Nothing makes an engineer's heart flutter like those sweet nothings whispered in thermodynamics class. "Assume ideal gas" is basically foreplay in the physics world. These magical phrases are what let us pretend our messy, chaotic universe behaves according to our neat little equations. Sure, real gases are clingy and complicated, fluids are stubborn, and friction ruins everything—but in our perfect paper world, none of that exists! It's the scientific equivalent of "let's ignore our problems and pretend everything's fine." No wonder we fall in love with these simplifications. They're the only relationships that don't disappoint us.
