Origin:
The concept of an atmosphere was first proposed by the ancient Greek philosopher Aristotle (384-322 BCE) in his work "Meteorology". He believed that the atmosphere was composed of four layers:
Aristotle's theory was largely based on observation and did not have a strong scientific foundation. However, it helped to establish the idea that the Earth was surrounded by a layer of gases.
The term "atmosphere" was first used in its modern scientific sense in the 17th century by the English mathematician and scientist Robert Boyle. In his book "The Sceptical Chymist", Boyle described the atmosphere as a "fluid body" that surrounded the Earth and exerted pressure on its surface.
Over time, further scientific research led to a deeper understanding of the atmosphere and its composition. The discovery of oxygen and nitrogen by Antoine Lavoisier in the 18th century revolutionized the field of atmospheric science and laid the foundation for modern meteorology.
