scientific importance of RANGOLIS
I would like to talk about the scientific reason behind rangolis.The most original form of rangolis are still drawn by some of the most orthodox families in India especially in the rural places. Here are a few sample rangoli designs:
Notice that they are symmetric around both X & Y axis, mostly have rounded edges and appear to be combination of several simpler designs superimposed over each other.
Before we get into the details of the rangoli design, I would like you to recollect the concept of harmonics in sound waves studied during high school physics course. Recollect that sound is actually made up of several harmonics where in each harmonic corresponds to a certain frequency.
When the right harmonics are combined, we get pleasing sounds that soothes the mind and calms us. It becomes melodious music.
This is in the sound domain. i.e The harmonic vibration patterns manifests into pleasing sounds which can soothe the mind. Similarly, in the visual domain, we have corresponding harmonics for every frequency which when combined, leads to artistic patterns which are pleasing to see and have a placid effect.
The reason a rangoli is drawn at the entrance of a house is because of it’s calming effect on a visitor who is just about to enter into the house. It divulges into vibrations in the visitor’s mind, putting him at ease, making him comfortable and happy.
Hence, rangoli is not just an art but actually a science of vibration pattern which was discovered by Indians thousands of years ago and been made a part of the culture for spiritual & scientific purposes.
