So, a friend and I were explaining some quantum things to another friend, Clayton, and I thought that you guys may me interested in this as well.
This is the double slit-experiment which shows that waves interfere with one another to form a banded pattern against a wall since at different points they either cancel out or cohere with one another.
This is used to demonstrate that particles of matter also have wave-like characteristics as well.
It turns out that even if you fire individual particles (usually electrons in experiments) on at a time at a wall, even though there aren’t any other particles to interfere with, you still get this pattern over time. The particles literally are interfering with themselves from different probability distributions. Pretty cool, huh?
Here is the electron graph:
