Thus there would be no need for the systems of CGSE units, CGSM units and the Gaussian units
. Replacing the dimensions and introducing new electromagnetic constants is a purely technical problem, although it is hardly practicable today.
where the plasma frequency (in Gaussian units
) is given by
He provides information on physical constraints, useful vector identities, and Gaussian units
in appendices, provides a concise list of further reading, and supplies summaries at the beginning and exercises at the end of every chapter.
Thus [r.sub.*][m.sub.*]/[e.sup.2.sub.*] in (9) had better equal [10.sup.-7] in mks units, and it does ([e.sub.*] in Gaussian units is obtained from (3) and G, or from (7) and h; and then changed into mks units for the calculation).
Shifting (8) and (9) out of mks units back into Gaussian units leads to 2
