Links Personalities Tour (Next) Previous Ibn Yunus Tour (Next) Ibn Yunus Pages Ibn Yunus Astrology Mathematical Techniques Astronomical Tables General Pages Home Index Ibn Yunus Ibn Yunus (950?-1009) was born in Islamic Egypt and served the Fatimid dynasty for twenty-six years. His most famous work, al-Zij al-Hakimi al-kabir , is notable for its very accurate tabulated results. These may have been obtained using very large instruments. Abu'l-Hasan 'Ali Ibn 'Abd al-Rahman Ibn Ahmad Ibn Yunus al-Sadafi came from a respected family in Fustat, his great grandfather having been a companion of the famous legal scholar al-Sahfi and his father being a distinguished historian and scholar of hadith (the sayings of Muhammad). Little is known about his early life or education. Indeed, his date of birth is not known, although 950 has been suggested. As a young man Ibn Yunus witnessed the Fatimid conquest of Egypt and the foundation of Cairo in 969 (Fustat was just outside the new city of Cairo). He served two Caliphs of the dynasty, al-Aziz and al-Hakim, making astronomical observations for them between 977 and 1003. To the second, al-Hakim, he dedicated his major work al-Zij al-Hakimi al-kabir (a zij is an astronomical handbook with tables). He died in 1009.

We know little of ibn Yunus's childhood but we do know that he grew up in a period of military conquest in Egypt. The Fatimid political and religious dynasty took its name from Fatimah, the daughter of the Prophet Muhammad. The Fatimids headed a religious movement dedicated to taking over the whole of the political and religious world of Islam. As a consequence they refused to recognise the 'Abbasid caliphs. The Fatimid caliphs ruled North Africa and Sicily during the first half of the 10 th century, but after a number of unsuccessful attempts to defeat Egypt, they began a major advance into that country in 969 conquering the Nile Valley. They founded the city of Cairo as the capital of their new empire. Ibn Yunus was closely connected with the Fatimids and two Caliphs supported his scientific work. The first of these Caliphs was al-Aziz, who was the first of the Fatimid caliphs to begin his reign in Egypt. Al-Aziz became Caliph in 975 on the death of his father al-Mu'izz and, two years later, ibn Yunus began to make astronomical observations. Although there is uncertainty about the instruments that ibn Yunus used, it is claimed by early writers that al-Aziz provided ibn Yunus with at least some instruments.

For the sake of convenience, I divide Muslim mathematicians into three groups: those of the West, those of Egypt, who occupied, so to speak, an intermediate position, and those of the East. This is also a logical division, for though communications between the eastern and western ends of the Islam were frequent (there were a number of itinerant scholars to whom the universality of Islam seems to have been a continual provocation to move on from place to place), it is clear that local influences were felt more constantly and to greater advantage. I named these Eastern mathematicians, as well as possible, in chronological order. This does not, perhaps, bring out with sufficient clearness the full complexity of their activities. In the first place, observe that, I did not mention a single astrologer; only one named in this section flourished not in the East, but in the orthodox Tunis, where there was much less freedom of thought. In the second place, if we leave out of account the astronomical work, which was determined by practical necessities, we find that there were two distinct streams of mathematical thought: the one theoretical represented by Ibn al-Husain, Abu-l-Jud, and al-Karkhi, the other, more practical, represented by al-Nasawi and Ibn Tahir. Al-Biruni and Ibn Sina can not be included in that classification, for they were equally in the most abstruse and in the most practical questions; they had no contempt for humble means, for there are no small matters for great minds.

There was no retrogression, but the advance of mankind, which had been so vigorously accelerated during the ninth century through the youthful energy of Islam, was then distinctly slowed up. It is not the first time that we thus witness a momentary quieting down of human activity; on the contrary, we have already had occasion to observe many such periods of fallow. e. g., the first half of the second century B. C., the second half of the fifth, the second half of the sixth, the second half of the seventh, the first half of the eighth. But in each case the slowing up was followed by a new acceleration. To come back to the second half of the tenth century, we shall see presently that it was a period of renewed activity in almost every field; the partial fallowness of the first half of the century was thus amply rewarded by more abundant crops and mankind was able to make a few more leaps forward.

Mathematician Report Index Below is a list of mathematicians. You may choose from this list or report on a mathematician not listed here. In either case, you must discuss with me the mathematician you have chosen prior to starting your report. No two students may write a report on the same mathematician. I would advise you to go to the library before choosing your topic as there might not be much information on the mathematician you have chosen. Also, you should determine the topic early in the term so that you can "lock-in" your report topic!! The report must include: 1. The name of the mathematician. 2. The years the mathematician was alive. 3. A biography. 4. The mathematician's major contribution(s) to mathematics and an explanation of the importance. 5. A historical perspective during the time the mathematician was alive. Some suggestions on the historical perspective might be: (a) Any wars etc. (b) Scientific breakthroughs of the time (c) Major discoveries of the time (d) How did this mathematician change history etc.

The whole world reestablished this book starting with the Islamic translation on through time. THALES, FOUNDER OF GREEK GEOMETRY (585 B.C.E.) The birth of Greek astronomy has been attributed to Thales of Miletus. Thales brought from Egypt a number of fundamental geometric principles. Thales, an Ionian (western border of Asia Minor) who was active near the start of the sixth century bc has been credited with a number of geometric theorems. 1. A Circle is bisected by its diameter. 2. Angles at the base of any isosceles triangle are equal. 3. If two straight lines intersect the opposite angles formed are equal. 4. If two triangles have two angles and one side respectively equal, the triangles are equal in all respects. Thales was also well known for forecasting the solar eclipse, so he was also considered a scientist.

May Allah bless our Master Muhammad and his family and grant them peace. Fatwa and Qada' [sentence] in the Maliki School by Sidi Ali al-'Iraqi al-Husaini Preface I want to preface this study by explaining my reason for choosing this topic. The reason for my choice of this subject lies in the claim made by some ordinary people, and even some eminent thinkers, that holding to a specific school of fiqh leads to the rigidification of fiqh and closing the door of ijtihad . The legal and historical facts are very far from this claim, at least in respect of the application of the Maliki school by its scholars in the Maghrib and Andalusia. That is because the method on which they originated gave Maliki fiqh great flexibility and an extraordinary capacity for adaptation. This productive school has shown itself to be adaptable in different environments and times, right up to present times, by the virtue of the fact that the door of ijtihad in the School remains open right up until today. It is a definitive evidence which refutes the opinion of those who claim that holding to a school of fatwa and qada' (sentence) rigidifies fiqh and makes it capable of being adapted to different places and times.

Comme le nom l'indique, son arrière grand-père s'appelait Youness , son grand-père était Ahmad , et son père Abd al-Rahman . C'était une famille de savants, son père Abd al-Rahman était un historien. On sait peu de choses sur l'enfance de Ibn Youness mais on sait qu'il avait grandi dans une période d'une conquête militaire en Egypte. La dynastie Fatimite dirigeait un mouvement religieux et militaire pour conquérir toutes les régions Islamiques. Par conséquent ils avaient refuser de reconnaître les califes Abbasits . Les califes Fatimits avaient régné sur l'Afrique du Nord et la Sicile durant la première moitié du 10 ième siècle, mais après un nombre de vaines tentatives de vaincre l'Egypte, ils commencèrent une avance majeur dans le pays en 969 conquéraient la vallée du Nil. Ils fondèrent la ville du Caire comme la capitale de leur empire. Ibn Youness travaillait en étroite collaboration avec les Fatimits et deux Califes avaient soutenu son travail scientifique.

Abu'l-Hasan ibn Yunus Born: 950 in Egypt Died: 1009 in Fustat, Egypt Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Welcome page Yunus is famed for his astronomical observations and as an astrologer. He also produced many trigonometry tables, all designed for astronomical purposes. His major work, an astronomical handbook, was al-Zij al-Hakimi al-kabir. al-kabir means 'large' which is apt and al-Hakimi means that the work is dedicated to Caliph al-Hakim. The book is certainly large, containing 81 chapters. There are lists of observations made by Yunus and his predecessors. He describes 40 planetary conjunctions accurately and 30 lunar eclipses used by Simon Newcomb in his lunar theory. In addition there are planetary longitudes and calendar tables. Trigonometric functions are given as arcs rather than angles. Spherical trigonometry reaches a high level of sophistication in this work. Yunus was described by his biographer as follows:- He was an eccentric, careless and absent-minded man who dressed shabbily and had a comic appearance. Yunus predicted the date of his own death to be in seven days time when he was in good health. He tidied up his business affairs, locked himself in his house and recited the Koran until he died on the day he predicted.
