Subject Scope: Condensed Matter. This book presents a review of an original Hierarchic theory of condensed matter, general for liquids and solids and its numerous applications. Computer programs based on a new theory were used for comprehensive simulations of water and ice physical properties and validation of the theory. Condensed matter is considered as a system of 3D standing waves (collective excitations) of different nature: thermal de Broglie waves, IR photons and thermal phonons. Quantitative interrelation between microscopic, mesoscopic (as intermediate) and macroscopic properties of condensed matter were found. New theories of total internal energy, including contributions of kinetic and potential energies, heat capacity, surface tension, vapour pressure, thermal conductivity, viscosity and self-diffusion are described.
