facial expressions. Marie-Anne immediately attracts the viewer’s attention through her direct, outward gaze. Tiny spots of light in her eyes combine with the light pink tint of her cheeks to produce a radiance that complements her slight smile. Lavoisier himself looks up, seemingly trying to make eye contact with his wife, but she is looking away towards the viewer. Rather than a smile, he appears to be displaying a more neutral expression, with no clear expression of emotion except the…

on Combustion in General Antoine Laurent Lavoisier was an 18th century French chemist who worked as a member of the the French Academy of Sciences. In the excerpts of Lavoisier’s Memoir on Combustion in General, he introduces to the other members of the Academy his idea of oxygen and its role in how combustion and calcination occurs. He also explains why the original theory of phlogiston, proposed by Georg Ernst Stahl, is not adequate to explain the two phenomenas. Lavoisier first explained his…

Scientific practice, although not originally thought of as scientific, started with simple questioning of the natural world. Originating as natural philosophy during The Enlightenment period, philosophes sought to understand the nature of mankind, and apply reason to comprehend the natural world (Hankins, 2). The earliest philosophes were wealthy aristocrats who met to discuss their revelations, limiting the sources of knowledge that contributed to scientific advancement. Throughout the early…

In eighteenth century science, the mechanical philosophy remained dominant with emphasis on understanding the composition, combustion, and fluids of matter. This led to an increase in identification and classification in both the physical and life sciences as scientists studied the properties of gases, acids, and bases. Thus, the eighteenth century was a time where the study of composition of matter, theories of heat, and electrical behavior of matter directed the physical science with…

“We must trust to nothing but facts: these are presented to us by nature and cannot deceive.” -Antoine Lavoisier. There are a lot of debates everyday about certain things, but there is one specific question that is discussed about all the time. People can never agree on this topic: Which is superior, reason or instinct? There are many situations where one of these things better than the other, but there are also times when neither of them are more important. However, reason is superior over…

what's inside of you right now was at some point in time was in a cow? The process of recycling atoms makes this possible. Everything is made up of a star that exploded in space a billion years ago. The Law of Conservation of Mass, discovered by Antoine Lavoisier in 1785, states that matter can not be created or destroyed makes the process of recycling atoms true/possible. When a person exhales out they are giving off carbon. The carbon then goes to a plant. There the plant intakes the carbon…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

The topic involves the relationship between acidic and basic solutions. Most people at one time in their lives have had stomach pain. Antacids are used to sooth your stomach (Fleishman). This project will test which antacids are the strongest. During the experiment there will be several test tubes filled with a “natural acid-base indicator” (Fleishman). Then, antacids will be dropped into each test tube. This will answer the question, “Which antacids are most potent in changing the color of the…

exceptionally receptive. Oxygen was found interestingly by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an 112, freely, found oxygen in 1774 and distributed his discoveries that year, three years before Scheele distributed. Antoine Lavoisier, a French physicist, likewise found oxygen in 1775, was the first to remember it as a component, and instituted its name "oxygen". Oxygen is the reason that we're breathing. Oxygen is enormously required forever. How does oxygen…

apartment of the Grand Duke Paul of Russia’s wife on the Christmas Day of 1781. Many scientific advancements also arose during that time such as the discovery of the law of conservation of mass, which lead to the beginning of modern chemistry by Antoine Lavoisier in 1789, and the development of the world’s first smallpox vaccine by Edward Jenner in…
