How to Think Like a Computer Scientist: Learning with Python
Python is a fun and extremely easy-to-use programming language that has steadily gained in popularity over the last few years. Developed over ten years ago by Guido van Rossum, Python's simple syntax and overall feel is largely derived from ABC, a teaching language that was developed in the 1980's. However, Python was also created to solve real problems and it borrows a wide variety of features from programming languages such as C++, Java, Modula-3, and Scheme. Because of this, one of Python's m

X-Ray Vision, Crystallography
This site features a tutorial designed to allow students to gain an appreciation of how X-ray crystallography works. Using X-ray diffraction patterns to determine the arrangement of atoms in a molecule requires sophisticated mathematics. This activity depends only on light from an overhead projector passing through a ball-and-stick molecular model placed on the stage of the projector, making it an ideal introduction to x-ray diffraction.
