  An instantaneous temperature path of a point particle in the space -
temperature manifold can be represented as a string of length L=1/kT
(thermostring). The thermostring swepts a surface in the space-time-temperature
manyfold at its temporal evolution. The thermostring is closed, its points can
be rearranged and the charge is distributed along the length. Some consequences
of this method for statistical mechanics and string theories are discussed.
