We demonstrate how the paradigm of complex networks can be used to model some aspects of the process of second language acquisition. When learning a new language, knowledge of 3000-4000 of the most frequent words appears to be a significant threshold, necessary to transfer reading skills from L1 to L2(1). We show that this threshold corresponds to the transition from Zipf's law to a non-Zipfian regime in the rank-frequency plot of words of the English language. Using a large dictionary, we then construct a graph representing this dictionary, and study topological properties of subgraphs generated by the k most frequent words of the language. The clustering coefficient of these subgraphs reaches a minimum in the same place as the crossover point in the rank-frequency plot. We conjecture that the coincidence of all these thresholds may indicate a change in the language structure, which occurs when the vocabulary size reaches about 3000-4000 words.

This paper describes a modeling, simulation, and evaluation system for planetary simulation, including dynamic 3D-visualization, event capturing, and experiment management. Because of the amount of information to be given, particularly presentation of detailed pictures, a first paper [3] has been published to inform about main aspects of our simulation system and in this paper we are concerned with handling of and experimenting with this system. To keep this paper self-contained, some paragraphs are abridged repeated.
