It is said that oil and water do not mix. This phrase is also used to describe two people who do not get along and cannot even stay near each other. But technically speaking, oil and water can be mixed. When you mix oil and water, you will find that droplets of oil float in the water. If you add an emulsifier (something that helps emulsion – the mixing of oil and water – such as soap or egg white), the oil droplets break down into very fine droplets that spreads through the water to make a stable emulsion fluid. Thus, even something like oil and water that appear to never mix can be mixed using science. Not only that, but some foods that we enjoy so much such as mayonnaise, milk and vinaigrette are all emulsions. Two fluids with different densities and properties, never wanting to be together, can combine to form such a great mixture.
If two people who never get along and refuse to mix were to congeal like mayonnaise, they may form a surprising combination, producing synergy.
Phones, golf clubs, scissors, forks and knives, the order of writing… Almost everything in this world is made for the convenience of right-handed people. Because of this, there is a hypothesis that left-handed people have a relatively shorter life expectancy compared to right-handed people.
Dr. Diane F. Halpern of California State University conducted a research comparing the life expectancy of right-handed people versus left-handed people. The results were astounding; the mean life expectancy of right-handed people was 75, while left-handed people only lived 66 years on average. Dr. Halpern posited that this was due to left-handed people becoming stressed living in a right-handed world, shortening their life expectancy. Of course, there were debates about whether the results were reliable or not and there was heavy opposition from the left-handed community. But if the left-handed people are enraged about being discriminated against by society, this would stress them out and actually shorten their life, so it might not be best not to debate about the issue.
Left-handedness has historically been associated with evil. The word right also means “good”, while left-handedness is formally known as sinistrality, which shares its etymological origin with sinister. The word for right is associated with good things throughout the world, while left is associated with bad things. In Korea, 오른 (oreun, right) has the same pronunciation as 옳은 (orlheun, true)“. The Chinese character for left (左) is also used to mean “improper”. In medieval Europe, left-handed people were thought to be associated with the devil or witches and were often executed. Left-handed people have been unjustly hated throughout time and space.
During the 11th century, the town of Coventry was suffering grievously under the earl’s oppressive taxation scheme. The earl’s wife, Lady Godiva, took pity on the people and pleaded her husband to lift the heavy taxes. The husband refused over and over, until one day in exasperation he made a wager: if she would ride through the streets of Coventry naked, he would grant her request. The earl believed that she would never undertake such a shameful, scandalous act. Lady Godiva pondered on the decision for a while, but then agreed on the condition that her husband keep his word.
Rumour quickly spread of what Lady Godiva was willing to do for the sake of her people. Out of respect and appreciation, the people of Coventry mutually agreed to stay indoors behind shuttered windows to preserve her dignity as she passed. On the fateful day, Lady Godiva set out on her white horse, stark naked and only draped by her long luscious hair. The entire town was silent, with every person in their home with the windows closed shut so that the Lady was the only one passing by, with no one to see her. However, one man, a tailor by the name of Tom, could not overcome his curiosity and lust and decided to peep through a hole in his shutter to gaze at her nude body. At that moment, he was struck blind, being punished for his voyeurism (this is the origin of the term “peeping tom”). In the end, the earl reluctantly abolished the onerous taxes, admiring his wife’s bravery and the respect the people had for her.
In human society, there are many ways for a person to interact with others when in a group setting. Some may choose to be selfish and only be out for their best interests, while others may choose altruism and cooperate with each other. The mathematical model that tries to predict human behaviour and outcome in these settings is the Prisoner’s Dilemma – the core of game theory. Tit for tat is one strategy that can be employed in such a setting.
The basis of tit for tat is equivalent exchange. A tit for tat player always chooses to cooperate unless provoked. As seen in the Prisoner’s Dilemma, if both players cooperate, both benefit (let us say 3 points each); if one player defects, that person gains more than from cooperation (5 points) while the tit for tat player gains 0 points.
If a tit for tat player is provoked, that player will retaliate. However, the player is also quick to forgive. Ergo, if the other player chose to cooperate, the tit for tat player (following the principle of equivalent exchange), will also cooperate. If the other player defected, the tit for tat player loses the first round and then chooses to defect from then on.
Note that tit for tat strategy only works when there is more than one game so that the player has a chance to retaliate.
Let us use an example to illustrate why tit for tat strategy works. In this scenario, two tit for tat players and two defectors all play six games each, using the above point system (if both defect, they each receive 1 point). The results are as follows:
Tit for tat vs defector: Tit for tat loses first round, both defect for next 5 rounds (5 vs 10)
Tit for tat vs tit for tat: Both cooperate on every round (18 vs 18)
Defector vs defector: Both defect on every round (6 vs 6)
When the points are added up, a tit for tat player gains 28 points (5 + 5 + 18) while a defector only gains 26 points (6 + 10 + 10). This is a surprising turn of events, as the defectors never lost a round and tit for tat players never “won” a round. This goes to show how cooperation leads to better long-term results while selfishness prevails.
There are shortcomings of this strategy. If there is a failure in communication and one tit for tat player mistakes the other’s actions as an “attack”, they will retaliate. The other player then retaliates to this and a vicious cycle is formed. This is the basis of many conflicts ranging from schoolyard fights to wars (although interestingly, tit for tat strategy is also found during wars in the form of “live and let live”). One way to prevent this is tit for tat with forgiveness, where one player randomly cooperates to try break the cycle (a defector would respond negatively while a tit for tat player will accept the cooperation), or the tit for two tats, where the tit for tat player waits a turn before retaliating, giving the opponent a chance to “make up for their mistake”.
Computer simulations have all proven that tit for tat strategy (especially the other two types mentioned just before) are extremely effective in games. In fact, it is considered one of the most optimal strategies in overcoming the Prisoner’s Dilemma.
In human societies, there is usually a mix of “nice people” and “selfish people”. By cooperating and trusting each other, we can produce a much greater gain over time compared to being selfish. And since society still unfortunately has “defectors”, you can retaliate to those who refuse to cooperate by defecting on them also. Ergo, a good approach to life is to initially reach out your hand to whoever you meet and treat them from there on according to how they respond. If they take your hand and want to cooperate, treat them with altruism and help them out. If they swat your hand away and try to use you for their selfish gain, it is fine to shun them and not help them out.
Through cooperation, understanding and connection, we can build a far more productive and efficient society, just like the ants.
Travelling is fun. But strangely, the etymology of the word travel is the Latin word tripalium, which means “torture instrument”. This is most likely because in the old days before airplanes and trains were invented, travelling was often long, arduous and painful. Travelling is probably the least terrifying form of torture. Let us explore the various methods of torture used throughout human history. There are many types of tortures, but they can be largely divided into physical and psychological torture. The main goal of torture is to induce maximum pain to extract information from, punish or to execute a person.
Physical torture is very simple: inflict as much pain as you can. For example, you can simply tie the person to a chair and beat them senselessly, or apply pressure to a wound to cause intense pain. A useful tip for beating someone is to place a phonebook on their stomach or hand and hitting the book, which transfers pains while not leaving a bruise or any marks. A simple way to cause extreme pain is the use of fingers. Finger tips are extremely sensitive and contain many nerve endings, meaning sticking needles under the nail bed or ripping the fingernails off causes extreme pain. Like this, medical knowledge has often been used to develop new ways to torture people. For instance, heating the sole of the feet with fire causes severe pain, electricity used in the right amount can keep the person alive while causing pain and seizures, and if you lie a person flat and on a slight decline (so the head is lower than the body), put a cloth over their face and pour over it, you can induce a sensation of drowning (this is called waterboarding and is used by the CIA). Another simple, effective torture method is the joori-teulgi(주리 틀기) from Korea, where a person is tied to a chair with the feet bound, with two long sticks inserted between the thighs, crossed, then pulled down to streth the thighs apart. This causes extreme pain and suffering.
As mentioned above, torture can be used to kill a person too. The famous hanged, drawn and quartered torture was used in the Middle Ages to punish treasonists. The convict was drawn behind a horse for a while and then hanged until just before death, when they were disembowelled, beheaded and quartered. Another strange, complicated method of torture can be found in China, where slow slicing was used. Slow slicing involves tying a convict to a post and cutting slices of flesh off him until he dies. Executioners often had an art of slicing in such a way to prolong the suffering for as long as possible without killing the person. Another execution method found in both Western and Eastern history is dismemberment by horses, where the person’s four limbs and head are tied to individual horses (or cows), which are then made to run in different directions to violently rip the person up.
Animals were used in various forms of torture throughout history around the world. Tying the prisoner to an elephant’s feet to crush them to death, putting a rat on the person’s stomach then putting a pot over it and heating it with fire to make the rat burrow into the person’s guts, feeding them to lions or vicious dogs, coating them in honey and leaving them in the path of fire ants to make them get slowly eaten… Out of all of these, the most bizarre method is the goat torture used in ancient Rome. This torture involved tying the prisoner to a chair and securing their feet, which were coated with salt water. Next, goats were released around the prisoner. The goats would lick the sole of the feet to cause tickling, which over a prolonged period is interpreted as pain by the body. This eventually drives the person insane from pain.
Unlike physical torture, psychological torture induces shame and fear rather than pain. Threatening, solitary confinement, sleep deprivation, rape and sexual torture, sensory deprivation, exploitation of phobias, loud noises (such as banging on a door constantly), blindfolding the person and rubbing a balloon on their cheeks, placing foreign objects or snakes in the anus or vagina, leaving them in a container full of insects… Psychological torture has just as much a variety as physical torture and can have longer lasting effects on the person. Furthermore, as it leaves no external marks, it is still frequently used in the modern day.
No matter what the method, inducing extreme pain to control people, extract information and cause suffering is an inhumane act that cannot be tolerated. If mankind had focussed their creativity and effort into more constructive and altruistic things rather than discovering various ways to cause pain, we would probably be living in a much better world.
We laugh when we are happy. Laughter provides us with happiness and is the best medicine available to us, relieving the pain and stress of life. In fact, when we laugh we secrete a neurotransmitter called endorphin, which as the name suggests (endo(inside) + morphine), has the same properties as morphine.
What makes us laugh? The best theory to date is that laughter is an instinctive response to the passing of danger (also called the relief theory). For example, if our ancestor came across a predator but it passed by without noticing him, he would have laughed in response to the relief he felt. Others would see from his laugh that the danger had passed and laugh also (possibly explaining why laughter is contagious).
This theory also explains why humour makes us laugh. When you throw a joke, you are essentially giving the other person a “cognitive riddle” with a logical inconsistency. This inconsistency causes the recipient’s subconscious to become confused: “Why is it funny? Why can’t I understand it?”. As jokes are fundamentally a “surprise” to the other person’s mind, they try to solve it and figure it out whether it is a danger or not. If they get the joke, the inconsistency is solved and the person feels relief (as it has been revealed that the confusion brought on by the inconsistency was not dangerous). Once the confusion passes, the person laughs in response. But if the person does not get the joke, the “danger” has not passed and the person does not laugh. This is the basis of one of the laws of comedians: “if the audience is confused, they do not laugh”.
Laughter is beneficial for your health. Frequent laughter lowers the blood pressure, boosts the immune system, relieves pain and lowers the levels of stress hormones such as cortisol. Laughter is especially good for your mental health, therefore having a five-minute laughter yoga session every day where you just laugh as hard as you can will help you lead a happier life. However, ironically laughter can kill you too. Cases of “death from laughter” have been recorded since ancient Greek times to the modern day. The cause has not been identified but it is known that intense laughter can cause cataplexy, which is a paralysis induced by extreme emotions. It is possible that intense laughter overloads the nervous system and causes a heart attack.
A “good fortune teller” is not an “accurate” fortune teller. A “good fortune teller” is a fortune teller who “says good things”. A fortune teller who tells fortunes that are too real, despite warning people of the dangers to come in the future, tends to be ignored and hated on just like Cassandrafrom ancient Greek mythology. Human beings say they fear uncertainty in the future and want some certainty, but they do not want to hear about an unhappy future. This is a normal response. Who would want to hear that they will soon be diagnosed with a terminal illness, or that they will break up with their lover? However, people are fascinating in that they still try to know the future. We go to fortune tellers and read horoscopes to try figure out what will happen to us. But if they receive bad news such as “you will fail your next exam”, instead of studying even more they curse at the fortune teller for giving them a bad prediction. Thus, human beings live among curiosity about their life and fear of the unknown future, while celebrating good fortunes and actively denying bad ones.
The reason why we like to have our fortunes read is similar to why we watch previews of television shows: we are curious about what will happen. But if you ponder this deeply, you soon come to a great epiphany. The further you look out into the future, the clearer this becomes. Everyone eventually dies. A person’s life span is typically not much longer than a hundred years, with everyone meeting the same fate some day.
A fortune teller predicts the ups and downs of a person’s life. If you think about it, life is composed of a series of peaks and troughs that eventually result in death. No matter what misfortune comes your way, it will pass just as seasons come and go. A person who passed an exam is happy and leads a good life, but even if the person fails, they somehow make it through. Unless you give up, a person will continue to live on. C’est la vie. Life is as simple as that.
If the best fortune teller in the history of mankind told your fortune, they would say the following: “nothing matters, live the way you want”. Whether your fortune for the week is good or bad, you will eventually die. There is no point scaring yourself with fortunes, live every day as if it was your last. An uncertain future may be scary, but it also represents infinite possibilities. Just like Schrödinger’s cat, our tomorrows are both alive and dead at the same time. Until tomorrow comes and the box is open, we can never know what the future holds.
So as long as it does not harm you or anyone else, do whatever the hell you want.
The Taegeukgi is the official flag of the Republic of Korea. It was chosen as the official flag of Joseon by Emperor Gojong in 1883 and has been used as the flag for South Korea since 1948. The Taegeukgi is an extremely symbolic flag that expresses the values and ideals of the Korean people while also containing the sorrow caused by the great tragedies in modern Korean history: the 36 years of Japanese colonisation and the Korean War. Even before Korea was founded, the flag was used in protest of the Japanese Empire and for the independence of Korea (especially in the famous March 1st movement). Much like Hangul (the Korean alphabet), the Taegeukgi, designed by Park Young-hyo and commissioned by Gojong, is a very scientific and mathematical flag. Let us analyse each part of the Taegeukgi.
The Taegeukgi is composed of a red and blue taegeuk symbol (“yin(eum)-yang symbol” is technically a misnomer) on a white background, surrounded by four black trigrams (4괘, sa-gwe). The white background symbolises brilliance and purity and the Korean people’s traditional love for peace. The taegeuk symbol symbolises the harmony of eum(blue) and yang(red), an imagery of the interaction between the two extremes and the natural rule of continuous generation and progress seen in the universe.
The trigrams in each of the four corners is called geun gon ri gam (건곤리감, 乾坤離坎) in order and each trigram symbolises a certain characteristic of everything in the universe.
Geun (three lines) symbolises the sky, spring, metal (geum, 금, 金) and humanity (yin, 인, 仁). Gon (six lines) symbolises the earth, summer, earth (toh, 토, 土) and righteousness (eui, 의, 義). Ri(four lines) symbolises the sun, autumn, fire (hwa, 화, 火) and courtesy (ye, 예, 禮). Gam (five lines) symbolises the moon, winter, water (su, 수, 水) and intelligence (ji, 지, 智). The taegeuk lies in the centre of the four extremes in each each corner to establish an infinite harmony and balance.
As you can see, the taegeuk is far more scientific and deeply philosophical than simpler flags such as those symbolising the Sun God (Japan), the number of states (USA) or a composite of three different flags (UK). It is the ultimate flag that prides the Korean people’s wisdom and advanced culture.
What is the typical look of a human being? The following is a character bio using data of the most common traits and average statistics from the world population.
The typical model of Earth is a 28 year old Han Chinese male called Mohammed Lee. His height is 1.75m, weight 80kg, he has black hair and brown eyes and he is right-handed. He speaks Mandarin Chinese and his religion is Christianity. He works in a factory earning less than USD$12,000. He owns a cellphone but not a bank account. The following is the most typical face constructed using a composite of 190,000 faces of people fitting the above description.
The Chinese have always deemed Korea as the country of courteous and well-mannered people (동방예의지국, 東邦禮義之國). An ancient Chinese historical text called Shanhaijing(山海經) states that the people of China referred Korea as The Courteous Country Of The Rising Sun In The East or The Country Of Gentlemen. Confucius once said that it was his dream to even take a raft to Korea to learn more about etiquette. They always held Korean people in high regard, complimenting to no end with descriptions such as “righteous people (仁人)” and “they like to decline politely and do not fight”, or “as they do not steal from each other they do not keep doors locked, and the women are virtuous and trustworthy and not lewd”. In short, Korea was respected as a civilised, advanced culture throughout the ages.
