math notation
The thing between E1 and E2 looks like a hyphen, but I suspect it's intended to be a minus sign. Notice some differences:
 * E1-E2
 * E1 &minus; E2

The first thing above is a hyphen; the second is a minus sign.
 * $$ E_1\text{-}E_2 \, $$
 * $$ E_1 - E_2 \, $$

Again, the first thing is a hyphen and the second is a minus sign.

A minus sign is longer and has spaces before and after it.

Can the picture get fixed? Michael Hardy (talk) 16:37, 30 May 2012 (UTC)
