Scientific computing (Computational science)

1. Scientific computing, also known as computational science, is the interdisciplinary field of study that involves constructing mathematical models and quantitative analysis techniques to solve complex problems in various scientific disciplines. It utilizes advanced computing techniques and algorithms to simulate, analyze, and visualize complex systems and phenomena. Scientific computing is widely used in areas such as physics, chemistry, biology, engineering, and economics to gain deeper insights, make predictions, and optimize systems. By leveraging high-performance computing resources, scientific computing enables researchers and scientists to tackle large-scale problems that were previously impossible to solve using traditional methods. Overall, scientific computing plays a crucial role in advancing scientific knowledge, driving innovation, and solving real-world challenges.
