Observers Disturb What They Measure

시즌 1, 에피소드 3: Consider what life would be like if quantum effects held at our everyday scale. For instance, there would be no trouble sitting in three chairs at once! Learn what happens when a particle in such a mixed state is forced by measurement to assume a definite position: a situation known as wave function collapse. This leads to the important quantum principle that observers disturb what they measure.
