Macro photography of a natural snowflake. A snowflake is a single ice crystal that is large enough to fall through the Earth's atmosphere as snow. [1] [2] [3] Snow appears white in color despite being made of clear ice.
The Koch snowflake (also known as the Koch curve, Koch star, or Koch island [1] [2]) is a fractal curve and one of the earliest fractals to have been described. It is based on the Koch curve, which appeared in a 1904 paper titled "On a Continuous Curve Without Tangents, Constructible from Elementary Geometry" [3] by the Swedish mathematician Helge von Koch.
Longwave radiation is received by the snowpack from many sources, including ozone, carbon dioxide, and water vapor present in all levels of the atmosphere. Longwave radiation is also emitted by the snowpack in the form near–black-body radiation, where snow has an emissivity between 0.97 and 1.0. [3]
Various collaborative online encyclopedias were attempted before the start of Wikipedia, but with limited success. [19] Wikipedia began as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. [20]

Twitter uses snowflake IDs for tweets, direct messages, users, lists, and all other objects available over the API. [7] Discord also uses snowflakes, with their epoch set to the zeroth second of the year 2015. [3] Instagram uses a modified version of the format, with 41 bits for a timestamp, 13 bits for a shard ID, and 10 bits for a sequence ...
Alternative light sources use phosphors or combinations of mono-chromatic LEDs (red, blue, and green) to produce "white" light, giving significantly irregular spectral distributions that can create color casts in photography and differences of color matching when compared to incandescent light or daylight.
