smib is one of the smallest and simplest computer algebra system in the world, but simple does not mean simplistic. Using smib you can explore many branches of mathematics (e.g. number theory, algebra, calculus, numerical analysis, differential geometry, probability and stochastic calculus) and also some physics (e.g. electromagnetism and quantum mechanics).. By simple you can understand easy to program (smib is a dynamically typed language, with strong affinity to recursivity, programs are often short and powerful and maybe useful for teaching), and also easy to modify (source code is free, written in C language, and based on notions of stacks and lists). ...

PyVCI
Vibrational configuration interaction code for simulating IR spectra
The PyVCI program package is a general purpose open-source code for simulating accurate molecular spectra, based upon force field expansions of the potential energy surface in normal mode coordinates. It includes harmonic normal coordinate analysis and vibrational configuration interaction (VCI) algorithms, implemented primarily in Python for accessibility but with time-consuming routines written in C. Coriolis coupling terms may be optionally included in the vibrational Hamiltonian. Quartic force fields are obtained from the PyPES library of high quality analytical potential energy surfaces (http://sourceforge.net/projects/pypes-lib) or by numerical differentiation of analytic second derivatives generated using the GAMESS quantum chemical program package (http://www.msg.ameslab.gov/gamess/). -

Particle Correlation Analysis
Simulation program
This program develops a model of the volume of the particles in the optically transparent medium. The volume is represented as a set of layers with equal distances maintained between them. Whereby these layers contain particles. The wavefront passing through the predetermined volume is thus scattered by the particles in each layer. Axial hologram is reconstructed by numerical back propagation of the wavefront to the first layer of volume. Further, two adjacent layers with particles are... -
