"In fact any experiment that measures a quantum effect is one in which the quantum effect is aligned with the behavior of some heavy, macroscopic object; that's how we measure it"

This quote by Murray Gell-Mann is describing the truth that quantum impacts can just be determined by observing the habits of a big, macroscopic object. This is due to the fact that quantum effects are so small and subtle that they can not be determined directly. Instead, they should be observed indirectly by taking a look at the behavior of a large object that is affected by the quantum effect. This is why any experiment that determines a quantum result should involve the alignment of the quantum effect with the behavior of a big, macroscopic item. This is the only method to measure the quantum result and get an understanding of its residential or commercial properties.
