Shilpa Shastras (Sanskrit: शिल्प शास्त्र śilpa śāstra) literally means the Science of Shilpa (arts and crafts). [1] [2] It is an ancient umbrella term for numerous Hindu texts that describe arts, crafts, and their design rules, principles and standards.
Originating in ancient India, Vastu Shastra (Sanskrit: वास्तु शास्त्र, vāstu śāstra – literally "science of architecture" [2]) is a traditional Hindu system of architecture [3] [4] based on ancient texts that describe principles of design, layout, measurements, ground preparation, space arrangement, and spatial geometry.

32-point compass rose. The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography.A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and ...
The numbers of vertices in any two color classes differ by at most one. That is, the partition of vertices among the different colors is as uniform as possible. For instance, giving each vertex a distinct color would be equitable, but would typically use many more colors than are necessary in an optimal equitable coloring.
With four colors, it can be colored in 24 + 4 × 12 = 72 ways: using all four colors, there are 4! = 24 valid colorings (every assignment of four colors to any 4-vertex graph is a proper coloring); and for every choice of three of the four colors, there are 12 valid 3-colorings. So, for the graph in the example, a table of the number of valid ...
In graph-theoretic terms, the theorem states that for loopless planar graph, its chromatic number is ().. The intuitive statement of the four color theorem – "given any separation of a plane into contiguous regions, the regions can be colored using at most four colors so that no two adjacent regions have the same color" – needs to be interpreted appropriately to be correct.
The colours associated with the four creatures can be said to match the colours of soil in the corresponding areas of China: the bluish-grey water-logged soils of the east, the reddish iron-rich soils of the south, the whitish saline soils of the western deserts, the black organic-rich soils of the north, and the yellow soils from the central ...
A map is a function, as in the association of any of the four colored shapes in X to its color in Y. In mathematics, a map or mapping is a function in its general sense. [1] These terms may have originated as from the process of making a geographical map: mapping the Earth surface to a sheet of paper. [2]
