- Can you really not measure the position and momentum of a particle simultaneously or is it just that there is uncertainty in what you will get?
Main Question or Discussion Point
The uncertainty principle tells us that there is no state that a particle can be in such that we can predict with certainty both what the result of a position measurement will be and what the result of a momentum measurement will be. This statement is not the same as saying we can't measure the position and momentum of a particle at the same time. The latter statement is often repeated. Is it correct?
