The collective motion of birds is studied numerically. The effect of the anisotropy mutual interaction parameter plays a vital role on the order parameter of the collective motion of biological groups like birds, fishes etc. It is found that, if the interaction with the elements in front of a given element is stronger than with those behind, then the system will move as a single unit.Keywords

The classical three body problem of helium atom is studied numerically in two dimensions. The orbits and phase space of the electrons for different initial conditions are investigated by solving the equations of motion numerically. The phase space shows interesting result of band structure similar to the quantum mechanical result of the solids. The variation of auto-ionization with perturbation parameter is also established.Keywords
