These handle the words in the text.

Math identifiers: E m c .

The page number; presumably 1 .

The superscripted 2 .

Because anything written in math mode obeys a different set of typesetting
rules to what is used in ordinary text. This involves spacing, positioning and
sizing of super- and subscripts as well as choice of font face for each class
of character or symbol. This is what makes TeX output look so much more
attractive than what any other software produces.
To change things, you'll need to study the mathspec or unicode-math
packages, if I've got the names correct. Otherwise study the LaTeX Companion,
for ways to handle Math Alphabets using non-XeTeX methods, which should still
work, but with a limited range of fonts.
