Interferometer - wave mode and particle mode

Quantum objects are neither particles nor waves, they possess both particle aspects and wave aspects.
In this video we explore quantitative measures for "particle-ness" (knowledge about the path taken through an interferometer) and "wave-ness" (visibility of the interference fringes) and establish the compromises that nature allows between them.
Spoiler alert: You can be pretty sure about the path and also observe well visible fringes.
