Cross-disciplinary Memes

That moment of scientific cross-disciplinary recognition that no one else gets. While physics students know Josiah Willard Gibbs for his work in optics, chemistry students worship him as the thermodynamics deity who gave us the Gibbs free energy equation. It's like spotting your favorite obscure band's t-shirt in public—except instead of music, it's equations that determine whether reactions are spontaneous. The silent nod of recognition while everyone else wonders why you're so excited about some random 19th-century dude.
