wave-particle duality is like watching a television screen

Categories: Comparisons

An example of a teaching analogy:

"Sometimes electrons are described as being small particles of matter. At other times when we describe the organisation and behavior of electrons, we treat them as wave patterns.

Someone who had never seen a television would report seeing recognizable images of people, buildings, etc. when watching the screen from across the room. However, a similar observer, if placed with their eye right up against the screen, would report seeing dots of varying colors and brightness. Both descriptions of the screen are correct; the perspective of the viewer determines which properties are observed at that moment."
