The shape of the snowflake is determined broadly by the temperature and humidity at which it is formed. [8] Rarely, at a temperature of around −2 °C (28 °F), snowflakes can form in threefold symmetry — triangular snowflakes. [9] Most snow particles are irregular in form, despite their common depiction as symmetrical.
Scale invariance is an exact form of self-similarity where at any magnification there is a smaller piece of the object that is similar to the whole. For instance, a side of the Koch snowflake is both symmetrical and scale-invariant; it can be continually magnified 3x without changing shape. The non-trivial similarity evident in fractals is ...
Snowflake sixfold symmetry. Symmetry is widespread in living things. Animals that move usually have bilateral or mirror symmetry as this favours movement. [2]: 48–49 Plants often have radial or rotational symmetry, as do many flowers, as well as animals which are largely static as adults, such as sea anemones.
Fivefold symmetry is found in the echinoderms, the group that includes starfish, sea urchins, and sea lilies. [31] Among non-living things, snowflakes have striking sixfold symmetry; each flake's structure forms a record of the varying conditions during its crystallization, with nearly the same pattern of growth on each of its six arms.

An early classification of snowflakes by Israel Perkins Warren. [2] Snow was described in China, as early as 135 BCE in Han Ying's book Disconnection, which contrasted the pentagonal symmetry of flowers with the hexagonal symmetry of snow. [3] Albertus Magnus proved what may be the earliest detailed European description of snow in 1250.
Now he’s gonna need a good lawyer.. A Florida defense lawyer was busted for allegedly smuggling legal documents soaked in the wild synthetic marijuana known as K2 into jail so inmates could get ...
A snowflake consists of roughly 10 19 water molecules which are added to its core at different rates and in different patterns depending on the changing temperature and humidity within the atmosphere that the snowflake falls through on its way to the ground. As a result, snowflakes differ from each other though they follow similar patterns. [17 ...
