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
August 13, 2026 At the UChicago Precollege, Adrien and I teamed up to give a presentation on “Double-Slit Experiments and Quantum Mechanics.” We learned about the Schroedinger equation and qubits, but I didn’t really understand what they meant. While preparing for the presentation, I realized the Schroedinger equation describes the electron as a wave, and… Continue reading
