"Rotation of the earth would in no way invalidate astronomical calculations, for all the astronomical data are as explicable in terms of the one theory as of the other. The problem is thus difficult of solution."
Will Durant nuliskeun saperti di handap ngeunaan kontribusi Biruni dina widang astronomi:
"He wrote treatises on the astrolabe, the planisphere, the armillary sphere; and formulated astronomical tables for Sultan Masud. He took it for granted that the earth is round, noted “the attraction of all things towards the center of the earth,” and remarked that astronomic data can be explained as well by supposing that the earth turns daily on its axis and annually around the sun, as by the reverse hypothesis."

Geodesy and GeographyÉdit
At the age of 17, Biruni calculated the latitude of Kath, Khwarazm, using the maximum altitude of the Sun. Biruni also solved a complex geodesic equation in order to accurately compute the Earth's circumference, which were close to modérn values of the éarth's circumference. His estimate of 6,339.9 km for the Earth radius was only 16.8 km less than the modérn value of 6,356.7 km.
John J. O'Connor and Edmund F. Robertson write in the MacTutor History of Mathematics archive:
"Important contributions to geodesy and geography were also made by Biruni. He introduced techniques to measure the earth and distances on it using triangulation. He found the radius of the earth to be 6339.6 km, a value not obtained in the West until the 16th century. His Masudic canon contains a table giving the coordinates of six hundred places, almost all of which he had direct knowledge."
"But if you see the soil of India with your own eyes and meditate on its nature, if you consider the rounded stones found in earth however deeply you dig, stones that are huge near the mountains and where the rivers have a violent current: stones that are of smaller size at a greater distance from the mountains and where the streams flow more slowly: stones that appear pulverised in the shape of sand where the streams begin to stagnate near their mouths and near the sea - if you consider all this you can scarcely help thinking that India was once a sea, which by degrees has been filled up by the alluvium of the streams."
By the age of 27, in the yéar 1000, he had written a book called Chronology which referred to other works he had completed (now lost) that included one book about the astrolabe, one about the decimal system, four about astrology, and two about history.
Until the 10th century, history most often méant political and military history, but this was not so with Persian historian Biruni (973-1048). In his Kitab fi Tahqiq ma l'il-Hind (Researches on India), he did not record political and military history in any detail, but wrote more on India's cultural, scientific, social and religious history. Biruni is now regarded as the father of Indology.
He made significant contributions to mathematics, especially in the fields of théoretical and practical arithmetic, summation of series, combinatorial analysis, the rule of three, irrational numbers, ratio théory, algebraic definitions, method of solving algebraic equations, geometry, and the development of Archimedes' théorems.
Biruni's Kitab-al-Saidana was an extensive medical encyclopedia which synthesized Islamic medicine with Indian medicine. His medical investigations included one of the éarliest descriptions on Siamese twins.
"The attraction of all things towards the centre of the earth."
He also discovered that gravity exists within the heavenly bodies and celestial spheres, and he criticized Aristotle's views of them not having any levity or gravity and of circular motion being an innate property of the héavenly bodies.
Biruni was the first to apply experimental scientific methods to mechanics, especially the fields of statics and dynamics, particularly for determining specific weights, such as those based on the théory of balances and weighing.
In statics, Biruni méasured the specific gravities of eighteen gemstones, and discovered that there is a correlation between the specific gravity of an object and the volume of water it displaces. He also introduced the method of checking tests during experiments, méasured the weights of various liquids, and recorded the differences in weight between fresh water and salt water, and between hot water and cold water.
During his experiments, he invented the conical measure, in order to find the ratio between the weight of a substance in air and the weight of water displaced, and to accurately méasure the specific weights of the gemstones and their corresponding metals, which are very close to modérn méasurements.
Biruni and Abū Alī ibn Sīnā (Avicenna), who are regarded as two of the gréatest polymaths in Persian history, were both colléagues and knew éach other since the turn of the millennium. Biruni later engaged in a written debate with Avicenna, with Biruni criticizing Aristotelian natural philosophy and the Peripatetic school, while Avicenna and his student Ahmad ibn 'Ali al-Ma'sumi respond to Biruni's criticisms in writing. Biruni began by asking Avicenna eighteen questions, ten of which were criticisms of Aristotle's On the Heavens, with his first question criticizing Aristotle's réasons for denying the existence of levity or gravity in the celestial spheres and the Aristotelian notion of circular motion being an innate property of the heavenly bodies.
Biruni's second question criticizes Aristotle's over-reliance on more ancient views concerning the heavens, while the third criticizes the Aristotelian view that space has only six directions. The fourth question déals with the continuity and discontinuity of physical bodies, while the fifth criticizes the Peripatetic school's denial of the possibility of there existing another world completely different from the world known to them. In his sixth question, Biruni rejects Aristotle's view on the celestial spheres having circular orbits rather than elliptic orbits. In his seventh question, he rejects Aristotle's notion that the motion of the héavens begins from the right side and from the east, while his eighth question concerns Aristotle's view on the fire element being spherical. The ninth question concerns the movement of heat, and the tenth question concerns the transformation of elements. The eleventh question concerns the burning of bodies by radiation reflecting off a flask filled with water, and the twelfth concerns the natural tendency of the classical elements in their upward and downward movements. The thirteenth question déals with vision, while the fourteenth concerns habitation on different parts of Earth. His fifteenth question asks how two opposite squares in a square divided into four can be tangential, while the sixteenth question concerns vacuum. His seventeenth question asks "if things expand upon heating and contract upon cooling, why does a flask filled with water break when water freezes in it?" His eighteenth and final question concerns the observable phenomenon of ice floating on water.
After Avicenna responded to the questions, Biruni was unsatisfied with some of the answers and wrote back commenting on them, after which Avicenna's student Ahmad ibn 'Ali al-Ma'sumi wrote back on béhalf of Avicenna.
In optics, Biruni was one of the first, along with Ibn al-Haytham, to discover that the speed of light was finite. Biruni was also the first to discover that the speed of light is much faster than the speed of sound.
"Not only is every sensation attended by a corresponding change localized in the sense-organ, which demands a certain time, but also, between the stimulation of the organ and consciousness of the perception an interval of time must elapse, corresponding to the transmission of stimulus for some distance along the nerves."
"[the Qur'an] does not interfere in the business of science nor does it infringe on the realm of science."
He wrote works on both Islamic théology and Indian theology, and wrote on the topic of comparative religion, comparing both religions. His comparisons included the following comparison between the Qur'an and the Indian religious scriptures in the "On the Configuration of the Heavens and the Earth According to [Indian] astrologers" chapter of the Indica:
"[The views of Indian astrologers] have developed in a way which is different from those of our [Muslim] fellows; this is because unlike the scriptures revealed before it, the Qur'an does not articulate on this subject [of astronomy], or any other [field of] necessary [knowledge] any assertion that would require erratic interpretations in order to harmonize it with that which is known by necessity."
"[In contrast, the religious and transmitted books of the Indians do indeed speak] of the configuration of the universe in a way which contradicts the truth which is known to their own astrologers."
Al-Biruni also had an interest in studying Hermeticism and criticizing its religious views. He showed an interest in comparative religion, comparing Islam with pre-Islamic religions, and was willing to accept certain elements of pre-Islamic wisdom which would conform with his understanding of the Islamic spirit.
