The universal truth no professor will admit: our relationship with mathematical symbols is purely emotional. That curly bracket {}, sitting up there in "high difficulty, moderate fun" territory—the symbol that makes you question your career choices during exam week. Meanwhile, infinity (∞) is just two loops away from pure joy. Notice how the Greek letters are scattered across the difficulty axis like shrapnel from a failed experiment. Phi (φ) and Omega (Ω) looking down on us mere mortals from their high-difficulty thrones. And of course, the integral symbol (∫) is the mathematical equivalent of that one coworker who's both annoying and somehow essential. The real heroes? Lambda (λ), mu (μ), and rho (ρ)—high fun, low difficulty. The symbols you actually want to write when you're seven espressos deep into problem set night.
