Complex Conjugate

[[A teacher is standing at a whiteboard covered in equations.]]
Teacher: Okay, anyone who's feeling like they can't handle the physics here should probably just leave now.
Teacher: Because I'm multiplying the wavefunction by its complex conjugate.
Teacher: That's right.
[[Dramatic zoom. It appears the teacher is writing on the side of the panel.]]
Teacher: Shit just got
