i was reading brian cox's book about *the quantum universe *(adsbygoogle = window.adsbygoogle || []).push({});

and he said something interesting

if for instance we know that a particle exists in ΔX , then this delta has to be less than one wavelength * he did it with clocks * to know the probability of its existence somewhere else in the universe , because if it was more than one wavelength , probabilities would cancel each other out at this point that i want to know the probability of the existence of the particle at

but i think it would make more sense if it was actually less than HALF a wavelength , because if my certainty in the position of the particle was less than half a wavelengths , then there is going to be no chance that probabilities will cancel out , right ?
