Augusta, Maine
Augusta is the capital of the U.S. state of Maine and the county seat of Kennebec County. The city's population was 18,899 at the 2020 census, making it the tenth-most populous city in Maine, and third-least populous state capital in the United States after Montpelier, Vermont, and Pierre, South Dakota. Located on the Kennebec River at the head of tide, it is the principal city in the Augusta-Waterville Micropolitan Statistical Area and home to the University of Maine at Augusta. History The area was first explored by the English of the short-lived Popham Colony in September 1607. 21 years later, English settlers from the Plymouth Colony settled in the area in 1628 as part of a trading post on the Kennebec River. The settlement was known by its Native American name ''Cushnoc'' (or Coussinoc or Koussinoc), meaning "head of the tide." Fur trading was at first profitable, but because of Native uprisings and declining revenues, Plymouth Colony sold the Kennebec Patent in 1 ...

Thomas Tredgold
Thomas Tredgold (1788–1829) was an English engineer and author, known for his early work on railroad construction. His definition of civil engineering formed the basis of the charter of the Institution of Civil Engineers. Biography He was born at Brandon, County Durham, on 22 August 1788. After some elementary education at the village school, he was apprenticed at 14 to a cabinet-maker in Durham. He remained with him six years, studying also mathematics, architecture, and perspective. In 1808, after his apprenticeship had expired, he went to Scotland, where he worked for five years as a joiner and journeyman carpenter. Later Tredgold went to London, where he entered the office of his uncle William Atkinson the architect, with whom he lived for six years, and whom he served for longer. He read on architecture and engineering; and taught himself French. In 1823, the demands of his writing led Tredgold to resign his position in Atkinson's office. He died on 28 January 1829, ...

Louis Vicat
Louis Vicat (31 March 1786, Nevers – 10 April 1861, Grenoble) was a French engineer. He graduated from the École Polytechnique in 1804 and the École des Ponts et Chaussées in 1806. Vicat studied the setting of mortars and developed his own. The first building using it is the bridge at Souillac (Dordogne), erected in 1818. The material was popular but was superseded by Portland cement. He also invented the Vicat needle that is still in use for determining the setting time of concretes and cements. His son Joseph Vicat founded Vicat Cement, which is today a large international cement manufacturing company. He was a member of the French Academy of Sciences and his name is one of the 72 names inscribed on the Eiffel Tower. Vicat was elected a Foreign Honorary Member of the American Academy of Arts and Sciences The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Claude-Louis Navier
Claude-Louis Navier (born Claude Louis Marie Henri Navier; ; 10 February 1785 – 21 August 1836) was a French mechanical engineer, affiliated with the French government, and a physicist who specialized in continuum mechanics. The Navier–Stokes equations refer eponymously to him, with George Gabriel Stokes. Biography After the death of his father in 1793, Navier's mother left his education in the hands of his uncle Émiland Gauthey, an engineer with the Corps of Bridges and Roads ''(Corps des Ponts et Chaussées)''. In 1802, Navier enrolled at the École polytechnique, and in 1804 continued his studies at the École Nationale des Ponts et Chaussées, from which he graduated in 1806. He eventually succeeded his uncle as ''Inspecteur general'' at the Corps des Ponts et Chaussées. He directed the construction of bridges at Choisy, Asnières and Argenteuil in the Department of the Seine, and built a footbridge to the Île de la Cité in Paris. His 1824 design for the Pont ...

Émiland Gauthey
Émiland Marie Gauthey ( in Chalon-sur-Saône – in Paris) was a French mathematician, civil engineer and architect. As an engineer for the Estates of Burgundy (french: États de Bourgogne), he was the creator of a great deal of the region's civil infrastructure, such as the Canal du Centre between Digoin and Chalon-sur-Saône (1784–1793), bridges including those at Navilly (1782–1790) and Gueugnon (1784–1787), and buildings such as the ("Church of St Peter and St Paul") at Givry (1772 – 1791) and the theatre at Chalon-sur-Saône. Gauthey became Chief Engineer of the ''États de Bourgogne'' in 1782, on the death of his predecessor and close collaborator, Thomas Dumorey. After the French Revolution, he held several important posts in the ("High Commission for Bridges and ighays") in Paris. He was awarded the Légion d'honneur in 1804 on its creation by Napoleon Bonaparte. From 1805 until his death, he was the highest-ranked engineer in France. Biography Émil ...

Mechanics
Mechanics (from Ancient Greek: μηχανική, ''mēkhanikḗ'', "of machines") is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements, or changes of an object's position relative to its environment. Theoretical expositions of this branch of physics has its origins in Ancient Greece, for instance, in the writings of Aristotle and Archimedes (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, Huygens, and Newton laid the foundation for what is now known as classical mechanics. As a branch of classical physics, mechanics deals with bodies that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as the physical science that deals with the motion of and forces on bodies not in the quantum realm ...

Algebra
Algebra () is one of the broad areas of mathematics. Roughly speaking, algebra is the study of mathematical symbols and the rules for manipulating these symbols in formulas; it is a unifying thread of almost all of mathematics. Elementary algebra deals with the manipulation of variables (commonly represented by Roman letters) as if they were numbers and is therefore essential in all applications of mathematics. Abstract algebra is the name given, mostly in education, to the study of algebraic structures such as groups, rings, and fields (the term is no more in common use outside educational context). Linear algebra, which deals with linear equations and linear mappings, is used for modern presentations of geometry, and has many practical applications (in weather forecasting, for example). There are many areas of mathematics that belong to algebra, some having "algebra" in their name, such as commutative algebra, and some not, such as Galois theory. The word ''algebra'' is ...

Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geometries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmetic
Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers— addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, but t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Management
Management (or managing) is the administration of an organization, whether it is a business, a nonprofit organization, or a government body. It is the art and science of managing resources of the business. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. "Run the business" and "Change the business" are two concepts that are used in management to differentiate between the continued delivery of goods or services and adapting of goods or services to meet the changing needs of customers - see trend. The term "management" may also refer to those people who manage an organization—managers. Some people study management at colleges or universities; major degrees in management includes the Bachelor of Commerce (B.Com.), Bachelor of Business Adminis ...
