In modern science, when we talk of physics, it is useful to further subdivide the subject into various disciplines, including astrophysics, atomic physics, molecular physics, biophysics, solid state physics, optical and laser physics, fluid and plasma physics, nuclear physics and particle physics, etc. Progress in physics frequently comes about, when experimentalists make a discovery that existing theories cannot suffice further, necessitating the formulation of new theories. Likewise ideas, arising from one theory, often inspire new experiments. Research in physics is continually progressing on larger fronts.
Realising the need of a specialised book on ?College Physics? that covers all the aspects of the subject, we have made this effort. Hopefully, with this book the students and general readers would be benefited, equally.
