Avempace's wikipedia page is underdeveloped with respect to the amount of information present about him. My goal is to make additions from the information below as well as reword the quotations about his physics contribution in the article so that the material is more easily digestible to a reader who does not have a science background.

Avempace additions
Due to his premature death, Avempace was not able to publish any major works. and not much is known about him.

While not much is known about Avempace, his work has been preserced and can be found in Oxford Bodelian, Krakow, Biblioteka Jagiellonska, Tashkent 2385/92, Escorial, Derenbourg 612, Cairo, Dar al-kutub, Akhlaq 290, Istanbul, Carullah 1279, Ankara, Library of the Faculty of History and Geography, Ismail Saib I 1696 (Taylor 1982)

Biography additions
After the fall, Avempace left Zaragoza. It should be noted, that it is not understood if it was before or after the fall but there is evidence of Avempace looking for shelter from Ibn Tashufin. Under Ibn Tashfin, the Sultan of the Berber Moroccan Almoravid empire, Avempace was imprisoned twice. Despite being unwelcomed, Avempace served as vizier to Ibn Tashfin and remained with the Almoravid empire for the rest of his life until his death in 1136. There has been evidence that brings about the argument that Avempace was murdered by poisoned by peers out of jealousy. However, it is unclear if he really was and who would have done it.

Physics additions
Avempace's biggest contribution to physics is probably his contribution to motion which differs from Aristotle's "law of motion."

In relation to the example of the stone falling through the mediums air and water, Avempace also brings up an example of dust particles to explain his ideas on natural movements. Dust particles are suspended in the air and naturally fall slowly. Despite having enough power to go down, it is still insufficient to displace the air underneath it.

Despite diverging from Aristotle's theory of motion, it appears that Avempace largely agrees with Aristotle's ideas on projectile motion. While there is no known account that lay's out Avempace's ideas over this topic, Avempace gives a short explanation in his commentary of Aristotelian Physics book 8. An interesting piece by Avempace on the theory of projectile motion comes from his example involving a magnet and iron filaments. Magnets present a problem with Aristotle's theory on projectile motion because nothing can be seen physically moving the iron. Avempace, however, believes that a magnet is more complicated than one might think. He presents the idea that the magnet actually moves the air which, in return, moves the iron.

The central theory of the mover and the moved can be seen not only in his work in physics, but also in his work in Philosophy.

Philosophy
In addition to writing on topics such as science and astronomy, there is evidence of Avempace also writing on the topic of Ethics. This gives us an idea of his ideology. We see Avempace profess his view in the works such as Rule of the Solitary, the epistle of the Farewell Message, and the Epistle of Conjunction of Intellect with Man.

From his writings, Avempace has been shown to taken a liking to Plato's contribution to philosophy. Avempace, in particular, takes from Plato's idea of the necessary connection between man and city with a bit of a twist. Plato's idea was to model the perfect city after the human soul. On the other hand, Avempace wanted to use the perfect city as a model for the human soul. Avempace imagines the perfect city as a place that is free of any beliefs or opinions that are in opposition of the truth and where true science reigns supreme. Any man or idea that contradicts these true beliefs are defined as "weeds." Weeds are only to be found in imperfect cities.

Avempace also wrote on the health of a perfect man. He eluded to the idea that the perfect man does not just require physical health, but spiritual health too. Avempace goes into more detail about the soul, which he describes of having both an acquired intellect, as well as an active intellect. The active intellect has no basis coming from the physical world. Acquired intellect, however, is a result of experiences from the material world.

For Avempace, the highest form of spiritual happiness comes from science. Science allows for the truth to be discovered. As a result, in order to be spiritually healthy and, therefore, happy, we must obtain knowledge and search for the truth.

Despite all the ideas that have been presented by Avempace, a central theory was never actually developed. He attributed this to being a very busy man and having his hands in a variety of a fields.
