Etymology of India

India, as a country and nation, has three principal names, in both official and popular usage, each of which is historically and culturally important. All three originally designated a single entity comprise all the modern nations of the Indian subcontinent. The first Article of the Constitution of India, which deals with the official name, states that "India, that is Bharat, shall be a union of states." Thus, not only in usage but officially India and Bharat are both accorded primary status? The name India is derived from the river Indus.

The innovative name of the river came from the fact that in the north-west of the subcontinent, there are seven main tributaries of the one river. The local inhabitants therefore called it Sapta-Sindhu, meaning the seven rivers. As the seven tributaries are part of the one river, the whole river system came to be known in time as Sindhu. In general, Sindhu also means any river or water body in Sanskrit.

Heat wave

A heat wave is a prolonged period of extremely hot weather, which may be accompanied by high humidity. There is no universal definition of a heat wave the term is relative to the usual weather in the area. Temperatures that people from a hotter climate believe normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area. The term is applied both to routine weather variation and to extraordinary spells of heat which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, and widespread power outages due to increased use of air conditioning.

Heat waves often occur for the period of the Dog Days of summer; indeed the French term canicule, denoting the general phenomenon of a heat wave, derives from the Italian canicula applied to the star Sirius, also known as the "Dog Star."

Some regions of the globe are more susceptible to heat waves than others, such as Mediterranean-type climates with a summer dry spell which becomes much hotter than usual during certain years

Hinduism Dharma also known as Vaidika is a religion or philosophy that originated from the Indian subcontinent and nearby close areas. The term Hinduism is heterogeneous, as Hinduism consists of several schools of thought. It encompasses many religious rituals that widely vary in practice, as well as many diverse sects and philosophies. Many Hindus, influenced by Advaita philosophy, venerate an array of deities, considering them manifestations of the one supreme monistic Cosmic Spirit, Brahman, while many others focus on a singular concept of Brahman, as in Vaishnavism, Saivism and Shaktism.

Hinduism is the third major religion in the world, with approximately 900 million adherents, of whom approximately 890 million live in India. It is also the oldest known religion in the world today. Unlike many other religions, Hinduism has no main founder. It also has no single holy book — it has many, with all pointing to the same Truth - its original scriptures were the four Vedas, but as time has passed, many other scriptures have also emerged.

Peripheral layout

The very old city inside the walls covers about four percent of the current municipality's 582 square miles. The old city is the negligible of Rome's twelve administrative zones. The walled city center is made up of 22 rioni, nearby it are 35 quartieri urbani, and within the city restrictions are six large suburban. The comune of Rome positioned outside the municipal boundaries about doubles the area of the real city.

The belt highway known as Grande Raccordo Anulare describes an enormous circle around the wealth, about six miles out from the city centre; unlike most Italian highways, the G.R.A. is toll-free. The sphere ties together the antique roads to lead to Rome: the Via Flaminia, the Via Aurelia and Via Appia. Large amounts of modern dwelling buildings are located in the districts outside the centre, where current architecture has not gone unnoticed. Many road frontages and show windows often change to keep up with the times and the Romans have succeeded in harmonising the old and the fresh.

Clothing as social message

Social messages sent by clothing, garnishes, and decorations can involve social status, profession, ethnic and spiritual affiliation, marital status and sexual availability, etc. Humans must know the code in order to be familiar with the message transmitted. If different groups read the same item of clothing or decoration with different meanings, the wearer may aggravate unanticipated and/or unwanted responses.

The manner of intentionally constructing, assembling, and wearing clothing to convey a social message in any culture is governed by current fashion. The rate at which manner changes varies; easily modified styles in wearing or accessorizing clothes can alter in months, even days, in small groups or in media-influenced modern societies. More extensive changes, that may require more time, money, or effort to effect, may cover generations. When fashion changes, messages from clothing change.

Myths and legends The Heel Stone was once known as "Friar's Heel." A folk tale, which cannot be dated earlier than the seventeenth century, relates the origin of the name of this stone:The Devil bought the stones from a woman in Ireland, wrapped them up, and brought them to Salisbury plain. One of the stones fell into the Avon, the rest were carried to the plain. The Devil then cried out, "No-one will ever find out how these stones came here." A friar replied, "That's what you think!," whereupon the Devil threw one of the stones at him and struck him on the heel. The stone stuck in the ground and is still there.Some claim "Friar's Heel" is a corruption of "Freyja's He-ol" or "Freyja Sul", from the Nordic goddess Freyja and the Welsh words for "way" and "Friday" respectively.

Galaxy Evolution
Studies show that the Milky Way Galaxy is moving towards the nearby Andromeda Galaxy at about 130 km/s, and depending upon the lateral movements, the two may collide in about five to six billion years. Such galaxy collisions are fairly common, especially in dense galaxy clusters. Given the distances between the stars, the great majority of stellar systems in colliding galaxies will be unaffected. However, gravitational stripping of the interstellar gas and dust that makes up the spiral arms will produce a long train of stars, similar to that seen in NGC 250 or the Antennae Galaxies.Although the Milky Way has never collided with a galaxy as large as Andromeda before, evidence of past collisions of the Milky Way with smaller dwarf galaxies is increasing.Spiral galaxies, like the Milky Way, only produce new generations of stars as long as they continue to have dense molecular clouds of interstellar hydrogen in their spiral arms. Elliptical galaxies are already largely devoid of this gas and so form no new stars. However, the supply of star-forming material is finite; as stars convert hydrogen into heavier elements, fewer stars will form.After the end of stellar formation in under one hundred billion years, the "stellar age" will come to an end after about ten trillion to one hundred trillion years, as the smallest longest-lived stars in our astrosphere, tiny red dwarfs begin to fade. At the end of the stellar age galaxies will comprise compact objects: brown dwarfs, black dwarfs, cooling white dwarfs, neutron stars, and black holes. Eventually, as a result of gravitational relaxation, all stars will either fall into the central supermassive black hole of the galaxies, or be flung into the depths of intergalactic space as a result of collisions.

Shopping is considered a leisure activity of psychological interest. Shopping engages selection and purchase."Window shopping" is an American/English phrase meaning to seem into glass windows of a shop for amusement and imagine purchasing items without
actually purchasing, possibly just to pass the time among other activities, or planning a purchase.Shops are divided into numerous categories of stores
which sell a selected set of goods or services.Many stores are part of a chain: a number of similar shops with the same name selling the same products in
dissimilar locations. The shops may be owned by one company, or there may be a franchising corporation that has franchising agreements with the shop
owners. Several shops sell second-hand goods. Often the public can also sell goods to such shops. In other cases, particularly in the case of a nonprofit shop, the
public contribute goods to the shop to be sold. In give away shops goods can be in use for free. In Antique shops the public can discover goods that are
older and unique.

Metamorphosis is a procedure in biology by which an individual physically expands after birth or hatching, that involves important change in form as well as growth and separation. It usually accompanies a change of habitat or of habits, but may occur without such change. Insects, amphibians and some additional organisms undergo metamorphosis.

Change of habits or habitat
Many insects and amphibians undertake metamorphosis with a important change in habits and habitat. undeveloped dragonflies are aquatic, though the adults are flying insects, and frogs undergo a metamorphosis from an water tadpole to an amphibious adult form. Change of habits is illustrated by the renovation of the free-swimming young of many water invertebrates into sessile adults (eg sea squirts), and the development of butterflies and moths from caterpillars with crushing mouthparts into flying insects with sucking mouthparts.
By compare, many crustacean genus undergo significant physical metamorphosis without altering habits or habitat significantly.
It was once thinking that, in cases where the animal's habitat remains unchanged, metamorphosis tracked a series of forms representing evolutionary ancestors of the species in question (see ontogeny recapitulates phylogeny), but this is no longer thought to be factual.
