While researching the greatest chemists that have ever lived, I could not help but notice one who was missing from the list. Boyle, Mendeleev, and Lavoisier were on everyone’s list; and rightfully so, but I believe that people overlook the outstanding work of Henry Louis Le Chatelier. Le Chatelier studied chemistry extensively in school and made great discoveries as a teacher of the science at colleges in France. He is most known for the principle named after him: Le Chatelier’s Principle, which I will go into detail with later in the paper. My goal in this paper is to bring to light the significance of Le Chatelier’s life and his work in the field of chemistry and science.
To achieve this goal I have organized my paper into four

All my life I maintained respect for order and law. Order is one of the most perfect forms of civilization (L. Guillet)”. As a child, Le Chatelier attended College Rollin where he studied engineering (Henry Louis Wiki). When he turned 19, after only one year of instruction in specialized engineering, he followed in his dad's tracks by enrolling in the Ecole polytechnique on October 25, 1869. Like all the scholars of the school, in September 1870, Le Chatelier was named second lieutenant and took part in the Siege of Paris against the German and Prussian forces. After dazzling achievements in his technical schooling, he entered the Ecole des Mines in Paris in 1871 which was a prominent French engineering school at the time (Lette).
During his life he married Genevieve Nicolas and they had four daughters and three sons. Five of his seven children went on to enter scientific fields (pdf).
Le Chatelier’s Career and Scientific Work
Le Chatelier spent two years from 1875 to1877 as a mining engineer in the provinces, and after this period he returned to the Ecole des Mines as a chemistry lecturer in 1877. There he had a well-equipped laboratory that he could use for testing and research by contributing to the Firedamp
In the time before King Louis XIV’s reign, 17th century France was involved in several civil wars, there were no secure borders and the aristocracy acted as local rulers. In 1643 when Louis XIV came to power, he thought that he needed to secure both France and his own rule. He decided to build a new palace complex 12 miles outside Paris. To him, isolation meant security, he would be away from the plotters and schemers in Paris. He also believed that having all government departments and ministries living within Versailles would centralize the government and create reform.
Have you ever wondered what makes a serial killer tick and sets them off? What makes them want to kill and what is their drive to continue this horrible, sickening journey through their life or what was the cause for them to change their nature in life and create them into these monsters that we see them as today. It takes tragic experiences to cause that like abuse whether it is verbal, physical, or even sexual to cause a sense of damage to a person’s mind and disrupt their ability to comprehend what is sane and not. Well, Edmund Emil Kemper III had all of the makings of becoming a serial killer due to his troubled childhood.
“After having made a few preparatory experiments, he concluded with a panegyric upon modern chemistry, the terms of which I shall never forget: ‘The ancient teachers of this science,’ said he, ‘promised impossibilities and performed nothing. The modern masters promise very little; they know that metals cannot be transmuted and that the elixir of life is a chimera but these philosophers, whose hands seem
To conclude, the data we have collected from both experiments suggests that Le Chatelier’s principles are applicable and correct. When different substances were added to different solutions, the equilibrium shifted appropriately in order to gain a balance. The shifting of equilibrium resulted in different color changes in different mixtures. In part 2 of the experiment we the aforementioned changes were more easily spotted. We saw the relationship between forward and reverse reactions. When NaOH was added to tube #8 we saw that the color changed from orange into yellow, in order to gain balance but when we added HCl back, the color again changed to orange. Which clearly proved Le Chatelier’s
In today’s American society, the every day lives and routines of American citizens are impacted, affected, and ruled by the government. By studying the lives of people beginning in eighteenth century France, it is easy to see how the ruling government system impacts the everyday lives and routines of it‘s citizens. It is also easy to compare this society to the European civilization under the rule of Napoleon I, the American civilization under the rule of Woodrow Wilson, and Adolf Hitler.
Both men had a common ability to see the goodness in other men as royal
Louis Malle 's Pretty Baby was released in 1978. It tells a story of a brothel in New Orleans, Louisiana, in 1917. New Orleans was known for its red light district at a time; prostitution was legalized there in a period between 1897 and 1917. The film offers a glimpse of the last months of the brothel 's life. Pretty Baby is a story of Violet, a 12-year-old girl, who is a daughter of one of the most famous prostitutes in a brothel. Violet is pretty, brutally honest, and does not know life outside the brothel. In some time, Violet 's virginity is auctioned off and she is expected to become a prostitute, like her mother. However, falling in love with a photographer, who is always present in a brothel and takes picture of prostitutes, she runs away from the brothel to his house. The photographer takes care of Violet until she is picked up in the end of the movie by her mother, who had met a respectable gentleman ready to take her and her kids away to start a new life.
three children!He also married some other woman but they had a divorce with him and he also had
He had 4 daughters and a wife. Sadly his wife died in 2002. They lived with many many cats. He wasn't just author he made short films on a television. He won many awards including, Damon Knight Memorial Grand Master Award, National Medal of
Although Louis XIV, also known as Louis the Great, brought death and destruction through his wars, there are many positive aspects of his reign, such as the creation of Versailles and the building of France’s national army. He did what had never been done before. He changed the lifestyle and the attitude of France by creating one of the most powerful monarchies ever to be built and at the same time, reassured all the nobility and other wealthy groups of their political and social standings. He made it clear that he was the final decision maker yet he still needed the help of the nobility and other authorities.
The book “The Periodic Table” by Primo Levi is undoubtedly a masterpiece. It showcases the enthusiasm, the level of dedication, and passion successful chemists such as Primo Levi himself had for the field of their expertise. The way Primo Levi has related the troublesome times and events he had to face in prospect with the elements of the periodic table is laudable. Primo Levi is surely an inspiration and a perfect example of prodigy and passion. Despite the challenges and the hardships inflicted on him by the bigoted group of Germens, he still managed to emerge as an exceptional chemist and an author who made great contributions to the modern chemistry as we now know it.
Louis XIV had a passion for glory and used it to fight four wars because he was motivated by personal and dynastic considerations.
My chemist Luis Federico Leloir Luis Federico Leloir was born on September 6, 1906, at 81 Avenue Victor . Leloir graduated from the University of Buenos Aires medical school in 1932. While performing research at its Institute of Physiology from 1934-35, he worked alongside Professor Bernardo A. Houssay, who influenced his interest in adrenalin carbohydrate metabolism. Leloir spent a year at the University of Cambridge's Biochemical Laboratory before returning to the Institute of Physiology, where he studied the oxidation of fatty acids. After traveling to the United States in 1944, he worked as a research assistant in St. Louis, Missouri, and at Columbia University's College of Physicians and Surgeons in New York. Leloir won the Nobel Prize
Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry, all organic substances were understood
At first, he failed at this degree but then later passed and earned a general science degree in 1842. After two tries to enter, Louis was now in École Normale Supérieure which is like graduate school in today’s world (Tames n. pag.). He then received a Bachelor of Science license and began teaching physics at the Collège de Tournon. Louis did not stay there long as he joined Antoine Jèrome Balard at the École Normale Supérieure where he began his research and wrote his theses. In 1848, he was a chemistry professor at the University of Strasbourg (“Louis Pasteur”). There, he met Marie Laurent who he later married in 1849; they had five children together. Out of five children, two of them survived to adulthood, and the other three got the disease called typhoid and died at an early age (Tames n. pag.).
