Lol - you've been watching the Big Bang Theory comedy show when Penny wanted to know if she should go out on a date with Leonard!
Sheldon explains it as Schrodinger's Cat Theory - where a cat is locked inside a cardboard box with a small piece poisoned food for a short time.You don't know if the cat is dead from eating this or still alive inside the box.And the only way to find out, is to open up the box.It's a clever way of saying "You won't know til you find out" - hence Sheldon giving Penny the advice about her date.
