A wonderful coincidence or an expected connection: why π² ≈ g.

Let’s take a brief trip back to our school years and recall some lessons in mathematics and physics. Do you remember what the number π equals? And what is π squared? That’s a strange question too. Of course, it’s 9.87. And do you remember the value of the acceleration due to gravity, g? Of course, that number was drilled into our memory so thoroughly that it’s impossible to forget: 9.81 m/s². Naturally, it can vary, but for solving basic school problems, we typically used this value.
