"I see what you mean, boss. But now we can''t continue the experiment like this! " Cohen pulled Lin Feng out of the machine room.
"Why?" Asked Lin Feng.
"Boss, what you said just now reminds me of a previous paper on the mystery of human brain." Brian Cohen is in memory.
Brain, including brainstem, diencephalon, cerebellum and telencephalon. The telencephalon includes the left and right cerebral hemispheres. Telencephalon is the main part of the higher nervous system of vertebrate brain, which is composed of left and right hemispheres. It is the largest part of the brain in human. It is the higher nerve center that controls movement, produces sensation and realizes higher brain function. The telencephalon of vertebrates is an expanded part of the thin wall at the end of the neural tube in embryo, and then develops into two hemispheres of the brain, mainly including the cerebral cortex, cerebral medulla and basal nucleus. Cerebral cortex is the gray matter on the surface of telencephalon, which is mainly composed of cell bodies of neurons. The deep part of cortex is composed of medulla or white matter formed by nerve fibers. There are also gray matter masses in the medulla, that is, the basal nucleus, of which the striatum is the main part.
The telencephalon is composed of about 14 billion cells, weighing about 1400 grams. The thickness of the cerebral cortex is about 2-3mm, and the total area is about 2200 square centimeters. It is estimated that about 100000 brain cells die every day (the less brain is used, the more brain cells die). The capacity of a person''s brain to store information is equivalent to 10000 libraries with a collection of 10 million books. The previous view was that people who are the best at using the brain only use 10% of their brain ability in their life. However, modern science has proved that this view is wrong. Human beings use 100% of their brain, and there are no idle cells in the brain. The main component of the human brain is water, accounting for 80%. Although the brain only accounts for 2% of the body weight, its oxygen consumption is 25% of that of the whole body, and its blood flow accounts for 15% of that of the heart. The blood flowing through the brain in one day is 2000 liters. The brain consumes about 25 watts of electricity.
"Well, well, stop, Cohen. Are you giving me a human anatomy class? I''m dizzy when you say that." Lin Feng quickly stopped Cohen from continuing to explain, "I said, it seems that you graduated from the Department of electronic computing, not the Department of medicine. How can you understand so many aspects of human body?"
"Ha ha, boss, I have a double master''s degree from the Department of electronic computing and the Department of medicine!" Said Cohen ostentatiously.
Lin Feng is speechless. Well, they are such talents from famous universities like Harvard or Yale in the United States. They are all powerful people. There are always double master''s degrees and even double doctor''s degrees. Thoreau, who studies Tesla notes for himself, has double doctorates. His Applied Physics, theoretical physics, and master''s degree in engineering are just incredible. Talking with them, you will often find that your brain is not enough and their knowledge is too profound. It''s exaggerating. It''s not human.
"Boss, according to modern scientific research, when the human brain works, it will produce its own brain waves, which can be detected by electronic scanners. There are at least four important bands. Studies have shown that there are at least four different brain waves in the brain. 1“ α”（ Alpha) brain waves, whose frequency is 8-12hz. When the human brain is in a completely relaxed state of mind [empty state], or when the mind is focused, the brain waves appear. In the "relaxed and active" state, we can absorb information more quickly and effectively. That''s the state we usually get by doing some kind of meditation or listening to relaxing music. Some of the contemporary popular "fast learning" skills are training methods based on the background of "Baroque" music, that is, the speed of many Baroque music works (60-70 beats per minute), which is similar to the "wavelength" of the brain in the state of "relaxed alertness". If someone reads the message to you with that kind of music, it will "float into your subconscious."
Lin Feng felt dizzy again.
"I said, Cohen, you can''t just say it." Lin Feng had no choice but to say, "I have a high school diploma. You have to give me such advanced knowledge. I can''t understand it. To be simple, I can understand it too!"
To be honest, Lin Feng sometimes has a little bit of inferiority in the face of people like Cohen. They are too able to learn. What''s more, they are not the nerds we think they are. For example, although Cohen has a double master''s degree, he is also a swimmer. His swimming skills are very good. It is said that he once won the bronze medal in the National College Swimming Championships when he was in college. Being able to read books and be good at sports is the rhythm of Diao blasted sky.
If you are not reborn, you are the loser among the losers. It''s a bitter tear to think that someone else is a loser and he is the loser. Fortunately, I had a good fortune and was unexpectedly reborn.
"Well, to put it simply, to put it simply!" Cohen sorted out his ideas and told Lin Feng in the simplest possible words, "there are four kinds of brain waves. The first one is“ α”（ (alpha) brain wave; The second is“ β”（ The frequency of EEG is 14-100hz; The third one is“ θ”（ The frequency of EEG is 4-8hz; The fourth is δ”（ The frequency is 0.5-4 Hz. "
"Among the four kinds of brain waves, the first is in charge of learning, the second is in charge of thinking and action, and the third and fourth are those that relax and let the brain rest. And the transmission of these brain waves depends on the transmission of 100 billion neurons in our brain. Therefore, for the Department of theoretical physics, only human brain waves can surpass the speed of light. Of course, at present, brain waves can only be transmitted in the human brain, not beyond the human body. And how much data can our brains store? Boss, guess what, according to the research of modern scientists, it can be calculated by using the hard disk space of the computer. " Cohen said with a smile.
Lin Feng''s mouth is curled. It''s at least a few megabytes! Lin Feng pondered.
This 1t is the capacity of 1000g, while 1g has 1024m, 1M, which can store about 500000 men. 1g has about 512 million Chinese characters. As for 1t, that is 500 billion Chinese characters. A few megabytes, the number of words stored, has long exceeded the total capacity of all books in human history. Lin Feng always thinks that it should be the same.
"Ha ha, boss, I said that the human brain has 100 billion neurons, and there are trillions of synaptic connections between these 100 billion neurons, forming a labyrinth of network connections, connecting the units where we finally store information. According to the estimation of modern scientists, each unit can hold about 2.5 gigabytes, which can hold 3 million hours of TV programs. Converted into today''s units, is almost the boss you said so much! It''s about 2.5 megatons. " Cohen said with a smile.
Lin Fengyan was completely shocked. Well, in this way, isn''t the human brain nearly infinite in capacity. You know, there are trillions of pipeline connections in the brain, and each connection is a unit. 2.5 trillion T, multiplied by trillions, this figure is too beautiful for Lin Feng to imagine.
"Ha ha, boss, this is the result of modern scientists'' research on human brain. As for why the human brain can''t actually store so much information, it''s also very simple, because our brain receives too much messy information, and these information, maybe we don''t feel, or even have no memory, but still occupy storage space deep in the brain. Think about it. If we just open our eyes and look at the world, there are many t''s entering our brain units. " Cohen said with a smile, "maybe we don''t think the information is important or even meaningful, but when we close our eyes and imagine, these seemingly useless and disorderly information is the basic existence of our imagination space."
Lin Feng thought about it, indeed. Well, that''s true. For example, the first thing I do when I get up every day is to dress. Then the brain will come up with the scene of where I left my clothes last night. This information is naturally recorded in the brain before going to bed last night. This information will occupy the brain unit space. Basically, people''s words and deeds need all kinds of information in the brain to support people''s actions.
"As for why some people have a good memory and others have a poor memory, it will be very complicated to explain. Therefore, I won''t explain to you. Otherwise, I''m afraid, boss, you need to study human biology. " Cohen said helplessly.
"Well, I don''t want to know that now. I just want to know what you said about Nuwa. " Lin Feng talks about Nu Wa.
"Boss, I keep asking myself," Nuwa "should have given birth to an intelligent life, but why did she not grow up as we expected? We showed her a lot of books and videos, but why did her IQ and EQ not get much improved. She still can only blame linear processing problems, rather than universal processing problems. I wanted to come for a long time. Finally, boss, you just said that you asked Nu Wa a lot of boring questions, and I woke up Cohen sighed, "if a person is locked up in a blank room all day, there is nothing in it, except some books, even if he can recite all these books, he is just a knowledge base. If you ask him to use this knowledge to do something, he will certainly not be able to do it. Why we human beings have the ability to create and solve problems lies in the fact that we have been trying to solve all kinds of problems since childhood. For example, walking, climbing, building blocks, building Rubik''s cube and so on. These are the inevitable experiences of human beings in the process of growth. And these are training our brain''s ability of thinking and logical processing! " Cohen pointed to his brain.
Lin Fengwen thought deeply.
"But Nu Wa didn''t have the chance. She has no room to grow up, so how can she grow up. All she has done is that I program for her, and she uses these programs to deal with all kinds of problems. In fact, what she did in this is just like what I said, people in a room are endorsing, that''s all. No matter how many books are on the back, they are just endorsements. Nuwa is the same. No matter how many programs she has, she is just running them. She doesn''t have to do anything Cohen said with a sigh, "it turns out that we have been wrong all the time after working so hard."
"But when I asked her those questions... I see, it was endorsement!" Lin Feng suddenly.
"Yes, that''s endorsement. She has been endorsing since she was born, when we tested her thinking. All these years, she has been endorsing. She is still like a baby, even more than a baby. The baby will at least laugh, the baby has five sense organs, so the baby will feel comfortable, or feel uncomfortable, or laugh or cry. But Nu Wa didn''t have all this. At present, she is just a placenta Cohen said with a wry smile, "I mistakenly thought that artificial intelligence life was really born. It turned out that it was just my imagination! To create a life, maybe it''s really something God can do! "
Lin Feng frowned. This is not what Lin Feng wants to see.
"Cohen, you gave up?" Asked Lin Feng.
"No, how can you give up! Boss, the conversation you had with Nu Wa just now woke me up and made me realize that all my past efforts were wrong. This represents that my past efforts are absurd, but it also shows me a clear way. Although Nuwa is now the placenta, it is also the placenta. As long as it''s placenta, it could be a life, a real life. And now the rest of the world, or companies, do not even have a placenta. Even they didn''t realize it. So, we still occupy a higher level than others. " At this moment, Cohen regained his confidence.
Artificial intelligence life, which is the most difficult breakthrough in the field of human science. But he has found an opportunity, a real opportunity. How can this not make Cohen proud.
"So what are you going to do?" Asked Lin Feng.
"Boss, I''m going to start from two aspects about cultivating Nuwa. One is to increase its computing power and storage space. In the past, I thought that we had enough storage space, but when I think about the human brain, I think that our storage space is far from enough. And the reason why the human brain has such a large storage space is that the human brain needs space to think. Thinking, when we think, can simulate the atomic bomb explosion, can simulate the destruction of the earth, and even can simulate the birth and destruction of the universe. It takes a lot of space, so our brain needs a lot of space. But at present, Nu Wa can''t think, from the hardware, the storage space is far from enough. So, the first step is to increase its storage space! " Cohen said.
