Mathematically, a four-dimensional space is a space with four spatial dimensions, that is a space that needs four parameters to specify a point in it. For example, a general point might have position vector a, equal to $${\displaystyle \mathbf {a} ={\begin{pmatrix}a_{1}\\a_{2}\\a_{3}\\a_{… 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 … See more In the familiar three-dimensional space of daily life, there are three coordinate axes—usually labeled x, y, and z—with each axis orthogonal (i.e. perpendicular) to the other two. The six cardinal directions in this space can be called up, down, east, west, north, and … See more Research using virtual reality finds that humans, despite living in a three-dimensional world, can, without special practice, make … See more In art In literature Science fiction texts often mention the concept of … See more Lagrange wrote in his Mécanique analytique (published 1788, based on work done around 1755) that mechanics can be viewed as operating in a four-dimensional space— three dimensions of space, and one of time. As early as 1827, Möbius realized … See more The geometry of four-dimensional space is much more complex than that of three-dimensional space, due to the extra degree of freedom. See more To understand the nature of four-dimensional space, a device called dimensional analogy is commonly employed. Dimensional analogy is the study of how (n − … See more Webfourth dimension. 1. the dimension of time, which is necessary in addition to three spatial dimensions to specify fully the position and behaviour of a point or particle. 2. the concept in science fiction of a dimension in addition to three spatial dimensions, used to explain supranatural phenomena, events, etc.

Just as the three dimension vector locating a position in space, ( x, y, z) is generalised to a 4 dimensional vector ( x, y, z, c t) that includes time, we can generalise most of our 3 dimension vectors to 4 vectors. The three dimensions of momentum become ( p x, p y, p z, E / c). tarawa tatouage
