Description
We're surrounded by all kinds of matter, light, waves, motion, electricity, and so on. [Screams]. Why do you think there's a echo? It's a scientific principle that hides within the material through the concepts and principles of matter, and the kinds of play-players and tools and machines that we have around our lives.
