Sitting on the passenger’s seat and watching my father driving, my yearning to drive grew inside me. During my childhood, I anticipated that driving would fulfill my thirst for speed and thrill. I imagined driving on a straight expressway at the maximum speed.In Korea, one must be 18 years old or older to attain a level 2 license to drive regular vehicles. The 2019 winter vacation was a suitable time to prepare for the driving license exam for me, who had just become 18 years old and had plenty of time.I had to pass three steps of exams to attain a driver’s license: written exam, driving cours

A quantum computer (QC) is a machine that uses special quantum-mechanical phenomena, such as superposition and entanglement, to quickly solve problems that would normally require repeated substitutions over a very long period of time, mainly through a process of drastically increasing probabilistic prediction. The unit of information on a classical computer is called a “bit”, whereas it is called a “qubit” on a quantum computer. The special properties of quantum particles are hard to see in the macroscopic world but become more evident in the microscopic world; protons, electrons, and atoms al

I was the club president of PoApper from last year until this summer. PoApper is a club that acts as a developer network in POSTECH where people who share an interest in software development can join to participate in seminars or projects. As POSTECH’s only software development club, we also received lots of outsourcings. Most of the time, orders were small and simple: a website for the POSTECH-KAIST Science War, a game for freshmen orientation, etc. As time passed, we received requests for larger and more complex projects. However, more often than not, those requests ended up being canceled d

Since freshmen, I have enjoyed getting involved. I filled my everyday schedule with all sorts of activities. Hanging out with friends, club activities, internships, and etc. were always of high priority. For me, POSTECH was a spectrum of endless experiences. As a true experience-centered being, I could not help but join numerous school clubs, enroll for every interesting lecture, and participate in literally every school event possible. Late-night movies in the theater, hanging out with friends, and even studying up late for exams in the library was fun. Naturally, my weekends were always load

Last fall, my book, A college student’s science books dialogue, came out into the world. The release of the book that had plagued me terribly for a year was an emotional moment. As I was contacted by The Postech Times, I was excited to talk about my book in writing, not in words, for the first time. Ironically, I started to write the book in my junior year, when my major studies were most difficult. The classics introduced in my book are books that I admired ever since I was a freshman in POSTECH: Carl Sagan’s The Pale Blue Dot, Heisenberg’s Physics and Beyond, Bill Bryson’s A Short History of

Have you ever baked a cake for yourself? I, for one, could not say I was experienced in baking. But it has been different for me ever since I stayed in the U.S. last semester. My aunt, who has been living in the U.S. for 30 years, made my sister a cake on her birthday. I was surprised as it seemed common for Americans to bake on special occasions. Is baking that easy? I felt like I should try.Once I started baking, I realized that it was simpler and more fun than I thought. Following YouTube tutorials, all I had to do was whip, mix, and chill. It was okay even if I did not have enough tools—I

When I sit in front of a computer, I always question myself: “What can I do to make the most out of this machine?” I then proceed to customize and modify my rig one by one. These start from simple tasks such as organizing my files to more complex procedures such as undervolting/overclocking the processor. There are literally millions of ways to improve your computer and squeeze every last juice out of those tiny chips. But the story does not end here; dive in a little deeper, and you will be fascinated by a universe full of imagination. A world where literally anything you imagine can become a

We come across many YouTube channels now that our generation seems to be about investing our huge chunk of life into YouTube. Unexceptionally, I also spend quite a bit of my time just binge-watching a lot of YouTube videos. There is a Q&A content where YouTubers answer viewers’ questions about their YouTube channels or themselves.Even though I have watched a lot of Q&A videos, the most recent Q&A video I watched made me feel somewhat different. I envied this YouTuber for having such explicit answers for all given questions. I imagined myself getting thrown tonnes of questions about my ambition

I wore my first bra in 5th grade. Since then, I was so accustomed to a bra that I even wore it to bed. So, when I first saw paparazzi pictures of my favorite Hollywood star without one, I was startled. Until that moment, I had never encountered or even heard of anyone who did not wear a bra when going out. However, after multiple accounts of braless celebrities, I realized that wearing a bra is treated as a personal preference in some countries and hoped to do the same if I ever travel abroad. Why do I long to be free from a bra when I was so used to it? That is because bras are uncomfortable.

Why I Chose “Start-up”.Feb. 11, 2015. I still cannot forget this day. There was the biggest 106-car collision on the Yeongjong bridge due to a heavy fog. I was regretful; I thought, “this would not have happened if we had a radar that perfectly detected objects, even in heavy fogs.” As I had been conducting research on the radar technology for 10 years, I decided to make ‘zero road accident deaths’ possible. In Jan. 2018, I quit my job and founded bitsensing. With the slogan “Design future Safety”, bitsensing is now developing technology that can ensure safety in our daily lives. Our main focu

Seventy-five years have passed since Korea was divided into two, and the reunification of our country still looks like an unattainable task. In this difficult situation, I turn to Germany, which was in a similar position as Korea in the past. In 1945, after Adolf Hitler's Nazi Germany was defeated in World War II, Germany was divided into East and West Germany. It took 28 years for the German reunification, and despite the relatively short period of division, the process of reunification and the after-effects after the reunification were significant. It is true that Korea is now in very di

After 13 years of being a student, I was tired of being one. During my first semester of being a sophomore, I discovered the Summer Experience in Society (SES), a school internship program acting as an intermediary between students and various companies, being offered every summer. I always dreamed of building my career. After much consideration and research on the applicable companies, I decided to apply for a Deep Learning job offered by Polaris3D, a growing start-up providing indoor autonomous navigation solutions. I submitted my CV and fortunately got a chance for an interview. For half an

What is a smart city and why do we need it?We are now facing one of the largest waves of disruptive changes known as the Fourth Industrial Revolution. It is expected to change almost every aspect of the way people interact with the world. The whole city is going through a major transformation as a strong wind of “connectedness” and “intelligence” blows towards the city where we live. A variety of smart devices are being introduced frequently, and they are gradually turning our living environment into a “Smart City”.Besides those personal and/or privately owned devices, we are already quite fam

On April 2, 2018, I was appointed to the position of an assistant reporter. On March 4, 2020, I will be retiring from The Postech Times. Even as I am writing this column it is surreal to imagine that it has already been two years. It really has passed in a blink of an eye. The end and closure of leaving an organization is always a sad affair. Even though I am leaving on my own accord, it is still unfortunate that I will not be able to enjoy The Postech Times reporter experience anymore.However, along with sad emotions, there is a feeling of fulfillment and happiness. During the two years, I ex

Are you an Electronic Electrical Engineering (EEE) major or interested in things related to them? If so, there’s no doubt that participating in the Consumer Electronics Show (CES) held in Las Vegas, U.S. will provide you with an unforgettable and invaluable experience. First of all, I express my appreciation for the support from the POSTECH EEE department, for providing us with a new program “Global exploration to CES 2020” for EEE junior students. The program not only gave us the precious chance of visiting CES, but also offered tours of the most popular places in neighboring regions, such as

Since young, I loved making something. I also thought that it would be great if my inventions are used worldwide. One day, I realized that “start-up” is means to fulfill all such desires. Ever since entering graduate school, I thought maybe my research material can become commercialized. One day, a friend from my laboratory suggested me to use his doctor's thesis to establish a new company and since December of 2015, we launched an entrepreneur team under the name of ORGANPRINT. Since then, commercializing ideas derived from research was always a consideration and eventually, in March of 2

When I was young, bananas were a symbol of wealth due to its high price. Only once in a while, when I sometimes suffered from sore throats due to a severe cold, my parents would buy me a banana and I would savor my each moment of it. I still love bananas, but strangely enough, it never tastes or smells good as the ones from back then. Considering this, how good would a banana taste like if it was worth 1.4 million KRW?On Dec. 2019, Italian Artist Maurizio Cattelan, or precisely his art gallery Perrotin, sold Comedian – a banana duct-taped to the wall- for 12,000 USD at the Art Basel Miami Beac

Underneath the beautiful city lights that glitter in the night sky, the citizens of Hong Kong have been battling for their future. It’s been years since the Umbrella Revolution took place, and another storm had struck Hong Kong. Now, once again the city stands in the middle of the chaos, with flames burning with desire for freedom and democracy. More than a million of people are out on the streets, fighting against the chocking hands of China around their necks.When China regained its sovereignty over Hong Kong from the British in 1997, it was under agreement “one country, two nations”, which

I like to walk. If time permits, I usually walk most places. Friends who know I like to walk avoid traveling with me. Because they know what will happen. I once went on a trip to Tongyeong with a friend. We seemed to have walked on that trip except for the time we ate. That day, my friend and I walked about 12 kilometers.Walking with friends or family is good, but walking alone gives me time to think. I used to think about my life, about my friends, or the various aspects of people passing by.I also like to walk on rainy days. Time passes and rainwater flows, but there is a person who seems to

Resolute Courage within SilenceIf someone asks me to introduce to her the most capable feminist, the first to come to mind is the students who resolutely express their opinions even while silent in class. In an ideal educational environment, everyone must feel secure, be able to express their opinions, and have the chance to actively discuss such opinions, but the real-life educational environment often has its limits. Specifically, the less the environment accommodates feminists, and the more students who voiced their opinions were cast under a spotlight, even to the point, where it seemed as
