The Donkey And The Well

Posted on by Jinavie

One day, a donkey fell in to a well. It cried piteously for hours while the farmer tried to figure out what to do. Ultimately, the farmer decided that the donkey was old and was nor worth saving. He planned to fill the well, as he had no need for it either. He invited his neighbours to come over and help him. Everyone grabbed a spade and shovelled dirt into the well.

The donkey was terrified; sooner or later he would literally be buried alive, with no food, water or air. It cried even more and begged the farmer to show mercy. The people ignored the animal’s neighing and screeching. The donkey was about to give up. There was no hope of getting out the well and soon it would die a slow, suffocating death. But then, it came up with a cunning plan. As the dirt slowly filled the well, the donkey stepped up on the mound of earth. Eventually, the mound grew high enough for it to jump out of the well. The donkey then kicked the farmer and galloped off into the sunset.

Life is bound to throw all kinds of dirt at you. But just because bad things happen, it does not mean you have to live a miserable life. When life throws a spadeful of dirt at you, brush it off and step over it instead of letting it weigh you down. With a positive mindset and determination to become happy, you can escape even when you fall into the darkest, deepest well of despair.

Five Stages Of Grief

Posted on by Jinavie

Dr. Elisabeth Kübler-Ross was a psychiatrist who was greatly interested in the field of death and dying. She believed that medical students and doctors should be aware of how important the topic was. One of her major contributions to the field of medicine was a theory inspired by her work with terminally ill patients. Dr. Kübler-Ross discovered that patients who were given bad news often reacted in a rather predictable pattern of five “stages”. She also found that these theoretical stages of coping with dying also applied to other grieving processes, such as a child going through a divorce or grieving a break-up. It is important to note that these stages are not absolutely complete or chronological, but only a general theory of how people react to grief.

  1. Denial: A person’s initial response to any bad news or trauma is usually denial. Denial is a hardwired defence mechanism of the brain to protect the mind from trauma. However, it may hinder the process of coping, with some people being perpetually stuck in this stage while never fully coping with their grief. An example thought during this stage is “This can’t be happening to me”.
  2. Anger: Once the person overcomes their denial and recognises reality, they respond with anger. This is an externalisation response where the mind tries to deal with the bad news by lashing out. It can be seen as the mind’s response to the confusion that arises from receiving the bad news, which may be caused by cognitive dissonance arising from the conflict between denial and reality. Because people at this stage often lash out with rage and verbal abuse (sometimes even physical), they may be difficult to deal with. Thus, it is important to recognise that this is a natural response to grief and try to support them even though they are acting abusive. An example thought during this stage is “It’s unfair that this is happening to me”.
  3. Bargaining: When the anger settles down, a person attempts to deal with the grief with logic instead of emotions. They will try to negotiate with a higher power to delay their death, such as through praying. This stage shows how desperate and vulnerable the person is while trying to deal with the bad news. They will try to do anything to make the grief go away, or at least reduce it. However, this stage rarely produces any viable solutions. An example thought during this stage is “If I can have a few more years, I will do anything”.
  4. Depression: With both emotions and logic failing to protect them from the grief, the person will fall into a state of depression. Hope is lost and the person understands that resistance is futile (an example of learned helplessness). By this stage, the person has become quiet and withdrawn, often detaching themselves from family and friends. Ironically, trying to cheer a person up during this stage is ill-advised. It is more beneficial if the person can pull through the depression and process it to make it to the last stage of grief. An example thought during this stage is “Why bother, I’m going to die anyway”.
  5. Acceptance: The last stage of grief is not only accepting that death is unavoidable, but also recognising that there is still time before that. The person reaches a state of clarity and comes to term with the grief, achieving some inner peace. The time taken to reach this state varies and some people may never reach it at all. It is also important to note that just because the person receiving the bad news has accepted it, others around them may not have processed the grief. An example thought during this stage is “Everything is going to be okay”.

Seven Bridges Of Konigsberg

Posted on by Jinavie

The city of Königsberg (capital of Prussia, now Kaliningrad, Russia) has the Pregel River running through the middle, with islands at the centre of the river connected by seven bridges. Is it possible to cross all of these bridges while only crossing them only once each?

If you try to solve this problem, you soon discover that it is incredibly difficult not to cross the same bridge twice. But it is difficult to tackle this problem in a brute force manner. To calculate all of the permutations in the order of bridges, you use 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040, meaning that there are 5040 possible arrangements of bridges. Then how can you prove if the problem is solvable or not?

The great mathematician Leonhard Euler, upon being asked to solve the problem, is reported to have said that the problem is impossible to solve on the spot. In 1735, he proved his answer by modelling the seven bridges of Königsberg in a diagram of four dots connected by lines (representing the bridges).

By using this model, the problem is converted into a “draw in one stroke” problem, which is also called a Euler walk to honour Euler’s contributions. Euler discovered many properties and laws regarding such problems. If a certain point is the starting point, then the line must first leave the point, then even if it comes back to the point, it must leave again. Ergo, the starting point must have an odd number of lines connected to it. The opposite applies to the ending point, where a line must enter the point, and if it leaves the point it must come back to it. Ergo, the ending point must also have an odd number of lines connected to it. In the case of a Euler walk, the starting and ending points are identical, so the number of lines is the sum of two odd numbers, making it an even number. Thus, to find out whether a picture can be drawn using one line, use the following laws:

  1. If there are no points of odd degree (odd number of lines), the starting and ending points are identical.
  2. If there are two points of odd degree, the starting and ending points are different.
  3. If there are one of more than two points of odd degree, it is impossible to draw using one stroke.

Thus, a Euler walk is only possible if there are 0 or 2 points of odd degree. Looking at the seven bridges of Königsberg problem, we can see that A is connected to 5 lines and B, C and D are connected to 3 lines each. As there are four points of odd degree, we have thus proved that it is impossible to draw a path that crosses all the bridges while not crossing any bridge more than once.

Oil And Water

Posted on by Jinavie

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.

Bittersweet Dream

Posted on by Jinavie

One still autumn night, a student woke up in tears. A teacher who found this peculiar asked the student:

“Did you dream a scary dream?”

“No sir.”

“Did you dream a sad dream?”

“No sir. I dreamed a sweet dream.”

“Then why are you crying so?”

As she wiped away her tears, the student said:

“Because that dream will never come true.”

Mother Horse

Posted on by Jinavie

Female horses (mares) exhibit a very strange behaviour after they mate with a male. A mare will mate with every other male in the stable, almost immediately after mating with the first one. This strange post-coital promiscuity does not appear to make any sense from an evolutionary perspective, as one would think that pregnancy would lead to a decrease in libido so the mother can focus on caring for her embryo. However, this promiscuity is part of a strategy that helps protect the baby horses.

It is common behaviour in the animal kingdom for a male to kill a female’s young so that he can mate with her and produce babies with his own genetic material. This also happens in horses, where stallions engage in infanticide, kicking a foal to death if it is not his. For a mother horse, this is not only heartbreaking, but also a tremendous waste of the energy she put into pregnancy. So to protect her offspring and conserve energy, she ensures that no male knows who the father of her baby is. It has been shown that males who mated with a female who gave birth will not attack the foal, as there is a chance that it is his. Thus, a mother horse guarantees the protection of her child by prostituting herself to all of the males around.

Although the story of a mother willing to sacrifice everything, even her dignity, for the safety of her offspring may be inspiring, it has also been observed that if a mare cannot mate with all of the males in the stable, she will instead abort the pregnancy. For example, if a new horse is brought into the herd after the mare becomes pregnant, the mare senses the danger to her eventual foal and proceeds to abort it. In a study involving zebras, it was found that bringing in a new male made the foal’s chances of survival fall to less than 5 percent.

Three Little Pigs

Posted on by Jinavie

The story of the Three Little Pigs is a timeless tale of how important good planning and doing things right is. Also, it serves to remind us that good architecture and engineering is key to one’s survival. A key aspect of the story is how the wolf “huffs and puffs” to blow the straw house and the stick house away. However, he cannot blow the brick house away as it is too well-built. Out of scientific curiosity, how hard does the wolf have to blow to destroy the Little Pigs’ three houses?

An experiment was performed to scientifically test this tale. The researchers built a house out of straw, a house out of sticks and a house out of bricks, then set up a fan to test at what wind speed the house was destroyed. The straw house blew away when the wind speed was 11m/s. The stick house lasted a little longer, up to a wind speed of 21m/s. Then what about the brick house? The brick house withstood winds of 35m/s, whereupon the researchers had to stop as the strong wind nearly blew the people away.

Mary Celeste

Posted on by Jinavie

In 1872, a ship by the name of Mary Celeste was spotted off the Azores in the Atlantic Ocean – completely intact and undisturbed aside from its missing crew. Not a single person, alive or dead, could be found, despite everyone’s personal belongings still sitting undisturbed where they had been left. Even little things such as valuables and piano music were right where they should have been. It was as if its crew had simply evaporated. There were no signs of a struggle and no cargo was missing. To this day, the case of the disappearing crew of the merchant ship Mary Celeste is one of the most famous maritime mysteries in history.

So what happened to the ship’s crew? Historians have been trying to figure out their fate for decades, but the question was finally solved by scientists. One fact that is known about the Mary Celeste is that of its cargo of 1701 barrels of alcohol, 9 were empty. Although an obvious answer is that the sailors went overboard with a party, the truth is even more spectacular. In 2006, Dr. Andrea Sella, a professor of chemistry at University College London, created a replica of the Mary Celeste’s hold to find out how to create an explosion without leaving a trace of fire. He simulated a leak of the ship’s nine barrels of alcohol and found that once the vapour was ignited, say by a pipe or a spark, it created a pressure-wave type of explosion. There was a spectacular wave of flame but, behind it was relatively cool air. No soot was left behind and there was no burning or scorching.

Ergo, the mystery of the Mary Celeste is most likely as follows: there was a leak of the alcohol, the vapour of which fuelled a massive ghost explosion that swept through the ship. The sailors, completely unscathed but utterly horrified, would have piled into the ship’s lifeboat without any useful things like food or water, eventually sinking or dying of thirst and exposure. The Mary Celeste would have still looked perfectly fine as it drifted the vast ocean, all by itself.

Laughter Epidemic

Posted on by Jinavie

It is said that laughter is infectious. In 1962, an extreme case of “laughter infection” happened in village in Tanzania. The phenomenon originated in a boarding school for girls. On January 30, three girls spontaneously burst out in laughter and could not stop themselves from laughing. Soon after, the whole class was suffering from fits of uncontrollable laughter. The “infection” then spread throughout the school, claiming 95 of the 159 students over a stretch of two months. This strange symptom of uncontrollable laughter lasted anywhere from a few hours to 16 days. Interestingly, teachers were not affected and only girls between the ages of 12 to 18 were affected. By March 18, the school was forced to close down due to students not being able to focus during class.

The laughter epidemic was not localised to the school. After the school shut down and the girls returned home, fellow villagers were afflicted by the laughing disease, resulting in 217 villagers being “infected” by May (mostly children and teenagers). By June, the laughing epidemic spread to another nearby school, affecting 48 girls. The epidemic then went on to claim two more schools, forcing them to close down. By the time the epidemic died down (6 to 18 months after “patient zero”), it had affected over a 1000 people and shut down 14 schools.

So what was this strange disease? Was it some new viral infection causing neurological symptoms? Was it a toxin in the water supply? The answer was even simpler: mass psychogenic illness, also known as mass hysteria. Mass hysteria is a psychological phenomenon that occurs in groups placed in high-tension situations, such as within an airplane. This setting is perfect for triggering a mass delusion, causing the person to believe they are suffering from a physical disease. The trigger is usually another “patient” and the hysteria spreads like wildfire, usually by people seeing affected victims. Although the above case makes mass hysteria look like a harmless, amusing phenomenon, psychosomatism (when the mind tricks the body into thinking it is sick) can cause symptoms such rashes, fevers, vomiting and even paralysis. In fact, all of these symptoms were also reported during the Tanganyika laughter epidemic.

Han Suk-Bong

Posted on by Jinavie

Han Suk-Bong is a famous writer from the Joseon Dynasty (Korea during 14th to 19th century), who was praised as “the master writer of the East” even in the Ming Dynasty (China during 14th to 17th century). His writing and calligraphy were partly thanks to his inborn talent, but also because of his intense training and practise throughout his life. There is a famous story regarding his training.

Han Suk-Bong practised calligraphy since a young age by himself, practising every day. The villagers all praised his talent and his mother sent him to a famous temple to study. After four years of studying, Han missed his mother so much that he sneaked out during the night and returned home. When he told his mother that he there was nothing more for him to learn, she told him to turn the lights off and said: “I will slice rice cakes while you write, then we will compare our skills”. After the two silently did their best work in the darkness, they turned the light on and it was evident that Han’s letters were all crooked and unsightly while his mother’s rice cakes were perfectly sliced in even thickness. Han deeply repented his arrogance and realised there was so much more to learn. His mother told him off and told him not to set foot in the house again until he could write perfectly even with his eyes closed, just as she could slice rice cakes perfectly. Thanks to his mother’s passion for his education, Han became one of the most well-known masters of calligraphy and literature in the Far East.

The best type of parent is one who identifies a child’s natural talents early on and helps them develop those skills. If the child becomes lost, loses their way or fall into the pit of arrogance believing they are the best, it is the parent’s duty to correct them. The moment you believe that there is nothing more to learn, you become a failure.
