Uncertainty Principle When we were young to see was to believe, we knew that sand was white and water blue, and then we found that colours could change hue, and thought our younger selves a touch naive. Now we have learned that time and life deceive, that time relates, and life's reality is Heisenberg deduced uncertainty, no matter what our senses may perceive. And so, again, we find ourselves at sea watching the waves break on a narrow beach wondering if tomorrow there will be anything solid left within our reach and will we find it in us to be brave when we are called to ride the breaking wave.
