Milia du Chtelet, a French scientist, is well known for his famous work, “Letters to Clairaut”, which deals with the conservation of energy. He was also a great friend of Voltaire. The article explores the relationship between the two, along with the nature and propagation of fire.
Essay on the nature and propagation of fire
In 1738, the French Academy of Sciences sponsored a contest on the nature of fire. Two competitors submitted their works, and the winner was Leonhard Euler.
One of the competitors, the Marquise du Chatelet, wrote an essay about the topic. Her work, which was based on her own research into the science of fire, became a major turning point in her career.
Du Chatelet wrote her thesis under the guidance of Pierre-Louis Moreau de Maupertuis. Her dissertation on the nature of fire was published in 1737. The book discussed the nature of matter, space, and fire. It also addressed the idea of energy conservation.
Du Chatelet’s translation of Newton’s Principia Mathematica, and her commentary on the work, are still considered to be standard in France. She also made a number of other contributions to the subject. For example, she introduced the concept of infrared radiation, which has become a major field of study today.
During her lifetime, Du Chatelet also published two other scientific projects. She wrote a critical analysis of the Bible, as well as other scientific works.
Letters to Clairaut
The writings of Emilie du Chatelet, a French physicist, have been widely studied. Her contribution to the science community includes a translation of Isaac Newton’s Philosophiae Naturalis Principia Mathematica and Institutions de Physique.
Euler wrote a congratulatory letter to Chatelet in 1740. At that time, Euler was in St. Petersburg. However, he had not yet read Du Chatelet’s Institutions de Physique.
In the late seventeenth and early eighteenth centuries, savants sought a deeper understanding of physics. They posed questions like how to accurately measure the force of a body in motion. Some natural philosophers sought to reduce rational mechanics to axioms.
When Chatelet’s Institutions de physique came out in February 1741, she had not yet received a response from Euler. However, her reply to de Mairan helped to establish her intellectual credibility.
Although Euler did not read Du Chatelet’s Institutions of Physique, he was impressed by her intellectual brilliance. He also sent her a letter thanking her for her work. This correspondence is preserved in the Leningrad Archive of the Soviet Academy of Sciences.
Relationship with Voltaire
The relationship between Voltaire and Emilie du Chatelet was an intellectual and culturally significant partnership for many years. Both contributed to the development of scientific thought and wrote many works on a variety of subjects. However, their relationship ended after 1745.
In the early 1730s, du Chatelet began taking lessons from Pierre-Louis Moreau de Maupertuis. Through these lessons, she developed a deeper relationship with her teacher. Du Chatelet also spent time at the laboratory of Louis Nicolas le Tonnelier de Breteuil, a high-ranking official of Louis XIV.
She also studied mathematics and science on her own. She was later commissioned to translate the first edition of Newton’s Principia Mathematica into French. From 1745 until 1759, she worked on the manuscript. This work was published anonymously.
At the same time, Du Chatelet began working on the Foundations of Physics. This book integrated the concepts of Leibniz’s metaphysics and Newton’s physics. It was a work that reflected the philosophers’ views.
There are many different interpretations of the final words of Milie du Chtelet’s conservation of energy. Some people say that Du Chatelet’s book is a reaction against Cartesian natural philosophy. Others say that it is a response in favor of Newtonian physics. However, no matter how one interprets her work, it was an important contribution to the advancement of science in France.
The final words of Du Chatelet’s conservation of energy describe her efforts to explain the relationship between physics and metaphysics. She did so by analyzing the methods of leading physicists of the day. She also argued for the role of god in the creation of the world.
As a result of her work, she was elected to the Academy of Sciences of the Institute of Bologna in 1746. She became the first person to quantify energy. In her experiment, she measured the amount of material that was displaced by the force of a heavy lead ball. This resulted in the discovery of the conservation of total energy.
