Math and Noah's Ark

These are a couple old (but new to me!) articles analyzing the Noah's ark/global flood story with a few back-of-the-envelope calculations.

The first figures out what we would expect if Creationist-style microevolution were actually true. Frightening stuff.

The second uses a video about the flood as a basis for some analysis of the speed of the floodwaters. They were, apparently, pretty fast.
