Title: Kite Runner

Author: Khaled Hosseini

Page: Whole book, re-reading it.


“For you, thousand times over.”

  • At the very beginning of the book, when Rahim Khan calls him from Pakistan, Amir recalls his memory of Hassan saying this quote. He also remembers what he had done to Hassan back then with the memory. Contrastingly, at the end of the book, Amir says the exact same thing to Sohrab. This implies Amir’s determination to pledge he would act to Sohrab as Hassan used to do to him.


  • Hassan and Amir used to play with slingshots. Back then, when Assef tried to harm Amir, Hassan protected him with his slingshot, threatening that he would shoot the shot in his left eye if he continued bullying Amir. At the climax of the story, when Amir was deadly punched by Assef, Sohrab hit the slingshot on Assef’s left eye, which was the part that Hassan would have aimed to.


  • Hassan congenitally has harelip from his birth. This was a characteristic that best represented Hassan at first glance. Baba called a doctor to heal the harelip, but it did not work. At the end of the book, when Assef beats up Amir mercilessly, Amir’s lip splits into two as if he has a harelip. The connotation in the harelip is sacrifice. Hassan sacrificed all his life for Amir, and even though Baba tried to change Hassan’s position, Hassan’s faith did not change. In addition, when Amir gets beaten by Assef while protecting Sohrab, his lips were split into two pieces. When he sacrificed for Sohrab, he eventually got the harelip.

The Kite Runner

From the beginning of the book to where I am now, what Amir had done to Hassan and how Amir and his father suffered the influence of the war were the main contents. Throughout the chapters, I found some points that might contain deepened thoughts.

  1. Blue kite

The most potent kite was the blue kite when the kite fight happened. When Amir cut the kite, Hassan ran to where the kite would drop and caught the kite. I felt the kite might represent a tear falling from an eye, and Hassan is the one who keeps that from falling down.

My final product

Why the product did not work?

Hypothesis #1 – Something was wrong with copper and aluminum strips

As I mentioned before, due to the absence of copper and zinc strips, I made the strips by taping copper tape and aluminum foil on a metal board. Since the strips were not made by accurate and professional machines or people, I could not determine whether the strips were suitable for this device. This is why I could not avoid the possibility of strips having a problem.


Hypothesis #2 – Voltage from the lemon battery was not enough to run a motor

This is the initial concern that I have considered from the beginning of the project. I was optimistic about this obstacle as I believed the motor would work, but the speed of the motor might be slow. Speed does not need to be fast in the carousel, so I ignored the problem.


To find out which one was the problem that disabled the product, I used a voltmeter to measure the voltage produced in the circuit. If the voltage is not observed, there is something wrong with the strips. If the voltage exists at a low rate, the lemon battery or the number of lemons is not enough to produce enough voltage to run a carousel. If the voltage is high, everything gets totally wrong, and there is a problem that I can even define.

Running the voltmeter told me that the problem was in the lemon battery not providing enough voltage to the carousel.


I used three lemons to actuate the carousel, but it still did not work.

Then, I came up with a question, “Will the product work if I put enough lemons in the circuit?”


Research about “Will the product work if I put enough lemons in the circuit?”

I found a post of a student that questions precisely what I asked. The student was doing a lemon battery experiment and tried to run a motor with the battery. She increased the voltage by 12.98V using a serial connection method, but the motor, which works with a single 1.5V battery, did not work.

Staff from the Korea Institue of Energy Research gave a reply to the question. What he said is:

A certain amount of voltage and electric current is required when running an electric device. In your case, it seems that the circuit’s voltage is high enough to actuate the motor as plenty of lemons are serial connected. Then, the problem would likely be in the intensity of the electric current, as it is expected to fall short to operate the motor.


My analysis

Rephrasing the word from the staff, even though the voltage was high enough, the intensity of the electric current might fall short due to the increased resistance. This is happened because of a special relationship between the intensity of electric current, voltage, and resistance.

Ohm’s law explains the relationship between the three components. Specifically, the first formula [V=IR] shows if the voltage is constant, the intensity of electric current decreases when resistance increases. Using the serial connection, the voltage was high enough in the lemon battery. However, resistance also increased hugely because it took too many wires to create a serial connection. Consequently, the intensity of the electric current cannot increase.

Therefore, to answer my research question, it turned out that increasing the number of lemons would not help running the motor as while voltage increases, resistance also gets more extensive and does not let the intensity of the electric current increase.


Reflection on my skills

I had a clear division of success and struggle throughout the project. The successful part is 3D modeling the pieces. Although the project requires precise and accurate measures and calculations, I modeled 5 works without a significant error. This allowed me to save time and use it in other sections. The field that I need improvement in is assembling the pieces. It was obviously the most challenging part. I took multiple classes to straightly align the shaft of the motor and pillar. It took 30min-1hour to stick horses on the bottom of the roof. Throughout the project, I acknowledged that my weakness was in manufacturing skills. I might spend less time planning for further projects while providing more building time to cover my manufacturing skills.

Title: the curious incident of the dog in the night-time

Author: Mark Haddon

Page: Finished

I finished the book with a help of an audiobook. I continuously listen to a soundtrack that reads the book, which helped me a lot in saving time. Since I had enough time, I actually read the book, though.

In my opinion, the moral of the story is “just do it rather than staying still.” In the story, the main character Christopher has autism which is a mental disorder that gives whirlwind changes to a patient’s thought mechanism. Even though he sometimes showed some frustrating behaviors caused by autism, he ultimately succeeded in his goal and got the things that he wanted to have. What he did was brave and courageous.

While I was reading, I could not fully understand why Christopher chose to live with Mother rather than Father. It is certainly frightening for Christopher to know Father’s action of killing Mrs. Shears’ dog because she gave more attention to Wellington than his family. It is reasonable that Father expects Mrs. Shears to help him instead of the divorced wife, but it is not her duty to care about him. The action that he showed was presumptuous and violent. However, except that, Father showed his dedication to Christopher and he did all he could for him. In comparison, Mother cheated on her neighbor, Mr. Shears, and ran away, leaving Christopher and Father. However, after leaving them, she wrote letters continuously to Christopher in order to lessen her guilty and justify what she did to Christopher and Father. Comparing two parents, Father was normally patient and thoughtful but he was too stressed at the time he killed Wellington whereas Mother was usually irresponsible and tries to justify her faults.

Title: the curious incident of the dog in the night-time

Author: Mark Haddon

Page: 48

I am still reading the very front part of the book. Though I haven’t read the part Christopher dealing with this incident, I was able to predict what is going to happen.

In the chapters I read, I could see some evidence that Christopher misses his mother a lot though he himself did not know that he does. For example, while he was talking about where his mother has gone, he mentioned that he sometimes looks up to the sky and thinks about his mother still exists as a small molecule and would come down as rain or snow. He unconsciously revealed his sincerity, wanting to believe that she exists somewhere. Furthermore, it was also shown up in chapter 73 that he remembers that his mother said, “You are going to drive me into an early grave.” He did not mention it clearly, but in his tone of speaking, I feel like he feels guilty for his mother’s early death and thinks it is partially his fault. Through the hidden evidence in the story, I was able to predict that during Christopher solving Wellington’s death, he might get his mother’s vacancy off his chest. Specifically, I strongly feel like the author will use rain/snow as an object that symbols Christopher letting his burden go since rain/snow stands for remaining Mother’s trace and it allows readers to feel the visual effect of letting something go.

My objective is to read about half of the book during the weekend. To figure out whether my interpretation is right or wrong, there is no way but to read more chapters.


+) Additional ideas

How is it possible that Christopher was blocked to resume detection by his father but solve the mystery?

He often shows inappropriate behaviors but I don’t see this as a severe stage of autism. If the author is not talking about people with autism still being the same person as others, what is the moral that the author trying to express through the character Christopher?

So far, since I started reading 10 minutes ago, I don’t even know what is going on. All that I can say is that the main character Christopher has autism and he is going to struggle being witnessed as the last person who contacted the dog. I wonder how the child with autism can get through this struggle.
