As a result of this indeterminacy of position (the precise principle is the position-momentum indeterminacy principle), particles exhibit diffraction patterns under circumstances that make evident the superposition (for instance, a barrier of appropriate dimensions with two openings that allow the passage of a particle will do).
According to the classification of Neutrosophy, "certainty-uncertainty principles" can be divided into three principles in different conditions: "certainty principle", namely a particle's position and momentum can be known simultaneously; "uncertainty principle", namely a particle's position and momentum cannot be known simultaneously; and neutral (fuzzy) "indeterminacy principle", namely whether or not a particle's position and momentum can be known simultaneously is undetermined.
The Heisenberg indeterminacy principle reads, for the entire fluctuation at a given t:
