Page 48 is blank

[MrYossu]

First off, thanks for making this fantastic book available for free! However, I found a problem.

The PDF version has a blank page where printed page 48 should be (this is page 76 as far as the PDF file goes). Page 47 starts section 1.2.2, then there's a blank page, then page 49 starts with figure 1.5, and then the continuation of a paragraph that is evidently missing.

Any ideas? Thanks again.
