Classical mechanics describe systems in classical particles, it explains The Newtonian equation, Hamiltonian equation and Lagrangian equations, Rutherford scattering, theory of small oscillations, coupled oscillations wave characteristics and it's behavior. This includes the speed of particles should be speed of light. But in quantum mechanics the seed of light must be greater than the speed of electromagnetic radiation.

This book is intended to introduce students to the basic ideas that underlie Fundamental Condensed matter PHYSICS, with emphasis on the behavior of electron in crystalline structurs, particularly in materials that are metallic. This will enable the students to learn the subject matter in order to explain and account for the physical, thermal, electrical and optical properties of a solids. Students will appreciate Condensed matter physics as one branch of physics which plays a fundamental role in the electronic industry.
