Earliest Uses of Symbols for Trigonometric and Hyperbolic Functions
Last revision: Oct. 1, 2000 Sine. In 1583, Thomas Fincke (or Finck) (1561-1656) used sin. (with a period) in Book 14 of his Geometria rotundi. Cajori writes that "perhaps the first use of abbreviations for the trigonometric lines goes back to ... Finck" (Cajori vol. 2, page 150). In 1624, Edmund Gunter (1581-1626) used sin (without a period) in a drawing representing Gunter's scale (Cajori vol. 2, page 156). However, the symbol does not appear in Gunter's work published the same year. In 1626, Girard designated the sine of A by A, and the cosine of A by a (Smith vol. 2, page 618). In a trigonometry published by Richard Norwood in London in 1631, the author states that "in these examples s stands for sine t for tangent sc for sine complement tc for tangent complement sc for sine complement tc for tangent complement sec for secant " (Smith vol. 2, page 618). In 1632, William Oughtred (1574-1660) used sin (without a period) in Addition vnto the Vse of the Instrvment called the Circles of Proportion (Cajori vol. 1, page 193, and vol. 2, page 158).

22. Earliest Known Uses Of Some Of The Words Of Mathematics (T)
Tangent was introduced by thomas fincke (15611656) in his Thomae FinkiiFlenspurgensis Geometriae rotundi libri XIIII, Basileae Per Sebastianum
http://members.aol.com/jeff570/t.html
Earliest Known Uses of Some of the Words of Mathematics (T)
Last revision: July 28, 2005 TABLE in the sense of "an arrangement of numbers, words, or items of any kind, in a definite and compact form, so as to exhibit some set of facts or relations in a distinct and comprehensive way, for convenience of study, reference, or calculation." The OED’s earliest quotation is from Chaucer’s Canterbury Tales c1386: "Hise tables Tolletanes forth he brought Ful wel corrected." Franklin’s Tale . The Toletan tables were ‘the astronomical tables composed by order of Alphonso X, king of Castile (1252-82), from their being adapted to the city of Toledo.’ (OED) See MULTIPLICATION TABLE. TANGENT (in trigonometry). Bradwardine and other writers used the term umbra versa. Tangent was introduced by Thomas Fincke (1561-1656) in his Thomae Finkii Flenspurgensis Geometriae rotundi libri XIIII, Basileae: Per Sebastianum Henricpetri, 1583. He wrote tangens in Latin. Vieta did not approve of the term tangent because it could be confused with the term in geometry. He used (c. 1593) sinus foecundarum (abridged to foecundus ) and also amsinus and prosinus (Smith vol. 2, page 621).

Past and Future The history of the Zoological Museum, University of Copenhagen By: Torben Wolff Abstract INTRODUCTION museum. The same applies geologically to the circular Cretaceous Paramudra fossil on the floor to the left, now in the Geological Museum, University of Copenhagen. Few museums have had an origin as complicated as that of the Copenhagen Zoological Museum, which mostly owes its fame to its old age and the richness of particularly Arctic and marine animals brought back from a great number of expeditions. 17th CENTURY COLLECTIONS: THE ANATOMICAL PERIOD The 17th century represents a Danish Golden Age of anatomical studies of the organs and their function and of natural history collecting. In addition to his handbook, Anatomicae institutiones His brother-in-law, Ole Worm (1588-1654), was a true polyhistor (Schepelern 1971 . He had studied medicine, botany, etc. at foreign universities for 12 years. Visits to a variety of collections of curios had greatly inspired him to build up his own museum of minerals and soils, dried plants, seeds and fruits, stuffed animals, dried fish and crustaceans, shells and corals together with "artificiosa": archeological specimens, ethnographical artefacts and art objects. Especially the zoological section shows that its founder was aiming at acquiring tangible examples of curiosities mentioned in current publications and was particularly rich in Nordic and Arctic animals, e.g., the skull of a narwhale, a stuffed polar bear and a live great auk.

No single document gives better evidence of the erudition of Sir Thomas Browne , physician, philosopher and encyclopedist than the 1711 Sales Auction Catalogue of the Library of Sir Thomas Browne . It also provides an insight into the proliferation, distribution and availability of books printed throughout 17th century Europe which were purchased in increasing number by the intelligentsia, aristocracy , priest, physician or educated merchant-class. Thomas Browne graduated from the University of Leiden in , having previously studied at the Universities of Montpellier and Padua for his medical degree. Upon his establishment in Norwich as a physician he was able to begin a lifetime's bibliophilia , building a private library, acquiring and no doubt reading many of an estimated 1500 titles. Browne was adept in no less than five contemporary languages (

Expedition 9 Crew Hits the Homestretch

Staff Writer
posted: 4 October 2004 4:30 p.m. ET After nearly six months in space, the crew of the International Space Station (ISS) has entered the homestretch of a mission that ISS managers consider a success despite a few hitches. ISS Expedition 9 commander Gennady Padalka and flight engineer Michael Fincke spent 169 days living and working aboard the ISS since their arrival at the station on April 21. Four spacewalks two of which were unplanned and one spacesuit fix later, they're preparing to return to Earth. "We've accomplished all of our major mission objectives, which is quite remarkable considering we had to add a spacewalk," said Matt Abbott, lead flight director for Expedition 9 at NASA's Johnson Space Center in Houston, during an Oct. 4 mission briefing.

Late Medieval Science at Padova
De Proportionibus Motuum , an incisive reworking of the new kinematics and dynamics originating in Merton College, Oxford. The university library was outstanding for its era and boasted many important new scientific texts. As M. Clagget observes There can be no doubt that Padua was the principal center [in Italy] for the study of English and French natural philosophy Yet even then all did not go well for the professors: in 1411 Biagi Pelacani, one of the exponents of this Padova school of natural philosophy, was fired because the students had deserted his classes, apparently as a consequence of his attempts to extract higher fees from them.
The Sixteenth and Seventeenth Centuries
The Eighteenth Century
In the Eighteenth Century Padova, like many other European Universities had a Bernoulli on its mathematical faculty, in this case Nicholas Bernoulli (1687-1759) (of the second generation of Bernoulli's). Moreover it offered hospitality to a number of other distinguished mathematicians including James Stirling (1692-1770). Iacopo Riccati(1676-1754) was a student of Angeli and Bernoulli.
The Nineteenth Century
Giusto Bellavitis (1803-1880) made a significant contribution to the progress of linear algebra, and was also Magnifico Rettore of the University, a career all the more impressive in view of the fact that he began as a city clerk in nearby Bassano, and received his "laurea"

http://www.pballew.net/arithmet.html
Origins of some Math terms Abscissa is the formal term for the x-axis in a graph. The word is a conjunction of ab (remove) + scindere (tear). Literally then, to tear or cut apart, as the x-axis does to the coordinate plane. The main root is closely related to the Latin root from which we get the word scissor. The mathematical use of the term was apparently coined by Leibniz around 1855. Absolute Value The word absolute is from a variant of absolve and has a meaning related to free from restriction or condition. It seems that the mathematical phrase was first used by Karl Weierstrass in reference to complex numbers. Acute is from the Latin word acus for needle, with derivatives generalizing to anything pointed or sharp. The root persists in the words acupuncture (to treat with needles) and acumen (mentally sharp). An acute angle then, is one which is sharp or pointed. Angle comes from the Latin root angulus , a sharp bend. As with many g sounds the transfer from Latin to the German and English languages switched to a k spelling. The word ankle is from the same root. Algebra comes from an Arabic book that revolutionized how mathematics was done in western cultures. "Al-jebr w'al-mugabalah" written by Abu Ja'far Ben Musa (about 825 AD) who was also known as al-Khowarazmi. The phrase Al-jebr at the start of the title became the word Algebra in western languages. The phrase means "the reunion of broken parts".

http://www.pballew.net/arithme3.html
Math Words, pg 3 Back to Math Words Alphabetical Index Astroid The Astroid is the path of a point on a circle rolling inside another circle with a radius four times as large. The path is sometimes called a hypocycloid of four cusps because it is rolling under (hypo) the larger circle.
The word astroid, which seems to be a different spelling of asteroid, comes from the Greek aster for Star. It seems that the name was applied as late as the 1800's.
The parametric equation for an astroid with a circle of radius r rolling inside a circle of radius 4r is given by x(t)= 3r cos(t)+ r cos(3t), and y(t)= 3r sin(t)-r sin(3t). The figure can also be drawn with the equation x + y = R where R is the radius of the fixed circle, and R/4 is the radius of the rolling circle. This formula was known to Liebniz in 1715. The area of the astroid is 3/2 times the area of the rolling circle. It seems that the name astroid was not used until around 1836. Before that, and even afterward, it has gone by many names including tetracuspid (four cusps), cubocycloid, and paracycle. The length of the astroid is 6R and its area is 3 p R /8. Additional
