Dawn

Dawn (from an Old English verb dagian "to become day") is the time that marks, depending on the specific usage, the beginning of the twilight before sunrise, the period of the pre-sunrise twilight or the time of sunrise. When identified as the beginning of or the period of twilight, it is recognized by the presence of weak sunlight, while the Sun itself is still below the horizon.

Types of dawn

Different definitions exist for the start of dawn. The difference between these definitions is the amount of sunlight that must be present. This can be correlated with the angular distance of the centre of the Sun (degrees) below the horizon, in the morning:

Dawn of astronomical twilight

Astronomical twilight begins at the moment after which the sky is no longer completely dark. This occurs when the Sun is 18 degrees below the horizon in the morning. Though it is possible to localize the direction of the Sun during astronomical dawn and dusk, people in general experience astronomical dawn and dusk as night, even without clouds. The zenith is dark and more than just the brightest stars can be seen (except low above the horizon in the direction of the sun).

Rain

Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.

The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, desert climates can exist due to the dry air caused by downslope flow which causes heating and drying of the air mass. The movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes.

Bruno Mars

Peter Gene Hernandez (born October 8, 1985), professionally known by his stage name Bruno Mars, is an American singer, songwriter, record producer, and choreographer. Born and raised in Honolulu, Hawaii, by a family of musicians, Mars began making music at a young age and performed in various musical venues in his hometown throughout his childhood. He graduated from high school and moved to Los Angeles to pursue a musical career. Mars produced songs for other artists, co-founding the production team The Smeezingtons.

Mars had an unsuccessful stint with Motown Records, but then signed with Atlantic in 2009. He became recognized as a solo artist after lending his vocals to the songs "Nothin' on You" by B.o.B, and "Billionaire" by Travie McCoy, which were international successes, and for which he co-wrote the hooks. His debut studio album, Doo-Wops & Hooligans (2010), was anchored by the U.S. Billboard Hot 100 chart-topping singles "Just the Way You Are" and "Grenade", as well as the number-five single "The Lazy Song". His second album, Unorthodox Jukebox, released in 2012, peaked at number one in the United States. The album spawned the international singles "Locked Out of Heaven", "When I Was Your Man" and "Treasure".

Demetri Martin

Demetri Evan Martin (born May 25, 1973) is an American comedian, actor, artist, musician, writer, and humorist. He is best known for his work as a stand-up comedian, being a contributor on The Daily Show, and his Comedy Central show Important Things with Demetri Martin.

Early life

Martin was born on May 25, 1973 to a Greek American family in New York City, New York, the son of nutritionist Lillian and Greek Orthodox priest Dean C. Martin (now deceased). He grew up in Toms River, New Jersey, and has a younger brother named Spyro.

Martin graduated from Yale University in 1995. During his time there, he wrote a 224-word poem about alcoholism as a project for a fractal geometry class, which became a well known palindromic poem. He was also a member of the Anti-Gravity Society, whose members juggle objects on Sunday evenings on Yale's Old Campus.

Although Martin was accepted into Harvard Law School, he went to New York University School of Law after he received a full scholarship. Martin withdrew from law school before the start of his final year, opting to pursue comedy over finishing his Juris Doctor.

Still life

A still life (plural still lifes) is a work of art depicting mostly inanimate subject matter, typically commonplace objects which may be either natural (food, flowers, dead animals, plants, rocks, or shells) or man-made (drinking glasses, books, vases, jewelry, coins, pipes, and so on). With origins in the Middle Ages and Ancient Graeco-Roman art, still-life painting emerged as a distinct genre and professional specialization in Western painting by the late 16th century, and has remained significant since then. Still life gives the artist more freedom in the arrangement of elements within a composition than do paintings of other types of subjects such as landscape or portraiture. Early still-life paintings, particularly before 1700, often contained religious and allegorical symbolism relating to the objects depicted. Some modern still life breaks the two-dimensional barrier and employs three-dimensional mixed media, and uses found objects, photography, computer graphics, as well as video and sound.
