I'm re-reading the thread, and still having the same objections to the literacy problem inherent in Grassie's proposal. But on a more practical level, I can see that at this point we've got both the wiki concept and informational graphics training working sufficiently well to have a go at a distributed, graphic (strictly non-verbal) version of Maps of Time. That is, as long as we don't get to the point of "My hard copy? I thought YOU were making a hard copy of it!" if TSHTF rather suddenly.
My inclination, however, is to get the very basic stuff covered first before atoms and galaxies. This is how you make soap. Wash your hands before handling food, after handling the sick or using the latrine, which you've placed away from your clean water source. There are ways of breathing that can get you through some situations, like childbirth. Abacus, plant and animal breeding, food combos that provide complete proteins. Spinning and crochet.
