The Mirror and the Molecule


My mother asked me to make tea when the cook was in the kitchen. I asked her to wait until she was done. Later, I found that she had made it herself. She offered me some. I had it when the class was over. The software version of this phone updated itself.
Students left after noting down Addition and Subtraction problems. It was the second batch. The elder solved the first batch. The younger hardly attempted them. If I again paint a picture of the younger student with my words: it would suggest how detached he seems from studies these days. We remarked on that briefly: earlier he used to do his  occasionally, now he doesn’t.


Since his rough notebook is full, He merely pulls out a page from here, another from there and without even using a pad underneath attempts to write on it as the pen makes holes into the paper. Later, he takes this paper in his hand and pokes it further with his pen. I ask him to not do that. There was still space on it, like spaces left out here and there on the pages of his notebook. He crumbled the torn page and keeps it in his bag. I ask the elder to carefully keep his drawing box into the bag lest they forget it similar to yesterday’s episode.
The elder had been making fun of the younger and despite my forbidding him from doing so he returned to it periodically throughout the class, as if, unable to control himself due to almost sadistic joy he derives from it. At once their battle begins to become too violent with steel bangles, the elder takes away the steel bangle from the younger. I ask them to be careful with that. The younger gives him three- four retaliatory blows.
Meanwhile there’s a bet about who can do 5000000-2344678 faster. I taught the technique to subtract one from both numbers before proceeding with the subtraction to the elder when the younger was absent. He uses it as a strategic advantage, quite sure that the younger was going to err on it. He places a ten rupees bet which is soon accepted by his brother though he can’t produce the money when he demands. Though I don’t promote betting I know this isn’t going anywhere. Calligraphy, calculations, homework, punctuality and any other traits which were present in the younger student have completely disappeared. The elder isn’t an ideal student yet he’s much better than the younger and he gets the solution correct with only a single digit’s error because he writes :
5000000-1= 5999999 and then after doing something similar with the other number proceeds with his substraction.
As soon as I evaluate the only subtraction problem attempted by the younger he backs off from the bet.
The elder threatens him.
“Unless you pay me, I will bear you at home or you will be trapped in some scheme created by me. I will tell others to withdraw money from you where I am supposed to pay.”
That’s just a ten rupees affair. But that’s a big deal. The morale of the younger student is already down. Yesterday, he had to make another trip to collect his bag.
This doesn’t prevent him from grooming himself. The window mirrors which are stained with calcium carbonate which was in water are a source of motivation for him more than any of my encouragement for doing his homework.
Adolescence.
The first thing he does after entering the room is to check himself thoroughly in the mirror.
Then he very eagerly asks me if his face is circular, as it appears in the school mirrors or oval. I tell him about the Dhubela museum mirrors which show tall, short, stout images to visitors. I tell him that his face is not circular in shape. At this point the elder also grooms his hair. Even his face isn’t circular.
I had to request the younger one to not touch his hair anymore. The elder is almost sleepy as I read Laws of Motion. The chapter is about motion. There’s an introduction about Galileo. It’s detailed. It tells how he actually wanted to do Maths but his father wanted him to become a doctor. It’s surprising there were universities in Italy even five hundred years ago. He published a book on work based on Archimedes at first. His heart wasn’t in the study of Medicine.
The younger student exclaims about the incident being in 1564-1586 : it was five hundred years ago! He’s almost right. I consider it a positive sign. At least he’s taking some interest. It’s not.
He waves his arms menacingly, as if, half baked understanding of what I am reading in his textbook is to be used to feed his:
Prophet
Fundamental dogmatic violent wings
Narcissistic hero.
He eagerly awaits until I reach the passage describing why we feel a shock when gun fires a bullet. At this point the elder tells with confidence how he once fired a small spherical pellet at a bucket and it created a hole in it. I am teaching them the third law of motion:
“Every action has an equal and opposite reaction.”
It’s by Sir Issac Newton.
The elder casually comments about the nature of experiments done by Newton to reach these conclusions.
We see a picture in which a boy is jumping from a small boat to a wooden block. The picture is casually made. It’s not an illustration. It was supposed to give a hint. It wasn’t a drawing competition. I wanted the younger one to draw pictures like he used to do before. In previous classes. He’s more concerned with his hairstyle.
He interjects about friction when it’s mentioned in the textbook. I describe it to him. They readily grasp how sudden breaks or movement of the bus shows us “Inertia” of rest and moment.
Reading Hindi text feels slightly different. There are numerical problems based on the Newton’s laws of motion.
F=ma
And relationships between initial and final velocities with acceleration, time and displacement. We skip these because they’re not oriented to attempt them.
The chapter is covered faster than they expected. We continue with the practice of Algebra. Before moving out they check Instagram feed. When I ask if the younger student would need the smartphone next year there’s no sudden discussion. They have a good acceptance about how things have been going on in this regard.

Horses can smell human fear

And it makes them even more frightened.

How’s it a  useful form of information ?

It’s certainly going to increase the fear threefold when you know you have nothing to curb that smell or

There will be a new product to buy.

Resonance

Read the note I had scribbled before the class. Edited it a bit. Students arrived slightly later than usual, one after another. The elder arrived first. He wasn’t sure if the younger was coming behind him. I asked him if he went to school, to which he gave an affirmative reply. There were no studies during the day. Nothing was taught. They sat whole day. All of the students from all of the sections in a single classroom. Not more than fifty to sixty students. It wasn’t the full strength. I think it might be about ten percent of attendance in most of the sections due to extremely cold weather for the region (10-12 degree centigrades).
He showed me a leaflet as I was reading a chapter from their Science textbook  to them. It was a colorful print out of the time table for their yearly examination. It contained a schedule for the ninth class examination on one side and eleventh class examination on the other.
After I described them the schedule for their final examinations: he wanted me to read the back side schedule as well. Though I told him that it didn’t concern them as it was for higher classes, he insisted that I read that out to him. He was curious. I told him that their exams were going to begin on fifth of March whereas the exams for standard eleventh were going to start from twenty fifth of February. As he requested I even read out the note in the fine print at the bottom of the leaflet which said: “Verify the schedule with the notice board in your school.” I explained them what it meant.
When I told him that there wasn’t much time after this month as February is a shorter month he was surprised. I told him that it was his second attempt. He told me that his classmates are sure that he would pass. They even said that he did not need to study. I advised him to continue to study as much as possible. I think they would attend only a few classes now. Not more than thirty I guess.
When I compare the printed time table with that of our times: I have slight trouble recalling if there used to be a printed time table at all. And if there was, it was not this fine.
I asked them what they wanted to study. The elder brother hadn’t brought the maths textbook saying that it is in younger’s bag. Younger didn’t bring his bag or homework and showed insouciance when I asked about it. I wonder if nonchalance would have been a better word in the last sentence.
They take some time to decide which chapter to study from their Science textbook. I started reading from the eleventh chapter which is on sound waves.
I read it and take certain pauses to describe it to them. Tuning fork is used to study resonance. I doubt they have seen it in a lab. I hadn’t seen it either. There’s a brief introduction of Rudolf Hertz whose contribution to study of frequency was honoured by naming the unit for frequency with his surname. It’s represented with Hz. Frequency, Wavelength and Amplitude are defined with wave diagrams. Regions with higher  and lower pressure waves in the sound transmission. Noise and music are considered as waveforms. Music is generally low amplitude waves. Noise is high amplitude waves. Most of the cultural festivals and processions convert music into noise with an aim to send their message to as many as possible. Then there are follow up questions on these. Can there be noise disguised as music? Yes. It might have been a mystery a few centuries ago. In the digital age almost everyone is familiar with it.
Mother brought a cup of tea after class as I was relaxing after having put the chair back to its designated spot. She had forgotten tray. I told her it was alright. I asked her to tell me when the gas cylinder needed to be changed. After a while grandmother called me out and I changed the cylinder by removing regulator from the old one and placing it into the new one. Another task completed. The symbol for the Resonance chosen by the institute where I was preparing for the competitive exams after school was similar to the Mandarin character for person. It’s eight. Or is it person?
Why do they look so similar? I looked up online:

Minimalism: These are some of the oldest characters in the Chinese language. Because they represent very fundamental concepts, they were designed with the fewest strokes possible (2 strokes).
Evolution: * Person (人): Originally a profile view of a person bowing or walking.
Eight (八): Originally meant “to separate” or “divide.” Since eight is a number that can be divided perfectly multiple times (8 \rightarrow 4 \rightarrow 2), this symbol was borrowed to represent the number.
Helpful Tip for Writing
If you are using a brush or a pen, the Person (人) character always starts with the left stroke, and the right stroke “leans” on it. For Eight (八), you intentionally leave a gap at the roof to show that the two sides are “divided.”
In the context of the Mandarin characters we just discussed, the character that most poetically represents the concept of Resonance is Eight (八).
While neither character literally means resonance, Eight (八) is the best fit for two scientific and symbolic reasons:
1. The Concept of “Dividing” and Sound Waves
The original meaning of 八 (bā) is “to divide” or “to separate.” In physics, resonance occurs when a vibration is transferred from one object to another through a medium.
Think of a tuning fork: its two prongs (the two strokes of 八) must be separated and symmetrical to vibrate at a specific frequency.
If the prongs were touching (like in the character 人), the friction would dampen the vibration immediately, and you would get no resonance at all.
2. The Visual Symmetry
Resonance is a phenomenon of harmony and symmetry. The character 八 is perfectly balanced and open.
In a Resonance Tube experiment (like the one we discussed using a swaritra), the sound waves reflect back and forth.
If you look at the shape of a standing wave (the pattern created during resonance), it often looks like a series of loops that mirror the open, flared shape of the character 八.
If we look at the actual Chinese word for Resonance:
The Chinese word for resonance is 共鳴 (gòngmíng).
共 (gòng): Means “together” or “common.”
鳴 (míng): Means “the cry of a bird” or “to make a sound.”
So, resonance literally translates to “sounding together.” If you had to pick between the two simple characters, 人 (Person) represents the source (the observer or the striker), but 八 (Eight) represents the physics of the instrument (the open prongs of the tuning fork).

United Nations World Food Program: Free Rice !

1. I had a good night’s sleep.

2. In the cricket academy: the coach asked my whereabouts. I told him the bare facts. What would have been the use of telling him about the journey. I asked him if it was a trouble to be around. He said that it was quite the contrary. That he liked my presence.

3. The Twilight was one of the most beautiful songs and paintings wrapped in mysterious songs of birds returning to their nests. I saw bats dancing. Perhaps it was closest to what I might have called home. Comfortable playing ground. Playing the ball. Eons and eons. Homage to vallalar and the ethereal shrine in Thillai.

4. I have been training for more work than I had done before. My forte turns out to be vocabulary and it’s wise to coach students only for basic grammar and vocabulary instead of teaching them all the subjects. This is the conclusion I have reached after many months of experience.

5. Walking. Counting. Vocabulary. Advertisements. Interrelationships. These are the most highlighted domains I have been working on. Though the scientific method is there it mostly eludes.

6. The game with the balls. Dancing light of Grace. Rests in peace.

7. Parish Church. Pariah puranam. Pariah means outcastes. Civan welcomed all into his team irrespective of class, caste or creed. Ramananda, Kabir, Raidas and Valmiki are shining examples of middle age saints who gained fruition after living like outcastes. They opened their doors for all and helped them gain eternal life like Christ

Achievement!

“Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement. ”

I heard that with awe and wonder. It was beautiful wisdom on her exquisite lips which tasted like nectar of immortality. She was my destiny. The fountain of youth. The source of beauty. Her forgetfulness was peculiar. On one hand she was unable to tell the name of the first US president even after repeated discussions, on the other: she said she was well versed in Greek mythology.

“So what is the name of the first US President?”

I asked again!

Longing for an accurate answer. Ah! She meant a wonderful world to me. She was my delight.

Abraham Lincoln!

Both eyes closed
Dropping to the ground.

As she snapped out of her reverie, she frowned in concentration. I was amused. I hope to hear from you soon kroon afternoon monsoon. A day might come when you would utter George Washington in response to the question and continue to do so. It will be the event I have been waiting for since an eternity. I looked at her blonde hair. This is the most important day of my life, I thought.

It’s rather complex, but the development of the human psyche is a truly awe-inspiring thing.

Wisdom is the oneness of mind that guides and permeates all things.
