  • Computational Science : doing Science by means of computation ("in silico").
      Involves: scientific problem → math problem → computational algorithm → numerical solution → implications for original scientific problem.
      It has become the 3rd pillar of Science, complementing Theory and Experiment.
  • Real scientific/technological/managerial problems canNOT be solved explicitly/exactly.
      Need to be solved numerically (approximately), so need effective approximations/algorithms and understant the effects of errors in the calculations.
  • Want algorithms to be: effective, accurate, reliable, efficient and robust !
      These aims often play against each other, so trade-offs need to be made...
  • Issues of verification, validation, uncertainty quantification are becoming increasingly important.

    The course will simulate the core aspects of Computational Science including: modeling and computational simulation of physical phenomena,
    writing reports, writing proposals, collaborating with colleagues on a research project, and presenting your work.
