The "Strange Loop" phenomenon occurs whenever, by moving upwards (or downwards) through levels of some hierarchial system, we unexpectedly find ourselves right back where we started.

Engineers speak of a “control loop,” in which the “man in the loop” is the problematical element. This is the human component in a series of sequentially interacting pieces of equipment that control or adjust a function. But when the pilot is suddenly and unexpectedly brought into the control loop (in other words, participates in decision making) as a result of (inevitable) equipment failure, he is disoriented. Long periods of passive monitoring make one unprepared to act in emergencies. The sudden appearance of several alarms, all there for safety reasons, leads to disorientation.

Active loose coupling occurs when a subsystem of an organization is more tightly coupled to an environmental sector than other subsystems, and a feedback loop connects environmental conditions with organizational responses. A feedback loop is present when an organizational mechanism for monitoring the environment exists, and when the state of the environment (or intended target of the organization's action) is compared to some desired state by members of the organization.

In short, there are surprising new structures that looping gives rise to that constitute a new level of reality that could in principle be deduced from the basic loop and its detailed properties, but that in practice have a different kind of “life of their own” and that demand — at least when it comes to extremely finite, simplicity-seeking, pattern-loving creatures like us — a new vocabulary and a new level of description that transcend the basic level out of which they emerge.

That a system is open means, not simply that it engages in interchanges with the environment, but that this interchange is an essential factor underlying the system's viability, its reproductive ability or continuity, and its ability to change.

If you don't pay appropriate attention to what has your attention, it will take more of your attention than it deserves.

Your attention will continue to be grabbed by anything until you give it the appropriate attention.

"the Godelian strange loop that arises in formal systems in mathematics (i.e., collections of rules for churning out an endless series of mathematical truths solely by mechanical symbol-shunting without any regard to meanings or ideas hidden in the shapes being manipulated) is a loop that allows such a system to "perceive itself", to talk about itself, to become "self-aware", and in a sense it would not be going too far to say that by virtue of having such a loop, a formal system acquires a self."

The term closed loop-learning process refers to the idea that one learns by determining what s desired and comparing what is actually taking place as measured at the process and feedback for comparison. The difference between what is desired and what is taking place provides an error indication which is used to develop a signal to the process being controlled.

This I know: the mind, left to itself, repeats the same stories, the same loops. Mostly ones that don't serve us. So what's practical, what's transformative, is to consciously choose a thought. Then practice it again and again. With emotion, with feeling, with acceptance. Lay down the synaptic pathways until the mind starts playing it automatically. Do this with enough intensity over time and the mind will have no choice. That's how it operates. Where do you think your original loops came from?

This automatic feedback is another reason extreme athletes have found flow so frequently, but what if we’re interested in pulling this trigger without help from the laws of physics? No mystery here. Tighten feedback loops. Put mechanisms in place so attention doesn’t have to wander. Ask for more input. How much input? Well, forget quarterly reviews. Think daily reviews. Studies have found that in professions with less direct feedback loops — stock analysis, psychiatry, and medicine — even the best get worse over time.

We find systems which by their very nature and definition are not closed systems. Every living organism is essentially an open system. It maintains itself in a continuous inflow and outflow, a building up and breaking down of components, never being, so long as it is alive, in a state of chemical and thermodynamic equilibrium but maintained in a so-called steady state which is distinct from the latter.

The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it.

Things hold your attention hostage until you give them the appropriate attention.
