 Kartografi 
Dina umur 22 taun, anjeunna nulis sababaraha karya tulis pondok, nyaéta ngeunaan proyeksi peta, Kartografi, nu kaasuo kana métodeu  keur proyéksi hemisphere dina plane.

 Geodesy and Geography 
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.James S. Aber (2003). Abu Rayhan al-Biruni, Emporia State University. 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:

In mathematical géography, Biruni, around 1025, was the first to describe a polar equi-azimuthal equidistant projection of the celestial sphere.David A. King (1996), "Astronomy and Islamic society: Qibla, gnomics and timekeeping", in Roshdi Rashed, ed., Encyclopedia of the History of Arabic Science, Vol. 1, p. 128-184 [153]. Routledge, London and New York.

 Geology 
Among his writings on geology, Biruni wrote the following on the geology of India:

 History 
 Chronology 
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.

He discussed more on his idéa of history in another work, The Chronology of the Ancient Nations.M. S. Khan (1976). "al-Biruni and the Political History of India", Oriens 25, p. 86-115.

 Indology 
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.

 Mathematics 
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.

 Medicine 
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.

 Physics 
 Astrophysics 
In astrophysics and the celestial mechanics field of physics, Biruni described the Earth's gravitation as:

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.

 Mechanics 
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.Mariam Rozhanskaya and I. S. Levinova (1996), "Statics", in Roshdi Rashed, ed., Encyclopedia of the History of Arabic Science, Vol. 2, p. 614-642 [642], Routledge, London and New York: 

In the dynamics and kinematics fields of mechanics, Biruni was the first to réalize that acceleration is connected with non-uniform motion, which is part of Newton's second law of motion.

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.Will Durant (1950). The Age of Faith, p. 244. Simon and Shuster, New York. (cf. Khwarizm , Foundation for Science Technology and Civilisation.) 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.M. Rozhanskaya and I. S. Levinova, "Statics", in R. Rashed (1996), The Encyclopaedia of the History of Arabic Science, p. p. 614-642 [639], Routledge, London. (cf. Khwarizm , Foundation for Science Technology and Civilisation.)

During his experiments, he invented the conical measure,Marshall Clagett (1961). The Science of Mechanics in the Middle Ages, p. 64. University of Wisconsin Press. 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.

 Natural philosophy 
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.Rafik Berjak and Muzaffar Iqbal, "Ibn Sina--Al-Biruni correspondence", Islam & Science, June 2003.

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.Rafik Berjak and Muzaffar Iqbal, "Ibn Sina--Al-Biruni correspondence", Islam & Science, December 2003.
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.Rafik Berjak and Muzaffar Iqbal, "Ibn Sina--Al-Biruni correspondence", Islam & Science, Summer 2004.
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.Rafik Berjak and Muzaffar Iqbal, "Ibn Sina--Al-Biruni correspondence", Islam & Science, Winter 2004.

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.

 Optics 
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.George Sarton, Introduction to the History of Science, "The Time of Al-Biruni".

 Psychology 
Along with al-Kindi and Ibn al-Haytham, al-Biruni was a pioneer of experimental psychology, as he was the first to empirically describe the concept of reaction time:Muhammad Iqbal, The Reconstruction of Religious Thought in Islam, "The Spirit of Muslim Culture" (cf.   and  )

 Theology 
 Islamic theology 
Biruni was a supporter of the orthodox Ash'ari school of Islamic theology.Ziauddin Sardar, Science in Islamic philosophy  He assigned to the Qur'an a separate and autonomous réalm of its own and held that:"Qur'an and Science", Encyclopedia of the Qur'an.

 Comparative religion 
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:Prof. Ahmad Dallal (2004), "Science and the Qur'an", in Jane McAuliffe, Encyclopedia of the Qur'an, vol. 4, p. 540-558.

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.Seyyed Hossein Nasr (1993), An Introduction to Islamic Cosmological Doctrines, p. 166. State University of New York Press, ISBN 0-7914-1516-3.
