Uncertainty principle
A quantum-mechanical bound on the product of standard deviations of conjugate observables such as position and momentum.
In one sentence
What does Uncertainty principle mean?
A quantum-mechanical bound on the product of standard deviations of conjugate observables such as position and momentum.
How it is written
ΔxΔp≥ℏ/2
A compact example
Reducing position uncertainty constrains momentum uncertainty from becoming arbitrarily small at the same time.
Other names and search terms
Heisenberg uncertainty principle.
