The Story of Sigma Men
9. Energizing
This morning in class.
“Who knows what energy is?” Miss Dewi Sartike threw a question to all of her students.
Uzzlah raised his hand.
“Yes please, Son! Keep mentioning the split too!”
Uzlah said, “Energi is the ability of an object to do business. Divided into three, namely kinetic energy, potential energy, and mechanical energy.”
“Good. Explain the meaning of kinetic energy and mention examples in everyday life!”
Uzlah answered again. “Kinetic energy is the energy possessed by an object that has mass due to its motion. Example, a kicked ball and a planet circulating around the sun.”
“Absolutely. Where is this other one?” asked Bu Dewi Sartika while scattering his gaze to the corner of the class.
Suddenly Zahid raised his hand, interrupted and said, “The second example is not right. It is better if for example the moon around the Earth, because the heliocentric theory is still debated.”
Miss Dewi was again made dizzy by the child. Because Zahid does not focus on learning through LKS and print books alias he learned from many sources both in other books and the internet, then Zahid often disagree with the teachers.
Then Miss Dewi diverted the issue. “Potential energy, explain the definition and please mention the example in everyday life!”
Again Uzlah replied, “Potential energy is the energy possessed by an object because of its height or position against the reference point. For example, a basketball that falls from a certain point.
“Continue Mechanical Energy!”
“Total of kinetic energy and potential energy in an object used to do work. For example hydroelectric power plant.”
Next he wrote about it on the board. Motorcycles weighing 110kg move at a speed of 5 m/s. Count how much energy?
Zahid stood up. “Bu, what the hell are we solving such a problem for? If you use a motorbike, it is important that the engine is good and the gasoline is enough. The important thing is that we know how fast it is. No need to find out the kinetic energy of everything.”
But Miss Dewi Sartika remained calm. Teachers should not be rash to judge the ugly of their students. It's still early school anyway. Stay slow.
“We need to learn something very basic before we know how a television can live and a motorcycle can run, Zahid.”
Uzlah wrote on the paper the answer to the problem on the blackboard. Afraid that Zahid would be judged ugly by the teacher, Uzlah gave the paper to Zahid, let Zahid answer the question.
“For there!” whiskey Uzlah.
Zahid took the paper and went forward.
EK \= ½ m.v^2
EK \= ½ (110kg).(5m/s)^2
EK \= ½ (110kg).(25m^2/s^2)
EK \= ½ (2750kg. m^2/s^2)
EK \= 1375 kg.m^2/s^2
EK \= 1375 J
The Goddess maam was stunned while smiling bitterly. He thought, this strange child, was protesting but now he can answer. Next he gave another question about the value of potential energy and mechanical energy.
Uzlah wrote all the answers and Zahid came forward.
Unknowable
Height of object \= 5 m
Object mass \= 0.1 kg
g \= 10 m/s^2
then,
EP \= m.g.h
EP \= 0.1 kg x 10 m/s^2 x 5m
EP \= 5 J
Unknowable
EK \= 5 J
EP \= 5 J
Then,
EM \= EK + EP
EM \= 5 J + 5 J

This morning in class, biology class.
Bu Sri wants to be different at the beginning of this school. He turned on his laptop and displayed a clearly visualized slide near the blackboard.
“Today we are not open. Please look ahead!”
On the screen clearly displayed a large and foreign sea animal. Perhaps most of them have never seen it on books, television or the internet.
“Who knows about this fish? Explain!”
The class was silent for ten seconds. The teacher watched his students in front and back, left and right. Everything is silent.
Zahid nudged Uzlah. “That's right.”
Uzlah whispered. “Books bought by dad the other day. At that time we read together at your house, Zahid.”
Zahid then raised his hand. He stood up and replied, “Pope Humpback. Or the humpback whale. Its Latin name is Megapetra Novaengliae. Its length can reach sixteen meters and its weight can be up to forty tons.”
Then Bu Sri appreciated the courage of the one teenager. But suddenly and suddenly.
“Bu,” says Zahid fast. “Who named the fish Humpback Whale? And who gave his Latin name?”
“All the explanations are in the science books, son. We just learn it.”
“Not so Ma'am. Why do we always learn something that Westerners find. No one in Indonesia is smart, what?!”
“We're smart, Zahid. It's just that researchers from outside first do research and find a discovery.”
“Do we never do research?”
“Our people all the time do research. Teachers, lecturers, and students do research.”
“Well why there's no name there? It's always the name of a Westerner. Is this all conspiracy or conspiracy?”
“No conspiracy Zahid. In fact, we must thank scientists who have struggled to do research, exploration at sea, write journals, and expose it so that we very easily know a science.”
Do not want there to be a discussion that is too long with Zahid, he finally shifted the next slide. “Well if this is a fish? Please explain!”
Then Uzlah raised his hand. “Dugong or sea cow or often called Duyung. Many are also found in Indonesia. It can weigh up to four hundred kilograms. The name of the book is Dugong Dugon. Phylum Chordata. Mammalia Class. Sirenia Order. Dugongidae. Genus Dugong.”
“OK. Up next. Try something else!”
Twenty seconds later, no one answered.
“Zahid or Uzlah, answer!”
They both even fuck each other. Not because of forgetting, but fear of being counted smart. They are both amused to know the early material of this school apparently they have studied. It could be the same source. Yes it could be.
By reason of win win solutions, finally Uzlah who answered. “Fish Barracuda. Its scientific name is Sphyraena. Has very sharp teeth that are effective for paralyzing the animals that will be eaten. Can be found in tropical and subtropical waters.”
“Now the last.”
After seeing the familiar animal, all the disciples simultaneously shouted, “CUMI-CUMI....SQUID!!!”
The teacher nodded. “Precisely less. Can anyone explain?”
Zahid took a breath. Wink of left eye Uzlah as sign “Jawablah!”
“Well that's a Giant Squid. Latin name Architheuthis. He's an inverterbrata, aka no spine. He lives in the sea with a depth of between two hundred to a thousand meters, Bu.”
Then all the students of one class and the teacher carefully listened to the lecture from Zahid the boy who had just entered puberty. Uzlah smiled amusedly watching Zahid and was also surprised that he had a pretty good memory.
“Friends,” Zahid rolled his gaze. “Be careful with those tentacles. Can nyedot. Maybe our brains will get sucked. I will not be able to think about our dong anymore. He he's. The tentacles there are spots, so it looks more like a saw, well that's the point to prey on his game animals, Friends.”
A class of mangosteen understands. But not as imagined. Again Zahid did something. This time it is not anti-thesis and not a kind of paradox, but just an overflow of his feelings towards biology lessons, a kind of autocriticism could be.
“Bu, but I don't like biology lessons!”
Uzlah who is right next to him is bowed. Then he scratched his head. Start again, he thought.
“Bu, this biology lesson is different from science in general, such as chemistry and physics. Wh why? Because in this lesson I didn't find a mathematical formula. All definitions, classifications, divisions, and explanations. Just theories. There are no numbers. Don't don't let this biology not be part of IPA.”
Madam Sri lowered her glasses. “This biology is part of IPA, part of natural science. Because what we are learning today is based on scientific studies that are objectively proven and acceptable to many people, especially academics, like us-we are.”
“But Mom, our job is just to understand and memorize. We are not required to make some sort of analysis and calculation. For me this is not so challenging. So biology is the easiest science to do Bu.”
Thus Zahid, he often deflects logic, distorts facts, breaks assumptions, and later, he will rectify a law, which has been recognized for centuries. See later.
