia.org/wiki/Tree_of_knowledge_system

    Mind/cognition in the ToK system refers to the set of mental behaviors. Mental behaviors are behaviors of animals mediated by the nervous system that produce a functional effect on the animal-environment relationship. As such, Mind/cognition is essentially synonymous with what behavioral psychologists have meant when they use the term behavior.

    While there are promising candidates for such a theory of quantum gravity, notably string theory and loop quantum gravity, there is at present no consistent and complete theory. It has long been hoped that a theory of quantum gravity would also eliminate another problematic feature of general relativity: the presence of spacetime singularities ...

    en.wikipedia.org/wiki/Electromagnetic_theories...

    In McFadden's cemi field theory, as well as in Drs Fingelkurts' Brain-Mind Operational Architectonics theory, the brain's global EM field modifies the electric charges across neural membranes, and thereby influences the probability that particular neurons will fire, providing a feed-back loop that drives free will. However, in the theories of ...

  9. History of gravitational theory - Wikipedia

    en.wikipedia.org/.../History_of_gravitational_theory

    The 12th-century scholar Al-Khazini suggested that the gravity an object contains varies depending on its distance from the centre of the universe (referring to the centre of the Earth). Al-Biruni and Al-Khazini studied the theory of the centre of gravity, and generalized and applied it to three-dimensional bodies.
