Looking at distant scenery or looking at a computer from a distance improves your eyesight and aligns your eyes. by Nada 20231110

Hello. This is Nada from Seito Medical School. This time it may just be my imagination, so please try it yourself. You may have heard the old legend that seeing far away improves your eyesight. For example, people on the ground seen from the top of a skyscraper or a distant mountain seen from a window. I used to think that my poor eyesight was something I was born with. Therefore, the bad eyesight was alleviated by wearing glasses. However, it turns out that like IQ, vision is acquired, that is, it improves after birth. In fact, the aforementioned legend that visual acuity improves when you see far away means that visual acuity is changing independently of genes.

The main cause of poor eyesight is probably a lack of focus, but it can be said that focusing can be done by looking into the distance. However, if you simply look at mountains in the distance, it seems that there is no productivity other than improving your eyesight, so I think it would be a good idea to start by reading books.

Gradually move the distance from which you hold the book further away, and read the book closely so that you can see the letters in the distance. By concentrating on the text you are reading, your eyesight will gradually improve. Next, if you are using a computer or reading a newspaper, by looking at these objects from a distance with the naked eye, you will be able to focus on distant objects, and your eyesight will gradually improve.

It is likely that the position of the eyes will also move to a more regular position. As a side effect, your eyes may improve and you may become a handsome or beautiful woman. I also have astigmatism in only one eye, but the astigmatism may also be due to a problem with the position of the eye, and the lens may be out of focus because it is misaligned from its correct position. This is just my assumption, but it has been said for a long time that seeing far away improves your eyesight, and it would be a waste to treat that as a superstition. That's all for now. See you soon.

Are your past self and present self the same person? Deja vu is finding commonalities between your past self and your present self. by Nada 20231110

Hello. This is Nada from Seito Medical School. I have always felt a sense of déjà vu. In Japanese, it can be translated as déjà vu, but déjà vu is the feeling that you have seen the same scenery before, even though it is new to you. Or, even though it's your first time doing something, you can use it to say that you've had the same experience somewhere before. Perhaps you feel that way because there is a part of you that overlaps with an old memory that has sunk deep into your memory, and your intuition determines that you have already experienced it.

Even if I change my appearance or shape, there are many things that are essentially the same, and I come across similar scenery in many different places than I expected, so I can interpret this as feeling like déjà vu. It was written in some material that there seems to be a concept of treating your past self and your current self as different people. Also, I'll do my own research on this, but I think déjà vu is actually the opposite, finding commonalities between your past self and your present self. Of course, the further apart the past and present are in time, the more difficult it is to realize the same situation, so we can say that we are talking about time differences that allow us to identify with our past selves. Feeling déjà vu may be more likely to occur when the situation is characteristically the same, and when intuition is superior, that is, when intuition is superior to reason.

For the past few years, I've been experiencing a sense of deja vu wherever I go, and it's really just stopped for the past few months. The last two or three years have been a roller coaster of my life, and up until now I had been thinking and acting logically, but now I have learned to act as I see and feel intuitively. It has changed to When I lived with reason and logic, I was bound by common sense like other people, but when I lived intuitively, I felt like I was walking a tightrope on a bicycle, or walking along a precipice. However, when I act according to my intuition, I often end up reaching the ceiling. I'm also careful not to break the law just because I think intuitively, but I've realized that the easiest way to live is to rely on intuition and use reason as an aid. Of course, there are hurdles to overcome, and the key is how far you can believe in yourself. Furthermore, it will no longer be like living a so-called normal life.

However, if you want to be able to make good decisions that can be called lucky, try the Fast Chess Theory. When a chess player looks at the board, he can instantly predict the next move, but even after thinking about it for a long time, he can't seem to come up with a better move. First Penguin, First Chess. Everyone, please listen to the voice of your intuition. It should be safe for everyone to use intuition as an aid to reason. Have a nice day today. See you soon.

Read the textbook starting from the parts that interest you. Then teach what you learned to someone online! by Nada 20231108

Hello. This is Nada from Seito Medical School. When reading a textbook or reference book, do you read it in order from beginning to end? I recommend reading the textbook starting from the parts that interest you. If you look at the first table of contents, it should give you a rough idea of ​​what's on each page. I think that the order in which you read a book doesn't matter as long as you end up looking through all the pages. Follow your own curiosity. Textbooks and reference books that you must have picked up because you were at least interested in them. If you prioritize what you are most interested in, you will be able to absorb knowledge more efficiently.

Or, if you have a purpose in mind at the beginning, such as wanting to research something, you will be able to enjoy your time more deeply. What do you want to research and what do you want to know? Students at universities that are research institutions definitely need to be aware of these issues. Of course, I think it's worth being aware of for junior high and high school students as well.

Read books in a way that immerses you in line with your own intellectual curiosity. That's the fastest way to acquire knowledge. If you teach others, which is said to be the most effective way to learn, your retention of knowledge will be much higher. I also like to write down whatever comes to mind at the beginning of the day, even if it's just like prose. What do you want to learn in the process, and what kind of schedule will you use to accomplish it? I think it's best to first understand the overall picture to some extent, and then narrow down your focus and learn from there. The theme this time was that the most efficient way to learn knowledge is to read from the parts that interest you, without worrying about the order in which you read them. See you soon.

Are religion and economic activity superficially opposite, but essentially the same? Let's hear from some amazing people!

Hello. This is Watanabe Tenmei from the clear file. This time, we will be rewriting the medical school, so we will be talking about ``There is a Living Bible.'' In terms of religion, I would like to rewrite the question, ``Who is a famous monk or a first-class founder?''

There are people in this world who can be considered as bibles. Like the title of the article before the rewrite, is he a famous monk who has thought through his teachings, or a first-rate founder who has devised a formula for success based on his own philosophy? I'm interested in these wonderful people who know all the right answers.

These are people who overcame worries and difficulties to become important people under their own mission. What is the mission here? A mission is something that only you can do, and it can be said to be part of your destiny. If someone were to ask you, ``What is the one challenge that only you can accomplish?'' how would you respond?

I believe that the mission of a famous monk is to serve as a supporter who reaches out to people who live with worries and pain in this world and guides them in a better direction. Even if there were a heaven and hell, monks are professional guides, so they always need to reach out to those on the hell side, and that is their job and mission.

I don't know much about religion either, but when you think of a mission that God or Buddha has given only to you, it leads you to become an extraordinary superhuman, and it gives you more power than if you didn't believe in religion. I think we can make the most of it.

Best of all, it lets you know where you are. What role does my existence play in this universe or world? Religion can be said to play that role. I am by no means recommending any particular religion, but I feel it is my mission to write this blog.

I haven't decided yet whether to monetize this blog or not, but my current ambition is to continue writing this blog until I die, in my 30s. I can say that reading this blog and hearing people who say they have benefited from it is an asset to me. This blog is basically where I post my discoveries and research, but I hope you will continue to use it for many years to come.

When I think about the existence of God and Buddha, I think that the ideas of poverty and interestlessness, which are teachings that can be said to be common in various religions, are essential teachings in order to achieve greater success. As my policy states, if you want something, you will only get a small amount.

On the other hand, isn't business activity the exact opposite of a religion that praises interest-free living? When business owners run a business, sales are important, but profits are also important. Economic activity involves devising business strategies and winning competition in order to earn more profits. This is what economics calls utilitarianism.

There may not be that many managers in society as a whole, but if you count the number of companies, of course, there are many managers. There are two types of business owners: salaried business owners and founding business owners. A salaried manager is a person who started work at a company as a salaried worker and became a manager as he rose through the ranks.

On the other hand, founding managers are entrepreneurs who started their own businesses from scratch and have grown the company together. Even founders and truly outstanding managers often have their own policies and philosophies. For example, Omi merchant's Sampoyoshi is a good example. It means satisfying all stakeholders.

I think managers who started a business with ambition and then grew the company are amazing people. Economic activities may seem to be the exact opposite of religion, but their essence may be surprisingly similar.

For example, as I mentioned above about the interest-free nature of religion, it is necessary for a company to be profitable at least in its economic activities, but if it is managed by squeezing profits as much as possible, if it is a company that is originally profitable, it will sell cheap products with little profit. Many customers may buy the product if they ask for it. This is what is called low profit, high sales.

I think there are different views on whether higher or lower prices are better depending on the type of product. For example, if it's food, the cheaper the better, but if it's too cheap, you'll be worried about where you bought it from. On the other hand, cheap home appliances may have poor performance, so there are many people who request a certain price. I'm worried about the safety of the cheapest home appliances.

However, no matter what kind of product it is, if it is reasonably priced for the customer, it is not a bad idea to pick it up and look at it. In that sense, it seems that the interest-free nature of religion has a lot to do with the low-profit, high-profit nature of economic activities.

Furthermore, in religion, there is the idea of ​​being close to people on the side of hell, which is my personal opinion, but in the sense of making many people happy, there are many activities that change society and sell good products at low prices. You can also think of it as saving people.

There are many ways to practice religion, such as staying in the mountains, meditating, and asking for donations, but these are traditions that have been around for a long time, so I don't criticize them, but many people who work in society I don't think there is anything wrong with working for the sake of one's cause, even if it is part of religious training.

Now, in conclusion, religious teachings and corporate economic activities seem to be very different, but this is only superficial; if you dig deeper into the essential points, you will find that they have many things in common. I can see it. In the article before the rewrite, I said that (my result) divided by 1 could be anything.

In other words, no matter what the result is, if you average it by yourself, it will always be the average value. However, I don't need to compare myself to others, but rather than taking average values ​​in my own world, I think I should look more closely at the people in the society around me.

The article before this rewrite was written around September 2023, so by the current February 2024, it can be said that the way of thinking has changed significantly. I don't know if this is progress or regression, but I think I should have a little more confidence in my ability to write articles like this without comparing myself to others.

There's no need to compare your writing ability with others, but at least I'm neither better nor worse at writing than anyone else. At least it's not the lowest value for humanity. Even if you take it lightly, judging from my blogging history of about two years, I'm still not good enough to get a job, but maybe it's not that bad.

No one will criticize me if I say with confidence that I have writing skills. That's why this time I was rewriting the medical school. In the end, there are people who are amazing in both economic and religious activities. I recommend that you listen to their stories and pay attention to them with an ambition to see how you can get closer to them, or if you can quickly surpass them.

They may surprisingly tell you something that will turn your sense of values ​​upside down. that's all. See you soon.

Disassemble cars and extract natural resources. If we can turn it into a successful business, we could become a resource-rich nation. by Nada 20231108

Hello. This is Nada from Seito Medical School. This time, it's about surplus resources. When you think of natural resources, you probably think of manufacturing materials that come from coal mines, such as ores and rare earths. I think there are many different kinds of resources, but I think natural resources are an important element that is essential for manufacturing. When most people think of rare metals, they probably think of new metals extracted from mines and used as materials for cars and other products.

Here's what I want to say. The question is whether the natural resources really need to be new. If you think about it, there are a variety of second-hand items, from books to games to clothes. However, I have never heard of second-hand products made from natural resources. Of course, recycling aluminum and steel cans is a natural resource for second-hand goods, but... Even if it is a natural resource, if something made from it is thrown away, it becomes garbage that cannot be decomposed naturally. Previously, there was a problem with large amounts of plastic straws being thrown into the ocean, but it takes a lot of effort to dispose of even one car. However, the amount of natural resources that can be extracted from a single car is by no means small.

Cars are exported from wealthy countries to less wealthy countries as used cars, but I don't think many people know what happens to those used cars at the end. I am one of them and don't know what will happen in the end. Therefore, there is a need for a business that specializes in dismantling used cars with specialized equipment. I've heard of the used car dismantling business, so exported used cars may end up being dismantled somewhere. Therefore, if there were a company that specialized in dismantling used cars and extracting natural resources, Japan could become a resource powerhouse even if there were no mines in the country to mine new natural resources.

I think it will be important in the future to be able to recycle resources. The recycling situation itself will have an impact on the global environment for centuries to come. It can be said that this is a very important social issue.

The prime number formula is here! ! axa-bxb-cxc is a 3mod4 prime number formula! ? By the way, axa+bxb is a prime number expression of 1mod4

Hello. This is Watanabe Tenmei from Seito Medical School Clear File. This time, I'm going to talk about prime numbers, and I might have found the formula for prime numbers.

The first expression that comes to mind for prime numbers is the expression a^2+b^2. By the way, a^2 means multiplying a twice, and a^3 means multiplying a three times.

I have long suspected that a^2-b^2-c^2 is a prime number formula. I couldn't say for sure, so I felt confused.

The formula a^2+b^2 yields all 1mod4 prime numbers. However, the prime number of 3mod4 does not come out. By the way, 1mod4 means that the remainder when divided by 4 is 1, and 3mod4 means that the remainder when divided by 4 is 3.

The reason why only 1mod4 comes out is that when you substitute 0, 1, 2, and 3 for a^2, 0^2=0, 1^2=1, 2^2=4, 3^3 =9. If we look at the mod4, or the remainder when divided by 4, we get 0mod4, 1mod4, 0mod4, and 1mod4.

We have looked at numbers 0, 1, 2, and 3 in order, but in the subsequent numbers 4, 5, 6, and 7, their square mod4 is 0, 1, 0, 1. If you mod4 these 4, 5, 6, 7, or any subsequent numbers, they will become 0mod4, 1mod4, 2mod4, or 3mod4, so their squares are 0mod4, 1mod4, 0mod4, and 1mod4, respectively.

Since a^2 mod4 is 0 or 1, a^2+b^2 is either (0+0), (0+1), (1+0), or (1+1). In fact, this is one of 0, 1, or 2, so it will be anything other than 3. By the way, 4 is 0mod4, so 4 and 0 are the same mod4, 0mod4 as a remainder when divided by 4.

In other words, a^2+b^2=3mod4 does not exist. At least for integers.

So, let's change the sign of a^2+b^2. a^2 – b^2 is the product of all composite numbers, that is, the product of multiplication. A prime number is a number that is only divisible by itself, such as 2, 3, 5, and 7, but a composite number can be said to be the product of two or more integers such as 5×3 or 5×7, such as 15 or 35. .

Here, since a^2 – b^2=(a+b)(ab), there are conditions, but all composite numbers will come out. The condition is that when the difference between a and b is 1, a prime number may appear, for example 4^2- 3^2 = 7. If the difference between a and b is 2 or more, and both a and b are integers that are not 0, a composite number will appear.

For example, 5^2 – 3^3 = 16, 7^2 – 2^2 = 45.

Earlier, we reversed the sign of the first equation a^2 + b^2 from + to - as a^2 – b^2, but if we change the sign, we will get the opposite value. For example, if you change 4a+1 to 4a-1, 4a+1=1,5,9,13,17,21,... and 4a-1=3,7,11,15,19,23,... Odd numbers that did not exist in 4a+1 will now appear in 4a-1.

So far, a^2+b^2 includes all prime numbers of 1mod4, and a^2-b^2 includes all composite numbers, although there are conditions. While a^2 – b^2 was a composite number, by reversing its sign, a prime number of 1mod4 appears, which is the opposite of a composite number.

So, even though we inverted the formula for the composite number by changing its sign, why doesn't the formula for the prime number 3mod4 still come out? This is because the sign of b^2 has changed between a^2 – b^2 and a^2 + b^2, but the sign of a^2 has not changed.

If we change the formula for the composite number of a^2 – b^2 to the formula for the prime number of a^2+b^2 which is 1mod4, and then change the sign of a^2, we get -a^2+b^2. , is essentially the same as the formula for a^2-b^2. However, if you change the sign of a^2 and b^2 from + to -, it becomes - a^2 – b^2, which becomes a negative value.

In other words, from the relationship of only a^2 and b^2, there is no prime number of 3mod4.

Then what should we do. Here, let's reverse the expression for a composite number, not by its sign, but by whether it is a prime number or a composite number. a^2 – b^2 Since b^2 is a composite number, let's replace b^2 with a prime number p. a^2- p Now, for this expression to be an odd prime number, a^2 must be 0mod4.

In other words, if you subtract the prime number of 1mod4 or the prime number of 3mod4 from 0mod4, 0mod4-1mod4=3mod4, 0mod4-3mod4=1mod4. By the way, 0mod4-1mod4 is 3mod4, but it is essentially the same as mod4, and when divided by 4, -1mod4=3mod4=7mod4, etc.

Here, we want to obtain a prime number of 3mod4, so by substituting the prime number formula of 1mod4, that is, b^2+c^2, to p of a^2 – p, we obtain a prime number of a^2 – p = 0mod4 – 1mod4 = 3mod4. Masu. The reason why a, b, and c are interchanged is because a^2+b^2 and b^2+c^2 are essentially the same addition of squares. As long as other people can see it and the same alphabets don't overlap, there's no problem in changing it around.

By the way, a^2+b^2 and a^2-b^2 are essentially addition and subtraction, so please be careful about that.

Now, if we substitute b^2+c^2 for p, we get a^2 – (b^2 + c^2). Expanding the formula, we get a^2 – b^2 – c^2, which is the prime number formula mentioned at the beginning. By the way, a^2 must be 0mod4 and a is an even number. b^2+c^2 is essentially the same because the combination of b and c is even and odd or odd and even. In other words, 0mod4+1mod4, so if b^2+c^2 is fixed as an even number and an odd number, a^2 – b^2 – c^2 = even number^2 – even number^2 – odd number^2.

Even numbers can be expressed as 2a and 2b, and odd numbers can be expressed as 2c+1, so it becomes (2a)^2-(2b)^2-(2c+1)^2, which is the prime number expression of 3mod4. Since the prime number expression of 1mod4 is a^2+b^2, we can now express the expression of the prime number of 1mod4 and the prime number of 3mod4, that is, all prime numbers. By the way, let's leave the prime number 2 alone.
