Henri Pitot
Henri Pitot (; May 3, 1695 – December 27, 1771) was a French hydraulic engineer and the inventor of the pitot tube. In a pitot tube, the height of the fluid column is proportional to the square of the velocity of the fluid at the depth of the inlet to the pitot tube. This relationship was discovered by Henri Pitot in 1732, when he was assigned the task of measuring the flow in the river Seine. He rose to fame with the design of the Aqueduc de Saint-Clément near Montpellier (the construction lasted thirteen years), and the extension of Pont du Gard in Nîmes. In 1724, he became a member of the French Academy of Sciences, and in 1740 a fellow of the Royal Society. The Pitot theorem of plane geometry is named after him.

Nîmes
Nîmes ( , ; oc, Nimes ; Latin: ''Nemausus'') is the prefecture of the Gard department in the Occitanie region of Southern France. Located between the Mediterranean Sea and Cévennes, the commune of Nîmes has an estimated population of 148,561 (2019). Dubbed the most Roman city outside Italy, Nîmes has a rich history dating back to the Roman Empire when the city had a population of 50,000–60,000 and was the regional capital. Several famous monuments are in Nîmes, such as the Arena of Nîmes and the Maison Carrée. Because of this, Nîmes is often referred to as the "French Rome". Origins Nimes is situated where the alluvial plain of the Vistrenque River abuts the hills of Mont Duplan to the northeast, Montaury to the southwest, and to the west Mt. Cavalier and the knoll of Canteduc. Its name appears in inscriptions in Gaulish as ''dede matrebo Namausikabo'' ("he has given to the mothers of Nîmes") and "''toutios Namausatis''" ("citizen of Nîmes"). Nemausus w ...

Hydraulic Engineers
Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water.Prasuhn, Alan L. ''Fundamentals of Hydraulic Engineering''. Holt, Rinehart, and Winston: New York, 1987. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour ...

Fluid Dynamicists
In physics, a fluid is a liquid, gas, or other material that continuously deforms (''flows'') under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them. Although the term ''fluid'' generally includes both the liquid and gas phases, its definition varies among branches of science. Definitions of ''solid'' vary as well, and depending on field, some substances can be both fluid and solid. Viscoelastic fluids like Silly Putty appear to behave similar to a solid when a sudden force is applied. Substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment) as well. In particle physics, the concept is extended to include fluidic matters other than liquids or gases. A fluid in medicine or biology refers any liquid constituent of the body (body fluid), whereas "liquid" is not used in this sense. Sometimes liquids given for fl ...

Carcassonne
Carcassonne (, also , , ; ; la, Carcaso) is a French fortified city in the department of Aude, in the region of Occitanie. It is the prefecture of the department. Inhabited since the Neolithic, Carcassonne is located in the plain of the Aude between historic trade routes, linking the Atlantic to the Mediterranean Sea and the Massif Central to the Pyrénées. Its strategic importance was quickly recognized by the Romans, who occupied its hilltop until the demise of the Western Roman Empire. In the fifth century, it was taken over by the Visigoths, who founded the city. Within three centuries, it briefly came under Islamic rule. Its strategic location led successive rulers to expand its fortifications until the Treaty of the Pyrenees in 1659. Its citadel, known as the Cité de Carcassonne, is a medieval fortress dating back to the Gallo-Roman period and restored by the theorist and architect Eugène Viollet-le-Duc in 1853. It was added to the UNESCO list of World Heri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its Brit ...

Pont Du Gard
The Pont du Gard is an ancient Roman aqueduct bridge built in the first century AD to carry water over to the Roman colony of ''Nemausus'' ( Nîmes). It crosses the river Gardon near the town of Vers-Pont-du-Gard in southern France. The Pont du Gard is the tallest of all Roman aqueduct bridges, as well as one of the best preserved. It was added to UNESCO's list of World Heritage sites in 1985 because of its exceptional preservation, historical importance, and architectural ingenuity. Description The bridge has three tiers of arches made from Shelly limestone and stands high. The aqueduct formerly carried an estimated of water a day over to the fountains, baths and homes of the citizens of Nîmes. The structure's precise construction allowed an average grade of in . It may have been in use as late as the 6th century, with some parts used for significantly longer, but a lack of maintenance after the 4th century led to clogging by mineral deposits and debris that eventual ...
