"Arise, my brethren of the revelers' guild,
That I may fill our measure full of wine,
Or e'er the measure of our days be filled." Who was it brought thee here at nightfall, who?
Forth from the harem in this manner, who?
To him who in thy absence burns as fire,
And trembles like hot air, who was it, who? 'Tis but a day we sojourn here below,
And all the gain we get is grief and woe,
Then, leaving our life's riddles all unsolved, And burdened with regrets, we have to go. Khaja! grant one request, and only one

Lord Omar Khayyam Ravenhurst
In the words of Lord Omar, from his introduction to the Principia Discordia: No Discordian Manifesto yet exists. We need at least five. That will generate controversy and confuse Greyface.
My own favorite Holy Name Omar Khayyam Ravenhurst functions that way. It is a walking identity crisis. Anybody can say or do anything in the name of Omar Khayyam Ravenhurst. For better or worse, that never fails to confuse the authorities.
This tradition started in 1960 when I was basic training clerk in Marine Air Base 11. I typed in the Ravenhurst moniker on a training lecture roster, listing him as a truck driver in motor transport serial number 1369697, rank: private.
When Ravenhurst, Omar K., failed to answer the role call somebody called the captain in charge of motor transport to find where Ravenhurst was. Of course, nobody in the motor pool ever heard of any such private.
Motor transport called administration. No Ravenhurst on record there, either. A clerk-typist from administration, Corporal Chadwick, came by to ask me about the mysterious Marine.
Upon returning to his desk, Chadwick completed as IRC card a condensed record which would have to do until Ravenhurst's entire file arrived from his last duty station: Marine Barracks, East British Outer Cambodia.

Links Omar Khayyam was best known in his time as a mathematician and astronomer. His theorems are still studied by mathematicians today. His poetry really only became widely read when Edward FitzGerald collected several quatrains (rubaiyat) that were attributed to Khayyam and translated them into English as the Rubaiyat of Omar Khayyam.
The common view in the West of the Rubaiyat of Omar Khayyam is that it is a collection of sensual love poems. Although some scholars debate this question, many people assert that Omar Khayyam was a Sufi, as well as a poet and mathematician, and his Rubaiyat can only be truly understood using the language of mystical metaphor.

This, it will be noticed, is the method adhered to by Fitzgerald in the translation, with such singularly graceful effect. Under the Sultan Malik Shah, Omar obtained great praise for his proficiency in science, and was loaded with kingly favours; and when Malik Shah determined to reform the calendar, Omar was one of the eight learned men employed upon the work. The result was the Jaláli era (so called from Jalal-u-din, one of the king's names) so highly commended by Gibbon the historian, who says of it, that "this computation of time surpasses the Julian, and approaches the accuracy of the Gregorian style". [Page 19] is said to have at one time exercised that trade; perhaps before the generosity of his friend, Nizám-ul-Mulk, raised him to independence. For some reason, says Fitzgerald, Omar was never popular in his own country, and has therefore been but scantily translated abroad; certain it is that although the Sultan "shower’d favours upon him". His Epicurean audacity of thought and speech caused him to be regarded askance in his own time and country. The whole of the "Up from Earth's Centre through the Seventh Gate

  • By the help of God and with His precious assistance, I say that Algebra is a scientific art. The objects with which it deals are absolute numbers and measurable quantities which, though themselves unknown, are related to "things" which are known, whereby the determination of the unknown quantities is possible. Such a thing is either a quantity or a unique relation, which is only determined by careful examination. What one seaches for in the algebraic art are the relations which lead from the known to the unknown, to discover which is the object of Algebra as stated above. The perfection of this art consists in knowledge of the scientific method by which one determines numerical and geometric unknowns.
    • Treatise on Demonstration of Problems of Algebra I was unable to devote myself to the learning of this algebra and the continued concentration upon it, because of obstacles in the vagaries of time which hindered me; for we have been deprived of all the people of knowledge save for a group, small in number, with many troubles, whose concern in life is to snatch the opportunity, when time is asleep, to devote themselves meanwhile to the investigation and perfection of a science; for the majority of people who imitate philosophers confuse the true with the false, and they do nothing but deceive and pretend knowledge, and they do not use what they know of the sciences except for base and material purposes; and if they see a certain person seeking for the right and preferring the truth, doing his best to refute the false and untrue and leaving aside hypocrisy and deceit, they make a fool of him and mock him.

OMAR AL-KHAYYAM
(1044-1123 C.E.)
Algebra would seem to rank first among the fields to which he contributed. He made an attempt to classify most algebraic equations, including the third degree equations and, in fact, offered solutions for a number of them. This includes geometric solutions of cubic equations and partial geometric solutions of most other equations. His book Maqalat fi al-Jabr wa al-Muqabila is a master- piece on algebra and has great importance in the development of algebra. His remarkable classification of equations is based on the complexity of the equations, as the higher the degree of an equation, the more terms, or combinations of terms, it will contain. Thus, Khayyam recognizes 13 different forms of cubic equatlon. His method of solving equations is largely geometrical and depends upon an ingenious selection of proper conics. He also developed the binomial expansion when the exponent is a positive integer. In fact, he has been considered to be the first to find the binomial theorem and determine binomial coefficients. In geometry, he studied generalities of Euclid and contributed to the theory of parallel lines. The Saljuq Sultan, Malikshah Jalal al-Din, called him to the new observatory at Ray around 1074 and assigned him the task of determining a correct solar calendar. This had become necessary in view of the revenue collections and other administrative matters that were to be performed at different times of the year. Khayyam introduced a calendar that was remarkably accurate, and was named as

The Rubayyat of Omar Khayyam
The character of Safar Timura is loosely based on Omar Khayyam, the ancient Persian poet and astronomer. The son of a tentmaker, Khayyam rose to become the chief astrologer of the sultan, his boyhood friend. Just as Safar, the son of a potter, rose to become the chief wazier of the king, his boyhood friend. Khayyam (A.D. 1044-1123) is best known to us today for his poetry, collected in the remarkable "Rubaiyat Of Omar Khayyam." Of all the many English translations of this work, I prefer Edward Fitzgerald’s. For the edification of my readers, I offer all of Khayyam's remarkable poetry below. If you want to buy it in book form - which I highly reccommend, most editons will cost you less than six dollars. But, more about Omar:
Students of mathematical history also know him as a pioneer in algebra and geometry. Experts say his mathematical discoveries remained unmatched for centuries - to the time of Descartes(A.D. 1596-1650). I first came across "The Rubaiyat" in a bazaar when I was a boy living on the island of Cyprus. Battered and torn, I only paid a few pennies for it. But the first words I read tumbled out like upturned chests of gold: "Awake! for the morning in the bowl of night Has flung the stone that puts the stars to flight. And lo! the hunter of the east has caught The sultan’s turret in a noose of light."

The Time of Omar Khayyam
(Second Half Of Eleventh Century) The most original creations of this time were made in the field of mathematics by Muslims, and the most original genius among those to whom we owe these creations was the Persian Omar Khayyam. It is thus very appropriate to call this time the Time of Omar Khayyam, as Omar is already very well known to a large number of readers. It is probable that his name is more familiar to them than that of any other Muslim scientist. It will thus be relatively easy to remember the title, and I trust that this remembrance will reach to some extent the contents of the following pages. The time of Omar Khayyam was the end of the golden age of Muslim science. A new Muslim sect, that of the Assassins, an off-shoot of the Ismailiya movement, originated in Cairo about 1080.

Statue of Omar Khayyam O mar Khayyam lived between 1044 and 1123 CE and his full name was Ghiyath al-Din Abul Fateh Omar Ibn Ibrahim Khayyam. Omar Khayyam was an outstanding mathematician and astronomer. He was also well known as a poet, philosopher, and physician. In the "History of Western Philosophy", Bertrand Russell remarks that Omar Khayyam was the only man known to him who was both a poet and a mathematician. Omar Khayyam reformed the solar calendar in 1079 CE. His work on Algebra was highly valued throughout Europe in the Middle Ages.Apart from being a scientist, Khayyam was also a well-known poet. In this capacity, he has become more popularly known in the Western world since 1839, when Edward Fitzgerald published an English translation of his Rubaiyat (quatrains). This has since become one of the most popular classics of world literature. It should be appreciated that it is practically impossible to exactly translate any literary work into another language, what to talk of poetry, especially when it involves mystical and philosophical messages of deep complexity. Despite this, the popularity of the translation of Rubaiyat would indicate the wealth of his rich thought.

    Omar Khayyam
    (ca. 1048-1125)
    Persian mathematician, astronomer and poet best known for the Rubaiyat ; also helped reform the solar calendar. Khayyam was an outstanding mathematician and astronomer who wrote several works including Problems of Arithmetic , a book on music and one on algebra before he was 25 years old. An invitation was sent to Khayyam from shah Malik-Shah in 1073 asking Khayyam to go to Esfahan to set up an Observatory in the city. Other leading astronomers were also brought to the Observatory in Esfahan, and for 18 years Khayyam led the scientists and produced work of outstanding quality. It was a period of peace during which the political situation allowed Khayyam the opportunity to devote himself entirely to his scholarly work. During this time, Khayyam led work on compiling astronomical tables, and he also contributed to calendar reform; in 1079 Khayyam measured the length of the year as 365.24219858156 days. Khayyam also solved the cubic equation x3 + 200x = 20x2 + 2000 and he found a positive root of this cube by considering the intersection of a rectangular hyperbola and a circle. An approximate numerical solution was then found by interpolation in trigonometric tables. Khayyam seems to have been the first to conceive a general theory of cubic equations, and perhaps even more remarkable was that Khayyam stated that the solution of this equation requires the use of conic sections and not the ruler and compass method, a result which would not be proven for another 750 years!
