What is computational science?
We all "know" what science is. We've taken courses on: biology, physics, chemistry, geology, etc. But what is science? It is the process by which we observe, infer general principles that systematize those observations, then deduce the observable consequences of those principles.
Computational science is a discipline that has grown as science has progressed. It includes the development and application of problem-solving methodologies that rely on advanced computational resources to solve complex problems in the sciences and engineering.
What is a research project in computational science?
A computational scientist (computational mathematician, computational physicist, etc.) deal with high performance computing (HPC) and high throughput computing (HTC) and many other topics most undergraduates don't hear about until they are ready to graduate.
You will be using HPC and/or HTC, and computational methods to solve a scientific problem in your discipline.
