Every year at my birthday, I have to cook fishes I get from net.

I think that that is

An unreasonable event

that I am enforced

Well, the fishes are fresh and good, so the taste become better, even if I cook as an amateur.

If I sliver fish smoothly, I think it is cool, but it is impossible that the skill becomes well.

-----

I was given the birthday presents from my family, they become to know my favorite.

When I opened the fancy lapping, there were

Screwdriver set, from the junior daughter,

Tangerine 3kg, from the senior daughter,

Persimmon 2kg, from my wife.

On the tangerine, each difference face are drew courteously, so I said,

"Great! It looks like very hard for you to draw faces on all the tangerines.

When I applauded her,

She started to draw faces (only eyes) on other tangerines suddenly picking up them at the bottom of bag.

(Continuation from yesterday)

I propose that you might have to go fifty-fifty with both friend-supremacist and loneliness-supremacist.

"Doing by halves" is important for anything. It is a sort of portfolio that is a standard way to avoid risks.

When younger run to extremes, something wrong happens in many cases.

When I talk like the story, I always start to tell about "Japan Red Army" and "Aum Shinrikyo". But I want to avoid the direction today.

-----

In fact, this is everyday issue.

In conclusion, "friend-supremacist" are going to come of age with

"annoying",

who want to understand others perfectly and don't accept the situation that the others cannot understand him/her.

This type of persons is going to cry, shout and get angry with everything that they don't go their own way. They are annoying me beyond my imagination.

Concretely, they have an absolute value for domestic festival, class reunion, and alumni association, and to make matter worse, they believe that others think same.

For example, they cannot understand my negative intentions as follows,

"I have no plan to commit you in my life"

"Please don't contact me, when I have rejected the attendance three times consecutively"

(Continuation from yesterday)

Recently, I went to a medical checkup and I achieved new record of light weight in my life.

(Later, I will tell you the story that the doctor discussed this success critically with saying "what are you doing?")

Today, I am going to tell you the another story. This time, my vision, which was about "0.7" at the last time became "1.5" of both eyes.

-----

Of course, my recent, a decrease in visual acuity became terrible and I know well that this "1.5" is the wrong measurement result (no doubt).

Needless to say, I don't claim my own guilt (?), like "No way! I request re-measurement!!"

Recently, the vision inspection has also been automated.

The procedure of the machine is that I peek the scope of the machine, "the arc" appears, and I manipulate its direction at hand of the stick.

Before measurement, I was told that "when it is no longer visible, please press this white button,"

Who "declares with my "invisible"? "

Even if I cannot do it, I am going to try to watch the up, down, left and right in the "mind's eye". It is "spirit of the subject".

(To be continued)

Now I am in hospital for medical checkup.

This monring, my weight was the target weight accurately .

In this series, I state a hypothesis,

- Human beings are a kind of control system,

- So, human's weight control is possible perfectly,

and, continued to write the essay about diet.

I think, the hypothesis testing have done well for the third consecutive year.

-----

However,

My diet formula shows, in my case,

- the limitation of loss weight is 2kg in a month

I have to make an efforts to keep my weight within 2kg from the target

Especially, it was very hard for me in last month.

In addition, in a few days, I could not feel pain at all, and I think I have a risky condition.

All are assumable in my mind.

-----

However, the diet that only lose weight seems not to "contribute to health" so much.

Since I was told by the person who performed the echo diagnosis, "Oh, it's just metabolic," "There is a shadow in the liver."

To tell you the truth, I thought that

"you should measure me silently. because the inquiry is received from the doctor"

(Continuation from yesterday)

8-bit microcomputer (early computer) was born when I was about 12 years old. Let's provisionally set this as 1975.

And Windows 95 came out in 1995, 20 years later.

For 20 years from 1975 to 1995, I have to admit that the personal computer was not a general purpose product(It was a time when I was persecuted as a nerd just by using a personal computer.)

However, after Windows 95, it can be said that the personal computer has become a general-purpose home appliance.

Furthermore, mail was confirmed as a tool equivalent to telephone by mobile phone,

Let's look at a considerable margin and let that time be 2005, after ten years.

-----

From the above, the following hypotheses can be derived.

Hypothesis 1: "In the year 2005, mail was established as a means of communicating with the citizens"

Based on this hypothesis, I will continue the verification.

At the year 2005, I suppose that the maximum age limit for people working in active service is 55 years old.

Thinking that the persons who was younger than this age at that time, had an environment that they could use mail". And additionally I can derive the following hypothesis.

Hypothesis 2: "At the present time, a 70-year old person should be able to use e-mail as a means of daily communication with their margin"

In the above hypothesis 2, there are a lot of examples in my relatives that can prove this (they can use use of e-mail everyday). Of course, there are also many counter examples, too).

From the above, my "theory" is, except for physical problem due to aging

"At the present time, it is not permissible for elder people around 70 to use "older" as an excuse for not being able to use e-mails."

-----

Of course, this is quite a rough "theory".

This might be a violence itself.

So, I do not want to generalize this "theory".

However, I think that we can impose this theory on some specified people.

For example, they are leaders of an organization.

_ -----

It cannot be helped that they are blamed for their inexecution as "idleness" and "irresponsibility". It is "No room of the pity".

At least, people of the generation of mine, can use "mail" "conference call" and "file sharing" on a routine basis.

All people who don't do "prior announcement", "frequent occurrence" and rob me of time for my private activities,

and don't do "any approach" "any effort" and "any alternate" with an excuse of "old age", and come to put me "inefficiency"

are my enemies.

(To be continued)

(Continuation from yesterday)

I have one question.

Nobody knows that I stop the system.

Nobody in the world can confirm it .

It may be that "I didn't stop it".

That means,

"What is the difference of my claims between "I stop the system" and "I don't watch the picture"?"

These two claims are not treated as the same.

However I also don't feel so unpleasant for her opinions.

"Why I did so ?"

-----

What I came up is Article 29, Paragraph 1, Item 2 (*) of the Patent Law.

(*) "Public implementation" in the same item means that the invention is implemented in a situation where an unspecified number of people can know the content of the invention.

The claim "I will not watch" is that "I can't say "I can't watch". (although it's a little confusing).

On the other hand, the claim "I stop the system" is "I can say "I can't watch"".

In other words, for the same person (although there is a difference in reliability), the trustworthiness changes depending on the contents to be implemented.

Let me see, the analogy of thinking is similar to the story of Bayes' posterior probability (my favorite).

(To be continued)

"Silent Artificial Intelligence - Why was not AI used to predict US presidential election ?"

I'm rereading it.

"It's been four years since then"

I am impressed by the speed of time, "fast".

-----

By the way, I don't think anyone has pointed this out yet. However, I'm worried about

"Civil War in the United States"

-----

Here's an example of a scenario.

(Step 1) Candidate Trump wins the direct ballot, but the results of the subsequent mail-in ballot upset candidate Biden.

(Step 2) Candidate Trump declares the mail-in ballot invalid by presidential decree and unilaterally issues a victory declaration.

(Step 3) California (the Democratic state) is the first to declare its independence, and Texas (the Republican state) follows suit.

(Step 4) Each state places the National Guard on the border. Each state governor announces entry into the State of California or the State of Texas.

(Step 5) Candidate Trump mentions the use of limited nuclear weapons (nuclear weapons with limited power (?)) in the United States, and in the worst case, he uses it.

So, if China and Russia back up the above two major states, it will absolutely be the last world war for humankind.

-----

Four years ago, I couldn't even think like this.

-----

My wish now is that I don't care who wins the presidential election, however,

"I'd like to see an overwhelming majority to win or lose."

That's just it.

Today, new my column is released, so I take a day off.

Let's turn the world by "Number"(68) Extra:

Seven Questions to follow the "Corona Vaccine Refuser"

-----

Today, I would like to share with you an e-mail from Ms. M, who is in charge of editing my column, with her permission.

====== From here ======

Mr. Ebata.

Thank you for your confirmation. The article will be published at 11:30.

Yes, this column was long, but it was interesting.

After reading your co-worker's review, I added a note under the table of contents on the first page, "If you don't have time, just read the Shibata Report.

I read your second daughter's review and thought for a moment, in a strange way, that there must be a large number of people who do not have enough fear.

At one time, there was a lot of talk on the news about "fearing Corona correctly," but I think that Japanese people, for whom the number of deaths is quite small, probably cannot feel the reality of a situation in which "more and more people are dying by Corona".

It's not like Italy, where the dead are being trucked in by the truckload, or like New York, where cremation can't be done in time and a lot of bodies are stored in a huge warehouse next to the hospital. The number of infected people has increased rapidly, however, many young people may be wondering, "Is corona really that scary?

The other thing may be that it's hard to imagine how painful and frightening the COVID-19 can be.

In my opinion, I just read this "Appendix 1" and said, "Heee! I really, really don't want to get infected! I'm so scared....

If this had been a pandemic of an infectious disease with a high fatality rate like SARS or a horrible death rate like Ebola, where people bleed to death from holes in the ground, I wonder if people would have taken a completely different approach to refraining from going out and getting vaccinated.

I don't have any friends or acquaintances who are college students. However I would like to ask them, "To be frank, is Corona scary? , if possible,

It's a long story (no need to reply), but I hope you will let Dr. Shibata know how much I appreciate his help.

I'm looking forward to working with you two.

====== To here ======

Conclusion: Just be sure to read "Appendix 1" of this column. Especially for parents with children under the age of 12.

I have written before about wanting a lightweight desktop PC that I can carry around with me.

I bought it.

It was a really, really painful expense, but I was afraid to use a free-address computer for security reasons, and I was determined to make it an unavoidable expense in order to do "serious coding" with a free-address from now on.

Having said that, if I was going to spend money, I wanted it to be something other than PC.

If I count Raspberry Pi as a PC, then I have almost 10 PCs in our house.

-----

A PC is a "raw product" and will be useless after three years.

For example, in yesterday's seminar, the laptop I brought as a backup for my iPad was completely useless, and I almost ruined the presentation I had prepared.

But of course, if I keep using the old OS and apps, I can use them for even 100 years.

But if I install Office, Teams, VSCode, R, Docker, SAI, and so on, my PC will naturally become unusable.

-----

"As long as I can write in my laptop's editor, that's all that matters"

In this world, I would not have to manage 10 computers.

I want to put figures and tables in that text, I want to do calculations, I want to do simulations, I want to use a million objects, I want to--

That's what I want, and that's why the PC 'rots' every year.

I skipped the first 3/4 of the NHK program "Mathematics without Laughter: Imaginary Numbers" and watched it from the point where imaginary numbers are explained.

'Hmmm, I am afraid that's the explanation after all.'

I was a little disappointed.

No, of course, it is "very good" as a program.

However, I think it may be a bit harsh to offer the "Schrodinger equation" as an explanation of how imaginary numbers have entered our lives.

For example, if I were to ask myself if I could get my daughters or my wife to understand the Schrodinger equation using the following board, I would think, 'Well, that would be impossible.

It seems futile to say, "It's just like the equation of motion for a spring."

-----

I wonder if it could be explained in terms of 'imaginary numbers are a handy tool.

Isn't it impressive that we can express the quadrature operations of multiple trigonometric functions with different phases and frequencies using only "i" expressions?

Not? No-no.

I use it crudely to say, "Whenever I am at a loss for a calculation, I just try to apply them to Euler's formula.

-----

My recommendation is "An imaginary number is a 90-degree rotation," described here.

And so, the second half of this description (the conversation with the second daughter) is an example of the appearance of imaginary numbers in the real world.

-----

I hope that "imaginary numbers are a useful tool to be used and put to good use" will become widespread.

However, since our country is so irregular in devising the "no trigonometric function needed" theory, I feel that it will not work for the next 100 years (or even 100 years from now).
