BengalBengal (bɛnˈɡɔːl ; বাংলা/বঙ্গ, ˈbɔŋgo) is a historical geographical, ethnolinguistic and cultural term referring to the eastern part of the Indian subcontinent at the apex of the Bay of Bengal. The region of Bengal proper is divided between modern-day Bangladesh and the Indian state of West Bengal. The Indian states of Assam and Tripura have a sizeable Bengali population. A large Bengali diaspora exists across the world. Bengali is the sixth-most spoken language in the world.
Bengal PresidencyThe Bengal Presidency, officially the Presidency of Fort William in Bengal and later Bengal Province, was a subdivision of British India. At the height of its territorial jurisdiction, it covered large parts of what is now South Asia and Southeast Asia. Bengal proper covered the ethno-linguistic region of Bengal (present-day Bangladesh and the Indian state of West Bengal). Calcutta, the city which grew around Fort William, was the capital of the Bengal Presidency.
Bengal SultanateThe Bengal Sultanate (Middle Bengali: শাহী বাঙ্গালা Shahī Baṅgala, Classical Persian: Saltanat-e-Bangālah) was a Sunni Muslim empire based in Bengal for much of the 14th, 15th and 16th centuries. It was the dominant power of the Ganges–Brahmaputra Delta, with a network of mint towns spread across the region. The Bengal Sultanate had a circle of vassal states in the subcontinent, including parts of Odisha in the southwest, Arakan in the southeast, and Tripura in the east.
North BengalNorth Bengal (উত্তরবঙ্গ/উত্তর বাংলা) is a term used for the north-western part of Bangladesh and northern part of West Bengal. The Bangladesh part denotes the Rajshahi Division and Rangpur Division. Generally, it is the area lying west of Jamuna River and north of Padma River and includes the Barind Tract. The West Bengal part denotes Jalpaiguri Division (Alipurduar, Cooch Behar, Darjeeling, Jalpaiguri, and Kalimpong) and the Malda division (Uttar Dinajpur, Dakshin Dinajpur, and Malda) together.
West BengalWest Bengal (bɛnˈɡɔːl, Bengali: Poshchim Bongo, ˈpoʃtʃim ˈbɔŋɡo, abbr. WB) is a state in the eastern portion of India. It is situated along the Bay of Bengal, along with a population of over 91 million inhabitants within an area of as of 2011. The population estimate as of 2023 is 102,552,787. West Bengal is the fourth-most populous and thirteenth-largest state by area in India, as well as the eighth-most populous country subdivision of the world.
History of BengalThe history of Bengal is intertwined with the history of the broader Indian subcontinent and the surrounding regions of South Asia and Southeast Asia. It includes modern-day Bangladesh and the Indian states of West Bengal, Tripura and Assam's Karimganj district, located in the eastern part of the Indian subcontinent, at the apex of the Bay of Bengal and dominated by the fertile Ganges delta. The region was known to the ancient Greeks and Romans as Gangaridai, a powerful kingdom whose war elephant forces led the withdrawal of Alexander the Great from India.
CholeraCholera ('kɒlərə) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish.
ClimateClimate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them.
Likelihood functionIn statistical inference, the likelihood function quantifies the plausibility of parameter values characterizing a statistical model in light of observed data. Its most typical usage is to compare possible parameter values (under a fixed set of observations and a particular model), where higher values of likelihood are preferred because they correspond to more probable parameter values.
Water resourcesWater resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on Earth is salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water.
