I wish I was the last note of a piano piece which lingers for a few seconds before vanishing into the silence that surrounds it or the fingers of the pianist which stay in place for the same few seconds till it vanishes.

I found out why a bell is referred to as a ding-dong today. Earlier, church bells used to the only ones in high towers and they always swayed. When they rang, when the bell swung closer to you, you hear a ding. And when it moved away from you, due to the wonder that is the doppler effect, you hear the ding, as a dong.

How I love physics.
