09.00 AM in class XI Natural Sciences
Lina had just collected her Olympic selection exam papers, as did a friend who was in the same major as her. "Hmmm, it's a relief, the written test has been passed. Just waiting for the interview exam tomorrow." so he said to himself. While picking up his favorite backpack, suddenly from outside the classroom a voice that is very familiar to his ears calls his name in an annoyed tone, "C-A-R-L-I-N-A".
"Lina, look at Fika, it looks like she's being punished for running away with her classmates." Obviously Anita.
"Eh, but he said your name Lin, is it possible that Zain likes you, so he asked your name to Fika." said Evan.
"But Fika told Zain in an annoyed tone to Van. Is it possible that Fika wouldn't be willing if Zain became Lina's friend and close to her?" said Anita.
"Could be Ta. What do you think Lin?" Ervan asked Lina.
"I don't know, it gives me a headache. I'd better go to the park, find a place to read a book."
Lina just left without caring about her friend's chatter. The school garden is Lina's goal during free time. It is very comfortable there, the wind blows gently, coupled with a beautiful decoration of a combination of rose and frangipani flowers. Lina took out a physics book in her bag. Her dream is to become a nuclear expert, but she also has to master physics in order to understand the beautiful universe.
"In a fly which is often regarded as repulsive, it is not sufficient to flap the wings up and down to maintain a smooth flight. The wings must change angles during each stroke to produce thrust and lift the body. The wings have a certain flexibility for turning depending on the type of insect. The muscles of flight mains, which also generate the power needed for flight, support this flexibility.For example, in order to fly higher, the muscles between the wing joints contract further to increase the angle of the wings.Observations made using high-speed film techniques revealed that the wings left oval trails when flying. In other words, flies not only move their wings up and down, but also move them in a circular motion like rowing a boat in water. This movement is made possible by the main muscles earlier."
"Dear God, thank you for opening my eyes and moving my heart to read this book. With the intricate movements of a fly that is more agile and sophisticated than any of the most magnificent aircraft in this world, You must be the Greatest "engineer" and "physicist". Due to the nature of nature which is basically predictable, humans can then imitate nature through physical laws, such as the laws of motion, the laws of kinematics, the laws of dynamics, etc. Basically these laws are a simple imitation of what God created in universe."
"Lin, what are you doing?" Asked Mr. Bakti, Lina's homeroom teacher, which interrupted his reverie.
"Read physics books, sir, the contents are really good. There are many writings that can open my way of thinking to continue to be grateful for God's blessings. I want to be an obedient servant, sir, who can be grateful for all of His creation."
"That's good Lin. So, in what way are you grateful. Just be an obedient servant Lin? Don't just be an obedient servant. In Islam, there are three keys to being a servant. Hablum Minallah (good relationship between creatures with Allah), Hablum Minannas (good relations between humans and other humans), and the third is Hablum Minal'alam (ie good relations with the surrounding nature). You are grateful, that includes Hablum Minallah Lin, but where are your Hablum Minannas and Hablum Minal'alam?"
"Gosh, sir, I forgot about those two things. How can I, sir, do all three at the same time?"
"That's easy Lin, you write articles on the internet, that includes Hablum Minannas. Why? Because with your writing everyone in the world can read it, and their knowledge increases even if it's a little. For this Hablum Minal'alam which is a little difficult Lin, you have to can provide benefits to nature from the knowledge you gain. How do you do it? At least you should be able to produce one product from your research for plants."
"Thank you for the advice sir, I will try from now on to write first."
"Yes Lin, good luck." Pak Bakti said when he was about to leave the park.
Lina also left the school garden, and got ready to go to class to attend Physics and Biology lessons.
