Question:
Milos Obilic (Serbian Cyrillic: Milosh Obilitsh, pronounced [miloS obilitc]; died June 15, 1389) was a Serbian knight in the service of Prince Lazar, during the invasion of the Ottoman Empire. He is not mentioned in contemporary sources, but he features prominently in later accounts of the Battle of Kosovo as the assassin of the Ottoman sultan Murad I. Although the assassin remains anonymous in sources until the late 15th century, the dissemination of the story of Murad's assassination in Florentine, Serbian, Ottoman and Greek sources suggests that versions of it circulated widely across the Balkans within half a century after the event. It is not certain whether Obilic actually existed, but Lazar's family - strengthening their political control - "gave birth to the myth of Kosovo", including the story of Obilic.
The hero's first name, Milos, is a Slavic given name recorded from the early Middle Ages among the Bulgarians, Czechs, Poles and Serbs. It is derived from the Slavic root mil-, meaning "merciful" or "dear", which is found in a great number of Slavic given names. Several versions of the hero's surname have been used throughout history. In his History of Montenegro (1754), Vasilije Petrovic wrote of one Milos Obilijevic, and in 1765, the historian Pavle Julinac rendered the surname as Obilic. According to Czech historian Konstantin Josef Jirecek, the surname Obilic and its different renderings are derived from the Serbian words obilan ("plenty of") and obilje ("wealth, abundance"). The surname Kobilic could come from the Slavic word kobila (mare), and means "mare's son", as in Serbian legends the hero is said to have been nursed by one. K. Jirecek connected the surname to two noble families in medieval Ragusa and Trebinje, the Kobilic and Kobiljacic in the 14th and 15th centuries, and noted that they altered their surnames in the 18th century because they considered it "indecent" to be associated with mares. Based on a 1433 document from Ragusan archives, the historian Mihailo Dinic concluded that Milos's original surname was indeed Kobilic (Latin: Cobilich). The rendering Obilic has universally been used by Serbian writers in modern times. The historian Noel Malcolm has proposed that the surname may have been derived from the term kopil, of possible Vlach or Albanian origin, which means "child" or "bastard child". However, a similar word (kopile) exists in the Serbian language and carries the same meaning. Malcolm also hypothesizes that Kobilic might be of Hungarian origin, possibly a transliteration of the Hungarian word kobor lovag (knight-errant). Milos is often referred to in the epic poems as "Milos of Pocerje", and according to local legends, he came from the western Serbian region of Pocerina. In Pocerina there is a spring known as "Miloseva Banja" (Milos's spring) and an old grave that is claimed to be the grave of Milos's sister.

Question:
Rene Descartes (; French: [R@ne dekaRt]; Latinized: Renatus Cartesius; adjectival form: "Cartesian"; 31 March 1596 - 11 February 1650) was a French philosopher, mathematician, and scientist. Dubbed the father of modern western philosophy, much of subsequent Western philosophy is a response to his writings, which are studied closely to this day. A native of the Kingdom of France, he spent about 20 years (1629-49) of his life in the Dutch Republic after serving for a while in the Dutch States Army of Maurice of Nassau, Prince of Orange and the Stadtholder of the United Provinces. He is generally considered one of the most notable intellectual representatives of the Dutch Golden Age.
In The Passions of the Soul written between 1645 and 1646 Descartes discussed the common contemporary belief that the human body contained animal spirits. These animal spirits were believed to be light and roaming fluids circulating rapidly around the nervous system between the brain and the muscles, and served as a metaphor for feelings, like being in high or bad spirit. These animal spirits were believed to affect the human soul, or passions of the soul. Descartes distinguished six basic passions: wonder, love, hatred, desire, joy and sadness. All of these passions, he argued, represented different combinations of the original spirit, and influenced the soul to will or want certain actions. He argued, for example, that fear is a passion that moves the soul to generate a response in the body. In line with his dualist teachings on the separation between the soul and the body, he hypothesized that some part of the brain served as a connector between the soul and the body and singled out the pineal gland as connector. Descartes argued that signals passed from the ear and the eye to the pineal gland, through animal spirits. Thus different motions in the gland cause various animal spirits. He argued that these motions in the pineal gland are based on God's will and that humans are supposed to want and like things that are useful to them. But he also argued that that the animal spirits that moved around the body could distort the commands from the pineal gland, thus humans had to learn how to control their passions. Descartes advanced a theory on automatic bodily reactions to external events which influenced 19th century reflex theory. He argued that external motions such as touch and sound reach the endings of the nerves and affect the animal spirits. Heat from fire affects a spot on the skin and sets in motion a chain of reactions, with the animal spirits reaching the brain through the central nervous system, and in turn animal spirits are sent back to the muscles to move the hand away from the fire. Through this chain of reactions the automatic reactions of the body do not require a thought process. Above all he was among the first scientists who believed that the soul should be subject to scientific investigation. He challenged the views of his contemporaries that the soul was divine, thus religious authorities regarded his books as dangerous. Descartes' writings went on to form the basis for theories on emotions and how cognitive evaluations were translated into affective processes. Descartes believed that the brain resembled a working machine and unlike many of his contemporaries believed that mathematics and mechanics could explain the most complicated processes of the mind. In the 20th century Alan Turing advanced computer science based on mathematical biology as inspired by Descartes. His theories on reflexes also served as the foundation for advanced physiological theories more than 200 years after his death. The Nobel Prize winning physiologist Ivan Pavlov was a great admirer of Descartes.
