This is my understanding towards wave particle duality: Matter is neither wave or particle.The matter position can only be determined when we observed the matter. When the matter is not observed, the matter can be in any position, and have a wave function. So, I make the following deduction: When an electron is not observed, it behaves like a wave. The electron will "replicate" itself into infinity amount of "abstract" electron. I call them abstract, because they will not interact. Thus, when the electron is observed, one of the "abstract" electron become "concrete" electron. Is the deduction true? Feel free to criticized, correct or advise.
