In 1977,[33] physicists E. C. G. Sudarshan and B. Misra studying quantum mechanics discovered that the dynamical evolution (motion) of a quantum system can be hindered (or even inhibited) through observation of the system.[34] This effect is usually called the "quantum Zeno effect" as it is strongly reminiscent of Zeno's arrow paradox.

This effect was first theorized in 1958.[35]
