A mosquito of mass $0.15mg$

Speed of $0.15mg$

Uncertainty of$0.5mm/s$

Given the uncertainty in the velocity, we need to work out the limit on the position measurement ($\text{螖虫}$).

Mosquitoes have a very low positional uncertainty, which is a feature of particles in general. In other words, the mosquito's associated wave is so little that the classical treatment of its motion provides a very close approximation to its true motion. To begin addressing the mosquito's wave nature, its mass must be at least somewhat comparable to that of the electron. As a result, the conclusion is that the uncertainty principle does not obstruct the classical treatment in this circumstance.
