This book specially covers the application of mathematical physics and all its related aspects, including statistics. Modern physics recognizes four fundamental forces in nature: Gravitation, electromagnetic force, weak nuclear force and strong nuclear force. It has many branches, like, particle physics, geophysics, biophysics, astrophysics and nuclear physics. Present multi-volume work is important for many a factor. It covers various concerned issues at length and provides lots of insight into the subject. An excellent read for the physics enthusiasts.
