Molekulyar xaos - Molecular chaos - In kinetic theory in physics,
molecular chaos is the assumption that the velocities of colliding particles are
uncorrelated, and independent of position. This assumption, also called in the
writings of Boltzmann the Stosszahlansatz, makes many calculations
tractable.

Elektr toki - Electric current -An electric current is a flow of electric
charge. Electric charge flows when there is voltage present across a
conductor. In electric circuits this charge is often carried by moving electrons
in a wire. It can also be carried by ions in an electrolyte, or by both ions and
electrons such as in plasma. The SI unit for measuring an electric current is
the ampere, which is the flow of electric charges through a surface at the rate
of one coulomb per second. Electric current can be measured using an
ammeter. Electric currents cause many effects, notably heating, but also
induce magnetic fields, which are widely used for motors, inductors and
generators.
