Computational science is an interdisciplinary field that uses computer simulations and mathematical models to solve complex scientific problems. It combines elements from computer science, mathematics, and various scientific disciplines, such as physics, biology, and chemistry, to analyze and predict natural phenomena. Researchers in computational science develop algorithms and software to process large datasets and simulate real-world systems. This approach allows scientists to explore scenarios that may be difficult or impossible to test in a laboratory, leading to new insights and advancements in fields like climate modeling and drug discovery.
