(When you do this calculation, make sure you use the same units, like meters, for all of them.) For someone like me, my eyes are about 1.65 meters above sea level, and I can see that buoy start to disappear when I'm about 4,600 meters away from it. If you can accurately measure the distance from you to the buoy (call it D) and the height of your eyes above sea level (call it h), you can use a simple mathematical formula based on right triangles to calculate R, the radius of the Earth. He measured the dip angle using an astrolabe and he applied to the law of sines formula. The idea came to him when he was on top of a tall mountain near Nandana in India. the Earth radius had an error of 0.0026 and was 16.8 km less than the current value of 6,356.7 km. The method of Biruni for calculating the Earth's circumference.
