Extractions: 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).

Extractions: Many say that the Babylonians first developed systems of quadratic equations. This calls for over simplification, because the Babylonians had no concept of an equation. Also, all solutions to Babylonian problems were positive because they were solutions to problems involving lengths. Six Types of Quadratics 3. Roots equal to numbers (square root of x = 2) (6 + square root of 10)(18 - square root of 90) = (108 - square root of 3240 + square root of 3240 - square root of 900) which is 78 Scipione dal Ferro is the first credited with solving cubic equations algebraically, around 1515. However, he could only solve cubic equations with the form He kept this work a secret until 1526 when he revealed it to his student Antonio Fior. Soon, the work was common knowledge around Bologna, where dal Ferro taught at the University of Bologna. Other observations in the field of complex equations were also made, primarily that of Harriot. He observed that if x = b, x = c, x = d then (x - b)(x - c)(x - d) = which allowed more uses for the cubic equations. Many proofs after this followed, including ones which first proved these principles algebraically, instead of geometrically. The further use of algebra supplemented modern mathematics in a very important way.

Extractions: Abraham bar Hiyya was a Spanish Jewish mathematician and astronomer. In the Hebrew of his time 'Ha-Nasi' meant 'the leader' but he is also known by the Latin name Savasorda which comes from his 'job description' showing that he held an official position in the administration in Barcelona. Abraham bar Hiyya is famed for his book Hibbur ha-Meshihah ve-ha-Tishboret (Treatise on Measurement and Calculation), translated into Latin by Plato of Tivoli as Liber embadorum in 1145. This book is the earliest Arab algebra written in Europe. It contains the complete solution of the general quadratic and is the first text in Europe to give such a solution. Rather strangely, however, 1145 was also the year that al-Khwarizmi 's algebra book was translated by Robert of Chester so Abraham bar Hiyya's work was rapidly joined by a second text giving the complete solution to the general quadratic equation. It is interesting to see the areas of mathematics and the mathematicians with which Abraham was familiar. Of course he knew geometry through the works of

Extractions: It is often claimed that the Babylonians (about 400 BC) were the first to solve quadratic equations. This is an over simplification, for the Babylonians had no notion of 'equation'. What they did develop was an algorithmic approach to solving problems which, in our terminology, would give rise to a quadratic equation. The method is essentially one of completing the square. However all Babylonian problems had answers which were positive (more accurately unsigned) quantities since the usual answer was a length. In about 300 BC Euclid developed a geometrical approach which, although later mathematicians used it to solve quadratic equations, amounted to finding a length which in our notation was the root of a quadratic equation. Euclid had no notion of equation, coefficients etc. but worked with purely geometrical quantities. Hindu mathematicians took the Babylonian methods further so that Brahmagupta (598-665 AD) gives an, almost modern, method which admits negative quantities. He also used abbreviations for the unknown, usually the initial letter of a colour was used, and sometimes several different unknowns occur in a single problem. The Arabs did not know about the advances of the Hindus so they had neither negative quantities nor abbreviations for their unknowns. However

Site Map - Search Calendar Controversy A number of controversial issues have been raised as to the correct calendar for determining the Holy Days. This article examines some of these issues. Feast of Unleavened Bread and the Calendar The Feast of Unleavened Bread is a unique Festival. On each of the seven days, one must eat unleavened bread, Leviticus 23:6 Seven days shall ye eat unleavened bread . . . . And in the first day [Nisan 15] there shall be an holy convocation, and in the seventh day [Nisan 21] there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that ONLY may be done of you ( Exodus 12:15-16 What does this mean? Why did God specify that on the two Holy Days of the Feast of Unleavened Bread, that work involving food preparation may be done? God did not repeat this allowance for the other Holy Days, not even the Sabbath. Why not? What is the purpose of this law? Is there proof? Does it make sense? Of all the Holy Days, only Nisan 15 (the first day of the Feast of Unleavened Bread) can ever fall on a Sunday. When it does, which is a rare occasion, Nisan 14 (Passover) falls on the weekly Sabbath. In this case, preparation for Nisan 14 must be made on Friday, Nisan 13, while cleaning up of the Sabbath dishes and any last-minute food preparation for the night to be much observed and the morning of the Holy Day may be done on the Holy Day itself (Sabbath sunset to Sunday sunset). No food preparation for Sunday Nisan 15 may be done on the weekly Sabbath.
