Think about the autonomic nervous system in dichotomy! ? The establishment of new medicine is achieved through the sympathetic and parasympathetic nervous systems! !

Hello. This is Tenmei Watanabe from Seito Medical School. This time it's a medical school report. We would like to publish the results of medical research to date.

The autonomic nervous system includes the sympathetic nervous system and the parasympathetic nervous system. By using the dichotomy between the sympathetic and parasympathetic nervous systems, we can understand the causes of many diseases.

Sympathetic nerves are high blood pressure, high body temperature, vasoconstriction, and high heart rate. If the sympathetic nervous system is dominant, there is a positive correlation with, for example, metabolic syndrome (visceral fat obesity that leads to lipid abnormalities, hyperglycemia, and hypertension). Metabolic syndrome is the cause of all kinds of diseases, and the sympathetic nervous system is dominant.

Furthermore, if the sympathetic nervous system is dominant, excess oxygen and metabolism will be promoted.

Several questions arise here. Since I'm interested in brain diseases, let's take a look at the relationship between the autonomic nervous system, which at first glance seems unrelated to the disease called cerebral infarction.

Cerebral infarction is a disease caused by blockage of blood vessels in the brain, but there is also "cerebral thrombosis," where arteriosclerosis progresses and blood vessels become clogged, and "cerebral thrombosis," which occurs when blood clots formed in the heart are carried to the brain and block blood vessels. There is a cerebral embolism.

I had the question of whether blood clots form due to low blood pressure or high blood pressure. Whether blood clots occur due to low blood pressure or high blood pressure, if the presence or absence of blood pressure is a factor in cerebral infarction, we can find a relationship between brain disease and the autonomic nervous system.

In conclusion, after a blood clot forms, blood pressure rises to allow blood to pass through the blood vessel blocked by the clot, resulting in high blood pressure. However, I don't know if I had high blood pressure or low blood pressure before the blood clot formed.

In order to confirm the strength of blood pressure when blood clots form, we will look into common factors such as complications. This reveals the fact that thrombosis is often a complication of obesity. In other words, it can be inferred that obesity is caused by sympathetic nerve-dominated hypertension, as seen in the metabolic syndrome, and that hypertension was the same before and after the formation of blood clots.

In establishing a new medical science called autonomic neurology, I would like to take this approach of finding commonalities from the symptoms and causes of complications. Furthermore, we treat the autonomic nervous system as a dichotomy of sympathetic nerves and parasympathetic nerves, and investigate which disease each disease belongs to.For example, in the case of hypertension, one treatment method is to lower the blood pressure, that is, the cause of hypotension. This means that we can expect it to be as follows.

So far we have talked about the sympathetic nervous system being dominant, but I would like to talk about the parasympathetic nervous system being dominant.

If parasympathetic nerves are dominant, there will be low blood pressure, low body temperature, vasodilation, and low heart rate. Parasympathetic nerves activate gastrointestinal activity.

Parkinson's disease is one of the diseases associated with parasympathetic nervous system dominance. Parkinson's disease presents with movement disorders such as tremors in the hands and difficulty moving or walking. Although it is considered to be a progressive neurodegenerative disease, onset is most common in middle-aged people over 40 years of age, especially in people over 65 years of age.

I felt that my hands were shaking and my movements and walking were slow, similar to how people react in winter. If Parkinson's disease causes symptoms such as hand tremors due to the same factors as people who live in winter, I feel that it would be interesting to investigate how the autonomic nervous system is related to people who live in winter. did. In other words, the assumption is that people with Parkinson's disease have the same reactions as people in winter.

In Japan, it is said to be caused by damage to dopamine neurons in the substantia nigra. Conditions other than Parkinson's disease that have similar symptoms are called Parkinson's syndrome. Many patients with Parkinson's disease also have dementia.

One of the key points is that Parkinson's disease gives the illusion of the cold winter weather, which may be due to a lack of amino acids, which results in no metabolism and a low body temperature. Metabolism is low and body temperature is low when parasympathetic nerves are dominant. Furthermore, if the parasympathetic nervous system is dominant, it can be inferred that there will be more or less low blood pressure and low heart rate.

Since many patients with Parkinson's disease have dementia as a secondary disease, it can be inferred that dementia is also a disease on the same side as the parasympathetic nervous system.

Furthermore, it is believed that dopamine is insufficient due to damage to dopamine neurons, and conversely, manic states such as schizophrenia and manic-depressive disorders, in which there is an excess of dopamine, are dominated by the sympathetic nervous system, which is the opposite of the parasympathetic nervous system. I understand.

Metabolic syndrome, in which the sympathetic nervous system is activated due to its relationship with obesity, occurs in many patients with schizophrenia, and patients with Parkinson's disease are often thin, so the parasympathetic nervous system is associated with thinness. I can see that there are.

In relation to dementia, which is a secondary disease of Parkinson's disease, parasympathetic-dominated symptoms such as excessive sweating, night sweats, and dilated blood vessels in the skin can be seen in dementia with Lewy bodies. An increase in body temperature is accompanied by a decrease in body temperature, indicating that the parasympathetic nervous system is still dominant.

In winter, there is low blood pressure, hypothermia, poor metabolism, poor blood flow, and vasodilation.If you want to treat Parkinson's disease, first take measures to change Parkinson's disease, which is dominated by the parasympathetic nervous system, to dominated by the sympathetic nervous system. It is thought that improvement can be expected by taking these steps.

I bought Yuzu Miso Senbei, which I don't usually buy! ! Let's live a life with quality of life in mind! ?

Hello. This is Watanabe Tenmei from Seito Medical School Clear File. This time I'm rewriting a medical school, but I'd like to write about how my values ​​have changed recently. This is a rewritten article about a new study method, but even though it's new, it's an article from about 5 years ago, so it's a long time ago now.

At that time, I was focusing on the second hand one line method. I wanted to read a lot of books quickly, so I devised a method of reading a line before the second hand of the clock clicked. If you try to read one line in one second, you won't be able to read it out loud if you read it out loud, so you can read it at a glance.

Does reading it out loud make it stick in your memory, or does it stick in your memory just by glancing at it without saying it out loud? I think it was a challenging attempt for me.

Another method I recommend besides the second hand one line method is to pretend to be the character. It was a challenge for me to become a character in a novel and empathize with them, allowing me to have various simulated experiences and deepen my humanity.

The second hand one line method and the empathetic method cannot be expected to be effective because the second hand one line method will not remain in your memory unless you are skilled at it, and the empathetic method is mainly a method that can be used for reading stories such as novels and can be used in real life. I think it's a method.

Currently, the study methods that I think are most effective are to simply write things down on paper, and to read the text slowly while tracing it with your finger. Of course, the second hand one-line method is a method from 5 years ago, so in 5 years' time, we may have come up with a method that is even more advanced than the method of tracing sentences with your finger.

So far it's good. So to speak, it was a planned arrangement, and I just wrote what I had decided to write in advance. Now comes the main point. From here you can see two guardian dogs sitting and waiting in front of the gate on either side. It's a boss battle. Please be careful.

If I have free time each day, I would like to devote the first six hours to research. Medical research is currently at its peak, and I would like to reach the perfect point in medical research within 6 hours.

In the next few hours, I'd like to write a rewrite article and then summarize the research I've done just before as a medical report. Now, if I have free time in a day, I can write two articles.

Additionally, the rest of the time is free time and you can read your favorite books. Basically, I read light and easy books such as novels, magazines, and business books during this time.

I haven't bought magazines for a long time. However, yesterday I decided to buy a magazine aimed at older women. The magazine came with a bonus pouch, but at first I laughed and thought it was a toy.

Do women buy magazines because they want a toy pouch like this? However, the magazine costs around 1,500 yen, and when she got home and took out the pouch, I was impressed.

What moved me was that it was a 1,500 yen pouch that came with a magazine as a bonus, and I realized that it was probably made in Japan and was made of decent materials. If 500 yen out of 1500 yen is for magazines, 1000 yen will be the income from this pouch. Question marks lined my mind: How much did this pouch cost and how did they make a profit?

It was an attempt that I planned to buy something that I wouldn't normally buy within my living expenses without thinking about it, but I was moved by the book, a magazine that I don't usually buy, and the bonus that I didn't expect at all. I did it. This feeling cannot possibly be conveyed in words.

By the way, I don't usually buy senbei, but this time I bought a slightly expensive senbei along with the magazine. The flavor was yuzu miso, so it was delicious, but when I took a bite later, I realized that the sugar content was also amazing.

So, in the end, what I wanted to say is that every day I had free time, I spent the entire day studying and researching. And a blog. So, from now on, instead of doing it all day, I decided to make it a half day and use the remaining half day as free time.

Do things you wouldn't normally do, buy things you wouldn't normally buy, and eat things you wouldn't normally eat. I also have a desire to get married, but I don't think I'll get married until I'm in my 40s. In my 30s, I want to enjoy life by doing what I like.

It's good to live a life where you just study and research as a hobby, but I want to improve my life satisfaction by reading novels and magazines instead of just reading hard books. The challenge for people in their 30s is to improve their quality of life. My values ​​are probably new to people in their 50s and 60s today.

In the past, people who didn't get married and did what they wanted as much as they wanted were considered to be picky. However, nowadays there are many people like me, and in fact, it can be said that people like me are relatively common. You only live once. I think it's somehow uninteresting to live a normal life like a normal person, focusing only on staying on the track that has been laid out for you.

This is a matter of my values, but when I look back on my life, I want to live a life with no regrets. Nowadays, there are many places to meet people, such as matching apps. You can live an original life without forcing yourself to fit into a normal framework.

So, how was the boss battle? I think I was able to easily defeat the boss character without getting stuck in the quagmire of a long battle. It was a common sense boss battle, so to speak. This time it's a good break, so I'll stop here, but if I do something different, I'll let you know. Let's go to CM! ! I wish you good luck. See you soon. .

When parasympathetic nerves are dominant, metabolism is suppressed! ! But why are there so many skinny people?

autonomic nervous disorder

The autonomic nervous system includes the sympathetic nervous system and the parasympathetic nervous system.

Sympathetic nerve dominance causes hypertension, hyperthermia, vasoconstriction, and high heart rate, while parasympathetic nerve dominance causes hypotension, hypothermia, vasodilation, and low heart rate.

Also, high blood pressure is caused by too much oxygen, and low blood pressure is caused by lack of oxygen.

(?) What kind of relationship do total cholesterol and triglycerides have with blood pressure?

Metabolic syndrome is a condition in which visceral fat obesity leads to lipid abnormalities, hyperglycemia, and hypertension. Metabolic syndrome is a major factor in all diseases, and the sympathetic nervous system is activated. In other words, the sympathetic nervous system is dominant.

(Assignment 1) Completely check the whole body in home medicine

When parasympathetic nerves become dominant, metabolism is not stimulated.

Will people become obese if their metabolism is not stimulated? Promoting metabolism is a factor in weight loss

(?) If there is a relationship between the sympathetic nervous system and metabolic syndrome, why do people with predominance of the parasympathetic nervous system become thinner? Are there any factors that can help you lose weight more than not stimulating your metabolism?

Drink coffee as a wake-up drink! ? The power of coffee to wake you up refreshed! !

Hello. This is Watanabe Tenmei from Seito Medical School Clear File.

This time, it's a rewritten article, so it's about the story of ``Watanabe taking a break.'' Speaking of taking a break, Golden Week is over, but Watanabe is said to be starting up soon.

Well, I haven't posted anything on my blog for almost a week, and I'm afraid I'll get some harsh words saying that I've lost motivation. I spent this golden week sleeping.

I slept for almost 12 hours every day, and I got to the point where I knew if I didn't start getting better, Tendou-sama wouldn't forgive me.

Fortunately, I went to bed at 5am today and am currently waking up at 12pm. After all, it is essential to have an alarm when going to bed, and some people give advice that if you don't set an alarm, you can wake up in a shorter time, but this is a serious problem and a trap that leads to the inevitable lateness.

I set up my coffee when I wake up in the morning. Place your alarm a little further away from your bed and set your coffee pot next to your clock.

Then, you have to get out of bed and walk around to turn off the alarm, and if you drink a big cup of coffee while turning off the alarm, there is a high probability that even if you fall asleep again, it will be 30 minutes later. has bright eyes.

It's a naive move, but Watanabe's long track record has led him to do so, and it's a rule of thumb to never step into a kotatsu with the power on. Lately, I've been sleeping under a kotatsu every night, and the kotatsu with the power cord plugged in makes me feel sleepy, and the coffee I drink resets my sleepiness.

I would like you to check carefully, but after visually checking that the power is not on and the power cord is unplugged, you can put a comforter etc. in the kotatsu to keep it warm and make it possible to wake up with a cup of coffee. is.

I woke up today after about 6 hours of sleep, but perhaps 6 or 7 hours of sleep is best for humans. The impossible game of getting 4 hours of sleep twice a day, which was advanced to Watanabe, has been devised and abandoned. Anyway, I slept for 12 hours too much, so I would like to get out of the Golden Week schedule.

I want to make a schedule for what time to do this after I wake up so I can have a lean day. In fact, it may be a good thing that there is a little bit of waste in your heart.

What will Watanabe do now? I would like to buy just one can of juice from the vending machine at the front. Canned juice is also a luxury item. Even a 350ml can costs about 140 yen, and a 500ml plastic bottle can be bought for about 80 yen at a supermarket.

Above all, canned coffee and stick coffee cost about 20 to 30 yen each.

Lately, I've been living on the edge of just spending 1,000 yen a day on food alone. I live alone, so I can spend about 1,500 yen a day, but with the recent rise in prices, I try not to go to convenience stores as much as possible.

This time I would like to talk about my current lifestyle.The lifestyle of working until 5am, sleeping until 12pm, and then going back to work suits my personality.

Is it flextime with telework? Some people may have this question, but Watanabe is the Hero of Light who works 12 hours when he intended to work 16 hours. He went around calling himself a villain at one point, but since he's willing to work 12 hours a day, he doesn't mind being given the title of hero. Sho.

Perhaps it is our instinct to want to justify ourselves, whether it is right or wrong.

That's all for now. Watanabe goes off the rails in a big way. Some may say that this gives the story a richness and mellowness, but Watanabe's motto is to tell his story at his own pace, when he wants to, and as much as he wants.

Golden Week, where he slept for 12 hours a day, comes to an end today, and Watanabe will return to hard work. I believe that readers will continue to work alongside Watanabe.

Watanabe may upload videos on this blog in the future, so please watch them if you like. I would like to sequentially distribute information that I think will be useful while watching. Web video! ! It's a trend of the times.

Now, let's review this article. If you sleep under a kotatsu, you should not turn on the power. You won't be able to wake up. On top of that, leave your alarm far away from your bed and have your coffee on standby. I'm sure you'll wake up happy in the morning.

Good night, today is just the beginning. See you soon. .

I wonder if I, who live between the virtual world and the real world, can see the light! ? (1)

This story is fiction.

Let's start by introducing myself. After graduating from university, I got a job at the company where I had worked part-time during my university days. It was a so-called semi-governmental, semi-private company, and their duties included creating reports on economic activities for official business at the request of their superiors. This is a thing of the past now, but the US government was left with no solution to the slump in land prices in the US due to the bankruptcy of Lehman Brothers in 2008. So, although I was a second-rate university student, my grades were at the top of my class, so they decided to go with me. Looking back, at the time I was busy with my studies and training, and I didn't even have a girlfriend, but my first step was a consulting question in a university lecture about whether it was the automobile industry or the Indian economy. So, to summarize, I proposed the following challenge: Toyota Motor Corporation was on the high-end route, and Toyota cars were sold at prices that were difficult for Indian citizens to afford, so Tata Motors, a regional company that was emerging at the time and competed with simple functions and low prices, was selected. I argued that if we consciously marketed Toyota's high-quality, low-priced automobiles, they would sell well. From there, things got strange, and I fell into the illusion that I was being watched by the government. I was studying hard and had very few friends, so I ended up getting addicted to online bulletin boards. My journey to becoming a core member of an organization or group starts with becoming friends with unpopular, low-key people. At the time, with online bulletin boards, the government could have monitored my online movements if the bulletin board operating site had disclosed my IP address. As I started from the corner and worked my way towards the center, my statements became more extreme. It seems that the government probably mistook me for a Chinese spy or something, and decided to continue monitoring me. How did I know I was being watched? It all started when I spoke to the TV. There may be some people who have a habit of saying things to themselves while watching TV, but I was no exception to this, and I turned to the TV and said, ``Areya koreya.'' At first I was skeptical, but TV personalities started responding to my comments. It was still the 2000s. If I had been wiretapped, I would have had to directly communicate my story to the TV cast, which I was sure would be unrealistic. From this moment on, I have been living in a limbo where I don't know whether it is reality or delusion. At first, I thought it was just my imagination. However, the timing was too good to think it was just my imagination. Here, we return to the story of the Lehman Shock. At the time, I was living with my family at home. Even though I feel lonely, my family is with me. On top of that, I continued to have a conversation with the TV. Land prices in the United States plummeted due to the Lehman Shock, and no American economist has an answer to that question. That's when I decided on Beginner's Luck. At that time, I was interested in rich people. I had just read the famous book ``Rich Dad, Poor Dad'' and thought about real estate. What was the Lehman Shock in the first place? The cause was that poor people were borrowing money at extremely high interest rates to own new homes, and speculators divided up the loans and bought them. In other words, the poor people were unable to repay their debts because the interest rates were so high that they were stuck in debt. As a result, large amounts of land and houses were sold in an attempt to repay the loans by selling the houses they owned, causing real estate prices to plummet. Unexpectedly, one year after the bankruptcy of Lehman Brothers, I was approached and asked if I would be willing to come up with a solution. Therefore, I applied the idea from ``Rich Dad, Poor Dad'' and commented that land and houses are assets and should be rented out. If they could repay the loan with the income from the land or house, they might be able to repay the loan while still owning their property. Or, I answered, wealthy people could buy real estate sold by poor people and rent it out. At that time, a new type of real estate investment was born that caused a stir in society for the next several years. That's what the experts said. Better yet, they could borrow money by using the real estate they owned as collateral from a bank and then repay the loan with rental income. I got my first beginner's luck here. In an instant, he solved a problem that the most intelligent American economists had been unable to solve. My virtual world life begins from there. The Japanese government will tell me later, but it seems that I was under surveillance for a year before I was supposed to solve this problem, and I was left alone without complaining. Even if you are a new employee, no matter how good your results are later on, it doesn't mean you're amazing in your first year. There are probably many working adults who receive some hints and make great strides, even if they receive only rock-bottom evaluations in the first year. For example, I sometimes read books about people who had an ace in the sales department in the same department, and if they imitated what they saw, they would get top grades. The first year is a trial period, so you can hit rock bottom there and make a leap forward by adding new ideas in the second year. I'm a visual person, so the first thing I do is read all the materials provided at the company. This is because the materials kept there are always related to the company's work and are some of the most important materials. Well, what happened to me after that? If the first stage was the United States, which was hit by the Lehman Shock, the next stage was Europe, which was suffering from the Greek crisis. I now realize that Europe has come a long way. Just as I divide my life into the first, second, third, and fourth generations, the first generation spanned a little over two years from mid-2009 to the end of 2011. I worked hard during that time. I spent my days talking through the TV, and I was able to interact with a variety of people. I sleep 3 hours and work 16 hours a day, seven days a week. At first, I too was a mere bastard in the virtual world, a world that could be both reality and delusion. The first two years were two years in which I didn't leave any records, and I regret that if I had left any records, some of them would have survived. In this early period, yes. Also includes March 11, 2011. The two years of my first year there were filled with events such as the Lehman shock, the European debt crisis, and the Great East Japan Earthquake. Let's talk about the European debt crisis another day. See you soon.

Be the person who makes the rules! ? Many of my rules shape us!

Hello. This is Watanabe Tenmei from Seito Medical School Clear File.

This article is about creating rules. Speaking of rules, my rule to wake up at 5 a.m. and write two blog articles can also be considered a rule. I make a number of rules for myself.

I drink 2 cups of coffee a day because it contains caffeine, and I drink 1000ml of milk a day. The most important thing when creating a personal rule is that it is something that can be continued for a long time and is effective.

The accumulation of personal rules shapes a person's daily life. When we say we always eat the same food, we can say that we want to maintain a healthy status quo by following our own rules.

In other words, habits are a form of rules, and if they are truly effective, you may be able to see great results if you continue to follow them.

Speaking of rules, I've been struggling with introducing mathematical assumptions into something that I haven't been able to do lately. I view mathematics as a science of assumptions, and I believe that the more assumptions you make, the more the laws of mathematics will change.

Even if the formula is simple, by introducing innovative rules, you may find a very efficient calculation method.

I want to create new ways of thinking from elementary mathematics, the mathematics learned in elementary school and mathematics learned in junior high school. Of course, I would like to cover high school level mathematics and even university level mathematics as part of my knowledge, but if I want more people to understand the laws of numbers, I would like to study simple mathematics. I think more people will appreciate it.

I have always thought that the future of science is in jeopardy unless we make knowledge simple enough for the general public to understand, rather than having difficult subjects become the preserve of a few elite elites.

There are theories that only a handful of people understand and theories that are easy to understand that anyone can understand, and of course there is a difference in whether they are valid or not, but which theory is more popular because more people understand its value? There is no doubt that it is an easy theory that anyone can understand.

It seems that there are often difficult papers that even famous mathematicians, let alone ordinary people, who take on difficult mathematical problems throw away their papers, but no matter how difficult the paper is, there are only a few people in the world who will appreciate it. If so, then that paper is equivalent to abandoning its own value.

By creating simple rules and fleshing them out in a simple manner, theory can be widely applied and become the foundation for creating new values. I myself am involved in mathematics research and spend my days struggling to come up with groundbreaking assumptions.

There are many rules in society as well. Laws are the best example; the world is shaped by each and every rule. When rules are created within an organization, it can be said that the people who create the rules are in charge of the organization.

If rules don't fit together, it will create a contradiction, so as you add rules one by one, it becomes important to have a sense of balance with other rules.

As a personal rule for myself, I would like to wake up every morning at 5 a.m. and immediately write two articles. ``Be the person who makes the rules!'' There's no doubt about it.

If we're talking about mathematics, the results of changing the rules will immediately appear as calculation results. Find assumptions in mathematics. Throughout the thousands of years of mathematics history, many mathematicians have emphasized changing assumptions. However, there may not be that many mathematicians who have made the assumptions they want.

My future challenge is to acquire the ability to continuously generate new mathematical assumptions. Based on that, I would like to upload the research results to this blog. It may be a long and thorny road, but we will do our best to meet your expectations. that's all. See you soon.　

Let's learn with the English version of Wikipedia! ! The problem with Japanese textbooks is that they are difficult to understand! ?

Hello. This is Watanabe Tenmei from Seito Medical School Clear File.

What does science mean to us? Is it an iron-clad castle that towers far into the sky, or is it a means to make society more prosperous and comfortable?

I think that if someone has been self-taught for a long time, there is a high possibility that they have experienced a blank period and a slump. If you come across a high wall that you cannot understand, you may take a temporary break or give up.

I want to say Trial and error is good when you're in a slump, but once you study a different field, that is, tackle a new subject, you'll be more likely to produce results than if you continue with the subject you're in a slump on.

Of course, after you've dabbled in other fields to some extent, it might be a good idea to tackle the original problem that caused you to fall into a slump. When you hit a wall during your long life of self-study, it may be better to simply look for another route instead of trying to break down the wall and get over it.

In my case, I have been working on university-level and graduate-level subjects these days, using university-level groups, rings, and fields as an introduction to mathematics content. When I started studying the introductory section, I had a vague feeling that it would take a lot of patience and time to understand these technical terms using only Japanese textbooks.

So, I bought other reference books and tried to do the calculations on my own without asking anyone. The result is a technical term called Lie algebra, but I was completely exhausted just looking up specific examples.

Then, I realized something. The question is, do you learn about difficult content on foreign language sites as well as on Japanese sites? In particular, since America is the home of learning, I felt that it would be more efficient to read materials in a foreign language. Of course, I don't want to lower the quality of Japanese textbooks.

However, I had a suspicion that Japanese researchers were rewriting textbooks written by overseas researchers in a way that was difficult to understand. Therefore, I compared the Japanese version of the wiki and the English version of the site. Below, quoting:

`` A group in mathematics is a group that has associativity and an identity element and an inverse element when a binary operation and its target set are viewed together. Groups are considered to be one of the fundamental algebraic structures , providing a basic framework for various constructions in mathematics and physics in general. Groups are themselves objects of study, and the field is called group theory . ” (wiki quote: Group (mathematics))

“In mathematics , a group is a set with an operation that satisfies the following constraints: the operation is associative and has an identity element , and every element of the set has an inverse element .” (wiki:group)

how is it. The Japanese quotation above and the English quotation below are not the same sentences, but they have very similar meanings, and those who understand basic English words can read the English sentences below from simple junior high school level English. You can see that it's done.

If you are reasonably confident in your English, try searching for "group mathematics wiki." When you read it, there are links to the technical terms in blue, so if you don't understand them, I recommend you to jump to the links.

Even if you don't understand something in a textbook that is famously known as a classic in Japan, if you look it up on the Japanese version of the wiki, it will be difficult to understand and the average person will run away after reading it for 10 seconds, but if you look it up on the English version of the wiki, you will find it difficult to understand. I think the quality is good because there are a lot of users, and there is a lot of information.

To be honest, I've heard that self-study can only get you to a certain level, and that you need a master to go beyond that.

If I had tried to continue studying and researching only in Japanese, I would have probably hit a wall at some point.

One way to avoid this situation is to make full use of English version wikis and calculation tools that are written in a universal language like English, and the day will come when you will be able to read difficult mathematical papers that I cannot easily complete. Probably.

I wish you good luck. See you soon.
