Superposition describes when something exists in multiple states at once. Think of it like a coin spinning in the air β it's both heads and tails until it lands. In quantum mechanics, particles can be in multiple places simultaneously until observed. It's not just uncertainty; it's a real combination of possibilities. This idea isn't just physics; consider a difficult decision where you're both willing and unwilling to do something. Superposition collapses when you make a choice.
