What mathematician wrote thirteen books on geometry in the hellenistic age?

What mathematician wrote thirteen books on geometry in the hellenistic age?

The Elements (Ancient Greek: Στοιχεῖα Stoikheîa) is a mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt c. 300 BC.

Who was Pappus and what contributions did he make to math?

Pappus of Alexandria , (flourished ad 320), the most important mathematical author writing in Greek during the later Roman Empire, known for his Synagoge (“Collection”), a voluminous account of the most important work done in ancient Greek mathematics.

When was Pappus Alexandria born?

Pappus of Alexandria (290 – 350), was a Hellenized Egyptian born in Alexandria. Very little is known about his life, but the written records suggest he was probably a teacher. His main contribution to mathematics was primarily as an encyclopedist.

Who was Hypatia and what contributions did she make to math?

Hypatia became a brilliant public speaker and scholar, and she followed her father on the library’s faculty. There she wrote on mathematics and astronomy. She did work on algebraic equations and conic sections. She invented the astrolabe for ship navigation and devices for measuring the density of fluids.

Who is called the father of geometry?

Euclid, The Father of Geometry.

How do you prove Pappus Theorem?

Theorem 1.1 (Pappus’s hexagon Theorem). Let A,B,C be three points on a straight line and let X,Y,Z be three points on another line. If the lines AY , BZ, CX intersect the lines BX, CY , AZ, respectively then the three points of intersection are collinear.

Was Hypatia real?

Hypatia (born c. 350–370; died 415 AD) was a neoplatonist philosopher, astronomer, and mathematician, who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker in Alexandria where she taught philosophy and astronomy.

How did Hypatia’s work affect us today?

With Hypatia’s work on this important book, she made the concepts easier to understand, thus making the work survive through many centuries. Hypatia was the first woman to have such a profound impact on the survival of early thought in mathematics.

What is Pappus theorem projective geometry?

Pappus’s projective theoremPappus of Alexandria (fl. ad 320) proved that the three points (x, y, z) formed by intersecting the six lines that connect two sets of three collinear points (A, B, C; and D, E, F) are also collinear.

Who was Hypatia’s mom?

Historians don’t know who Hypatia’s mother was, only that she grew up with her father, Theon, who wanted to raise the “perfect human.” To him, this meant someone who was physically and mentally healthy. So Theon taught Hypatia everything he knew about math, as well as how to be an influential speaker.

Is Hypatia Greek or Egyptian?

Hypatia of Alexandria (in Greek: Υπατία) (c. 370 C.E. – 415 C.E.) was a popular Hellenized Egyptian female philosopher, mathematician, astronomer/astrologer, and teacher who lived in Alexandria, in Hellenistic Egypt, just before the advent of the Dark Ages.

Who was Frederico Commandino?

Frederico Commandino was an Italian mathematician who published important translations of works of the Ancient Greek mathematicians. Frederico Commandino’s father was Battista Commandino who was from a leading family in Urbino.

What is a commando?

In the militaries and governments of most countries, commandos are distinctive in that they specialize in unconventional assault on high-value targets. However, the term commando is sometimes used in relation to other units carrying out such tasks, including some civilian police units.

What is Commandino’s theorem in geometry?

Commandino’s theorem, named after Federico Commandino (1509–1575), states that the four medians of a tetrahedron are concurrent at a point S, which divides them in a 3:1 ratio. In a tetrahedron a median is a line segment that connects a vertex with the centroid of the opposite face – that is, the centroid of the opposite triangle.

What was the name of the Finnish commando unit in WW2?

Sissiosasto/5.D is another Finnish Commando unit of the World War Two era. The Detachment was founded on August 20, 1941, under the Lynx Division (5th Division, Finnish VI Corps). It was a self-contained unit for reconnaissance patrolling, sabotage and guerrilla warfare operations behind enemy lines.
