His name Eudoxus means "honored" or "of good repute" (in [[Greek language|Greek]] εὔδοξος, from ''eu'' "good" and ''doxa'' "opinion, belief, fame"). It is analogous to the Latin name [[wikt:Benedictus|Benedictus]].


Eudoxus's father Aeschines of [[Cnidus]] loved to watch stars at night. Eudoxus first travelled to [[Taranto|Tarentum]] to study with [[Archytas]], from whom he learned [[mathematics]]. While in Italy, Eudoxus visited Sicily, where he studied medicine with [[Philistion of Locri|Philiston]].

Around 387 BC, at the age of 23, he traveled with the physician [[Theomedon]], who according to [[Diogenes Laërtius]] some believed was his lover,<ref>Diogenes Laertius; VIII.87</ref> to Athens to study with the followers of [[Socrates]]. He eventually became the pupil of [[Plato]], with whom he studied for several months, but due to a disagreement they had a falling out. Eudoxus was quite poor and could only afford an apartment at the [[Piraeus]]. To attend Plato's lectures, he walked the seven miles (11&nbsp;km) each direction, each day. Due to his poverty, his friends raised funds sufficient to send him to [[Heliopolis (ancient)|Heliopolis]], Egypt to pursue his study of astronomy and mathematics. He lived there for 16 months. From Egypt, he then traveled north to [[Cyzicus]], located on the south shore of the Sea of Marmara, the [[Propontis]]. He traveled south to the court of [[Mausolus]]. During his travels he gathered many students of his own.

Around 368 BC, Eudoxus returned to Athens with his students. According to some sources, around 367 he assumed headship of the Academy during Plato's period in Syracuse, and taught Aristotle.{{Citation needed|date=September 2010}} He eventually returned to his native Cnidus, where he served in the city assembly. While in Cnidus, he built an observatory and continued writing and lecturing on theology, astronomy and meteorology. He had one son, Aristagoras, and three daughters, Actis, Philtis and Delphis.

Eudoxus is considered by some to be the greatest of [[Classical Greece|classical Greek]] mathematicians, and in all [[Ancient Greece|antiquity]], second only to [[Archimedes]]. He rigorously developed [[Antiphon (person)|Antiphon]]'s [[method of exhaustion]],  a precursor to the [[integral calculus]] which was also used in a masterly way by Archimedes in the following century.  In applying the method, Eudoxus proved such mathematical statements as: areas of circles are to one another as the squares of their radii, volumes of spheres are to one another as the cubes of their radii, the volume of a pyramid is one-third the volume of a [[Prism (geometry)|prism]] with the same base and altitude, and the volume of a cone is one-third that of the corresponding cylinder.<ref name="Kline">Morris Kline, ''Mathematical Thought from Ancient to Modern Times'' Oxford University Press, 1972 pp. 48–50</ref>

Eudoxus introduced the idea of non-quantified  mathematical [[Magnitude (mathematics)|magnitude]] to describe and work with continuous geometrical entities such as lines, angles, areas and volumes, thereby avoiding the use of [[irrational number]]s. In doing so, he reversed a [[Pythagoreanism|Pythagorean]] emphasis on number and arithmetic, focusing instead on geometrical concepts as the basis of rigorous mathematics. Some Pythagoreans, such as Eudoxus' teacher [[Archytas]], had believed that only arithmetic could provide a basis for proofs. Induced by the need to understand and operate with [[Commensurability (mathematics)|incommensurable]] quantities, Eudoxus established what may have been the first deductive organization of mathematics on the basis of explicit [[axiom]]s. The change in focus by Eudoxus stimulated a divide in mathematics which lasted two thousand years. In combination with a Greek intellectual attitude unconcerned with practical problems, there followed a significant retreat from the development of techniques in arithmetic and algebra.<ref name="Kline"></ref>

The Pythagoreans had discovered that the diagonal of a square does not have a common unit of measurement with the sides of the square; this is the famous discovery that the square root of 2 cannot be expressed as the ratio of two integers. This discovery had heralded the existence of incommensurable quantities beyond the integers and rational fractions, but at the same time it threw into question the idea of measurement and calculations in geometry as a whole. For example, Euclid provides an elaborate proof of the Pythagorean theorem (''Elements'' I.47), by using addition of areas and only much later (''Elements'' VI.31) a simpler proof from similar triangles, which relies on ratios of line segments.
 
 
  <li>[http://www.dazhentanwch.com/forum.php?mod=viewthread&tid=2607 http://www.dazhentanwch.com/forum.php?mod=viewthread&tid=2607]</li>
Ancient Greek mathematicians calculated not with quantities and equations as we do today, but instead they used proportionalities to express the relationship between quantities. Thus the ratio of two similar quantities was not just a numerical value, as we think of it today; the ratio of two similar quantities was a primitive relationship between them.
 
 
</ul>
Eudoxus was able to restore confidence in the use of proportionalities by providing an astounding definition for the meaning of the equality between two ratios. This definition of proportion forms the subject of Euclid's Book V.
 
In Definition 5 of Euclid's Book V we read:
 
{{Quote|Magnitudes are said to be in the same ratio, the first to the second and the third to the fourth when, if any equimultiples whatever be taken of the first and third, and any equimultiples whatever of the second and fourth, the former equimultiples alike exceed, are alike equal to, or alike fall short of, the latter equimultiples respectively taken in corresponding order.}}
 
Let us clarify it by using modern-day notation. If we take four quantities: ''a'', ''b'', ''c'', and ''d'', then the first and second have a ratio <math>a/b</math>; similarly the third and fourth have a ratio <math>c/d</math>.
 
Now to say that <math>a/b = c/d</math> we do the following:
For any two arbitrary integers, ''m'' and ''n'', form the equimultiples
''m''·''a'' and ''m''·''c'' of the first and third; likewise form the equimultiples ''n''·''b'' and ''n''·''d'' of the second and fourth.
 
If it happens that ''m''·''a'' > ''n''·''b'', then we must also have ''m''·''c'' > ''n''·''d''.
If it happens that ''m''·''a'' = ''n''·''b'', then we must also have ''m''·''c'' = ''n''·''d''. Finally, if it happens that ''m''·''a'' < ''n''·''b'', then we must also have ''m''·''c'' < ''n''·''d''.
 
Notice that the definition depends on comparing the similar quantities ''m''·''a'' and ''n''·''b'', and the similar quantities ''m''·''c'' and ''n''·''d'', and does not depend on the existence of a common unit of measuring these quantities.
 
The complexity of the definition reflects the deep conceptual and methodological innovation involved. It brings to mind the famous [[parallel postulate|fifth postulate of Euclid]] concerning parallels, which is more extensive and complicated in its wording than the other postulates.
 
The Eudoxian definition of proportionality uses the quantifier, "for every ..." to harness the infinite and the infinitesimal, just as do the modern [[epsilon-delta definition]]s of limit and continuity.
 
Additionally, the [[Archimedean property]] stated as definition 4 of Euclid's book V is originally due not to Archimedes but to Eudoxus.<ref name="Knopp1951">{{Cite book|last=Knopp|first=Konrad|authorlink=Konrad Knopp|title=Theory and Application of Infinite Series|edition=English 2nd|page=7|year=1951|publisher=Blackie & Son, Ltd.|location=London and Glasgow}}</ref>
 
==Astronomy==
In [[ancient Greece]], astronomy was a branch of mathematics; astronomers sought to create geometrical models that could imitate the appearances of celestial motions. Identifying the astronomical work of Eudoxus as a separate category is therefore a modern convenience. Some of Eudoxus' astronomical texts whose names have survived include:
 
* ''Disappearances of the Sun'', possibly on eclipses
* ''Oktaeteris'' (Ὀκταετηρίς), on an eight-year lunisolar cycle of the calendar
* ''Phaenomena'' (Φαινόμενα) and ''Entropon'' (Ἔντροπον), on [[spherical astronomy]], probably based on observations made by Eudoxus in Egypt and Cnidus
* ''On Speeds'', on planetary motions
 
We are fairly well informed about the contents of ''Phaenomena'', for Eudoxus' prose text was the basis for a poem of the same name by [[Aratus]]. [[Hipparchus]] quoted from the text of Eudoxus in his commentary on Aratus.
 
===Eudoxan planetary models===
A general idea of the content of ''On Speeds'' can be gleaned from [[Aristotle|Aristotle's]] ''Metaphysics'' XII, 8, and a commentary by [[Simplicius of Cilicia]] (6th century CE) on ''De caelo'', another work by Aristotle. According to a story reported by Simplicius, Plato posed a question for Greek astronomers: "By the assumption of what uniform and orderly motions can the apparent motions of the planets be accounted for?" (quoted in Lloyd 1970, p.&nbsp;84). Plato proposed that the seemingly chaotic wandering motions of the planets could be explained by combinations of uniform circular motions centered on a spherical Earth, apparently a novel idea in the 4th century.
 
In most modern reconstructions of the Eudoxan model, the Moon is assigned three spheres:
 
* The outermost rotates westward once in 24 hours, explaining rising and setting.
* The second rotates eastward once in a month, explaining the monthly motion of the Moon through the [[zodiac]].
* The third also completes its revolution in a month, but its axis is tilted at a slightly different angle, explaining motion in latitude (deviation from the [[ecliptic]]), and the motion of the [[lunar node]]s.
 
The Sun is also assigned three spheres. The second completes its motion in a year instead of a month. The inclusion of a third sphere implies that Eudoxus mistakenly believed that the Sun had motion in latitude.
 
The five visible planets ([[Venus]], [[Mercury (planet)|Mercury]], [[Mars]], [[Jupiter]], and [[Saturn]]) are assigned four spheres each:
 
* The outermost explains the daily motion.
* The second explains the planet's motion through the zodiac.
* The third and fourth together explain [[apparent retrograde motion|retrogradation]], when a planet appears to slow down, then briefly reverse its motion through the zodiac. By inclining the axes of the two spheres with respect to each other, and rotating them in opposite directions but with equal periods, Eudoxus could make a point on the inner sphere trace out a figure-eight shape, or [[hippopede]].
 
===Importance of Eudoxan system===
[[Callippus]], a Greek astronomer of the 4th century, added seven spheres to Eudoxus' original 27 (in addition to the planetary spheres, Eudoxus included a sphere for the fixed stars). Aristotle described both systems, but insisted on adding "unrolling" spheres between each set of spheres to cancel the motions of the outer set. Aristotle was concerned about the physical nature of the system; without unrollers, the outer motions would be transferred to the inner planets.
 
A major flaw in the Eudoxan system is its inability to explain changes in the brightness of planets as seen from Earth. Because the spheres are concentric, planets will always remain at the same distance from Earth. This problem was pointed out in Antiquity by [[Autolycus of Pitane]]. Astronomers responded by introducing the [[deferent and epicycle]], which caused a planet to vary its distance. However, Eudoxus' importance to [[Greek astronomy]] is considerable, as he was the first to attempt a mathematical explanation of the planets.
 
==Ethics==
[[Aristotle]], in ''[[The Nicomachean Ethics]]''<ref>Largely in Book Ten.</ref> attributes to Eudoxus an argument in favor of [[hedonism]], that is, that pleasure is the ultimate good that activity strives for.  According to Aristotle, Eudoxus put forward the following arguments for this position:
# All things, rational and irrational, aim at pleasure; things aim at what they believe to be good; a good indication of what the chief good is would be the thing that most things aim at.
# Similarly, pleasure's opposite − pain − is universally avoided, which provides additional support for the idea that pleasure is universally considered good.
# People don't seek pleasure as a means to something else, but as an end in its own right.
# Any other good that you can think of would be better if pleasure were added to it, and it is only by good that good can be increased.
# Of all of the things that are good, happiness is peculiar for not being praised, which may show that it is the crowning good.<ref>This particular argument is referenced in Book One.</ref>
