SUMMARY
The Foucault pendulum serves as definitive evidence of Earth's rotation, demonstrating that the plane of oscillation shifts due to the Earth's movement. Observations such as the apparent motion of stars and parallax further support this conclusion. Calculating the pendulum's revolution time based on latitude provides additional insights, particularly when comparing locations like the North Pole and the equator. Time-lapse images of star fields from different poles illustrate the rotation of the Earth against a stationary star field.
