Paragraph on units.
This section starts with a short diversion to a simplified equation when natural units are used (c=1) but this is not relevant to units. If E^2 = p^2 + m^2 (as suggested by the author) then the units are incorrect because they do not match the dimensionality. 'Natural Units' is an abomination introduced by some authors to simplify their equations but confusing the units of the quantities.

My statement can be verified by the original text. The natural units equation sets E, p and m in the same equation without any other constants so they HAVE to have the same dimensionality which means mass (g) cannot be equated to momentum (g.cm.s^-1). This section would be greatly improved by removing the mention of natural units completely.
