This video is about the Ozma problem of distinguishing the chirality (ie lefthandedness or righthandedness) of matter using weak interaction processes like beta decay (for example in uranium), or neutral kaon/kmeson decay. This is wrapped up in the phenomenon of CP violation, by which charge and parity are both violated by certain weak interaction processes this enables antimatter to be unambiguously distinguished from matter, and left handed chirality from right handed.
