Macet Management (TEDxYouth @BSJ)

Green wave

10 years I’ve spent in traffic and 10 years I’ve wondered “But why?” or more formally, “Why does traffic occur more in some parts of the city than others?”

I think that most TEDx talks inspire me. Actually, around 99.9% do. This may have been because all the talks I have watched was by super successful grown-ups such as Bill Gates. This time, I witnessed the Year 13s of our school give a TEDx talk. As expected, it sure did inspire me. When I walked into the theatre, I honestly sat down without expecting much, but from the beginning of the 2 hour TED talk, I was intrigued. The first talk was by Wilson Jusuf, who talked about the Indonesian traffic system and solved by question of why it is better to walk from home to school on a bad traffic day.

He argued that people tend to believe that the traffic was caused by the government’s poor design of roads and management, however he mentioned that reaction time plays a big role in this. Going back to my initial question, “Why does traffic occur more in some parts of the city than others?” reaction time helps explain a bit of this unanswered question. When a driver stops to avoid something or someone, they stop their car for a bit which makes the driver behind him stop, which makes the driver behind him stop, etc etc… It makes me think of the domino effect. So is this all related to physics because of the domino effect? Of course not. Human sciences, a study of the activities and experiences of human beings also is an area which this takes part in. How the drivers react, how cars cut infront, why drivers dont follow the lane lines. Can the WOK for this be memory? Do the drivers act this way because they remember from last time that they had to wait longer if they didn’t squeeze into small gaps inbetween two other cars? I often trust my gut feelings, so maybe they also trust their gut feelings too and they think that it brings the most personal benefit if they act so.

To create all this system of green, yellow, and red lights the programmers behind it have to use a bunch of computer science as an area of knowledge, Wilson said in his TEDx talk. Something called a green wave is a technique that occurs if a series of traffic lights are coordinated to allow continuous traffic flow over several intersections in one main direction. Reason and intuition, are both used to create this idea of a green wave. These programmers spend a vast amount of time setting these timers on the traffic lights to turn green and red when they want it to. After a long time of adapting to it, they just instantly know by intuition that they have to time this signal at this and that other signal at that. Then here comes maths, algorithms used to design these timings. It would be pretty bad if the mathematicians use faith as a main way of knowledge because hoping something will happen doesn’t really help if cars are crashing left and right. So maybe once again, reason. After hard thinking and brain storming, they come up with a reason behind all these algorithms, and test it out in a simulator before they implement it to the streets. This definately helps the crashing part of the problem.

Wilson talked about his solution which he created with his friend that included flying drones up in the air, basically as a short distance satelitte to monitor all these traffic and send signals where the traffic is occuring and where the traffic lights needs to be switched. This included all human science, mathematics, and computer science as they personally did the programming after studying the patterns of the traffic. They then brought this idea to Ahok, the governor of Indonesia to present their plans to him. They were praised however it was told that Indonesia currently doesn’t have the correct technology to bring this to the real world and out of the simulation. Unfortunate, I wanted to see Jakarta without traffic before I leave.

Then again, even after talking about all the reasons I cannot guarantee that I will understand the Jakarta traffic.

Jakarta marathon 2016

20161023_071045

23rd of October, I took part in the Jakarta marathon for the fun of it. My bad, it wasn’t fun. It definately was a new experience for me though. Even if I only ran 10 kilometers out of 42, it was something that I can look back and think “wow that was a long run”.

I signed up for the 10k run around 2 months or so before the actual run happened. I thought it would be best to go on practise runs and prepare for the marathon so I went down to the gym and ran about 5k each visit. This went on for a while until I fell ill for a week and half. A series of unfortunate events occured after this. I visited Germany a week before the marathon due to RoundSquare, and hello jetlag. Honestly, first time experiencing proper jetlag.

As expected, I got 3 hours of sleep before the D-day. I’m not trying to give an excuse, but thats an excuse. The marathon started off fairly well, running 3k just around 15 minutes, however just as we reach the 3k mark, it started raining. Younghoon kept on running but me and Simon took shelter because we didn’t want to get sick again. After some deep thinking, we thought that it would be a huge waste to just stop after 3k, not only because of the entry fee we paid, but also because we signed up for this to complete the race. The rain subsided after a few minutes so we continued running. Cliche reflection point 1: never give up.

Passing 5k, I got extremely exhausted. Sitting down was the favourable option for me at the time. I was running with Simon and without him, I would have never found the determination to keep up the pace with the other marathon runners. I’m not sure as to why I was so disencouraged to race but the next time I compete in a marathon, I’ll be overly-encouraged.

Finally crossed the line, marking 1 hour 17 minutes; a record I’m barely proud of. If anything, this will be my guide to improve my fitness (or sleep the night before). Next year, I want to cross the line in an hour, which I’m confident I can manage after figuring out how my first marathon went. To do this, I need to do more cardiovascular workouts and measure my heartrate after a certain distance so I know if I need to significatly improve my overall fitness or not.

Hashtag Never skip leg day

 

The Interview

A slow start to the year. Last month, I met with my CAS mentor, Mr Edwards to have a talk about my current progression in CAS. It was the very first interview, so there wasn’t much I could talk about due to my lack of projects.  I have only completed 1 creativity and 1 activity projects so far. Almost all of my remaining projects, I have set up and are just waiting on the right time of the year to begin.

For creativity, I’ve completed the ATL conference last month. Thats about it so far. However I have various creative projects which I am currently in part of, such as the’ Movember movement’ with the student council and ‘Rachel House- The living wall’ with a few of my friends. I’m also helping to arrange the formals which will be taking place in March the 11th, however I’m not too entirely sure if that counts as a creative project. I plan to expand on these by engaging effectively with my peers to consolidate the project until the end of it, as most of it are currently still in development. I’d like to say it covers the first 5 CAS LOs, but as far as I can tell, creativity projects really makes us work with each other, because most of our projects are student run and student based. So top 2 ‘correct’ answers would be that I have engaged in CAS LO 3: I plan and initiate, and CAS LO 5: I demonstrate collaborative skills.

What started my activity part of CAS was the jakarta marathon. I signed up to be a part of it, because it was something that I’ve never done before in my entire 16.75 years of my life (Late post-marathon blog coming soon). The marathon is one thing, but the activity that I properly set a goal for was weights. My main goal by the end of the 15 week cycle is to be able to chest press 60kg at maximum. I haven’t had a check point yet, but I’m beginning to slowly improve overtime. In my CAS mentor interview, Mr Edwards set me a pushup challenge to help improve muscle endurance. He suggested that I do as many pushups as I can every morning immediately after waking up, and I struggle. On a good day I can do upto 70 but on a good morning I can do 15.
I find recording this the hardest part of the goal because theres not really a way to prove that I’ve been practising every week. I could take photos but that wouldn’t be reliable as anyone can just take random photos and upload it onto the internet #GymSelfie.
After I reach this goal, my next goal is most likely to be squats or cardio purely because I hate running and I want to challenge myself.
The learning outcomes engaged at a significant level are CAS LO 1 and CAS LO 2. This is because I make room for improvement as I practise with heavier weights each time, and heavier weights are a new challenge to me.

C.A.Service is the most unproductive part for me. Currently its the calm before the storm since I’m yet to visit JAAN due to JAAN not being available every weekend. JAAN is an organization dedicated to help animal welfare, by rescuing and finding shelters for animals. We don’t have a set target for it yet, but I’m sure this will be one heck of a journey.
I’ll have to mention the student council once again, as I have only found out 2 weeks ago that being part of the student council executive team apparently counts as a service project. I’ll be a part of the team until the end of year 12, so my plan is to do my best to make sure all 8 of us are engaged in developing new projects within the student council which we can share with the rest of the student body.
CAS LO 6 correctly descibes service projects, are they are something that really reaches out to the world and makes a difference among lives. Along with this, I believe that service projects require a lot of respect from us, because service shouts “change” for the better. Therefore I have chosen that CAS LO 7 is definitely needed for this.

I’ve learned that theres always room for improvement in any aspect of my CAS, and theres always something to change even if it seems perfect at the time. I’ve also learned that I’m super bad at teaching children because I mentally struggled during the ATL workshops.

We have another one and half years of CAS left. I have so many ideas in my head that I want to initiate and develop after my current projects are completed, such as the Round Square community service projects that Sam, Chiara and I are planning to start during late term 2. CAS seems to improve me both physically(activity) and mentally (through service and creativity), and I’m looking forward to take part in all of that.

ATL 2016

20161028_114330

The start of the day, I was doubting myself because I thought I didn’t have the knowledge on how to work with children (11-12 years old) because for a very long time, I had a bad memory of children. But on the contrary, the Year 7s listened to me very well and followed instructions often (except for when they were being hyper active due to a massive intake of sugar from the other workshops).

My workshop was based on the ATL: Self-management for year 7s and ATL: Social for year 12s. This was a hard one because I believe that Self-management is the most important trait out of all five ATLs because it’s always easy to procrastinate and prioritize the wrong tasks over the important and urgent ones. Me and my partner Michael decided we should split work and focus on different workshops at first and combine the two after we have finished. We first brainstormed ideas on both the workshops together and then proceeded our own, I would focus on the year12 workshop and he would focus on the year7 workshop.

Worked really well! 9 year 7s attended our workshop and for 40 minutes, we played games together in between our presentation slides, which they seemed to enjoy a lot. We first broke the ice by playing a game of bang, and then we moved on to plan time table/pie charts for what they thought an average year 7’s daily life would look like. After this, we surprised them by creating our IB pie chart! Unfortunately they pitied us and said we should sleep more. 5 to 6 hours of sleep did not suit their wants for sure. After we finished our workshop, they asked if we had candy like the other workshops did. We froze for a second and looked at each other and mumbled “We don’t have candy do we…” They sighed in disappointment and instead, we gave them high fives.

The year 12 one was directly after the year 7. My close friends decided to join my workshop to ‘see’ how well I do in presenting, so I decided to make their lives harder by putting them into couples. We had 9 people in this workshop as well, so Michael joined in on the fun games. Because putting people into partners make them socialize with each other, one of our games had them explain to each other, in pairs an object, but without saying the name or what it was used for. Really fun game, but it was too easy for them. So, moving on to the next social game possible, we played bang. Again. Actually, ‘bang’ with a little twist, I’d call it. Everyone in the circle had names of someone else in the room just to make it harder for them. Everyone was confused but they seemed to enjoy it. Great success. Later on, we did the rather productive part by giving them scenarios and how to handle situations when it became socially awkward.  45 minutes passed and our day had finally ended. Thank you all for attending our workshop. We learned many things from it 🙂

I identified my weaknesses (teaching) and worked with Michael to improve upon it before we opened up the workshop. Through this experience, I am further capable of standing infront of a class and gaining their attention for over 40 minutes. Since my weakness was teaching anyone in general, this entire conference was a challenge for me. Even if I saw my friends everyday, conversing with them normally is not the same with teaching them. When we first kick started our brain storm and plans, I was mainly worried about the Year 12 one. As a former year 7, I could immediately guess that I got entertained much more easily than my current evolution. However after 26 caffeine boosts and 4190 pushups, we made it to the end of the ATL journey without any casualties. There are a few things worth mentioning to improve next time. Maybe an advice to the year below for their conference next year. To Be Able To: Attract attention for 45 minutes by figuring out a method including games and important key factors of the 6 ATLs. This can be achieved by making students set goals before the workshop, and seeing if they have achieved it by the end of the workshop.

 

 

Suns out, guns out (Activity Blog)

CA(ctivity)S.

As a part of my ACTIVITY section of my CAS, I have decided to lift heavy things across rooms in the school. Exercising is something that I have been passionate about even before the introduction of CAS. The school has basically given me a free activity that I can set a goal and develop myself to record it as a part of CAS. For this, I have chosen weights. Why? Because weights is something that anyone can pickup at any age, and set a self driven target. Also, because I hate running and I slightly enjoy the pain of Delayed onset muscle soreness (DOMS).

maxresdefault

I hope to learn proper body posture during these different types of weight exercises over the few weeks we will be doing this. For example, I would like to perfect my posture during squats or bench presses. These postures are sometimes worrying for me, as I have never had a chance to use free weights. I have used machine supported bench presses and other equipment, and I somewhat worry that it will be massivly different to free weights.

Of course, setting a goal and beating it is exciting. However, this will take time and effort to complete over 15 weeks. Over the 15 weeks, this will help me develop CAS L.O 1: Identification of my areas for growth, and CAS LO 4: Showing commitment.

Current progress:

Lido Lakes 2016

img_0466

I already don’t remember what day I had to wake up at 5 and get ready for the residential trip. Maybe It’s a bad thing that I tend to forget things very easily. As a 16 year old boy, I should worry about it but today, I’m going to worry about this blog.

The residential was action packed and had a rather busy schedule. I can recall activities such as paintball, raft building, T-shirt painting, and team building. From these, my favourite activities were the paintball and raft building. I can now say, that paintball hurts if you’re shot in the wrong spot at the wrong time. Being shot in the mouth and eating paintballs got me to multitask, running around AND getting rid the atrocious taste of gelatin like a dog marking its territory. Me flailing after getting shot made some people laugh, which is understandable, because I too, laughed at the others getting bombarded with paint.

The majority of the team building program was difficult, but what really made me struggle was the activity which required us to dribble a ball through small gaps with a cone on our faces. It seemed easy at first, but after wearing the cone, things were different. It took away 95% of my vision, and made me rely on my teammates to shout the direction I needed to swing my wooden hockey stick around. I was the first sacrifice to be made from my team, which made everyone else think I had horrible hand to eye coordination. Unfortunately for them, we all seem to have disturbingly bad coordination.

Finding new and interesting things about ourselves were the hardest part. For me, I thought I knew everything about myself but it seems like I didn’t know one aspect about me. My friend kept on waking up due to a cold during the night, and every time he woke up, he would tend to look around. The next morning, he mentioned to me that I slept in the same position for the entire night, with my arms crossed and my legs straight, facing towards the ceiling. Fascinating.

Thinking really hard, but still very difficult to find what I learned about other people.  However if I had to describe it in short, Isaac has a memory span of approximately 7 hours and Filbert likes to sleep with his shoes on.

1+2+3+4+….+∞= -1/12 ???

Why is it so hard to start off a blog post?

Maybe it’s because I don’t have much KNOWLEDGE and experience on blogs.  So far, I know that blogs are written in a conversataion style, regularly updated by an individual or a group of people. Else than this, I don’t know what I don’t know.

When I was asked about what knowledge is, I wrote “Knowledge is information, based on both the truth and the false which we use to communicate with others and enhance our abilities”. I asked the same question to papa google, it responded to me with a dictionary definition of “facts, information, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject”.  I would like to say I almost knew it, but obviously there is a latge gap inbetween the two definitions. Anyhow, my point is that people have different thoughts on knowledge and claims of knowledge. What we know now was built upon many claims made in the past. Some claims were proven to be more believable and scientific than others. The Earth is the centre of the universe. People knew that this was true until a long time of philosophical work that proved that it actually wasn’t. 

Now, time for the claims that I’ve heard in the past few weeks. 1+1=2. Thankfully, last week wasn’t my first time learning this. Everyone in the world knows that 1+1=2 but how do we actually know that this is the truth? 1+1 can be anything if we were never given the fact that it leads to 2. So technically, we BELIEVE that 1+1=2. If we were to KNOW that 1+1=2, we would be able to relentlessly rap out the complete reason behind it. Fortunately for us, someone from long long time ago has already made a 2 page explanation as to why 1+1 is indeed 2.

1+1=2?

Another mathematic claim. Okay, an actual claim this time. 1+2+3+4+….+∞= -1/12
I know what you’re thinking. This is complete garbage talk. Believe it or not, you will be so convinced that this is actual knowledge rather than just a belief or an opinion after watching this video. https://www.youtube.com/watch?v=w-I6XTVZXww
I just watched it again and I’m still so confused. Ways of knowing- many mathematical equations that seem to prove this absurd addition of numbers.

Quickly moving on to the third and final claim of the week, this time around its the knowledge claim stating that theres always 6.022140857(74)×1023  molecules in 24,000  cm3 of any gas.  I shall assess the validity of this. As a student who takes HL chemistry, I forsure know that this is a fact. However, same case with the 1+1 situation, I only know that this is a fact, I don’t know why I know that this is the fact. There are various equations and graphs behind the multiples of numbers that explain the occurance which I haven’t learned yet, only because its way too complicated for me right now.

Believing and knowing is different. Know the facts and believe in yourself *cheesy exit*.

 

The very first

2000px-Flag_of_South_Korea_(construction_sheet).svg

Hello everyone, my name is Jongwoo I have been a student at BSJ for over 6 years. I remember my very first day at school as a day of anxiety and fear, the reason mainly that BSJ was the first school that I have transferred to, so everything and everyone I’ve known were no longer relevant. I’ve quickly figured the way around the school and made a new friends. As time accelerated by, I’ve realised that nothing remains the same. Each year I would lose friends, meet new people, and have different grades. After a few years of change and 2 sets of uniform, I have finally reached last obstacle of school, IB.

On the very first morning of IB, I woke up and slithered into my blue shirt just to realise I’m no longer allowed to. No matter how hard I thought about it, I couldn’t believe that I now go to school every morning in the fancy white shirt that shouts “Responsibility”. I spent the very first hour of IB looking around the common room to get used to seeing everyone else in their very responsible uniform. Not   long after that, I had to get used to using many different acronyms such as: CAS, TOK, and ATL. The definitions were straight forward and easy to remember except for ATL (Approaches To Learning) which consists of communication, social, self-management, research, and thinking. So far, I’m confident with my social skills as well as my communication skills. I would like to work on my researching skills throughout the years of IB, but what really confused my little mind was the self-management part. It wasn’t very often that I look back to myself and sight my weak points and strengths. Few thoughts and questions later, I figured out that I wasn’t the best at personal reflection, however I believe I manage my time very well and like to keep organised. The two points seemed to contradict each other because if I was to be bad at noticing mistakes quickly, how can I keep perfectly organised? No worries me, I will figure it out by the end of the IB curriculum. ATL will always be a part of the IB curriculum, and my skills can only develop from here on.

I consider IB as the most important phase of school life, and so this is the time that I need to be the most active in. BSJ has a lot of leadership opportunities, especially this year with the introduction of the new executive student council group. I feel as if I need to do it, as leadership will be immensely important later on in the future. These opportunities are not given to everybody, so I am extremely grateful that I was given a chance to participate in conferences and international competitions which occurs annually held by or participated by BSJ.

Nothing can be certain at this point, I’ve had many aspirations for different careers which included being a chef, a football player, engineer, and many more. Most of these aspirations ended due to change of hobbies or subject preferences, except for engineering which I purely stopped being motivated because of its requirements to sit down and look at the screen 24/7 . After many unsure dreams and thoughts, I  wish to major in biochemistry or biotechnology in university, to carry on into those fields as an adult.
