Subtopic: what is a system? up

Quote: humans have an inborn talent for guessing the system behind connected phenomena; we immediately build expectations of what is to come [steiM_1998]
Quote: the language of an algebra has its alphabet, vocabulary of signs, and a grammar that unites letters and signs into a system; letter symbols for fundamental conceptions; sign symbols for relations and combinations [peirB_1881 OK]
Quote: a system is a fixed arrangement of parts; parts become a system by instantiating some set of specific relations between them [fetzJH_1988]
Quote: a system is division of a whole into components with properties and actions; it is descriptive but not inherent [nygaK10_1986]
Quote: a system is a part of the world which someone chooses to see as made of components with properties and actions [nygaK_1981]
Quote: a system is those aspects of an organization that can be described and analyzed by formal means [holtAW3_1979]
Quote: a system consists of repeatable events and mutual constraints; an occurrence is one repetition of an event [holtAW9_1968]
Quote: artifacts are regular and repetitive; reflect the purpose of their creator [monoJ_1971]
Quote: a system is anything that interacts with its environment in a discrete fashion across a well-defined boundary [lampL1_1989]
Quote: discrete state machines move from state to state; don't really exist but still a useful abstraction [turiAM10_1950]

Subtopic: communication up

Quote: classification view of systems depends on a global perspective; communication view is localized and observable, like Plato's cave dwellers [wegnP10_1986]
Quote: an environment and system communicate by changing values of state functions, e.g., voltages on wires [lampL1_1989]

Subtopic: system as schema or system up

Quote: the word 'theory' use to mean 'speculation or contemplation'; now it means 'a scheme or system of ideas or statements held as an explanation or account of a group of facts or phenomena' [hackI_1975a]
Quote: the nature of knowledge has changed; now, a theory is a system of statements; before, knowledge was the cause of things derived from acquaintance with essences; a demonstration was a showing to the inward eye [hackI_1975a]
Quote: a system requires a schema, i.e., an a priori content and arrangement of parts; otherwise the unity is accidental [kantI_1781 OK]
Quote: information is the values within the outcome of a process; a variable has multiple values, without changing the type of system [loseRM3_1997]

Subtopic: foundation of a system up

Note: build a system by keyword, hierarchy, naming, or natural language; e.g., Roman vs. decimal numerals [cbb_1990 OK]

Subtopic: compexity up

Quote: in a digital device, changing a single bit can have drastic consequences; a radical novelty of computers [dijkEW12_1989]
Quote: man's creations can be more complex than the laws of nature; e.g., can predict tides but not when a system will overload [dennPJ9_1980]

Subtopic: history up

Quote: the theory of evolution adds history to biological and chemical laws; trying an almost unlimited variety of structures of groups of molecules [heisW_1958]

Subtopic: system as emergent property up

Quote: system is an emergent property of language; opposite to normal view [cbb_1990 OK]
Quote: set-points and programs as cause of behavior are still the products of an intelligent act with foreknowledge of regularity [turvMT_1984]
Quote: set-points such as body temperature are the result of system performance instead of the cause [turvMT_1984]
Quote: the phoneme may be the consequence of perception instead of an intermediate form [dreyHL_1979]
Quote: no part of the world is inherently a system [nygaK_1981]
Quote: mind can not arise from mindless parts; either all matter is consciousness, or consciousness is distinct from matter [wallAR_1870 OK]

Subtopic: resource up

Quote: a system theory should assume that all resources are limited; including space-time [petrCA10_1979]
Quote: the absence of certain entities is a resource, e.g., the absence of printing on a piece of paper [petrCA10_1979]
Quote: tools and jobs seek each other. Use the best tools for a job, and given the tools, find the best jobs [zipfGK_1949]

Subtopic: systematic knowledge up

Quote: architectonic is the art of constructing a system or a systematic unity to our knowledge [kantI_1781 OK]
Quote: a system is the unity of various knowledge under one idea, i.e., an a priori form of the whole [kantI_1781 OK]

Subtopic: rules up

Quote: regular rules are easier to learn, use, describe, and implement [maclBJ_1987]
Note: there are two kinds of rules: formal rules and regularities; Turing machines and words in a natural language [cbb_1990 OK]

Subtopic: sets up

Quote: Dedekind refers to a set as a 'system' [dedeR_1888]
Quote: for aggregate success, members must be the same to the system (as observed) and different to the environment (for survival) [weinGM_1979]
Quote: inanimate aggregates are common, e.g., books and ideas; they survive the destruction of copies or adherents [weinGM_1979]

Subtopic: self-stabization up

Quote: a system is self-stabilizing when it is guaranteed to arrive and stay at good states from any initial state; i.e., closure and convergence [schnM3_1993]

Subtopic: misuse of systems up

Quote: the mechanism of scientific management is wrong if applied without the essence [taylRW_1911 OK]
Quote: you cannot run a business, or anything else involving people, on a theory [geneH_1984]
