Historical retrospects and evolutionary characteristics of paleogenomic science and technology

Paleogenomics is a discipline in which the extraction and analysis of DNA from ancient biological remains are studied to understand the evolutionary history of past organisms.Research on this topic has revealed the evolutionary history of humans and other species,traced human migrations and genetic changes,and investigated ancient diseases and environmental influences due to its uniqueness.This paper reviews the scientific and technological history of the development of paleogenomics,including the molecular cloning era,the polymerase chain reaction(PCR)technique era,the genomics era,and the bio-data analysis era.This field explores the key technological development processes and effects of significant scientific discoveries,ranging from gene cloning technology and sequencing technology to breakthroughs and applications in big data analysis,addressing challenges such as sample contamination and trace collection analysis in paleogenomics research.

On the Compilation Modes of Local History of Science and Technology——A Case Study of the History of Ba-Shu Science and Technology

The contents of"Ba-Shu History of Science and Technology"take up a single volume of A General History of Ba-Shu Culture.This paper attempts to explore compilation modes of the history of local science and technology by analyzing the compilation of"Shu History of Science and Technology".There are three approaches available,i.e.a general history-based approach,a discipline-based approach and an integrated approach,also known as a discipline-specific approach based on general history.This paper considers the integrated approach to be the most feasible as it elaborates Ba-Shu culture as a sub-culture of Chinese culture,the connotations of Ba-Shu achievements in science and technology,the special significance of the history of Ba-Shu science and technology,as well as the latest progress in studying the history of Ba-Shu science and technology.This paper also puts forward a possible choice to better approach the compilation of the history of local science and technology,reveals areas worth improving,and indicates a proper direction to move towards.

Ceramic Art Reality in the Context of Technology History

The art of ceramics originates from the basic activities of human beings,and uses the tools,following the methods,and the visual production activities combined with aesthetics.Modern technology has spawned new ceramic decoration methods and provided new ideas for artistic creation.Ceramic art relies on ceramic crafts.As the most technical form of many art categories,it is the representative of the“Combination of Art and Crafts”of arts and crafts,and it is the perfect embodiment of“Beauty”in the space-time carrier.The history of Chinese ceramic glaze shows that the study of the history of ceramic technology should rely on the aesthetics of ceramics,and the problems related to the interpretation of modern ceramic art cannot be separated from the context of the history of ceramic technology.

Creating technical heritage object replicas in a virtual environment

The paper presents innovative informatics methods for creating virtual technical heritage replicas, which are of significant scientific and practical importance not only to researchers but to the public in general. By performing 3D modeling and animation of aircrafts, spaceships, architectural-engineering buildings, and other technical objects, the process of teaming is achieved while promoting the preservation of the replicas for future generations. Modem approaches based on the wide usage of computer technologies attract a greater number of young people to explore the history of science and technology and renew their interest in the field of mechanical engineering.
