Kadambini Ganguly
Kadambini Bose Ganguly (18 July 1861 – 3 October 1923) was one of the first Indian female doctors who practised with a degree in modern medicine. She was the first Indian woman to practice medicine in India. Ganguly was the first woman to gain admission to Calcutta Medical College in 1884, subsequently trained in Scotland, and established a successful medical practice in India. She was the first woman speaker in the Indian National Congress. Early life Ganguly(Basu) was born in Bengali Kayastha family as Kadambini Basu who was the daughter of Brahmo reformer Braja Kishore Basu. She was born on 18 July 1861 at Bhagalpur, Bengal Presidency (modern day Bihar) in British India, raised in Barisal. The family was from Chandsi, in Barisal which is now in Bangladesh. Her father was headmaster of Bhagalpur School. He and Abhay Charan Mallick started the movement for women's emancipation at Bhagalpur, establishing the women's organisation Bhagalpur Mahila Samiti in 1863, the first i ...

Woman's Medical College Of Pennsylvania
The Woman's Medical College of Pennsylvania (WMCP) was founded in 1850, and was the second medical institution in the world established to train women in medicine to earn the M.D. degree. The New England Female Medical College had been established two years earlier in 1848. Originally called the Female Medical College of Pennsylvania, the college changed its name in 1867 to Woman's Medical College of Pennsylvania. The associated Woman's Hospital of Philadelphia was founded in 1861. Upon deciding to admit men in 1970, the college was renamed as the Medical College of Pennsylvania (MCP). In 1930, the college opened its new campus in East Falls, which combined teaching and the clinical care of a hospital in one overall facility. It was the first purpose-built hospital in the nation. In 1993, the college and hospital merged with Hahnemann Medical School. In 2003, the two colleges were absorbed by the Drexel University College of Medicine. Founding R.C. Smedley's ''History of the Und ...

Anandi Gopal Joshi
Dr. Anandibai Gopalrao Joshi (31 March 1865 – 26 February 1887) was the first Indian female doctor of western medicine. She was the first woman from the erstwhile Bombay presidency of India to study and graduate with a two-year degree in western medicine in the United States. She was also referred to as ''Anandibai Joshi'' and ''Anandi Gopal Joshi'' (where ''Gopal'' came from ''Gopalrao'', her husband's first name). Early life Originally named Yamuna, Joshi was born, raised in a Marathi Chitpavan Brahmin family As was the practice at that time and due to pressure from her mother, she was married at the age of nine to Gopalrao Joshi, a widower almost twenty years her senior. After marriage, Yamuna's husband renamed her 'Anandi'. Gopalrao Joshi worked as a postal clerk in Kalyan. Later, he was transferred to Alibag, and then, finally, to Kolhapoor (Kolhapur). He was a progressive thinker, and, unusually for that time, supported education for women. She was also a relative of Pa ...

Indian People
Indians or Indian people are the Indian nationality law, citizens and nationals of India. In 2022, the population of India stood at over 1.4 billion people, making it the world's List of countries and dependencies by population, second-most populous country, containing 17.7 percent of the global population. In addition to the Indian population, the Non-resident Indian and Overseas Citizen of India, Indian overseas diaspora also boasts large numbers, particularly in the Arab states of the Persian Gulf and the Western world. While the demonym "Indian" applies to people originating from the present-day Republic of India, it was also formerly used as the identifying term for people originating from Pakistan and Bangladesh during British Raj, British colonial era until 1947. Particularly in North America, the terms "Asian Indian" and "East Indian" are sometimes used to differentiate Indians from the indigenous peoples of the Americas; although the Native American name controversy, ...

Weak Ordering
In mathematics, especially order theory, a weak ordering is a mathematical formalization of the intuitive notion of a ranking of a set, some of whose members may be tied with each other. Weak orders are a generalization of totally ordered sets (rankings without ties) and are in turn generalized by partially ordered sets and preorders.. There are several common ways of formalizing weak orderings, that are different from each other but cryptomorphic (interconvertable with no loss of information): they may be axiomatized as strict weak orderings (partially ordered sets in which incomparability is a transitive relation), as total preorders (transitive binary relations in which at least one of the two possible relations exists between every pair of elements), or as ordered partitions (partitions of the elements into disjoint subsets, together with a total order on the subsets). In many cases another representation called a preferential arrangement based on a utility function is a ...

Ordered Bell Number
In number theory and enumerative combinatorics, the ordered Bell numbers or Fubini numbers count the number of weak orderings on a set of ''n'' elements (orderings of the elements into a sequence allowing ties, such as might arise as the outcome of a horse race).. Because of this application, de Koninck calls these numbers "horse numbers", but this name does not appear to be in widespread use. Starting from ''n'' = 0, these numbers are :1, 1, 3, 13, 75, 541, 4683, 47293, 545835, 7087261, 102247563, ... . The ordered Bell numbers may be computed via a summation formula involving binomial coefficients, or by using a recurrence relation. Along with the weak orderings, they count several other types of combinatorial objects that have a bijective correspondence to the weak orderings, such as the ordered multiplicative partitions of a squarefree number or the faces of all dimensions of a permutohedron (e.g. the sum of faces of all dimensions in the truncated octahedron is 1 + ...

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.
