This should be one of the greatest laws of Quantum  mechanics which states that ′it is impossible to know  the actual position and momentum of a particle in space  but we can only predict it.′′   so we say  Δx . Δp ≥ (h/(4π))  where Δx = position              Δp = momentum               h = plank′s constant
