How much do humans know or how much do they not know?

Personally, I think that the so-called knowledge is just the law summarized by human beings in the process of understanding nature and changing nature, but human beings use it as a written form or oral recitation and other methods to continuously pass it down, with the development of human beings, knowledge will continue to be updated, and constantly present more and more updated things that are useful to contemporary and future generations, so the problem you mentioned personally thinks that there is no way to compare at all.

For medicine, you will find that human medicine has always lagged behind human diseases, human beings will always walk behind the disease, only after the disease appears, someone will begin to study how to treat this disease, human beings can not look forward to the disease that has not yet appeared, because there is no clue or follow to follow, so, you will find that many diseases can not be cured at all, but you can imagine that many years later, after our cancer and other diseases are overcome by human beings, Future generations are bound to encounter new diseases, and they may ask the same questions as you......This problem, I personally think that as long as human beings continue the current law of development, it will not be able to solve it......

Knowledge is the knowledge of nature, and even if nature is infinitely large and infinitely small, then knowledge is also infinite. Use a limited life to gain unlimited knowledge, work people and lose money. People-oriented, try your best to experience life, in order to gain wisdom, it is more valuable!

Knowledge is to arm oneself, we only learn a wealth of knowledge, use them to deal with various social problems, make correct judgments, only know whether they are right or wrong, in order to gain a foothold in the future society, so knowledge is not a bad thing, only by mastering knowledge can there be a future, but some bad knowledge advises you not to master, so as not to harm others and yourself!

Human knowledge involves many aspects, and sometimes the practicality and romance of knowledge go hand in hand. Here are some of the moments that made me appreciate the "practicality and romance of knowledge":1

When looking at the stars: People who are knowledgeable about astronomy can appreciate and understand the stars better, and the romance and beauty that come with this experience are unparalleled. In addition, mastering astronomical knowledge can also help us better understand astronomical phenomena such as solar eclipses, lunar eclipses, and so on.

2.When traveling: Understanding the historical, cultural, and artistic background of a destination allows us to better appreciate and understand the local architecture, attractions, and traditions.

This understanding makes travel more interesting and meaningful, while also giving us a deeper understanding of the diversity of different cultures. 3.Cooking:

Learning cooking skills not only allows us to make delicious meals, but it also increases our knowledge of ingredients and foods. Knowing what to do with the food allows us to better handle the ingredients, ensure the quality and hygiene of the food, and also give us a better understanding of the production and historical context of the food. 4.

When studying science: Understanding science can help us better understand the world around us, such as why the sky is blue, why insects can walk on water, and so on. This knowledge can help us better understand the mysteries of the natural world and help us better respond to environmental changes and crises.

5.When reading literary works: Understanding literary history and literary theory can help us better appreciate and understand literary works, while also giving us a deeper understanding of culture and the human spirit.

The romance and beauty that comes with this experience can make us better appreciate the diversity and beauty of human culture in Ganahu. In short, the practicality and romance of knowledge go hand in hand, and mastering knowledge allows us to better understand the world, better cope with life's challenges, and at the same time make us more sensitive to the beauty and diversity of life.

Put your knowledge into practice and contribute to society, that reflects your value! However, it doesn't take time, but it doesn't work, and accumulating more knowledge is not harmful. Don't "hate less when the book is used"!

1. Husband is the name of eunuchs in ancient times. 2. Read a book when you go to the toilet, remember it very well! 3. The first camel poop of a newborn is green.

14. Whether there was a chicken or an egg, according to the Bible, there was a chicken. 15. Except for south and north, the first words of the seven continents are all a year old oak. 16. Snot is phlegm.

17. It is said that the urine of cats is glow-in-the-dark. 18. Nokia was the first to make paper. 19. Students who want to be as tall as "One Piece" can have a bone crack first, and then they can increase their height after the bone cracking**.

1. Human beings are born with only one viewpoint: taking their own interests as the ultimate goal. (Don't think that this is a sin, there are many kinds of interests, if you also take into account the interests of others when pursuing your own interests, or take the interests of others for your own benefit, this is also a good thing) 2. Human beings form their own knowledge through everything that happens around them all the time.

Although you may not realize it yourself) 3. Empiricism: Everything that is similar on the surface should be similar in substance, and therefore the solution should be similar. This works well when things are usually happening, but it's too rigid to be flexible.

Rationalism: Analyze specific things and take corresponding measures to deal with them. It's flexible, but it requires a lot of brains and a long time, and it's cumbersome.

Personally, I feel that this is like the difference between classical mechanics and the theory of relativity: although the theory of relativity is more perfect, it is very troublesome, and it only shows its advantages when analyzing extremely high-speed cases, so Newton's classical mechanics has not been obsolete.

Only when you have understanding and thinking can you have a point of view, so there is no such thing as an innate point of view. When human beings begin to think and create, they slowly gain knowledge....

You can take a look at it here, I hope it helps you!

The British journal New Scientist recently listed 10 human behaviors that cannot be explained in detail, including kissing, blushing and even picking noses. According to the journal, "research itself is perhaps more important than studying its field."

It's only natural that we spend a lot of energy trying to figure out what these behaviors mean for humans. ”

Laughter: When humans laugh, they release mood-improving polyphenols. While this argument is compelling, a 10-year study found that repeating old tunes seems to make people laugh more than jokes, which in turn seems to contradict and confusing explanations of chemical methods.

Dreaming: Freud believed that dreams express the desires of the human subconscious. Although this statement does not yet convince everyone, they also admit that dreaming helps humans release their emotions. However, scientists do not know the cause of strange dreams.

Art: Human beings like painting, dance, sculpture and other arts, and are willing to show them to the world, while in the animal kingdom, animals such as peacocks will show each other that they are an ideal companion by opening the screen, singing, etc. Scientists believe that art can also spread knowledge and share experiences.

The Greek philosopher Zeno once compared knowledge to a circle, the circumference is what you know, and the circumference is what you don't know. The more a person knows, the larger his circle becomes, and the more unknown the circumference comes into contact with. Therefore, the more knowledge you have, the more you know you don't know.

The knowledge that man has is a circle, and beyond the circle is the unknown world. The more knowledge you have, the bigger the circle becomes, the more you are exposed to the unknown, the more confused you are, and the more you learn, the more you feel ignorant. Of course, people who think so must be humble in their hearts, and they must be introspective in ordinary times, and their thirst for knowledge is also strong, so that they will realize their own shortcomings, personal insignificance, and the vastness of the ocean of knowledge.

Otherwise, for a mediocre person who is satisfied with the status quo and complacent, he has long been carried away, how can there be such a sense of crisis of inadequacy?

It's like a circle, what you know is what's in the circle, what you don't know is what's outside the circle, the bigger the circle, the bigger the space outside the circle.
