Pavillon De Breteuil
The Pavillon de Breteuil is the headquarters of the International Bureau of Weights and Measures (BIPM). The building lies in the southeastern section of the Parc de Saint-Cloud in Saint-Cloud, France, to the west of Paris. It is listed in France as an Monument historique, historic monument. History Built overlooking the River Seine by Thomas Gobert (architect), Thomas Gobert in the parkland surrounding the Château de Saint-Cloud, the building was inaugurated by Louis XIV in 1672 and first known as the ''Trianon de Saint-Cloud''. The ''Trianon'' was renamed as the ''Pavillon du Mail'' in 1743 after being slightly modified. In 1785 the whole of the château estate (the ''Domaine de Saint-Cloud''), including the pavillon, was acquired by Marie Antoinette, the queen of Louis XVI of France, Louis XVI. For his part in arranging the acquisition of the pavillon, the queen granted Louis Auguste Le Tonnelier de Breteuil the use of the estate, and he made the pavillon his official residen ...

Louis XVI Of France
Louis XVI (''Louis-Auguste''; ; 23 August 175421 January 1793) was the last King of France before the fall of the monarchy during the French Revolution. He was referred to as ''Citizen Louis Capet'' during the four months just before he was executed by guillotine. He was the son of Louis, Dauphin of France, son and heir-apparent of King Louis XV, and Maria Josepha of Saxony. When his father died in 1765, he became the new Dauphin. Upon his grandfather's death on 10 May 1774, he became King of France and Navarre, reigning as such until 4 September 1791, when he received the title of King of the French, continuing to reign as such until the monarchy was abolished on 21 September 1792. The first part of his reign was marked by attempts to reform the French government in accordance with Enlightenment ideas. These included efforts to abolish serfdom, remove the '' taille'' (land tax) and the ''corvée'' (labour tax), and increase tolerance toward non-Catholics as well as abo ...

2019 Redefinition Of The SI Base Units
In 2019, four of the seven SI base units specified in the International System of Quantities were redefined in terms of natural physical constants, rather than human artifacts such as the standard kilogram. Effective 20 May 2019, the 144th anniversary of the Metre Convention, the kilogram, ampere, kelvin, and mole are now defined by setting exact numerical values, when expressed in SI units, for the Planck constant ('), the elementary electric charge ('), the Boltzmann constant (), and the Avogadro constant (), respectively. The second, metre, and candela had previously been redefined using physical constants. The four new definitions aimed to improve the SI without changing the value of any units, ensuring continuity with existing measurements. In November 2018, the 26th General Conference on Weights and Measures (CGPM) unanimously approved these changes, The conference ran from 13–16 November and the vote on the redefinition was scheduled for the last day.

Kilogram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum '' Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for ...

International Committee For Weights And Measures
The General Conference on Weights and Measures (GCWM; french: Conférence générale des poids et mesures, CGPM) is the supreme authority of the International Bureau of Weights and Measures (BIPM), the intergovernmental organization established in 1875 under the terms of the Metre Convention through which member states act together on matters related to measurement science and measurement standards. The CGPM is made up of delegates of the governments of the member states and observers from the Associates of the CGPM. Under its authority, the International Committee for Weights and Measures (ICWM; ) executes an exclusive direction and supervision of the BIPM. Initially the Metre Convention was only concerned with the kilogram and the metre, but in 1921 the scope of the treaty was extended to accommodate all physical measurements and hence all aspects of the metric system. In 1960 the 11th CGPM approved the International System of Units, usually known as "SI". The General Confer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metric System
The metric system is a system of measurement that succeeded the decimalised system based on the metre that had been introduced in France in the 1790s. The historical development of these systems culminated in the definition of the International System of Units (SI) in the mid-20th century, under the oversight of an international standards body. Adopting the metric system is known as ''metrication''. The historical evolution of metric systems has resulted in the recognition of several principles. Each of the fundamental dimensions of nature is expressed by a single base unit of measure. The definition of base units has increasingly been realised from natural principles, rather than by copies of physical artefacts. For quantities derived from the fundamental base units of the system, units derived from the base units are used—e.g., the square metre is the derived unit for area, a quantity derived from length. These derived units are coherent, which means that they inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napoleon
Napoleon Bonaparte ; it, Napoleone Bonaparte, ; co, Napulione Buonaparte. (born Napoleone Buonaparte; 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a French military commander and political leader who rose to prominence during the French Revolution and led successful campaigns during the Revolutionary Wars. He was the ''de facto'' leader of the French Republic as First Consul from 1799 to 1804, then Emperor of the French from 1804 until 1814 and again in 1815. Napoleon's political and cultural legacy endures to this day, as a highly celebrated and controversial leader. He initiated many liberal reforms that have persisted in society, and is considered one of the greatest military commanders in history. His wars and campaigns are studied by militaries all over the world. Between three and six million civilians and soldiers perished in what became known as the Napoleonic Wars. Napoleon was born on the island of Corsica, not long af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Revolution
The French Revolution ( ) was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in coup of 18 Brumaire, November 1799. Many of its ideas are considered fundamental principles of liberal democracy, while phrases like ''liberté, égalité, fraternité'' reappeared in other revolts, such as the 1917 Russian Revolution, and inspired campaigns for the abolitionism, abolition of slavery and universal suffrage. The values and institutions it created dominate French politics to this day. Its Causes of the French Revolution, causes are generally agreed to be a combination of social, political and economic factors, which the ''Ancien Régime'' proved unable to manage. In May 1789, widespread social distress led to the convocation of the Estates General of 1789, Estates General, which was converted into a National Assembly (French Revolution), National Assembly in June.

Louis Auguste Le Tonnelier De Breteuil
Louis Charles Auguste Le Tonnelier, Baron de Breteuil, Baron de Preuilly (7 March 1730 – 2 November 1807) was a French aristocrat, diplomat and statesman. He was the last chief minister of the Bourbon Monarchy, appointed by King Louis XVI only one hundred hours before the storming of the Bastille. Soldier and ambassador Breteuil was born in 1730 at the chateau of Azay-le-Ferron (Indre) into a well-connected aristocratic family: one of his relations was confessor to the king's cousin and another was the famed mathematician and linguist Émilie, marquise du Châtelet-Laumont. He received an excellent education in Paris and later joined the army, where he fought in the Seven Years' War. In 1758 he left the army and joined the French Foreign Ministry. He was quickly appointed French ambassador to the elector of Cologne, where he proved to have valuable diplomatic skills. Two years later in 1760 he was sent to St Petersburg as the French ambassador to Imperial Russia, wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Antoinette
Marie Antoinette Josèphe Jeanne (; ; née Maria Antonia Josepha Johanna; 2 November 1755 – 16 October 1793) was the last queen of France before the French Revolution. She was born an archduchess of Austria, and was the penultimate child and youngest daughter of Empress Maria Theresa and Emperor Francis I. She became dauphine of France in May 1770 at age 14 upon her marriage to Louis-Auguste, heir apparent to the French throne. On 10 May 1774, her husband ascended the throne as Louis XVI and she became queen. Marie Antoinette's position at court improved when, after eight years of marriage, she started having children. She became increasingly unpopular among the people, however, with the French '' libelles'' accusing her of being profligate, promiscuous, allegedly having illegitimate children, and harboring sympathies for France's perceived enemies—particularly her native Austria. The false accusations of the Affair of the Diamond Necklace damaged her reputation furthe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parc De Saint-Cloud
The Parc de Saint-Cloud, officially the ''Domaine National de Saint-Cloud'', is a ''domaine national'' (national estate), located mostly within Saint-Cloud, in the Hauts-de-Seine department, near Paris, France. The park, which covers , was a nature reserve until 1923. It is considered one of the most beautiful gardens in Europe, and in 2005 the park was awarded '' Notable Garden'' status. On 9 November 1994 the park was classified as a Historic Monument. In 1999 a winter storm heavily damaged the park's forests. The park is operated as a ''domaine national'' under the French Ministry of Culture. History The park is located on the site of the Château de Saint-Cloud, a residence of royal and imperial families from the 16th century. After Napoleon III declared war on the Prussians, the site was occupied by a Prussian force which used the high outcropping to shell Paris. Counter-fire from the French caused the building to burn on 13 October 1870. The structure was completely razed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
