Typo and suggestion #72

Specifically on this section:

... in which each component of acts ...

I'm not sure which component of what. It's missing the object of the preposition "of".

Also in that section, you refer to the eigenvectors of R, \sigma_1 and \sigma_2. Because there's no Oxford comma, I thought the sigmas were the eigenvectors of R. But the "type/shape checking" against the other expressions suggest that the sigmas are scalar. I assume those are the eigenvalues of R?

In an unrelated note: really great article.

Edit: Looks like some of my comments overlap with #68.

I think everything is resolved! Thank you for your comments.
