Dear all,(adsbygoogle = window.adsbygoogle || []).push({});

Here are some questions about explaining symbols in a journal paper.

a) Do you explain every symbol in the equations? For instance, when you write down Maxwell's equations in a journal paper, do you, after the equations say

"where [tex]\vec{E}[/tex] denotes the electric field, [tex]\vec{H}[/tex] denotes the magnetic field, [tex]t[/tex] is time, blah ... ..."

b) Once you have a symbol explained, do you use the symbol in line with the rest of the text or spell out the full name in the rest of the text? For instance, assume [tex]\vec{E}[/tex] has been defined, do you say "the time variation of [tex]\vec{E}[/tex] gives ... ..." or "the time variation of the electric field gives ... ..."?

These might sound a little silly, but the picture has never been quite clear.
