Physics tools
Particle Physics
CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences.
PAW is an interactive program providing interactive graphical presentation and statistical and mathematical analysis tools. It is designed to work on objects familiar to physicists such as histograms, event files (Ntuples), vectors, etc.
geant321 Particle detector description and simulation tool.
Geant version 4 Monte Carlo detector simulation libraries (RFP: 325305) - now has a real license but it is probably not DFSG-free. See also More about Geant 4
CLHEP HEP foundation class library.
Feynmf set of LaTeX macros for creating Feynman diagrams
Fluid Dynamics
gerris Gerris is a system for the solution of the partial differential equations describing fluid flow.
gpiv gpivtools A collection of programs for images that are generated during a Particle Image Velocimetry (PIV) experiment. This is a technique to obtain the velocity field of a fluid flow quantitatively and is performed by tracking tracer particles that have been seeded to a fluid.

Supporting Packages
Peak Fitting
fityk Fityk is a flexible and portable program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). In other words, for nonlinear peak separation and analysis.
Data Acquisition
See DebianScience/DataAcquisition and https://blends.debian.org/science/tasks/dataacquisition
Numerical Computation (MATLAB/IDL like)
https://blends.debian.org/science/tasks/numericalcomputation lists Matlab/IDL like packages for calculations on arrays, data analysis and visualisation.
Computer Algebra Systems
See DebianScience/ComputerAlgebraSystems for a comparison of some of these.
maxima Maxima is a fully symbolic computation program.
SymPy ?SymPy is a Python library for symbolic mathematics (manipulation).
sagemath Mathematics software written in Python
yacas Yacas is a small and highly flexible computer algebra language.The syntax is very close to Mathematica. The distribution contains a small library of mathematical functions, but its real strength is in the language in which you can easily write your own symbolic manipulation algorithms. It supports arbitrary precision arithmetic.
Image Analysis
See https://blends.debian.org/science/tasks/imageanalysis for applications to extract quantitative data from images.
