Perucca, Antonella The Chinese remainder clock. (English) Zbl 1443.97012 Coll. Math. J. 48, No. 2, 82-89 (2017). Summary: We present an analog clock with five hands that illustrates the Chinese remainder theorem and that can be understood also by nonmathematicians. Moreover, we interpret the Chinese remainder theorem in terms of rotations and prove it without equations.
