To decipher the atomic structures of materials, scientists often blast them with x-rays or neutrons and study the scattering patterns that result. Students of diffraction physics may find useful this “pictorial guide to crystal structures and their Fourier transforms,” or what scattering data look like after they've been processed by a computer. Aimed mainly at graduate students, the site includes eight interactive simulations that allow users to tweak an atomic structure and see its Fourier transform.
