Inhalt: Biographical note: Michael V. Sadovskii, Institute for Electrophysics, Russian Academy of Sciences, Russia.

Inhalt: Main description: This book discusses the main concepts of the Standard Model of elementary particles in a compact and straightforward way. The work illustrates the unity of modern theoretical physics by combining approaches and concepts of the quantum field theory and modern condensed matter theory. The inductive approach allows a deep understanding of ideas and methods used for solving problems in this field.
