  2. Kaluza–Klein theory - Wikipedia

    en.wikipedia.org/wiki/Kaluza–Klein_theory

    Kaluza presented a purely classical extension of general relativity to 5D, with a metric tensor of 15 components. Ten components are identified with the 4D spacetime metric, four components with the electromagnetic vector potential, and one component with an unidentified scalar field sometimes called the "radion" or the "dilaton".

  3. Four-dimensionalism - Wikipedia

    en.wikipedia.org/wiki/Four-dimensionalism

    The B-series defines a given event as earlier or later than another event, but does not assume an objective present, as in four-dimensionalism. Much of the contemporary literature in the metaphysics of time has been taken to spring forth from this distinction, and thus takes McTaggart's work as its starting point.

  4. Five-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Five-dimensional_space

    The first approach is space-time-matter, which utilizes an unrestricted group of 5D coordinate transforms to derive new solutions of the Einstein's field equations that agree with the corresponding classical solutions in 4D spacetime. [8] Another 5D representation describes quantum physics from a thermal-space-time ensemble perspective and ...

  5. Four-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Four-dimensional_space

    Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

  6. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    When a series of autostereograms are shown one after another, in the same way moving pictures are shown, the brain perceives an animated autostereogram. If all autostereograms in the animation are produced using the same background pattern, it is often possible to see faint outlines of parts of the moving 3D object in the 2D autostereogram ...

  7. Nature connectedness - Wikipedia

    en.wikipedia.org/wiki/Nature_connectedness

    Nature connectedness (as a construct) is also known as nature relatedness, connectivity with nature, emotional affinity toward nature, or inclusion of nature in self. Although nature relatedness is a stable individual trait, it can change based on one's experience with nature, [ 8 ] meaning the more time an individual spends in nature, the more ...

  8. Principles of grouping - Wikipedia

    en.wikipedia.org/wiki/Principles_of_grouping

    The principles of grouping (or Gestalt laws of grouping) are a set of principles in psychology, first proposed by Gestalt psychologists to account for the observation that humans naturally perceive objects as organized patterns and objects, a principle known as Prägnanz. Gestalt psychologists argued that these principles exist because the mind ...

  9. Four-vector - Wikipedia

    en.wikipedia.org/wiki/Four-vector

    A four-vector A is a vector with a "timelike" component and three "spacelike" components, and can be written in various equivalent notations: [3] = (,,,) = + + + = + = where A α is the magnitude component and E α is the basis vector component; note that both are necessary to make a vector, and that when A α is seen alone, it refers strictly to the components of the vector.
