That face when you're staring down one of math's greatest unsolved problems! The Riemann Hypothesis—basically math's final boss—states that all those weird non-trivial zeros of the zeta function have a real part of exactly 1/2. Mathematicians have verified BILLIONS of cases, but no one's managed a proof yet. It's like knowing the answer to the universe but not being able to show your work. A million-dollar prize awaits whoever cracks it, so that intense stare is just the look of someone contemplating early retirement via pure mathematics. The struggle is real ... well, exactly 1/2 real, technically speaking.
