I think these two inventions are the greatest, and they are not prioritized. They both play a very important role in contemporary society. If either one is missing, it will be detrimental to people. Here, first of all, thank you. The man who invented the airdrop and the computer.
?1. Air conditioning
I used to have no air conditioning at home, and it was extremely hot in the summer. I would blow the fan all day long, and it would get hotter and hotter. I couldn’t sit still, and I was very irritated. , the enthusiasm for work will also be slightly reduced. Sometimes it is too hot and I don’t want to go to class, so I go swimming every day.
If there is a natural wind, it will be cooler, but this summer does not happen every day. There are only a few days occasionally, but who has the leisure to sit under a big tree to enjoy the coolness every day?
On such a hot day, I can’t even fall asleep at noon. Poor sleep seriously affects life and work, and also affects physical health. At night, when the sun sets, the temperature drops, and you can only fall asleep in the middle of the night.
After summer, can winter be far behind? After an autumn, winter will come soon. The climate in our south is not very cold yet, but in the north, the north wind is howling, the snow is flying, and the snowflakes are falling on the ground, on the roofs, and on the roads. It can be seen that the weather is extremely cold. Even if you wrap yourself up tightly and put on a down jacket, you will still shiver from the cold while sitting at home, let alone going out to do things.
My friend went to work in the north after graduation. She is a southerner. Suddenly she arrived in the north and the weather was too cold to adapt. She said to me, thanks to the inventor of the air conditioner, he gave me warmth. This winter will no longer exist. cold.
It can be seen that air conditioning can drive away the heat for us, and it can also bring us scorching heat. I can’t imagine that one day without air conditioning, people will be as hot as a pot of boiling porridge and as cold as An extremely cold popsicle.
With air conditioning, some disasters can be avoided. For example, in summer it can greatly reduce the number of people dying of heat stroke, and in winter it can reduce the number of elderly people on the streets who freeze to death. Therefore, people cannot live without air conditioning. , the invention of air conditioning is the greatest, but the computer is not inferior.
2. Computer
I heard from my mother that before there were computers, work was very hard. Cadres, when doing calculations, have to calculate for several days and nights, and it takes a lot of effort and brains, but it may not be correct.
Before computers, a company’s profit would not be much in a year. Compared with accountants, it would take several months to calculate the balance sheet and income statement, and the number of people hired by the company would also increase. . Research and development work will also increase.
With the advent of computers, the profits of the entire company have increased, and the workload of employees has also been reduced. The quality of work has been maintained and the corresponding work has been completed efficiently. Even if the wages of hundreds of people have to be calculated, It can be done in one day without making any mistakes.
Let’s talk about solving crimes, surveillance, and medical treatment.
Before computers, it was very difficult for the police to solve crimes. Because there were no computers and surveillance systems installed, many criminals escaped. It took years or even eternity for them to be caught and brought to justice. They could not solve major cases at all, and the society was in turmoil. Even more dangerous, people's lives will also be threatened.
In terms of medical treatment, medicine was very backward before computers. With computers, medicine has advanced by leaps and bounds. A lot of medical equipment has been introduced, all relying on computer monitoring and analysis. Many hidden conditions can now be diagnosed through Computer examination detects it and then treats it as soon as possible.
With computers, it has helped the development of medical treatment, technology, and military. Without computers, society may return to before liberation.
Therefore, air conditioning and computers are the greatest inventions of our time.
