Metal

Posted on by Jinavie

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.

Flow

Posted on by Jinavie

Have you ever had a moment of pure passion, where you are so immersed in what you are doing that everything around you does not matter and you are in a state of total bliss? In that moment, you feel fully alive, present and completely engaged with what you are doing. When the happiness and creativity expert Mihaly Csíkszentmihályi was studying how painters work, he noticed an odd thing. When their painting was going well, they did not care about getting tired, hungry or uncomfortable. They just carried on. But when the painting was finished, they rapidly lost interest in it.

Csíkszentmihályi described this state of mind as a flow state: the experience of being fully engaged with what you are currently doing. When in a flow state, an hour can pass in the blink of an eye, action and awareness merges and the experience is intrinsically rewarding. You feel that what you are doing is important, in full control and not self-conscious. Flow state does not just involve ultimate concentration. It is a complex state of mind where you are solely driven by focused motivation, operating at your peak level of mental and emotional engagement. Essentially, your mind uses 100% of its capacity for the task at hand, rather than wondering what is for dinner or peeking at the beautiful girl across the road. Because of this, a person in flow state not only works with great efficiency and creativity, but they also feel positive, energised and happy. In fact, the intense spontaneous joy brought on by flow state can almost be considered the mental equivalent of an orgasm.

So how can you achieve flow state? Flow state is not something that one chooses to go into. It is only attained when certain criteria are met.

  • Flow state can happen with any activity, but it is more likely to occur if you are internally motivated (i.e. you are doing the activity mainly for its own sake).
  • You should have clear short-term goals for what you are trying to achieve. This adds direction and structure to the task.
  • An important aspect of flow is that the activity must be challenging enough to stretch your skills almost to the limits, but not more. If it is not challenging enough, you will get bored. If it demands more skill than what you are capable of, you will become anxious. That being said, the balance only has to be between “perceived” challenge and skill. In other words, all you need is confidence that you can take on the challenge.
  • The activity should provide immediate feedback on how you are doing (e.g. seeing how a painting is turning out, hearing yourself sing). This allows you to adjust your performance in order to maintain flow state.

Flow is an incredibly useful thing. Through flow, you can forget about your worries and your strife, reach a state of pure happiness and inner peace and produce something truly great. The key to happiness is knowing what allows you to reach flow state and routinely entering flow state. For example, I know that the three things that give me flow are: music, humour and obsessions. Ergo, I play my guitar and sing, watch television shows that make me laugh and write an entry for the Encyclopaedia of Absolute and Relative Knowledge every day. All of these activities allow me to be truly happy, no matter what the situation may be.

Reaction

Posted on by Jinavie

If you were walking along the street and found a bird lying on the ground, how would you react? You would probably poke the bird to see if it is alive. We have a peculiar habit since we are children of poking living things that we see for the first time. Through poking, we discover whether it is alive or dead, soft or hard, slimy or furry, docile or aggressive.

Prompting a reaction and observing the reaction is a surprisingly useful way of learning. In chemistry, we react an unknown substance with other chemicals to discover its identity. In medicine, we stimulate parts of the brain with electricity to discover what each part does. In physics, we build giant accelerator to crash particles together to find out their constituents and properties. If you fell into a cave so dark you cannot see even one foot ahead of you, the best way to find out if there is a wall or a hole or water ahead of you is throwing a rock in that direction.

This principle can be applied to psychology. To learn how people around you behave, provoke them. Human beings are extremely sensitive to stimuli and even when they consciously try to hide it, they will subconsciously react. If you keep (subtly) poking the person, you will soon be able to predict how they will react to something, what actions they will take, and you may even discover what is on their mind.

We cannot see the wind, but we can infer that it exists because the leaves blow. The best way to prove something that you cannot see inducing and looking for reactions.

Communication

Posted on by Jinavie

What I am thinking,

What I want to say,

What I think I am saying,

What I say,

What you want to hear,

What you think you are hearing,

What you hear,

What you want to understand,

What you think you understand,

What you understand,

Because there are ten possibilities between what I think and what you understand, there is great difficulty in our communication.

But even so, we must try.

Caesarean Section

Posted on by Jinavie

(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.

Hiring

Posted on by Jinavie

The Central Intelligence Agency (CIA) of the United States is famous for using a variety of hiring strategies to find agents who would be well-suited for spying. There were many strange and unique strategies among these. The following is a good example of a very strange, but simple and effective strategy.

First, put out a job advertisement on the newspaper. The ad tells people who are interested should come to a certain office at 7am on a certain day. The ad says nothing about what documents you need to bring, whether it is an interview or a test, or even what the job is. About a hundred applicants arrive on the day at 7am, but the office is empty with no employers or instructions. For two hours, no one comes and many impatient applicants complain that they fell for a prank and leave. An hour later, more people express frustration and leave, saying how rude the company is. By 1pm, about half the group has left, slamming the door behind them. By 5pm, only about a quarter remain. Finally, it becomes midnight. There are only one or two people left by this stage. These people are automatically hired.

Overpopulation

Posted on by Jinavie

In 1972, John B. Calhoun designed a very specific mice cage called Universe 25, also known as the Mortality-Inhibiting Environment for Mice. Universe 25 was designed as a practical utopia for mice. It was constantly replenished with food and water, each wall had an intricate grid of nesting boxes connected by mesh tunnels and stairwells (like an apartment) and the cage was cleaned periodically. There were no predators, the temperature was set at a comfortable level and all mice resident were disease-free. In all ways, Universe 25 was an idyllic home for the mice.

Calhoun’s aim of this experiment was the same as the countless experiments before Universe 25: to see the effects of abundance on a population, and the consequences of that. Biologically speaking, a population only grows to the point that the environment can sustain it and then plateaus. So if the environment is completely abundant, the population will grow and grow without limitations (other than space). Thus, Calhoun’s main focus was overpopulation in societies. What did he find?

At the start of the experiment, four breeding pairs of mice were introduced to Universe 25. They began reproducing after 104 days of familiarisation and the population increased exponentially. The mice flourished in the prosperous environment. Around day 315, population growth slowed. By this stage, the mice population had grown to over 600, which made Universe 25 very crowded. Although there were still plenty of resources, the problem of overpopulation still remained. As the population grew and space became limited, male mice found it too difficult to defend their territory and eventually gave up doing so. The mice began losing their ability to form social bonds and these mice (“failures”) began congregating at the centre of the cage. This group of mice gave up on all normal social behaviour, leading to constant violence. The violence soon spread throughout the cage, with the mice society descending into chaos. The females, stressed and confused by the violence, attacked and cannibalised their own young, after which they retreated to the highest nest boxes where they isolated themselves. Certain males (termed “the beautiful ones” by Calhoun) did not show violence or any interest in females, choosing only to eat, sleep and groom themselves, wrapped in narcissistic introspection. Because of these two isolated groups, procreation slumped and population growth slowed. Elsewhere, in the “inner city” group at the middle of the cage, cannibalism, pansexualism and violence became common. The entire society had collapsed.

On day 560, the population ceased to grow at a peak population of 2200. After this, the number of pregnancies dwindled to nothing and no young survived past infancy. Adult mice were also affected, with mortality rates skyrocketing at all ages and increased rates of diseases. It was clear that the population was headed towards extinction. Even after the population dwindled down to a much more sustainable number, the mice were incapable of (or chose not to) reproducing to regenerate the population. Not only did mice society die, but the mice themselves met a grim fate as well.

This result was repeated in all of Calhoun’s experiments, conclusively showing that overpopulation leads to the demise of a society. Calhoun described this as “crowding into the behavioural sink”. He explained that the mice served as a warning to what human societies are headed towards if we do not solve the problem of overpopulation. We can already see the effect overpopulation has on societies. It is a known fact that people living in the inner areas of a city are more prone to poverty, crime, violence and a lower quality of life. However, Calhoun was not a nihilist. Instead of saying “humanity is doomed”, he explored different ways of resolving the problem. The most effective idea he came up with was space colonisation.

Verneshot

Posted on by Jinavie

If there is one thing we learn about dinosaurs, it is that they were wiped off the face of the Earth by an asteroid impact. Another feasible theory is that a supervolcano eruption completely destroyed the ecosystem, wiping out all life on Earth by either directly destroying them via a massive shockwave (if they were within range), or by slowly starving them as the resultant plumes of smoke would have blotted out the sun for years. But interestingly, scientists looking back over some extinction-level events of the past, discovered signs of both an asteroid strike and a volcanic eruption. This sounds to be extremely implausible, as the odds of both happening in the same era are near impossible (unless there is some extremely vengeful deity that hated the dinosaurs).

One theory that tries to explain all of this is the verneshot theory. To better understand the concept of a verneshot, imagine a cartoon character such as Yosemite Sam (the beloved red-bearded, gunslinging cowboy character on Looney Toons) shooting his gun wildly into the sky. Cartoon logic dictates that his bullets will eventually fall back on some unwary bystander. Now imagine if the Earth did the same thing, but instead of a bullet it shoots a giant piece of rock capable of causing mass extinction into the sky.

A verneshot occurs in a similar way a supervolcano erupts, where there is an incredible build-up of super hot molten rock. A supervolcano would be when this molten rock erupts as lava. In the case of a verneshot, massive amounts of carbon dioxide build up instead, leading to a pressure build-up under the crust. When the pressure becomes too much, the crust explodes, with the piece (of indeterminate size) being rocketed into space. However, the giant rock does not end up in space. Instead, it is only launched to a sub-orbital altitude, meaning it will come crashing back down to Earth due to gravity. Thus, a verneshot is when a volcanic eruption acts as a giant cannon to launch a piece of the Earth into the sky, which falls back to Earth as an asteroid-like object.

True Love

Posted on by Jinavie

Let us assume that everyone has a person they are destined to end up with. Can we calculate the probability of such a fateful meeting between a man and a woman?

Suppose that the woman is X and the man is Y. Firstly, X and Y need to be born as human beings. They cannot be born as a worm or an onion or something. Here, we will say that the total number of species is M and the population number of each species as P (technically this part is forcing it slightly, so we can skip it).

Although the two have to beat ridiculous odds just to start, just being born as human beings is not enough. One must be born with XX chromosomes to be a woman, and the other must be born with XY chromosomes to be a man.

Let us assume that the two were lucky enough to be born as a man and a woman. Next, they must live in the same space. If one lives in some Korean city and the other lives in some American rural village, it is unlikely the two will ever meet.

Even if they did live in the same place, X and Y must have subjective qualities that the other person finds attractive. If they are not interested in each other, nothing will happen even if they did meet. By this stage, we have clearly gone past the scopes of mathematics.

Then let us assume that a man and a woman, who fit each other perfectly and born as people, are living in the same space. We are still missing one variable: time. Even if we took only the 5000 years that civilisations have existed, the odds of the two being born in the same era as similar ages is less than 0.001%.

Species, sex, space, time… Statistically speaking, the chances of a man and a woman beating all of these odds to establish a perfect couple seem nearly impossible. But we can clearly see that “true love” exists all around us. Numbers are just numbers. If you find a person that makes your heart skip a beat when your eyes meet, that makes you feel that the more you get to know them, the more you think you cannot live without them; in essence a person that makes you think “this person is The One”, do not let the person slip away. The scenario of you and that person existing on the same space-time and loving each other is something that verges on the impossible.

There is no treasure as rare as true love. If you have found true love, or believe that you have found it, fight to seize it and do everything in your power to protect it. That is the greatest accomplishment you can make in life.

Talent

Posted on by Jinavie

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.
