PC5215, ``Numerical Recipes with Applications'' Semester I, Aug-Nov 2024

INSTRUCTOR: Prof. Wang Jian-Sheng

CLASS SCHEDULE: Mon/Thu 10:00-12:00 at S12-04-03. Final exam Wednesday 4 Dec 2024 9:00am at S13-M-09. For more info, login to Canvas.

TEXTBOOKS: "Introducing Python", B. Lubanovic; ``Numerical Recipes in C (1992), the Art of Scientific Computing,'' W. H. Press, etc.

MODULE DESCRIPTION: Covers computational techniques for the solution of problems arising in physics, with an emphasis on molecular simulation and modelling. Topics will be from the text, "Numerical Recipes", Press et al, supplemented with example problems in materials and condensed matter physics. The textbook is in C, but this course will use Python for programming. This course insures that graduate students intend to do research in computational physics will have sufficient background in computational methods and programming experience. Assessment: 4 labs + assignments 40%, midterm 15%, final 45%.
