History of Algebra and Its Implications for Teaching
Maggio: History of Algebra and its Implications for Teaching History of Algebra and its Implications for Teaching Jaime Maggio Fall 2020 MA 398 Senior Seminar Mentor: Dr.Loth Published by DigitalCommons@SHU, 2021 1 Academic Festival, Event 31 [2021] Abstract Algebra can be described as a branch of mathematics concerned with finding the values of unknown quantities (letters and other general sym- bols) defined by the equations that they satisfy. Algebraic problems have survived in mathematical writings of the Egyptians and Babylonians. The ancient Greeks also contributed to the development of algebraic concepts. In this paper, we will discuss historically famous mathematicians from all over the world along with their key mathematical contributions. Mathe- matical proofs of ancient and modern discoveries will be presented. We will then consider the impacts of incorporating history into the teaching of mathematics courses as an educational technique. 1 https://digitalcommons.sacredheart.edu/acadfest/2021/all/31 2 Maggio: History of Algebra and its Implications for Teaching 1 Introduction In order to understand the way algebra is the way it is today, it is important to understand how it came about starting with its ancient origins. In a mod- ern sense, algebra can be described as a branch of mathematics concerned with finding the values of unknown quantities defined by the equations that they sat- isfy. Algebraic problems have survived in mathematical writings of the Egyp- tians and Babylonians. The ancient Greeks also contributed to the development of algebraic concepts, but these concepts had a heavier focus on geometry [1]. The combination of all of the discoveries of these great mathematicians shaped the way algebra is taught today. -
Arithmetical Proofs in Arabic Algebra Jeffery A
This article is published in: Ezzaim Laabid, ed., Actes du 12è Colloque Maghrébin sur l'Histoire des Mathématiques Arabes: Marrakech, 26-27-28 mai 2016. Marrakech: École Normale Supérieure 2018, pp 215-238. Arithmetical proofs in Arabic algebra Jeffery A. Oaks1 1. Introduction Much attention has been paid by historians of Arabic mathematics to the proofs by geometry of the rules for solving quadratic equations. The earliest Arabic books on algebra give geometric proofs, and many later algebraists introduced innovations and variations on them. The most cited authors in this story are al-Khwārizmī, Ibn Turk, Abū Kāmil, Thābit ibn Qurra, al-Karajī, al- Samawʾal, al-Khayyām, and Sharaf al-Dīn al-Ṭūsī.2 What we lack in the literature are discussions, or even an acknowledgement, of the shift in some authors beginning in the eleventh century to give these rules some kind of foundation in arithmetic. Al-Karajī is the earliest known algebraist to move away from geometric proof, and later we see arithmetical arguments justifying the rules for solving equations in Ibn al-Yāsamīn, Ibn al-Bannāʾ, Ibn al-Hāʾim, and al-Fārisī. In this article I review the arithmetical proofs of these five authors. There were certainly other algebraists who took a numerical approach to proving the rules of algebra, and hopefully this article will motivate others to add to the discussion. To remind readers, the powers of the unknown in Arabic algebra were given individual names. The first degree unknown, akin to our �, was called a shayʾ (thing) or jidhr (root), the second degree unknown (like our �") was called a māl (sum of money),3 and the third degree unknown (like our �#) was named a kaʿb (cube). -
The Persian-Toledan Astronomical Connection and the European Renaissance
Academia Europaea 19th Annual Conference in cooperation with: Sociedad Estatal de Conmemoraciones Culturales, Ministerio de Cultura (Spain) “The Dialogue of Three Cultures and our European Heritage” (Toledo Crucible of the Culture and the Dawn of the Renaissance) 2 - 5 September 2007, Toledo, Spain Chair, Organizing Committee: Prof. Manuel G. Velarde The Persian-Toledan Astronomical Connection and the European Renaissance M. Heydari-Malayeri Paris Observatory Summary This paper aims at presenting a brief overview of astronomical exchanges between the Eastern and Western parts of the Islamic world from the 8th to 14th century. These cultural interactions were in fact vaster involving Persian, Indian, Greek, and Chinese traditions. I will particularly focus on some interesting relations between the Persian astronomical heritage and the Andalusian (Spanish) achievements in that period. After a brief introduction dealing mainly with a couple of terminological remarks, I will present a glimpse of the historical context in which Muslim science developed. In Section 3, the origins of Muslim astronomy will be briefly examined. Section 4 will be concerned with Khwârizmi, the Persian astronomer/mathematician who wrote the first major astronomical work in the Muslim world. His influence on later Andalusian astronomy will be looked into in Section 5. Andalusian astronomy flourished in the 11th century, as will be studied in Section 6. Among its major achievements were the Toledan Tables and the Alfonsine Tables, which will be presented in Section 7. The Tables had a major position in European astronomy until the advent of Copernicus in the 16th century. Since Ptolemy’s models were not satisfactory, Muslim astronomers tried to improve them, as we will see in Section 8. -

A history of algebra from antiquity to the early twentieth century, by Victor J. Katz and Karen Hunger Parshall, Princeton University Press, Princeton and Oxford, 2014, xvi+485 pp., ISBN 978-0-691-14905-9, US $49.50 1. Algebra now Algebra has been a part of mathematics since ancient times, but only in the 20th century did it come to play a crucial role in other areas of mathematics. Algebraic number theory, algebraic geometry, and algebraic topology now cast a big shadow on their parent disciplines of number theory, geometry, and topology. And algebraic topology gave birth to category theory, the algebraic view of mathematics that is now a dominant way of thinking in almost all areas. Even analysis, in some ways the antithesis of algebra, has been affected. As long ago as 1882, algebra captured some important territory from analysis when Dedekind and Weber absorbed the Abel and Riemann–Roch theorems into their theory of algebraic function fields, now part of the foundations of algebraic geometry. Not all mathematicians are happy with these developments. In a speech in 2000, entitled Mathematics in the 20th Century, Michael Atiyah said: Algebra is the offer made by the devil to the mathematician. The devil says “I will give you this powerful machine, and it will answer any question you like. All you need to do is give me your soul; give up geometry and you will have this marvellous machine.” Atiyah (2001), p. -
Homotecia Nº 3-10 Marzo 2012
HOMOTECIA Nº 3 – Año 10 Jueves, 1º de Marzo de 2012 1 Futbol. Seguridad personal. Maltrato Infantil. “Dominó”. Violencia. Este editorial no se hubiera escrito si cuatro noticias que se sucedieron recientemente no hubiesen superado nuestra capacidad de asombro, la cual suponíamos agotada desde hace tiempo. Más que sorprendernos, nos impactaron. Nos hemos de referir a ellas sin seguir el orden cronológico en el cual se sucedieron. Lo cierto está en que cualquier hecho violento puede tener explicación pero en ningún caso justificación. La primera noticia provino de Egipto, haciendo referencia al insólito hecho que después de culminado el partido entre los equipos rivales, los fanáticos del equipo local arremetieron con saña contra los fanáticos del equipo visitante, provocando la muerte de por lo menos setenta personas e hiriendo a más de doscientas. Ya es CLAUDE E. SHANNON costumbre que en un número significativo de los estadios del mundo donde se practica el futbol ocurran (1916-2001) hechos violentos a causa de las divergencias por las preferencias “deportivas” y la defensa a ultranza de "El padre de la teoría de la información" los colores de la divisa admirada, pero en ningún caso llegar a la bestial conducta de acabar con la vida de los semejantes. Y aquí no caben las explicaciones que indicamos al principio del escrito porque el Nació 30 Abril 1916 en Gaylord, Michigan, y equipo del cual eran fanáticos los furibundos agresores ganó el partido. Pensamos: ¿Qué hubiese falleció 24 Febrero de 2001 en Medford, ocurrido si perdía? Aquí no vale ni suspensión del campeonato de liga ni suspensión de por vida del Massachusetts, ambos eventos en Estados Unidos. -
Early History of Algebra: a Sketch
Math 160, Fall 2005 Professor Mariusz Wodzicki Early History of Algebra: a Sketch Mariusz Wodzicki Algebra has its roots in the theory of quadratic equations which obtained its original and quite full development in ancient Akkad (Mesopotamia) at least 3800 years ago. In Antiq- uity, this earliest Algebra greatly influenced Greeks1 and, later, Hindus. Its name, however, is of Arabic origin. It attests to the popularity in Europe of High Middle Ages of Liber al- gebre et almuchabole — the Latin translation of the short treatise on the subject of solving quadratic equations: Q Ì Al-kitabu¯ ’l-muhtas.aru f¯ı é ÊK.A®ÜÏ@ð .m. '@H . Ak ú¯ QåJjÜÏ@ H. AJº Ë@ – h. isabi¯ ’l-gabriˇ wa-’l-muqabalati¯ (A summary of the calculus of gebr and muqabala). The original was composed circa AD 830 in Arabic at the House of Wisdom—a kind of academy in Baghdad where in IX-th century a number of books were compiled or translated into Arabic chiefly from Greek and Syriac sources—by some Al-Khwarizmi2 whose name simply means that he was a native of the ancient city of Khorezm (modern Uzbekistan). Three Latin translations of his work are known: by Robert of Chester (executed in Segovia in 1140), by Gherardo da Cremona3 (Toledo, ca. 1170) and by Guglielmo de Lunis (ca. 1250). Al-Khwarizmi’s name lives today in the word algorithm as a monument to the popularity of his other work, on Indian Arithmetic, which circulated in Europe in several Latin versions dating from before 1143, and spawned a number of so called algorismus treatises in XIII-th and XIV-th Centuries. -
Notes for a History of the Teaching of Algebra 1
Notes for a History of the Teaching of Algebra 1 João Pedro da Ponte Instituto de Educação da Universidade de Lisboa Henrique Manuel Guimarães Instituto de Educação da Universidade de Lisboa Introduction Abundant literature is available on the history of algebra. However, the history of the teaching of algebra is largely unwritten, and as such, this chapter essentially con- stitutes some notes that are intended to be useful for future research on this subject. As well as the scarcity of the works published on the topic, there is the added difficulty of drawing the line between the teaching of algebra and the teaching of arithmetic—two branches of knowledge whose borders have varied over time (today one can consider the arithmetic with the four operations and their algorithms and properties taught in schools as nothing more than a small chapter of algebra). As such, we will be very brief in talking about the more distant epochs, from which we have some mathematics docu- ments but little information on how they were used in teaching. We aim to be more ex- plicit as we travel forwards into the different epochs until modern times. We finish, nat- urally, with some reflections on the present-day and future situation regarding the teach- ing of algebra. From Antiquity to the Renaissance: The oral tradition in algebra teaching In the period from Antiquity to the Renaissance, algebra was transmitted essen- tially through oral methods. The written records, such as clay tablets and papyri, were used to support oral teaching but duplication was expensive and time-consuming. -
Islamic Mathematics
Islamic Mathematics Elizabeth Rogers MATH 390: Islamic Mathematics Supervised by Professor George Francis University of Illinois at Urbana-Champaign August 2008 1 0.1 Abstract This project will provide a summary of the transmission of Greek mathe- matics through the Islamic world, the resulting development of algebra by Muhammad ibn Musa al-Khwarizmi, and the applications of Islamic algebra in modern mathematics through the formulation of the Fundamental Theo- rem of Algebra. In addition to this, I will attempt to address several cultural issues surrounding the development of algebra by Persian mathematicians and the transmission of Greek mathematics through Islamic mathematicians. These cultural issues include the following questions: Why was the geometry of Euclid transmitted verbatim while algebra was created and innovated by Muslim mathematicians? Why didn't the Persian mathematicians expand or invent new theorems or proofs, though they preserved the definition-theorem-proof model for ge- ometry? In addition, why did the definition-theorem-proof model not carry over from Greek mathematics (such as geometry) to algebra? Why were most of the leading mathematicians, in this time period, Mus- lim? In addition, why were there no Jewish mathematicians until recently? Why were there no Orthodox or Arab Christian mathematicians? 0.2 Arabic Names and Transliteration Arabic names are probably unfamiliar to many readers, so a note on how to read Arabic names may be helpful. A child of a Muslim family usually receives a first name ('ism), followed by the phrase \son of ··· "(ibn ··· ). For example, Th¯abitibn Qurra is Th¯abit,son of Qurra. Genealogies can be combined; for example, Ibr¯ah¯ımibn Sin¯anibn Th¯abitibn Qurra means that Ibr¯ah¯ımis the son of Sin¯an,grandson of Th¯abit,and great-grandson of Qurra. -
Roman Duda (Wrocław, Poland) EMIGRATION OF
ORGANON 44:2012 Roman Duda (Wrocław, Poland) EMIGRATION OF MATHEMATICIANS FROM POLAND IN THE 20 th CENTURY (ROUGHLY 1919–1989) ∗ 1. Periodization For 123 years (1795–1918) Poland did not exist as an independent state, its territory being partitioned between Prussia (Germany), Austria and Russia 1. It was a period of enforced assimilation within new borders and thus of restraining native language and culture which first provoked several national uprisings against oppressors, and then – in the three decades at the turn of the 19 th to 20 th centuries – of a slow rebuilding of the nation’s intellectual life. Conditions, however, were in general so unfavourable that many talents remained undeveloped while some talented people left the country to settle and work elsewhere. Some of the mathematicians emigrating then (in the chronological order of birth): • Józef Maria Hoene–Wro ński (1776–1853) in France, • Henryk Niew ęgłowski (1807–1881) in Paris, • Edward Habich (1835–1909) in Peru, • Franciszek Mertens (1840–1929) in Austria, • Julian Sochocki (1842–1927) in Petersburg, • Jan Ptaszycki (1854–1912) in Petersburg, • Bolesław Młodziejewski (1858–1923) in Moscow, • Cezary Russyan (1867–1934) in Kharkov, • Władysław Bortkiewicz (1868–1931) in Berlin, • Alexander Axer (1880–1948) in Switzerland. Thus the period of partitions was a time of a steady outflow of many good names (not only mathematicians), barely balanced by an inflow due to assim- ilation processes. The net result was decisively negative. After Poland regained independence in 1918, five newly established or re–established Polish universities (Kraków, Lwów, Warsaw, Vilnius, Pozna ń) ∗ The article has been prepared on the suggestion of Prof. -
