I read in a physics today paper,

The electron can have nonvanishing EDM only if nature violates symmetry under time reversal (T) and under the combined operations of charge conjugation (C), which replaces particle by antiparticle (as we all know), and parity inversion (P).

I checked here. So it will be nice if you can show me qualitatively and quantitatively about the above mentioned point.

Note: Simplicity in explanation is always nice. (I don't have much idea of these big words)

Hi lavkush. The question I've linked may not seem an obvious duplicate, but it's actually asking whether the electric dipole moment can be non-zero. Ignore my answer and read Rob's answer for the details. – John Rennie Jul 01 '14 at 13:49
@JohnRennie, answer seems to be complicated. But I tried to understand it. Doesn't match completely. Need more help. Either remove the flag, as nobody will answer then. – L.K. Jul 01 '14 at 14:29
