In nature there are many different minerals we call "Salts". If you look very closely at the particles of table salt, you will find little cubic crystals. These salt crystals are made of sodium chloride (NaCl), and their cubic shape is...

All matter is made of atoms! And atoms are made of even smaller more fundamental particles. Atoms are not shiny little rigid spheres as we depict in drawings and simulations; they're more like a squishy storm of tiny particles swirling...

These programs are classical 2-dimensional molecular dynamics simulations. Such simulations compute the motions of atoms by summing (integrating) all of the forces that the atoms exert on each other. These forces arise from changes in...
