Career
Euclid was known as the ‘father of geometry’ for a reason. He discovered the subject 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 produced by Euclid.
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. There was a certain case with the Pythagoras equation
for the triangle that Euclid used as an example while writing the ‘Elements’. He stated that ‘the equation was always
true when it was the matter of every right-angle triangle’. The ‘Elements’ sold more copies than the Bible and was
used and printed countless times by mathematicians and publishers, who have used the information, even up to the
20th century. 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’.
He called this the ‘synthetic approach’ that was not based on the logic of trial and error, but on presenting facts from
theory. At a time when knowledge was limited, Euclid even began to take on knowledge based quests on subjects
relating to a different field such as ‘arithmetic and numbers’. He deciphered that it would be humanly impossible to
find out the ‘largest prime number’. He backed this with an example stating that if 1 was added to the largest known
prime number, the product will lead to another prime number. This classic example was the proof of Euclid’s clarity
of thought and precision at his time and age.
Axioms
Euclid stated that axioms were statements that were just believed to be true, but he realized that by blindly following
statements, there would be no point in devising mathematical theories and formulae. He realized that even axioms
had to be backed with solid proofs. Therefore, he started to develop logical evidences that would testify his axioms
and theorems in geometry. In order to further understand these axioms, he divided them into groups of two called
‘postulates’. One group would be called the ‘common notions’ which were agreed statements of science. His
second set of postulates was synonymous with geometry. The first set of notions mentioned statements such as the
“whole is greater than the part” and “things which are equal to the same thing are also equal to one another”. These
are only two of the five statements written by Euclid. The remaining five statements in the second set of postulates
are a little more specific to the subject of Geometry and state theories such as “All right angle are equal” and
“straight lines can be drawn between any two points”.
Euclid’s career flourished as a Mathematician and the ‘Elements’ was eventually translated from Greek to Arabic and
then into English by John Dee in the early periods of 1570. There were more than 1000 editions of the ‘Elements’
printed ever since its inception, which eventually secured a place in early 20th century classrooms as well. There
have been a myriad of Mathematicians who tried to refute and break Euclid’s theories in geometry and mathematics,
but these attempts were always futile. An Italian Mathematician called Girolamo Saccheri tried to outdo the works of
Euclid, but gave up when he couldn’t pinpoint a single flaw in his theories. It would take another century for a new
group of Mathematicians to present new theories in the subject of geometry.
