The Earth Impact Database is a collection of images, publications and abstracts that provides information about confirmed impact structures for the scientific community. It is hosted at the Planetary and Space Science Centre (PASSC) of the University of New Brunswick.
This small Python project is a physical simulation of two-dimensional physics. The animation is carried out using Matplotlib's
FuncAnimation method and is implemented by the class
Simulation. Each "particle" of the simulation is represented by an instance of the
Particle class and depicted as a circle with a fixed radius which undergoes elastic collisions with other particles.
The following code attempts to pack a predefined number of smaller circles (of random radii between two given limits) into a larger one.
The following code simulates (very approximately) the growth of a polycrystal from a number of seeds. Atoms are added to the crystal lattice of each of the resulting grains until no more will fit, creating realistic-looking boundaries where two grains meet.
