Euclid's Elements - Wikipedia, the Free Encyclopedia
Euclid's Elements - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Euclid's_Elements Euclid's Elements From Wikipedia, the free encyclopedia Euclid's Elements (Ancient Greek: Στοιχεῖα Stoicheia) is a mathematical and geometric treatise Elements consisting of 13 books written by the ancient Greek mathematician Euclid in Alexandria c. 300 BC. It is a collection of definitions, postulates (axioms), propositions (theorems and constructions), and mathematical proofs of the propositions. The thirteen books cover Euclidean geometry and the ancient Greek version of elementary number theory. The work also includes an algebraic system that has become known as geometric algebra, which is powerful enough to solve many algebraic problems,[1] including the problem of finding the square root of a number.[2] With the exception of Autolycus' On the Moving Sphere, the Elements is one of the oldest extant Greek mathematical treatises,[3] and it is the oldest extant axiomatic deductive treatment of mathematics. It has proven instrumental in the development of logic and modern science. The name 'Elements' comes from the plural of 'element'. The frontispiece of Sir Henry Billingsley's first According to Proclus the term was used to describe a English version of Euclid's Elements, 1570 theorem that is all-pervading and helps furnishing proofs of many other theorems. The word 'element' is Author Euclid, and translators in the Greek language the same as 'letter'. This Language Ancient Greek, translations suggests that theorems in the Elements should be seen Subject Euclidean geometry, elementary as standing in the same relation to geometry as letters number theory to language. -

E-mail: [email protected] Among regular polygons, the pentagon is considered to be barely used in medieval architectural compositions, due to its odd spatial appearance and difficult method of construction. The pentagon, representing the number five has a rich semantic role in Christian symbolism. Even though the proper way of construction was already invented in the Antiquity, there is no evidence of medieval architects having been aware of this knowledge. Contemporary sources only show approximative construction methods. In the Middle Ages the form has been used in architectural elements such as window traceries, towers and apses. As opposed to the general opinion supposing that this polygon has rarely been used, numerous examples bear record that its application can be considered as rather common. Our paper at- tempts to give an overview of the different methods architects could have used for regular pentagon construction during the Middle Ages, and the ways of applying the form. -
The Geodetic Sciences in Byzantium
The geodetic sciences in Byzantium Dimitrios A. Rossikopoulos Department of Geodesy and Surveying, Aristotle University of Thessaloniki [email protected] Abstract: Many historians of science consider that geodeasia, a term used by Aristotle meaning "surveying", was not particularly flourishing in Byzantium. However, like “lo- gistiki” (practical arithmetic), it has never ceased to be taught, not only at public universi- ties and ecclesiastical schools, as well as by private tutors. Besides that these two fields had to do with problems of daily life, Byzantines considered them necessary prerequisite for someone who wished to study philosophy. So, they did not only confine themselves to copying and saving the ancient texts, but they also wrote new ones, where they were ana- lyzing their empirical discoveries and their technological achievements. This is the subject of this paper, a retrospect of the numerous manuscripts of the Byzantine period that refer to the development of geodesy both in teaching and practices of surveying, as well as to mat- ters relating to the views about the shape of the earth, the cartography, the positioning in travels and generally the sciences of mapping. Keywords: Geodesy, geodesy in Byzantium, history of geodesy, history of surveying, history of mathematics. Περίληψη: Πολλοί ιστορικοί των επιστημών θεωρούν ότι η γεωδαισία, όρος που χρησι- μοποίησε ο Αριστοτέλης για να ορίσει την πρακτική γεωμετρία, την τοπογραφία, δεν είχε ιδιαίτερη άνθιση στο Βυζάντιο. Ωστόσο, όπως και η “λογιστική”, δεν έπαψε ποτέ να διδά- σκεται όχι μόνο στα κοσμικά πανεπιστήμια, αλλά και στις εκκλησιαστικές σχολές, καθώς επίσης και από ιδιώτες δασκάλους. Πέρα από το ότι οι δύο αυτοί κλάδοι είχαν να κάνουν με προβλήματα της καθημερινής ζωής των ανθρώπων, οι βυζαντινοί θεωρούσαν την διδα- σκαλία τους απαραίτητη προϋπόθεση ώστε να μπορεί κανείς να παρακολουθήσει μαθήμα- τα φιλοσοφίας. -

Diophantus of Alexandria
Diophantus of Alexandria Diophantus of Alexandria played a major role in the development of algebra and was a considerable influence on later number theorists. Diophantine analysis, which is closely related to algebraic geometry, has experienced a resurgence of interest in the past half century. Diophantus worked before the introduction of modern algebraic notation, but he moved from rhetorical algebra to syncopated algebra, where abbreviations are used. Prior to Diophantus’ time the steps in solving a problem were written in words and complete sentences, like a piece of prose, or a philosophical argument. Diophantus employed a symbol to represent the unknown quantity in his equations, but as he had only one symbol he could not use more than one unknown at a time. His work, while not a system of symbols, was nevertheless an important step in the right direction. François Viète, influenced by Napier, Descartes and John Wallis, introduced symbolic algebra into Europe in the 16th century when he used letters to represent both constants and variables. Claims that Diophantus lived from about 200 to 284 and spent time at Alexandria are based on detective work in finding clues to the times he flourished in his and others’ writings. Theon of Alexandria quoted Diophantus in 365 and his work was the subject of a commentary written by Theon’s daughter Hypatia at the beginning of the 5th century, which unfortunately is lost. The most details concerning Diophantus’ life are found in the Greek Anthology, compiled by Metrodorus around 500. Diophantus is often referred to as the “father of algebra,” but this is stretching things as many of his methods for solving linear and quadratic equations can be traced back to the Babylonians. -
Medieval Mathematics
Medieval Mathematics The medieval period in Europe, which spanned the centuries from about 400 to almost 1400, was largely an intellectually barren age, but there was significant scholarly activity elsewhere in the world. We would like to examine the contributions of five civilizations to mathematics during this time, four of which are China, India, Arabia, and the Byzantine Empire. Beginning about the year 800 and especially in the thirteenth and fourteenth centuries, the fifth, Western Europe, also made advances that helped to prepare the way for the mathematics of the future. Let us start with China, which began with the Shang dynasty in approximately 1,600 B. C. Archaeological evidence indicates that long before the medieval period, the Chinese had the idea of a positional decimal number system, including symbols for the digits one through nine. Eventually a dot may have been used to represent the absence of a value, but only during the twelfth century A. D. was the system completed by introducing a symbol for zero and treating it as a number. Other features of the Shang period included the use of decimal fractions, a hint of the binary number system, and the oldest known example of a magic square. The most significant book in ancient Chinese mathematical history is entitled The Nine Chapters on the Mathematical Art. It represents the contributions of numerous authors across several centuries and was originally compiled as a single work about 300 B. C. at the same time that Euclid was writing the Elements. However, in 213 B. C., a new emperor ordered the burning of all books written prior to his assumption of power eight years earlier. -

A Short History of Greek Mathematics
Cambridge Library Co ll e C t i o n Books of enduring scholarly value Classics From the Renaissance to the nineteenth century, Latin and Greek were compulsory subjects in almost all European universities, and most early modern scholars published their research and conducted international correspondence in Latin. Latin had continued in use in Western Europe long after the fall of the Roman empire as the lingua franca of the educated classes and of law, diplomacy, religion and university teaching. The flight of Greek scholars to the West after the fall of Constantinople in 1453 gave impetus to the study of ancient Greek literature and the Greek New Testament. Eventually, just as nineteenth-century reforms of university curricula were beginning to erode this ascendancy, developments in textual criticism and linguistic analysis, and new ways of studying ancient societies, especially archaeology, led to renewed enthusiasm for the Classics. This collection offers works of criticism, interpretation and synthesis by the outstanding scholars of the nineteenth century. A Short History of Greek Mathematics James Gow’s Short History of Greek Mathematics (1884) provided the first full account of the subject available in English, and it today remains a clear and thorough guide to early arithmetic and geometry. Beginning with the origins of the numerical system and proceeding through the theorems of Pythagoras, Euclid, Archimedes and many others, the Short History offers in-depth analysis and useful translations of individual texts as well as a broad historical overview of the development of mathematics. Parts I and II concern Greek arithmetic, including the origin of alphabetic numerals and the nomenclature for operations; Part III constitutes a complete history of Greek geometry, from its earliest precursors in Egypt and Babylon through to the innovations of the Ionic, Sophistic, and Academic schools and their followers. -
Welcome to the Complete Pythagoras
Welcome to The Complete Pythagoras A full-text, public domain edition for the generalist & specialist Edited by Patrick Rousell for the World Wide Web. I first came across Kenneth Sylvan Guthrie’s edition of the Complete Pythagoras while researching a book on Leonardo. I had been surfing these deep waters for a while and so the value of Guthrie’s publication was immediately apparent. As Guthrie explains in his own introduction, which is at the beginning of the second book (p 168), he was initially prompted to publish these writings in the 1920’s for fear that this information would become lost. As it is, much of this information has since been published in fairly good modern editions. However, these are still hard to access and there is no current complete collection as presented by Guthrie. The advantage here is that we have a fairly comprehensive collection of works on Pythagoras and the Pythagoreans, translated from the origin- al Greek into English, and presented as a unified, albeit electronic edition. The Complete Pythagoras is a compilation of two books. The first is entitled The Life Of Py- thagoras and contains the four biographies of Pythagoras that have survived from antiquity: that of Iamblichus (280-333 A.D.), Porphry (233-306 A.D.), Photius (ca 820- ca 891 A.D.) and Diogenes Laertius (180 A.D.). The second is entitled Pythagorean Library and is a complete collection of the surviving fragments from the Pythagoreans. The first book was published in 1920, the second a year later, and released together as a bound edition. -
Pythagoras and the Pythagoreans1
Pythagoras and the Pythagoreans1 Historically, the name Pythagoras meansmuchmorethanthe familiar namesake of the famous theorem about right triangles. The philosophy of Pythagoras and his school has become a part of the very fiber of mathematics, physics, and even the western tradition of liberal education, no matter what the discipline. The stamp above depicts a coin issued by Greece on August 20, 1955, to commemorate the 2500th anniversary of the founding of the first school of philosophy by Pythagoras. Pythagorean philosophy was the prime source of inspiration for Plato and Aristotle whose influence on western thought is without question and is immeasurable. 1 c G. Donald Allen, 1999 ° Pythagoras and the Pythagoreans 2 1 Pythagoras and the Pythagoreans Of his life, little is known. Pythagoras (fl 580-500, BC) was born in Samos on the western coast of what is now Turkey. He was reportedly the son of a substantial citizen, Mnesarchos. He met Thales, likely as a young man, who recommended he travel to Egypt. It seems certain that he gained much of his knowledge from the Egyptians, as had Thales before him. He had a reputation of having a wide range of knowledge over many subjects, though to one author as having little wisdom (Her- aclitus) and to another as profoundly wise (Empedocles). Like Thales, there are no extant written works by Pythagoras or the Pythagoreans. Our knowledge about the Pythagoreans comes from others, including Aristotle, Theon of Smyrna, Plato, Herodotus, Philolaus of Tarentum, and others. Samos Miletus Cnidus Pythagoras lived on Samos for many years under the rule of the tyrant Polycrates, who had a tendency to switch alliances in times of conflict — which were frequent. -

To M. Comte we believe society owes the enunciation of this doctrine a doctrine which we may accept without committing ourselves to his theory of 1 the genesis of knowledge, either in its causes or its order." If this principle, held also by Pestalozzi and Froebel, be correct, then it would seem as if the knowledge of the history of a science must be an effectual aid in teaching that science. Be this doctrine true or false, certainly the experience of many instructors establishes the importance 2 of mathematical history in teaching. With the hope of being of some assistance to my fellow-teachers, I have pre- pared this book and have interlined my narrative with occasional remarks and suggestions on methods of teaching. -
Women in Early Pythagoreanism
Women in Early Pythagoreanism Caterina Pellò Faculty of Classics University of Cambridge Clare Hall February 2018 This dissertation is submitted for the degree of Doctor of Philosophy Alla nonna Ninni, che mi ha insegnato a leggere e scrivere Abstract Women in Early Pythagoreanism Caterina Pellò The sixth-century-BCE Pythagorean communities included both male and female members. This thesis focuses on the Pythagorean women and aims to explore what reasons lie behind the prominence of women in Pythagoreanism and what roles women played in early Pythagorean societies and thought. In the first chapter, I analyse the social conditions of women in Southern Italy, where the first Pythagorean communities were founded. In the second chapter, I compare Pythagorean societies with ancient Greek political clubs and religious sects. Compared to mainland Greece, South Italian women enjoyed higher legal and socio-political status. Similarly, religious groups included female initiates, assigning them authoritative roles. Consequently, the fact that the Pythagoreans founded their communities in Croton and further afield, and that in some respects these communities resembled ancient sects helps to explain why they opened their doors to the female gender to begin with. The third chapter discusses Pythagoras’ teachings to and about women. Pythagorean doctrines did not exclusively affect the followers’ way of thinking and public activities, but also their private way of living. Thus, they also regulated key aspects of the female everyday life, such as marriage and motherhood. I argue that the Pythagorean women entered the communities as wives, mothers and daughters. Nonetheless, some of them were able to gain authority over their fellow Pythagoreans and engage in intellectual activities, thus overcoming the female traditional domestic roles.
