As the cold days continue, I find that wearing a mask can help me survive the cold a little. I don’t know the infection-preventing effect of hygiene masks, but it keeps the face warm.
I remember that about a year ago
the dustproofness and breathability of various masks were constantly discussed, but it seems that such things have not been discussed recently.
Over the past year, newer viruses have been identified, rather than a single type. Compared to this topic, the basic performance of sanitary masks may not be important.
After all, if you stick some piece of cloth or paper to your mouth, your etiquette will be adhered to. Doing so makes me suffocate in the summer, but warm in the winter.
So I wore a mask, put earphones in my ears, and walked.
What are the leading resources of the next society?
Needless to say, human civilization is inseparable from the use of tools.
Tools can be roughly divided into basic tools and applied tools. A typical basic tool is fire. By using fire, applied tools are made.
Fire is a basic tool, but its discovery is a coincidence, and its mechanism is a natural phenomenon or a chemical reaction. On the other hand, there are intentionally made artificial basic tools. It’s electricity.
The savage society has progressed further with the use of fire, but in modern societies fire is rarely directly useful. The leading tool in modern society is electricity.
But even electricity will not be able to maintain its leading position forever, as long as it is produced by a certain process. In the next society, the power to generate electricity will gain a leading position.
Of course, the road to achieving that is expected to be steep. Like it took a long time for a savage society to be able to control fire.
When I was listening to music with earphones while receiving a dry wind, static electricity ran and my ears hurt slightly. I experienced this for the first time.
It seems that the cord of the earphones touched the synthetic fiber jacket many times and static electricity was accumulated. Then, something triggered the discharge.
However, suddenly feeling static electricity is not pleasant. What should i do?
