Some suggestions for clarity

[dhruvp]

This was an amazing post that must have taken months. Thank you first of all for putting it together! I had some suggestions for how to make it clearer for a larger audience that would only take a few minutes to implement:

1. Add a caption discussing what changed between the two images and how that helps us see that the dimensions act independently (and what does it mean for the dimensions to act "independently"). Right now it's unclear what the purpose of that image is in the explanation.

2. I had trouble following the steps to arriving at the condition number. If you could just add a few more steps to walk us through that'd be awesome.

Thanks!
