👉 Firked is a mathematical concept in quantum mechanics, which refers to a system that cannot be fully described by linear combinations of its constituent parts. It's an analogical description of quantum systems where particles are thought to not interact with each other but rather with their environment through interactions with the surrounding matter. In classical physics, firked systems describe objects that are in contact with their surroundings at all times (i.e., they cannot be isolated), and these interactions lead to a non-linear behavior.
