70 seconds to load a chapter? That's a terrible benchmark for even for some of the heaviest websites out there! This may not be a popular opinion but I (and many ordinary readers like me) see that link as a website. Not a book. It feels heavy and overwhelming to see a large number of 3D diagrams and visual depictions on just one web-page. Having to scroll down to read the full chapter with all that animation and "motion" is probably a bad move too. Given that this is supposed to come off like a book you can probably ditch the scroll. Ideally, you'd want to give away few concepts in small easy-to-understand chunks with just 1 or 2 figures per page. And let the reader flip/click over to the next section like it happens with an ibook or kindle book or even a real physical book. IMHO the idea of ripping apart a book at its spine and forcing the loose design of websites over it is a complete no-go for avid book readers. Especially for the mobile and tablet users (probably even for the desktop users!, why else would everyone insist to download PDF, ePub or other artifacts?). But I'm sure that a section of developers over here wouldn't agree with my opinion. So take it all with a pinch of salt. Also just the place where I'd let the designers take over.
