• Early medieval period (5th-10th centuries) characterized by limited mathematical advancements due to sociopolitical instability
• High medieval period (11th-13th centuries) witnessed a resurgence of interest in mathematics driven by translations of ancient texts and Islamic influences
• Late medieval period (14th-15th centuries) marked by the establishment of universities and the development of new mathematical concepts
• Key mathematical advancements include the introduction of Hindu-Arabic numerals, the development of algebra, and the application of mathematics to various fields (architecture, commerce, astronomy)
• Timeline of notable events:
  • 6th century: Boethius translates Greek mathematical texts into Latin
  • 9th century: Al-Khwarizmi writes "Al-Jabr" introducing algebra to the Islamic world
  • 12th century: Translations of Islamic mathematical texts into Latin begin

Mathematical Traditions in Early Medieval Europe

• Early medieval Europe relied heavily on Roman and Greek mathematical traditions preserved through Latin translations
• Boethius (c. 480-524) played a crucial role in translating Greek mathematical texts (Euclid's Elements, Nicomachus's Introduction to Arithmetic) into Latin
• Monasteries served as centers of learning and preservation of ancient mathematical knowledge during the early medieval period
• Computus, the calculation of the date of Easter, was a primary focus of mathematical study in early medieval Europe
  • Involved complex calculations based on lunar and solar cycles
  • Encouraged the development of astronomical and calendrical knowledge
• Abacus, a calculating tool, was widely used for arithmetic computations
  • Consisted of a board with columns representing different place values
  • Counters or beads were moved along the columns to perform calculations
• Geometry was primarily applied to surveying, architecture, and the construction of fortifications

Islamic Influence on European Mathematics

• Islamic civilization, particularly during the Golden Age (8th-13th centuries), made significant advancements in mathematics
• Translations of Greek mathematical texts into Arabic (Euclid's Elements, Ptolemy's Almagest) laid the foundation for further developments
• Al-Khwarizmi (c. 780-850) introduced algebra through his seminal work "Al-Jabr"
  • Systematized the solving of linear and quadratic equations
  • Introduced the concept of algorithmic problem-solving
• Hindu-Arabic numeral system, adopted by Islamic scholars, gradually replaced Roman numerals in Europe
  • Positional notation and the inclusion of zero revolutionized arithmetic calculations
• Islamic trigonometry, developed for astronomical purposes, introduced the sine function and improved upon Ptolemy's chord-based approach
• Transmission of Islamic mathematical knowledge to Europe occurred through various channels:
  • Translations of Arabic texts into Latin (Toledo, Sicily)
  • Scholarly exchanges in centers of learning (Cordoba, Palermo)
  • Trade and cultural contacts (Crusades, Reconquista)

The Role of Monasteries and Universities

• Monasteries served as centers of learning and scholarship throughout the medieval period
  • Monastic schools provided education in the liberal arts, including arithmetic and geometry
  • Scriptoria within monasteries produced and preserved mathematical manuscripts
• Cathedral schools emerged in the 11th century, offering advanced instruction in the quadrivium (arithmetic, geometry, music, astronomy)
• Universities, established in the 12th and 13th centuries, became hubs of mathematical learning and research
  • University of Bologna (1088) and University of Paris (c. 1150) were among the earliest
  • Curriculum included the quadrivium, with mathematics as a core subject
• Scholasticism, the dominant intellectual movement in medieval universities, emphasized logical reasoning and dialectical argumentation
  • Mathematical demonstrations and proofs gained importance
• Universities facilitated the dissemination of mathematical knowledge through the training of scholars and the circulation of texts
• Notable mathematical works studied in universities included Euclid's Elements, Boethius's De institutione arithmetica, and Sacrobosco's Tractatus de sphaera

Notable Mathematicians and Their Contributions

• Leonardo Fibonacci (c. 1170-1250)
  • Introduced Hindu-Arabic numerals to Europe through his book "Liber Abaci"
  • Developed the Fibonacci sequence and its applications to problem-solving
• Jordanus de Nemore (c. 1225-1260)
  • Wrote treatises on arithmetic, algebra, and mechanics
  • Developed a system of weights and measures based on the Roman pound
• Nicole Oresme (c. 1320-1382)
  • Pioneered graphical representations of functions and motion
  • Contributed to the development of coordinate geometry
• Thomas Bradwardine (c. 1300-1349)
  • Explored the concept of proportionality and its applications to physics
  • Developed the "Bradwardine function" relating velocity, force, and resistance
• Johannes Campanus (c. 1220-1296)
  • Produced an influential Latin translation of Euclid's Elements
  • Wrote commentaries on Euclid's work and Sacrobosco's Tractatus de sphaera
• Johannes Müller Regiomontanus (1436-1476)
  • Translated and published Greek mathematical texts (Archimedes, Apollonius)
  • Made significant contributions to trigonometry and astronomy

Mathematical Texts and Treatises

• Euclid's Elements, translated into Latin by Boethius and later by Campanus, served as the foundation for geometric study
• Boethius's De institutione arithmetica, a translation of Nicomachus's Introduction to Arithmetic, was a primary text for arithmetic education
• Al-Khwarizmi's Al-Jabr introduced algebra and algorithmic problem-solving to Europe through Latin translations
• Fibonacci's Liber Abaci popularized Hindu-Arabic numerals and their applications to commercial arithmetic
• Jordanus de Nemore's De elementis arithmetice artis and De numeris datis explored arithmetic and algebraic concepts

• Printing press, invented in the 15th century, facilitated the dissemination of mathematical knowledge and standardization of notation
• Algebraic symbolism, developed by Renaissance mathematicians (Viète, Descartes), built upon medieval algebraic concepts
• Coordinate geometry, pioneered by Descartes, had its roots in Oresme's graphical representations
• Trigonometry, advanced by Regiomontanus and others, paved the way for the development of infinitesimal calculus
• Mathematical education in universities continued to evolve, with a greater emphasis on practical applications and new discoveries
• Scientific societies (Royal Society, Académie des Sciences) emerged as centers of mathematical research and collaboration
• Contributions of medieval mathematicians were recognized and built upon by their Renaissance and early modern successors (Galileo, Kepler, Newton)
