Only Earth Things on Instagram: "Engineers invented the silencer (suppressor) by studying how expanding gases create sound, then designing chambers and baffles that slow and cool those gases before they escape. The result was a dramatic reduction in noise and flash — a concept rooted in physics and materials science that reshaped engineering discussions around sound control and technology (history and theory only, not a how-to). #EngineeringHistory #SoundSuppression #PhysicsInAction #DidYouKnow
