Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étampes
Étampes () is a commune in the metropolitan area of Paris, France. It is located south-southwest from the center of Paris (as the crow flies). Étampes is a sub-prefecture of the Essonne department. Étampes, together with the neighboring communes of Morigny-Champigny and Brières-les-Scellés, form an urban area of 30,881 inhabitants (2018). This urban area is a "satellite city" of Paris. History Étampes () existed at the beginning of the 7th century and in the early Middle Ages belonged to the crown domain. During the Middle Ages it was the scene of several councils, the most notable of which took place in 1130 and resulted in the recognition of Innocent II as the legitimate pope. In 1652, during the war of the Fronde it suffered severely at the hands of the royal troops under Turenne. Geography Étampes lies on the river Chalouette, a tributary of the Juine, which borders the eastern outskirts of the serene town. Inhabitants of Étampes are known as ''Étampois' ...

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 ...

Alexandria
Alexandria ( or ; ar, ٱلْإِسْكَنْدَرِيَّةُ ; grc-gre, Αλεξάνδρεια, Alexándria) is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria, which ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about along the northern coast of Egypt, and is the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Baptiste Joseph Fourier
Jean-Baptiste Joseph Fourier (; ; 21 March 1768 – 16 May 1830) was a French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's law of conduction are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect. Biography Fourier was born at Auxerre (now in the Yonne département of France), the son of a tailor. He was orphaned at the age of nine. Fourier was recommended to the Bishop of Auxerre and, through this introduction, he was educated by the Benedictine Order of the Convent of St. Mark. The commissions in the scientific corps of the army were reserved for those of good birth, and being thus ineligible, he accepted a military lectureship on mathematics. He took a prominent part in his own d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Claude Louis Berthollet
Claude Louis Berthollet (, 9 December 1748 – 6 November 1822) was a Savoyard-French chemist who became vice president of the French Senate in 1804. He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature. On a practical basis, Berthollet was the first to demonstrate the bleaching action of chlorine gas, and was first to develop a solution of sodium hypochlorite as a modern bleaching agent. Biography Claude Louis Berthollet was born in Talloires, near Annecy, then part of the Duchy of Savoy, in 1749. He started his studies at Chambéry and then in Turin where he graduated in medicine. Berthollet's great new developments in works regarding chemistry made him, in a short period of time, an active participant of the Academy of Science in 1780. Berthollet, along with Antoine Lavoisier and others, devised a chemical nomenclature, or a system of name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominique-Vivant Denon
Dominique Vivant, Baron Denon (4 January 1747 – 27 April 1825) was a French artist, writer, diplomat, author, and archaeologist. Denon was a diplomat for France under Louis XV and Louis XVI. He was appointed as the first Director of the Louvre museum by Napoleon after the Egyptian campaign of 1798–1801, and is commemorated in the Denon Wing of the modern museum and in the Dominique-Vivant Denon Research Center. His two-volume ''Voyage dans la basse et la haute Egypte'' ("Journey in Lower and Upper Egypt"), 1802, was foundational for modern Egyptology. Birth and name Vivant Denon was born at Chalon-sur-Saône to a family called "de Non", of the "petite noblesse" or gentry, and until the French Revolution signed himself as "le chevalier de Non". Like many of the nobility, he revised his surname at the Revolution to lose the "nobiliary particle" "de". He seems to have consistently avoided using his baptised first name "Dominique", preferring his middle name "Vivant", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institut D'Égypte
The Institut d'Égypte or Egyptian Scientific Institute is a learned society in Cairo specializing in Egyptology. It was established in 1798 by Napoleon Bonaparte to carry out research during his Egyptian campaign and is the oldest scientific institute in Egypt. The building in which it was housed was burnt down, with the loss of many documents, during the Arab Spring unrest of 2011. It reopened in December 2012. Early work The Institut d'Égypte was founded on 22 August 1798 by Napoleon Bonaparte for the Institut de France, their mission was "progress and the propagation of the Enlightenment in Egypt." The institute was organised into sections that cover all the topics of interest and study in mathematics, physics, political economy, literature and arts by the Commission des Sciences et des Arts. The society first met on 24 August 1798, with Gaspard Monge as president, Bonaparte himself as vice-president and Joseph Fourier and Costaz as secretaries. It had 48 scholars and as ...

Zoology
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire ...
