That innocent moment when you think physics is just about cool black holes, but then the mathematical stairway to hell reveals itself. Started with "ooh, space is neat!" and suddenly you're drowning in partial derivatives at 3 AM, questioning your life choices. The academic equivalent of opening a bag of chips and finding calculus-flavored vegetables inside. Trust me, even Stephen Hawking probably muttered "what have I done" while staring at his first differential equation.
