Pocket Physics Lab
Your phone contains classical mechanics in the accelerometer, electromagnetism in antennas and charging, relativity in GPS corrections, and quantum physics in the camera sensor.

Newton, Faraday, Maxwell, Einstein, and Bohr all contributed foundational work to the device in your pocket. Your smartphone is not just a gadget — it is a monument to cumulative human understanding, miniaturized into something that fits in your hand.
