FísicaLab is an educational application to solve physics problems. The problems are set up by adding elements from the palette to a chalkboard and entering the data for each element. The elements are objects such as blocks, pulleys, motors, and forces. It can use the SI and English unit systems, scientific notation, and many conversion factors. The types of problems that can be solved are kinematics of particles (including circular motion), static analysis of particles and rigid bodies in 2D, dynamic analysis of particles in 2D (excluding the dynamics of circular motion), heat, calorimetry, ideal gas, and expansion. The static and dynamic problems are entered by constructing the free body diagrams of the objects.
GATE is a software package dedicated to numerical simulations in medical imaging and radiotherapy. It supports simulations of Emission Tomography (Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT)), Computed Tomography (CT), and Radiotherapy experiments. It makes it easy to use existing Monte Carlo simulation packages according to the requirements of a simulation. It allows accurate description of time-dependent phenomena such as source or detector movement and source decay kinetics. It includes well-validated physics models, geometry modeling tools accommodating complex scanner geometries, models for detector electronic response, and efficient visualization utilities. Modelling of CT scans and calculation of dose can also be performed.
GaussianBeam is a Gaussian optics simulator. It features table-top display of the optical setup. It computes the beam parameters. You can move optics with the mouse. Available optics: lenses, flat and curved interfaces, mirrors, dielectric slab, and generic ABCD. Magic waist function: given a target waist, GaussianBeam finds the suitable arrangement of lenses. Fit waist function: measure the beam radius or diameter to define the input beam. The ability to save and load configurations.
Gravity animates HTML page elements using the laws of physics. It uses the Box2DWeb library to animate given page elements so they move, rotate, and collide. The gravity acceleration and direction are configurable. Given callback functions may be invoked when objects collide. Objects' speed and rotation may be affected when the user drags them using the mouse pointer. Each page element can be made static or animated. Animated page elements may include the respective children elements. The elements' friction and density properties can also be configured.
Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyzing SEM (scaning electron microscopy) data or any other 2D data.
