Computers and Science

Bismarck V. Costa - UFMG

Simulation using computers has increasingly become a very important

approach for solving several kinds of problems in sciences. Computer

simulation can translate aspects of physical problems into a discrete

mathematical form recreating experiments and solving problems impossible

to be treated using traditional tools. Rather than adopting the traditional

theoretical practice of constructing layers of assumptions and

approximations, this modern numerical approach attacks the original

problem in all its details without making too many assumptions.

Numerical simulation provides an alternative tool of scientific

investigation, instead of carrying out expensive, time consuming or even

dangerous experiments in laboratories or on site. The numerical tools are

often more useful than the traditional experimental methods in terms

of providing insightful and complete information that cannot be directly

observed or measured, or difficult to acquire via other means.!

Numerical simulation with computers plays a valuable role in providing a

validation for theories, offers insights to the experimental results and

assists in the interpretation or even the discovery of new phenomena. It

acts also as a bridge between the experimental models and the theoretical

predictions.

The importance of the computer simulation approach is recognized in the

development of high-performance processing petaflop computers. Currently,

some countries have done it, others are held in a test phase.

In this talk we intend to show the state of the art of the computer

simulation for some areas around the world...
