Hippocrates of Chios squared the above left lune, as well as two others, in the fifth century BC Two more squarable lunes were found by T. Clausen in the 19th century (Dunham 1990 attributes these discoveries to Euler in 1771). In the 20th century, N. G. Tschebatorew and A. W.

About indexing Samples Rates Other indexers ... Site map Qualifiers Qualifiers are words or phrases added to a heading or subheading to clarify its meaning or to distinguish among homographs. They may or may not be enclosed in parentheses, as these examples demonstrate: By being added to the heading, they become part of it and are considered during alphabetization. Qualifiers are often used in relation to personal names , where homographs (including surnames and forenames) are common. For example: The date in the first qualifier above includes an question mark to indicate uncertainty about the date. Other abbreviations that are used include b. for "born" and d. for "died." For example: The order of entries for the Hamiltons is due to the fact that question marks and abbreviations signifying birth and death are ignored during alphabetization. Another use is to help identify things or people identified only by a forename or surname in the text. For example: In biographies , qualifiers are often used to specify the relationship between a person and the main subject or a person and others discussed in the text. For example: They may also be used to distinguish between corporate entities having the same name. For example:

64. Dupcubfin.html discrepancy. In addition to Eudoxus' solution, hippocrates of chios alsodeveloped a working solution of the Delian problem. Hippocrates http://www.ms.uky.edu/~carl/ma330/projects/dupcubfin1.html

Duplication of the Cube : Darrell Mattingly, Cateryn Kiernan The ancient Greeks originated numerous mathematical questions, most of which they learned to solve using simple mathematical tools, such as the straight edge and the collapsable compass. Three of these problems persist today, challenging students in contemporary classrooms. This triology of problems, the trisection of a given angle, the squaring of a circle, and the duplication of the cube, have since been proved impossible using exclusively the straight edge and the compass. In the quest to solve these problems using those specific tools, however, mathematicians developed numerous alternate solutions using other mathematical tools. The last problem of the trilogy is the focus of this discussion, and it challenged mathematicians for centuries, due to the restriction of using only the aforementioned tools. Origin of the Problem Proof that NO Platoic Solution Exists for the "Delian" Problem After centuries of mathematicians had worked on this problem, a proof developed that it could not be done using exclusively the straight edge and compass. This proof is based on theorems about the powers of degrees of subfields generated by the x and y coordinates of the side of the cube to be duplicated. Although the desired point can be approximated, it cannot in fact be found based on these theorems.

66. Conic Sections In Ancient Greece A breakthrough of a kind occurred when hippocrates of chios reduced the problem tothe equivalent problem of two mean proportionals , though this formulation http://www.math.rutgers.edu/courses/436/436-s99/Papers1999/schmarge.html

Conic Sections in Ancient Greece Ken Schmarge History of Mathematics Term Paper, Spring 1999 Introduction The knowledge of conic sections can be traced back to Ancient Greece. Menaechmus is credited with the discovery of conic sections around the years 360-350 B.C.; it is reported that he used them in his two solutions to the problem of "doubling the cube". Following the work of Menaechmus, these curves were investigated by Aristaeus and of Euclid. The next major contribution to the growth of conic section theory was made by the great Archimedes. Though he obtained many theorems concerning the conics, it does not appear that he published any work devoted solely to them. Apollonius, on the other hand, is known as the "Great Geometer" on the basis of his text Conic Sections , an eight-"book" (or in modern terms, "chapter") series on the subject. The first four books have come down to us in the original Ancient Greek, but books V-VII are known only from an Arabic translation, while the eighth book has been lost entirely. In the years following Apollonius the Greek geometric tradition started to decline, though there were developments in astronomy, trigonometry, and algebra (Eves, 1990, p. 182). Pappus, who lived about 300 A.D., furthered the study of conic sections somewhat in minor ways. After Pappus, however, conic sections were nearly forgotten for 12 centuries. It was not until the sixteenth century, in part as a consequence of the invention of printing and the resulting dissemination of Apollonius' work, that any significant progress in the theory or applications of conic sections occurred; but when it did occur, in the work of Kepler, it was as part of one of the major advances in the history of science.

Euclid's Elements Book I Proposition 3 To cut off from the greater of two given unequal straight lines a straight line equal to the less. Let AB and C be the two given unequal straight lines, and let AB be the greater of them. It is required to cut off from AB the greater a straight line equal to C the less. Place AD at the point A equal to the straight line C , and describe the circle DEF with center A and radius AD I.2 Post. 3 Now, since the point A is the center of the circle DEF AE equals AD Def.15 But C also equals AD . Therefore each of the straight lines AE and C equals AD , so that AE also equals C C.N.1 Therefore, given the two straight lines AB and C AE has been cut off from AB the greater equal to C the less. Q. E. F. Guide Now it is clear that the purpose of Proposition 2 is to effect the construction in this proposition. Use of Proposition 3 This proposition begins the geometric arithmetic of lines. Explicitly, it allows lines to be subtracted, but it can also be used to compare lines for equality and to add lines. The construction in this proposition is used in Propositions I.5

Hippias (5th cn. BCE.) A Greek sophist of Elis and a contemporary of Socrates. He taught in the towns of Greece, especially at Athens. He had the advantage of a prodigious memory, and was deeply versed in all the learning of his day. He attempted literature in every form which was then extant. He also made the first attempt in the composition of dialogues. In the two Platonic dialogues named after him ( Hippias Major and Hippias Minor ), he is represented as excessively vain and arrogant.

71. Earliest Uses Of Symbols From Geometry of points, lines, and planes by a letter or letters was in vogue among the ancientGreeks and has been traced back to hippocrates of chios (about 440 BC http://members.aol.com/jeff570/geometry.html

Earliest Uses of Symbols from Geometry Last revision: August 26, 2001 Lettering of geometric figures. The designation of points, lines, and planes by a letter or letters was in vogue among the ancient Greeks and has been traced back to Hippocrates of Chios (about 440 B. C.) (Cajori vol. 1, page 420, attributed to Moritz Cantor). Lettering of triangles. Richard Rawlinson in a pamphlet prepared at Oxford sometime between 1655 and 1668 used A, B, C for the sides of a triangle and a, b, c for the opposite angles. In his notation, A was the largest side and C the smallest (Cajori vol. 2, page 162). Leonhard Euler and Thomas Simpson reintroduced this scheme many years later, Euler using it in 1753 in (Cajori vol 2., page 162). Euler used capital letters for the angles. In 1866, Karl Theodor Reye (1838-1919) proposed the plan of using capital letters for points, lower case letters for lines, and lower case Greek letters for planes in a remarkable two-volume work on geometry, Die Geometrie der Lage (Cajori vol. 1, page 423).

Combine the circle with the cross of the axes and a grid of 10 x 10, 50 x 50, 250 x 250, 1250 x 1250 ... squares. The axes define the center of the circle and 4 points of the periphery. 8, 12, 20, 28 ... further points are defined by the following triples beginning with the Holy Triangle: The subsequent triples 1, 2, 3, 4, 5, 6 ... can be derived using two rather simple formulas: triples 1, 3, 5 ... be termed a-b-c (a smaller than b) triples 2, 4, 6 ... be termed A-B-C (A smaller than B) A-B-C follows a-b-c: A = 4b - 3a B = 3b + 4a C = 5c a-b-c follows A-B-C: a = 3B - 4A b = 4B + 3A c = 5C The axes and subsequent triples define 12, 20, 28, 36 ... points of the periphery. If we join them up in turn with lines we obtain a sequence of polygons with 12, 20, 28, 36 ... unequal sides. As the number of sides increases, the polygon slowly converges with the circumscribed circle.

Development of Cometary Thought PART - I Subodh Mahanti Lucius Annaeus Seneca (4B.C.-A.D.65) in Natural Questions ... In thick smoke of human sins, rising every day, every hour, every moment full of stench and horror, before the face of God and becoming gradually so thick as to form a comet, with curled and plaited tresses, which at last is kindled by hot and fiery anger of the supreme Heavenly Judge. Andreas Celichius in The Theologial Reminder of the New Comet (1578) Donald K.Yeomans in Comets : A Chronological History of observations, Science, Myth and Folklore (1991). The development of the scientific understanding about comets has a long and intriguing history. For centuries people (common people and scientists alike) have pondered the appearance of these mysterious apparitions. People's fascination for them, as seneca pointed out, was because they were unusual strange phenomena. They appear rarely. Before the seventeenth century comets were not considered as celestial bodies but as signals at a sinful Earth from God. celichius as quoted above was no doubt expressing the majority view of the comet prevalent in the 16th century. of course, there were opponents, though their number were few. for example Andreas Dudith (1533-89), the Hungarian scholar, countered celichius views by stating that if comets were caused by the sins of the mortals then they would never be absent from the sky.
