We used to read the first book of Euclid, but regularly as we reached the dreadful pass we were turned back for a revisal. |

Euclid changed the proofs of several theorems in this book so that they fitted the new definition of proportion given by Eudoxus. |
|
Euclid made repeated use of axioms that he had not stated, without which his arguments are not logically valid. |
|
Using this theorem, Euclid can perform the old Pythagorean proof of Pythagoras' theorem correctly. |

This theorem, also called the infinitude of primes theorem, was proved by Euclid in Proposition IX.20 of the Elements. |
|
So when Euclid described his geometry, many believed it to be the one true geometry. |
|
The unique parallel of Euclid is just a sophism in order to trap ignorant people. |
|
At the time when these papers were written he had received no instruction in mathematics beyond a few books of Euclid and the merest elements of algebra. |
|
Euclid also wrote Phaenomena which is an elementary introduction to mathematical astronomy and gives results on the times stars in certain positions will rise and set. |
|
As well as constructions to divide a line in the golden ratio, Euclid gives applications such as the construction of a regular pentagon, an icosahedron and a dodecahedron. |
|
Although the work is no longer extant, Euclid may have used it as a model for his Elements. |
|
Halley suggested to him that he might devote his considerable talents to the restoration of the work of the early Greek geometers, such as Euclid and Apollonius of Perga. |
|
The first six books contain most of what Euclid delivers about plane geometry. |
|
In other words, to put it into Euclid, or old-fashioned plane geometry, a straight line is not the shortest distance between two points. |
|
They show how Euclid did not fully carry out the project of developing geometry axiomatically. |
|
Combining simplicity with harmony, Tissot's Quadrato collection attracts attention with geometric shapes worthy of Euclid. |
|
|
How could there be a seventh planet, when Euclid had proven that there were only five Platonic solids? |
|
A few years ago, a Bosnian family named Vidovic came to Euclid, Ohio, to escape persecution by Serbs in an embattled region. |
|
He discovered that the sum of the angles of a triangle are two right angles and, when his father found out, he relented and allowed Blaise a copy of Euclid. |
|
The straight line must be one of the earliest curves studied, but Euclid in his Elementsalthough he devotes much study to the straight line, does not consider it a curve. |
|
This is far from an end to the arguments about Euclid the mathematician. |
|
Moore wrote the sections on arithmetic, geometry, trigonometry and cosmography while the sections on algebra, Euclid and navigation were written by Perkins. |
|
Euclid wished to discover whether there existed a simple geometrical proportionality between the apparent size of equal and parallel lines and their distances from the eye. |
|
It is clear that geometers of the 4th century bc were well acquainted with this method, but Euclid provides only syntheses, never analyses, of the problems solved in the Elements. |
|
When Russell was eleven years old, his brother Frank introduced him to the work of Euclid, which transformed his life. |
|
The poet's mathematically inclined brother was named Mamertinus by the Suda but a scholiast in a commentary on Euclid named him Mamercus. |
|
The discoveries of several Greek mathematicians, including Pythagoras, Euclid, and Archimedes, are still used in mathematical teaching today. |
|
It also saw rise to new progress in geometry beyond those classical theories of Euclid, after a period of nearly two thousand years. |
|
The postulates of Euclid are profitably motivated by saying that they lead to a great wealth of geometric facts. |
|
Although Euclid solves more than 100 construction problems in the Elements, many more were posed whose solutions required more than just compass and straightedge. |
|
The probe mounts were dispatched to the Euclid Geometrics laboratory in Kitchener, Ontario, for microprobe analysis. |
|
The Internal Bisector Problem is extremely difficult to prove using the classical theorems of Euclid, though it can be done. |
|
Among the most important figures for me is also Euclid. |
|
Euclid has created an algorithm that has been given its name. |
|
And he is off, to mug up on Euclid, and on the Indian roots of algebra. |
|
The works of Euclid and Archimedes, lost in the West, were translated from Arabic to Latin in Spain. |
|
|
For this reason, he was a major contributor to the study of the Standing Committee on Canadian Heritage on the status of the book industry in Canada and together with Euclid Herie sponsored the work of this Task Force. |
|
For instance, he uses Euclid and ideas that can be traced to Ptolemy in a well-known work on optics, On Perspectives, which is preserved only in Latin. |
|
Once the parallel postulate is introduced Euclid showed that opposite sides of a parallelogram are equal, and so the distance between a pair of parallel lines is a constant. |
|
At the age of eight, Mill began studying Latin, the works of Euclid, and algebra, and was appointed schoolmaster to the younger children of the family. |
