SMARTPHONES AND PHYSICS Physics is a branch of science that deals with matter and energy, and plays a significant role in the capabilities of smartphones. In fact, you can thank physics for Bluetooth, cellular data, fast charging, and much, much more. Bluetooth was first invented in Sweden in the late 1990s to replace wired communications entirely. The science behind Bluetooth is relatively straightforward: the technology creates a personal area network (PAN) between devices over short wavelength radio waves in the air. This network is utilized to transmit data such as photos, videos, and sound to wireless
