Entomologist
Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. In the past, the term ''insect'' was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British English insectology implies the study of the relationships between insects and humans. Over 1.3million insect species have been described by entomology. History Entomology is rooted in nearly all human cultures from prehistoric times, primarily in the context of agriculture (especially biological control and beekeeping). The natural Roman philosopher Pliny the Elder (23–79 CE) wrote a book on the kinds of insects, while the scientist of Kufa, ...

American Journal Of Mathematics
The ''American Journal of Mathematics'' is a bimonthly mathematics journal published by the Johns Hopkins University Press. History The ''American Journal of Mathematics'' is the oldest continuously published mathematical journal in the United States, established in 1878 at the Johns Hopkins University by James Joseph Sylvester, an English-born mathematician who also served as the journal's editor-in-chief from its inception through early 1884. Initially W. E. Story was associate editor in charge; he was replaced by Thomas Craig (mathematician), Thomas Craig in 1880. For volume 7 Simon Newcomb became chief editor with Craig managing until 1894. Then with volume 16 it was "Edited by Thomas Craig with the Co-operation of Simon Newcomb" until 1898. Other notable mathematicians who have served as editors or editorial associates of the journal include Frank Morley, Oscar Zariski, Lars Ahlfors, Hermann Weyl, Wei-Liang Chow, S. S. Chern, André Weil, Harish-Chandra, Jean Dieudonné, Hen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simon Newcomb
Simon Newcomb (March 12, 1835 – July 11, 1909) was a Canadians, Canadian–Americans, American astronomer, applied mathematician, and autodidactic polymath. He served as Professor of Mathematics in the United States Navy and at Johns Hopkins University. Born in Nova Scotia, at the age of 19 Newcomb left an apprenticeship to join his father in Massachusetts, where the latter was teaching. Though Newcomb had little conventional schooling, he completed a B.S. at Harvard in 1858. He later made important contributions to timekeeping, as well as to other fields in applied mathematics, such as economics and statistics. Fluent in several languages, he also wrote and published several popular science books and a science fiction novel. Biography Early life Simon Newcomb was born in the town of Wallace, Nova Scotia, Wallace, Nova Scotia. His parents were John Burton Newcomb and his wife Emily Prince. His father was an itinerant school teacher, and frequently moved in order to teach in d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Archaeology
Industrial archaeology (IA) is the systematic study of material evidence associated with the Industry (manufacturing), industrial past. This evidence, collectively referred to as industrial heritage, includes buildings, machinery, artifacts, sites, infrastructure, documents and other items associated with the production, manufacture, extraction, transport or construction of a product or range of products. The field of industrial archaeology incorporates a range of disciplines including archaeology, architecture, construction, engineering, historic preservation, museology, technology, urban planning and other specialties, in order to piece together the history of past industrial activities. The scientific interpretation of material evidence is often necessary, as the written record of many industrial techniques is often incomplete or nonexistent. Industrial archaeology includes both the examination of standing structures and sites that must be studied by an Excavation (archaeology ...

British India
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance in South Asia. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods: *Between 1612 and 1757, the East India Company set up "factories" (trading posts) in several locations, mostly in coastal India, with the consent of the Mughal emperors, Maratha Empire or local rulers. Its rivals were the merchant trading companies of Portugal, Denmark, the Netherlands, and France. By the mid-18th century three ''Presidency towns'': Madras, Bombay and Calcutta, had grown in size. *During the period of Company rule in India, 1757–1858, the Company gradually acquired sovereignty over large parts of India, now called "Presidencies". However, it also increasingly came under British government oversight, in effect sharing sovereig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bakhshali
Bakhshali () is a village and union council in Mardan District, Khyber-Pakhtunkhwa, Pakistan. It is located at 34°17'0N 72°9'0E and has an altitude of 307 metres (1010 feet). History The village is notable for being the location of what is now known as the Bakhshali manuscript. This is an ancient mathematical work written on birch bark and is the oldest surviving document in South Asia of Indian mathematics. It was discovered in 1881 during British rule The British Raj ( ; from Hindustani , 'reign', 'rule' or 'government') was the colonial rule of the British Crown on the Indian subcontinent, * * lasting from 1858 to 1947. * * It is also called Crown rule in India, * * * * or dire ... by the tenant of a local police inspector.

0 (number)
0 (zero) is a number representing an empty quantity. Adding (or subtracting) 0 to any number leaves that number unchanged; in mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 results in 0, and consequently division by zero has no meaning in arithmetic. As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, "205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya. Common names for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch Bark Manuscript
Birch bark manuscripts are documents written on pieces of the outer layer of birch bark, which was commonly used for writing before the mass production of paper. Evidence of birch bark for writing goes back many centuries and appears in various cultures. The oldest such manuscripts are the numerous Gandhāran Buddhist texts from approximately the 1st century CE, from what is now Afghanistan. They contain among the earliest known versions of significant Buddhist scriptures, including a ''Dhammapada'', discourses of Buddha that include the '' Rhinoceros Sutra'', Avadanas and Abhidharma texts. Sanskrit birch bark manuscripts written with Brahmi script have been dated to the first few centuries CE. Several early Sanskrit writers, such as Kālidāsa (), Sushruta (), and Varāhamihira (6th century CE) mention its use for manuscripts. The bark of '' Betula utilis'' (Himalayan Birch) is still used today in India and Nepal for writing sacred mantras. Russian texts discovered in Veliky Nov ...
