- Pop Quiz •What mathematical subject did Euclid create????? •Answer: Geometry
- Childhood Euclid was born 300-330 B.C in Alexandria, Egypt. Euclid was kind, fair, and patient. Once, when a boy asked him what’s the point of learning math, Euclid gave him a coin and said, "He must make gain out of what he learns." Another time, he was teaching a king. When the king asked if there was an easier way to learn geometry Euclid said, "There is no royal road to geometry." Then he sent the king to study.
- Adulthood Euclid of Alexandria, was a Greek mathematician, often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I 323–283 BC. His Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century. In the Elements, Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote works on perspective, conic sections, spherical geometry, number theory and rigor. "Euclid" is the anglicized version of the Greek name, meaning "Good Glory".
- Education He attended Plato's Academy in Athens, he received his mathematical training from students of Plato,
- Life as a Mathematician Euclid was known as the ‘Father of Geometry’. He discovered and gave it its value, making it one of the most complex forms of mathematics at the time. After moving to Alexandria, Euclid spent most of his time at the Alexandria library, like many other eminent scholars who spent their time there wisely. The museum was built by Ptolemy, which was central to literature, arts and sciences. It was here that Euclid began developing geometrical ideas, arithmetic’s, theories and irrational numbers into a section called “geometry”. He began developing his theorems and collated it into a colossal treatise called ‘The Elements’. During the course of his vaguely known career, he developed 13 editions to the ‘Elements’ that covered a wide spectrum of subjects ranging from axioms and statements to solid geometry and algorithm concepts. Along with stating these various theories, he began backing these ideas with methods and logical proof that would approve of the statements.
- Facts about the elements of theory The Elements treat the theory of numbers and certain problems in arithmetic on a geometric basis ,and solid geometry, including the five regular polyhedral, or Platonic solids. Primary terms, such as point and line, are defined; unproved assumptions, or postulates, regarding these terms are stated; and a series of statements are then deduced logically from the definitions and postulates. Although Euclid's system no longer satisfies modern requirements of logical rigor, its importance in influencing the direction and method of the development of mathematics is undisputed. that his fifth postulate, equivalent to the statement that one and only one line parallel to a given line can be drawn through a point external to the line, can not be proved from the other postulates; on the contrary, by substituting a different postulate for this parallel postulate two different self-consistent forms of non-Euclidean geometry were deduced.
- Euclid's construction of a regular dodecahedron
- Abraham Lincoln and Euclidean connection At age forty, Abraham Lincoln studied Euclid for training in reasoning, and as a traveling lawyer on horseback, kept a copy of Euclid's Elements in his saddlebag. In his biography of Lincoln, his law partner Billy Herndon tells how late at night Lincoln would lie on the floor studying Euclid's geometry by lamplight. Lincoln's logical speeches and some of his phrases such as "dedicated to the proposition" in the Gettysburg address are attributed to his reading of Euclid.
- Additional Works Along with changing the face of mathematics permanently, Euclid also had a wide range of other works that are still used and referred, to date. These works were pure positions backed with solid proof and followed along the lines and the structure of the ‘Elements’. He went on to study and discover ‘Catoptrics’ which essentially stated the mathematical functions of mirrors. Optics, ratios, data, and conics are some of his other reputed works which are now lost with the mists of time. Euclid successfully completed eight editions or books on the theorems related to conics, which failed to exist through time. He also formed hypotheses and propositions based on Mechanics and Loci. Most of these works were said to have been complementary to each other, and it was suggested that these theories developed actually stemmed from his famous works; the ‘Elements’. He also came up with a set of Euclidian ‘Constructions’ that were basic tools needed to produce geometric constructions.
- Facts about his Occupation His treatise consisted of over 467 propositions to plain and solid geometry, proposes and adages that suggested and agreed to his theories relating to his geometrical ideas writing the ‘Elements’. He stated that ‘the equation was always true when it was the matter of every right-angle triangle’. There was no end to Euclid’s geometry, and he continued to develop theorems on various aspects of math such as ‘prime numbers’ and other, basic ‘arithmetic’. With a series of logical steps developed by Euclid, he believed in making the unknown known to the world. The system that Euclid went on to describe in the ‘Elements’ was commonly known as the only form of geometry the world had witnessed and seen up until the 19th century. However, mathematicians of the modern era developed new theorems and ideas pertaining to geometry and divided the subject to ‘Euclidean Geometry’ and ‘Non-Euclidean Geometry’.
- Death And Legacy The year and reason behind Euclid’s death is unknown to mankind. However, there have been vague appropriations that suggest that he might have perished around 260 B.C. His legacy carried on for 200 centuries after his death and inspired personalities such as Abraham Lincoln along the way. It is said that Lincoln would religiously carry the ‘Elements’ with him wherever he would go, and would often quote the genius of Euclid’s works in his speeches. Even after Euclid’s death, Mathematicians continued to write theorems and his works under his name. In all true sense, at a time when knowledge was inaccessible to a majority of the world’s population, Euclid logically and scientifically developed Mathematical formats of antiquity that are known to the world as “Euclidian Geometry” today.

- Contributions • During the time of Ptolemy I he taught mathematics in Alexandria, Egypt, at the Alexandria library or "Museum", and that he wrote the most enduring mathematical work of all time, the Elements, a thirteen value work. • The great contribution of Euclid was his use of a deductive system for the presentation of mathematics.
