It surrounds us during our entire lives, and we breathe it in and out from our first to our last moment. Without it, there would be no life on our planet. We are talking about one of the four elements, air. The air combines gases that make up the earth’s atmosphere. Dry air is mainly composed of two gases: Nitrogen (N2) is the primary air component at 78.08 percent. At 20.92 percent, oxygen (O2) is the second most crucial component.
Furthermore, air contains noble gases (0.93 percent in total), mainly argon, as well as helium, neon, krypton and xenon. In addition, carbon dioxide (CO2) makes up 0.037 percent, and is one of the main air components due to its importance for living organisms and the climate. The air also includes methane, hydrogen, nitrous oxide (laughing gas) and carbon monoxide. In this article of Gazettely, we will tell you nine interesting things about the air that you probably don’t know.
There is one who, through the air, have defined a new concept of sculpture, which is no longer based on the use of solid and heavy materials such as marble or bronze. The American Janet Echelman from 1997 gave shape to the spaces of cities with her suspended installations, which was created with sheets and nets. The idea came to her while observing a group of fishermen who were repairing their nets. Today Echelman – who has exhibited her works during significant events such as the Olympics – works with aeronautical engineers, landscapers and lighting experts.
