The beauty in symmetry

Have you ever wondered why you are sometimes attracted to some piece of art, and not to the other? Or why you find something visually appealing while another almost repulsive. Well next time, you do find yourself in such a situation, just take a moment, and see if what you are staring at, is symmetric or not. If you like it, chances are that the piece of work is very symmetric. Studies show that, when given an option to choose between symmetric and asymmetric pictures, people are more likely to choose symmetry over asymmetry. And this phenomenon is gender independent, so whether you are man or a woman, you will pick symmetry where possible

If we look around, we find that symmetry seems to be a very important part of nature almost like a rule. Every organism is an example of symmetry, right from viruses that show radial symmetry, to fruits and flowers that have perfectly aligned parts, there is symmetry everywhere. Biologists believe that symmetry is nature’s way of displaying fitness and superior genes. 

We are not immune to this rule 

Interestingly, we also hold similar scales to judge the attractiveness and beauty of people. Like art, people are more likely to select a face that is symmetrical, as beautiful, over an asymmetric face. In fact studies show that people with symmetric face are more social, extroverted, agreeable, and positive.

This subconscious obsession of ours is deeply embedded into our systems; our fascination for symmetric faces can be traced back to a study done on infants. It is understandable that infants would choose familiar faces over unfamiliar ones. But when asked to choose between unfamiliar faces, infants tend to choose symmetry over asymmetry, meaning facial features that are more symmetrical than those that aren’t.

While symmetry may be our cue to finding healthy genes or person with good social skills, the question to be asked would be why is that we do not asymmetric faces appealing. 

To answer this, researchers at the Ohio State University conducted a study and found that individuals who had more asymmetric features were more likely to be aggressive, and impulsive, in comparison to those that were symmetric. Also, asymmetry is a good indicator for environmental and developmental stress. e.g. Fluctuating asymmetry is an indicator of alcohol abuse, or other substance abuse by the mother during pregnancy.

This tendency of ours to choose symmetry over asymmetry is best exploited by the film industry. 

But all this talk about symmetry and asymmetry, the interesting part about it is that,  experimentally, it is very difficult to break symmetry.  Deviating symmetry is nearly impossible in a laboratory setting, in fact breaking symmetry in fruit flies was impossible. 

We all are invariably attracted to very proper, neat and calculatedly symmetric features. However, predictable and horribly prone to our natural instinct it may sound, we are in the end of it all, attracted to symmetry and artists, photographers often exploit this very weakness that is deeply embedded into our genome.

Do free energy magnetic motors really work?

The internet is rife with websites that promote generators that are capable of providing electricity without using any fuel. Built largely with magnets, these 'free energy generators' promise to cut your electricity bills and provide a much greener alternative to the electricity that is largely generated out of fossil fuels. Elaborate videos that give you estimates of how much money you can save without revealing any details of how to go about it, manage to keep the audience hooked on for a while, but $40 price tag, the loads of freebies and the instant $10 discount for not leaving the page, make the product and its seller highly suspicious. So, we decided to find out if these free energy magnetic motors really work?

The Principle

The magnetic motor works on the simple principle that we all already know, 'Like poles repel each other while opposite poles attract each other'. By arranging the magnets in a fashion where only like poles face each other, one can simply set t…

Why Sci-Hub’s story is so crucial to science?

On the 28th of October 2015, Judge Robert Sweet in his ruling at the New York district court declared that the website be blocked with immediate effect and managed to stop hundreds and thousands of researchers and science enthusiasts from accessing the holy grail of today’s science, the research paper.
What should be a simple means to communicate to the world one’s research findings, has become a currency of some sort. A ticket to a researcher’s professional success, a magnet for an investigator to attract funding for his lab and the elusive piece of the puzzle that the publishing group can hold you ransom for, until you cough up some good cash ($30 or above for a single article and thousands of dollars for a bundled annual subscription)
What Judge Sweet termed as a “disservice (to) public interest”, is actually a small website that allows you access to scientific research, old and new, and for free. Sci- Hub. Org, started in 2011, as a trusted place to access research …

Generating electricity from flapping tree leaves

As kids, you might have spent many afternoons, under a huge tree, enjoying its shade. In a tropical country like India, trees are a welcome sight in the month of May, when the sun is blazing in the sky and the shade offered by them is a hundred thousand times better than artificial cooling of the air conditioning units. But never in our dream would we have thought that the rustling of the tiny leaves of the trees could one day make electricity for us.Because that requires a Hendersonian moment! (just in a bit)

This brilliant idea has come from the lab of a biophysicist at Iowa State University, Dr. Michael McCloskey, whose work at the University largely involves the study of membrane transport in algae and adult born neurons but also has a background in plant sciences. It was his colleague in the department of genetics, Dr. Eric Henderson who first came up with this plan of harvesting energy from leaves as he wondered how much kinetic energy was being generated when winds blow across l…

5 things driverless cars will do to change our future?

The race for building the world’s first commercially available driverless car is on. Google seems to be leading the pack and in its own charismatic style has been very open about it. Elon Musk’s Tesla is considered the second best with their cars having almost automated the driving process. Tech favourites, Apple also seem to be in the race but everything is under wraps, as of now, and there is not even a hint of what Apple is planning to make, the car, the software or simply make the car accessible with your Apple ID.
Once part of science fiction, driverless cars will soon be a part of our lives and with major automobile manufacturers such as General Motors, Toyota, Ford investing in the technology, prototypes of driverless cars will soon be seen on the roads. Before we get there, a quick review.
The Driverless car
The concept of automated driving has been around for close to a century but progress was slow due to unavailability of technology. For a car to be autonomous, it needs to kno…

Solar cells that work in rain

In case you have read my last month’s guest post about harvesting solar energy in rust, you would be delighted to know that there has been yet another breakthrough in our attempt to harness solar energy.  For many years, solar energy has been targeted for being unavailable at night and during rains. The problem of utilizing solar energy at night can be resolved with the help of metal oxide cells as elaborated in my above post (do read it, if you have not done so already). And now researchers at the Ocean University in China have addressed the second problem and developed solar cells that can actually use rain drops to generate electricity.
Published in the German journal Angewandte Chemie, the paper titled, A Solar Cell Triggered by Sun and Rain, opens a new realm of possibilities when harnessing solar energy. Coating the solar cell with a thin film of graphene allows the cell to function even when it is raining. Graphene is nothing but reduced form of graphite that consists of a hone…
