Heisenberg's Uncertainty Principle tries to explain the potential duality of an electron behaving as either a particle or wave.
Heisenberg's Uncertainty Principle illustrates that an electron can behave as a particle or as a wave, but never both simultaneously.
Concept #1: The duality of an electron.
Concept #2: To illustrate this dual nature of an electron Heisenberg created his Uncertainty or Indeterminacy Principle
Example #1: An electron has an uncertainty in its position of 630 pm. What is the uncertainty in its velocity?
