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.
Hermann Minkowski (1864–1909) found that the theory of special relativity could be best understood as a four-dimensional space, since known as the Minkowski spacetime.. In physics, Minkowski space (or Minkowski spacetime) (/ m ɪ ŋ ˈ k ɔː f s k i,-ˈ k ɒ f-/ [1]) is the main mathematical description of spacetime in the absence of gravitation.
Theoretical physicists believe math shows the possibilities of a fourth dimension, but there’s no actual evidence—yet.. Albert Einstein believed space and time made up a fourth dimension. An ...
A temporal dimension, or time dimension, is a dimension of time. Time is often referred to as the " fourth dimension " for this reason, but that is not to imply that it is a spatial dimension [ citation needed ] .

In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
Nonetheless, there is a way to visualize the Klein bottle as being contained in four dimensions. By adding a fourth dimension to the three-dimensional space, the self-intersection can be eliminated. Gently push a piece of the tube containing the intersection along the fourth dimension, out of the original three-dimensional space.
Then we have the four rotations R 1 = (+α, +α), R 2 = (−α, −α), R 3 = (+α, −α) and R 4 = (−α, +α). R 1 and R 2 are each other's inverses; so are R 3 and R 4. As long as α lies between 0 and π, these four rotations will be distinct. Isoclinic rotations with like signs are denoted as left-isoclinic; those with opposite signs as ...
