When I saw "celestial sphere" in the astronomy section, I really hoped it was going to peddle the renaissance view that the heavens consist of concentric crystal spheres. Alas.

It's odd that their section on 'circular reasoning' notes, in summary, that "Christian scientists rely on presuppositions based on the Bible, while secular scientists do not". By their own definitions and explanations, this seems to gravely undermine their notion of faith-based science. It's also rather a slight against the many fine scientists whose religious beliefs don't interfere with their research.

It's sad and a little frightening that this kind of work is still circulated in an educated, first-world country. Sure, it's covered by free speech and religious freedom laws, but beyond that I would have hoped that education, reason and religion would have evolved to the point where it's no longer necessary. By and large, I guess this is the case in most of our countries. It's only a handful of outlying denominations that are still clinging to this kind of backward fundamentalism; hopefully attrition and the natural advantages provided by a real education will gradually whittle away at what little support these groups still have.
