Continuum Mechanics/Basic Assumptions of Continuum Mechanics

Structure of matter

 * 1) Characteristic sizes of atoms and molecules (on example of hydrogen atom and molecule)
 * 2) Number of molecules in different volumes of different gases in different spaces
 * 3) Distribution of mass
 * 4) Molecules move chaotically

Interactions between particles
Something about how to reduce phenomena of durability and elasticity to Coulomb interactions.
 * 1) Gravitational (considerable among large objects, almost inconspicuous on molecule level)
 * 2) Weak
 * 3) Strong (considerable only on very short distances, large amount of energy is needed to get such distances)
 * 4) Electromagnetic - exactly what we need

Considerable physical and chemical processes

 * 1) Electrodynamics
 * 2) Phase states (examples)
 * 3) Properties of matter and components of compounds
 * 4) Chemical reactions
 * 5) Phase transitions
 * 6) Thermal motion
 * 7) Thermal expansion
 * 8) Viscosity
 * 9) Eradiation
 * 10) Polarization and magnetization
 * 11) Quantum mechanics

Statistical and Phenomenological Description of Substances
Usage of mean, summary or global characteristics is essential.
 * 1) Futility of trying to write a system of equations to every particle
 * 1) Disadvantages of statistical description due to need of additional sometimes groundless hypotheses
 * 2) Cute phenomenological description

About Space and Time

 * Metric manifolds
 * E.g. 3-dimensional Euclidean space
 * We will not use pseudo Euclidean spaces
 * Absolute time
 * Newton mechanics
