 Geometry and cellular automata
It is conceivable that hyperbolic geometry describes the world when considered on a cosmological scale; however, for this to be the case, the proportionality constant between the angle deficit for a triangle and its area would have to be exceedingly small (Figure 1).
The tessellation (lattice structure) produced by a number of tiles (cells) is dependent on the geometry of the individual tiles: standard two-dimensional CA adopt a homogeneous tile (cell) geometry which is usually regular square, although hexagonal tile structures have been investigated in the literature.
The hexagonal lattice has been shown to have a geometry which is suitable for modelling the behaviour of a large class of natural systems including the diffusion of gases and crystal growth processes in which packing density is assumed to be uniform and optimal (hexagonal close packing).

If one could find the area contained by the square on C in terms of the values A and B, the length of the diagonal C could be determined by taking the square root of this area amount.
As a result, it can be empirically seen that if one adds the area of the square on A to the area of the square on B and then subtracts the area of two AB rectangles, what remains is the equivalent of the area of the square on (B-A).

 nature's word | musings on sacred geometry
Sacred Geometry was passed from the Romans to European Medieval civilization via the stonemason tradition.
When we superimpose a matrix based on the square root of two upon these marks (the marks consist of the darker lines in the images), it becomes obvious that these symbols were much more than asthetic designs.
Apparently, the Masons were quite dedicated to employing Sacred Geometry in all of their works, even down to the signature marks they used to sign their their works.

 Geometry -- Square Root of 2 Background
If you take a shortcut across square field, you go 1.4 sides instead of 2.0; if your head is 21 inches around, you can tie your 18-inch bandana around your forehead, because 18 times 1.4 is 25.2 inches.
Unit squares and their diagonals, and the half-square (45-45-90 triangles), appear all the time in geometry and in real life.
If 1/2 and 3/4 are benchmark fractions that every fourth grader should know, the square root of 2—the length of that diagonal, that is, the hypotenuse of the isosceles right triangle—is a benchmark irrational number (along with pi and a few others).

Geometry images can be compressed using lossy as well as lossless forms of traditional 2D image compression.
The natural extension of geometry images for mesh compression are geometry videos for animation compression.
Geometry images improve this process since they can not only generate the normal map - they can also automatically supply the low-poly model as well as the texture coordinates for it.

 Acute Square Triangulation
An old puzzle asks for a partition of the square into triangles in which all angles are strictly acute.
The dashed lines mark the boundaries of the quadtree squares, and indicate that certain half-tiles can be recombined to form three more tiles, including one in which a square is divided into 26 triangles, all having angles of at most 80 degrees.
Use as triangulation vertices these four points on the square's sides, the two centers of the pentagons (on one diagonal of the square), and the two points on the other diagonal where the pentagons share a corner.

In mathematics, the principal square root of a non-negative real number is denoted and represents the non-negative real number whose square (the result of multiplying the number by itself) is x\,\!.
Square roots of positive integers are often irrational numbers, i.e., numbers not expressible as a quotient of two integers.
The discovery that \sqrt 2 is irrational is attributed to Hippasus, a disciple of Pythagoras.

 Nike Golf's geometry: radical new Square Sumo Driver. Callaway FT-i
We're talking geometry, golf geometry, and the thought of geometry or trigonometry of any kind still brings on bad memories of tangents and co-tangents and anxiety attacks, going back to seventh-period math class in high school.
Discussions about geometry, and drivers with square, triangular, bullet-like and other newfangled shapes dominated the aisles of the 54th annual PGA Merchandise Show, which moved into the Orange County Convention Center in Orlando, Fla., on Jan. 25 for a three-day stay.
TaylorMade, for one, has been particularly vocal in not building a square driver, stating that the negatives of a square driver outweigh the positives that can be achieved in boosting MOI in other ways.

 The letter G
Though supposed to represent Geometry and occupying the place of honour in the Lodge, the outline of this letter stands pronounced as the most ungeometrical and therefore the most unmasonic of our emblems.
The reason of this discrepancy is not far to seek when we call to mind the fact that the present form of the letter dates no further back than the middle of the third century B.C., and its intrusion among Masonic emblems can be regarded in no other light than as a comparatively modern innovation.
The square is one of the working tools of a fellow-craft and is the emblem of that just relation between man and man which entitled the workman relying on the honesty of his work and on the integrity of his employer, to claim without scruple and without diffidence the due reward of his labour.

The geometry of Babylon (in Mesopotamia) and Egypt was mostly experimentally derived rules used by the engineers of those civilizations.
His major work in geometry is "Synagoge" or the "Collection" (in 8 Books), a handbook on a wide variety of topics: arithmetic, mean proportionals, geometrical paradoxes, regular polyhedra, the spiral and quadratrix, trisection, honeycombs, semiregular solids, minimal surfaces, astronomy, and mechanics.
is considered the father of both descriptive geometry in "Geometrie descriptive" (1799); and differential geometry in "Application de l'Analyse a la Geometrie" (1800) where he introduced the concept of lines of curvature on a surface in 3-space.

 The Diamond Theorem
Let G be the group of 322,560 permutations of these 16 tiles generated by arbitrarily mixing random permutations of rows and of columns with random permutations of the four 2x2 quadrants.
This can be seen by viewing the 35 structures as three-sets of line diagrams, based on the three partitions of the four-set of square two-color tiles into two two-sets, and indicating the locations of these two-sets of tiles within the 4x4 patterns.
The underlying geometry of the 4x4 patterns is closely related to the Miracle Octad Generator of R. Curtis-- used in the construction of the Steiner system S(5,8,24)-- and hence is also related to the Leech lattice, which, as Walter Feit has remarked, "is a blown up version of S(5,8,24)."
