Ramchundra
Ramchundra (Ramachandra Lal) (Devanagari,रामचन्द्र लाल) (1821–1880) was a British Indian mathematician. His book, ''Treatise on Problems of Maxima and Minima'', was promoted by the prominent mathematician Augustus De Morgan. Writing in his preface to the treatise, De Morgan states that Ramchundra was born in 1821 in Panipat to Sunder Lal, a Kayasth of Delhi. He came to De Morgan’s attention when, in 1850, a friend sent him Ramchundra’s work on maxima and minima. The 29-year-old self-taught mathematician had published the book at his own expense in Calcutta in that year. De Morgan was so impressed that he arranged for the book to be republished in London under his own supervision, and in general undertook to bring Ramchundra's work to the notice of the broader European scientific community. Quoting De Morgan, from the preface of the treatise: Charles Muses, in an article in the ''Mathematical Intelligencer'' (1998) called Ramchundra "De Morgan's R ...

Panipat
Panipat () is a historic city in Haryana, India. It is 95 km north of Delhi and 169 km south of Chandigarh on List of National Highways in India, NH-1. The three major battles fought in First Battle of Panipat, 1526, Second Battle of Panipat, 1556 and Third Battle of Panipat, 1761 took place near the city. The city is famous in India as the "City of Weavers" and "Textile City". It is also known as the "cast-off capital" due to being "the global centre for recycling textiles".

Kayasth
Kayastha (also referred to as Kayasth) denotes a cluster of disparate Indian communities broadly categorised by the regions of the Indian subcontinent in which they were traditionally locatedthe Chitraguptavanshi Kayasthas of North India, the Chandraseniya Kayastha Prabhus of Maharashtra, the Bengali Kayasthas of Bengal and Karanas of Odisha. All of them were traditionally considered "writing castes", who had historically served the ruling powers as administrators, ministers and record-keepers. The earliest known reference to the term ''Kayastha'' dates back to the Kushan Empire, when it evolved into a common name for a writer or scribe. In the Sanskrit literature and inscriptions, it was used to denote the holders of a particular category of offices in the government service. In this context, the term possibly derived from ('principal, capital, treasury') and - ('to stay') and perhaps originally stood for an officer of the royal treasury, or revenue department.

Maxima And Minima
In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the ''local'' or ''relative'' extrema), or on the entire domain (the ''global'' or ''absolute'' extrema). Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions. As defined in set theory, the maximum and minimum of a set are the greatest and least elements in the set, respectively. Unbounded infinite sets, such as the set of real numbers, have no minimum or maximum. Definition A real-valued function ''f'' defined on a domain ''X'' has a global (or absolute) maximum point at ''x''∗, if for all ''x'' in ''X''. Similarly, the function has a global (or absolute) minimum point at ''x''∗, if for all ''x'' in ''X''. The value of the function at a m ...

Charles Muses
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depr ...

Mathematical Intelligencer
''The Mathematical Intelligencer'' is a mathematical journal published by Springer Verlag that aims at a conversational and scholarly tone, rather than the technical and specialist tone more common among academic journals. Volumes are released quarterly with a subset of open access articles. Springer also cross-publishes some of the articles in ''Scientific American''. Karen Parshall and Sergei Tabachnikov are currently the co-editors-in-chief. History The journal was started informally in 1971 by Walter Kaufman-Buehler, Alice Peters and Klaus Peters. "Intelligencer" was chosen by Kaufman-Buehler as a word that would appear slightly old-fashioned. An exploration of mathematically themed stamps, written by Robin Wilson, became one of its earliest columns. In 1978, the founders appointed Bruce Chandler and Harold "Ed" Edwards Jr. to serve jointly in the role of editor-in-chief. Prior to 1978, articles of the ''Intelligencer'' were not contained in regular volumes and were sent out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century Indian Mathematicians
The 19th (nineteenth) century began on 1 January 1801 (Roman numerals, MDCCCI), and ended on 31 December 1900 (Roman numerals, MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolitionism, abolished in much of Europe and the Americas. The Industrial Revolution, First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost ...
