Anaxagoras biography summary rubric

There are no records and references about his parentage. Historians deduce that Anaxagoras was of noble lineage since several of his theories reflect materialism. Anaxagoras was active in Athens as a thinker and teacher around BC. Some of his contemporaries wrote he was rather young at the time and that he held views that were extremely controversial during the era.

Despite, Anaxagoras did find a sizeable following to merit being called a teacher and thinker. Indeed, some historians, including Diogenes Laertius, term Anaxagoras as a progenitor to ancient Athens becoming a seat for thought, study of the human mind and its various actions. The great Athenian administrator, Pericleswas an admirer and ardent follower of Anaxagoras, although much before he assumed power.

But Anaxagoras also paid dearly for his friendship with Pericles. Fearing trial and possible death penalty, Pericles fled to Lampsacus around BC. Pericles, fearing for his master, persuaded Anaxagoras to flee with him. However, these masses cannot fully separate because "in everything there is a part of everything," and each thing appears to be what predominates in it.

Throughout these transformations, the total quantity of any kind of substance remains unchanged. These principles presumably apply not only to particles of qualitatively homogeneous substances, which in the Peripatetic school were called homoiomeries, but also to the opposites of hot and cold, light and darkness, dryness and moisture. Anaxagoras was the first scholar to provide a correct explanation for solar and lunar eclipses and the first to present a clear theory on the phases of the Moon.

He was interested in natural astrology, which refers to the connection between cyclic natural phenomena and the rhythmic movement of celestial bodies. Anticipating modern science by over years, Anaxagoras taught that stars are made of the same matter as our Earth, and that the Sun is a blazing mass. He believed that the Moon is a dark, uninhabited body that receives its light from the Sun, and that comets are wandering stars or bodies.

The idea of differentiation of matter which plays a large role in modern theories of creation of the solar system is present. Anaxagoras also shows an understanding of centrifugal force which again anaxagoras biographies summary rubric the major scientific insights that he possessed. Anaxagoras proposed that the moon shines by reflected light from the "red-hot stone" which was the sun, the first such recorded claim.

Showing great genius he was also then able to take the next step and become the first to explain correctly the reason for eclipses of the sun and moon. His explanation of eclipses of the sun is completely correct but he did spoil his explanation of eclipses of the moon by proposing that in addition to being caused by the shadow of the earth, there were other dark bodies between the earth and the moon which also caused eclipses of the moon.

It is a little unclear why he felt it necessary to postulate the existence of these bodies but it does not detract from this major breakthrough in mathematical astronomy. There is also other evidence to suggest that Anaxagoras had applied geometry to the study of astronomy. As to the structure of matter, Anaxagoras postulated an infinite number of elements, or basic building blocks.

He claimed However, it was the power of nous, or mind, that not only created the world but also was the driving force in its day to day processes. For example [ 2 ] :- The growth of living things, according to Anaxagoras, depends on the power of mind within the organisms that enables them to extract nourishment from surrounding substances.

Aristotle both found much to praise in Anaxagoras's theory of nous. Both Plato and Aristotlehowever, were critical of the fact that the driving force of the nous as proposed by Anaxagoras was not ethical. They wanted nous to always act in the best interests of the world. In fact the nous of Anaxagoras does provide a mechanical explanation of the world after the non-mechanical start when the vortex is produced.
