Biography on Guillaume Amontons

 

Guillaume Amontons was born in Paris on August 31, 1663. Amontons is a French physicist.  He became deaf during his early childhood, which is caused his interests towards books and academia. As a youth Amontons, after working on several public works projects, applied his skills in inventing.He was supported in his research career by the government .

 

His father was a lawyer from Normandy who had moved to the French capital. Amontons never attended a university, but was able to study math, the physical sciences, and celestial mechanics. He also spent time studying the skills of drawing, surveying, and architecture.

 

One of his first inventions in 1687 was of an improved hygrometer, a device used to measure humidity and consisted of a mercury-filled ball that expanded or contracted according to the air's water content. Just a year later he made improved the barometer and the thermometer, mainly to use these instruments at sea. He also demonstrated an optical telegraph and proposed the use of his clepsydra, a water clock, for keeping time on a ship at sea.

 

Guillaume established that the pressure of a gas increases by about one-third between the temperatures of cold and the boiling point of water. This was a huge step towards the gas laws and Charles's law. He was the first researcher to discuss the concept of an absolute zero of temperature.

In 1699, Amontons published his rediscovery of the laws of friction first put forward by Leonardo da Vinci.

 

 

 

 

Background on the scientists discovery/advancement:

Guillame Amontons dedicated his life to the improvements of instruments employed in physical experiments. In 1687 he had presented a hygrometer to the Academy of Sciences that was one of his own inventions. This was used to measure humidity.  In 1699 he had performed some experiments dealing with friction, and then had written two papers on thermometry. His experiments had started with an air thermometer, where the temperature was measured by a column length of mercury. This had then led him to the pointing out of extreme cold of such a thermometer which would reduce the “spring” of the air to nothing. He was known as the first to recognize that the air being used as a thermometric substance would lead to his inference of a zero temperature. Although Amontons may had discovered a temperature so low that it’s close enough to become absolute nothingness, little evidence is represented in his papers that show he can be named the author of absolute zero. Amontons work had inspired the research of Johann Heinrich Lambert, and William Thomson who had invented the absolute scale or Kelvin scale in 1848.

Ways Amontons had impacted personal life:

 

Lindsey had found out that  Amontons had come up with improvements to the barometer, hygrometer, and thermometer which had allowed for them to be used at sea. He had also made a demonstration of an optical telegraph and had proposed his use and idea of the water clock which allowed you to keep time on a ship at sea. Now people have more advancements and easier ways to keep track of things while they are out at sea.

 

Brittany said that  Amontons became the first one to realize that there was an absolute zero that existed. Amontons had found out that there was an “end point” degree, which brought on determination of the other scientists to go out and find it.

 

Don found out that with Amontons' discovery/improvement in scientific instruments, he had invented a device to measure the amount of humidity in the air. Now, people in the world are able to find out the humidity levels for the day, and determine the weather without any complications or difficulties.
