In the everyday world, we can perform measurements with nearly unlimited precision. But in the quantum world--the realm of atoms, electrons, photons, and other tiny particles--this becomes much harder. Every measurement made disturbs the object and results in measurement errors. In fact, everything from the instruments used to the system's properties might impact the outcome, which scientists call noise.
