22. Medieval Mathematics Two Figures From The Later Middle Ages On the other hand, there is a strong likelihood that the works of another author,jordanus nemorarius, on the Hindu numerals were being utilized for http://www.math.rutgers.edu/~cherlin/History/Papers2002/medieval.html

Medieval Mathematics: Two Figures from the Later Middle Ages Teresa Kuo Demonstratio de algorismo , which details the Arabic number system and its use of integers. Other treatises include the Demonstratio de minutiis, which covered fractions, and the Liber phylotegni de triangulis, wh ich highlighted geometric proofs [4, p. I182]. His work De numeris datis Let the given number be abc and let it be divided into two parts ab and c, and let d be the given product of the parts ab and c. Let the square of ab be e and let four times d be f, and let g be the result of taking f from e. Then g is the square of the difference between ab and c. Let h be the square root of g. Then h is the difference between ab and c. Since h is known, c and ab are determined [1, p. 284]. Nemorarius, unlike Euclid however, did not state that the variables were to be regarded as being line segments, but this was inferred. A different medieval mathematician credited with using Hindu-Arabic numerals was Leonardo de Pisa, a contemporary of Ne morarius. Leonardo de Pisa, (ca. 1180-1250), was born in Pisa (now part of Italy) and was the son of Guglielmo Bonaccio (from "Fibonacci", or "son of Bonaccio", is derived). This, and most information concerning the life of Fibonacci comes from an autobiographical passage in the beginning of the one of his works, the Liber Abbaci (a2 + b2)(c2+d2) = (ac + bd)2 + (bc - ad)2 = (ad + bc)2 + (ac - bd)2

Earliest Uses of Symbols for Variables Last revision: Dec. 24, 2001 Greek letters. The use of letters to represent general numbers goes back to Greek antiquity. Aristotle frequently used single capital letters or two letters for the designation of magnitude or number (Cajori vol. 2, page 1). Diophantus (fl. about 250-275) used a Greek letter with an accent to represent an unknown. G. H. F. Nesselmann takes this symbol to be the final sigma and remarks that probably its selection was prompted by the fact that it was the only letter in the Greek alphabet which was not used in writing numbers. However, differing opinions exist (Cajori vol. 1, page 71). In 1463, Benedetto of Florence used the Greek letter rho for an unknown in Trattato di praticha d'arismetrica. (Franci and Rigatelli, p. 314) Roman letters. In Leonardo of Pisa's Liber abbaci (1202) the representation of given numbers by small letters is found. The Boncompagni edition, page 455, has: diuidatur aliquis numerus .a. in duas partes, que sint .b.g.; et diuidatur .a. per .b., et ueniet .e.; et .a. per .g. ueniet .d.: dico quod multiplicatio .d. in .e.est sicut agregatio .d.cum .e. [divide some number .a. in two parts which are .b.g.; and divide .a. by .b. to obtain .e.; and .a. by .g. to obtain .d.: I say that the product of .d. in .e. is as the sum of .d. with .e.] The dots were used to bring into prominence letters occurring in the running text, a practice common in manuscripts of that time [Barnabas Hughes; Cajori vol. 2, page 2].

24. First Scottish Books (Chepman & Myller Prints) - Digital Library - NLS the clearest example is provided by David Lauxius of Edinburgh, who was named asa press corrector in the colophon of jordanus nemorarius, Arithmetica, printed http://www.nls.uk/digitallibrary/chepman/history.htm

When Walter Chepman and Androw Myllar set up the first Scottish press in 1508, over fifty years had passed since printing with moveable types was first carried out in Germany (the completion of the Gutenberg Bible dates from late 1454 or 1455), whence it spread to other countries in mainland Europe, and then to England, where William Caxton, who had earlier done some printing in Cologne and Bruges, set up his press in Westminster in 1476. Therefore over thirty years separated the beginning of printing in Scotland from its beginning in England, and then the know-how spread from France and not England. But between the 1450s and 1508 Scots were not strangers to books and their printing, and it was largely the close relations between France and Scotland which were responsible for this. Many Scots went to France or occasionally elsewhere in mainland Europe for their higher education, and they brought back printed books. Some of them also had their work published on the Continent: for example, the two undated books by the Aberdonian philosopher James Liddell, Ars obligatoria logicalis and Tractatus conceptuum et signorum Arithmetica , printed in Paris in 1496. It was in this tradition that, in 1505 and 1506, Androw Myllar had two books (one with his windmill device) printed for him in Rouen.

L'élaboration des nouvelles sciences et des nouvelles techniques comportait la mise en valeur de plusieurs aspects mathématiques de l'activité humaine, tels que la mesure des qualités et la définition des positions.

Next: About this document Mideval Europe century The Europeans learned Arabic in the 12 century. All mathematics and astronomy was written in Arabic. By the end of the 12 century the best mathematics was done in Christian Italy. During this century there was a spate of translations of Arabic works to Latin. Later Example. Elements in Arabic Latin in 1142 by Adelard of Bath (ca. 1075-1160). He also translated Al-Khwarizmi's astronomical tables (Arabic Latin) in 1126 and in 1155 translated Ptolemy's Almgest (Greek Latin) (The world background at this time was the crusades.) Gherard of Cremona Born: 1114 in Cremona, Italy Died: 1187 in Toledo, Spain Gherard's name is sometimes written as Gerard. He went to Toledo, Spain to learn Arabic so he could read Ptolemy's Almagest since no Latin translations existed at that time. He remained there for the rest of his life. Gherard made translations of Ptolemy (1175) and of Euclid from Arabic. Some of these translations from Arabic became more popular than the (often earlier) translations from Greek. In making translations of other Arabic work he translated the Arabic word for sine into the Latin sinus, from where our

Den salige Jordan av Sachsen (~1195-1237) Minnedag: 15. februar Den salige Jordan av Sachsen ble født ca 1195 (ca 1177?) i Sachsen i Tyskland. Han fikk navnet Gordanus eller Giordanus. Til tross for at det finnes et relativt rikholdig biografiske materiale om ham, nevnes aldri hvor gammel han var da han døde, selv om han beskrives som «en gammel mann». Dette antyder minst 60 år, noe som betyr at han ikke kan ha vært født senere enn 1677. Helligkåringskongregasjonens Index ac status causarum skriver imidlertid at han ble født ca 1195. Bollandistene, som baserer seg på ordenens krøniker, skriver at han ble født på slottet «Borcberg», (Borgberge, Burgberg, Borgentreich) ved Paderborn, mens andre foreslår Padberg nær Westfalen. Vi vet ingen ting om hans barndom, bortsett fra at han kom fra en fornem familie. Han studerte i Paris, hvor han kan ha levd i relativ velstand i den nasjonale «skolen» med lærere og andre studenter fra Tyskland. Han studerte de tradisjonelle sju «frie kunster», først trivium -grammatikk, retorikk og dialektikk, og deretter
