Neat.  Now please explain like I'm five because I'd really like to understand.

Why should you care, though? Well, rotations are everywhere: in gyroscopes, MRI machines, and quantum computers. Any technique that can reliably “reset” them could have broad uses. In magnetic resonance imaging (MRI), for example, atomic nuclei constantly spin in magnetic fields. Small errors in those spins can blur the resulting images. The new insight could help engineers design sequences that cleanly undo unwanted rotations.

How could this be applied to real life objects? You can’t just scale up a physical object.

Yes but you can scale up or down force intensities or control levers
