Colorado River

The Colorado River is the principal river of the Southwestern United
States and northwest Mexico. Rising in the western Rocky Mountains, the
1,450-mile (2,330 km) river drains a vast arid region of the Colorado
Plateau and the Mojave and Sonoran Deserts as it heads towards the Gulf
of California. Known for its dramatic scenery (Horseshoe Bend pictured)
and its whitewater, the Colorado carves numerous gorges, including the
Grand Canyon in northern Arizona. For 8,000 years, the Colorado Basin
was only sparsely populated by Native Americans, though some of their
ancient civilizations employed advanced irrigation techniques. Even
after becoming part of the U.S. in the 1800s, the Colorado River country
remained extremely remote until John Wesley Powell's 1869 river-running
expedition, which began to open up the river for future development.
Since the completion of Hoover Dam in 1935, the Colorado has been tamed
by an extensive system of dams and canals, providing for irrigation,
cities, and hydropower. Today the Colorado supports 40 million people in
seven U.S. and two Mexican states; with every drop of its water
allocated, it no longer reaches the sea except in years of heavy runoff.

Web search engine

A web search engine is a software system that is desined to search for information on the World Wide Web.The search results are generally presented in 
a line of results often referred to as search engine reults pages (SERPs).The
information may be a mix of web pages,images,and other types of files.Some 
search engines also mine data available in databases or open directories. Unlike 
web directories,which are maintained only by human editors, search engines also
maintain real-time information by running an algorithm on a web crawler.

nebular hypothesis

The nebular hypothesis is the most widely accepted model in cosmogony
explaining the formation and evolution of the Solar System, which
suggests that it formed from nebulous material in space. The hypothesis
offers explanations for some of the Solar System's properties, including
the nearly circular and coplanar orbits of the planets, and their motion
in the same direction as the Sun's rotation. According to the
hypothesis, Sun-like stars form over about 100 million years, in
massive, gravitationally unstable clouds of molecular hydrogen (giant
molecular clouds). Matter coalesces to smaller, denser clumps within,
which then proceed to both rotate and collapse, forming stars. Star
formation produces a gaseous protoplanetary disk around the young star,
which may give birth to planets (protoplanetary disk pictured in the
Orion Nebula). The formation of planetary systems is thought to be a
natural result of star formation, with dense terrestrial planets forming
closer to the star and colder giant planets forming further away, beyond
the so-called frost line. Originally applied only to our own Solar
System, the nebular hypothesis is now thought to be at work throughout
the universe.

Oscar Wilde

Oscar Fingal O'Flahertie Wills Wilde (16 October 1854 – 30 November 1900) was an Irish writer and poet. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. Today he is remembered for his epigrams, his novel The Picture of Dorian Gray, his plays, and the circumstances of his imprisonment and early death. In the latter half of the 20th century he became a gay icon.^[1]

Wilde's parents were successful Anglo-Irish Dublin intellectuals. Their son became fluent in French and German early in life. At university, Wilde read Greats; he proved himself to be an outstanding classicist, first atDublin, then at Oxford. He became known for his involvement in the rising philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde moved to London into fashionable cultural and social circles. As a spokesman for aestheticism, he tried his hand at various literary activities: he published a book of poems, lectured in the United States and Canada on the new "English Renaissance in Art", and then returned to London where he worked prolifically as a journalist. Known for his biting wit, flamboyant dress and glittering conversation, Wilde became one of the best-known personalities of his day.

At the turn of the 1890s, he refined his ideas about the supremacy of art in a series of dialogues and essays, and incorporated themes of decadence, duplicity, and beauty into his only novel, The Picture of Dorian Gray(1890). The opportunity to construct aesthetic details precisely, and combine them with larger social themes, drew Wilde to write drama. He wrote Salome (1891) in French in Paris but it was refused a licence for England due to the absolute prohibition of Biblical subjects on the English stage. Unperturbed, Wilde produced four society comedies in the early 1890s, which made him one of the most successful playwrights of late Victorian London.

At the height of his fame and success, while his masterpiece, The Importance of Being Earnest (1895), was still on stage in London, Wilde had the Marquess of Queensberry prosecuted for libel. The Marquess was the father of Wilde's lover, Lord Alfred Douglas. The charge carried a penalty of up to two years in prison. The trial unearthed evidence that caused Wilde to drop his charges and led to his own arrest and trial for gross indecency with other men. After two more trials he was convicted and imprisoned for two years' hard labour. In 1897, in prison, he wrote De Profundis, which was published in 1905, a long letter which discusses his spiritual journey through his trials, forming a dark counterpoint to his earlier philosophy of pleasure. Upon his release he left immediately for France, never to return to Ireland or Britain. There he wrote his last work, The Ballad of Reading Gaol (1898), a long poem commemorating the harsh rhythms of prison life. He died destitute in Paris at the age of 46.

Abraham Lincoln

Abraham Lincoln ⁱ/ˈeɪbrəhæm ˈlɪŋkən/ (February 12, 1809 – April 15, 1865) was the 16th president of the United States, serving from March 1861 until his assassination in April 1865. Lincoln led the United States through its Civil War—its bloodiest war and its greatest moral, constitutional and political crisis.^[1][2] In doing so, he preserved the Union, abolished slavery, strengthened the federal government, and modernized the economy.

Reared in a poor family on the western frontier, Lincoln was a self-educated lawyer in Illinois, a Whig Party leader, state legislator during the 1830s, and a one-term member of the Congress during the 1840s. He promoted rapid modernization of the economy through banks, canals, railroads and tariffs to encourage the building of factories; he opposed the war with Mexico in 1846. After a series of highly publicized debates in 1858, during which Lincoln spoke out against the expansion of slavery, he lost the U.S. Senate race to his archrival, Democrat Stephen A. Douglas.

Lincoln, a moderate from a swing state, secured the Republican Party presidential nomination in 1860. With very little support in the slave states, Lincoln swept the North and was elected president in 1860. His election prompted seven southern slave states to form the Confederacy before he took the office. No compromise or reconciliation was found regarding slavery.

When the North enthusiastically rallied behind the Union after the Confederate attack on Fort Sumter on April 12, 1861, Lincoln concentrated on the military and political dimensions of the war effort. His primary goal was always to reunite the nation. He suspended habeas corpus, arresting and temporarily detaining thousands of suspected secessionists in the border states without trial. Lincoln averted potential British intervention by defusing the Trent Affair in late 1861. His complex moves toward ending slavery centered on the Emancipation Proclamation in 1863, using the Army to protect escaped slaves, encouraging the border states to outlaw slavery, and helping push through Congress theThirteenth Amendment to the United States Constitution, which permanently outlawed slavery. Lincoln closely supervised the war effort, especially the selection of top generals, including his most successful general Ulysses S. Grant. He made the major decisions on Union war strategy. Lincoln's Navy set up a naval blockade that shut down the South's normal trade, helped take control of Kentucky and Tennessee, and gained control of the Southern river system using gunboats. Lincoln tried repeatedly to capture the Confederate capital at Richmond; each time a general failed, Lincoln substituted another, until finally Grant succeeded in 1865.

An exceptionally astute politician deeply involved with power issues in each state, Lincoln reached out to "War Democrats" (who supported the North against the South), and managed his own re-election in the1864 presidential election. As the leader of the moderate faction of the Republican party, Lincoln confronted Radical Republicans who demanded harsher treatment of the South, War Democrats who called for more compromise, antiwar Democrats called Copperheads who despised him, and irreconcilable secessionists who plotted his death. Politically, Lincoln fought back by pitting his opponents against each other, by appealing to the American people with his powers of oratory, and by carefully planned political patronage.^[3] His Gettysburg Address of 1863 became an iconic statement of America's dedication to the principles of nationalism, republicanism, equal rights, liberty, and democracy. Lincoln held a moderate view of Reconstruction, seeking to reunite the nation speedily through a policy of generous reconciliation in the face of lingering and bitter divisiveness. Six days after the surrender of Confederate commanding general Robert E. Lee, Lincoln was assassinated by John Wilkes Booth, a noted actor and Confederate sympathizer.

Lincoln has been consistently ranked both by scholars and the public as one of the greatest U.S. presidents.

Megadeth

Megadeth is a thrash metal band from Los Angeles, California.
 The group was formed in 1983 by guitarist Dave Mustaine and 
bassist David Ellefson. It is credited as one of thrash metal's "big four" with
Anthrax, Metallica and Slayer, responsible for the genre's development
and popularization. Megadeth's music features fast rhythm sections and
complex arrangements; themes of death, war, politics and religion are
prominent in the lyrics. The success of its debut album on an
independent label led to Megadeth signing with Capitol Records. The
band's first major-label album, Peace Sells... but Who's Buying? (1986),
greatly influenced the underground metal scene; albums and worldwide
tours in the 1990s brought Megadeth public recognition. The group has
sold 50 million records worldwide, earned U.S. platinum certification
for six of its fourteen studio albums, and received eleven Grammy
nominations. The band's mascot, Vic Rattlehead, regularly appears on
album artwork and since 2010 in live shows. The group has experienced
controversy over its musical approach and lyrics: concerts have been
canceled, albums banned, and MTV refused to play two videos that it
considered to condone suicide.

MANTRA

The Om syllable is considered a mantra in its own right in Vedanta school of Hinduism.

"Mantra" (Sanskrit मंत्र) means a sacred utterance, numinous sound, or a syllable, word, phonemes, or group of words believed by some to have psychological and spiritual power.Mantra may or may not be syntactic or have literal meaning; the spiritual value of mantra comes when it is audible, visible, or present in thought.

Earliest mantras were composed in Vedic times by Hindus in India, and those are at least 3000 years old.Mantras are now found in various schools of Hinduism, Buddhism, Jainism and Sikhism.Similar hymns, chants, compositions and concepts are found in Zoroastrianism,Taoism, Christianity and elsewhere.

The use, structure, function, importance and types of mantras vary according to the school and philosophy of Hinduism and of Buddhism. Mantras serve a central role in the tantric school of Hinduism.In this school, mantras are considered equivalent to deities, a sacred formula and deeply personal ritual, and considered to be effective only after initiation. However, in other schools of Hinduism, Buddhism, Jainism or Sikhism, this is not so.

Mantras come in many forms, including ṛc (verses from Rigveda for example) and sāman (musical chants from the Sāmaveda for example).They are typically melodic, mathematically structured meters, resonant with numinous qualities. At its simplest, the word ॐ (Aum, Om) serves as a mantra. In more sophisticated forms, they are melodic phrases with spiritual interpretations such as human longing for truth, reality, light, immortality, peace, love, knowledge and action.  In other forms, they are literally meaningless, yet musically uplifting and spiritually meaningful.
