. Vedic period – The Vedic period was the period in Indian history during which the Vedas, the oldest scriptures of Hinduism, were composed. During the early part of the Vedic period, the Indo-Aryans settled into northern India, scholars consider Vedic civilisation to have been a composite of the Indo-Aryan and Harappan cultures. The end of the Vedic period witnessed the rise of large, around the beginning of the Common Era, the Vedic tradition formed one of the main constituents of the so-called Hindu synthesis. The commonly proposed period of earlier Vedic age is dated back to 2nd millennium BCE, after the collapse of the Indus Valley Civilisation, which ended c.1900 BCE, groups of Indo-Aryan peoples migrated into north-western India and started to inhabit the northern Indus Valley. The knowledge about the Aryans comes mostly from the Rigveda-samhita, which was composed between c and they brought with them their distinctive religious traditions and practices. The Vedic beliefs and practices of the era were closely related to the hypothesised Proto-Indo-European religion. According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the zone between the Zeravshan River and Iran. It was a mixture of old Central Asian and new Indo-European elements. At least 383 non-Indo-European words were borrowed from this culture, including the god Indra, Indra was the subject of 250 hymns, a quarter of the Rig Veda. He was associated more than any other deity with Soma, a stimulant drug probably borrowed from the BMAC religion and his rise to prominence was a peculiar trait of the Old Indic speakers. These migrations may have been accompanied with violent clashes with the people who inhabited this region. The Rig Veda contains accounts of conflicts between the Aryas and the Dasas and Dasyus, the Rig Veda describes Dasas and Dasyus as people who do not perform sacrifices or obey the commandments of gods. Their speech is described as mridhra which could variously mean soft, uncouth, hostile, other adjectives which describe their physical appearance are subject to many interpretations. Internecine military conflicts between the tribes of Vedic Aryans are also described in the Rig Veda. Most notable of such conflicts was the Battle of Ten Kings, which took place on the banks of the river Parushni. The battle was fought between the tribe Bharatas, led by their chief Sudas, against a confederation of ten tribes— Puru, Yadu, Turvasha, Anu, Druhyu, Alina, Bhalanas, Paktha, Siva, Vishanin. Bharatas lived around the regions of the river Saraswati, while Purus, their western neighbours. The other tribes dwelt north-west of the Bharatas in the region of Punjab, division of the waters of Ravi could have been a reason for the war

5. Writing – Writing is a medium of human communication that represents language and emotion through the inscription or recording of signs and symbols. In most languages, writing is a complement to speech or spoken language, Writing is not a language but a form of technology that developed as tools developed with human society. Within a language system, writing relies on many of the structures as speech, such as vocabulary, grammar and semantics. The result of writing is called text, and the recipient of text is called a reader. Motivations for writing include publication, storytelling, correspondence and diary, Writing has been instrumental in keeping history, maintaining culture, dissemination of knowledge through the media and the formation of legal systems. As human societies emerged, the development of writing was driven by pragmatic exigencies such as exchanging information, maintaining financial accounts, codifying laws, in both ancient Egypt and Mesoamerica writing may have evolved through calendrics and a political necessity for recording historical and environmental events. H. G. Wells argued that writing has the ability to put agreements, laws and it made the growth of states larger than the old city states possible. It made a continuous historical consciousness possible, the command of the priest or king and his seal could go far beyond his sight and voice and could survive his death. The major writing systems—methods of inscription—broadly fall into four categories, logographic, syllabic, alphabetic, another category, ideographic, has never been developed sufficiently to represent language. A sixth category, pictographic, is insufficient to represent language on its own, a logogram is a written character which represents a word or morpheme. A vast number of logograms are needed to write Chinese characters, cuneiform, and Mayan, where a glyph may stand for a morpheme, many logograms have an ideographic component. For example, in Mayan, the glyph for fin, pronounced ka, was used to represent the syllable ka whenever the pronunciation of a logogram needed to be indicated. In Chinese, about 90% of characters are compounds of an element called a radical with an existing character to indicate the pronunciation. However, such phonetic elements complement the elements, rather than vice versa. A syllabary is a set of symbols that represent syllables. A glyph in a syllabary typically represents a consonant followed by a vowel, or just a vowel alone, phonetically related syllables are not so indicated in the script. For instance, the syllable ka may look nothing like the syllable ki, syllabaries are best suited to languages with a relatively simple syllable structure, such as Japanese. Other languages that use syllabic writing include the Linear B script for Mycenaean Greek, Cherokee, Ndjuka, an English-based creole language of Surinam, most logographic systems have a strong syllabic component

6. Universe – The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, the size of the entire Universe is unknown. The earliest scientific models of the Universe were developed by ancient Greek and Indian philosophers and were geocentric, over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of gravitation, Sir Isaac Newton built upon Copernicuss work as well as observations by Tycho Brahe. Further observational improvements led to the realization that our Solar System is located in the Milky Way galaxy and it is assumed that galaxies are distributed uniformly and the same in all directions, meaning that the Universe has neither an edge nor a center. Discoveries in the early 20th century have suggested that the Universe had a beginning, the majority of mass in the Universe appears to exist in an unknown form called dark matter. The Big Bang theory is the prevailing cosmological description of the development of the Universe, under this theory, space and time emerged together 13. 799±0.021 billion years ago with a fixed amount of energy and matter that has become less dense as the Universe has expanded. After the initial expansion, the Universe cooled, allowing the first subatomic particles to form, giant clouds later merged through gravity to form galaxies, stars, and everything else seen today. Some physicists have suggested various multiverse hypotheses, in which the Universe might be one among many universes that likewise exist, the Universe can be defined as everything that exists, everything that has existed, and everything that will exist. According to our current understanding, the Universe consists of spacetime, forms of energy, the Universe encompasses all of life, all of history, and some philosophers and scientists suggest that it even encompasses ideas such as mathematics and logic. The word universe derives from the Old French word univers, which in turn derives from the Latin word universum, the Latin word was used by Cicero and later Latin authors in many of the same senses as the modern English word is used. Another synonym was ὁ κόσμος ho kósmos, synonyms are also found in Latin authors and survive in modern languages, e. g. the German words Das All, Weltall, and Natur for Universe. The same synonyms are found in English, such as everything, the cosmos, the world, the prevailing model for the evolution of the Universe is the Big Bang theory. The Big Bang model states that the earliest state of the Universe was extremely hot and dense, the model is based on general relativity and on simplifying assumptions such as homogeneity and isotropy of space. The Big Bang model accounts for such as the correlation of distance and redshift of galaxies, the ratio of the number of hydrogen to helium atoms. The initial hot, dense state is called the Planck epoch, after the Planck epoch and inflation came the quark, hadron, and lepton epochs. Together, these epochs encompassed less than 10 seconds of time following the Big Bang, the observed abundance of the elements can be explained by combining the overall expansion of space with nuclear and atomic physics. As the Universe expands, the density of electromagnetic radiation decreases more quickly than does that of matter because the energy of a photon decreases with its wavelength

7. Human – Modern humans are the only extant members of Hominina tribe, a branch of the tribe Hominini belonging to the family of great apes. Several of these hominins used fire, occupied much of Eurasia and they began to exhibit evidence of behavioral modernity around 50,000 years ago. In several waves of migration, anatomically modern humans ventured out of Africa, the spread of humans and their large and increasing population has had a profound impact on large areas of the environment and millions of native species worldwide. Humans are uniquely adept at utilizing systems of communication for self-expression and the exchange of ideas. Humans create complex structures composed of many cooperating and competing groups, from families. Social interactions between humans have established a wide variety of values, social norms, and rituals. These human societies subsequently expanded in size, establishing various forms of government, religion, today the global human population is estimated by the United Nations to be near 7.5 billion. In common usage, the word generally refers to the only extant species of the genus Homo—anatomically and behaviorally modern Homo sapiens. In scientific terms, the meanings of hominid and hominin have changed during the recent decades with advances in the discovery, there is also a distinction between anatomically modern humans and Archaic Homo sapiens, the earliest fossil members of the species. The English adjective human is a Middle English loanword from Old French humain, ultimately from Latin hūmānus, the words use as a noun dates to the 16th century. The native English term man can refer to the species generally, the species binomial Homo sapiens was coined by Carl Linnaeus in his 18th century work Systema Naturae. The generic name Homo is a learned 18th century derivation from Latin homō man, the species-name sapiens means wise or sapient. Note that the Latin word homo refers to humans of either gender, the genus Homo evolved and diverged from other hominins in Africa, after the human clade split from the chimpanzee lineage of the hominids branch of the primates. The closest living relatives of humans are chimpanzees and gorillas, with the sequencing of both the human and chimpanzee genome, current estimates of similarity between human and chimpanzee DNA sequences range between 95% and 99%. The gibbons and orangutans were the first groups to split from the leading to the humans. The splitting date between human and chimpanzee lineages is placed around 4–8 million years ago during the late Miocene epoch, during this split, chromosome 2 was formed from two other chromosomes, leaving humans with only 23 pairs of chromosomes, compared to 24 for the other apes. There is little evidence for the divergence of the gorilla, chimpanzee. Each of these species has been argued to be an ancestor of later hominins
