One memory I couldn't pinpoint was a short story about a group of astronomers on a planet with dual suns. Every few thousand years their civilization would start from scratch when they would have a total solar eclipse and people would go crazy and destroy everything. The astronomers were prepared for the masses to destroy everything around them but were determined to keep sane. But they also went nuts when the eclipse happened.
Can't remember the title or the author.
