Dark Winter

Dark Winter may refer to:

Darkness

Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.

Humans are unable to distinguish color when either light or darkness predominate. In conditions of insufficient light, perception is achromatic and ultimately, black.

The emotional response to darkness has generated metaphorical usages of the term in many cultures.

Scientific

Perception

The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.

Physics

In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. For example, a matte black paint does not reflect much visible light and appears dark, whereas white paint reflects much light and appears bright. For more information see color.

Light cannot be absorbed without limit. According to the principle of the conservation of Energy, energy cannot be created or destroyed; it can only be converted from one type to another. Consequently, most objects that absorb visible light reemit it as heat. So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive. For more information see thermodynamics.

Winter

Winter is the coldest season of the year in polar and temperate climates, between autumn and spring. Winter is caused by the axis of the Earth in that hemisphere being oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter is associated with snow and freezing temperatures. The moment of winter solstice is when the sun's elevation with respect to the North or South Pole is at its most negative value (that is, the sun is at its farthest below the horizon as measured from the pole), meaning this day will have the shortest day and the longest night. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winter solstice, however, and these depend on latitude, due to the variation in the solar day throughout the year caused by the Earth's elliptical orbit (see earliest and latest sunrise and sunset).

Amazon Music

Amazon Music (previously Amazon MP3) is an online music store and music locker operated by Amazon.com. Launched in public beta on September 25, 2007, in January 2008 it became the first music store to sell music without digital rights management (DRM) from the four major music labels (EMI, Universal, Warner Music, and Sony BMG), as well as many independents. All tracks were originally sold in 256 kilobits-per-second variable bitrate MP3 format without per-customer watermarking or DRM; however, some tracks are now watermarked. Licensing agreements with recording companies restrict the countries in which music can be sold: Amazon.com only sells music to US customers while Amazon.co.uk only sells music to UK customers.

After the United States, Amazon MP3 was launched in the United Kingdom on December 3, 2008, in Germany on April 1, 2009, and in France on June 10, 2009. The German edition has been available in Austria and Switzerland since December 3, 2009. The Amazon MP3 store was launched in Japan on November 10, 2010. The Spanish and Italian editions were launched on October 4, 2012.
