Snowflake geometry
September 19, 2008
Ice crystals formed in the appropriate conditions can often be thin and flat. These planar crystals may be simple hexagons, or if the supersaturation is high enough, develop branches and dendritic (fern-like) features and have six approximately identical arms, as per the iconic ‘snowflake‘ popularised by Wilson Bentley. The 6-fold symmetry arises from the hexagonal crystal structure of ordinary ice, the branch formation is produced by unstable growth, with deposition occurring preferentially near the tips of branches.
The shape of the snowflake is determined broadly by the temperature and humidity at which it forms. Rarely, at a temperature of around −2 °C (28 °F), snowflakes can form in threefold symmetry — triangular snowflakes. The most common snow particles are visibly irregular, although near-perfect snowflakes may be more common in pictures because they are more visually appealing.
Police jewelry
September 16, 2008
Police are agents or agencies, usually of the executive, empowered to enforce the law and to effect public and social order through the legitimatized use of force. The term is most commonly associated with police departments of a state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. The word comes via French from the Latin politia (“civil administration”), which itself derives from the Ancient Greek πόλις, for polis (“city”).
The first police force comparable to present-day police was established in 1667 under King Louis XIV in France, although modern police usually trace their origins to the 1800 establishment of the Marine Police in London, the Glasgow Police, and the Napoleonic police of Paris. The first modern police force is also commonly said to be the London Metropolitan Police, established in 1829, which promoted the preventive role of police as a deterrent to urban crime and disorder.

Dolphin Diamond Jewelry

Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera.
Dolphins have long played a role in human culture. Dolphins are common in Greek mythology and there are many coins from the time which feature a man or boy riding on the back of a dolphin. The Ancient Greeks treated them with welcome; a ship spotting dolphins riding in their wake was considered a good omen for a smooth voyage. In Hindu mythology, the Ganges River Dolphin is associated with Ganga, the deity of the Ganges river.
