    "abstract": "Chirality is not just a structural artifact in biology but it may provide for\na genuine biological advantage. This is due to the phenomenon of chiral\ninteraction (CI) which is described here for mechanical-chiral devices. The\nmain mechanical feature of chiral interaction is its mode of selecting one\ndirection of rotation out of two possible and opposite ones. For example, a\ngiven chiral device such as a rotating water sprinkler, rotates in one\ndirection. What does rotate in the opposite direction is the mirror of this\ngiven sprinkler. This mode of operation indicates space-time (PT) invariance\nwhich causes it to be also time-irreversible. This also causes a chiral device\nto become non-ergodic on microscopic level. This prevents certain chiral\nsystems from readily reaching thermal equilibrium, and causes the system to act\nnon-ergodically, which is crucial for living systems as well as for molecular\nevolution.",
