Two identical tuning forks mounted on resonance boxes are struck with rubber mallets to show they have identical tones. A small piece of putty is added to one tuning fork to alter it's frequency. When ...

Researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave “tuning fork.” The team’s findings could also ...

Superfluid helium represents a fascinating state of matter, manifesting unique quantum mechanical behaviours at ultralow temperatures, including frictionless flow and the absence of viscosity. In ...
