Jacques-Barthélemy Micheli Du Crest
Jacques-Barthélemy Micheli du Crest (September 28, 1690 – March 29, 1766) was a military engineer, physicist and cartographer, born in Geneva and so a citizen of the then Republic of Geneva, now in Switzerland. Born into the aristocracy, he eventually fled to France as an enemy of Geneva and eventually spent his later years in Aarburg Castle as a political prisoner. During his time there, he mapped the Alps accurately using rudimentary tools. One of his other major accomplishments whilst in exile was to create a thermometer and a temperature scale, which was commonly used in Switzerland and around Europe until it became obsolete in the 19th century. Life before exile Du Crest was born into the aristocracy, and during a period in the military he became a Captain and military engineer by the age of 23. In 1721, after leaving the army, he took up his place as a member of the Genevan parliament, as was his family's right, specialising in security. During his time in the parliame ...

Proof (alcohol)
Alcohol proof (usually termed simply "proof" in relation to a beverage) is a measure of the content of ethanol (alcohol) in an alcoholic beverage. The term was originally used in England and was equal to about 1.8 times the percentage of alcohol by volume (ABV). The UK now uses ABV instead of proof. In the United States, alcohol proof is defined as twice the percentage of ABV. The definition of proof in terms of ABV varies from country to country. The measurement of alcohol content and the statement of content on bottles of alcoholic beverages is regulated by law in many countries. In 1972, Canada phased out the use of "proof"; in 1973, the European Union followed suit; and the UK, where the concept originated, started using ABV instead in 1980. The US code mandates the use of ABV, but permits proof to be used also. The degree symbol (°) is sometimes used to indicate alcohol proof. History The term ''proof'' dates back to 16th century England, when spirits were taxed at di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
18th-century Physicists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.
