Worksheet Number Fifteen Amicable Numbers and Thabit ibn Qurra We have seen the Pythagorean concepts of perfect and amicable numbers earlier in this course. The last theorem in book IX of Euclid, Theorem IX.36 states that if is a prime number then is a perfect number. Examples are 6, 28, 496 and 8,128. This is the pinnacle of ancient Greek number theory. The only amicable numbers known to the ancient Greeks were 220 and 284. To find some formula similar to the one in Euclid, but for amicable numbers, must occur to some students of number theory. A successful such mathematician was Thabit ibn Qurra , who grew up in Harran, in what is now Turkey, and lived from about 836 to 901. He ended up being the court astronomer in Baghdad. ThabitÕs theorem giving a formula to construct infinitely many pairs of amicable numbers is the following: Theorem and have the property that are prime numbers. Then a = and are amicable numbers, with a an abundant number and b a deficient number. An abundant number has the sum of its proper divisors bigger than the number, like 12. A deficient number has thee sum of its divisors smaller than the number, like 9.

Next: About this document Arab Contributions Within a century of Muhammad's conquest of Mecca, Islamic armies conquered lands from northern Africa, southern Europe, through the Middle East and east up to India. Within a century of that the Caliphate split up into several parts. The eastern segment, under the Abbasid caliphs, became a center of growth, of luxury, and of peace. In 766 the caliph al-Mansur founded his capitol in Baghdad and the caliph Harun al-Rashid, established a library. The stage was set for his successor, Al-Ma'mum. In the 9 century Al-Ma'mum established Baghdad as the new center of wisdom and learning. He establihed a research institute, the Bayt al-Hikma (House of Wisdom), which would last more than 200 years. Al-Ma'mum was responsible for a large scale translation project of as many ancient works as could be found. Greek manuscripts were obtained through treaties. By the end of the century, the major works of the Greeks had been translated. In addition, they learned the mathematics of the Babylonnians and the Hindus. What follows is a brief introduction to a few of the more prominent Arab mathematicians, and a sample of their work

Many of the people who joined these communities wanted to better educate themselves and their children, and they wanted to educate the outside world by their example. At the base of these communitarian ideals was a form of environmental determinism combined with the belief that people would choose to change to improve themselves, their children, and their environment. Members believed that intentional communities could provide a better life than could be achieved through private ownership and competition. Even with the high failure rate and the personal struggles involved, many communitarians continued to believe in cooperative lifestyles. Most of the early secular communities were democratic although not consensual; they aimed at equality and generally practiced it. Economically, most groups were communal, holding all property in common and distributing goods on the basis of need.

Nous remercions vivement M. Hourya Sinaceur qui nous a généreusement transmis son article sur l'infini mathématique paru dans le "Dictionnaire de Philosophie et d'Histoire des Sciences" et qui nous a accordé l'autorisation de le publier sur notre site. Infini mathématique La préhistoire L’infini offre peu de prise à l'expérience immédiate. Des myriades de brins d'herbe dans un pré, c'est un nombre très grand, mais pas infini. On trouverait une image plus suggestive dans les figures en abyme ou deux miroirs face à face. Mais même dans ces cas on poursuit en imagination un processus dont on ne perçoit effectivement que les premières étapes. L'infini cependant est présent dès qu'il y a mathématique. Les Grecs déjà l'avaient rencontré. Par exemple, Zénon d’Elée (V e siècle avant J. C) avec ses paradoxes sur la divisibilité à l’infini d’un segment de droite, les Pythagoriciens (VI e siècle avant J. C.) avec leur découverte de l’incommensurabilité de la diagonale du carré, Eudoxe (début du IV e siècle avant J. C) dont la théorie des proportions permet de traiter de tels incommensurables (livre V d’Euclide), Aristote (IV

935 B.C. At the age of twenty-seven, Ibrahim ibn Sinan, was the only known mathematician in the year 935 BC. He was born in the city of Baghdad in 908 BC, where he also died at the age of thirty-eight. Ibrahim ibn Sinan’s interests were in geometry, especially tangents to circles, astronomy, and mathematical philosophy. He also wrote several books on geometry, including On Drawing the Three Conic Sections , which explains the constructions of the ellipse, hyperbola, and parabola. By studying the geometry of the shadows of the sun, Sinan tried to describe what he thought was the motion of the sun. The most famous work of Ibrahim ibn Sinan was the quadrature of the parabola. From this problem, Sinan developed a method of integration that was more general than the previously defined technique by Archimedes. His book, On the Measurement of the Parabola , introduces a theorem that states that the area of a segment of a parabola is four-thirds times the area of the triangle inscribed in that parabola. Ibrahim ibn Sinan translated many Greek mathematical and philosophical works. Because of his work in mathematical philosophy, he has been labeled the "foremost Arab mathematician to treat mathematical philosophy." Author References: Ibrahim, ibn Sinan ibn Thabit ibn Qurra

93. The Mathematics Of Islam, Part 2 In this lecture, the topics consisted of alKhwarizmi (750-850), thabit ibnQurra (830-890), Abu-Sahl al-Kuhi (early 900s), ibn al-Haytham (965-1039 http://public.csusm.edu/public/DJBarskyWebs/330CollageOct01.html

The Mathematics of Islam, Part 2 The presentation given today by Dr. Barsky generated an overall theme that the works of the mathematicians of Islam during the period of (965-1039) seemed to show traces of calculus, despite the fact that calculus came about later in time. In this lecture, the topics consisted of al-Khwarizmi (750-850), Thabit ibn Qurra (830-890), Abu-Sahl al-Kuhi (early 900s), ibn al-Haytham (965-1039), Mohammed's Flight from Mecca (622), the Battle of Tours (732), the period of Caliphates, the Fall of Baghdad to Seljuk Turks (1055), the beginning of the first Crusade (1096), the arrival of the Mongols under Ghengis Khan (early 1200s), al-Khwarizmi's truncated pyramid problem, Mishnat ha-Middot, and ibn al-Haytham's volume of a paraboloid calculations. We did not have a mathematician of the day, instead we talked about our papers that will be due October 8. We then covered more of the history of Islamic mathematics. We focused on al-Khwarizmi (750-850), Thabit ibn Qurra (830-890), Abu-Sahl al-Kuhi (early 900s), and ibn al-Haytham (965-1039). We concentrated on problems from al-Khwarizmi and ibn al-Haytham, which mainly dealt with finding volumes. I really enjoyed the lecture about the volume of a parabola from ibn al-Haytham. I have previously seen the symbol for (the sum of), but I usually stopped at that point because I did not understand, or I felt like it was too complicated. I understand the logic behind finding the circumscribed volume, and inscribed volume of the parabola. I can see that the difference between the two is the volume of the bottom disk of the circumscribed volume. I see that the (sum symbol) is included in equations that are interested in finding the sum of the differences between two estimates which will give you the solution to a problem. I also see that as you take the sum of the differences you are reaching the limit which is related to the volume of the parabola.

Teorema de Pitágoras E n un triángulo rectángulo, la suma de los cuadrados de los catetos (b y c) es igual al cuadrado de la hipotenusa (a): a =b +c Los números a b y c que verifican esta relación se llaman ternas pitagóricas o números pitagóricos en alusión al estudio que de ellos hicieron Pitágoras y sus discípulos. Los antecedentes históricos de este teorema se remontan a las civilizaciones babilónica y egipcia en el segundo milenio a.J.C. El papiro Rhind y el de Moscú confirman la existencia de tablas de número pitagóricos en esa época. Tras las inundaciones del Nilo, los agrimensores egipcios construían triángulos rectángulos de catetos 3 y 4 y de hipotenusa 5, mediante una cuerda de 12 nudos para parcelar el terreno. Euclides demuestra el Teorema de Pitágoras en la proposición 47 del Libro I de los Elementos En los triángulos rectángulos el cuadrado sobre el ángulo opuesto al ángulo recto es equivalente a los cuadrados sobre los lados que forman el ángulo recto En la proposición 48 demuestra que si el cuadrado construido sobre uno de los lados de un triángulo es equivalente a los cuadrados, juntos, de los otros dos lados, el ángulo formado por esos dos lados es recto, es decir, el recíproco de la Proposición 47.
