Centuries ago, Galileo Galilei observed a swinging lamp in the Pisa Cathedral and discovered the isochronism of the pendulum—that its period depends solely on its length, not its weight. This revelation laid the foundation for modern timekeeping, leading Christiaan Huygens to build the first accurate pendulum clock. Our interactive exhibit, "Snake Pendulum," allows you to experience this classic moment in physics history firsthand. The exhibit consists of a series of single pendulums with meticulously calculated lengths. When you press the button, all the pendulum balls are released simultaneously. You will observe that although they start swinging together, each moves at its own unique frequency due to the different lengths, soon forming an elegant and rhythmic wave pattern reminiscent of a slithering snake. This visually demonstrates the physical law that the period of a pendulum is proportional to the square root of its length. WhatsAPP?+86 18882709667 Email?zgzqkj@gmail.com
