First of all sorry for my poor English On page 59, Intersecting Rays with Spheres I'm a little confused ray's point at (0, 0, -5) but in figure looks like point at (-5, 0, 0), it's like the x-axis and z-axis are swapped Please give me some hints, I appreciate it.

I apologize for the illustration! The italic "z" I wrote on the horizontal label really does look like an "x", doesn't it? It really is supposed to be a "z", though, with the "x" axis moving perpendicularly out of the page.
