In this essay I describe my personal journey from reductionist to systems cell biology and describe how this in turn led to a 3-year sea voyage to explore complex ocean communities. In describing this journey, I hope to convey some important principles that I gleaned along the way. I realized that cellular functions emerge from multiple molecular interactions and that new approaches borrowed from statistical physics are required to understand the emergence of such complex systems. Then I wondered how such interaction networks developed during evolution. Because life first evolved in the oceans, it became a natural thing to start looking at the small organisms that compose the plankton in the world's oceans, of which 98% are … individual cells—hence the Tara Oceans voyage, which finished on 31 March 2012 in Lorient, France, after a 60,000-mile around-the-world journey that collected more than 30,000 samples from 153 sampling stations.

Language is a mean of communication among people including speech, writing, and singing. Language is an important factor in geographical diversity. The English word language drives from the Indo-European. Language is the human ability to acquire and use complex systems of communication. The scientific study of language is called linguistic. Language is a strong element of culture. "Language is a systematic means of communicating ideas and feeling by the use of conventionalized sings, gestures, marks or especially articulate vocal sounds”. At present 5-6, thousands of languages are present in the world. Between them 1200, languages are present in Africa and 600 languages in India. Language provides the single most common variable by which cultural groups are identified. Language provides the main means by which learned customs and skills pass from one generation to the next. Facilitates cultural diffusion of innovations. Because languages vary spatially, they reinforce the sense of region and place. Study of language called linguistic geography and geolinguistics by geographers.

Superintelligent systems are likely to present serious safety issues, since such entities would have great power to control the future according to their possibly misaligned goals or motivation systems. Oracle AIs (OAI) are confined AIs that can only answer questions and do not act in the world, represent one particular solution to this problem. However even Oracles are not particularly safe: humans are still vulnerable to traps, social engineering, or simply becoming dependent on the OAI. But OAIs are still strictly safer than general AIs, and there are many extra layers of precautions we can add on top of these. This paper begins with the definition of the OAI Confinement Problem. After analysis of existing solutions and their shortcomings, a protocol is proposed aimed at making a more secure confinement environment which might delay negative effects from a potentially unfriendly superintelligence while allowing for future research and development of superintelligent systems.

Aspects from condensed matter physics combined with recent advances on statistical physics and physics of complex systems related to critical phenomena have inspired the continuous experimental study of electromagnetic precursory phenomena. For example, during the last two decades anomalous electromagnetic signals have been repeatedly observed before big earthquakes. Since it has been independently found that weak electromagnetic fields can produce biological effects, the following possibility is forwarded in this paper: The finding that electromagnetic signals are emitted before earthquakes, may be the key for the explanation that anomalous animal behavior have been frequently observed in various countries before major events.

Videogames have dominated popular culture for some time, but only in 2004 did they make a significant break into the world of politics, advocacy, and activism. This paper provides an overview of a variety of types of games used for political speech, from endorsed party messages to activist dissent. After explaining the state of the field, I discuss approaches to design and measure success for such artifacts. While some political opinion is black and white, most issues occupy grey areas, heavily influenced by other public policy issues. Can healthcare reform really be separated from taxation, national budgeting, tort reform, and social security reform? Far from neatly isolated problems, policy issues are complex systems that recombine and interrelate with one another. In particular, I will interrogate how videogames afford a new perspective on political issues, since they are especially effective at representing complex systems. Central to the process of creating and understanding such games is an understanding of “procedural rhetoric” — the way that a videogame embodies ideology in its computational structure. By understanding how games express rhetoric in their rules, we not only gain a critical vantage point on videogame artifacts, but also we can begin to consider how to design games whose primary purpose is to editorialize, teach, and make political statements.

In this article we explore the possibility of viewing complex systems, as well as the models we create of such systems, as operating within a particular type of economy. The type of economy we aim to establish here is inspired by Jacques Derrida’s reading of George Bataille’s notion of a general economy. We restrict our discussion to the philosophical use of the word ‘economy’. This reading tries to overcome the idea of an economy as restricted to a single logos or master narrative. At the same time, however, Derrida illustrates that we always operate from a restricted framework and as such something will always escape and interrupt our understanding of the world. In this paper we will propose that one could use Derrida’s reading of Bataille, along with notions such as différance, in order to move towards an understanding of complex systems as existing within certain sets of possibilities and constraints. We argue that this view of an economy agrees with the work of Edgar Morin on complexity and his conceptualization of general complexity.

Recently, simple dynamical systems such as the 1-d maps on the interval, gained significant attention in the context of statistical physics and complex systems. The decay of correlations in these systems, can be characterized and measured by correlation functions. In the context of symbolic dynamics of the nonchaotic multifractal attractors (i.e. Feigenbaum attractors), one observable, the symbol-to-symbol correlation function, for the generating partition of the logistic map, is rigorously introduced and checked by numerical experiments. Thanks to the Metropolis–Stein–Stein (MSS) algorithm, this observable can be calculated analytically, giving predictions in absolute accordance with numerical computations. The deep, algorithmic structure of the observable is revealed clearly reflecting the complexity of the multifractal attractor.

The dynamics of complex systems far from their equilibrium state are currently not fully understood. Besides the theoretical interest for better understanding the world around us this limitation has important practical implications to our ability to model, understand and therefore manage and control complex systems. In a first step to better understand the non- equilibrium dynamics and improve our ability to model complex systems I implement a cellular automaton model of gas mixing. I simulate the evolution towards equilibrium starting from a state of macroscopic order and as the system evolves I calculate the Kolmogorov complexity, the information entropy and the box-counting dimension of the system. I observe a transient peak in complexity, entropy and fractality of the system. To test the genericity of this pattern I implement a very different model, the game of life, where I find the same statistical patterns.

Abstract The main motivation for this paper is that a negligible number of reforms in education systems, initiated all over the world, proved to be successful in terms of bringing desired results in promoting educational practice and its final goal - the promotion of students’ learning and knowledge. Regarding the education system and its reform a change of paradigm has recently happened. In some cases, changes were made gradually, whereas in other cases it was completely abandonment of treating them as complicated systems with simple interventions and solutions toward the recognition and respect of their true complex nature. So, this reviewed paper explores new insights and tools derived from the theory of complexity. They can help to better understand and navigate the education system and its reform. Becoming familiarised with methodological implications of viewing the education system and its reform as complex system is recommendation for different stakeholders included in education system, such as teachers, students, researchers, administrators and policy makers. Advance awareness of both urgency and opportunities of analysing and respecting the education system as a complex system would contribute to better understanding the essence of dynamic wholeness of education and, for sure, would provide desired results of educational reform. For all of us that means more successful coping with the world characterised by a growing number of complex systems with growing intensity.
