System dynamics Dynamic stock and flow diagram of model New product adoption (model from article by John Sterman 2001) System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system.[1] What makes using system dynamics different from other approaches to studying complex systems is the use of feedback loops and stocks and flows. These elements help describe how even seemingly simple systems display baffling nonlinearity. System dynamics

玻色-愛因斯坦凝聚与量子計算机 玻色-愛因斯坦凝聚与量子計算机 【大紀元1月11日訊】德國科學家在新一期《自然》雜志上發表論文介紹說,通過改變激光束构築的三維能量點陣中激光的能量,他們首次實現了玻色-愛因斯坦凝聚態下銣原子气体的超流体態与絕緣態的可逆轉換。 据新華社報道,科學家認為這一發現具有重大意義,并可能為量子計算机的研究帶來重大突破。 在微觀狀態下讓物質處于可控制狀態一直是對科學家們的一個重大挑戰。1924年,印度物理學家玻色曾對光粒子進行了這方面的理論研究,并把重要的研究結果告訴了愛因斯坦。

From SystemsWiki Idealized Design, a segment of Interactive Planning, is an organizational development process developed by Russell L. Ackoff in the 1950's which enables an organization to get beyond the problem solving mode and unleash their innovative potential. Method “An idealized design of a system is the design its stakeholders would have right now if they could have any system they wanted. The design is subject to only two constraints: it must be technologically feasible (no science fiction), and it must be operationally viable (capable of surviving in the current environment if it came into existence, with or without modification).

The research of complex networks and systems The analysis of networks has received a major boost caused by the widespread availability of huge network data resources in the last years. One of the most surprising findings, popularized by Albert-László Barabási and his team, is that real networks behave very distinct from traditional assumptions of network theory.
