Abstract:

"Important Research Directions Changing Information Scientific Technology"

In the past several decades, the development of information technology mainly focused on high efficiency and large-scale production, with less focus on low energy consumption, low cost, usability, reliability, safety and individuation. In the first half of 21st century, the main stream of information technology development is popularization, application and benefit to the public. The popularization of information technology may take longer time and need technical innovations of higher levels than those of electricity technology. Current information industry is a high energy consumption industry, and there is still large space for low energy consumption information technology to develop.

This report points out that in the first half of 21st century, a new information science reform with characteristics of high-efficiency calculation and digital simulation will arise. Breakthroughs of scientific discovery may lead to a new technical reform in the last half of 21st century. A popular view at present that “computer simulation is the third way of scientific research other than experiment and theory research” is not quite proper. The trend of cross science development in 21st century is to put calculation into whole stages of scientific research, which will form a new form of scientific research. Within several decades in the future, simulative calculation may be an important research direction of computer scientists.
