### Minimum Uncertainty

Is there a specific definition or meaning when a problem asks the minimum uncertainty of a position or speed of a particle? How would we apply that number to an experiment or in a written sentence, if that makes any sense.

Nope, just means to solve the problem normally. The uncertainty we usually calculate is a minimum value anyway - it can be higher.

### Re: Minimum Uncertainty

The Heisenberg equation is expressed as $\Delta p\Delta x\geq \frac{h}{4\pi}$, meaning that the uncertainty is greater than or equal to that value. Thus, the "minimum uncertainty" would be when the uncertainty is equal to h/(4$\pi$). So just change >/= to =.
