From a Psychology textbook I read (and other sources, including here): "Elaborative Rehearsal" is a kind of reviewing that improves retention: instead of just rereading atomic "facts"

I'm my experience psychology literature does not easily present atomic facts. Finding atomic facts in a article is a process that means that you have to understand what the article is about.

I took a book about learning theory and it told stories about how Aristotle did this and that and how some experiment turned out in a specific way. It names a bunch of facts but I didn't found anything that looked like an atomic fact in the first two chapters.
