The ritual of blowing out candles on one’s birthday is interesting as it shows the characteristics of human beings very well. This ritual shows that the person can make fire while reminding themselves they can extinguish it with one breath. It is a ritual that helps a baby develop into a responsible, social being that is capable of controlling fire. On the other hand, an old person being so breathless that they cannot even blow out a candle signifies that it is time for them to be socially excluded by the active population.

Lemming
When you think of lemmings, you are bound to think of two things: a small, round rodent and mass suicide. The reason being, we have been taught as children that lemmings often commit mass suicide. This theory originates from the late 19th century when scientists could not figure out why lemming populations seemed to spike rapidly and then fall just as fast. In 1908, a man named Arthur Mee proposed that they kill themselves, writing so in the Children’s Encyclopaedia. He posited that as an overpopulation of lemmings could devastate the European ecosystem, the lemmings were naturally controlling their own population count. His theory was backed by a documentary made in 1958 called White Wilderness that showed a footage of a herd of lemmings leaping off a cliff to their death.
However, this “fact” has a severe flaw. Lemmings do not commit mass suicide. If you think about it for even a second, the thought of an animal that commits mass suicide (other than human beings) is preposterous as the species would die out. The reason why the lemming population spikes is the same as for mice and rabbits: they pride themselves in extreme reproductive abilities. A female lemming can have up to 80 babies in one year. If the population grows at such an alarming rate, then as explained above, the environment would not be able to support it. This causes the lemming population to plateau, not rising or falling, as there is not enough food to feed all the lemmings. However, due to the shortage of food, the lemmings become desperate and hungry. To find more food, the lemmings begin a migration, but the combination of hunger and being in heat causes them to act irrationally and wild. The result is a massive herd of hungry, stupid lemmings frantically running around all over the place. This leads to some lemmings accidentally slipping off cliffs and drowning in the river while swimming. This is not suicide.
Then what was the strange phenomenon of mass suicide depicted in White Wilderness? The answer is simple: it was staged. The producers tried to replicate Mee’s theory by importing a dozen lemmings and filming them running around the place. Then why did these lemmings commit suicide? Because the producers launched them off a cliff from a turntable.
Six Degrees Of Separation
It is said that through a chain of five people, we can be acquainted to anyone in the world. In other words, an Eskimo man can be no less than six steps away from a Parisian lady. This is the concept of the six degrees of separation.
The concept can be explained mathematically. We all know hundreds of different people each. If we assume that we each have 100 friends, then in the first stage we only know the 100 friends. However, at the second stage we know the 100 friends of each of our friends, meaning we know 10000 people. At the third stage we know 1 million people, fourth stage 100 million and fifth stage 10 billion people. As the world population is 7 billion, by the fifth stage we should theoretically know every person on the world. This means that crossing four metaphorical bridges lets us shake the hands of anyone we want. The concept of the degrees of separation came from the idea of the small world phenomenon.
The first person to properly study the small world phenomenon was Harvard social psychologist Stanley Milgram. In 1967, Milgram asked 296 people in the Midwest (USA) to help him send a package to someone in Boston. To complete the experiment, the participants had to send the package to one of their friends they thought would know this stranger in Boston. Milgram found that in half of the cases, the package was delivered to the target in Boston through five people (5.5 exactly), thus giving birth to the concept that we are at six degrees of separation from another human being.
Of course since 1967 our societies have undergone many changes. One of the most noticeable changes has been the development of technology – specifically the development of the internet and social networking. Nowadays, the younger generations use the internet to communicate with friends and make connections. Knowing this, what degrees of separation exists in modern societies? According to a recently finished study (2011) using data from the social networking site, Facebook, the average number of “bridges” for the world is 4.7. In countries such as the US where there is a bigger proportion of Facebook users, this number fell to 4.4. Ergo, in the past 40 years we have developed more connections to other people, making our world even smaller.
The theory of six degrees of separation reminds us how small a world we live in and how interconnected we are to each other.
Umami
Normally when people think of “tastes”, they think of sweet, salty, sour and bitter (“spicy”, or piquance is not a taste). However, in 1985 the family of four basic tastes were introduced to a new member: umami. Umami, commonly known as “savouriness” is a taste that has had its own word in Asian countries (e.g. 감칠맛, or gamchilmaht in Korean) for thousands of years but has not had a proper English word until very recently (much like piquance). Umami is a portmanteau of two Japanese words: うまい(umai) and 味(mi), which means “delicious” and “taste” respectively.
Sweetness comes from glucose, saltiness from sodium and sourness from acids. Then where does umami come from? Umami is the taste born from glutamates, which is found in high concentrations in meat products, thus leading to the association between umami and the taste of meat. For example, bacon is known to have six different types of umami flavours, creating a unique and addictive taste. Another product high in glutamate is monosodium glutamate, or MSG. MSG is essentially glutamate plus a sodium ion and thus brings out the full taste of umami when added to food. As umami has a powerful effect of boosting appetite and having a slightly addictive property means that chefs like putting MSG in foods to boost sales. Contrary to popular belief that MSG is detrimental to your health, recent researches have shown that unless you have an allergy to it, MSG is safe to consume even in high concentrations.

Monty Hall Problem
Imagine that you are on a game show and you are given the choice of three doors, where you will win what is behind the chosen door. Behind one door is a car; behind the others are goats, which you do not want. The car and the goats were placed randomly behind the doors before the show.
The rules of the game show are as follows:
- After you have chosen a door, the door remains closed for the time being.
- The game show host, Monty Hall, who knows what is behind the doors, opens one of the two remaining doors and the door he opens must have a goat behind it.
- If both remaining doors have goats behind them, he chooses one at random.
- After Monty Hall opens a door with a goat, he will ask you to decide whether you want to stay with your first choice or to switch to the last remaining door.
Imagine that you chose Door 1 and the host opens Door 3, which has a goat. He then asks you: “Do you want to switch to Door 2?”
Is it to your advantage to change your choice?
Most people believe that as an incorrect option (goat) is ruled out, their odds of winning the car go up from 1/3 to ½ even by staying on the same Door 1 and there is no benefit to switching. However, it is better to switch doors as this will double your odds of winning the car. To illustrate this point, the following three scenarios (with the car being behind Door 1, 2 or 3) can be imagined, using the above rules of the game:
In Scenario 1, you have already chosen the car (Door 1) so Monty Hall will randomly open Door 2 or 3. Switching will obviously lead you to losing the car. The chance of you losing after switching, therefore, is 1/6 + 1/6 = 1/3 (as either Door 2 or 3 could be opened)
In Scenario 2 and 3, because you chose the wrong door (goat) and Monty Hall will open the door with the goat behind it, switching will lead you to choosing the car (no other choices). As the odd of either scenario happening is 1/3 each, your odds of winning after a switch is 2/3 – double the odds of winning after not switching (1/3, the odd of your first guess being right).
Of course, this is only under the assumption that the rules of the game were followed and that Monty Hall will always open a door with a goat behind it. This problem and the answer suggested was extremely controversial as tens of thousands of readers refused to believe that switching could be a better choice. However, as the above illustration shows, the Monty Hall problem is a veridical paradox – a problem with a solution that appears ludicrous but is actually proven true by induction.
Cordyceps sinensis
Cordyceps sinensis is a fungus known as dongchoong-hacho(동충하초, 冬蟲夏草) in Korea, with the same characters used in China and Japan. It literally translates to “worm in the winter, herb in the summer”. It is a peculiar fungus with an interesting life cycle. In the summer when the weather is warm, the fungus infects its host (usually ghost moth larvae) through spores. The infected caterpillar is slowly filled with mycelium (thready part of fungi), until it becomes mummified with only the shell remaining. The fungus keeps replicating until it bursts out of the caterpillar’s head with a club-like fruit body (which holds the fungus’ spores). This makes it look as if the caterpillar, which was an insect in the winter, turned into a fungus in the summer (technically it is at this stage, but the caterpillar is long dead). In English, it is also called caterpillar fungus or vegetable worm (which is a misnomer as fungi are not vegetables).
Cordyceps sinensis is an important ingredient in traditional Eastern medicine as it is believed to be a perfect balance between yin and yang due to it possessing both animal and plant (actually a fungus) properties. It is used to treat many diseases from fatigue to cancer.
Although Western medicine usually looks down on and ignores Eastern medicine, research shows that Cordyceps sinensis actually has medicinal properties. Cordycepin, a chemical extracted from the fungus, has been shown to inhibit the growth of viruses, fungi and tumours through its inhibitory actions on a certain protein. There is also research that suggests it can protect the body against radiation poisoning.
Sandwich
Although the concept of eating two pieces of bread with meat and vegetables in between has existed since the invention of bread, the word “sandwich” is a much more recent invention.
During the 18th century, there was an aristocrat called John Montagu, 4th Earl of Sandwich who loved to gamble. He loved gambling so much that he barely had time to eat a proper meal, so he frequently ordered simple foods from his servants.
His favourite was two pieces of bread with sliced meat in between. Every time he gambled with his friends, he would order this snack from his servants and his friends would say “the same as Sandwich!” when ordering. This playful comment stuck over time and people began officially naming the type of food a “sandwich”.
A sandwich is the perfect snack invented just for those who have no time or are too lazy.
Fermat’s Last Theorem
In the 17th century, a lawyer called Pierre de Fermat conjectured many theorems while reading a mathematics textbook called Arithmetica, written by an ancient Greek mathematician called Diophantus. He wrote his theorems on the margins of the books. After his death, a version of the Arithmetica with Fermat’s theorems was published and many mathematicians checked over Fermat’s proofs. However, there was one theorem that could not be solved. Fermat wrote on the theorem: “I found an amazing proof but it is too large to fit in this margin”.
Fermat’s last theorem is as follows:
No three positive integers x, y, and z can satisfy the equation
xⁿ + yⁿ = zⁿ for any integer value of n greater than two.
For example, x² + y² = z² can be solved using Pythaogorean triplets (e.g. 3, 4, 5) but there are no values for x, y and z that solves x³ + y³ = z³. This theorem remained unsolved for 357 years until Andrew Wiles finally found the proof in 1995.
There are many stories surrounding Fermat’s last theorem, but by far the most interesting is related to suicide. In 1908, a German mathematician called Paul Wolfskehl decided to kill himself after being cold-heartedly rejected by the woman he loved so much. He decided to shoot himself at midnight and in the remaining time started reading some mathematics texts until he found a flaw in Kummer’s theory, which disproved Cauchy and Lamé’s solution (the leading solution at the time. After Kummer’s essay, most mathematicians of the time gave up on Fermat’s last theorem). After researching Kummer’s essay, Wolfskehl found that it was far past midnight and he felt great pride in reinforcing Kummer’s solution. His depression was gone and through mathematics he found new meaning in his life. Wolfskehl, who believed that the theorem saved his life, made a resolution to donate his wealth to whoever solved Fermat’s last theorem, putting up 100,000 marks as a prize. This prize was claimed by Wiles in 1996 (then worth $50,000).
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.)
