Identity

Posted on by Jinavie

Do you want to gain trust and build intimacy with someone? That is easy – all you have to do is recognise and accept their identity. Every person tries to define who they are by building an identity or their “self”. This identity includes their personality, experiences, philosophies and interests. If you wish to have a deep and meaningful conversation, start off with a light conversation to explore the person’s identity. What kinds of films do they like? What leisure activities do they enjoy in their free time? What occupation are they in? If you slowly learn such superficial information, an outline of their identity begins to take place. Also, observe the person’s attitude as they speak and how they respond to certain topics. You will be able to know or at least guess what their interests are.

As the person slowly becomes fond of you through conversation, simply lead the conversation towards their interests that you found out. The person will talk excitedly about their interests. Now, respond accordingly with a smile and a look of interest (better if you are actually interested). A positive conversation has been established. Steer the conversation so that the other person talks as much as possible about their “self”. The person will think that you share their interests, and nothing is as attractive as common interests.

Shall we go one step deeper? Interests give an outline and begin to add colour to the identity, but to recognise their identity as a whole you must gather more specific data. Once a sense of trust and intimacy begins to develop, the conversation can develop into a more personal one. Talk about the person’s past, their philosophies, their dreams, hopes and aspirations. The more intimate information they share with you, the deeper the intimacy becomes and the more you learn about their identity. The important point here is that you not only learn about their identity, but acknowledge it every step of the way. The greatest gesture you can make to another person is accepting them for who they are. If you talk with someone that understands you and accepts you, you will talk as if time does not matter and share your deepest secrets.

On the other hand, if you wish to attack an enemy psychologically, what could you do? As you might have guessed, you should attack their identity. Pull out all of their weaknesses and faults and attack them, while logically disproving their fundamental beliefs and philosophies. Systematically pull apart their psyche and destroy the pride they have for their identity and even the strongest enemy will fall to their knees.

Hypothermia

Posted on by Jinavie

A person’s body temperature is always maintained between 36.5~37.5°C. This is because enzymes, which are crucial in all physiological reactions in the body, work most efficiently at this temperature. As physiology is essentially a series of chemical reactions, it is heavily dependent on temperature. If the temperature falls, chemical reactions occur slower and vice versa. When body temperature falls below 35°C, metabolism becomes too slow and it poses a risk to the person’s health. This is known as hypothermia.

How does hypothermia affect the body? Hypothermia is categorised into three classes depending on the severity.

  • Mild hypothermia (32~35°C) leads to the slowing of bodily functions, tremors and difficulty in walking. The patient’s speech is impeded and other neurological symptoms such as decreased judgement skills and confusion start to appear. Also, blood pressure, pulse and breathing rate rise.
  • Moderate hypothermia (28~32°C) causes paralysis of muscles and extreme fatigue (they may complain of being sleepy). As blood (carrying heat) is rerouted to major organs, the skin (especially lips and extremities) become white or purple and very cold. Neurological symptoms worsen with amnesia, memory loss, severe confusion and delusion beginning to show. As sustained hypothermia leads to the tremors stopping, one should not take the lack of tremors as a good sign. Heart rate becomes irregular and arrhythmia may occur.
  • Severe hypothermia (20~28°C) leads to chemical reactions becoming so slowed that physiological functions that support life decline dramatically. Heart rate, blood pressure and breathing all lower to dangerous levels and the heart and lungs may stop functioning. As the patient’s major organs begin to shut down, they enter a state of unconsciousness and eventually, clinical death.

As you can see, hypothermia is a highly dangerous situation that can kill. There are some other fascinating facts about hypothermia.

20~50% of hypothermia death cases are associated with paradoxical undressing. This is a strange phenomenon where the person begins to take off their clothes due to confusion and a lack of judgement from the hypothermia. One theory suggests it is related to the cold damaging the hypothalamus (which controls body temperature), causing the brain to think that the body temperature is rising. Whatever the reason, it is extremely dangerous as it worsens the hypothermia.

As explained above, severe hypothermia leads to death. But interestingly, hypothermia also protects organs. This is why organs for transplanting are transported in ice. Similarly, there are examples of people who “died” from hypothermia recovering with no brain damage. Because of this, medical professionals traditionally say: “they’re not dead until they’re warm and dead”. In fact, if there is something wrong with the patient’s circulation and there is risk of damage to their organs (such as in surgery), sometimes the patient’s body temperature is forced down with ice water injections and cooling blankets, known as protective hypothermia.

Resonance

Posted on by Jinavie

The power of vibration is incredible. Vibration allows a microwave to heat food and causes cities to be destroyed by earthquakes. The most interesting feature of vibrations is resonance, where a vibration of certain frequency greatly amplifies the vibration of another object. Every object has a natural oscillating frequency and when another wave of the same frequency hits the object, the oscillation suddenly amplifies and resonance occurs.

The best example for resonance is a swing. If you push a person on a swing at the same frequency as the swing’s natural frequency, you can achieve a much greater height than from pushing at any other frequency. Resonance can also be used to shatter a glass with only sound, by singing a sustained note at the same frequency as the glass’ natural frequency.

Resonance is how two things combine to create an even greater force.

How To Sleep

Posted on by Jinavie

Do you suffer from insomnia? Tossing and turning in bed for hours every night while enduring the onslaught of fatigue and a sense of uneasiness is hard on both the body and the mind. There are many “remedies” such as drinking warm milk or exercising lightly but those rarely help. If you find yourself staring into the dark ceiling and unable to fall asleep again tonight, try the following trick.

First, calm your mind and breathe deeply. As you breathe in, count “one”. Remove all other thoughts and focus on the 1. Now, breathe out. As you breathe out, count “two”. Inhale, 1. Exhale, 2. Inhale, 1. Exhale, 2. If you think about nothing other than your breathing and counting, you will find yourself drifting off into dreamland in no time.

Microwave

Posted on by Jinavie

The following are some strange things that happen when certain objects are placed in a microwave (and then turned on).

  • Never put metallic objects in a microwave. Metals act as an antenna, collecting the microwave and creating an electric current. This causes the metal to heat up, burning the food or melting plastic containers. Also, if the metal is pointy, it may cause an electric arc (sparks) which can be very dangerous. 
  • Ice alone does not melt in a microwave. This is because microwaves cause vibrations of particles to generate heat, but in ice the water molecules are tightly bonded and so vibration does not occur. 
  • Microwaves can cause something called superheating of liquids. This means that the liquid is heated to beyond its boiling temperature without boiling. A superheated liquid can spontaneously begin to boil in an explosive manner when disturbed. This is dangerous as it can mean that a cup of boiling hot water may suddenly explode in your face.
  • Certain foods are known to generate sparks in a microwave. For example, when two oblique slices of chilli pepper are placed near each other point-to-point, a flame sparks between the two points from the arcing electricity. Grapes do the same thing.
  • Some foods such as grapes and eggs explode in a microwave. This is because of the pressure building up within it from all the steam being released all at once. This is amplified with something like an ostrich egg where the shell is strong enough to contain an immense pressure. But when a certain pressure is reached, the egg will literally explode and send shrapnels of microwave pieces flying out like a bombshell.
  • A piece of garlic will spin rapidly in a microwave as garlic has a thin tube running on one side. As water evaporates, the vapours rush towards both ends causing the garlic to spin. Also, if you cut the bottom of a clove of garlic then microwave it for about 15 seconds, the pieces of garlic will pop out easily.
  • As explained above, metal conducts microwaves and generates a current. This is most obvious when a CD is placed in a microwave, where sparks dance on the surface (assuming the reflective surface is facing up). Similarly, a fluorescent tube will light up in a microwave from the electricity generated.
  • Placing an open flame, such as a lit candle, inside a microwave produces a very strange phenomenon. The naked flame will become ionised plasma and shoot up to the ceiling of the microwave. This is observed as a ball of light floating around. Note that this is extremely dangerous and most likely will destroy the microwave.

Slap Bet

Posted on by Jinavie

If you ever have a disagreement with a friend and would like to bet over who is right, make the ultimate wager: the slap bet. Basically, whoever is right gets to slap the other person in the face as hard as they possibly can. On the surface it appears to be simple and harmless. But in reality, it is a deadly and formidable wager. For example, if one ever makes the unfortunate mistake of making a slap bet with the condition that the slap can occur at any place at any time, then they must live in fear of a slap appearing out of the blue and leaving a glowing, red and rather painful hand print on your face.

Being such a pricey bet, it is always useful to appoint a Slap Bet Commissioner. The Commissioner is responsible for resolving any problems that may arise regarding the bet, such as making a ruling. They must remain completely unbiased and hold the integrity of the slap bet above all else. They must also enforce the sacred rules of the slap bet, such as no premature slapulation. If the rules are disobeyed, the Commissioner has the power to endow one player the right to slap the other player (with completely subjective judgement of how many slaps they can get).

The slap bet is also highly customisable, where the players can settle on the number of slaps and the manner in which they will be delivered. Will the loser receive ten slaps in a row? Or will they get five slaps that can occur from the moment they lose to infinity?

A slap bet is the ultimate bet that is so satisfying and cathartic for the winner, but for the loser it is… well, let’s just say it is a real slap in the face.

Transactive Memory

Posted on by Jinavie

It is common to find couples, families or teams where someone always asks another member about a certain memory, while the opposite happens for a different memory. For example, a mother might always consult his son about computers and technical difficulties, while the father might always consult the mother about his plans for the month. This kind of “shared memory” is named transactive memory, where a group becomes organised in a way to share memory around in an efficient manner. This is usually done by the group reorganising itself so that each member specialises in a certain field, with the other members only remembering that that person is the expert. This means that instead of memorising every field, you can simply remember who is the expert in that field. It is much like learning where the reference text is rather than learning the contents.

Although it may look like dependence, transactive memory is an extremely useful tool in tight groups such as a couple or a small team. By having members specialise in certain domains of knowledge, the group is able to expand their capacity to acquire knowledge and create innovation. Transactive memory allows for a group to become efficient and effective in learning and retrieving knowledge. Overall, it improves decision making processes and the efficiency of the group, allowing for better outcomes. This is achieved by the division of responsibilities from specialising, shortening the time needed for finding the appropriate knowledge (as everyone knows the “guy” or “gal” to go to) and the shared understanding of the teammates regarding the interpersonal relations in the team. This means that everyone knows exactly who to go to for a certain domain of knowledge, while understanding their strengths and weaknesses, allowing for well coordinated interactions. Because of this, transactive memory only works in groups with limited numbers, with the maximum number being similar to the Monkeysphere (150).

Many studies prove the effectiveness of transactive memory. It has been found that couples have much better memory recollection compared to when they are paired with a stranger. In the modern technological era, transactive memory has expanded to the internet, with studies showing that people are more likely to know the source of information (such as Wikipedia) rather than the actual information. Given the ease of access to the internet and large databases containing all the information we need, sometimes it is far more efficient learning how to find these sources rather than rote learning all the information.

Fried Chicken

Posted on by Jinavie

Although it may be unhealthy, it cannot be denied that fried chicken is one of the most delicious foods in existence. The following is a simple recipe for fried chicken without using a deep frying machine.

Ingredients:

Chicken drumsticks x 4 (although any piece can be used)
Flour 50g
Egg x 1
Breadcrumbs 50g
Salt 1/2t
Cajun spice or paprika 1t
Canola oil

  1. Wash the chicken then season it with salt and cajun spice. It is good to rub oil on the chicken as well to keep it moist.
  2. Let the seasoning set in for about 10~15 minutes. Meanwhile, preheat the oven to 180°C and line an oven tray with tin foil.
  3. Pour the flour into a plastic zip-lock back. Place the chicken in the bag, seal it, then shake it to coat the chicken with the flour.
  4. Beat the egg then dip the chicken in the egg to coat it.
  5. Coat the chicken with breadcrumbs. You can sprinkle some thyme, oregano or parsley on top as well.
  6. Rub or spray some oil on the tin foil to prevent the chicken from sticking.
  7. Use a knife to make 2~3 deep gashes in the chicken. This helps it cook through.
  8. Arrange the chicken on the tray then put it in the oven for about 15 minutes until the top is golden.
  9. Flip the chicken over to make sure both sides are thoroughly cooked. Cook for another 10 minutes.
  10. When the outside is crisp and golden, take out the chicken and check that the inside is cooked well.
  11. Serve with some potato fries and vegetables.

OCEAN

Posted on by Jinavie

A major challenge in psychology has been the question: “how do we categorise personalities?”. There have been many different approaches, one famous model being the Big Five model. This model describes five traits, summarised as OCEAN:

  • Openness: Describes a person who is creative, imaginative, abstract and curious. People with high openness scores are often skilled in the arts and inventing. They always seek new experiences. The perfect example for Openness is Leonardo da Vinci. This trait can be subdivided into the subcategories: Imagination, Artistic interests, Sensitivity, Adventurous, Curiosity and Tolerance for diversity.
  • Conscientiousness: Describes a person who is reliable, trustworthy, hardworking, plans ahead, goal-oriented, efficient, responsible and moral. The perfect example for Conscientiousness is Robocop. The subcategories are: Sense of competence, Orderliness, Responsibility, Achievement-striving, Self-discipline and Deliberateness.
  • Extraversion: Describes a person who is chatty, energetic, passionate, stubborn, social, easily makes friends and opinionated. The perfect example for Extraversion is Eddie Murphy. The subcategories are: Friendliness, Gregariousness, Assertiveness, Activeness, Excitement-seeking and Positive.
  • Agreeableness: Describes a person who likes to help others, is compassionate, friendly, forgiving, trusting, cooperative and empathetic. It is more about humanism rather than describing a spineless person. The perfect example for Agreeableness is Mother Teresa. The subcategories are: Trusting, Sincerity, Altruism, Compliance, Modesty and Sympathy.
  • Neuroticism: Describes a person who is unstable, easily depressed or worried, dark and susceptible to negative emotions. It is not the same as “neurotic”, which describes a mental disorder. The perfect example for Neuroticism is Woody Allen. The subcategories are: Anxiety, Self-consciousness, Hostility, Self-indulgence, Moodiness and Sensitivity to stress.

When the model is applied to a person, the person gets a score as a percentage for each trait. By using the Big Five score, one can compare different personalities and predict what kind of behaviour they would show in different situations.

Common Side-Blotched Lizard

Posted on by Jinavie

Rock-paper-scissors is a fun game that is played by people of all ages and nationalities. But there is also a species of lizards that plays this game, albeit in a rather strange way.

Male common side-blotched lizards, also known as Uta stansburiana, have a mating strategy based on the game, where the chances of “winning” is equal and one type has an advantage over another type while being disadvantaged against another type. The males come in three types, differing in the colour of their necks: orange, blue and yellow.

  • Orange-throated males are the strongest but do not like to form a bond with the female (i.e. do not want a relationship). They can easily win over a fight against the blue-throated males to win the female, but yellow-throated males can sneak in and win over the female instead. Orange beats blue but loses against yellow.
  • Blue-throated males are middle-sized but do form strong bonds with females. They lose in a fight against orange-throated males, but can easily defend against yellow-throated males as they are always with their female. Blue beats yellow but loses against orange.
  • Yellow-throated males are smallest but can mimic females, letting them approach females near orange-throated males. They mate with the females while the orange-throated male is distracted, but this strategy does not work with blue-throated males as they have stronger bonds with the females. Yellow beats orange but loses against blue.

Interestingly, although the proportion of the three types average out to be similar over the long run (much like the probability of a person playing a certain hand), in the short term the preferred strategy tends to fluctuate. For example, orange-throated males may strive with their masculine strength for four or five years, but then the trend will slowly switch to yellow-throated males and their mimicking, female-stealing strategy. After another four or five years, blue-throated males will make a comeback as they win over females with their strong bonding.
