"Alfvén said: “The cosmical plasma physics of today . . .is to some extent the playground of theoreticians who have never seen a plasma in a laboratory. Many of them still believe in formulas which we know from laboratory experiments to be wrong . . . several of the basic concepts on which theories of cosmical plasmas are founded are not applicable to the condition prevailing in the cosmos. They are ‘generally accepted’ by most theoreticians, they are developed with the most sophisticated mathematical methods; and it is only the plasma itself which does not ‘understand’ how beautiful the theories are and absolutely refuses to obey them. . .”"Still true.
