A tuning fork (mounted on a resonance box) is made to resonate when a second identical tuning fork is rung nearby. This is beacause the first tuning fork's driving frequncy is the same as the second ...

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 ...

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 ...

[Willem Koopman aka Secretbatcave] was looking at a master clock he has in his collection which was quite a noisy device, but wanted to use the matching solenoid slave clock mechanism he had to hand.

In a curious inquiry, a reader sparks a cosmic conversation by questioning whether a tuning fork struck in the void of space could forever produce vibrations. Is that possible? Before we delve into ...
