Starting from the binding energies of finite or isolated nuclei, to investigate ways to study inhomogeneous nuclear matter, i.e., nuclei with a free gas of neutrons, we review and discuss a general method to solve the nuclear equation of state for neutron stars by finding the solution for uniform nuclear matter. We also discuss a way to develop the nuclear equation of state in the presence of hyperons. The mass-radius relations of neutron stars are compared with the results of X-ray burst analyses to probe the validities of various models for the nuclear equation of state in neutron star physics.
