Sir Isaac Newton PRS MP  25 December 1642 – 20 March 1726/7 was an English physicist and mathematician (described in his own day as a "natural philosopher") who is widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution. His book Philosophiæ Naturalis Principia Mathematica ("Mathematical Principles of Natural Philosophy"), first published in 1687, laid the foundations for classical mechanics. Newton made seminal contributions to optics, and he shares credit with Gottfried Leibniz for the development of calculus. Newton's Principia formulated the laws of motion and universal gravitation, which dominated scientists' view of the physical universe for the next three centuries. By deriving Kepler's laws of planetary motion from his mathematical description of gravity, and then using the same principles to account for the trajectories of comets, the tides, the precession of the equinoxes, a

The Empire State Building is a 102-story skyscraper located in Midtown Manhattan, New York City, on Fifth Avenue between West 33rd and 34th Streets. It has a roof height of 1,250 feet (381 m), and with its antenna spire included, it stands a total of 1,454 feet (443 m) high. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for nearly 40 years, from its completion in early 1931 until the topping out of the original World Trade Center's North Tower in late 1970. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York, until One World Trade Center reached a greater height in April 2012.The Empire State Building is currently the fifth-tallest completed skyscraper in the United States and the 25th-tallest in the world. It is also the fifth-tallest freestanding structure in the Americas. When measured by pinnacle height, it is the fourth-tallest building in the U

The Moscow Kremlin usually referred to as the Kremlin, is a fortified complex at the heart of Moscow, overlooking the Moskva River to the south, Saint Basil's Cathedral and Red Square to the east, and the Alexander Garden to the west. It is the best known of the kremlins (Russian citadels) and includes five palaces, four cathedrals, and the enclosing Kremlin Wall with Kremlin towers. The complex serves as the official residence of the President of the Russian Federation. The name Kremlin means "fortress inside a city", and is often also used as a metonym to refer to the government of the Russian Federation in a similar sense to how the White House is used to refer to the Executive Office of the President of the United States. It had previously been used to refer to the government of the Soviet Union (1922–1991) and its highest members (such as general secretaries, premiers, presidents, ministers, and commissars). "Kremlinology" refers to the study of Sovie

Sri Guru Granth Sahib (Punjabi (Gurmukhi): ਗੁਰੂ ਗ੍ਰੰਥ ਸਾਹਿਬ, pronounced is the central religious text of Sikhism, considered by Sikhs to be the final, sovereign guru among the lineage of 10 Sikh Gurus of the religion.It is a voluminous text of 1430 Angs (pages), compiled and composed during the period of Sikh gurus from 1469 to 1708 and is a collection of hymns (Shabad) or Baani describing the qualities of God and the necessity for meditation on God's nām (holy name). Guru Gobind Singh (1666–1708), the tenth guru, after adding Guru Tegh Bahadur's bani to the Adi Granth,affirmed the sacred text as his successor. The text is the holy scripture of the Sikhs, regarded as the teachings of the Ten Gurus.The role of Guru Granth Sahib as a source or guide of prayer is pivotal in Sikh worship. The Adi Granth, the first rendition, was first compiled by the fifth Sikh guru, Guru Arjan (1563–1606), from hymns of the first five Sikh gurus and 15 other great saints, or bhagats, includ

Saroops of Sri Guru Granth Sahib again desecrated in village Bath of Distt.TARN TARAN, Punjab (October 18, 2015)—Following a successful Punjab shut down call on October 15 in protest of sacrilege of Sri Guru Granth Sahib Ji in village Bargadi (Kotkapura), another incident lamented the Sikh circles today. About 30 angs of Sri Guru Granth Sahib were reportedly found torn in Gurdwara Sahib of village Bath situated on Tarn Taran – Khadoor Sahib Road. The incident came into light when a woman went to Gurdwara Sahib at around 2.30 PM. When she began to recite gurbani, she found as many as 30 pages of the bir of Guru Granth Sahib torn. She made a noise as soon as she viewed the sacrilege of Holy Scripture.  Consequently wave of anger gripped the village and the outraged Sikh devotees blocked the two way communication of vehicles on Tarn Taran – Khadoor Sahib Road by parking their Tractor-Trolleys. Another parallel Road connecting Tarn Taran and Goindwal Sahib Sahib was also blocked

The Louvre or the Louvre Museum is one of the world's largest museums and a historic monument in Paris, France. A central landmark of the city, it is located on the Right Bank of the Seine in the 1st arrondissement (ward). Nearly 35,000 objects from prehistory to the 21st century are exhibited over an area of 60,600 square metres (652,300 square feet). The Louvre is the world's most visited museum, receiving more than 9.7 million visitors in 2012. The museum is housed in the Louvre Palace, originally built as a fortress in the late 12th century under Philip II. Remnants of the fortress are visible in the basement of the museum. The building was extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection, including, from 1692, a collection of ancient Greek and Roman sculpture. In 1692, the building was occupied by the Académie des Inscri

The history of Earth concerns the development of the planet Earth from its formation to the present day.Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. Earth formed around 4.54 billion years ago by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and ocean, but the atmosphere contained almost no oxygen and would have been toxic to humans and most modern life. Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism. One very large collision is thought to have been responsible for forming the Moon. Over time, the planet cooled and formed a solid crust, allowing liquid water to exist on the surface. The first life forms appeared between 3.8 and 3.5 billion

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Flowers give rise to fruit and seeds. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen . In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source

The Harmandir Sahib also Darbar Sahib and informally referred to as the "Golden Temple", is the holiest Sikh gurdwara located in the city of Amritsar, Punjab, India. The city was founded in 1574 by the fourth Sikh guru, Guru Ram Das. The Harmandir Sahib was designed by the fifth guru, Guru Arjan, who had the cornerstone laid by the Muslim Sufi saint Sai Hazrat Mian Mir on 28 December 1588. Guru Arjan completed the Adi Granth, the holy scripture of Sikhism, in 1604 and installed it in the gurdwara. There are four doors to get into the Harmandir Sahib, which symbolise the openness of the Sikhs towards all people and religions. The present-day gurdwara was rebuilt in 1764 by Jassa Singh Ahluwalia with the help of other Sikh Misls. In the early nineteenth century, Maharaja Ranjit Singh secured the Punjab region from outside attack and covered the upper floors of the gurdwara with gold, which gives it its distinctive appearance and its English name. The Harimandir Sahib is

A representation of the exchanges of energy between the source (the Sun), the Earth's surface, the Earth's atmosphere, and the ultimate sink outer space. The ability of the atmosphere to capture and recycle energy emitted by the Earth surface is the defining characteristic of the greenhouse effect. The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be in the absence of its atmosphere.If a planet's atmosphere contains radiatively active gases (i.e., greenhouse gases) the atmosphere radiates energy in all directions. Part of this radiation is directed towards the surface, warming it. On Earth, solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface. The surface itself emits energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases in the atmosph
