#Applied Physics

Applied physics is what happens when the theoretical laws of physics meet practical problems — building bridges that don’t collapse, designing lasers, predicting weather, getting GPS satellites to agree with clocks on the ground (which requires correcting for special and general relativity). The posts collected under this tag cover the practical side: how physics shows up in engineering, medicine, space exploration, computing, and the everyday devices most people never realize are governed by the same equations that describe stars.
