Physics students know the pain! You're reading a textbook and suddenly "Schwarzschild and Epstein" appears, and your brain does that thing where it recognizes names but has no clue what they actually did. The Stark effect? Something about hydrogen atoms in electric fields? Sure, whatever you say, textbook! Then you nod knowingly to hide your confusion while frantically Googling under the table. The real quantum uncertainty is whether anyone in the room actually understands what they're reading or if we're all just pretending. Fun fact: The Stark effect they're talking about is the splitting of spectral lines when atoms are placed in electric fields - basically atoms getting their energy levels messed up when electricity crashes their party. Revolutionary in 1916, but the real achievement was fitting so many intimidating terms into one paragraph!
