Emergence - Wikiparency

# Emergence Emergence is the appearance of novel properties or behaviors at higher levels that arise from interactions among lower-level components yet are not present in those components alone. Weak (reducible) and strong (irreducible) forms, [[Phase_transition|phase transitions]], swarm intelligence, and macro–micro relations illustrate the concept across physics, [[Biology|biology]], mind, and society.  ## Microsims (promoted from legacy — three.js first) ### MicroSim spec - **Recommended sim type:** [[Agent-based_model|agent-based model]] - **Microsimmability score:** 80/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Number of agents` - `Local rule` - `Density` ### What animates Simple agents following one rule produce a higher-level pattern none of them encodes. ### Learning objective Show how higher-level order emerges from simple parts following local rules. ### MicroSim spec - **Recommended sim type:** emergence / agent-based - **Microsimmability score:** 84/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Number of parts` - `Interaction strength` - `Noise` ### What animates Local interactions assemble a large-scale pattern that no single part contains. ### Learning objective Show how whole-[[System|system]] patterns emerge from simple parts.   ## Microsims — three.js ### Emergence (three.js) <div class="microsim-player"> <iframe src="https://wikitube-3d-microsims.netlify.app/Emergence.html" width="100%" height="620" frameborder="0" loading="lazy" sandbox="allow-scripts allow-same-origin" title="Emergence — three.js microsim"></iframe> </div> **Open it full-screen:** [Emergence.html](https://wikitube-3d-microsims.netlify.app/Emergence.html) · library `threejs` · route `microsim/threejs/` ### Related microsims Live sims on neighbouring articles — 6 of them inside this article's own Wikipedia link tree: - [[Agent-based_model]] *(in tree)* - [[Complex_system]] *(in tree)* - [[Feedback]] *(in tree)* - [[Network_theory]] *(in tree)* - [[Phase_space]] *(in tree)* - [[Self-organization]] *(in tree)* *Sim hosted off-article; the article owns the reference, not the runtime (WIKI_RULES §10.4).

[[Cybernetics|Cybernetics]] framed the question — [[Norbert_Wiener|Wiener]], [[W._Ross_Ashby|Ashby]], [[Gregory_Bateson|Bateson]] — and [[Systems_theory|systems theory]] under [[Ludwig_von_Bertalanffy|von Bertalanffy]] generalized it. Watching it happen is what the executable models are for: the [[Cellular_automaton|cellular automaton]], the [[Agent-based_model|agent-based model]], [[Population_dynamics|population dynamics]], and the [[Neural_network_(machine_learning)|neural networks]] of modern [[Artificial_intelligence|artificial intelligence]], whose macro-behaviors surprise their own designers. [[Systems_biology|Systems biology]] and [[Systems_science|systems science]] treat life and institutions as the standing proof, with [[Game_theory|game theory]] explaining how local strategy becomes global pattern. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Emergence) : [Wikitube](https://en.wikitube.io/wiki/Emergence) ## Previous hub tags Hubs: `Systems`.
