sounds a bit like make believe: no trace remains of this ancient library, destroyed in the 13th Century, so we cannot be sure exactly where it was located or what it looked like.<\/p>\n<p>But this prestigious academy was in fact a major intellectual powerhouse in Baghdad during the Islamic Golden Age, and the birthplace of mathematical concepts as transformative as the common zero and our modern-day \u201cArabic\u201d numerals.<\/p>\n<p>Founded as a private collection for caliph Harun Al-Rashid in the late 8th Century then converted to a public academy some 30 years later, the House of Wisdom appears to have pulled scientists from all over the world towards Baghdad, drawn as they were by the city\u2019s vibrant intellectual curiosity and freedom of expression (Muslim, Jewish and Christian scholars were all allowed to study there).<\/p>\n<p>An archive as formidable in size as the present-day British Library in London or the Biblioth\u00e8que Nationale of Paris, the House of Wisdom eventually became an unrivalled centre for the study of humanities and sciences, including mathematics, astronomy, medicine, chemistry, geography, philosophy, literature and the arts \u2013 as well as some more dubious subjects such as alchemy and astrology.<\/p>\n<p><em>You might also like:<\/em><\/p>\n<ul>\n<li><a

the academy ushered in a cultural Renaissance that would entirely alter the course of mathematics.<\/p>\n<p>The House of Wisdom was destroyed in the Mongol Siege of Baghdad in 1258 (according to legend, so many manuscripts were tossed into the River Tigris that its waters turned black from ink), but the discoveries made there introduced a powerful, abstract mathematical language that would later be adopted by the Islamic empire, Europe, and ultimately, the entire world.<\/p>\n<p>*****<\/p>\n<p>\u201cWhat should matter to us is not the precise details of where or when the House of Wisdom was created,\u201d says Jim Al-Khalili, a professor of physics at the University of Surrey. \u201cFar more interesting is the history of the scientific ideas themselves, and how they developed as a result of it.\u201d<\/p>\n<p>Tracing the House of Wisdom\u2019s mathematical legacy involves a bit of time travel back to the future, as it were. For hundreds of years until the ebb of the Italian Renaissance, one name was synonymous with mathematics in Europe: Leonardo da Pisa, known posthumously as Fibonacci.\u00a0Born in Pisa in 1170, the Italian mathematician received his primary instruction in Bugia, a trading enclave located on the Barbary coast of Africa (coastal North Africa). In his early 20s, Fibonacci traveled to the Middle East, captivated by ideas that had come west from India through Persia. When he returned to Italy, Fibonacci published\u00a0<a href=\"https:\/\/www.britannica.com\/topic\/Liber-abaci\">Liber Abbaci,<\/a> one of the first Western works to describe the Hindu-Arabic numeric system.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"article-body-native-ad article-body__body-text\">\n<div class=\"\">\n<div class=\"article-body__image-text article-body__image-text--portrait\">\n<div>\n<picture><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1024x1280\/p090d8hr.webp\" type=\"image\/webp\" media=\"(min-width:624px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1024x1280\/p090d8hr.jpg\" type=\"image\/jpeg\" media=\"(min-width:624px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/885x1280\/p090d8hr.webp\" type=\"image\/webp\" media=\"(min-width:485px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/885x1280\/p090d8hr.jpg\" type=\"image\/jpeg\" media=\"(min-width:485px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/720x900\/p090d8hr.webp\" type=\"image\/webp\" media=\"(min-width:320px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/720x900\/p090d8hr.jpg\" type=\"image\/jpeg\" media=\"(min-width:320px)\" \/><img decoding=\"async\" id=\"\" title=\"Fibonacci traveled to the Middle East, captivated by ideas that had travelled west along trading routes (Credit: Laura Lezza\/Getty Images)\" draggable=\"false\" src=\"https:\/\/ychef.files.bbci.co.uk\/720x900\/p090d8hr.jpg\" alt=\"Fibonacci traveled to the Middle East, captivated by ideas that had travelled west along trading routes (Credit: Laura Lezza\/Getty Images)\" \/><\/picture>\n<div class=\"inline-image__description b-reith-sans-font inline-image__description--desktop\">\n<div class=\"text-summary\">\n<p class=\"text-summary__text text-summary__text--grey text-summary__text--left\">Fibonacci traveled to the Middle East, captivated by ideas that had travelled west along trading routes (Credit: Laura Lezza\/Getty Images)<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"body-text-card b-font-family-serif\">\n<div class=\"body-text-card__text body-text-card__text--future body-text-card__text--flush-text\">\n<div>\n<p>When\u00a0Liber Abbaci first appeared in 1202,\u00a0Hindu-Arabic numerals\u00a0were known to only a few\u00a0intellectuals; European tradesmen and scholars were still clinging to Roman numerals, which made multiplication and division extremely cumbersome (try multiplying MXCI by LVII!). Fibonacci\u2019s book demonstrated numerals\u2019 use in arithmetic operations \u2013 techniques which could be applied to practical problems like profit margin, money changing, weight conversion, barter and interest.<\/p>\n<p>\u201cThose who wish to know the art of calculating, its subtleties and ingenuities, must know computing with hand figures,\u201d Fibonacci wrote in the first chapter of his encyclopedic work, referring to the digits that children now learn in school. \u201cWith these nine figures and the sign 0, called zephyr, any number whatsoever is written.\u201d Suddenly, mathematics was available to all in a useable form.<\/p>\n<p>Fibonacci\u2019s great genius was not just his creativity as a mathematician, however, but his keen understanding of the advantages known to Muslim scientists for centuries: their calculating formulas, their decimal place system, their algebra. In fact, Liber Abbaci relied almost exclusively on\u00a0the algorithms of 9th-Century mathematician Al-Khwarizmi. His revolutionary <a href=\"https:\/\/www.wdl.org\/en\/item\/7462\/\">treatise<\/a> presented, for the first time, a systematic way of solving quadratic equations. Because of his discoveries in the field, Al-Khwarizmi is often referred to as the father of\u00a0algebra \u2013 a word we owe to him, from the Arabic <em>al-jabr<\/em>, \u201cthe restoring of broken parts\u201d\u2014and in 821 he was appointed astronomer and head librarian of the House of Wisdom.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"body-text-card b-font-family-serif\">\n<div class=\"body-text-card__text body-text-card__text--future body-text-card__text--flush-text\">\n<div>\n<p>Al-Khwarizmi\u2019s treatise introduced the Muslim world to the decimal number system,\u201d explains Al-Khalili. \u201cOthers, such as Leonardo da Pisa, helped transmit it across Europe.\u201d<\/p>\n<p>Fibonacci\u2019s transformative influence on modern maths was thus a legacy owed in great part to Al-Khwarizmi. And so two men separated by nearly four centuries were connected by an ancient library: the most celebrated mathematician of the Middle Ages stood on the shoulder of another pioneering thinker, one whose breakthroughs were made at an iconic institution of the Islamic Golden Age.<\/p>\n<p>Perhaps because so little is known about the House of Wisdom, historians are occasionally tempted to exaggerate its scope and purpose, giving it an mythic status somewhat at odds with the scant historical records left to us. \u201cSome argue that the House of Wisdom was nothing like as grand as it became in the eyes of many,\u201d says Al-Khalili. \u201cBut its association with men such as Al-Khwarizmi, with his work in mathematics, astronomy and geography, is for me strong evidence that the House of Wisdom was closer to a true academy, not just a repository of translated books.\u201d<\/p>\n<p>Scholars and translators at the library also took great pains to ensure that their work was accessible to the reading public. \u201cThe House of Wisdom is fundamentally important, as it\u2019s through translations there \u2013 Arabic scholars who translated Greek ideas into the vernacular \u2013 that we formed the bedrock of our mathematical understanding\u201d says June Barrow-Green, professor of history of mathematics at the Open University in the UK. The palace library was as much a window into numerical ideas from the past as it was a site of scientific innovation.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"article-body__image-text article-body__image-text--landscape\">\n<div>\n<picture><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1600x900\/p090d86s.webp\" type=\"image\/webp\" media=\"(min-width:1200px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1600x900\/p090d86s.jpg\" type=\"image\/jpeg\" media=\"(min-width:1200px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1280x720\/p090d86s.webp\" type=\"image\/webp\" media=\"(min-width:880px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/1280x720\/p090d86s.jpg\" type=\"image\/jpeg\" media=\"(min-width:880px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/976x549\/p090d86s.webp\" type=\"image\/webp\" media=\"(min-width:576px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/976x549\/p090d86s.jpg\" type=\"image\/jpeg\" media=\"(min-width:576px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/624x351\/p090d86s.webp\" type=\"image\/webp\" media=\"(min-width:224px)\" \/><source srcset=\"https:\/\/ychef.files.bbci.co.uk\/624x351\/p090d86s.jpg\" type=\"image\/jpeg\" media=\"(min-width:224px)\" \/><img decoding=\"async\" id=\"\" title=\"The Fibonacci sequence can even be found in nature, such as in the design of nautilus shells (Credit: Reinhard Dirscherl\/ullstein bild via Getty Images)\" draggable=\"false\" src=\"https:\/\/ychef.files.bbci.co.uk\/976x549\/p090d86s.jpg\" alt=\"The Fibonacci sequence can even be found in nature, such as in the design of nautilus shells (Credit: Reinhard Dirscherl\/ullstein bild via Getty Images)\" \/><\/picture>\n<div class=\"inline-image__description b-reith-sans-font inline-image__description--desktop\">\n<div class=\"text-summary\">\n<p class=\"text-summary__text text-summary__text--grey text-summary__text--left\">The Fibonacci sequence can even be found in nature, such as in the design of nautilus shells (Credit: Reinhard Dirscherl\/ullstein bild via Getty Images)<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"body-text-card b-font-family-serif\">\n<div class=\"body-text-card__text body-text-card__text--future body-text-card__text--flush-text\">\n<div>\n<p>Long before our current decimal system, the binary number system that programs our computers, before Roman numerals, before the system used by ancient Mesopotamians, humans were using early tally systems to record calculations. While we might find each of these imponderable or antiquated, differing numerical representations can actually teach us something valuable about structure, relationships, and the historical and cultural contexts from which they emerged.<\/p>\n<p>They reinforce the idea of place value and abstraction, helping us to better understand how numbers work. They show that \u201cthe Western way wasn\u2019t the only way\u201d, says Barrow-Green. \u201cThere is a real value in understanding different numbers systems.\u201d<\/p>\n<p>When an ancient trader wanted to write \u201ctwo sheep\u201d, for example, she could inscribe in clay a picture of two sheep. But this would be impractical if she wanted to write \u201c20 sheep.\u201d Sign-value notation is a system in which numeric symbols add together signify a value; in this case, drawing two sheep to represent the actual quantity.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<div class=\"body-text-card b-font-family-serif\">\n<div class=\"body-text-card__text body-text-card__text--future body-text-card__text--flush-text\">\n<div>\n<p>A vestige of sign-value notation, Roman numerals somehow persisted despite the introduction of Al-Khwarizmi\u2019s system, which relied on the position of digits to represent quantities. Like the towering monuments on which they were inscribed, Roman numerals outlived the empire that gave birth to them \u2013 whether by accident, sentiment or purpose, none can say for sure.<\/p>\n<p>This year marks the 850th\u00a0anniversary of Fibonacci\u2019s birth. It could also be the moment\u00a0which threatens to undo the journeywork of Roman numerals. In the UK, traditional time-pieces have been replaced\u00a0with easier-to-read digital clocks in school classrooms, <a href=\"https:\/\/www.washingtonpost.com\/news\/answer-sheet\/wp\/2018\/05\/02\/british-schools-are-replacing-analog-clocks-with-digital-ones-to-help-clueless-students\/\">for fear students can no longer tell analogue time properly<\/a>.

A former maths teacher, Rycroft-Smith is now a leading voice in mathematics education, and studies differences across global curricula. While Wales, Scotland and Ireland do not include Roman numerals in their learning objectives, and the US has no standard requirements, England explicitly states that students must be able to read Roman numerals up to 100.<\/p>\n<p>Many of us will find nothing special about the figure MMXX (that\u2019s 2020, if you\u2019re unaware).
