Everyone knows how long and painfully the science has gone to the irrefutable truth about the shape of the Earth and its rotation around the Sun. Giordano Bruno, Galileo Galilei tried to prove their point “And yet it moves”. Somebody was not believed and was given to the Inquisition, someone even after a round-the-world trip was subjected to doubts and criticism. However, in another part of the world, 500 years earlier, the medieval encyclopedic scientist Al-Beruni was able to calculate the radius of the Earth, mathematically proving that the Earth rotates and has a round shape.
