French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, 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 nationale de France, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century French Photographers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The 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 Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maxime Du Camp
Maxime Du Camp (8 February 1822 – 9 February 1894) was a French writer and photographer. Biography Born in Paris, Du Camp was the son of a successful surgeon. After finishing college, he indulged in his strong desire for travel, thanks to his father's assets. Du Camp traveled in Europe and the East between 1844 and 1845, and again between 1849 and 1851 in company with Gustave Flaubert. After his return, Du Camp wrote about his traveling experiences. Flaubert also wrote about his experiences with Maxime. In 1851, Du Camp became a founder of the ''Revue de Paris'' (suppressed in 1858), in which his friend Flaubert's Madame Bovary was first published in serialised form in 1856, as well as a frequent contributor to the '' Revue des deux mondes''. In 1853, he became an officer of the Legion of Honour. Serving as a volunteer with Garibaldi in his 1860 conquest of the Kingdom of the Two Sicilies, Du Camp recounted his experiences in ''Expédition des deux Siciles'' (1861). In 1 ...

Hippolyte Fockedey
In Classical Greek mythology, Hippolyta, or Hippolyte (; grc-gre, Ἱππολύτη ''Hippolytē'') was a daughter of Ares and Otrera, queen of the Amazons, and a sister of Antiope and Melanippe. She wore her father Ares' ''zoster'', the Greek word found in the Iliad and elsewhere meaning "war belt." Some traditional English translations have preferred the more feminine-sounding " girdle." Hippolyta figures prominently in the myths of both Heracles and Theseus. The myths about her are varied enough that they may therefore be about several different women. The name ''Hippolyta'' comes from Greek roots meaning "horse" and "let loose." Legends Ninth Labor of Heracles In the myth of Heracles, Hippolyta's belt (ζωστὴρ Ἱππολύτης) was the object of his ninth labour. He was sent to retrieve it for Admete, the daughter of King Eurystheus.Hyginus, ''Fabulae'', 30 Most versions of the myth indicate that Hippolyta was so impressed with Heracles that she gav ...

Carte De Visite
The ''carte de visite'' (, visiting card), abbreviated CdV, was a type of small photograph which was patented in Paris by photographer André Adolphe Eugène Disdéri in 1854, although first used by Louis Dodero. Each photograph was the size of a visiting card, and such photograph cards were commonly traded among friends and visitors in the 1860s. Albums for the collection and display of cards became a common fixture in Victorian parlors. The immense popularity of these card photographs led to the publication and collection of photographs of prominent persons. History and format The ''carte de visite'' was usually made of an albumen print, which was a thin paper photograph mounted on a thicker paper card. The size of a ''carte de visite'' is × mounted on a card sized × . In 1854, Disdéri had also patented a method of taking eight separate negatives on a single plate, which reduced production costs. The ''carte de visite'' was slow to gain widespread use until 1859, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Nitrate
Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar caustic'' because silver was called ''luna'' by ancient alchemists who associated silver with the moon. In solid silver nitrate, the silver ions are three- coordinated in a trigonal planar arrangement. Synthesis and structure Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. The stoichiometry of the reaction depends upon the concentration of nitric acid used. :3 Ag + 4 HNO3 (cold and diluted) → 3 AgNO3 + 2 H2O + NO :Ag + 2 HNO3 (hot and concentrated) → AgNO3 + H2O + NO2 The structure of silver nitrate has been examined by X-ray crystallography sever ...

French First Republic
In the history of France, the First Republic (french: Première République), sometimes referred to in historiography as Revolutionary France, and officially the French Republic (french: République française), was founded on 21 September 1792 during the French Revolution. The First Republic lasted until the declaration of the First Empire on 18 May 1804 under Napoléon Bonaparte, although the form of the government changed several times. This period was characterized by the fall of the monarchy, the establishment of the National Convention and the Reign of Terror, the Thermidorian Reaction and the founding of the Directory, and, finally, the creation Creation may refer to: Religion *''Creatio ex nihilo'', the concept that matter was created by God out of nothing * Creation myth, a religious story of the origin of the world and how people first came to inhabit it * Creationism, the belief tha ... of the French Consulate, Consulate and Napoleon's rise to power.

Potassium Iodide
Potassium iodide is a chemical compound, medication, and dietary supplement. It is a medication used for treating hyperthyroidism, in radiation emergencies, and for protecting the thyroid gland when certain types of radiopharmaceuticals are used. In the third world it is also used for treating skin sporotrichosis and phycomycosis. It is a supplement used by people with low dietary intake of iodine. It is administered orally. Common side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands. Other side effects include allergic reactions, headache, goitre, and depression. While use during pregnancy may harm the baby, its use is still recommended in radiation emergencies. Potassium iodide has the chemical formula K I. Commercially it is made by mixing potassium hydroxide with iodine. Potassium iodide has been used medically since at least 1820. It is on the World Health Organization's List of Essential Medicines. Potassium iodide is av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calotype
Calotype or talbotype is an early photographic process introduced in 1841 by William Henry Fox Talbot, using paper coated with silver iodide. Paper texture effects in calotype photography limit the ability of this early process to record low contrast details and textures. The term ''calotype'' comes from the Ancient Greek (), "beautiful", and (), "impression". The process Talbot made his first successful camera photographs in 1835 using paper sensitised with silver chloride, which darkened in proportion to its exposure to light. This early "photogenic drawing" process was a ''printing-out'' process, i.e., the paper had to be exposed in the camera until the image was fully visible. A very long exposure—typically an hour or more—was required to produce an acceptable negative. In late 1840, Talbot worked out a very different ''developing-out'' process (a concept pioneered by the daguerreotype process introduced in 1839), in which only an extremely faint or completely invi ...
