We present a logical tool that can well be used to contribute to a rational understanding of the functioning of theoretical genetics. The tool itself is a numerical Table, comparable to some tables of Triangulation or of other function values. It has been produced based on natural numbers in the range of 1 to 136. It can be easily constructed on the Reader's own PC.

"Space, earth, man, and computer" in Chinese words that is "Tian, Di, Ren, Ji". This paper discusses how has integrated remote sensing system (RSS), global positioning system (GPS), data collected system (DCS), geographical information system (GIS), expert information system (EIS), management information system (MIS), decision-making information system (DIS), and virtual reality system (VRS) into one network system for information society. It is an open, complex, and great system.

Mutually-inversistic discrete mathematics is constructed by the author, including mutually-inversistic logic, set theory, analytic geometry, calculus, abstract algebra, universal matrix, covering all branches of mathematics, including foundations of mathematics, geometry, analysis, algebra. Unlike conventional discrete mathematics, which put together the branches of mathematics needed by computer science, not interrelated to one another, the branches of mutually-inversistic discrete mathematics are interrelated to one another, and they have many applications in information sciences.

Making researches on information which is regarded as a state variable of system from the perspective of system science can promote the development of information science. In the framework of system science model, the analysis of relations among three system attributes which are information, matter (mass) and energy is to the benefit of understanding the connotation of information better. Furthermore, for the different range of researches of theoretical informatics and subject informatics, we hold that the priority should be given to the development of subject informatics to strengthen the research of information science at this stage. And based on the difference between natural information and language and word information, a trend of the research of theoretical informatics is proposed.

Compared to newspapers, periodicals, radio and television and other media, Internet is a new media. Internet communication has self-organizing and heter-organizing mechanism. Although the self-organization of network communication occurs and develops in different levels of network communication system, it has similar performance and operating rules. On the basic level, elements of Internet system have their own spontaneous movement mechanism. however, the whole Internet can form a number of ordered structure and function. Therefore, like the self-organization of other systems, self-organizing network communication mechanism has the characteristics of their own as a result of dynamic behaviors.

In systems science, self-replication refers to the system or subsystem in the absence of a specific external system produces offspring related to its own structural system, such as the propagation of organisms is a self-replication, self-replication, therefore also called self-reproduction. Self-replication system is an important form of system self-organization. There is chose relationship between self-replication and self-growth、self-adaption, slightly more complex self-growth or self-adaption should contain some kind self-replication. Phenomena of self-replication exist in the internet communication system widely. Both self-growing and self-adaption in the internet communication system contain self-replication of internet communication elements. In this sense, self-replication of internet communication is the basic style of self-organization of internet communication.

As an important part of human information communication system, internet communication has become progressively a system with large scale, complex constructions and perfect functions through the complicated interactions among many sub-systems and their elements. In this process, which is mainly promoted by internet users, the self–growth of internet communication system not only increases the amount of its sub-systems and their elements, it also strengthens its constructions and functions. At the same time, the self–growth of internet communication system indicates that the system is an evolving system with self-organizing property.

As the characteristic feature and mark in science in information age, information science plays a crucial role. However, what is information and what is information science? What are the principles governing the processes of information flow? Is there any new, and meaningful methodologies supporting the study? What is the significance of the study to human society? How to promote the study of information science in the world academic community? Some of my understandings to these questions will be presented in the paper.

The Verb-driven Chinese natural language understanding system realizes logic-driven semantic analysis. There are two types of Chinese sentences –把(ba)- sentence and 被(bei)- sentence. In this paper we use λ-transformation to analyze them. Yan Jiang and Haihua Pan put out formal semantics theory based on the concepts of type and category [3]. We program to realize semantic level analysis and expression, try to realize the idea to algorithm, and formalize natural language to logical expressions. According category theory to analyze semantics and transform the concept of category to the "field" in corpus. Finally we program to control the flow of analysis process and realize the logic-driven semantic analysis system.

This article is devoted to the study on the development of tools and machines, the important part of productivity. The author introduces the characteristics of the development process and analyzes the radical reason and the driving force for the development. Based on the effect of tools and machines on human social development, the author tries to illustrate it is the intelligence that drives the social progress and human society have entered the intelligence age and become intelligence society.
