Hexapod

Dragons are fantastic creatures of our imaginations, so they do not follow many of the rigid laws of natural science. They breathe unlimited amounts of fire, can endure extreme heat and they can fly despite their massive size. But perhaps the most unrealistic feature of dragons is the fact that they have an unnatural number of limbs.

All vertebrate animals on Earth follow a simple rule: they are four-legged creatures, also called tetrapods. The limbs may have devolved away such as in whales and snakes, but they remain as vestigial structures or still encoded for in the genes. Birds and bats have adapted their upper limbs into wings to fly, but the total number of limbs is still four.

How many limbs does a dragon have? They have four legs that they stand on, but also two large membranous wings like a bat. This means that they have a total of six limbs. The only other animals that share this trait are insects and other mythical creatures such as the centaur and pegasus.

To be a vertebrate with six limbs, a dragon must have evolved from an ancestor separate to Tetrapodomorpha, an ancient fish-like creature with four limbs that is the common ancestor to all four-legged beasts. Alternatively, the wings may not be true “limbs” and be similar to flying lizards that evolved to have a rib jut out with a membrane attached to act as a glider.

Unlike the scientifically inaccurate dragon, a wyvern obeys nature’s four-leg rule. Furthermore, unlike the traditional Western dragon that we have been describing, dragons of the Far East have no wings and four limbs, also obeying the law.

As ridiculous as it may sound, applying scientific principles to our imagination allows us to learn more about how our world works.

How’s The Water?

Two young fish are swimming along when they happen to meet an older fish swimming the other way, who nods at them and says:

“Morning, boys. How’s the water?”.

The two young fish swim on for a bit, and then eventually one of them looks over at the other and goes:

“What the hell is water?”.

This is a humorous analogy that writer David Foster Wallace told at the beginning of his commencement speech to Kenyon College’s graduating class of 2005. Although it is short, it can be unravelled to reveal many important guiding truths regarding adult life.

Much like the younger fish, many of us are not aware of the “water” that surrounds us. Although we live in it, reality is hard to process because it is made up of so many different layers of complexity. To make it easier to live our lives, our brains protect us from being aware of our reality, much like how people are not aware that they live in a simulation in The Matrix.

Even when we are aware that we are swimming in water, we keep asking ourselves “What the hell is water?”. We search desperately for the wise, older fish who can enlighten us – someone who can teach us what water is.

Many of us will be swayed by countless teachers, mentors, gurus, politicians and religious leaders who tell us to follow them to learn what water is. Many of us will firmly believe that we have grown up to become the older, wiser fish, and fight stubbornly against others who have different views on what water is. Some us may even choose to ignore that the water exists at all.

At every stage of our lives, many of us fall in the trap of believing that we have things “figured out”. Teenagers will rebel against adults, thinking that they will reinvent the world. Young adults will believe that now that they are working members of society, they are entitled to their “educated”, “mature” opinions. The middle-aged believe they have been adults long enough that surely they must have gained enough experience and wisdom on the way. And if we don’t feel confident that we know what water is, we seek the answer from those who claim they know it.

In short, we are always searching for the answer, or claim to have the answer. But that is not the lesson to take away from the parable of the fish in water.
It is not the answer that is important, but the question.

It is hubris to think that we can possibly understand how the world works completely within our lifetime. Instead, we should continue questioning what water is. Otherwise, we are just pretending to be enlightened, all the while becoming dimmer as we shut off our ability to learn and see things from a new perspective.

Consider the countless complexities that make up our reality: physical laws of the universe, the historical context, political climate, shifting cultural norms, societal pressures, chaos theory, our connections to other people… Even if you were to make sense of all this, you will never understand the reality that other people live in, as believing in only your reality stops you from being empathic and compassionate. Remember that water is a great environment for fish to live in, but a person would drown if left underwater.

This is why the parable does not tell the story of the older fish teaching the younger fish what water is. Instead, he is asking them how the water is. He is encouraging them to be aware of the context they live in and to keep question it and learning about it, while he himself stays curious as to how other fish experience the water.

So, how’s the water?

Zodiac: Capricorn

Capricorn is the Zodiac sign for those born between December 22 and January 19. The symbol for Capricorn is a goat with a fish tail instead of hind legs.

The model for Capricorn is the god of shepherds, Pan. Pan had the upper body of a man but a lower body of a goat and was famous for his sexual behaviour (he is often portrayed in art with a massive penis). He is also famous for his music, especially his hauntingly beautiful pan flute performance. But how did a god with the top half of a man and the bottom half of a goat come to represent a constellation where the top half is a goat and the bottom half is a fish? The back-story of Capricorn is related to that of Pisces; that is the story of how the monster Typhon gatecrashed a feast of the gods. While Aphrodite and Eros transformed into a pair of fish to escape Typhon, Pan turned himself into a goat to run away. However, when he reached the Nile River, he hurriedly tried to change into a fish but messed up the spell, with only his lower half turning into a fish. Just before he crossed the river, he saw that Typhon was attacking Zeus, so he let out a horrible screech to scare Typhon, allowing Zeus to escape. Zeus returned the favour by drawing Pan’s image at the time in the form of a constellation.

Zodiac: Pisces

Pisces is the Zodiac sign for those born between February 19 and March 20. The symbol for Pisces is two fish connected by a ribbon.

The model for Pisces is Aphrodite, the goddess of love, and her son Eros. One day, the two were attending a banquet of the gods, having a good time. Suddenly, the banquet was interrupted by a monster named Typhon. Typhon was a terrifying monster 150km wide, with a hundred dragon heads, a hundred mouths through which he breathed fire and had limbs of snakes. He was a composite of various beasts such as oxens and lions, had a black tongue and had eloquent speech rivalling certain gods. When he appeared, the gods were frightened and all transformed into different animals to escape. Aphrodite and Eros jumped into the river, turned into a pair of fish and escaped. It is said that they tied a ribbon to their waists so that they would not lose each other in the stream.

History Of The Earth

The Earth has been around for a good 4.6 billion years. Let us compress the long time from the Earth’s birth to today (2012) into one year to put everything in perspective.

The Earth’s history starts on January 1, 00:00:00. The Earth is a hard sphere, barren as any other planet. Incessant wind and rain erode away the barren mountains and tectonic forces create new ones. Nothing much happens for the next three months. Then, around the start of April, life begins in the form of bacteria. Over the course of the next few months, the bacteria divide and mutate, slowly forming new life forms that are multicellular. However, all life on Earth are still in the oceans.

Life on land only starts in the end of November, when plants begin to settle on land. Plants expertly take the abundant carbon dioxide in the atmosphere and convert it into oxygen. By early December, the oceans are teeming with fish, some of which adapt to living on land by developing lungs. These become the first amphibians. Insects also populate the land and become one of the most diverse types of life.

In December 12, reptiles evolve and the land is ruled by dinosaurs, but only for 9 days until they are wiped off the face of the Earth by a meteorite on December 20. Mammals quickly take the niche left by dinosaurs, populating the entire world. Even at this late time, there are no signs of humans.

December 31, humans have still not arrived on Earth. They only appear around 8pm, where the first hominids venture on to the plains of Africa. At 10pm, the Ice Age begins and the Earth is covered by a thick white sheet of ice. The ice comes and goes three more times. At 11:59pm, human civilisation begins as cities begin to rise. 22 seconds before the end of the year, the Egyptians build their pyramids. More monuments arise within seconds. At 11:59:47pm, Jesus teaches the people to love one another, until he is killed a millisecond later. In the last second of the year (about 150 years), humanity: has two major world wars, take to the skies, create the nuclear bomb that can wipe out all life on Earth and even step foot on the Moon.

We may like to think that we have made a significant impact in the history of the Earth, but we have only existed for an infinitesimally small fraction of the history. We are but a dot on the grand scheme of natural history.

Ghoti

If the gh sound in “tough” is pronounced “F”,
And the o in “people” makes the short “I” sound,
And the ti in “nation” is pronounced “SH”, 
Then the word “ghoti” is pronounced just like “fish”.

This is the shortcoming of the English language, where so many letters can be pronounced in various ways depending on the context of the word. This problem cannot be found in languages such as Korean where every Hangul character can be pronounced a set way, as they each represent a certain sound.

Therefore, there is no other way of saying “moolgogi (물고기, fish in Korean)” other than just that. This is why the Korean Hangul is a far superior and more logical method of writing than the English alphabet.

Whaling

The Faroe Islands are a group of islands between Scotland and Iceland in the North Atlantic Ocean. Although a small nation, they are known to the outside world for their tradition of whaling – specifically pilot whales that are native to the North Atlantic Ocean. The media often show photos of bloody shorelines with a line of whale carcasses, decrying the so-called “inhumane hunting” of the whales. The dramatic scene and cuteness of the whales seems to appeal to the masses and has caused quite a controversy regarding the Faroese tradition, known as grindadráp. However, the media often tells a misinformed story regarding the whaling. One thing to know is that Faroese whaling is fundamentally different to whaling seen in other parts of the world, such as Japanese whaling. 

The Faroese have been killing pilot whales for food for the past millennium and have done so in the most humane and sustainable way possible. Despite popular belief, the pilot whales are not endangered and in fact overpopulated in the North Atlantic Ocean. As they are carnivorous, an overpopulation of the whales causes a shortage in fish. Fishing is the major industry in the Faroe Islands and constitutes their livelihood; so ironically, the pilot whales can endanger the Faroese people by consuming all the fish in the surrounding sea. Thus, the Faroese kill a small portion of the whale population (roughly 0.1%, a completely sustainable rate) to balance the ecosystem while protecting their most important industry and their livelihood.

Faroese whaling is not commercial and only enough whales are killed to provide enough food for the people (equally distributed to the participating families). The killing is not for fun or money, but simply to support the lives of the people. As such, the Faroese have also come up with the most humane way to kill the animals.

When whaling season starts and the pilot whales come near the shore, “drives” are initiated where a semi-circle of boats herd nearby whales towards the shoreline (only whales near the shoreline are killed). When the whales approach the shore, the people use blunt blowhole hooks that catch the whales without causing wounds (unlike harpoons and spears) and draw them closer to shore. Only adult males are drawn in (no females or babies) and only enough that can be killed swiftly are drawn in.

Once drawn in, the men quickly use their knives to cut the spinal cord and artery supplying the brain, killing the whale within 15 seconds of being beached. It is the quickest and most painless way to kill the whales and only those who have been trained to do it properly are allowed to kill. As a major artery is cut and whales are big mammals, a large volume of blood is released, dying the sea a bloody red colour.
The whales are then divvied up equally, with no part of the whale going to waste. As only nearby whales are killed, sometimes no whales are killed for years.

Unfortunately, due to pollution in the ocean, there have been increasing levels of heavy metals such as mercury found in the whale meat. This is endangering the health of the island population and the deeply engrained tradition of grindadráp. The saddest part is that the pollution is from industrialised countries such as USA and European countries, not the Faroe Islands. Yet the Faroese have to put up with bigotry from those who do not understand the culture, process or the reasoning behind the tradition. If anything, it is by far more humane and sustainable than killing animals after a lifetime of captivity then sending them to a slaughterhouse.

It is extremely important to see the truth behind controversial issues such as this, as more often than not the truth is shrouded by bigotry and subjective comments by people who have only seen the issue through some photographs on the internet.

(Notice the single, deep horizontal slash through the dorsal aspect of the spinal cord, just before the brainstem. Such a cut would immediately sever any pain signals and cause almost instant unconsciousness due to ischaemia of the brain.)

Mermaid

You are alone on an uninhabited island. Which mermaid would you choose as your companion? Classic mermaid – top-half woman, bottom-half fish – or inverted mermaid – top-half fish, bottom-half woman?

image

In 1934, abstract artist René Magritte painted Collective Invention – a play on the idea of a mermaid. This mermaid has the lower-body of a woman and the upper-body of a fish. Despite having beautiful, functional legs, the “mermaid” is gazing expressionless and lying on its side. You would think that a fish with legs would be using them, but clearly this creature is too foolish, or is possibly asphyxiating as its gills attempt to respire in vain. As opposed to the normal model of human-fish creatures, this one has gained the transportation and sex-organs that flummox the sea-faring men whom they tempt. What the creature lacks is the personality, and inner/outer beauty of the traditional sea-temptress. One misogynist, who clearly did not think the choice through, called this “a practical man’s mermaid”. 

Perhaps the question of the two mermaids is what part of a woman a man considers more important.

So which would you choose? Go.
