42. Earliest Uses Of Grouping Symbols use of the vinculum above the parts affected was by frans van schooten (c . In van schooten s 1646 edition of Vieta, is used to represent B(D2 + BD). http://members.aol.com/jeff570/grouping.html

Earliest Uses of Grouping Symbols Last revision: June 24, 1999 Vinculum below. The first use of the vinculum was in 1484 by Nicolas Chuquet (1445?-1500?) in his Le Triparty en la Science des Nombres. The bar was placed under the parts affected (Cajori vol. 1, pages 101 and 385). Chuquet wrote: The above expression in modern notation is . This use of a vinculum appears to be the earliest use of a grouping symbol of any kind mentioned by Cajori. Vinculum above. According to Cajori, the first use of the vinculum above the parts affected was by Frans van Schooten (c. 1615-1660), who "in editing Vieta's collected works, discarded the parentheses and placed a horizontal bar above the parts affected." In Van Schooten's 1646 edition of Vieta, is used to represent B D BD Ball (page 242) says the vinculum was introduced by Francois Vieta (1540-1603) in 1591. This information may be incorrect. Grouping expressed by letters. In the late fifteenth century and in the sixteenth century various writers used letters or words to indicate grouping. The earliest use of such a device mentioned by Cajori (vol. 1, page 385) is the use of the letter v for vniversale by Luca Paciolo (or Pacioli) (c. 1445 - prob. after 1509) in his

Hyperbelzirkel des Frans van Schooten Auf dieser Seite wird eine Simulaton des Hyperbelzirkels von Frans van Schooten (1615-1660) gezeigt. Van Schooten versuchte die bis dahin benutzten Fadenkonstruktionen durch einen stabileren Gelenkmechanismus zu ersetzen, dessen Originalabbildung man in der nebenstehenden Abbildung ansehen kann. Der Punkt A kann in der Simulation frei um C herum bewegt werden, was bei einem realen Gestänge natürlich nicht möglich ist, so dass hier sogar ein Teil des linken Hyperbelastes gezeichnet werden kann, obwohl das mit einem wirklichen Hyperbelzirkel nicht geht. Dies ist der Tribut, den man wegen der Einfachheit des Programmiersystems zahlen muss Reset durch Eintippen von "r" Aufgaben Zeichnen Sie zunächst eine Hyperbel durch Ziehen am Punkt D. Verändern Sie dann die Lage des Punktes F und wiederholen Sie die Zeichnung. Welche Lage hat die Gerade LM bezüglich der Hyperbel? Welche Aufgabe hat die Raute im Gelenkmechanismus?

50. Christiaan Huygens: A Biographical Sketch Christiaan took the courses of the professor of Mathematics, frans van schooten,a friend of the famous French mathematician and philosopher René Descartes http://www.phys.uu.nl/~huygens/bio1_en.htm

Christiaan Huygens: A biographical sketch Family and background Christiaan Huygens was born on 14 April 1629, the second child of the poet and statesman Constantijn Huygens and his wife, Suzanna van Baerle. The Huygens family had close ties to the Court at The Hague, the seat of government of the young republic of the United Provinces, where they occupied important posts in the administration of the Princes of Orange (lieutenants, or stadhouders of the Republic's provinces). His father was one of the best-known poets and authors of the Netherlands. Christiaan thus grew up in an aristocratic and very cultured environment. Schooling at home Together with his older brother, Constantijn, Christiaan was taught by his learned father and by specially appointed tutors. When he was eight, a live-in tutor, a certain Abraham Mirkenius, was hired, whose main task was to teach the brothers Latin, the international language of learning. Their father instructed them in music and arithmetic. This training was so successful that, as father Constantijn related, Christiaan began composing his own music when he was nine, and could then already converse in Latin with his brother. In the following years, he also studied geography, prosody, logic, Greek, French, and Italian, while learning to play the lute, viola, and clavichord. When he was fourteen, Christiaan became interested in drawing and mechanics. He quickly taught himself to copy printed pictures and built little models of devices he read about. “He then spent all his free time in making little windmills and other models, including even a lathe, which in this year [1643] he had managed to put together well enough to enable him to begin making some things with it.” He soon had his own wood-turning lathe. (His new live-in tutor, Hendrik Bruno, had little patience with these hobbies.) The next year, Christiaan began formal lessons in dancing and horseback riding. At this time, too, a mathematics tutor, Jan Jansz. Stampioen was hired for Christiaan and his brother Constantijn.

Christiaan Huygens: biografische schets Afkomst en geboorte Onderwijs aan huis Studie te Leiden Studie te Breda ... Laatste jaren Afkomst en geboorte Christiaan Huygens werd op 14 april 1629 geboren als tweede zoon van de dichter en staatsman Constantijn Huygens en zijn vrouw Suzanna van Baerle. De familie Huygens vormde een dynastie van hoge ambtenaren in dienst van de prinsen van Oranje. Christiaan kwam dus uit een deftig, rijk en zeer cultureel milieu. Onderwijs aan huis Christiaan Huygens kreeg zijn eerste opleiding thuis van zijn vader en van leraren die door zijn vader waren aangesteld. Hij volgde deze lessen samen met zijn oudere broer Constantijn. Toen Christiaan acht was kwam er een huisleraar, een zekere Abraham Mirkenius, wiens belangrijkste taak het was de broers Latijn te leren, de internationale wetenschaps- en cultuurtaal in die tijd. Daarnaast kregen zij van hun vader les in muziek en rekenen. Dit onderwijs had zo veel resultaat dat hij, naar zijn vader verzekert, al op zijn negende begon met zelf te componeren en met zijn broers vrolijk Latijn praatte. In de daarop volgende jaren leerde hij nog geografie, prosodie, spelen op luit, viola da gamba en clavecimbel, logica, Grieks, Frans en Italiaans. Bovendien legde hij zich vanaf zijn veertiende ijverig toe op de mechanica. Zijn vader vertelt hoe Christiaan deze kennis snel praktisch toepaste. Hij kon prenten vaardig natekenen en bouwde modellen van dingen waar hij over las. "Besteedende voorts de snipperingen van syn tydt aen Molenties en andere modellen te maeken, selfs tot een draeybank toe, die hy in dit jaer [1643] soo by een hadde weeten te knusselen, dat hy al eenigh goedt daer op begon te draeyen." Zijn huisleraar Hendrik Bruno (Mirkenius was er inmiddels mee gestopt) kon deze hobbies overigens maar matig waarderen.

Rare Math Books at the University of Michigan The University of Michigan Library started with 3707 volumes (purchased for $5000), including Audubon's "The Birds of America" (1827-38). It offered little mathematics and grew slowly. A major improvement came in 1881 when a complete run of Crelle's Journal was donated. Two faculty made important contributions to the mathematics collection. Alexander Ziwet, who was on the faculty from 1898 to 1925, worked to improve the library and contributed a large collection of his own books. Louis C. Karpinski, on the faculty from 1904 to 1948, gathered many rare volumes for the mathematics collection. Another important influence occurred in 1964 when Mathematical Reviews moved to Ann Arbor. Today the mathematics collection at the University of Michigan is one of the best in the world. The collection of rare mathematics books is outstanding. The titles listed below in chronological order were selected by V. Frederick Rickey, of Bowling Green State University, to show to a history of mathematics course taught at Michigan State University by Dan Chazan on March 11, 1996. We would like to thank Peggy Daub, Head of Special Collections and curator of the mathematics collection at the library for her assistance.

58. Descartes His friendship with Beeckman continued and he also had contact with Mydorge,Hortensius, Huygens and frans van schooten (the elder). http://physics.rug.ac.be/Fysica/Geschiedenis/Mathematicians/Descartes.html

René Descartes Born: 31 March 1596 in La Haye (now Descartes),Touraine, France Died: 11 Feb 1650 in Stockholm, Sweden René Descartes was a philosopher whose work, La géométrie , includes his application of algebra to geometry from which we now have Cartesian geometry. Descartes was educated at the Jesuit college of La Flèche in Anjou. He entered the college at the age of eight years, just a few months after the opening of the college in January 1604. He studied there until 1612, studying classics, logic and traditional Aristotelian philosophy. He also learnt mathematics from the books of Clavius. While in the school his health was poor and he was granted permission to remain in bed until 11 o'clock in the morning, a custom he maintained until the year of his death. School had made Descartes understand how little he knew, the only subject which was satisfactory in his eyes was mathematics. This idea became the foundation for his way of thinking, and was to form the basis for all his works. Descartes spent a while in Paris, apparently keeping very much to himself, then he studied at the University of Poitiers. He received a law degree from Poitiers in 1616 then enlisted in the military school at Breda. In 1618 he started studying mathematics and mechanics under the Dutch scientist Isaac Beeckman, and began to seek a unified science of nature. After two years in Holland he travelled through Europe. Then in 1619 he joined the Bavarian army.
