In a world-first, researchers from the Australian National University in Canberra have used simple wave generators to drag floating objects around in a body of water, even getting them to move against the direction of the waves. . . . It sounds so simple - in fact, you can recreate the experiment at home - but even the scientists who achieved the technique can’t explain the mathematics behind it. Its one of the great unresolved problems, yet anyone in the bathtub can reproduce it, said one of the team, physicist Horst Punzmann. We were very surprised no one had described it before.
