Time Divided

Posted on by Jinavie

Even though time is continuous, we like to think of think of time in segments.

The most basic unit is the year. Every time the Earth rotates once around the Sun, we take stock of the year gone by, while setting resolutions for the next year. Technically, whether it is 300 or 400 days, time has passed, yet we always mark changes by the number of years. For example, we use age as a marker of what stage of life we should be at (even if it is not a very accurate marker).

Another classic example is the four seasons. The making of accurate calendars and units of time was critical in the development of agriculture as it allowed us to plant many different crops with high efficiency and yield. In older times, people may have marked time by reminiscing what happened around the time of the last harvest while eating food made with ingredients harvested at that time.

Some segments are less regular, such as the last time you caught up with someone, or whenever you have a big life change such as moving cities. Some people may mark the chapters of life by the person they were dating at the time, or the stage of professional development, such as what year of university they were in.

Why do we obsessively divide time and remember our lives in artificial, bite-sized chunks? Our brains are very good at noticing patterns and change, but not so good when the changes are gradual and continuous (change blindness). Ergo, dividing up time into segments help us process the past.

It is hard to notice how much someone’s hair has grown if you see them every day. It is hard to notice how different you and your partner have become with time until a conflict arises. It is hard to notice how much we have grown and matured and changed without consciously reflecting from time to time.

Another interesting thing to consider is that what you use as a marker of time may suggest what you are prioritising. When you look back, what is the unit of time you use to divide your life? Is it the last time you moved cities? Your last boyfriend or girlfriend? Your last big trip? A moment where you came to an epiphany?

Whatever it is, it is a useful practice to periodically look back on all the segments that make up your life, such as by keeping a journal and reading it later. This will let you be more aware of how you are developing as a person and help you steer yourself in the general direction that you want your life to take you. At the very least, it is amusing to notice the subtle differences between the past and the present you.

Reflection

Posted on by Jinavie

The end of the year is as good a time as any to reflect on the days that have been and who you are now. Time to reflect is hard to come by, as life keeps us busy and on our feet constantly. But that is not enough of an excuse. We are defined by our experiences and connections, meaning that we are constantly changing to some degree. If we do not reflect, we cannot learn from our mistakes, or know what direction we are heading in because we lose sight of what we need or what is truly important to us.

Reflections can take many forms and everyone will have their own preferred style. But if you are not used to it, try the following method. If you cannot recall the last time you truly reflected on yourself, then you should definitely give reflection a try before greeting the new year.

First, consider the past.

What were the highlights of the year? When were the moments you struggled through? What relationships were made, changed or broken? This is an important step as we take inventory of all of the experiences, emotions, connections, hardships and things we learned – that is, the ingredients that you are made of. Only then can we process how these things affected us.

A loss or an ordeal may traumatise us, but they make us more resilient as we remember that despite the grief and stress, we survived. Wonderful memories remind us of the things we should be grateful for. Moments that we are proud of remind us how much we have grown. If we do not reflect on the past, you might as well have wasted the year, because it would not have added to your life in any way.

Second, consider the present.

How are you feeling right now? Are you miserable and confused, unsure of who you are and where to go from here? Or are you content and happy with how things are going? How is your relationship with your loved ones and, most importantly, with yourself? What concerns hang around in the back of your mind? What kind of person are you right now, and is it the kind of person you wanted to become? What is most important to you at the moment?

The present is a fleeting moment between the infinite past and future, but it is just as important, because we live in it. This is who you are. Too often, we are so preoccupied by our past mistakes or grand dreams of the future that we lose track of who we are right now. Make sure you have a good understanding of the present you, so that you have a solid anchor for your future self.

Lastly, consider the future. You don’t have to have the rest of your life planned out, but it is always good to have some idea of the general direction you want to head towards in the coming year. What are the things you want to leave in the past? What are the things you want to carry forward, or improve upon? What are some things you are looking forward to? What changes should you be making for your happiness? What kind of person do you want to grow up to become?

The future is wild and unpredictable. We cannot possibly know what surprises await us there: happiness, sadness, madness, death. So there is no point being anxious or afraid of the future. All we can do is be prepared by having the skills and resilience to survive through whatever the future may throw at us. Hopefully, it will be an enjoyable ride.

If this is too difficult to do just in your head, try writing a letter to two people: you from the start of this year, and you from the end of next year.
To your past self, tell them the stories from this year, the person you have become and how they will be alright.
To your future self, tell them to leave your bad habits and worries behind, while moving forward with the good connections and positive habits you have cultivated. Writing things down is a good way to process these complex reflections.

At the end of the day, it does not matter how you go about it, as long as you have given some thought about your life. Life is not a movie that we watch from a couch with a bowl of popcorn. It is your personal adventure full of decisions, actions and consequences. We cannot let it pass by like a TV show. Instead, we need to be conscious of the role we play in our own lives and actively try to make the most of it.

Happy New Year.

Silver

Posted on by Jinavie

Historically, silver has been associated with cleansing, healing, the moon and warding off evil. For example, it is said that some monsters such as werewolves would only die if it is shot by a silver bullet. The Greek goddess of hunting and the moon, Artemis, carries a silver bow. Although it is always seconded to gold when it comes to precious metals, silver is a fascinating metal.

It is the most reflective metal on Earth and has the highest conductivity for heat and electricity. It is ductile and malleable, making it a good choice of metal for making coins, jewellery and silverware (hence the name). Because of how reflective it is, it is also used in solar panels and special mirrors, such as those in telescopes.

Another useful characteristic of silver is its chemical reactivity. Thanks to this property, silver forms many different compounds with varying applications. Silver halides are photosensitive and turn dark when they are exposed to light. This is the basis of film photography, where the light shone on a film coated with silver halides leaves a photographic imprint. Silver oxides are sometimes used in batteries and silver/mercury alloys are used for dental fillings.

Silver also plays a role in medicine. Silver ions have been shown to inactivate bacteria such as E. coli, making silver nanoparticles a useful antiseptic that can be impregnated into different materials such as wound dressings. Silver nitrate sticks are used in emergency departments as applying it to a bleeding vessel in the nose will release nitric acid, which cauterises (burns off) the vessel to stop a nosebleed. In medieval Korea, silver spoons were used to test if a food has been poisoned with arsenic, as arsenic reacts with silver to form a black tarnish. If a person has too much silver build-up in their body, they can develop argyria (silver poisoning), which turns the skin an eerie bluish-grey colour.

Mirror

Posted on by Jinavie

Mirrors are perhaps one of the most useful yet underrated inventions that we use every day. From shaving in the morning to fixing make-up during lunch, the modern man or woman will use a mirror (or some other reflective surface) at least once a day. Mirrors show us an accurate reflection of the world that we cannot see. We can only look forwards and need a mirror to reflect light going the opposite way to see behind us or – more importantly – ourselves. To do this, a mirror must directly reflect every photon (particles that make up light) at exactly the right angle so the image is not distorted. If the mirror is not completely flat or perfectly polished, light will not be reflected at the exact angle and we will see a distorted image – much like looking into a mirror at the circus. Therefore, one could say that a perfectly flat, clean mirror is absolutely honest, as it will reflect exactly as it sees.

However, this statement is not entirely true as what you see in the mirror is a mirror image of reality. This may seem trivial, but it has significant consequences. This is most obvious when you hold a book up to a mirror. Without training, it is very difficult to read something that is mirrored. This is why Leonardo da Vinci wrote his notes in mirror image. This phenomenon of something becoming completely different is also seen in chemistry. Because of the way molecules are arranged, it is possible to have a property called chirality – where two molecules with the same elemental composition are built in the mirror image of one another. Essentially, it is as if the molecule can be either left- or right-handed. It turns out that even if the composition is the same, two molecules of different chirality (called enantiomers) can act completely differently. This effect may be as simple as changing the way a liquid polarises light to making a drug completely inert or even toxic. For example, the amino acid carvone that gives the spearmint taste only tastes like spearmint if it is L-carvone (“left-handed”), whereas D-carvone (“right-handed”) is tasteless despite having the same molecular formula.

Since the topic of chirality is rather technical and hard to understand, let us move on to the field of literature. One of the best examples of how mirrors can completely change something is seen in Lewis Carroll’s novel Through the Looking-Glass and What Alice Found There. Lewis Carroll understood the significance of mirror images in chemistry and wrote this novel to portray how quirky and strange a “mirror world” may be. Through the Looking Glass is a sequel to the famous book Alice in Wonderland and describes a world that is the mirror image of Wonderland. Carroll cleverly wrote the first book so that it would be the opposite of the first book. The first book starts outdoors, is set in the summer, uses changes in size as a plot device and focuses on the theme of trump cards. The second book starts indoors, is set in the winter, uses changes in direction as a plot device and draws on the theme of chess. There are even characters such as Hatta and Haigha who are the mirror images of the Mad Hatter and the March Hare from the previous book. Although they are very similar, they are just not the same and hence Alice does not recognise them. Perhaps the line that best shows Carroll’s understanding of the dangers of mirror worlds is this: “Perhaps Looking-glass milk isn’t good to drink”.

The field of psychology is also heavily interested in mirrors. It is a well-known fact that our brains recognise the purpose of mirrors. If you put a mirror in front of someone, you know that the person will examine themselves, groom themselves or simply make funny poses. A simple experiment shows how used to mirrors we are. If you angle two mirrors at right angles and fit a transparent sheet of glass in front of the two to make a prism shape, the image you see through the glass is a reflection that is not mirrored. Because it is not mirrored, you can hold up a book to it and still read it fine. This is known as a non-reflecting mirror. An interesting experiment shows that if you make people use this kind of mirror, they become incredibly confused as they are too used to using a mirror image to see themselves. Even though the reflection they see is a “truer” image, because their brain automatically flips the mirrored image, they become uncoordinated and keep moving their hands in the opposite direction.

As mentioned at the start, mirrors are a human invention. Although reflection occurs in nature, such as on a clear surface of water, animals generally are incapable of using mirrors. This is such a universal fact that animal psychologists use a mirror test to determine whether a specie of animal is self-aware or not. The test is done by showing an animal a mirror. Most animals will see their reflection and automatically believe that it is another animal, as they are incapable of thinking that it is a reflection of themselves. Hence, they will try to threaten, attack or flee from the image they see. But if you show a higher-order animal such as an ape or dolphin a mirror, they will start to groom themselves as they realize that the mirror is simply showing themselves.

This is what sets us apart from animals. Not only are we capable of recognizing ourselves in a mirror, but we have the ability to go one step further and reflect on ourselves using the mirror of our minds. Some people may take a look at the person in this mirror and be content with who they are. But some will gaze into the mirror and, much like the animals in the mirror test experiments, see a completely different person they do not recognise. This may cause disappointment, frustration or even disgust as we realize that we are not who we think we are or aspire to be. Then again, sometimes you will gaze into the mirror and see a person that has strengths such as courage – a person you could be if you realized your true potential. The most frightening realisation would be to discover that there is no one in the mirror.

Lastly, we could consider the mirror of behaviour. Goethe said that “behaviour is a mirror in which everyone displays his own image”. The corollary to this is that human beings read behaviour to try and interpret another person’s character. One can use this to greatly improve the relationship and connection with another person. Mirroring is the act of subtly copying the other person’s behaviour to build rapport – where an empathic bridge is constructed between two people. Rapport is particularly useful in jobs that involve earning the trust of strangers in a short time, such as in healthcare or business. By matching the other person’s body language, such as posture or actions like taking a sip of water, the other person will open up more easily to you. The same applies to verbal and emotional mirroring where you subtly reuse the words the other person spoke and reflect their emotions such as excitement. Obviously, one must be subtle with mirroring as a direct imitation will appear mocking and strange. If you are able to subtly copy their behaviour, the other person’s subconscious mind will be tricked into thinking that you are similar in character and trust you more. This skill is extremely useful in improving your interpersonal and social skills.

A mirror is a paradoxical object that is absolutely honest yet relatively deceitful. Reflections in the mirror are true yet completely different. If you take a peek into the mirror of your mind, perhaps you will see the person you think you are now or the person you could be in a mirror world. If you are happy with what you see, then cherish that and be proud of who you are. Otherwise, you can always do what Alice did and jump through the looking-glass to find an alternate you – the best you that you can be.
