Jacques alexandre charles biography

Among other artifacts that were developed by Jacques Charles, we can also mention the megascope, a useful tool in the projection of enlarged images. He also highlighted the hydrometer, known as a hydrometer. It is a glass device designed to measure the relative density of liquids, which can be calibrated for use in various industries and with specific scales.

In oenology this artifact is used to determine the degree of maceration in which a wine is found. In the dairy industry, the hydrometer is used to measure the creaminess of milk. In this industry it is known by the name of lactometer; It is also known by other names, such as saccharometer and breathalyzer, among others. The reflection goniometer is used for the measurement or construction of angles in mineralogy, especially for the measurement of angles in crystals with different faces.

It is also used to determine the type of crystal. In topography and engineering, the goniometer is used to measure angles and for triangulation; In addition, it allows determining the latitude of a star with simple calculations. The goniometer is also used in astronomy to measure the diameter of stars or galaxies, and in geodesy it is used for the triangulation of the territory in the creation of maps.

Some biographers consider that Jacques Charles did not achieve all that is attributed to him, but may have been involved in a confusion with another of his contemporaries, known as Charles the Geometer. The confusion between these characters may have been due to the fact that solid facts about Charles the Geometer are completely unknown.

Because of this, some claim that Jacques Charles may have lied about his admission to the Academy; however, this information has not been confirmed. Jacques Charles: Biography and Contributions.

Reportedly the poet Alphonse de Lamartine also fell in love with her, and she was the inspiration for Elvire in his autobiographical Poetic Meditation "Le Lac" "The Lake"which describes in retrospect the fervent love shared by a couple from the point of view of the bereaved man.

Charles outlived her and died in Paris on 7 April Charles conceived the idea that hydrogen would be a suitable lifting agent for balloons having studied the work of Robert Boyle 's Boyle's Law which was published years earlier inand of his contemporaries Henry CavendishJoseph Black and Tiberius Cavallo. Charles and the Robert brothers launched [ 6 ] the world's first hydrogen filled balloon on 27 Augustfrom the Champ de Marsnow the site of the Eiffel Tower where Ben Franklin was among the crowd of onlookers.

Daily progress bulletins were issued on the inflation; and the crowd was so great that on the 26th the balloon was moved secretly by night to the Champ de Mars, a distance of four kilometres.

The balloon flew northwards for 45 minutes, pursued by chasers on horseback, and landed 21 kilometers away in the village of Gonesse where the reportedly terrified local peasants destroyed it with pitchforks [ 7 ] or knives. Sand ballast was used to control altitude. Charles then decided to ascend again, but alone this time because the balloon had lost some of its hydrogen.

This time it ascended rapidly to an altitude of about 3, metres, [ 5 ] [ 9 ] where he saw the sun again. He began suffering from aching pain in his ears so he "valved" to release gas, and descended to land gently about 3 km away at Tour du Lay [ fr ]. It is reported thatspectators witnessed the launch, and that hundreds had paid one crown each to help finance the construction and receive access to a "special enclosure" for a "close-up view" of the take-off.

Simon Schama wrote in Citizens :. Montgolfier's principal scientific collaborator was M. Charles himself was also eager to ascend but had run into a firm veto from the King, who from the earliest reports had been observing the progress of the flights with keen attentiveness. Anxious about the perils of a maiden flight, the King had then proposed that two criminals be sent up in a basket, at which Charles and his colleagues became indignant.

The next project of Charles and the Robert brothers was to build an elongated, steerable craft that followed Jean Baptiste Meusnier 's proposals —85 for a dirigible balloon. The design incorporated Meusnier's internal ballonnet air cellsa rudder and a method of propulsion.
