Tamil /ˈtæmɪl/ (தமிழ், tamiḻ, [t̪ɐmɨɻ] ?) is a Dravidian language predominantly spoken by the Tamil people of India and northern Sri Lanka, and also by the Tamil diaspora. Tamil is an official language of two countries, Singapore and Sri Lanka, and has official status in the Indian state of Tamil Nadu and the Indian Union Territory of Puducherry. It is also used as one of the languages of education in Malaysia, along with English, Malay and Mandarin. In India, outside of Tamil Nadu and Puducherry, Tamil is also spoken in the states of Kerala, Puducherry and Andaman and Nicobar Islands as a secondary language and by minorities in Karnataka and Andhra Pradesh. It is one of the 22 scheduled languages of India and was the first Indian language declared as a classical language, which was done by the Government of India in 2004. The language is also spoken by Tamil minorities in Malaysia, the United Arab Emirates, the United States, United Kingdom, Mauritius, Canada,South Africa,Fiji,Germany, the Philippines, the Netherlands, Indonesia and France, as well as smaller emigrant communities elsewhere.
The Tamil script (தமிழ் அரிச்சுவடி tamiḻ ariccuvaṭi) is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, and elsewhere to write the Tamil language, as well as to write the liturgical language Sanskrit, using consonants and diacritics not represented in the Tamil alphabet. Certain minority languages such as Saurashtra, Badaga, Irula, and Paniya language are also written in the Tamil script.
The Tamil script has 12 vowels (உயிரெழுத்து uyireḻuttu "soul-letters"), 18 consonants (மெய்யெழுத்து meyyeḻuttu "body-letters") and one special character, the ஃ (ஆயுத எழுத்து). ஃ is pronounced as "akku" or "அக்கு" and is classified in Tamil grammar as being neither a consonant nor a vowel. However, it is listed at the end of the vowel set. The script is syllabic, not alphabetic. The complete script, therefore, consists of the thirty-one letters in their independent form, and an additional 216 combinant letters representing a total 247 combinations (உயிர்மெய்யெழுத்து uyirmeyyeḻuttu) of a consonant and a vowel, a mute consonant, or a vowel alone. These combinant letters are formed by adding a vowel marker to the consonant. Some vowels require the basic shape of the consonant to be altered in a way that is specific to that vowel. Others are written by adding a vowel-specific suffix to the consonant, yet others a prefix, and finally some vowels require adding both a prefix and a suffix to the consonant. In every case the vowel marker is different from the standalone character for the vowel.
Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
The word nature is derived from the Latin word natura, or "essential qualities, innate disposition", and in ancient times, literally meant "birth".Natura is a Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers, and has steadily gained currency ever since. This usage continued during the advent of modern scientific method in the last several centuries.
Nature is a British interdisciplinary scientific journal, first published on 4 November 1869. It was ranked the world's most cited scientific journal by the Science Edition of the 2010 Journal Citation Reports, is ascribed an impact factor of approximately 42.4, and is widely regarded as one of the few remaining academic journals that publishes original research across a wide range of scientific fields.Nature claims an online readership of about 3 million unique readers per month. The journal has a weekly circulation of around 53,000 but studies have concluded that on average a single copy is shared by as many as eight people.
Research scientists are the primary audience for the journal, but summaries and accompanying articles are intended to make many of the most important papers understandable to scientists in other fields and the educated public. Towards the front of each issue are editorials, news and feature articles on issues of general interest to scientists, including current affairs, science funding, business, scientific ethics and research breakthroughs. There are also sections on books and arts. The remainder of the journal consists mostly of research papers (articles or letters), which are often dense and highly technical. Because of strict limits on the length of papers, often the printed text is actually a summary of the work in question with many details relegated to accompanying supplementary material on the journal's website.
Mother Nature (sometimes known as Mother Earth or the Earth-Mother), is a common personification of nature that focuses on the life-giving and nurturing aspects of nature by embodying it ,in the form of the mother.
The word "nature" comes from the Latin word, "natura," meaning birth or character (see nature (innate)). In English its first recorded use (in the sense of the entirety of the phenomena of the world) was in 1266 A.D.. "Natura", and the personification of Mother Nature, was widely popular in the Middle Ages. As a concept, seated between the properly divine and the human, it can be traced to Ancient Greece, though Earth (or "Eorthe" in the Old English period) may have been personified as a goddess. The Norse also had a goddess called Jord (or Earth).
The earliest written dated literal references to the term "Mother Earth" occur in Mycenaean Greek. Ma-ka (transliterated as ma-ga), "Mother Gaia", written in Linear B syllabic script (13th or 12th century BC). The various myths of nature goddesses such as Inanna/Ishtar (myths and hymns attested on Mesopotamian tablets as early as the 3rd millennium BC) show that the personification of the creative and nurturing sides of nature as female deities has deep roots. In Greece, the pre-Socratic philosophers had "invented" nature when they abstracted the entirety of phenomena of the world as singular: physis, and this was inherited by Aristotle. Later medieval Christian thinkers did not see nature as inclusive of everything, but thought that she had been created by God; her place lay on earth, below the unchanging heavens and moon. Nature lay somewhere in the center, with agents above her (angels), and below her (demons and hell). For the medieval mind she was only a personification, not a goddess.
