The Ant And The Grasshopper

Posted on by Jinavie

Once upon a time, there lived an ant and a grasshopper in the forest.
In the hot summer, the ant worked hard under the burning sunlight.
But the grasshopper spent all of his time playing on his instrument and having fun instead of working.
The ant was envious of the grasshopper, but on the other hand he pitied him.

One day, the grasshopper asked the ant: “You should rest a bit. It is important to work hard, but you should also think of your health.”
The ant, in a fit of rage, said: “You have no right to say that. The summer will not last forever and there is a finite supply of food in the forest. If you do not work hard now to gather food, everyone else will take it and you will die in the winter. To be happy in the future you must endure the pain of the present. I worry for your future.”
“If you have to live a hard present for a happy future, what meaning does your life have? Food does not define happiness.”
“That is just wishful thinking of the poor. A day will come when you will pay dearly for your lack of reality.”

And time passed until winter came. The winter brought a merciless cold snap and the forest quickly froze over.
The ant was right. The grasshopper – with no food or shelter – could not fight the cold and soon froze to death. As his body became more and more rigid, he thought to himself: “Well, I enjoyed my youth and had a happy time, so I have no regrets at least.”

The ant had enough food stored up and so he could live in his burrow without starving to death.

In his cold, damp, dark burrow he spent a lonely time, extending his miserable life just a little bit longer.
After a month of enduring it, he could not bear the continuous cold and eventually froze to death.

All is vain in the face of nature. Instead of just worrying about the future, one must also invest in the past and present to lead a complete life of happiness.

Confidence

Posted on by Jinavie

Two psychologists, Bob Josephs and Pran Mehta, performed an interesting experiment studying the how extroverted and introverted people react differently to a rigged game. They told a pair of participants to play a game where they had to draw lines to connect numbers in sequence as they popped up in a grid. They also told them that it was to study their spatial awareness and intelligence. The pair were given the game in a competitive setting at the same time so one could tell if they were “winning” or not.
The grid could be easily rigged to determine who would win. Josephs and Mehta posited that men and women with high testosterone levels would have high confidence in their spatial awareness, while those with low testosterone would be the opposite. 
What they found was quite interesting.

When those with high confidence in their abilities lost a game, they were more distressed relative to when they won (as measure by their cortisol, a stress hormone, level). Those with low confidence were more distressed when they won a game.
Furthermore, after winning a game these participants would show a fall in their ability to reason and solve logic problems. 

The reason behind this perplexing result is likely to be a cause of “mismatch”. It has been hypothesised that human beings are very protective of their self-identity and when this is challenged, they try stubbornly to rationalise their identity even if it means a negative outcome. For example, a person who believes they are not creative will dress and act to show this trait, even if it means others will see him in a negative light.
In the case of the game, the participants were confused as they won the game when they believed they would do badly. 
This same effect has been found in studies looking at pay raises. Those with self-esteem issues are less likely to be satisfied with a raise as they feel that “they do not deserve it”. They are also more likely to quit after a raise rather than before. It is quite possible that this would also apply to students with low self-esteem, as they would expect lower grades and (subconsciously) actively achieve lower grades to satisfy their self-identity.

Forecast

Posted on by Jinavie

When the weather forecast says today will be sunny, it always seems to rain (and vice versa). In fact, according to a US study, forecasts are sometimes less accurate than flipping a coin. If not even professionals can accurately predict the weather, can ordinary people like you and I do it?
The key to this is observation. By carefully studying your surroundings, you can look in to the future.

There are many signs before rain comes. For example, if the sunset is unusually clear or if a mountain far away looks smaller or hazy then it is very likely that it will rain the next day. If you see a rainbow in the morning it suggests rain is coming from the west. On hot days without any wind, it is likely there will be a heavy shower.
Animals are also adept at telling the weather. Frogs crying, worms coming out and swallows flying low are all signs that the air is humid and rain is coming. Swallows are especially accurate, as they fly low to catch insects that cannot fly high due to the humidity weighing them down.
If you are at the beach and there is a swarm of jellyfish, avoid going out to sea. Jellyfish near the coastline is a premonition for a storm.

If a more accurate weather prediction is required, the most precise method is cloud observation. If you study them carefully they comprise three tiers, with some clouds rising vertically.

Clouds in the highest level

  • Cirrus: Very fine, white feathery clouds that almost look combed over. If these clouds are curvy and organised the weather will be fine, but if they appear banded or spread chaotically they can gather and form rainclouds and start a shower.
  • Cirrostratus: Looks like a veil of cotton curtaining the sky. They cause halos around the sun and moon, which is a sign of imminent rain.
  • Cirrocumulus: Looks like a spread of seashells on a beach. If you find these clouds over a beach in winter, it will rain soon.

Clouds in the middle level

  • Altocumulus: Either appears as an ordered stream of rounded clouds, or looks like a herd of sheep. If these clouds shrink in size, the weather gets better (and vice versa).
  • Altostratus: Shaped like streaks of veil across the sky. They are often light grey or very dark. If they become thicker or sink to a lower level, it is a sign that the weather will be cloudy with a chance of rain.
  • Nimbostratus: The common “raincloud”, bringing rain and snow.

Clouds in the lowest level

  • Stratocumulus: Clumps of clouds that appear in layers without clear boundaries. You can see clear sky through gaps between them. If you can see clouds that were cumulus in the afternoon changing to stratocumulus by sunset, the weather will be great the next day.
  • Stratus: Looks like fog covering a low sky. If they come in the morning and disappear by night, that day will be clear. However, if they lie between altostratus and a canyon, it will rain.

Clouds that rise vertically

  • Cumulus: Fluffy clouds that you can see on a clear sky. If they disappear by evening the next day is clear, but if they can be seen late at night or float north-westerly, it is a sign that it will rain.
  • Cumulonimbus: Massive cloud pillars that rise to the level of cirrus. It always brings heavy rain and sometimes a thunderstorm.

If you know how to observe and analyse cloud patterns, you can predict the weather even when stranded on a desert island.

Optimism

Posted on by Jinavie

Contemporary artists say to the public: “Art should make people think and feel some kind of emotion. Therefore, we make provocative art to invoke the negative emotions too.”
To them, I say: “Life is ugly enough to give you those emotions every day – what’s wrong with just looking at paintings that bring out some positive emotions?”

Parents say to their children: “Why can’t you get good grades like others? Why don’t you listen? Why can’t you do anything right?”
To them, I say: “We will all be insulted plenty throughout life, do you have to criticise us even more? Can’t you give us even a few words of encouragement, something society will never give?”

Religious people say to atheists: “How can you understand true happiness without God, faith or the belief that there is heaven after death?”
To them, I say: “Knowing that I will return to nothing after a short but content life rather than going to hell for even the smallest thing simply makes me ecstatic.”

Pessimists say to optimists: “What’s so great about life? Unless you are a fool, there is nothing worth being happy about.”
To them, I say: “And that is why I try to think more happy thoughts and be nice to others. Otherwise I would never make it through this rotten world. People all have enough going on in their lives – why bother making it more difficult when you can make it a little better at no added cost? The time we have is short, so what’s the point of only thinking negative, depressing thoughts? I would rather laugh like a fool, admire the little beauty left in the world and make other people’s lives a little happier before I go.”

Everything in the world depends on your perception, so why not think positively and live happily? No matter what, we can only live a certain time, no more, no less. The key to happiness is to enjoy appropriately, learn as much as possible and to love infinitely.

Mead

Posted on by Jinavie

Both human beings and ants know how to make mead, also called honey wine. Ants use aphid honeydew, we use bee honey. The ancient Greeks called this drinkhydromeli (hydro(water) + meli(honey)). It is the same drink that the gods of Olympus and the priests of Galia all enjoyed.

Here is an introduction to how to brew mead:

Boil 6 kilograms of honey and clear away the foam. Add 15 litres of water, 25 grams of ginger powder, 15 grams of amomum seeds and 15 grams ofcinnamon to the honey. Simmer until about a quarter has boiled away, then take off the fire to cool.
When the mixture is warm, add three tablespoons of yeast and let the solids settle over about 12 hours.
Then, pour the liquid into a small wooden barrel while filtering out the residue. Seal the barrel tight and leave in a cold place for 2 weeks.
Lastly, pour the mead in a bottle, seal with a cork and wire, then let it mature in the basement cellar.

It is best to open it about two months later, maybe in time for a wild party just like the ancient Greek bacchanalia (a wild, mystic festival in honour of Dionysus/Bacchus, the god of wine, through uncontrolled drinking and orgies).

Gait

Posted on by Jinavie

In medicine, a person’s way of walking is termed gait. By analysing a person’s gait, a trained professional can gain insight into what pathologies the person may be suffering from. For example, just from the way the patient limps, the doctor may discover that the patient has an incurable degenerative brain disease.

The most common gait abnormality is the antalgic gait, or limping due to pain. Most people would have experienced the difficulty of walking with a sprained or broken ankle, muscle ache or knee problems. This is easy to spot as the patient quickly switches to the other feet when leaning on the affected leg due to the pain. Therefore, the side that stays on the ground less than the other is the affected leg.

Sometimes, you can see a person “waddling” along as they swing from one side to the other. This may be a waddling gait, also known as Trendelenburg’s gait, caused by a weakness in the hip muscles that support the pelvic girdle, either due to muscle or nerve damage. As the patient cannot support their weight on the affected side, their pelvis tilts towards the opposite side. To avoid falling over, the patient lurches their body towards the other side, causing them to waddle. Looking at the tilt and lurch gives insight into what side is affected.
Another rather common gait is the steppage gait, where the person lifts one leg higher than the other, while their foot drags on the ground. This is caused by nerve damage leading to the loss of ability to lift the foot up (termed foot drop).

As the brain controls the motor system, damage to the brain also leads to motor dysfunction. A common example is a stroke.
If the stroke damages a significant part of the motor cortex, the patient suffers from hemiparesis/hemiplegia, or weakness/paralysis of one half of the body. This causes the limbs on the affected side to stiffen, as seen by an extended leg pointing inwards and retracted arm. The patient has to swing the affected leg around while they walk as they cannot flex the hip, known as a hemiplegic gait.
If the cerebellum is damaged, balancing becomes an issue. This causes the patient to suffer from ataxia, where they cannot coordinate their movements and are prone to toppling over. These patients tend to sway violently from side to side as they try to walk in a straight line.

Lastly, degenerative brain diseases can also affect gait. There are two main examples.
In Parkinson’s disease, the patient suffers from what is called hypokinesia and bradykinesia – reduced and slow movement. This leads to a shuffling gait where the patient walks slowly by shuffling their feet in small steps. They are also stooped over and are often seen with a pill-rolling tremor of their hands – a cardinal symptom of the disease.
In Huntington’s chorea, the opposite (hyperkinesia) occurs. This causes flailing as the muscles contract in an uncoordinated manner, including both the arms and legs. Ergo, their gait is quite jerky and interrupted by bouts of flailing, termed choreiform gait, but their balance is fine so walking in a straight line is still possible.

Knowledge of these disorders may help one appreciate the suffering a patient walking along the street has to undergo everyday of their life.

Playing Cards

Posted on by Jinavie

Playing cards are the basis of so many games due to their diversity and adaptability. It can be used for any game from poker to the Eleusis game, from house of cards to magic tricks.
One thing that is often overlooked is the long history of cards and the various symbolisms hidden within. For example, the suits may have the following symbolism:

Spades            Nobility, swords, war
Hearts             Church, cups, love and romance
Diamonds    Merchants, coins, wealth
Clubs               Peasants, clubs/batons, agriculture

Although there are many debates regarding this issue, there is substantial evidence that the court cards (Kings, Queens and Jacks/Knaves) are based on historical or mythical heroes and heroines, at least for the French deck that is commonly used nowadays. The following is the list of presumed models for each card:

King of Spades                David (biblical hero)
King of Hearts                Charlemagne (great king of Franks)
King of Diamonds        Julius Caesar (great Roman emperor)
King of Clubs                   Alexander the Great (the king of Macedon)

Queen of Spades             Joan of Arc (the French heroine) or Athena (the goddess of war)
Queen of Hearts             Judith (either the biblical heroine or the tragic queen of Bavaria)
Queen of Diamonds    Rachel (wife of Jacob in the bible – he waited 14 years for her)
Queen of Clubs               Argine (anagram of regina, Latin for queen) or Hera (queen of gods)

Jack of Spades                Holger Le Danois (knight of Charlemagne)
Jack of Hearts                La Hire (comrade of Joan of Arc, member of Charles VII’s court)
Jack of Diamonds       Hector (the hero of the Trojan War or the knight of Charlemagne)
Jack of Clubs                  Lancelot (King Arthur’s most trusted knight)

Although the models for the Kings and Jacks are quite clear, the Queens are still subject to many discussions. As modern playing cards originate from France circa 15th century, the above models (official names for each card back then) appearto be valid.
This also explains the ordering of suits (spades/nobility first, clubs/peasants last, hearts/church second and diamonds/merchants third) and how the Ace sometimes trumps the King (possibly symbolising how peasant hold the power, as in the French Revolution).

Sometimes, knowing the history behind a game can make it even more fun.

Security Blanket

Posted on by Jinavie

In the Peanuts comic strip, the character Linus van Pelt is always seen with his trustworthy security blanket. What is it about a simple blanket that lets certain children feel so safe around it, and why do they become so agitated when it is taken away from them?

Psychologically speaking, the idea of attachment plays a heavy role in the child’s obsession with their security blanket (or any other comfort object, such as a teddy bear).
An infant’s perception of the world is very limited and it cannot understand the concept of “self” until it develops further. In fact, it is theorised that an infant believes that whatever it wishes, the mother (still considered by the infant as “self”) will bring it to it, thus creating an illusion of omnipotence.
When the realisation that there is something other than “me”, the baby becomes frightened. It suddenly understands that the mother and it are not one, but two separate beings. At this point, it loses the sense of omnipotence and realises it is dependent on others, creating a loss of independence.

Losing its independence and a large portion of itself (the mother), the baby becomes confused and anxious, a phenomenon paediatricians call infant’s lament. The baby tries to comfort itself by attaching itself to its first “not-me” possession – such as a blanket or teddy bear, also called a transitional object. This then allows it to be separate from the mother for periods of time. The transitional object is a reminder to the baby that it still has some control over life and some independence, which gives it comfort and allows the baby to sleep better at night (literally).
Thus, the security blanket is aptly named, as it provides the baby with the confidence and security to adapt to the new world, allowing the baby to grow and develop into a social being.

When the baby develops into a child, it develops its own sense of self-confidence so that it can detach from the transitional object. However, some children never detach themselves and the security blanket persists for a longer time. Unfortunately, this is often found socially unacceptable and seen as a sign of weakness.
Interestingly, studies show that these children are often more independent than other children, due to their ability to be less dependent on their parents. The security blanket never criticises or doubts the child’s abilities, therefore gives the child a source of infinite confidence.

Another research by Lucy van Pelt shows that removal of the security blanket from a child results in withdrawal symptoms such as fear, panic, perspiration, glazed eyes and unconsciousness within 50 seconds.

Crime And Punishment

Posted on by Jinavie

Nullum crimen, nulla poena sine praevia lege poenali. 
No crime or punishment without a previous penal law. 

This is the backbone of modern criminal law, stating that the law defines what a crime is, and without the law, there can be no crime. Ergo, a crime in the past cannot be punished with the law of the present.

The principle has allowed for many loopholes where past crimes went unpunished as they were not subjected to new laws. An example is The Homicide Act of 1957 in English law, which never gave a statutory definition of murder. This led to no less than six appeals challenging the definition, using it as a defence.
It also protects criminals by allowing them to use a defence (e.g. provocation) even after it is outlawed, as long as the crime was committed before the law came in place.

If Wonderland’s legal system was based around nullum crimen, nulla poena sine lege, then the King of Hearts would not have been able to impose his Rule #42: “all persons more than a mile high must leave the court immediately”, as he created the rule after Alice ate the mushrooms and grew in size.

Sparrow

Posted on by Jinavie

When asked “name a bird you see often”, most city-dwellers would name a pigeon or a sparrow. These two birds are the most famous urban birds that are closely associated to humans. The sparrow, being very opportunistic and adaptable, have easily taken over environments around the globe, especially those where European settlements were made. Nowadays, they are regarded as a pest due to their foraging of agricultural crop and the spread of disease. However, citizens still view them in a positive light, especially in parks or gardens where the sparrows appear to be a “symbol of nature” (ironically, they are likely an invading species driving away native birds).

One interesting fact regarding sparrows that most people do not seem to know is how to differentiate a male and female sparrow.
A female sparrow has very soft, brown feathers, with no marked features.
A male sparrow has areas of dark brown or black feathers, especially on the head and eyes. Its beak is also darker than the female.
If one observes carefully at sparrows, they can notice that the two behave slightly differently as well.
