一、The position o源自 scientific computing
1. In scientific research The third eye of the modern scientific research. The three methods of the modern scientific research:
Let us image the style of scientific research after “ASCI” plan is finished: (As an example, car’s or plane’s outer curve design)
An iterative process with three steps
is beautiful but the path is full of difficulties
二、The future of scientific computing
Sep. 1996, America DOE proposed “ASCI” plan（加速战略计算创新）
The object of ASCI: In computer platform with 1014 Flop/s （ 100万亿次/秒）, 3D complete physics processing, complete scalable, high precision scientific simulation computing will be done.
Theory Experiment Scientific computing
Importance of scientific computing:
Foreign university, since 1970. Chinese university, since 1990. Tongji University, since 1999.
What is it?
The course involves the two parts: 1. Algorithms:
ideas for obtaining numerical solutions to various mathematical problems; 2. The computer program: to communicate the algorithms to computer, FORTRAN(C), or Matlab.

Judgement: if the computed drag force > the required drag force, then repeat step (1),(2); else exit from the iteration loop, stop.
Climate Prediction
The three kernel problems in scientific computing:
suitable mathematical modeling high efficiency numerical method high performance computer platform

Design: using CAD software to design to outer curve of car or plane. The two preliminary factor: beautiful smaller drag force
Computing: using computational air dynamics, obtaining the drag force of car or plane.
