E. Schrödinger proposed a thought experiment to illustrate the discontinuity, not fully understood, that appears in quantum mechanics when a measurement process occurs. The cats in his thought experiment appear to be both alive and dead. This unreasonable appearance has not been satisfactorily explained before. Calibration, which is required in metrology, is not treated in physics theory. This paper illustrates how calibration to a non-local time standard explains the alive and dead appearance of Schrödinger's cats.
E. Schrödinger proposed a thought experiment to illustrate the discontinuity, not currently explained, that appears in quantum mechanics when a measurement occurs. Schrödinger's cats in his thought experiment appear to be both alive and dead. This unreasonable appearance has not been satisfactorily explained before. Calibration, which is required in metrology, is not included in physics theory. Schrödinger's thought experiment is explained by including calibration in measurement theory.
