Al-Biruni Physicist

Muhammad Ibn Ahmad Al-Bayrouni (973 - 1044) was an Arab astronomer, mathematician and geographer born in the village of Khuwarizm in present-day Uzbekistan. His studies and observations of the movements of celestial bodies resulted in him perfecting a new formula with which to calculate the circumference of the Earth, and a method for determining the direction of Mecca from anywhere on the planet. Al-Bayrouni accompanied the Sultan Mahmud of Ghazni in the latter's thirteen voyages to India, and spent four decades of his life there.

Impact crater
Al-Biruni is an impact crater that lies on the far side of the Moon, just beyond the eastern limb. This portion of the surface is sometimes brought into sight due to librations of the Moon, but due to its location the crater is viewed from the side. Al-Biruni lies to the south of the crater Joliot, and to the northeast of Goddard. The rim of Al-Biruni forms a somewhat irregular circle, with a slight outward bulge in the northeast wall, and a somewhat wider inner wall to the west. The interior floor is relatively flat, with a few tiny craterlets to mark the surface. The most notable of these is Al-Biruni C near the northeast wall.
