Degree To Radian (or reverse)

How to convert from degree to radian or radian to degree?   

Using calculator:

→ What is 225 degree in radian?

We know that π = 180 degree so what we could do is using cross multiply:


How to convert from degree to radian or radian to degree?   

Without using a calculator:

30 degree = π/6 radian

Proof: π = 180 degree

180/6 = 30

60 degree = π/3 radian

Proof: π = 180 degree

180/3 = 60

90 degree = π/2 radian

Proof: π = 180 degree

180/2 = 90

45 degree = π/4 radian

Proof: π = 180 degree

180/4 = 45

These are the different degrees of special right triangle and we can use them to determine the measure of triangles, in radian, without the use of calculator.  

30-60-90 triangle

45-45-90 triangle


Seen But Can’t Reply

Perspective: The poem got inspired by a novel called The Rent Collector and was talking a character, Nisay (a child), who was watching his parents everyday and how he was expressing his feelings about them as well as what had happened to his family.

Every single day, all I see was tears swirling around a woman’s eyes.

I felt stupid everytime she talked to me, so I cry.

We lived on the same ground, we were born to be the same citizens, why can’t I understand what she said?

Wait, was that because I was only one year old and was always be in my bed?

I couldn’t express how useless I was at that age and I wished to grow faster

Not in a purpose to make friends but to help my dad and my mother.

I believed nobody could imagine what a day would look like for us

It was exhausting and frustrating, until some days my father created a fuss.

I didn’t mean to get sick and make my parents felt hopeless, but if I were to be healthy, you’ll see me jump.

But overall, the one reason behind everything was because our home was at the garbage dump.

Staying inside my mother’s embrace for almost 24 hours was always my only happiness.

But I did feel guilty when all she did was clean up my mess.

I tried not to cry most of the time because I knew it will provide more pressure to my parents

But what could I do if my feelings were constantly changing like the wave’s current.

I was a child who depended on remedy for all my life.

Sometimes just to receive money to look after me, my dad risked his life with gangster’s knife.

But finally, after a beautiful storm, there’s come a delightful rainbow.

Our family looked happier even if we did not show.

And that was when I got better

My sickness vanished; Thanks to my traditional doctor.






Poem – Trash VS Literature

The poem is written from a perspective of a woman who lives at the trash dump and is whose life is full of struggles, but then literature changes her life through storybooks. Also, this poem gets inspired from a novel titled The Rent Collector.

I spend many years of my life living at the trash dump, but it is more than just a normal lifestyle. Here are my stories:

Trash is my blood.

My whole life depends on garbage, even the stuff I found in the mud.

Trash is my food,

Which sometimes is the only things that can change my mood.

Trash is my medicine.

It can make my child’s sickness vanish so that he can grins.

Trash is my hope,

Which is the only thing that I could look closer to my future just like using a microscope.

Trash is my knowledge.

Since it is what I always depend on, I hope it could get me into college.

 But after all, I feel the world is very small, and that is when I meet an admirable woman, who teaches me literature. Since then…

Literature is my blood.

Every single day, it is flowing in my brain like a flood.

Literature is my food.

I can eat it all day without reaching my highest altitude.

Literature is my medicine.

It could help to heal all my life’s struggles and also give me lessons.

Literature is my hope,

A really powerful aspect of life that is very sustainable just like a rope.

Literature is my knowledge,

Since it is a part of education, it is a right, not a privilege.


Poem – Your Waste My Money

→ This poem is written from a perspective of a girl who lives at the trash dump and is depicting her future based on her environment.

How do you define your own happiness? Personally, rummaging around in trash is my happiness – every then and now.

If you were me, a piece of metal will make you say wow.

Getting cuts, Feeling sore, being robbed? I am used to it

But I alert myself, again and again, that I can’t quit.

Trash is my life, trash is my only hope – if you do not know

Now, you’re thinking of developing your country, but then where else could I go?

Waking up every morning, without the smell of a delicious breakfast is a part of my routine

Instead, all I smell is trash, which makes me never want to become clean.

Staying home will never be one of my options

Why? I’m very busy each day picking up trash; they are waiting for me to pick them up with impatient.

Up until these days, all I am obsessed with is trash

Even if it means sweating all day just to receive a little amount of cash.

Letting my family starve is my biggest fear

But what else can I do if messing around with waste is my career

I won’t be surprised if I get rejected for other jobs because of my background

But what else do you expect from a person whose parents were never found.

So please, if you don’t mind, give me a chance

I just need money, I’m not asking for an advance.

Otherwise, my child won’t be able to study

Because all I know right now is your waste is my money.


The Network | Performing

This term I am in an exploration called Performing. So basically, based on the name, there is a play called The Network that will be performed by our team. The Network is a play about how people are interacting inside the network and how it could give negative effects to them. Most of the members in our class was assigned to a character in a play that they will present, however, there are also non-acting role to work on: marketing team, fiance team, sound team, snack bar team, and sponsorship team.

I was in the marketing team; my job is to create a Facebook page about the The Network and design a posters for the play. Personally, I do faced many challenges: fixing the poster’s design multiple times, communicating with the sponsor team in order implement the sponsor logos on the poster, and updating the Facebooks’ posts for everytime there is something happening in class. However, at the end I did overcome these obligations.

On the other hand, beside acting and working on non-acting roles, we are also playing some games that could help to improve our acting skill. We enjoyed and learned a lot from those games.

Here are the pictures of what we did during class time.


Interior Design | Independent Discovery

Engineering is very a broad subject to me, but when it comes to designing (not building) a place, whether it is external or internal, it does get my attention. So, for my personal learning or an independent Discovery, I chose to explore about interior Design. For the first week, I did not get straight into all the details or start design stuff right away, but I did checked out some of my friends projects that they did before that were resembled to what I am doing. Both of them were using some software in order to decorate rooms and houses they liked. Afterwards, I got inspired by them, so I went on and download a different software with a feeling that I do want to design my own house. Before I get started in the program, I also watched some videos about it to get some foundation. Finally, after two hours of my interior design classes, I had came up with two rooms such as a bathroom and a bedroom.

Science behind Hulks’ superpowers

Physic behind superheros’ superpowers was one of the projects in physic class. So basically, everyone needed to choose one of their favorite heroes and then researched the physic behind their hero’s superpower. My hero was The Incredible Hulk, and here are the science that I found behind some of his superpowers. 

Hulk’s superpower

If you find yourself on a side of battle opposite the Hulk, you’re on the losing side.

The Incredible Hulk is a fictional superhero appeared in American comic books. Hulk had two appearances and they were based on his mood. He was green when he was mad and was back to a normal person when he calmed down. The madder he got the stronger he was. Hulk was called “The Incredible” because of his superpowers: leaping and jumping abilities, high resistance and durability, thunder claps (slamming hand to create large force), healing ability, survival in space, superhuman speed, and more.

On the other hand, most Hulks’ superpowers were related to physic and some biology. For instance, his thunderclaps, was very loud as a sonic boom explodes or a hurricane. As a humans being, at around 150 decibels (the unit measurement of the loudness), our eardrums will be destroyed. However, Hulks’ thunderclaps were about 300 decibels, which could melt and devastate stuff. But how could this be possible? Hulks’ thunderclaps was extremely powerful because when his two hands came together so fast, it created heat and had formed large force that then went toward the direction that his hand was pointing until it hit with object(s).

In The Incredible Hulk movie, the Hulk was originally a scientist named Bruce Banner who is a geneticist who worked on cell regeneration. However, one day the machine that was working with was fail so Bruce got hit by gamma radiation accidentally. Gamma radiation is the most powerful energy formed of light. Its wavelength is pretty small but carried a lot of energy. The idea of Bruce Banner became the Hulk is an example of epigenetic, the study of how environment affects gene. Bruce’s body turned to the Hulk whenever he got angry because chemical of the gamma ray reacted to his gene that would then created proteins and improved Bruce’s muscle size. Upon reading this was not the reason why the Hulk is green because gamma radiation was not green. It was because of the Hulk got a full body bruise when he absorbed the gamma radiation, and when that happened his blood cells that were under the skin will got damaged. So, when the cells got destroyed some sort of side effect happened, which showed as yellow, blue, and black, and one of them was green. Therefore, whenever Bruce Banner got mad the gamma radiation provided him with a massive body bruise that made him turned to an immense green beast.  

Although what had happened to Hulk might seemed realistic but some of his abilities were  actually not. If anyone were to get hit gamma radiation, he/she won’t gained any superpower; in fact, it will make the persons’ cells damaged and there will be a high chance that cancer will be occurred.

However, one of the Hulks’ superpowers could possibly exist in the real world, and that was leaping and jumping abilities. Both of these strength got three different stages: take off, flight, and landing. Anyone could become a better jumper or leaper, all they needed to do were, exercising their body, training hard, and putting enough time in order to get successful. Leaping and Jump had to do a lot in parkouring. David Belle, was known as the inventor of today’s parkour and he was a parkourist professional as well. David was literally could do almost the same things that the Hulk performed with his jumping and leaping abilities. The differences were their size and the distance of jumping/leaping. In The Incredible Hulk movie, there were so many things that were based on fact but movie itself didn’t showed. For instance, as mentioned earlier, the Hulk’s thunderclaps is about 300 decibel, which did not make any sense if any human could handle to the situation when the Hulk clapped his hands because human eardrum has already been devastated within 150 decibel.





Bambujaya grade 3

For the last round exploration I was in Bambujaya grade 2, but in this round I was in it again for grade 3 curriculum. As mentioned in the previous post, Bambujaya is a private school targeted Cambodian kids using Khmer curriculum. They hired some students at Liger to write add-ons for Khmer curriculum that will be used for the students. When I was in Bambujaya grade 2, I was written add-ons for social study and Khmer book. However, in Bambujaya grade 3, I am currently writing add-ons for math curriculum. From day to day based, it took me longer time in thinking of new activities as well ideas to write, since math is more complex and require a lot of thinking.

In term of writing those add-ons, on 9th of March, 2018, the Bambujaya people had invited all the students who had participated in Bambujaya exploration from all three grades to visit the school’s location. After I heard this news I was very exciting because instead of imagining the place of the students learning, right now we got the see it live. In addition, maybe it might be different from what we expected as well.

In fact, seeing the progress of the school made me felt ready to start primary school again because it looked very modern and most importantly was the curriculum with new with hands-on activities and more engaging for the students.


Khmer Sight Foundation at Metro hospital

On Feb 3rd, 2018, there are seven Liger’s students who volunteered to help Khmer Sight Foundation (KSF), a charity that conducts eyes screening, at Metro hospital located in Phnom Penh.

It was a very busy Saturday. There are a lot of people from the provinces came, and not every patient came with the same condition, some are their first time to check their eyes and some had already been doing the surgery the other day but needed to clean it out and take medicine from the doctors if necessary.

The seven of us got different tasks to do as well, three people were registering patients’ names, two were translating for patients, and the other two were bringing patients to the surgery and after they finished to get back home. The latter is my job and I can’t stress it enough for how I’m feeling blissful for those people. Not only having cataract surgery that changes their life but they are also building trust with the charity and as well as the Cambodians eye doctors.

Although it was a tough day for all of us I do enjoy helping my people. In addition, within the smile on their face after the surgery makes me feels that that day might be the best day of their life because they were able to get their sight once again.


Khmer Poem – School



 (បទ ពាក្យប្រាំពីរ)


កន្លែងនេាះច្រើនគ្រប់ទិសទី                          បុរសនារីគ្រប់អាត្មា

មនុស្សមួយចំនួននៅប្រាថ្នា                          ទីនេាះហៅថាសាលារៀន។


រាល់ព្រឹកព្រលឹមពេលសិក្សា                             ឮគ្រូអាចារ្យប្រដៅប្រៀន

ប្រឹងស្តាប់ប្រឹងយល់មិនដែលអៀន             កត់ពីក្តារខៀនហើយទន្ទេញ។


ពេលម៉ោងចេញលេងបានមកដល់            អស់ទុក្ខកង្វល់គ្មានទោម្នេញ

សិស្សានុសិស្សរត់លេងពេញ                            ខ្លះទៀតក៏ទិញនំចំណី។


ដល់ម៉ោងសម្រាកគ្រប់រូបកាយ                   សម្លេងក្អាកក្អាយលើវិថី

សម្រុកទៅផ្ទះគ្មានប្រណី                                 មិនដូចេ្នាះថ្វីច្បាស់ឈឺប្រាណ។


សូមកល្យាណមិត្តទាំងអស់គ្នា                        សំអាតទីធ្លាកំុបីខាន

ទោះវាមិនមែនការកំសាន្ត                             ប៉ុន្តែយើងបានសាលាស្អាត។


សួនច្បារខាងមុខដងទង់ជាតិ                    ដើមផ្កាឯទៀតមិនខ្វះខាត

ដើរកាត់ពេលណាចង់លួចឆ្លៀត                  បេះហើយយកសៀតទាំងញញឹ ម។


សាលាយើងអើយអ៊ូអរក្រៃ                              មិនថាយប់ថ្ងៃស្រស់ពព្រឹម

ពួកយើងប្រឹងរៀនទាំងសង្ឃឹម                     ស្អែកព្រឹកព្រលឹមវិសមកាល។


ៃសននឹកស្រណោះពេលកន្លង                    ពេលត្រូវដំបងធ្ងន់ឬស្រាល

ចងចាំមិនភ្លេចក្នុងខួរក្បាល                       ឈឺហើយរៀងចាលដឹងកំហុស។


This poem is talking about there is one place where so many people still can’t afford to go to; it is called school. Every morning teachers are teaching students with concentration and students are attempting to focus, listen and copy down the notes into their book. When break time comes students are very blissful, some are running around, playing different games, and some are buying snacks. Eventually, after a full morning or afternoon of studying, finally, it is time for students to go back home. The delighted voices on the road from those young bright minds are really showing how joyful they were after school. However, they also needed to be home on time, otherwise, their parents will be infuriated with them.

In fact, as students of any school, our role is to keep the school clean because it is just like a second house for every single person.  Even though it seems not the most satisfying thing to do but our school will look clean.

Over time, there will be a holiday. Students will be excited about their break but after a while, they will miss their school, expressly all of the old memories they have created with their friends and teachers.
