Jacques-Barthélemy Micheli Du Crest
Jacques-Barthélemy Micheli du Crest (Geneva, 28 September 1690 – Zofingen, 29 March 1766) was a military engineer, physicist and cartographer from the Republic of Geneva, now in Switzerland. Born into the aristocracy, he eventually fled to France as an enemy of Geneva and 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. Early life and career Du Crest was born in Geneva to Jacques Micheli du Crest, a captain in the mercenary troops of France, and Elisabeth Calandrini. He graduated from the Collège de Genève in 1705. Du Crest entered French service in 1709 and fought in the War of the Spanish Succession, reaching the rank of captain in 1712. He became a military engineer by th ...

Samuel Henzi
Samuel Henzi (19 April 1701 in Bümpliz of Bern – executed 17 July 1749 in Bern) was a Swiss writer, politician and revolutionary. He is chiefly known for his role in the "Henzi conspiracy" of June 1749, which aimed to overthrow the patrician government of Bern. Life Samuel Henzi was born the son of the pastor Johannes Henzi (1667-1740) and Maria Katharina Herzog. In his position as a copyist and bookkeeper at the Bern salt chamber, he was self-taught and possibly taught the patrician daughter Julie Bondeli as a private tutor. In the hope of a career and fortune, he bought himself a captain's position in the service of the Duke of Modena and Reggio, but failed miserably. In 1744, Samuel Henzi, who had signed a memorial for the restoration of Bern's old constitution, was expelled by resolution of the country's Great Council. In Neuchâtel he was editor of the ''Mercure Suisse'' and a contributor to the ''Journal hélvetique''. Henzi wrote several French poems, some under th ...

Military Engineers
Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes CBRN defense and other engineering disciplines such as mechanical and electrical engineering techniques. According to NATO, "military engineering is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment. Military engineering incorporates support to maneuver and to the force as a whole, including military engineering functions such as engineer support to force protection, counter improvised explosive devices, environmental protection, engineer intelligence and military search. Military engineering does not encompass the activities un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
18th-century Cartographers
The 18th century lasted from 1 January 1701 (represented by the Roman numerals MDCCI) to 31 December 1800 (MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the Atlantic Revolutions. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures. The Industrial Revolution began mid-century, leading to radical changes in human society and the environment. The European colonization of the Americas and other parts of the world intensified and associated mass migrations of people grew in size as part of the Age of Sail. During the century, slave trading expanded across the shores of the Atlantic Ocean, while declining in Russia and China. 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 Revolut ...

Telescope
A telescope is a device used to observe distant objects by their emission, Absorption (electromagnetic radiation), absorption, or Reflection (physics), reflection of electromagnetic radiation. Originally, it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodolite
A theodolite () is a precision optical instrument for measuring angles between designated visible points in the horizontal and vertical planes. The traditional use has been for land surveying, but it is also used extensively for building and infrastructure construction, and some specialized applications such as meteorology and rocket launching. It consists of a moveable telescope mounted so it can rotate around horizontal and vertical axes and provide angular readouts. These indicate the orientation of the telescope, and are used to relate the first point sighted through the telescope to subsequent sightings of other points from the same theodolite position. These angles can be measured with accuracies down to microradians or seconds of arc. From these readings a plan can be drawn, or objects can be positioned in accordance with an existing plan. The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronicall ...
