Each floor of a 100-story building has a balcony over which you can drop an egg and watch it hit the ground. The egg either breaks or survives the fall (and if it survives, it can be used again for another drop). You want to classify each floor as either an egg-breaking floor or a non-egg-breaking floor, and you have just two eggs for this job! What is the least number of egg-drops you should plan for in order to classify each and every floor? (Is it even, for sure, possible to do so?)
I offer my emotional reactions and personal process for thinking about this puzzle.
