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.
