Hannes Olof Gösta Alfvén (May 30, 1908; Norrköping, Sweden – April 2, 1995; Djursholm, Sweden) was a Swedish plasma physicist and Nobel laureate for his work on the theory of magnetohydrodynamics. He was originally trained as an electrical power engineer and later moved to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth's magnetic field, the terrestrial magnetosphere, and the dynamics of plasmas in the Milky Way galaxy.In order to understand the phenomena in a certain plasma region, it is necessary to map not only the magnetic but also the electric field and the electric currents. Space is filled with a network of currents which transfer energy and momentum over large or very large distances. The currents often pinch to filamentary or surface currents. The latter are likely to give space, as also interstellar and intergalactic space, a cellular structure.  1970-Hannes AlfvèN-Plasma Physics, Space Research And The Origin Of The Solar System*
