The team has developed a new algorithm that takes full control of the gonio-photometer to only capture a small subset of an inconceivably large four-dimensional space, enabling materials to be digitized much more rapidly than was previously possible.
Even though we live in the most highly developed society in the four-dimensional space, it is not easy to control the natural phenomenon due to the overuse, abuse or exploitation of natural resources.
A four-dimensional space or 4D space has been derived mathematically years ago.
We have already investigated that in the gravity model F(T) in the four-dimensional space we get the Friedmann equations according to (12) [11].
The pseudo-Riemannian (curved) four-dimensional space [V.sub.4] with the same set of the basis vectors is the basic space (space-time) of General Relativity.
Based on this, we can also analyse the dynamics of the material line length in the full four-dimensional space. Indeed, according to the Pythagorean theorem, the squared length of a small piece of material line is given by the sum of the squares of the corresponding lengths in the 2-dimensional subspaces: [L.sup.2] = [l.sup.2.sub.1] + [l.sup.1.sub.2], where both [l.sub.1] and [l.sub.2] follow log-normal distribution (Eq.
Sonner mapped the entangled quarks onto a four-dimensional space, considered a representation of space-time.
Finally putting theory to the test, Charbonneau and his team simulated glass formation in four-dimensional space and higher, eventually proving that a crucial assumption of that early glass-formation theory was wrong: The molecular structure within glass is much more disorderly than had been thought.
1943) has committed himself to drawing on his knowledge of math and physics to explore two- and three-dimensional representation of four-dimensional space. Thirty-eight of his extraordinarily patterned works are presented accompanied by essays by fellow artists (Joyce Kosloff, Robert Kushner), a mathematician, an art historian, and the artist himself.

Orthogonal rotation was used to orient each plane of the four-dimensional space so that one of the axes of the plane corresponded to the red-green opposition for color names, and the positive-negative opposition for names of emotions, and so that the point representing the word white and the emotion of calm would be as close as possible to the center of the plane.
