Tree

In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands 115.6 m (379 ft) high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world.[1][2] A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots. The shoots typically bear leaves, which capture light energy and convert it into sugars by photosynthesis, providing the food for the tree's growth and development. Flowers and fruit may also be present, but some trees, such as conifers, instead have pollen cones and seed cones; others, such as tree ferns, produce spores instead.

Sea

A sea is a large body of salt water that is surrounded in whole or in part by land.More broadly, the sea (with the definite article) is the interconnected system of Earth's salty, oceanic waters considered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since prehistory, the modern scientific study of the sea oceanographydates broadly to the British Challenger expedition of the 1870s The sea is conventionally divided into up to five large oceanic sections including the IHO's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean smaller, second-order sections, such as the Mediterranean, are known as seas. Owing to the present state of continental drift, the Northern Hemisphere is now fairly equally divided between land and sea (a ratio of about 2:3) but the South is overwhelmingly oceanic (1:4.7)Salinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature. Surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth (the Coriolis effect).

Sky Blue

ky blue is the name of a colour, first recorded in English in the 1729 Cyclopædia of Ephraim Chambers.[1] Prior to the Chambers reference, the colour had first been used in 1585 in a book by Nicolas De Nicolay where he stated "the tulbant of the merchant must be skie coloured Celeste (pronounced che-les-te in Italian se-lest in English) is the colloquial name for the pale turquoise blue colour associated with Italian bicycle manufacturer Bianchi S.p.A and sometimes known as Bianchi Green. In Italian, as the name indicates (Celestial), it is an attempt to reproduce the colour of clear skies. In English, this colour may also be referred to as Italian sky blue. Bleu celeste ("sky blue") is a rarely occurring tincture in heraldry (not being one of the seven main colours or metals or the three "staynard colours"). This tincture is sometimes also called ciel or simply celeste. It is depicted in a lighter shade than the range of shades of the more traditional tincture azure, which is the standard blue used in heraldry.

Peacoke hypotheses

Multiple hypotheses attempt to explain the evolution of female choice. Some of these suggest direct benefits to females, such as protection, shelter, or nuptial gifts that sway the female's choice of mate. Another hypothesis is that females choose mates with good genes. Males with more exaggerated secondary sexual characteristics, such as bigger, brighter peacock trains, tend to have better genes in the peahen's eyes.[6] These better genes will directly benefit her offspring, as well as her fitness and reproductive success. Runaway selection also seeks to clarify the evolution of the peacock's train. In runaway sexual selection, linked genes in males and females code for sexually dimorphic traits in males, and preference for those traits in females.[7] The close spatial association of alleles for loci involved in the train in males, and for preference for more exuberant trains in females, on the chromosome (linkage disequilibrium) causes a positive feedback loop that exaggerates both the male traits and the female preferences. Another hypothesis is sensory bias, in which females have a preference for a trait in a non-mating context that becomes transferred to mating. Multiple causality for the evolution of female choice is also possible. Work concerning female behavior in many species of animals has sought to confirm Darwin's basic idea of female preference for males with certain characteristics as a major force in the evolution of species.[8] Females have often been shown to distinguish small differences among potential mates, and to prefer mating with individuals bearing the most exaggerated characters.[9] In some cases, those males have been shown to be more healthy and vigorous, suggesting that the ornaments serve as markers indicating the males' abilities to survive and, thus, their genetic qualities.

Peacock

The Indian peacock has iridescent blue and green plumage. The peacock "tail", known as a "train", consists not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail. Both sexes of all species have a crest atop the head. The Indian peahen has a mixture of dull grey, brown, and green in her plumage. The female also displays her plumage to ward off female competition or signal danger to her young. The green peafowl differs from the Indian peafowl in that the male has green and gold plumage with black wings with a sheen of blue. Unlike the Indian peafowl, the green peahen is similar to the male, only having shorter upper tail coverts, a more coppery neck, and overall less iridescence.The Congo peacock male does not display his covert feathers, but uses his actual tail feathers during courtship displays. These feathers are much shorter than those of the Indian and green species, and the ocelli are much less pronounced. Females of the Indian and African species are dull grey and/or brown. Chicks of both sexes in all the species are cryptically coloured. They vary between yellow and tawny, usually with patches of darker brown or light tan and "dirty white" ivory.

Nataraja God

The dance of Shiva in Tillai, the traditional name for Chidambaram, forms the motif for all the depictions of Shiva as Nataraja. He is also known as "Sabesan" which splits as "Sabayil aadum eesan" in Tamil which means "The Lord who dances on the dais". The form is present in most Shiva temples in South India, and is the prime deity in the famous Thillai Nataraja Temple at Chidambaram.
The sculpture is usually made in bronze, with Shiva dancing in an aureole of flames, lifting his left leg (or in rare cases, the right leg) and balancing over a demon or dwarf (Muyalaka) who symbolizes ignorance. It is a well known sculptural symbol in India and popularly used as a symbol of Indian culture.
The two most common forms of Shiva's dance are the Lasya (the gentle form of dance), associated with the creation of the world, and the Tandava (the violent and dangerous dance), associated with the destruction of weary worldviews – weary perspectives and lifestyles. In essence, the Lasya and the Tandava are just two aspects of Shiva's nature; for he destroys in order to create, tearing down to build again.
