Diffraction can be seen as transmission of light with no visible purpose. However, on close examination, it can very well be seen as the process by which, light makes itself visible. This reasoning can be extended to other all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.
I think diffraction is something connected to living beings too. It is an important part of us, our conduct when we are with no visible purpose. And it can act as a true indicator to our character.
I therefore think, there is a need to change the way we measure fellow humans. The present pattern, of tests, examinations, and trials should be replaced by something that can measure human diffraction, that is, the way we do, when we are with no purpose.
Imagine of a society that gives equal importance to all acts, however random those be. No pressure to perform, and no hurry to deliver?
I think, that, then is a society, where absolute calm can prevail.
