The Golden Ratio

The golden ratio is a special number that is approximately equal to 1.618 and is symbolized by the Greek letter Phi.  It  has fascinated scientists for years and is found hidden almost everywhere on earth. The ratio was actually derived from the Fibonacci sequence, which looks something like this: 0, 1, 1, 2, 3, 5, 8, 13 and so on. Each number is just the sum of the two numbers before it, and it looks quite simple. However when examined in depth, mathematicians and scientists realized it seems to be hiding a secret to the universe.

The Fibonacci sequence is named after Leonardo Fibonacci who actually came up with the sequence when calculating the mating sequence of rabbits over the course of one year. The sequence itself doesn’t look special at all, but when you take each number in the series and divide it by the previous number, the ratios began to  approach 1.618 as the numbers get bigger. That number is now known as “The Golden Mean”.

An example of where the golden ratio is found on earth is in the Pyramids. If the base of the pyramid is considered to be 1 unit, then its sides are calculated to be 1.618 units and the height is the square root of 1.618 units tall. The golden ratio is also frequently found in nature, particularly in flowers and trees. For example, the number of petals in a flower follows the Fibonacci sequence: Lily has 3 petals, buttercups have 5 petals, and chicory has 21 petals. All of the number of petals in different flowers are all just numbers found in the Fibonacci sequence. Each petal is placed at 0.618 per turn to allow for the maximum exposure to sunlight. In addition to that,  the number of seeds in a sunflower is arranged in a spiral shape and when the spirals are counted, the total also matched a Fibonacci number.

Similar patterns are found in  fruits and vegetables such as pineapple and cauliflower. Shells, spiral galaxies and hurricanes also seemed to contain the golden ratio when  put into a “golden rectangle”. A golden rectangle is a rectangle whose side lengths are in the golden ratio.

Last but not least, the golden ratio is found also in the human face.  People whose face proportionality approached 1.618 are deemed more attractive- although every person’s body is different, the average across different populations still tend towards the golden ratio.

THE DARKSIDE OF COSMETICS

Makeup!

Makeup is something that most women and some men are familiar with. For some individuals makeup allows them to express their creativity with the colours they choose and the various ways of application. For others, it provides an extra oomph of self-confidence. It also helps with accentuating one’s natural “beauty”. As well as, makeup allows for covering up unwanted blemishes and flaws that take away. Although “makeup” has these pros, it does come with some concerning cons.

One major con is the chemicals that are incorporated within the products. Besides the chemicals, another downside is that makeup does not allow skin to breathe freely as it plugs pores. Back to the chemicals. Most makeup products contain parabens and phthalates. These chemicals allow for “blushes”, “eyeshadows”, “lipsticks”, and “foundations” to remain fresher for longer due to their preservation qualities. Seems like that would be beneficial for consumers as their products would not go bad as fast and thus not buying products that often. In reality, parabens and phthalates are more harmful than helping save a few bucks. These chemicals have been tested and have led to many problems such as skin irritation, interference with sex hormones in both males and females, and most shocking, cancer.

A study led by Dr.Dabre, found that the penetration of parabens through the skin led to breast cancer. From this study that included 40 patients, all 40 of the women tested positive for at least one type of paraben found within their breast tissue. This one study may not cause one to think that it is that significant as only 40 patients were tested, but more scientific research is being done to see what other potential harms could arise from chemicals contained within “cosmetics”. Therefore, pre-cautions such as using less or no makeup at all can help with avoiding the dark side that comes from within “makeup”. So the next time you decide to put on some “lipstick” before you go out, think twice about what other chemicals you are putting into your body.

Is Yoga the Solution for Insomnia?

 

Has University life turned you into an insomniac? Many University and college students claim to suffer from insomnia, also known as a sleeping disorder. I’ve come across friends tweeting late at night with hash tags “insomniac” or “sleep-deprived” every so often. With the juggle of schoolwork, exercise, work and a social life, it is not surprising that a number of students are having difficulty sleeping. I personally feel that my mind is constantly working and thinking about things I need to do, especially at night when its time for bed.

Is there a cure for insomnia? Many over-the-counter or prescription pharmaceutical drugs such as sleeping pills are available and can do the job for you, but is it the right solution? There are always side effects when taking any type of medication and as a student; you don’t want to be relying on drugs in order to get a decent night sleep.

Sat Bir S. Khalsa, a researcher at Brigham and Women’s Hospital at Harvard Medical School, performed a study on subjects with insomnia and found that after eight weeks of breathing, meditation and asana exercises, the participants showed improvement in their sleep time and quality of sleep.  This research also showed that by practicing yoga for 30-40 minutes, people fell asleep 30% faster and their night-time waking was reduced by 35%.

Yoga can be portrayed as a complicated practice, with all its different poses and techniques. However, it can be as simple as just breathing. An example of a breathing exercise is alternate nostril breathing. We tend to breathe mainly out of our right nostril when we are stressed out.  The right nostril connects to the left-brain which activates our sympathetic nervous system, responsible for our fight or flight response. The sympathetic nervous system and stress hormones such as adrenaline and cortisol increase blood pressure and heart rate during stressful situations. In contrast, the parasympathetic system slows the heart rate and lowers blood pressure allowing one to recover from an overwhelming situation. Yoga poses can increase blood circulation and slow breathing can increase the oxygen level in the body. Both of these practices can increase the activation of the parasympathetic nervous system allowing for mental relaxation. This stimulatory effect of yoga on the autonomic nervous system, can help your sleeping pattern.

The video below gives a brief recap of how yoga can help you get a better nights sleep and introduces some basic yoga poses.

So next time you’re laying in bed having difficulty sleeping, try out a yoga pose or breathing exercise. It might just help you sleep like a baby!

Do you have Trypophobia?

Trypophobia is an irrational fear of holes. Many people have never heard of the word trypophobia, but a simple search online will tell you that it is actually quite a common fear. We are surrounded by holes in our daily lives, such as the pores on our skin or the holes on clothes, but no one really has a fear of those. Trypophobia does not mean the fear of any hole, but refers specifically to a cluster of holes. Many things found in nature such as honeycombs, and lotus seed pods may strike a feeling of disgust in some people.

However, there has been debates going on about if trypophobia is a real phobia. A study was done by two researchers who monitored the brain activities of patients using an image scan and found extreme brain activities whenever the participants saw an object with a cluster of holes. Many scientists still disregard trypophobia as an actual phobia because they believe people just feel discomfort based on what they see, and are not experiencing actual fear. A phobia by definition is an extreme or irrational fear of or aversion to something. Meanwhile, other scientists believe that people are just influenced by others who have some discomfort when seeing clusters of holes and end up believing they as well have trypophobia

 

Although scientists are not quite sure about the cause of trypophobia, they have hypothesized that it may have an evolutionary basis. They compared pictures of clusters of holes and found that it resembled spots  found on poisonous animals.   However, trypophobia is still not very well known, so more research must be done in order to come to a conclusion.  Currently, it is not considered to be an official phobia by many Psychological associations and is not written in books regarding mental disorders.
