Two Clocks

There are two clocks: a still clock and a clock that is always a minute late.
Which clock is more accurate?

The answer is the still clock – it tells the correct time twice every day, but the other clock is always wrong despite the fact that it constantly ticks.
Sometimes when life gets you down, it is better to stop and rest instead of trudging on forever, always out of sync.

Trophallaxis

One of the key characteristics of social animals is the act of helping other members of the society. People often think that nature is ruled by “the survival of the fittest” and selfishness for survival, but societies are common in the animal kingdom. For example, even insects, that people consider “inferior”, such as ants build massive empires and cities, forming an unbelievably intricate and efficient society.

In the wild, all animals must find food to live, but due to competition and the environmental conditions, there are days when an animal cannot find enough food. For times like this, ants have a second communal stomach which they fill with leftover food after a meal. They then approach a hungry colony member and offers it a meal. If the other ant accepts, the two ants then lock their mouths together and one ant brings up the food in the communal stomach into the other ant’s mouth. Benefaction such as this allows for a smooth functioning of the society.

There is another role of trophallaxis (the transfer of nutrients via the mouth-to-mouth route described above): communication. Ants rub their antennae together to identify each other’s pheromones, which acts as identification such as what colony they are from and their role in the colony. Some scholars suggest that trophallaxis is the origin of the kiss.

The act of offering pre-stored food to comrades is also found in vertebrates such as birds and bats. For instance, some species of birds feed, return to its nest and then vomits the food for the young to feed on.
Helping those in need to create an efficient and functional society, and reaping the rewards of quid pro quo: that is the way of the philosophy of 1 + 1 = 3.

Eleusis Game

The victory condition for this card game, named after an ancient Greek city, is quite simple: discover the pre-determined law via induction.
This game needs at least four people, with one person acting the position of God. God decides on a certain law (in the form of a single statement) and writes it down on a paper, thus creating the way of the universe
Next, the deck of cards is split evenly between the other players, then one person places a card in the centre. After “the world begins to exist”, God looks at the card and says “This card qualifies” or “This card fails”. The next player also places a card in the centre and the God judges whether it fits the way of the universe.

Players carefully study which cards qualify or fail to try discover the way of the universe. If someone thinks they figured the law out, he or she proclaims themself as the prophet, who begins to take over the role of God to announce whether the cards qualify or not. If at any point the prophet is wrong, he is dismissed. If the prophet correctly judges ten cards in a row, he states his hypothesised law and compares it to the piece of paper. The prophet wins if the two laws coincide, but is dismissed if it is not. When all 52 cards are played without a successful prophet, God becomes victorious.

However, as this is a game, the way of the universe cannot be too complex. To make it fun, the God player must devise a law that is simple yet difficult to discover. For example, the law “Alternate a card higher than 9 and a card lower than 9” is tricky as players tend to focus on picture cards or the colours of the cards. Also, laws such as “Only red cards qualify, except the tenth and thirtieth cards are disqualified” and “Accept all cards that are not the 7 of Hearts” are illegal, as they are too detailed. A God who comes up with such ways of the universe that cannot be found using logic and the scientific method loses his right to play the game. Ergo, the God must seek simplicity that is not easily conceived.

So what is the most successful strategy for this game? Even if there is the risk of being dismissed, proclaim yourself as the prophet as soon as possible for the best chance of winning.

Cognitive Dissonance

When two conflicting ideas exist at the same time in the human mind, it causes uneasiness and discomfort. Human beings instinctively tried to reduce the dissonance, most easily achieved by adaptation and blaming. For example, when a person wants something strongly but cannot attain it, they choose to believe that they do not want it any longer, discarding one idea to dissolve the dissonance.

A famous portrayal of this condition is Aesop’s fable The Fox and the Grapes, which goes as following:

A fox sees a grape on a tree and wants to eat it. However, the grape is too high up, so the fox says “That grape is surely sour.” and turns away.

This fable shows the classic pattern of: Wants something -> finds it unattainable
-> criticises it to reduce their want, and ultimately the dissonance caused by it.

This effect is quite powerful and explains many of mankind’s unique behaviours. As stated above, people try to reduce the dissonance by justification, denial and even blaming a third party to ease their mind.
Interestingly, the act of “justification” is brought on by another human feature: arrogance. Most people consider themselves intelligent and always making the right decisions, ergo when they make a mistake it conflicts with their self-image. Instead of accepting that they made a mistake (thus altering their image), they instead believe that they intended that action. This belief is so strong that they do not even know the justification happened subconsciously.

For example, there is a phenomenon called buyer’s remorse, where a buyer finds a flaw or a better product after buying something, feeling remorse (which is due to the discomfort caused by cognitive dissonance). Instead of blaming themselves, people will justify their reasons for buying that product, and paradoxically value that item even more. This shows how cognitive dissonance can be seen everywhere in everyday life.

In short, people cannot accept paradoxes, believe they always make the right decisions, and twist reality and make excuses when it does not fit what they desire. People are fascinating.

Mayday

Mayday is the universal phrase for requesting emergency assistance in a crisis situation on the sea or in the air. 

It was first created by Frederick Stanley Mockford, who was a senior radio office trying to figure out a simple distress call sign. As he worked at Croydon Airport, London, and dealt with traffic mainly between England and France, he decided on the word mayday, which is derived from the French words venez m’aider, meaning “come help me”.

Another famous distress call is SOS, or  … – – – … in Morse code. It was first used by German radios but then became the worldwide standard in 1906. Although it is often thought to stand for “save our souls”, it is in fact a backronym that was made decades after it came to be. Instead, it was chosen as it is simple to remember (the backronym may have been devised to help people remember the letters) and easy to signal via Morse code. It was most famously used by the RMS Titanic

The reason why mayday was created (and set as a standard in 1927) was due to the need for a spoken word as the audio radio transmitters were developed.

Feynman Problem Solving Algorithm

Richard Feynman is a world-renowned genius physicist, famous for his ability of solving some of the most difficult problems in physics. He said that his intelligence was all thanks to his unique yet “normal” problem solving method, which he used to solve most of his problems. Here is the algorithm:

    1.  Write down the problem.
    2.  Think very deeply.
    3.  Write down the answer.

If that does not yield the answer:

    4.  Sleep.
    5.  Wake up, then think deeply again.
    6.  Write down the answer.

Nothing is impossible.

Cranial Nerves

Nerves can be divided broadly as spinal nerves and cranial nerves: the latter which is directly from the brain. There are 12 pairs of cranial nerves:

  1. CN IOlfactory nerve (smell)
  2. CN IIOptic nerve (sight)
  3. CN IIIOculomotor nerve (eye movements, control of pupil and lens)
  4. CN IVTrochlear nerve (eye movements)
  5. CN VTrigeminal nerve (sensory information from face and mouth, chewing)
  6. CN VIAbducens nerve (eye movements)
  7. CN VIIFacial nerve (taste, tear and salivary glands secretion, facial expressions)
  8. CN VIIIVestibulocochlear nerve (hearing and sense of balance)
  9. CN IXGlossopharyngeal nerve (taste, swallowing, parotid gland secretion, sensory information from oral cavity, information about blood)
  10. CN XVagus nerve (sensory and motor signals to and from many internal organs, glands and muscles)
  11. CN XIAccessory nerve (movement of SCM and trapezius, which are neck/shoulder muscles)
  12. CN XIIHypoglossal nerve (tongue movements)

As there are so many nerves and the names are all varied, there is a simple (yet very obscene) mnemonic to help medical students remember the names and order of nerves:

Oh, Oh, Oh, To Touch And Feel Virgin Girls’ Vaginas And Hymens
or
Oh, Oh, Oh, To Touch And Feel A Girl’s Very Soft Hands
(where vestibulocochlear -> auditory)

It is also worth noting the mnemonic for the types of nerves is:

Some Say Marry Money, But My Brother Says Big Boobs Matter More

Perhaps the only way to survive medical school is through humour.

Alice In Wonderland Syndrome

There is a disease called Alice in Wonderland Syndrome. This causes patients to suffer massive migraines, while suffering visual hallucinations that alter their perception of what they see.
For example, they see objects as bigger or smaller than what they actually are, or even see them as upside-down. Because of this, people who have experienced this syndrome say that it was like living in a fairy tale. There is no known cure, but it is often temporary and will one day disappear like magic.

When you fall in love, the other person’s weaknesses seem smaller, their strengths seem bigger, and sometimes they turn your world upside-down. So is love like living in a fairy tale, or like suffering a disease?.

Pope Joan

There is a legend in papal history regarding a certain Pope John VIII, who is believed to have reigned between 853 – 855 AD. The reason this pope is so famous is that legends state that “he” was in fact a woman, making her the first (and only) female pope in history.
Legend has it that she was a very talented and intelligent woman who, with the help of disguising herself as a man as education was forbidden to females in those times, quickly rose in the church hierarchy to eventually become the pope. After a couple years of power, her true sex was discovered when she gave birth to a child one day.

There is reasonable evidence of her existence, ironically through the extensive cover up of her existence by the church. After finding out that she was a woman, history tried its best to forget the fact by constantly removing evidence of her existence. For example, in the 14th century a series of busts of past popes were made for the Duomo of Siena, one of which was named “Johannes VIII, Foemina de Anglia”, suggesting a female pope by the name of John VIII.

It is possible that she managed to deceive people of her gender by having a form of adrenal hyperplasia, which would lead to her having abnormally high levels of androgen during development. This would lead to ambiguous secondary sex characteristics, such as facial hair, androgynous appearance and possibly even an ambiguous genitalia (but of course she would have had a mild form as she was able to conceive and birth a child).

Pope Joan had a significant impact in papal traditions. Two which are famous are the change in the papal procession path and the sedia stercorania. 
The childbirth scene that exposed her occurred during a papal procession, whilst passing a narrow lane. That lane is no longer passed after that event occurred.
The sedia stercorania is a chair with a hole in it that was used to install new popes. The reason for the hole was so that a junior cardinal could reach below the chair on which the pope was sitting on, and check whether he had testicles, after which he would announce: “Duos habet et bene pendentes” (he has testicles and is well hung). This became a compulsory examination after the scandal of Pope Joan.

Gaze

A gaze is defined as “to look fixedly, intently, or deliberately at something”, but its true meaning is far deeper than that. In art and psychology, the “gaze” is described as a complex medium of communication between the subject and the object being gazed at. There are many theories as to what the gaze signifies.

A popular explanation is the exertion of dominance by the subject by gazing at an object. In essence, this act objectifies something, such as a painting or a person, placing it on an inferior level relative to the observer. This applies to the concept of the “medical gaze” – where the doctor can see the patient as just an anatomical body, or a holistic being with a soul – or the “male gaze”, which feminists claim to be the tendency for films to objectify women and play to the male audience, providing them with the power and dominance. In this case, the gaze acts as a projection of the viewer, placing himself as a dominant figure indirectly interacting with the female being gazed at in the movie. Although the male gaze itself is questionable, there is no doubt that people tend to project themselves into the characters in a movie through gaze.
This theory explains the uncanny feeling brought on by a gaze, as it gives the impression that you are being defined by someone’s gaze, whilst becoming dominated.

The gaze plays a vital role in the development of babies as they pass through what is called the “mirror stage”. This is when babies first conceive the idea of self, as they see an external image of themselves in the mirror. At this point, the baby’s gaze defines the external image (reflection) while the reflection’s gaze gives the baby an uncanny feeling of “self”.
The concept of the gaze has been well-known throughout history, and is reflected in myths such as the evil eye (that brings bad fortune to those being gazed at) or Medusa (the gorgon who petrifies those who make eye contact with her). Interestingly, the story of Narcissus shows the danger of gaze by misidentifying “self”.

Artists use this concept of gaze effectively by either letting the audience simply gaze at the picture, essentially letting it be defined only when being looked at, or invite the audience in a “conversation” with the painting. This can be achieved when characters in the painting are gazing at the audience, giving the illusion that they can actually see past the two-dimensional plane, gazing into the viewer’s eyes. This produces a strange feeling, while also giving the viewer a heightened appreciation for the painting as he/she feels at level with the painting. 
Furthermore, as the gaze is a two-way conversation, there are also examples of “setting oneself at gaze”. This means that they are exposing themselves to be gazed at, a common example being nude art. Of course, this ties into voyeurism and scopophilia, showing just how complex the meaning behind the word “gaze” can be.
