Nude

The concept of the female body being the ideal subject for nude art only became popular around the 16th century when the Renaissance was in full bloom. Art before this time mainly focussed on the male figure that could portray the perfection of gods, such as the young and beautiful Apollo or Jesus Christ on the cross. In ancient Greece, the naked male figure was associated with triumph and victory (possibly related to the Olympic games being played in nude). Thus, statues focussed on nude male figures, with female figures tending to be clothed.

The point in history when this perception of nudity changed was when an Italian artist called Giorgione painted the Sleeping Venus in 1510. This painting portrays a nude Venus (or Aphrodite) lying peacefully on white and red cloths upon the backdrop of Venetia. This new type of nude art where the naked female form was displayed – with the figure posed with grace and shyness – sparked a revolution, changing the concept that the female body evoked an “uncomfortable feeling” in the audience. Many art historians consider this painting one of the starting points of modern art.

Hitler

There are millions of units for various things. Some are simple and standard like the metre and gram, while others are quirky and humorous like the Helen unit and the Banana Equivalent Dose. As long as you can justify it with logic and objective quantification, you can virtually create any unit. Using this logic, some historical knowledge and a cruel sense of humour, one can come up with an extremely disturbing unit called the Hitler unit.

As most people know, Adolf Hitler is one of the most notorious criminals against humanity in the history of mankind. He was responsible for the death of at least 17 million people, including the 6 million Jews and 5 million other ethnicities killed during the Holocaust, and victims of World War II. For simplicity’s sake, let us only consider the victims of the Holocaust as direct victims of Hitler’s ambitions.

Using this statistic, we can now create a new unit called the hitler – equivalent to 11 million human deaths. Ergo, killing a single human amounts to a crime of 91 nanohitlers. The “hitler level” of some of history’s worst notorious dictators are as follows:

  • Kim Il Sung: 1.6 million deaths = 145 millihitler
  • Pol Pot: 1.7 million deaths = 154 millihitler
  • Hideki Tojo: 5 million deaths = 455 millihitler
  • Adolf Hitler: 11 million deaths = 1 hitler
  • Jozef Stalin: 23 million deaths = 2.09 hitler
  • Mao Zedong: 78 million deaths = 7.09 hitler

The hitler unit gives us a clear picture of “how much worse” someone’s crimes are compared to those committed by Adolf Hitler. For example, Jozef Stalin could be considered twice more evil than Hitler.

The true utility of the hitler unit is that like other units, it allows for useful conversions to other units. For example, the EPA currently values a human life at $6.9 million (USD). A simple unit conversion thus tells us that 1 hitler is equivalent to the loss of $75,900,000,000,000 (-$75.9 teradollars). In 2008 when the US Congress failed to pass a stimulus bill following the subprime mortgage crisis, the market lost $1.2 trillion over one day – the equivalence to 15.8 millihitlers. Conversely, if a mugger took $200 from you, they have technically committed a crime of 2.64 picohitlers.

Although the crimes of Adolf Hitler were beyond tragic, this imaginary unit teaches us that almost anything can be quantified in the field of science and mathematics.

Units

In September of 1999, NASA ambitiously launched a Mars weather satellite. But the satellite did not even reach its destination, instead exploding in the atmosphere soon after launch. Why was this? The reason was so stupidly simple. The failure was because of units.

The satellite that was designed by Lockheed Martin was designed using the imperial system (pounds, feet and yards), whereas NASA’s systems used the internationally-used metric system. Because of this simple error, the pride of the USA space program fell to the ground and an astronomical amount of money was burnt to ashes in the air.

Surgeon

In many cultures (especially in Asian countries), the public conception of doctors has changed where surgeons are considered the “real doctors”. This is particularly evident in Asian dramas where main characters tend to be surgeons, saving the patient’s life with dramatic operations and charisma. The idea that surgeons are superior to physicians may go as far as some adults advising medical students to become surgeons for a higher status (again, more evident in Asia). However, as the root of surgery is completely different from that of medicine, technically it is a misnomer to call a surgeon a “doctor”.

This is reflected in the relatively unknown fact that a fully-trained surgeon is referred to as “mister”, not “doctor”. To understand why surgeons call themselves Mr., we must look into the origin of the surgical discipline.

In ancient times, surgery was limited to treating flesh wounds and setting bones (with some exceptions such as trepanation), such as those sustained during battles. Other than the odd few cases of specialised surgeons such as Galen of ancient Greece and Hua Tuo of ancient China, it is hard to find records of doctors employing surgery as a form of treatment. This was mainly due to two reasons: that surgery was considered a “dirty, unrefined” form of treatment, and that surgery was too risky.

For a long time, especially in the Western world, surgery was considered to be of a lower status compared to medicine. It was considered more of a craft tradition – something which physicians believed was beneath them. Because of this, surgeries were mainly performed by barbers in medieval Europe. One can still find evidence of a barber’s alternative historical role on the barber’s pole, which has white, red and blue stripes. The white stripe symbolises bandages, the red symbolises arterial blood and the blue symbolises venous blood. This originates from the practice of bloodletting, where white bandages wrapped around a pole would get dyed red from the blood, giving the appearance of the barber’s pole. The profession of “surgeon” did not formally appear until around the 18th century when a Guild of Surgeons was formed in England. However, physicians refused to accept surgeons as equals for a further century. When they did come to accept that surgery was a legitimate form of medical treatment, the surgeons decided that they did not want to be assimilated as doctors, so they chose to keep their title of “mister” to distinguish themselves from physicians.

The reason why surgery was considered an unrefined art in the past mainly focuses on three issues: bleeding, pain and infections. Before modern surgical developments, uncontrolled bleeding was a real issue in surgery. This not only made surgeries extremely messy, but it was also dangerous for the patient as patients would often die from shock (dangerously low blood pressure). On top of this, anaesthetics was only introduced in the late 19th century, meaning before that, patients had to suffer the pain of their flesh being cut and stitched with no relief. Of course, this meant that surgeries were almost always a brutal scene, with the agonising screams of the patients filling the room, while they sprayed blood everywhere. Lastly, even if the patient somehow survived the surgery without bleeding out or dying from the stress and pain, there still remained a high risk of post-operative infection. Thus, surgeries were most often unsuccessful and were considered a barbaric form of treatment with no promise.

Thanks to medical advancements, surgery has become an important aspect of medicine, where one cannot live without the other. However, the tension still remains between physicians and surgeons, with each profession jokingly mocking the other whenever a chance arises.

Dracula

Dracula is a fantasy/horror novel written by Bram Stoker in 1897. It is written as a series of letters, diary entries and other log entries, telling the battle between the vampire Count Dracula and Professor Van Helsing (with the help of some other people). It is one of the most well-known horror fictions in history and defined the modern image of vampires. Although it seems unlikely, the blood-sucking, immortal, creepy vampire that is Count Dracula is (loosely) based on an actual person.

Vlad III Dracula of Wallachia was a Romanian prince who led his army to fight against the invading Ottoman Empire during the 15th century, which was expanding its reach throughout Europe at the time. He was also referred to as Vlad the Impaler due to his incredibly cruel punishment of prisoners and enemies. He would kill the victims by stabbing their bodies with spears, typically through the anus up to the mouth. He would then have the bodies hanging as a warning to others. The victims would die a slow and painful death as they were drained of blood.

Another interesting fact is that Vlad III was an expert in guerilla warfare and would frequently hide his army in trees and strike the enemy at nighttime. This earned him a legend that he was bat-like – hanging from trees and only attacking at night to drain people of their blood. It is likely that Stoker took this legend and incorporated it into his novel, making Count Dracula able to transform into a large bat.

It is fascinating to see how someone who is portrayed as a noble hero in Romania and Slavic countries is remembered as an archetypal monster in modern times. This serves to remind us that no matter what good deed we may do, the world will only focus on a certain aspect and define you by that characteristic. The world is stubborn, critical and narrow-minded. Ergo, it is a waste of time trying to convince the world that you are a certain kind of person. As long as you know what kind of person you truly are and accept it, you will be able to live a happy life.

Voyeurism

Generally speaking, people do not like it when someone watches them undress or see them in a compromising situation. The act of looking in such a situation when a person explicitly tells you not to is called voyeurism, which is French for looking. Peeking is an extreme violation of trust and privacy and can even be considered a crime. However, there are people like Edgar Degas who made a career out of peeking. Degas is very famous for his portraits of women bathing, combing their hair and drying themselves with towels. Through peeking through windows without permission, Degas was able to capture the women’s natural beauty without any artificial manipulation (if he was not caught).

The prohibition against looking is well-established in heroic mythology.

In the bible, when God decides to destroy Sodom and Gomora (two cities that become so indulgent and decadent that they become the symbol of sin itself), angels warn Lot to leave Sodom with his family. They tell Lot and his family not to look behind them as they flee, for they would become consumed by the sin. However, his wife looks back as they leave and is turned into a pillar of salt.

This story is likely to have been derived from the Greek mythology of the musician Orpheus and his wife Eurydice. When Eurydice is unfortunately killed by falling in a pit of vipers, Orpheus becomes struck with grief and turns to singing and playing his lyre for comfort. The gods are so moved by his sad, mournful songs that they advise him of a way to save Eurydice. On their advice, Orpheus travels to the underworld and persuades Hades and Persephone to release Eurydice back to life with his music. The king and queen of the underworld, who are never moved by such things, are brought to tears by his music and accept Orpheus’ request. However, Hades tells him not to look at Eurydice until they reach the surface. Overjoyed, Orpheus takes Eurydice’s hand and leads her back to the living world. When Orpheus reaches the surface, he looks back in anxiety to make sure Eurydice is still behind him. However, he does not realise that both must be above the surface and when he looks back, Eurydice has not reached the upper world yet. She is dragged back into the underworld, never to return again.

There are many other instances of voyeurism being punished in literature, such as the Peeping Tom who is struck with blindness when he tries to peek at Lady Godiva in the nude, or anyone who makes eye contact with Medusa turning to stone. It is clear that voyeurism has been an integral part of humanity throughout history. No matter how immoral the act may be, the stories show that the hero always looks.

Metal

Next to the discovery of fire and the wheel, the discovery of metals and the mastery of metalworking was arguably one of the most important advances for prehistoric humanity. Metal was far superior to rock, clay, wood or any other natural resource known to man in terms of strength and sharpness. Because of these properties, metal soon became a valuable commodity. It can be seen how much impact metal had on humanity’s history, considering that the stages of human prehistory were named after the type of metal (or lack thereof) that was mastered then: Stone Age, Bronze Age and Iron Age.

The discovery of metal came in two ways.

One was through mining, where prehistoric people discovered that shiny, hard objects were buried in the ground. They later discovered that with enough heat, they could melt the metal out of ores (copper and tin were the first metals to be gathered this way) and mould them into any shape. After smelting technologies developed, our ancestors found that mixing copper and tin produced bronze – a much stiffer and more durable metal than either of its components. A mixture of metals is called an alloy. This was the start of the Bronze Age. Bronze was extremely useful and people quickly came up with innovative ways of using it, such as farming equipment and weapons.

Some other metals used during this age were: gold, silver, lead and mercury. It is likely that gold was one of the earliest metals used as it comes in pure nuggets and is easily workable thanks to its chemistry. However, given that gold is rather soft and was treated more as jewellery than a practical metal, it was not used as much to advance technology.

The second way mankind came upon metals was in the form of “gifts from the gods”. A prime example is iron. Although the Iron Age began around 1200BC at the earliest, there are iron objects (mainly jewelleries) that have been dated back to 5000BC. How could this be? This was before mankind had the technology to smelt iron ores (which is more difficult and needs much higher temperatures than copper or tin ores), so the iron could not have been gathered through mining. The answer to this conundrum lies in meteorites. About 6% of meteorites contain iron and nickel, which prehistoric civilisations may have stumbled onto and taken the shiny pieces back to their tribe. The people would have considered the gathered iron a “gift from the gods”, as it had crashed down from the “heavens”. Because of this reason, iron was considered more valuable than gold or silver and was frequently used for jewellery. This is reflected in Arthur C. Clarke’s science fiction short story, The Songs of Distant Earth, where sentient sea scorpions hoard metal objects stolen from the humans and wear it proudly as a badge of honour.

The history of iron and how it was believed to be a gift from the heavens relates to a common superstition of how finding a penny (or any coin) represents good luck. As “metal” (mainly iron) was considered a holy gift bestowed unto mankind, finding a piece of metal was believed to be a blessing and some form of protection against evil. This is also represented in various traditions such as hanging horseshoes over doorways and wearing charm bracelets with metal on it.

Although it sounds like a silly superstition, it clearly shows how metals have been an integral part of the development of civilisation.

Caesarean Section

(To read about how babies are made and born, read the From Cell to Birth miniseries! https://jineralknowledge.com/tag/arkrepro/?order=asc)

Most animals give birth through a female’s vagina. Of course humans are the same when it comes to natural birth, but nowadays, it is not uncommon to find women wanting a caesarean instead of the traditional method. A caesarean (also called C-section) is a surgical procedure where the fetus is taken out by cutting through the lower abdomen into the uterus. The history of caesareans is quite dark. Back in the old days when medicine was not advanced, caesareans were mostly used to rescue fetuses from mothers who had died during childbirth. The first record of a successful caesarean where the mother survived dates back to the 1500s. Many people believe the word “caesarean” came from the Roman emperor Julius Caesar, who was allegedly born via a caesarean. However, it was rare for caesareans to be performed in Roman times and even if they were, the mothers almost certainly died in the process. Given that his mother was alive and healthy well into his adulthood, it is highly unlikely that Caesar was born by caesarean (there are no concrete records of it either).

There is much debate to whether a caesarean is better or worse than natural birth (except in emergency situations where a caesarean is required). According to research (in cases without known risks to the fetus), the mortality rate is definitely higher in babies born by caesarean compared to those born naturally. This is most likely due to a caesarean bypassing some of the physiological changes that occur during vaginal birth.

Another debate is about the use of general versus regional anaesthesia (spinal block) when doing a caesarean. A fascinating fact about childbirth is that when a baby is born, it cries to expand its lungs but then quietens down for about an hour (unless it is in pain or there is some stimuli). This is possibly a mechanism to allow bonding between the mother and baby. New mothers often remember the moments following the birth of the child as extremely emotional and blissful. Contrastingly, mothers who are under general anaesthesia and not awake when their child is born bond less with the baby initially (some mothers do not even recognise the baby as their own). Thus, unless it is an emergency caesarean, a spinal block (which allows the mother to be awake and painless) is preferable over general anaesthesia.

Lastly, it is common tradition to cut the umbilical cord straight after the child is born. But is this okay? When the fetus is in the uterus, it shares its cardiovascular system with the placenta. The umbilical cord connects the two and carries blood to and fro. At any given point, the placenta contains 30~50% of the fetal blood. If the umbilical cord is suddenly cut, the fetus essentially loses this blood, being born in a state of low blood volume. If you look at the umbilical cord, you can see that it is about 1m in length, which is enough for the baby to be put next to the mother’s breasts for breastfeeding and bonding. Perhaps we are cutting the cord too soon, not letting the blood flow back from the placenta to the fetus.

If you think about it, humanity has been giving birth without too many problems to survive generation after generation for 200,000 years (otherwise we would not exist). Although the mortality rate was high, Mother Nature has optimised childbirth over time through evolution. Ergo, it is possible that modern medicine is intervening too much in a natural process. We must always consider whether medical advances are helpful or harmful to us.

Talent

The following is a story from a school in Detroit, USA, many years ago. One day during class, the class lost a mouse that was needed for an experiment. The students looked desperately for the mouse, but no one could find it. The teacher then said: “Everyone be quiet, Stevie Morris will be able to find the mouse”.

The students replied: “That’s impossible, Morris will never find the mouse”. The reason being, Morris was blind.

The teacher said: “You’re right. But Morris, while not being able to see, has excellent hearing. He will be able to hear and find the mouse that you cannot see”.

Morris was extremely touched by this comment. He realised that his blindness was not just a disability, but also gave him a superior sense of hearing compared to others. Morris used his hearing to nurture his musical talent and became a successful singer-songwriter. This boy is Stevie Wonder.

Talent is not something grand. At first, it merely appears tiny, useless and infantile. Stevie Wonder only started off as a boy with good hearing; he was not born a genius singer-songwriter. To develop a talent into a real talent, two extra factors are needed. The first is a master, such as Stevie Wonder’s teacher, who can identify and nurture a child’s natural talent. The second is another talent that when combined with the master’s guidance, develops the talent into something great. This something is effort. Effort is a talent that everyone can have. Those who complain that they are talentless are simply people who have not yet put in the effort.

To End All Wars

In his play Lysistrata, Greek playwright Aristophanes gives a comic account of one woman’s extraordinary mission to end the Peloponnesian War – a 30 year old war between Athens and Sparta. How did one woman bring an end to such a deadly war?

In the play, Lysistrata (the female protagonist) becomes sick and tired of men treating women like simplistic hedonists incapable of functioning on their own. She believes that the war is a result of irrational men making stupid decisions and the long war is a waste as young, nubile women are aging away. She holds a convening of the women of various city states and proposes that the women must rise up to stop the war. Lysistrata’s plan is simple: withhold sex from the men until they cave (i.e. a sex strike). The women are reluctant at first, but agree to join her. They then take over the acropolis of the city, setting up a safe haven for women, barring any man from entering.

The men initially scoff at this revolution and try repeatedly to lay siege on the acropolis. However, they fail and the women continue to not provide any sexual pleasures to any male. The men constantly make snide comments about how women are hysterical and only seek pleasure, but sooner or later, they become desperate for sex. One by one, desperate men (sporting “burdens”, i.e. erections) come to the acropolis, pleading for relief (funnily, some women desert the acropolis in desperation for sex as well). The women take the men in, but only to tease them and leave them disappointed.

Eventually, the men (of both Athens and Sparta) cave and surrender, agreeing to end the war. There is a hilarious scene during the peace talks where Lysistrata brings out a stunning young girl named Reconciliation in front of the men, quashing any complaints or objections. Even the men who protest against the women’s demands are overcome by their lust and want(/need) for sex. Once peace is declared, the men and women all come together in the acropolis for singing and dancing, celebrating the women’s success in ending the war.

Although the play is only a comic exploration of the battle of the sexes, it clearly shows the power women have over men, and how they can use that power to easily control men.
