How to Create a Good First Impression Through Email Writing

In the professional field, whether it is school or work, it is important to be able to write a concise and purposeful formal email. In this world of networking, the ability to communicate well through writing can be really helpful in creating a good first impression with someone — a potential mentor, business partner or employer — since a well-written email may indicate professionalism and dedication.

The second round of literacy was all about effective communication, and email etiquette was part of the course. An important takeaway for me about writing an email was to keep the email concise and professional. We should consider that the recipient is probably really busy and we are asking them to spend time on us, and by keeping the email to the point, we’re doing us and them a great favor.

There are many components to constructing a well-written formal, including the subject line, salutations, introductions, purpose, and conclusion. To put what we learned about email etiquette to action, we were required to write a formal email to a made-up fashion company to request for an internship. So below is the written email, broken down into different components

Subject: Request Information About Internship


Dear Mrs. Ellie Holte,


I hope this email finds you well. My name is Thathiny Tep, from the Liger Leadership Academy in Phnom Penh. I am writing this email regarding the internship opportunity offered by your fashion design company, Blossom. I heard briefly about this opportunity from my learning facilitator here at Liger.

[Content and purpose]

I am interested in the position assistant market researcher and believe that position is suitable for me. I know that Blossom is known as one of the most successful business in Cambodia and it would be a great pleasure if I get to experience working there. However, I’m still unclear about the requirements for the applicants since you haven’t had much information about this opportunity on your website, so I’m writing to request for further information and how to apply.


I am looking forward to your response regarding my inquiries and applying for the position.

[Final salutation]

Best regards,


Analyzing the Graph of a Polynomial

In pre-calculus, we investigate many topics in the subject, one of which is graphing polynomials.

Above is the graph of the equation (x-2)/(x2-2x-8). Using the graph, we can analyze many characteristics of the polynomial. First, we can identify the y and the x-intercepts, when x and y equal zero, respectively.

We can also recognize the vertical asymptotes, which is the value of x that the graph never touches. In this case, the vertical asymptotes are when x equals to -2 and 4. We can also describe the behavior of the graph as x approaches the vertical asymptote from different directions. For instance, as x approaches -2 from the negative side (left), y approaches negative infinity (-∞), and as x approaches -2 from the positive side (right), y approaches positive infinity (+∞).  The same behavior applies to when x approaches 4 from both directions.

The horizontal asymptote can also be found using this graph. As seen above, the graph never touches the point y equals 0. The behavior of the graph can be observed as y approaches zero from the negative (below) and positive (above) side. In this case, as y approaches zero from below, x approaches -∞ and as y approaches zero from above, x approaches +∞.

Why FDR’s First Inaugural Address Still Remains Powerful Today

In literacy essential, we examined the topic of American history as our first unit. Using the platform CommonLit and other resources, we dissected the speech “Give Me Liberty, Give Me Death,” understood the causes of American Civil War, analyzed the Great Depression and etc, while also expanded our vocabulary usage and studied grammatical concepts. At the end of the term, we were able to choose our final assessment project. I chose to write a rhetorical analysis essay on President Franklin Delano Roosevelt first inaugural address “Only Thing We Have to Fear Is Fear Itself.” Below is the essay I’ve written about how and why FDR used the rhetorical appeals in his speech.  

Rhetorical Analysis on FDR’s First Inaugural Address

“Only Thing We Have to Fear Is Fear Itself”

Starting in 1929, one of the most tragic economic crisis, the Great Depression, occurred. This catastrophe caused many citizens to be unemployed and bank loans were halted. However, when President Franklin Delano Roosevelt (FDR) was elected in 1932, he promised to bring America out of the depression by providing jobs to citizens and strengthening America’s policy. In his inaugural address — delivered on March 4th, 1933 — President FDR explained the economic issues that America was facing and presented his solutions to the audience. Throughout his rousing speech, FDR offered logical solutions about the problems arisen in the United States from 1929 to 1939. He projected his speech in a unifying language that built his credibility to “fix” America and reassure Americans to believe through government involvement and collaboration, America could recover.

Throughout his speech, President FDR used the logos appeal to describe the problem America faced and the reason behind his proposed solutions to reform the US Constitution. FDR explained the dire condition of the economy concerning America to reinforce the importance of his speech. He elaborated on the problem by stating, “values have shrunken to fantastic levels; taxes have risen; our ability to pay has fallen; government of all kinds is faced by serious curtailment of income…” He also proved his solutions would work by asserting, “we are stricken by no plague of locusts,” and “our Constitution is so simple and practical that it is possible always to meet extraordinary needs by changes in emphasis and arrangement without loss of essential form.” These logical reasons persuaded the audience that his resolutions were necessary and had the ability to pull America out of the Great Depression.  

In addition to the appeal to logic, President Roosevelt used ethos by communicating in phrases that built his reliability with his audience and guaranteed he had the ability to heal his country. He assured the audience that he will solve the economic issue of his country by claiming, “I shall spare no effort to restore world trade by international economic readjustment, but the emergency at home cannot wait on that accomplishment.” Later in his speech, he went on to say, “for the trust reposed in me, I will return the courage and the devotion that benefit the time. I can do no less,” which further ensure his audience. With these promises, President Franklin Roosevelt had made his citizens believed that he would support them.

Similarly, FDR established a relationship with his citizens by using pronouns such as “we” and “our,” and called his citizens to collaborate with the government in order to build up the trust for him. He emotionally conveyed, “we face the arduous days that lie before us in the warm courage of the national unity.” With this he called the citizens to action by pleading, “if I read the temper of our people correctly, we now realize as we have never realized before our interdependence on each other; that we can not merely take but we must give as well.” By entreating this, he emphasized the importance of collaboration to both the citizens and the government, therefore, convinced Americans to rely on him while also cooperate.

On the whole, President Franklin Delano Roosevelt effectively delivered his first inaugural speech with rhetorical appeals such as logos, ethos, and pathos. His influential speech is still engraved in American citizens today. Besides, he did not just present his solutions in his speech but also execute them to action. Many of the policies that were established during his time in office still serve Americans today, and this is part of the reason why he remains one of the most respected American presidents.


Why does Flame Change its Color When Contacting With Different Chemical?

When an element has contact with flame, heat excites the electrons in the atom. This allows the electron to go from their ground states to a higher energy level.  In this state, the electrons are unstable, so they needed to emit energy to return to their ground state. In this case, we could see a color that corresponds to the wavelength of light emitted by the energy in the form of electromagnetic radiation. 

Above is an explanation of why we see different colors when elements or chemical compounds are put with flame. To see this concept with our bare eyes, we did the flame test lab as part of our chemistry class. 

Six different compounds of salt were used in this experiment. Each of them was placed on the flame from a burner. Those different salt compounds emitted different colors, such as yellow, orange, mint green, red and magenta. Then, the wavelengths of the color were identified. 

When copper is put with flame, we can see a mint-green color. The wavelength corresponding to that color is about 5000 angstroms.

Nonetheless, this experiment was not conducted perfectly. One possible source of error can be from the way the color was observed. Color is something that is subjective. This would lead to inaccuracy in the wavelengths of chemicals identified. To avoid this error, a colorimeter can be used to accurately measure the wavelength.  


Unit Circle | Math

As SAT test date is approaching, I practiced both the math and verbal section frequently. A topic in SAT that I learned was the unit circle. This topic is a foundation to the idea of calculus. I’ll be taking pre-calculus class for the rest of the school year so this will be helpful.

A unit circle is a circle with the radius of 1. This circle helps us understand and calculate the angles and lengths of special triangles — 30-60-90 and 45-45-90 triangles. In other words, the unit circle is made up of special triangles.

Below is a drawing I made that explain unit circle.

Greece and Rome Influence our Modern World

In literacy class this term, we studied ancient civilization because in order to develop a society, we should look back at the societies in our history. One big thing we investigated is how there are many aspects of today’s world that derived from Greece and Rome. Below is an excerpt of my DBQ essay I wrote regarding the influence Greece and Rome have on the modern society.

Modern society is encompassed with entertainment and procedures that contribute to the convenience of everyday lives, but where did the ideas for the creation of modern society emerge from? In fact, the inspiration for modern society is rooted from Ancient Greek and Roman society. Many aspects that were practiced by ancient Greeks and Romans are something that’s practiced by modern citizens. The two main ancient societies had greatly influenced the development of current politics, entertainment, and medicine that are indispensable for a society.

Greece and Rome are well known for their government system and how they’re influential to that of today. Often, the politics of Western nations remind us of the democratic system, democracy, of ancient Greece and Rome. Based on Document 5, Greek society was the first to implement democracy into their government, and Rome took this political system to the next level. Athenian democracy allowed their citizens (only males) to shape their government, including voting. According to National Geographic News, election procedures and the justice system of America were influenced by ancient Greece. Additionally, Rome developed democracy to form a better government structure: they sparked the idea of “elected officials.” These people had the equivalent role a president or a king has in a country nowadays. They had control on defense and consider any dilemmas for the countries. Another fact is that Rome emphasized the value of citizen participation in the government and we can see that in Document 1: Pericles said, “we do not say that a man who takes no interest in politics is a man who minds his own business; we say that he has no business here at all.” This fact could remind us of many modern countries that mandate their citizens to serve in the military field. Here, one can see that the archaic Greek and Roman civilizations bring forth the legislation and authority that is still practiced in America and many other countries in present days.


How Ant Man Still Has His Super Strength When He’s Small

In physics class, we had a fun and challenging project, which we researched the physics behind a superhero of our choice. So, learn why Ant-Man still has his super strength when he’s small with my writing below!

Dr. Hank Pym invented a suit that allows someone to shift size: to the size of an ant. He did so by using the Pym particle to create the “reducing serum.” The suit is made out of “unstable molecules and steel mesh.” Ant-Man gains his size-shifting superpower from this remarkable suit. This super suit is capable of reducing size, while remaining typical human strength. But there are something about it that’s far from reality.

Square/Cube Law

Galileo created this law, which states “When an object undergoes a proportional increase in size, its new volume is proportional to the cube of the multiplier and its new surface area is proportional to the square of the multiplier.” In simpler words, if an object increases its size by two times, the volume would be eight times greater and the surface would be four times greater. This works the same way when an object shrinks: the volume would be eight times smaller and the surface would decrease by four times. This law also tells us that the strength associated with area and the mass associated with volume.

So if Ant-Man becomes the size of an ant, his area and volume would decrease accordingly. This would mean his strength and mass would diminish drastically! Since force link with mass, where did Ant-Man get his force to punch someone that’s greatly bigger than him when he’s the size of an ant? That’s quite far from reality. But if he breaks the Square/Cube Law and had his human-size mass, he would be able to maintain the force. That brings us to another problem. If Ant-Man has the same mass with a smaller volume, all the atoms would be compressed in a small size. He would be so dense that he would sink to Earth.

Then, how would that be possible?

Higgs Field and Pym Field

Higgs field is the reason objects in the universe have mass. If an object experiences a harder time going through Higgs field, it has more mass and less difficult means less mass. If we can change that difficulty (changing the strength between the object and the field), we can change the mass.

On the other hand, we are able to change the strength between an atom and Pym field (discovered by Pym Hank in the Marvel comic), therefore, change the size of an object. But It’s difficult to shift size because we can’t easily remove or add atoms. We don’t know where would those atoms come from or go to, and how would we ensure that it will come back together when we want to get back to the original size.

The comic recommends that those atoms can be stored in the Kosmos dimension. Another suggestion would be to modify the constant that controls the size of an atom. For example, Planck’s constant, which determines the radius of the atoms, can become 10 times smaller, making the radius of the atom 100 times small. The radius is only one dimension of an atom; if all dimensions become smaller, the size would become millions of time smaller, according to the Square/cube law. However, the mass would remain the same, making Ant Man’s body really dense.

So, what would make it possible?

Cross-interaction between Higgs field and Pym field

In order to make that happen, Higgs field and Pym field needs to work together to reduce the mass and size, respectively. So if the mass decreases, the size would also decrease to remain at the same density, but that would cause less strength. So when he needs to use his force, for instance when punching, Higgs and Pym field would have to disconnect. This means he could momentarily gain his original weight, and therefore, exert the same amount of force as he was his normal size. How Ant-Man can connect and disconnect between the two fields might have to connect with Kosmos dimension and Quantum Realm, where atoms can be stored.


Women in STEM | Rachel Carson

Women in the STEM fields are usually ignored, and it is very important that we acknowledge them as we approach gender equity. As we heavily studied gender equity this term, in physics class, each of us researched about a woman in STEM of our choice. I chose to research about the influential Rachel Carson. Find out more about her with my writing below!

Silent Spring, the environmental science book about the negative effects of pesticide, was published on 27 September 1962. Rachel Louise Carson was the author of this book, and many other famous ones including The Sea Around , The Edge of the Sea, and Under the Sea Wind.

Carson was meant to be a writer; she started writing at a young age and won her first prize when she wrote her story for the St. Nicholas Magazine at the age of 11. As a teenager, she attended the Parnassus High School, and proceeded to Pennsylvania College for Women (Chatham University). With full scholarship, she shifted her major from English to Biology.

After succeeding University, Carson began her teaching career. In 1930, She taught zoology at Johns Hopkins Summer School. Later on in 1931 to 1932, she taught at the Dental and Pharmacy School, University of Maryland. She aimed to pursue PhD at Hopkins Marine Biology, but due to lack of finance during the Great Depression, she abandoned school.

To earn financial support for her family, Carson wrote 52 radio programs for the series “Romance Under the Waters.” In 1936. She was employed by the Bureau of Fisheries in the Department of Commerce as a junior aquatic biologist. At the same time, she started freelance writing and earn minor income.

Between mid 1930 to early 1940s, Carson has written articles and a book. In September 1937, she published her article “Undersea” in Atlantic Monthly. In between 1938 to 1939, she worked on her book Under the Sea-Wind. In the following years, Carson had written many papers and articles to many publishers, some of which are turned down.

In 1958, she started her book Silent Spring. This particular book was inspired by her friends from Duxbury, Massachusetts. This friend wrote a letter to The Boston Herald regarding the concern of bird dying because of pesticide spraying. She sent a copy of the letter to Carson.

Silent Spring took four years to complete. It included examples of adverse effects of DDT on the environment. Rachel Carson criticized the United States Department of Agriculture for spraying pesticide to kill fire ants. She stated they didn’t consider the negative effects it has on the environment. This book is a big accomplishment for her as well as the environment of the US. The government banned DDT because of her book. In addition, the creation of the Environmental Protection Agency was because of Silent Spring. On August 1962, this book was recognized by President John F Kennedy in his speech.

At the age of 57, Rachel Louise Carson passed away due to breast cancer.



What Does a REAL Man Mean to You?

In literacy class, we had a project to write an article about any topic ralating to gender equity. My article include different perspectives of female on what a real man should be like.

When we think of a man, we often think of masculinity. But are all men masculine? Or do they need to be masculine?

That’s the way many men think about how they should be. This is not necessarily what girls and women think.

I asked a question to several females I know, ranging from Asians to Westerns, and from 15-year-old teenagers to a 30-year-old woman. The question is “What does a real man mean to you?”

Very little of the responses claimed a man needs to be strong! In fact, many think a real man is much more than just their appearance.

“If a person identifies himself as a man, he’s a real man,” Vornsar Ses, my close friend, mentioned. Similarly, Samantha Cody, a learning facilitator at Liger wrote to me, “I would say, my idea of a ‘real man’ is: a person who wants to be called a man. Pretty simple, but that’s about my only standard–you’re a “real man” if you identify as a man, nothing more required or expected of you.” The same idea is said by Cara Shelton, another learning facilitator, “… a real man must want to identify as a man.”

Some said to be a real man, you just need to exist!

“He should physically exist!” Sreynith Sam, another friend of mine, briefly said.

Despite those simple requirements, there are some characteristics an ideal man should have. Cara genuinely expressed, “there is not much more ‘real’ a man needs other than existing. However, I would be lying if I said I didn’t have certain ideas of an ideal man or “real man” in the colloquial sense.” She continued, “he sees and treats women as equals and acknowledges that the expectations and roles we all participate in are socially created and not natural because of our sex. He applies the traditions or practices of being a “gentleman” to all people and all manners of his life.”

Alice Dimitroulis, a teenage girl from Australia, indicated, “for me, a real man doesn’t necessarily have to do with physical appearance. I understand the term itself is sometimes used to challenge a man’s confidence, for example ‘you’re not a real man if you can’t lift those heavy weights.’” She went on to say that a real man should be honest with himself, doesn’t fall into peer pressure, doesn’t worry about being the best and doesn’t take offense when others say he’s not a real man. Likewise, Cara remarked, “A real man is not threatened by successful, powerful women.”

A Korean teenager, Soyeon Lee, responded that there are a few aspects of an ideal man, “for me, ‘real man’ is [someone] who is good at his own area such as debate, sports or math(ability), a warm hearted man(personality), and can be looked nice at least to me(appearance).” Comparably, one of my friends feels that a real man is someone that “people can depend on, learns from his mistakes, does what is necessary, could make people around him smile [and] respectful”

Respect and appreciation are also essential ingredients for a real man. Many said they should admire others around them, especially women. Sreynith believes a real man is “a man who respects women and does not humiliate them.” Another friend of mine commented, “He’s grown up and respectful. He should be a feminist, not going against anyone. He should be a wise man to be a real man.” Cara made a few other points about different aspects of appreciation, “a real man is not homophobic. A real man tries to avoid language that is offensive and stereotyped. A real man can appreciate and admire female beauty while also controlling himself and remaining loyal (if this has been decided in a relationship).”

I’ve been communicating other women’s perspective of men, but I haven’t revealed anything about my idea of a real man. An ideal man to me is all of the above. I know that a man can’t be all those things, so to me, the most important characteristic is that a real man is able to show his emotion when necessary. Even though many people consider this expression as weak, it’s not in my opinion. I clearly remember a statement and fell in love with it ever since. The statement was made by Arn Chorn pond, the founder of Cambodian Living Arts, and he said, “it takes a real man to cry.”

I’m clearly aware that different people have different views of what a real man is like. Our opinions on a real man might be different from those of our best friends, or parents and grandparents. There is no one definition of a real man. Everyone of us needs to acknowledge this fact and encourage men to be whoever they want, regardless if they fit in your definition of a real man.

AP Statistic Response Practice

The AP Statistic exam is in about four months, so part of what we do in class is practicing writing response for the actual test. Below is a sample question and my response to it. (a). The scatter plot support the newspaper report that states the more semesters needed to complete an academic program, the greater the starting salary in the first job. The scatterplot shows a moderately positive linear association, meaning the more semesters needed to complete a program, the more starting salary earned.

(b). The slope of the least-squares regression line is 1.1594. This means for every additional of semester needed to complete a program, there will be an addition of about 11,000 euros to the starting salary.

(c). For the business majors, the scatterplot shows a strong negative and linear association between the number of semesters and starting salary. This means the more semesters needed to complete an academic program, the less the starting salary earned.

(d). The median starting salaries vary among the three majors. Business majors have the lowest median starting salaries in thousands (36-38), followed by physics majors (48-50). Chemistry majors have the highest median salaries in thousands (54-56).

(e). Based on the analysis of the independent researchers, the newspaper report could modify to say that within each major, the more semesters needed to complete an academic program, the lower the starting salary earned in the first job. The major with the highest starting salary is chemistry, followed by physics and then business.
