Yes, the air has the weight. You know that there is a layer of air called the atmosphere on the Earth? The layer of air is attracted by the universal gravitation of the earth. To be attracted means that the air has weight. By the way, it weighs about 1.29 grams per liter of air.
I see. How did you inspire the theory that substances have attraction?
There was a lot of time to study when I was withdrawing at my home.It’s when a major epidemic faded in college days. I got a large amount of scholarship, so I did not have any problem with research expenses, but I could not find a new way to research and the idea was stalled.
One day, when I went outside for a rest, I saw an apple tree in my garden. At that moment, the apple fell.I realized that I didn’t know why does the apple fall? And then I proceeded with research on things falling.
I see. What kind of things did you use such technology in the past?
It is used in technology to calculate the trajectory such as a satellite floating in outer space and Space Shuttle which can sense the existence of universal gravitation greatly. In recent years the technology to calculate gravity is also used for planetary explorers and I hope that it will be useful for the future development of science.
Without an artificial satellite, we can not use the Internet, so we can say that the discovery of universal gravitation is still a great accomplishment! Thank you for coming today.
Thank you too. I have still other things that I left behind, so ask google!
