What practical knowledge do you find useful?

Now I find knowledge particularly useful, because I am a post-80s generation and am in the process of developing my family's career: there is a lot of pressure! The junior high school classmates at that time had similar family conditions!

Later, some did not go to college, some went to college, and now there is a big difference: those who did not go to college were hard work, and those who went to college were technical jobs! Most of them don't go to college to work outside, and their children stay at home with their grandparents; When you go to college, have a stable job, put your children by your side, and when you talk to others, well-informed people are always especially likable!

I am very satisfied with my customers because of my professional knowledge at work! Food, clothing, housing and transportation, some small tricks in life make me handy! When I was a first-time parent, I was especially useful in parenting!

When my child's 100,000 whys, I saw her look of adoration! In fact, I find knowledge especially useful at any time! Live to be old, learn to be old, and still have three points to learn!

In the process of making dumplings, there are many physics knowledge. There is a saying called "raw salty boiled light", that is, the boiled dumpling filling is lighter than the raw one, the reason is that the temperature of the dumplings rises when cooking, the irregular movement of salt molecules accelerates, and there are many salt molecules moving into the water, and the salt content in the dumpling filling will decrease. When mixing the noodles with the dumpling skin, use cold water, and cover them after the mixture, so that the temperature is low, and the air near the noodles does not flow, which effectively slows down the evaporation of water and avoids the drying of the dough.

Otherwise, the dough will not be tightly pinched when making dumplings, and water will enter when cooking. After putting the dumplings into the pot, to prevent the dumplings from sticking to the pan, gently push the dumplings in turn with a spoon or spatula. In this way, the contact area between the spoon or spatula and the dumplings is larger, and the same force is used to reduce the pressure on the dumplings to prevent the dumplings from being pushed through.

The study and living habits I developed in elementary school have benefited me for the rest of my life. For example, when I get home, I write my homework first and then play games, and my homework should be written neatly and cleanly, etc., as well as the basic knowledge from elementary school, Tang poetry, pinyin, arithmetic, addition and subtraction, etc., English is not very useful in work, and there are basically not many places where I can use it.

In the hot water bottle at home, the cork sometimes jumps out when filling boiling water, and the internal energy of the water vapor in the water bottle is converted into mechanical energy to work on the cork. The empty cans of milk powder that the babies in our family have eaten can be made into a knife holder with a few openings at the top end.

In summer, when we wash our face with hot water, we feel cooler than when we wash our face with cold water, because the temperature of hot water is higher than that of cold water, and the higher the temperature, the faster evaporation, and evaporation absorbs heat, so we feel cooler.

When we pickle pickles, it usually takes about 15 days to become salty, and when we stir-fry, the dishes quickly become salty, which is due to the higher the temperature, the more violent the ions in the salt, mainly sodium ions and chloride ions, move.

In life, when we boil water, we are accidentally burned by water vapor, which is often more serious than boiling water, because the water vapor liquefies into water, and a part of the heat is released.

The household appliances with metal shells in our homes are all plugged into three-pin sockets, and the purpose is to take safety measures to prevent leakage of electrical appliances.

The reason why the car rear view mirror is made of convex mirror, and the reason why it is not made of plane mirror is that the convex mirror has a divergent effect on light, and the observation range of the convex mirror is much larger than that of the plane mirror.

Knowledge is not only practical, but also romantic. When we learn knowledge, we not only acquire practical skills and information, but also develop our emotions, thinking skills, and creativity.

On the practical side, learning knowledge can help us solve various problems in life. Whether it's learning a new skill, learning about a new culture, or learning a new tool, it can help us be more productive, more confident, and better at quality of life. Through learning, we can better understand ourselves and the world around us, and better respond to challenges and opportunities.

When it comes to romance, knowledge also plays an important role. Through learning, we can expand our culture and horizons and learn more about human history and civilization. We can learn about different art forms and cultural traditions by reading literature and visiting museums.

Through learning, we can also better understand and appreciate the opposite sex, and establish deeper connections and communication.

Knowledge is not only practical, but also romantic. We can broaden our horizons and improve our thinking and communication skills through learning. Learning knowledge can help us better understand ourselves and the people around us, and build deeper relationships.

In the process of learning, we can also celebrate the void to experience romance and poetry, and feel the infinite possibilities and beauty brought by knowledge.

Because knowledge is limited, imagination encapsulates everything in the world, drives social progress, and is the source of knowledge evolution.

Let's take an analogy. Learning is like building a building with bricks, and each brick is like a knowledge point. And imagination is like cement that binds brick to brick. The more you can understand the logic between knowledge, the more you can increase the application of knowledge through imagination.

It's not that knowledge is useless. Many new discoveries must be based on existing knowledge. But to a certain extent, imagination can break the confinement of existing ideas. Just like no one dared to think that humans could go to Mars before.

Knowledge is both practical and romantic, and their usefulness and romance depend on the way and the context in which they are used. Here are a few moments that can make people feel the practicality and romance of knowledge: Hui Liangchun.

1.When traveling: When you're on the road, learning new languages, cultures, and histories will help you better integrate into the local community and better understand and appreciate the local culture.

At the same time, this knowledge also makes travel more fun, colorful, and surprising.

2.Cooking: Learning cooking techniques allows you to make delicious, healthy, and nutritious food.

Once you've mastered your cooking skills, you can experiment with different recipes and methods to create your own specialties and wow people at family gatherings or gatherings of friends.

3.Aesthetics: Knowing the history of art and design, as well as works of various genres, will allow you to better appreciate aesthetic values.

Knowing the history, meaning, and technology behind a painting or design allows you to better understand and appreciate a work of art, while also allowing you to demonstrate your cultural literacy in small talk with friends.

For example, knowledge of computer programming and data analysis can help you better process large amounts of complex information and provide smarter solutions at work.

In short, it is very important to have practical knowledge at all times. And when we understand and combine knowledge with life scenes, we will feel the romance and charm of knowledge.

1.Knowledge that has practical value is good knowledge.

Knowledge is useless if it does not change behavior; But as soon as knowledge changes behavior, knowledge itself immediately loses its meaning. - A Brief History of the Future

The pragmatic point of view is that knowledge that can be used in reality is valuable knowledge.

In other words: valuable knowledge is valuable knowledge. Knowledge without practicality, although not necessarily "pseudo-knowledge", is also useless knowledge and is not worth our efforts to learn.

So, what do you think about "practicality"?

First of all, "practicality" is a subjective concept. Some knowledge may be useful to me, but it may not be useful to others. Different people have different views on the practicality of knowing things.

The same knowledge is of great value to some people, but worthless to others.

Second, "practicality" is not an essential attribute of knowledge. No knowledge is naturally useful, we must digest and absorb it before we can apply it in our lives.

How can you tell if knowledge is useful?

First of all, try to conceive of a scenario in which this knowledge is actually used in your life, and if you can't conceive of this kind of scenario, this knowledge may be useless.

For example, if you imagine a scenario where a binary equation is used, can you think of any realistic scenario? In my life, I can't conceive such a scenario, so binary equations are useless knowledge for me.

Secondly, judge whether this knowledge can improve our ability and whether it can help us understand, analyze and think about certain problems. If the answer is yes, then the knowledge is useful.

The theory of relativity is of little use in real life, but understanding it can help us understand the world (the universe). Of course, it is difficult to learn the theory of relativity, and the practical value obtained in the end is not high, so as an ordinary person, I do not recommend learning the theory of relativity.

In any case, practical value judgment is the subjective law of the individual, and whether a knowledge is useful to you or not, you can only make a judgment on yourself.

Finally, it is easy to think of knowing knowledge as understanding knowledge, and understanding knowledge as knowing knowledge. Knowing, understanding, and applying knowledge are the three levels of learning, and only the ability to apply knowledge can have practical significance.

Knowledge is the culmination of human wisdom that not only helps us understand the world, but also guides us on the path to success. In life, there are many moments when we feel the practicality and romance of knowledge, let me share some of the moments I have experienced.

It was the first time I read an original English book.

In the process of learning English, I used to read a lot of English books, but they were all translated into Chinese. Until one day, I picked up an original English version of ** and began to try to read. At first, I encountered a lot of new words and grammar difficulties, but as I read more, I gradually understood the content and felt the charm of English.

This moment made me feel the practical use of knowledge, because English is a global language, and mastering it can help me communicate better with the world. At the same time, this moment also made me feel the romance of knowledge, because English is not only a language, but also a manifestation of a culture and way of thinking.

For the first time, I independently completed a complex task with the Zen Brigade.

In our studies and work, we are often faced with a variety of tasks and challenges. Once, I was given a complex task that I needed to complete independently. At first, I felt a little overwhelmed, but by researching, asking others, and trying again, I was able to complete the task.

This moment made me feel the usefulness of knowledge, because only through continuous learning and practice can I master the methods and skills to solve problems. At the same time, this moment also made me feel the romance of knowledge, because in the process of solving problems, I continued to explore and innovate, and experienced the fun and sense of achievement brought by knowledge.

Attend a cultural event for the first time.

Culture is the spiritual wealth of a country and a nation, and it is also the crystallization of human wisdom. Once, I participated in a cultural event that included performances and presentations in various forms such as **, dance, and drama. Through this activity, I not only learned about the characteristics and charms of different cultures, but also felt the power and influence of culture.

This moment made me feel the usefulness of knowledge, because learning about different cultures helps me to better understand and respect others, and promotes communication and integration between different cultures. At the same time, this moment also made me feel the romance of knowledge, because culture is the crystallization of human wisdom, it contains infinite beauty and wisdom, and makes people feel the meaning and value of life.

In short, knowledge is the crystallization of human wisdom, which can not only help us understand the world, but also guide us to the path to success. In life, there are many moments when we feel the practicality and romance of knowledge, and only by continuous learning and exploration can we better appreciate the charm and value of knowledge.

Knowledge alone is useless, but knowledge is very useful when it is cultivated into ability.

You can't live without knowledge, and knowledge is inseparable from everything in today's society, which should be regarded as equivalent to information.
