The folks at WIRED have put together a great video for the science nerds among us—and I do have a feeling there are a few. The video, which is part of WIRED's Dot Physics series, explains the physics behind drone flight; in other words: how that new DJI Mavic Air and quadcopters like it are able to hover, move in three dimensions, and rotate all by changing the speed at which various propellers spin.

This explains why your quadcopter doesn't need any other sort of physical controls, just four propellers—two spinning clockwise, two spinning counterclockwise—that change the rate at which they spin based on signals from your remote control.
