(515) The Sturgeon moon [調べる]

    One of my friends taught me that the August full moon is called the Sturgeon moon. She texted me, "It is very beautiful. Look up the sky now to see the August full moon." I did so and took a picture of the moon. A very bad phot, there was an only white blur spot in the dark sky.

  What is sturgeon? My electronic dictionary says sturgeon is fish whose roe is caviar. Who calls the August full moon "the Sturgeon moon"? I got very interested in the name. Immediately I googled the word and I knew American Indians called twelve full moons of a year by their own special names. I also got cute illustrations of them at a site.

  I have a book published 1997, HOBMOK and Other Writings on Indians, written by Lydia Maria Child. I bought this book around 2004 at a secondhand bookstore in Japan. I knew this book is about American Indians but I stopped at the very beginning of introduction of this book and gave up reading.

Hobomok s.jpg
  Hobomok, A Tale of Early Times is the provocative story of an upper-class white woman who married an Indian chief, has a child, then leaves him―with the child―for another man. This novel, originally published in 1824, is a powerful first among antipatriarchal and antiracist novels in American literature.
  The Sturgeon moon encouraged me to challenge this book again. But this time, first of all, I tried to search for the words of moon from cover to cover. I fortunately found a word of "Sturgeon moon" in the chapter XII. Then I read only this chapter.
The Sturgeon moon
  "Hobomok," interrupted Mr. Conant, who entered at this moment, "it is a pity you were not out with you bow, forasmuch1) as a fine deer just ran through the settlement2)."
  "There's a tribe of 'em, out on the plains3) to night," answered the Indian. "Their tracks4) are thick as flies5) in the Sturgeon moon." Sagamore John's men are coming out with―with―" and unable to think of the English word, he pointed to the candle.
  "Oh, they are coming out by torch-light," exclaimed Mary, "as Hobomok says the western Indians do. How I do wish I could see them hunt by torch-light."
1) forasmuch: in view of the fact that.
2) settlement: a colony, especially in its early stages.
3) plain: a large area of flat land with few trees.
4) track: a mark or a series of marks left by a person, animal, or thing in passing.
5) thick as flies: it's an idiomatic expression, it means "to be very abundant."
In the previous page, there are other Indian moons.
The cold moon
  It was in the middle of the "cold moon", by which name he used to designate January, that he arrived in Salem, on one of his numerous visits, bringing with him some skins of the beautiful grey fox of the Mississippi.
The moon of flowers, the hunting moon
  "One warrior came among us in the moon of flowers, and spread his blanket with us through the hunting moon. I talked with him, like as with the Yengees. He told big stories about his tribe; but he say Great Spirit lay between us, and his back bone so high, make foot of the Indian weary.

(514) A woman of the Long Neck Tribe [調べる]

   Working with the U.N. Human Settlements Programme, the photographer Ruben Salgado Escudero traveled to Burma to showcase the transformative effect of solar energy. One of the nighttime portraits in his photo essayーDaw Mu Nan at her grandson's home in Pa Dan Kho.


  Before I threw away my old TIME magazines, I turned the pages of Nov. 3, 2014 issue. I found this photo of a woman of the Long Neck Tribe in the article, "Banish The Night Solar energy could help bring power to the powerless in Burma". Then I remembered another picture of the long neck tribe in a book named "Ebony-colored Virgin Mary", collections of poems by Kimiko Itami.

When I compared the two pictures, I thought those pictures are the same woman, one is when she was young, another one is when she got old. I was a little bit excited to find the coincidence. But now I am not sure of this, because the young woman's photo was taken in 1997, and Time's issue is 2014. Only 17 years between them. Though I still think the two women are very much alike.
long neck girl s.jpg
  Kimiko wrote in her poem "A woman Long Neck Tribe",
A Polish adventurer, Victor de Gorish Called the place "a country of giraffe women"
The spiral brass brace
Is first worn
When a girl becomes six years old
And a new ring is added on every three years
Until the girl reaches twenty-one year old
According to the Kayani Tribe legend,
A father used to be wind
And a mother a dragon,
The long neck-rings
Looked like a dragon somehow

(513) Rechargeable battery recycle box [調べる]

recycle box only.jpg

  I knew of this box from an information flyer of my community a few weeks ago. It is sometimes very hard to sort household garbage. I didn't know how to dispose of rechargeable batteries. I am a kind of man who keep social rules. So, I've kept two dead rechargeable batteries for a long time. One is PC's battery for two years, and the other is a battery of a cleaning robot, for more than three years. I was very glad to put them into the recycle box in the Habu branch of the Matsuyama City government.

  I found more detailed information at the site of BAJ (the Battery Association of Japan).

  Rechargeable batteries primarily use nickel (Ni) and cadmiun (Cd), cobalt (Co), lead (Pb) and other rare resources. Recycling is an effective means of reusing such rare resources without waste. Examples of this are the use of nickel and iron alloy in stainless steel, and the use of cadmium in making new Ni-Cd batteries. Please cooperate with recycling the used rechargeable batteries to make the most of rare resources.

  I am using an old MacBook, ten years old. My daughter gave it to me when she replaced it with a new PC. One day, I noticed its touch pad was rising and swelling day by day. Finally, I unscrewed the PC back cover and checked its inside. Its battery was swelled. A new battery was not available, so I gave up replacing it, and removed it from the PC. It was August in 2018. The battery continued to swell after removing from the PC.  I can read Li-ion recycle mark on it.

Lithium-ion battery

The lithium-ion battery is a secondary battery with a carbon negative electrode that can absorb and release lithium ions, and a lithium cobalt oxide positive electrode. When compared with Ni-Cd batteries and other similar batteries, lithium-ion batteries have superior features such as higher energy density and voltage.  Expensive and rare cobalt and other materials can be recovered from recycled lithium-ion batteries.



  The other is the battery of a cleaning robot, Roomba. Ni-MH is read on it.

roomba 2 s.jpg


Nickel-metal hydride (Ni-MH) battery

In place of the cadmium negative electrode of Ni-Cd battery, a hydrogen-absorbing alloy that absorbs and releases active materials such as hydrogen is used as the negative electrode. It is a sealed alkaline storage battery, and it has a higher energy density than an Ni-Cd battery. As with Ni-Cd batteries, rare natural resources such as nickel can be recovered from recycled Ni-MH batteries.

(512) I am not a trisector. [調べる]

  Underwood Dudley in Department of Mathematics Depauw University, explained about trisector in his writing, 'What To Do When the Trisector Comes'.

  A trisector is a person who has, he thinks, succeeded in dividing any angle into three equal parts using straightedge and compass alone. He comes when he sends you his trisection in the mail and asks your opinion, or (worth) calls you to discuss his work, or (worse still) shows up in person.

  One obvious characteristic of trisectors is that they are old. The typical trisector heard of the trisection in his geometry class, but did not succeed with his construction until many years later, usually after retirement. "His" in the last sentence is not sexist because almost all trisectors are male. From the two female calculation that we can be 95% sure that proportion of female trisectors is less than .04. Women have too much sense to waste time on such things. Trisectors are old men. An Illinoi lawyer wrote in 1953.

  Underwood said those trisectors are mathematical cranks (persons with a strange idea, because trisection with compass and straightedge is mathematically proved impossible.

  I came across this article while I'm searching for the ways of how to divide some angles into three equal parts. I am old and retired man but the big difference is that I don't mind what kinds of tools are used to trisect the angles. So, I am not the trisector at all. I just want to make a handmade protractor. My goal is to get an angle of one degree. I just wondered how each angle line is drawn on a protractor when I was a child. I had many questions around me when I was small but forgot most of them. But now I'm old and have much time to remember and think of some of them. So, I decided to try challenging those questions. And handmade protractor is one of them.

Here is a plastic protractor and my hand made one is next.

My plan was as follows,

(1) Draw an angle of 72 degrees.

     I should learn how to draw a regular pentagon.

(2) Get a 24-degree angle by dividing 72 into three equal parts.

     72÷3=24

(3) Get an 8-degree angle by dividing 24 by three.

     24÷3=8

(4) Get a 4-degree angle by dividing 8 by 2.

     8÷2=4

(5) Get a 2-degree angle by dividing 4 by 2.

     4÷2=2

(6) Finally get a one-degree angle by dividing 2 by 2

     2÷2=1


  First, I must learn how to draw a regular pentagon.

I can draw a right pentagon by knowing the ratio of red segment and blue one is (√5+1) : 2.

Next, I picked up one tool to get a trisection. It is a L-shaped ruler. Following drawings show how to divide an angle into three equal parts.

L定規4.jpg

I used this triangle instead of the L-shaped ruler. I use two line and two dots in red on the ruler.

This is how a 72-degree angle is divided into three equal parts.

72°÷3=24°

72÷3=24 s.jpg


I am dividing a 24-degree angle into three equal parts of 8 degree angle.

24÷3=8 s.jpg


I know how to divide any angle into two equal parts.

one degree angle s.jpg

Finally, I got a one-degree angle.

Now I'm satisfied to finish my challenge that I thought of but gave up in my school days.

Thank you for reading.
