When is useful & when is not?


On the previous blog, I have discussed few things, which are important to all the lives, and without those things, nothing can be alive. And this time I am going to talk about my thought when it is useful, when is not.

I decided to discuss Air, which is the most important thing in those three elements although we cannot lives without the other two things and there is some evidence to show that air is very important.


Air is one of the four elements(air, fire, water, and earth), and it is an atmosphere around us all the times. Inside air, it mixes with many gases and dust particles (the mixtures with such as nitrogen, oxygen, argon, carbon dioxide, water vapour etc.), it has no smell and invisible, it has mass and weight also it create an atmosphere. 

As the information above inside air, it mixes with oxygen which is most of the lives need weather is human or animals. Our blood is given oxygen by our lungs, then we give back the air carbon dioxide and that is the cycle breathing process of human and animals. On the other hand, plants are in a totally opposite situation, they absorb carbon dioxide, and give out oxygen. Therefore, we are helping all the lives let we breathe again. 

Air is moved by the wind, which helps the earth to dilute most of the pollution in the air. Nowadays, the industrial pollution is extremely serious, and it creates many problems that are affecting lives. For instance, Global Warming the causing by “greenhouse effect”, is a massive problem of all the lives in the earth, it changing the world every day, every second, every moment. Secondly, it totally influences lives health, we will get different kinds of weird disease because of that.

What makes aircraft can fly to the sky? They use a propeller to move the air over a wing, and pneumatics use air pressure to move things.



After the discussion about when it is useful, and now I am going to talk about what situation air become useless. We said that air is a mixture of many things, which around all over places. However, at the same time, there is a situation that has no air in it. And first, is the massive, mystery place where human still does not really know all the thing about it named Cosmos, it also called Universe. In some of the information says Universe has a very small number of particles and tiny bit of gas but here is no air in it, because the definition of air is, a mixture of many different gases, and we cannot find there are few gases in it so we would say that there is no air in the Cosmos. Furthermore, gas has no shape so the volume of gas can be infinite, is unlimited, and when there is no gravitation to constraint the gas, it will disperse afterwards. In addition, sonic can only propagate through the media and sound can be transmitted through gases, liquids and solids. Therefore, in a normal situation when there is no air, which is the main media for propagating, then we cannot hear any sound. But at the moment we still do not have this high good technology to create an Absolute vacuum (means there’s no any substance in the space).

On the other hand, human use this concept into our daily life. For instance, vacuum packing is one of the common things in our lives, and the main effect is to reduce oxygen in order to store the dry food be fresh, lightweight, and anti-corrosion, it also has another benefit such as moisture-proof,dust-proof,and anti-bacterial . 

Overall, air is a thing that which must be around us all the time, without the air we cannot be alive. Although there is a special situation for people to save their food longer, it still has a bit of air in but less oxygen. Also, air is always with the wind, they always been together. The Wind is not only one of the elements of the four elements but also it has the similar feature as air. It is no smell and invisible but we can notice them through feeling.

There are some pictures are taken in one of the studies(The Forgetting and Remembering of the Air), and it shows some of the information I have discussed on the above.



Forgetting and Remembering the Air

People become blind, so they do not SEE the world. But in here it, it does not actually mean people are physiological blind, but they are blind in a psychological way. People cannot see the earth, our world, and because of this, they always forget something which is very important and without those things we cannot be alive, the human world would not exist. For this, we can know that how important they are, but we still keep forgetting them. They are air, dust, and winds respectively, which are the most pervasive presence, it goes all over the places, from inside to outside, from our body to the whole world. There is something I really agree with is about: Lives cannot leave with water, air, food ingestion, and radiation, without those things it became nothing. Sometimes, we are in an empty space, and we think it is empty but in fact, the atmosphere is full of air and dust. Without air, we cannot breathe and the organisms would not be alive, and without dust, the world would be black, and it would be unrecognisable. It makes colours were being seen, it shapes many things from the seasons to buildings. And the last thing is the wind, which is the exist everywhere full over the world too. Although it is invisible, people can still feel it, so there’s no reason people can forget it. The only reason is people ignore it and pretend that they cannot see it, but actually, they are doing on purpose. On the other hand, our empty space is filled by radio waves, communication channels, and wi-fi thence, people lose communication with the human world. In the world, it filled by air, dust, and wind at the same time, and we cannot live without any of them.

Here is the narrative that we wrote about, and we thought a topic which is interesting to consider about. What came first? The Pollution or the Beechams? We have to produce something to protect our life, but at the same time, we are harming ourselves by it.
