It was an overcast day, dominated by layers of clouds but every-once-in-a-while, the sun would peep thru. I had connected a low watt solar pump in a small pond and as the sun appeared it would turn on the water pump. It happened a few times. At first, I was an observer frozen in awe, but then I came to, and I recorded it. I realized that I was witnessing a relay of waves, from one form to another. I thought wow, the light did that!
As the sun came through the clouds, the light waves from the sun hit the solar panel, the water pump was activated (electric waves), and as the water fell in the pond, water waves were created, along with light waves, air waves and sound waves. All this was being recorded by my brain waves. It was awesome. Nature is great.
