We describe computational science as an interdisciplinary approach to doing science on computers. Our purpose is to introduce computational science as a legitimate interest of computer scientists.We present a possible foundation for computational science. These foundations show that there is a need to consider computational aspects of science at the scientific level. We next present some obstacles to computer scientists' participation in computational science. We see a cultural bias in computer science that inhibits participation. Finally, we indicate areas of mutual interests between computational science and computer science.
