Impacts of the Earth Simulator on Science and Technology ( ２ ) ＊ Qualitative － Paradigm shift
“The future is in our present life” ☆ Modern science has given us mathematical and observational tools to reveal the history and background of our nature, but not given us a reliable scientific tool to predict what will happen in our nature ★ The future is unbounded and contains an infinite possibility of evolution
Future is our new challenge!
“Computer Simulation is the viable scientific tool to challenge to the Future”
“The Earth Simulator has awaken us to realize this fact !! ”
The Earth Simulator enables us to make a revolution in manufacturing as well ! ★ Much reduction in time and cost is achieved in the development of high/costly new technologies and products, such as automobile, rocket engine, new CNT materials, etc.
Simulation brings the future into the scientific realm The future includes: Science, Industry Environment SUMMARY
