The ability to predict macroscopic physical and chemical properties from information derived at the micro-scale or atomic scale for various kinds of materials has yet to be perfected in the field of materials physics and chemistry. Although macro-scopic properties are determined by the micro or atomic structure of materials, it is still difficult to obtain such properties as hardness, intensity, surface tension, density, thermal expansion, thermal diffusion, viscosity and specific heat from a cell with just several atoms because of multi-scale effects.
