For more than a century, physicists debated which way a submerged sprinkler sucking in water would spin. Careful experiments ...

Researchers at RPTU University Kaiserslautern-Landau have achieved a key experimental breakthrough: For the first time, the spontaneous macroscopic coherence of magnons—the quantized excitations of ...

For decades, physicists have argued about Feynman’s Sprinkler Problem, the question of how a reverse sprinkler would operate.
