Having some fun on ‘Look for Circles Day’

Today, they say, is Look for Circles Day. The idea of the day, aimed mostly at entertaining the young ‘uns, is to see how many circles you can spot. We come across hundreds of circles each day, so in addition to the obvious ones, try to look for circles in unexpected places, and even look for implied circles (where objects occur, or are placed, in such a way that they form a circle).

Look for Circles Day is a great opportunity to entertain kids of all ages with one of the most interesting shapes in nature, and to teach them some maths and geometry in the process. Here are some interesting circle facts:

• A circle is an infinite set of points on a plane that are all the same distance from a specific, predefined point.
• Of all shapes with a given perimeter, the circle has the largest area. Or to put it another way, circles have the minimum possible perimeter for a given area.
• They are the only single-sided shape with an area.
• A circle with an infinitely large radius is a straight line (there’s a hint to give you the upper hand when searching for circles!)
• A circle can be split in two identical halves in an infinite number of ways, or stated more formally, a circle has an infinite number of lines of symmetry.
• The circumference and perimeter of a circle are related through the mathematical constant pi, or π – a very interesting number in itself, as we discussed previously.
• A solid circle is a wheel, and we all know what useful invention the wheel was!
• Apparently, according to research done by the Max Planck Institute for Biological Cybernetics in Tübingen, when we have no way to navigate – for example in a thick fog, or a moonless night – we tend to walk in circles (literally).
• There is a form of divination called ‘gyromancy’ where people are made to walk in a circle until they fall down from dizziness, and the location where they fell is then used to predict future events.

Yep, as I said – circles are amazing things… Happy circle spotting!

World Smile Day: Do an act of kindness. Help one person smile!

Today, being the first Friday of October, is World Smile Day. The idea for the day comes from Harvey Ball, artist from Worcester Massachusetts USA, and the guy whose claim to fame is the creation of the iconic Smiley Face in 1963.

As the smiley face gained popularity, Ball felt it lost its original meaning. This resulted to the creation of World Smile Day – the smiley face shows no discrimination in terms of politics, geography or religion, and Ball felt that, for at least one day a year, we should put aside our prejudices as well. World Smile Day asks of you to “Do an act of kindness. Help one person smile!”

When Ball died in 2001, the Harvey Ball World Smile Foundation was created in his honour. The foundation, whose slogan is “Improving this world, one smile at a time”, remains the official sponsor of World Smile Day activities in Ball’s hometown.

On the subject of smiling – earlier in the year, on SCUD Day, I wrote a blog post about the psychological benefits of smiling, and how even just pulling your face into a smile can ‘fool’ you into feeling better.  It seems, however, that the benefits of smiling does not stop there.

I found an excellent article on the Forbes website, where Ron Gutman, founder and CEO of HealthTap, discusses many of the scientifically researched benefits of smiling. Here’s some of the results I found particularly interesting:

A 30-year longitudinal study done at the University of California Berkeley measured smiles of students in old yearbooks, and used this to predict future happiness – how happy their marriages would be, how well they would score on standardized well-being and happiness tests, and how they would inspire others. It turns out, perhaps not surprisingly, that the widest smilers in college turned out to be the happiest people in life.

A similar study at Wayne State University looked at baseball card photos of Major League players from 1952, and found that the span of their smiles served as a fairly accurate prediction of life-expectancy! The non-smilers lived to an average age of almost 73, while the smilers on average made it to almost 80.

Smiling is one of the most basic, and most universal, human expressions. In cultural studies on Papua New Guinea’s Fore Tribe, who had no contact with western culture and is known for their cannibalism, it was found that even in that very remote culture smiles were used very similar to how we use it.

Studies done in Sweden show that other people’s smiles suppress the control we usually have over our own facial muscles, causing us to smile involuntarily. Apparently it is also very difficult to frown when looking at someone smiling.

And here’s the clincher – according to a UK research study, it was found that a smile could generate an equivalent amount of ‘feel good activity’ in the brain as 2000 chocolate bars!

Have a look at Gutman’s article – it’s a most amusing read.

Have a brilliant World Smile Day, everybody. I think the wise Mother Teresa said it best: “Everytime you smile at someone, it is an action of love, a gift to that person, a beautiful thing.”
