What is Computational Science?
Computational science is the application of computer science and software engineering principles to solve scientific problems. It involves the use of computer hardware, networks, algorithms, programming, databases, and other domain-specific knowledge to design simulations of physical phenomena that run on computers. Computational Science transcends disciplines and can even include the humanities.
While scientists have used computers in their research since they were invented, the increasing power of new hardware in recent years has made it possible to create simulations of complexities previously unthinkable, such as particle physics. Computational Science is the use of knowledge about hardware, algorithms and other scientific findings to simulate the physical world on powerful supercomputers.
Computational Science is multidisciplinary and involves scientists from the natural sciences, computer scientists, software engineers and even people from the humanities. Techniques usually involve numerical simulations.
