Wood is a useful, durable but flexible, hard or soft (depending on its source and the way of processing) and and the only re-newable material widely used throughout human history. We are living with it. Let us enter wood through science and in particular physics. Wood grows and lives because of the existence of capillarity, according to the Hagen-Poiseuille‘s law. The acoustic performance of wood is based on the Newton‘s second and Hooke‘s laws. The interaction of wood and moisture is full of physics following laws, e. g. Fick‘s and Fourier‘s, Naviére-Sokes equation and so on. Without physics it is impossible to get an exact knowledge of the behavior of wood in the human surroundings, wood based construction, using the wood as fuel, making fire protection and so on. The study of wood is mainly based, of course, on numerous fundamental and applied scientific disciplines, but a kind of art and handcraat is in action there as well., Vladimír Bahýl, Tibor Mészáros., and Obsahuje seznam literatury
