10 unusual facts about Euclid


Defunct townships of Cuyahoga County, Ohio

Euclid Township, named for the ancient Greek mathematician, was formed in 1809 after being surveyed by a team sent out by Moses Cleaveland.

Today, its land is now divided between the cities of Cleveland, Cleveland Heights, East Cleveland, Euclid, Lyndhurst, Richmond Heights, and South Euclid.

John of Damascus

Under the instruction of Cosmas, who also taught John's orphan friend (the future St. Cosmas of Maiuma), John is said to have made great advances in music, astronomy and theology, soon rivalling Pythagoras in arithmetic and Euclid in geometry.

John Opie

He showed a precocious talent for drawing and mathematics; by the age of twelve he had mastered Euclid and opened an evening school for poor children where he taught reading, writing and arithmetic.

Roman Catholic Diocese of Aire

Aire, on the river Adour, the home of St. Philibert, numbered among its bishops during the second half of the sixteenth century François de Foix, Count of Candale, an illustrious mathematician, who translated Euclid and founded a chair of mathematics at the University of Bordeaux.

Sierra Leone Grammar School

Within a year, three of the pupils were able to read the New Testament in Greek and understood Euclid's Elements.

Stourbridge fair

During his time at the University in 1665, Isaac Newton visited the fair and is known to have bought a copy of Euclid's Elements which he used to teach himself mathematics.

Syrian Monastery, Egypt

The manuscripts found in the Syrian monastery inspired intense research on the Syriac language and culture, for until that time, many classical texts from Aristotle, Euclid, Archimedes, Hippocrates and Galen were known to Western scholars only in their thirteenth-century Latin translations.

Theudius

He is only known from Proclus’ commentary to Euclid, where Theudius is said to have had “a reputation for excellence in mathematics as in the rest of philosophy, for he produced admirable "Elements" and made many partial theorems more general”.

Unitary urbanism

The rejection of the standard Euclidean, almost wholly functional, approach to urban architectural design, and


105th and Euclid

Although scores of other African-American property owners were driven out of the 105th and Euclid area and defeated under dubious land-grab tactics, one man, Winston E. Willis, has continued his decades-long struggle to defend his property rights.

Al-Jawhari

Al-Abbās ibn Said al-Jawharī (died circa 860), a mathematician who wrote a commentary on Euclid's Elements

Batty Langley

The eccentric landscape designer, who gave some of his numerous children names like Hiram, Euclid, Vitruvius and Archimedes, even attempted to "improve" Gothic forms by giving them classical proportions.

Convex geometry

Although the first known contributions to convex geometry date back to antiquity and can be traced in the works of Euclid and Archimedes, it became an independent branch of mathematics at the turn of the 19th century, mainly due to the works of Hermann Brunn and Hermann Minkowski in dimensions two and three.

Daniel Santbech

Santbech also studied the subject of gunnery and ballistics as a theoretic discourse as well as for the practical application of war, and utilized the foundations of geometry, with ample references to Euclid and Ptolemy, in order to do so.

Euclid Beach Park

After Euclid Beach Park ceased operation, this carousel was sold and moved to Palace Playland in Old Orchard Beach, Maine, where it operated until 1996.

Hajjaj

Al-Ḥajjāj ibn Yūsuf ibn Maṭar (786-833), translated Euclid's Elements into Arabic

Henry Billingsley

In 1570, Billingsley published his translation of Euclid's Elements The elements of geometrie of the most ancient philosopher Euclide of Megara.

Ignazio Danti

As a boy he learned the rudiments of painting and architecture from his father Giulio, an architect and engineer who studied under Antonio da Sangallo, and his aunt Teodora, who was said to have studied under the painter Perugino and also wrote a commentary on Euclid.

Jesse Norman

His books include The Achievement of Michael Oakeshott (ed), Breaking the Habits of a Lifetime and After Euclid.

John Yonakor

His son Rich was a star athlete in Euclid and went on to play one season for the National Basketball Association's San Antonio Spurs.

Leo the Mathematician

His library can at least partially be reconstructed: Archimedes, Euclid, Plato, Paul of Alexandria, Theon of Alexandria, Proclus, Porphyry, Apollonius of Perga, the lost Mechanics of Quirinus and Marcellus, and possibly Thucydides.

Lucio Russo

Hellenistic scientists, among whom Euclid, Archimedes, Eratosthenes, developed an axiomatic and deductive way of argumentation.

New York State Route 443

Near Euclid Avenue, the route begins to parallel the Normans Kill, crossing under the New York State Thruway (I-87) just east of the latter's exit 23.

Ohio State Route 175

When SR 175 was created in 1923, it ran from Painesville westward along current SR 283 along Lake Erie to the current intersection of SR 175 and SR 283 in Euclid, then turned south along its current alignment until just northwest of its current southern terminus, where it followed Perkins and Columbus Roads southwest to SR 14 in Bedford.

Playfair's axiom

In 1795 John Playfair published a different formulation of Euclid's parallel postulate, which is now called Playfair's axiom; though the axiom bears Playfair's name, he did not create it, but credited others, in particular William Ludlam, with the prior use of it.

Ptolemaic Kingdom

Among other thinkers associated with the Library or other Alexandrian patronage were the mathematician Euclid (ca. 300 BC), the inventor Archimedes (287 BC – c. 212 BC), and the polymath Eratosthenes (ca. 225 BC).

Quadratic equation

Pythagoras and Euclid used a strictly geometric approach, and found a general procedure to solve the quadratic equation.

Regular polyhedron

When these solids were all discovered and by whom is not known, but Theaetetus, (an Athenian), was the first to give a mathematical description of all five (Van der Waerden, 1954), (Euclid, book XIII).

Rosser Reeves

Reeves co-authored The 99 Critical Shots in Pool with Ray Martin to explain both Euclid and Sir Isaac Newtons' geometric proofs.

S/SL programming language

S/SL has been used to implement production commercial compilers for languages such as PL/I, Euclid, Turing, Ada, and COBOL, as well as interpreters, command processors, and domain specific languages of many kinds.

Sicilian Questions

Other important philosophers and thinkers in the Sicilian Questions referred to are, in alphabetical order, Alexander of Aphrodisias, Anaxagoras, Berosus, Crates, Diogenes, Euclid, Al-Farabi, Galen, Al-Ghazali, Al-Hallaj, Ibn Bajja (Avempace) Ibn Sina (Avicenna), Iamblichus, Mellow, Parmenides, Pythagoras, Plato, Socrates, Themistius, Theophrastus, and Zeno of Elea.

Stellar parallax

It is clear from Euclid's geometry that the effect would be undetectable if the stars were far enough away, but for various reasons such gigantic distances involved seemed entirely implausible: it was one of Tycho Brahe's principal objections to Copernican heliocentrism that in order for it to be compatible with the lack of observable stellar parallax, there would have to be an enormous and unlikely void between the orbit of Saturn and the eighth sphere (the fixed stars).

Sturm series

This is almost the same algorithm as Euclid's but the remainder p {i+2} has negative sign.

Theoretical computer science

While formal algorithms have existed for millennia (Euclid's algorithm for determining the greatest common divisor of two numbers is still used in computation), it was not until 1936 that Alan Turing, Alonzo Church and Stephen Kleene formalized the definition of an algorithm in terms of computation.

Vilna Gaon

He also wrote on mathematics, being well versed in the works of Euclid and encouraging his pupil Rabbi Baruch of Shklov to translate the great mathematician's works into Hebrew.
