Mind-boggling reality

As if the idea of a device that makes an object seem invisible was not mind-boggling enough, researchers have now demonstrated a system that can conceal an event in time. See Letter p.62

Quantum physics is a world of its own, inhabited by strong personalities and mythical creatures such as Schrödinger’s cat, but also by mind-boggling experiments and theoretical rules that challenge our intuition while giving spectacular agreement with experimental results. How can we invite students into this fascinating world.

In this paper we show that interaction-free measurements, which have been object of much discussion in the last few decades, can be explained in a natural and intuitive way in the framework of complex nonlinear quantum physics, contrary to what is claimed by some orthodox authors that present them as incomprehensible, mind-boggling experiments.
