In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by Alexandre-Edmond Becquerel. Though the premiere solar panels were too inefficient for even simple electric devices they were used as an instrument to measure light. The observation by Becquerel was not replicated again until 1873, when Willoughby Smith discovered that the charge could be caused by light hitting selenium. After this discovery, William Grylls Adams and Richard Evans Day published "The action of light on selenium" in 1876, describing the experiment they used to replicate Smith's results.
The earliest literature in India, composed between 1500 BCE and 1200 CE, was in the Sanskrit language. Major works of Sanskrit literature include the Rigveda (c. 1500 BCE – 1200 BCE), the epics: Mahābhārata (c. 400 BCE – 400 CE) and the Ramayana (c. 300 BCE and later); Abhijñānaśākuntalam (The Recognition of Śakuntalā, and other dramas of Kālidāsa (c. 5th century CE) and Mahākāvya poetry. In Tamil literature, the Sangam literature (c. 600 BCE – 300 BCE) consisting of 2,381 poems, composed by 473 poets, is the earliest work. From the 14th to the 18th centuries, India's literary traditions went through a period of drastic change because of the emergence of devotional poets like Kabīr, Tulsīdās, and Guru Nānak. This period was characterised by a varied and wide spectrum of thought and expression; as a consequence, medieval Indian literary works differed significantly from classical traditions. In the 19th century, Indian writers took a new interest in social questions and psychological descriptions. In the 20th century, Indian literature was influenced by the works of the Bengali poet and novelist Rabindranath Tagore, who was a recipient of the Nobel Prize in Literature.
More InfoTelevision broadcasting began in India in 1959 as a state-run medium of communication and expanded slowly for more than two decades. The state monopoly on television broadcast ended in the 1990s. Since then, satellite channels have increasingly shaped the popular culture of Indian society. Today, television is the most penetrative media in India; industry estimates indicate that as of 2012 there are over 554 million TV consumers, 462 million with satellite or cable connections compared to other forms of mass media such as the press (350 million), radio (156 million) or internet (37 million).
More InfoUntil the beginning of the first millennium CE, the ordinary dress of people in India was entirely unstitched. The arrival of the Kushans from Central Asia, circa 48 CE, popularised cut and sewn garments in the style of Central Asian favoured by the elite in northern India. However, it was not until Muslim rule was established, first with the Delhi sultanate and then the Mughal Empire, that the range of stitched clothes in India grew and their use became significantly more widespread. Among the various garments gradually establishing themselves in northern India during medieval and early-modern times and now commonly worn are: the shalwars and pyjamas both forms of trousers, as well as the tunics kurta and kameez. In southern India, however, the traditional draped garments were to see much longer continuous use.
More InfoFamily values are important in the Indian tradition, and multi-generational patriarchal joint families have been the norm in India, though nuclear families are becoming common in urban areas. An overwhelming majority of Indians, with their consent, have their marriages arranged by their parents or other family elders. Marriage is thought to be for life, and the divorce rate is extremely low, with less than one in a thousand marriages ending in divorce. Child marriages are common, especially in rural areas; many women wed before reaching 18, which is their legal marriageable age. Female infanticide in India, and lately female foeticide, have created skewed gender ratios; the number of missing women in the country quadrupled from 15 million to 63 million in the 50-year period ending in 2014, faster than the population growth during the same period, and constituting 20 percent of India's female electorate. Accord to an Indian government study, an additional 21 million girls are unwanted and do not receive adequate care. Despite a government ban on sex-selective foeticide, the practice remains commonplace in India, the result of a preference for boys in a patriarchal society. The payment of dowry, although illegal, remains widespread across class lines. Deaths resulting from dowry, mostly from bride burning, are on the rise, despite stringent anti-dowry laws.
More InfoAccording to a 2011 PricewaterhouseCoopers (PwC) report, India's GDP at purchasing power parity could overtake that of the United States by 2045. During the next four decades, Indian GDP is expected to grow at an annualised average of 8%, making it potentially the world's fastest-growing major economy until 2050. The report highlights key growth factors: a young and rapidly growing working-age population; growth in the manufacturing sector because of rising education and engineering skill levels; and sustained growth of the consumer market driven by a rapidly growing middle-class. The World Bank cautions that, for India to achieve its economic potential, it must continue to focus on public sector reform, transport infrastructure, agricultural and rural development, removal of labour regulations, education, energy security, and public health and nutrition.
