Hello @greenrun
Oh was this the reason? Now I know. It's interesting to know how piqued science is. Always trying to find reasons to even what ordinary persons may think insignificant, and will end up revealing the applications of such phenomenon. This is an instance.
Been a good read.

It is just like Steve Jobs told us, we should stay curious. The more curious we are, the more things we can do and learn. Thank you.
