Experiment with a Watch Movement (oscillation period)
August 22, 2026 I have been playing with the recently bought mechanical watch movement toy almost every day. I decided to do a simple experiment with it. As the mainspring unwinds, it moves the escapement and then the balance wheel, which oscillates. I wanted to test if the oscillation period of the balance wheel stays… Continue reading

Double-Slit Experiment and Quantum Mechanics

Watch Movement
August 8, 2026 I got this new toy from Amazon. It is a 3D-printed model of a mechanical watch movement. It is amazing. This 3D-printed thing actually works like a real machine! Once I wind and release it, it starts making a regular tick-tock, tick-tock sound. This is probably the central part of a mechanical… Continue reading
