Computer simulation of physical processes is a universal in science and engineering as salt and pepper. In 1650 BC, Numerical algorithms were defined by the Ancient Egyptians as root- finding methods for solving equations.[1] Later, Greek mathematicians calculated the areas and volumes of geometric objects using numerical integration, which is being used today. After applying numerical methods to solve the mystery of gravity, many scientists switched to numerical analysis to address problems with solid and fluid mechanics. In the nineteenth century, magnetic fields and electrical fields were solved using numerical tech niques. These techniques were expanded upon in the 20th century to include quantum mechanics and relativity
