A wonderful coincidence or an expected connection: why π² ≈ g
The text discusses the approximate equality between π² (about 9.87) and the acceleration due to gravity (g, about 9.81 m/s²), exploring the connection between these numbers through unit definitions and historical measurement standards. It explains the challenges in standardizing measurement units and how the definition of the meter evolved, particularly with reference to the pendulum proposed by Christiaan Huygens. Ultimately, while π² and g align closely, the differences arise from changes in how the meter is defined and measured over time.
