Hi, my name is Nathan Kutz and I'm a professor and chair of applied mathematics at the University of Washington. I'm here to tell you a little bit about scientific computing, and the course that you are looking at right now. This course was developed over a decade ago at the University of Washington, to address the needs, of the students in the engineering, physical and biological sciences. In particular, today, it's very difficult to do any kind of scientific work without having computational fluency. The course tries to highlight the major themes and techniques used mathematically from such diverse fields as biology to physics. It is a first of three courses offered by Corsera from applied mathematics. This course being scientific computing, the second being data analysis, and the third course being high performance computing. Combined together, they offer a wonderful survey of the methods and techniques in scientific computing. What's needed for this course is a strong background in linear algebra, differential equations and some background in algorithim and programing development. With those skill sets and a lot of work, you can wi, work your way through and cover the major themes and techniques mathematically that allow you to solve some of the world's most complex problems. In fact, the challenges posed by today's modern computation. Such as solving for how neurons interact in the brain for doing computations and functionality or for solving for very complex systems such as predicting weather or climate changes; are the kind of things we're after in doing scientific computing. I hope you'll join me in this course. I think you will find it to be a wonderful experience, and that you will learn a great meaning of mathematical techniques and cutting edge methods that you can use and apply across a great range of science.
