The introduction to the fundamental theories of our century's Physics - Relativity and Quantum Mechanics - is the subject of this widely known and used book "Modern Physics".

The level of mathematical treatment of the material (clearly higher than what is usually found in General Physics books), the clarity of presentation, and the abundance of examples are some of the advantages of the book, which explain its success among both Physics students and those from Polytechnic Schools.

The book is also considered particularly successful in applying the fundamental laws of Quantum Mechanics and Relativity to understand basic characteristics of matter at all levels of its organization: elementary particles, nuclei, atoms, molecules, solids.

The new technologies that have arisen from this understanding - lasers, semiconductor devices, superconductors, etc. - form the third main axis on which the book is developed and completed.

The edition is two-color with approximately three hundred and fifty illustrations, tables, and images.
