Engineers be like: "I've made a revolutionary discovery!" *drumroll* It's the number 3! 😮
This is poking fun at how some engineering students (especially mechanical ones) get super excited about π/3 or e ≈ 3 as approximations in calculations. Meanwhile, mathematicians are having collective heart attacks at such blasphemy! The shocked Kung Fu Panda face perfectly captures that "eureka" moment when someone thinks they've invented something groundbreaking that's actually been around forever.
