Vini, while doing the resonance column experiment, notices that when the conditions became suitable for ‘resonance’, the loudness of sound became maximum and it remained sustained for long. On coming back home, she narrated her observations to her grandfather. Though he was unable to understand the physics of the phenomenon, he realised that similar things happen in real life too. He told Vini that when we align, and orient, out thinking and actions, in a adaptive and accommodating way, our life becomes more vibrant, happy and productive. We are then in resonance with the environment and the society.
