Ptolemy assumed an arrangement hay'a that cannot exist, and the fact that this arrangement produces in his imagination the motions that belong to the planets does not free him from the error he committed in his assumed arrangement, for the existing motions of the planets cannot be the result of an arrangement that is impossible to exist Experiments with mirrors and the refractive interfaces between air, water, and glass cubes, hemispheres, and quarter-spheres provided the foundation for his theories on catoptrics.

In his Opuscula , Alhazen considers the solution of a system of congruences, and gives two general methods of solution. Alhazen's determination to root astronomy in the realm of physical objects was important, however, because it meant astronomical hypotheses "were accountable to the laws of physics ", and could be criticised and improved upon in those terms. Retrieved 2 June It took an additional three centuries under the watchful eye of the law of sines was proposed by Snell and Descartes. Toomer expressed some skepticism regarding Schramm's view, [82] partly because at the time the Book of Optics had not yet been fully translated from Arabic, and Toomer was concerned that without context, specific passages might be read anachronistically. This mathematical-physical approach to experimental science supported most of his propositions in Kitab al-Manazir The Optics ; De aspectibus or Perspectivae [78] and grounded his theories of vision, light and colour, as well as his research in catoptrics and dioptrics the study of the reflection and refraction of light, respectively. Therefore he concludes that only some physical effect of the sun's light rays on the moon renders the latter's color visible.

Following on from his Doubts on Ptolemy , Alhazen described a new, geometry-based planetary model, describing the motions of the planets in terms of spherical geometry, infinitesimal geometry and trigonometry. Without tangible notions of distance and size for correlation, sight can tell us next to nothing about such things. His field work, however, later made him aware of the impracticality of this scheme, and he soon feigned madness so he could avoid punishment from the Caliph. He developed a formula for summing the first natural numbers, using a geometric proof to prove the formula. Alhazen offered an explanation of the Moon illusion , an illusion that played an important role in the scientific tradition of medieval Europe. Distances from a point of a triangle to its sides 3.

His solution was extremely long and complicated and may not have been understood by mathematicians reading him in Latin translation. Ibn al-Haytham was the first to explain that vision occurs when light reflects from an object and then passes to one's eyes. Alhazen's contributions to number theory include his work on perfect numbers. It is stationary in its [the world's] middle, fixed in it and not moving in any direction nor moving with any of the varieties of motion, but always at rest. In his essay "On the Form of the Eclipse" he writes that he observed the sickle-like shape of the sun at the time of an eclipse. He held that the criticism of existing theories—which dominated this book—holds a special place in the growth of scientific knowledge. This fifth volume of A History of Arabic Sciences and Mathematics is complemented by four preceding volumes which focused on the main chapters of classical mathematics: infinitesimal geometry, theory of conics and its applications, spherical geometry, mathematical astronomy, etc. Most of his works are now lost, but more than 50 of them have survived to some extent.

The obvious answer to the problem of multiple rays and the eye was in the choice of the perpendicular ray, since only one such ray from each point on the surface of the object could penetrate the eye. A Latin translation of the Kitab al-Manazir was made probably in the late twelfth or early thirteenth century. Al-Haytham's contributions to geometry and number theory went well beyond the Archimedean tradition.

    International Journal of Optics and Applications 2014, 4(4): 110-113 DOI: 10.5923/j.optics.20140404.02 Alhazen, the Founder of Physiological Optics and Spectacles Nāsir pūyān (Nasser Pouyan) Tehran, 16616-18893, Iran Abstract Alhazen (c. 965 – c. 1039), Arabian mathematician and physicist with an unknown actual life who laid the foundation of physiological optics and came within an ace of discovery of the use of eyeglasses. He wrote extensively on algebra, geometry, and astronomy. Just the Beginnings of the 13th century, in Europe eyeglasses were used as an aid to vision, but Alhazen’s book “Kitab al – Manazir” (Book of Optics) included theories on refraction, reflection and the study of lenses and gave the first account of vision. It had great influence during the Middle Ages. In it, he explained that twilight was the result of the refraction of the sun’s rays in the earth’s atmosphere. The first Latin translation of Alhazen’s mathematical works was written in 1210 by a clergyman from Sussex, in England, Robert Grosseteste (1175 – 1253). His treatise on astrology was printed in Latin at Basle in 1572. Alhazen who was from Basra died in Cairo at the age of 73 (c. 1039).

  • Exploration of the Moon
    Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth. Apollo 12 Lunar Module Intrepid prepares to descend towards the surface of the Moon. NASA photo. Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms.

  • Alhacen's Theory of Visual Perception: a Critical Edition, With
    Alhacen’s Theory of Visual Perception: A Critical Edition, with Eng- lish Translation and Commentary, of the First Three Books of Alha- cen’s De Aspectibus, the Medieval Latin Version of Ibn al-Haytham’s Kit¯abal-Man¯az.ir by A. Mark Smith Transactions of the American Philosophical Society 91.4–5. Philadel- phia: American Philosophical Society, 2001. Pp. clxxxi+819. ISBN 0– 87169–914–1. Paper $32.00 Reviewed by Glen M. Cooper Brigham Young University [email protected] Before launching into a review of this fine edition, a brief discussion of the name ‘Alhacen’ is in order. Most scholars are used to seeing the Latin form of the name of the Arab scientist, Ab¯u cAl¯ıal-Has.an ibn al-Has.an ibn al-Haytham, or Ibn al-Haytham, as ‘Alhazen’. But, as Professor Smith argues, Alhacen is an attested form in the Latin, and is closer to al-Has.an, one of his names (as long as the ‘c’ is given a ‘soft’ ‘s’ sound). In fact, according to Smith, the form ‘Alhazen’ does not appear later, and seems to originate with Risner [1572] in his edition of the Optica. Though as an Arabist I would prefer to refer to Alhacen as Ibn al-Haytham, for the sake of consistency and in harmony with Smith’s edition, I shall refer to him as Alhacen throughout. Professor Smith has been active in the field of the history of optics since at least the 1980s. He has published several excellent articles and editions and is certainly well-qualified to produce the present edition.

  • An Analysis of the Contributions of the Medieval Muslim Scholars to Medical Science
    Manarat International University Studies, 5(1), 2015 ISLAM AND MODERN SCIENCE: AN ANALYSIS OF THE CONTRIBUTIONS OF THE MEDIEVAL MUSLIM SCHOLARS TO MEDICAL SCIENCE Dr. Muhammad Obaidullah ABSTRACT The primary objective of this paper is to depict the real-time contributions made by the Muslim scientists and researchers in the area of medical science during the medieval period. Many inscribed write-ups, books and Encyclopedias have been written and published on the various areas of medical science by the eminent Muslim scholars during the medieval period. It is acknowledged by the prominent scientists, historians and philosophers that the contributions of Muslim researchers prevalently shaped the science and philosophy into the form that we see it today. However, there is a tendency in the western society to ignore the contribution of Muslim scientists in the historical development of medical science. Western writers have given little prominence to Islamic Scientific and intellectual contributions to this field. But the fact is that the Muslims carried the torch of science in an age when no other civilization was capable of doing so. The current study would also shed light on the underlying reasons as to why Muslims today are not able to contribute to the development of sciences including the medical science like their golden age. This will conclude by furnishing some suggestions to improve the current devastating state of Muslims in the development of sciences. The methodologies applied in this study are descriptive and analytic. Keywords: Science, Medical Science, Scientist, West, Islam & Muslim, 1. INTRODUCTION From the very beginning Islam encouraged the pursuit of science and favored progress.

Alhazen was the greatest and most influential contributor to Western Europe science of optics.ed1 b. Ibn al-Haytham used experimental evidence to develop a remarkably accurate theory of vision.2 He introduced the scientific method. 2. Kitab al-Manazir or Book of Optics a. Alhazen’s Kitab al-Manazir or the Book of Optics, was published sometime between 1028 [418 A.H.] and 1018 [429 A.H.] and was incorporated throughout the core of post-medieval Western culture.3 b. It was introduced to the West about 1200 and became the prime source for thirteenth century optical investigators.7345 c. The book initiated a chain of development of the modern understanding of optics as well as understandings of two dimensional pictorial representations of three dimensional space.6 d. The translation of the Book of Optics was absorbed by medieval optical scientists, Roger Bacon, Erazmus Witelo, and John Pecham, whose subsequent work had enormous influence on the progression of optical understandings throughout the centuries that immediately followed.7 e. Ghiberti contributed to Alberti’s discussion about a decade later and relied heavily optical theories of Pecham and Witelo, which relied heavily on Alhazen.8 f.

  • Science in the Medieval Islamic World Was the Science Developed And
    Science in the medieval Islamic world was the science developed and practised during the Islamic Golden Age under the Umayyads of Córdoba, the Abbadids of Seville, the Samanids, the Ziyarids, the Buyids in Persia, the Abbasid Caliphate and beyond, spanning the period roughly between 786 and 1258. Islamic scientific achievements encompassed a wide range of subject areas, especially astronomy, mathematics, and medicine. Medieval Islamic science had practical purposes as well as the goal of understanding. For example, astronomy was useful for determining the Qibla, the direction in which to pray, botany had practical application in agriculture, as in the works of Ibn Bassal and Ibn al-'Awwam, and geography enabled Abu Zayd al- Balkhi to make accurate maps. Islamic mathematicians such as Al- Khwarizmi, Avicenna and Jamshīd al-Kāshī made advances in algebra, trigonometry, geometry and Arabic numerals. Islamic doctors described diseases like smallpox and measles, and challenged classical Greek medical theory. Al-Biruni, Avicenna and others described the preparation of hundreds of drugs made from medicinal plants and chemical compounds. Islamic physicists such as Ibn Al-Haytham, Al-Bīrūnī and others studied optics and mechanics as well as astronomy, criticised Aristotle's view of motion. The significance of medieval Islamic science has been debated by historians. The traditionalist view holds that it lacked innovation, and was mainly important for handing on ancient knowledge to medieval Europe. The revisionist view holds that it constituted a scientific revolution. Whatever the case, science flourished across a wide area around the Mediterranean and further afield, for several centuries, in a wide range of institutions.
