### Uncertainty

Are Uncertainty and Indeterminacy the same thing in this equation?

### Re: Uncertainty

This video does a pretty good job at explaining the concepts behind the Heisenberg Uncertainty Principle, and it also provides examples using the uncertainty equation (including an example that translates $\Delta p$ from the uncertainty equation to $m\Delta v$)

### Re: Uncertainty

Yes, uncertainty and indeterminacy are used interchangeably in this equation. The reason he often says "indeterminacy" instead of "uncertainty" is because uncertainty makes it sound like we are unsure of whether or not the equation is accurate even though it is. Indeterminacy is a better word because it instead connotes the fact that we know the object is there and that the equation is accurate but are simply unsure/indeterminate of its exact momentum and/or position.
