Al-jabr & Other Equations Bibliography Advisor on Mathematics: Ashton Bradley, Victoria University, Wellington, New Zealand. Advisor on Computer Systems: Dr Bruce MacDonald, Electrical & Electronic Engineering Computer Systems, University of Auckland, Auckland, New Zealand. The word "algebra" derives from the Arabic "al-jabr" meaning "the reunion of broken parts." Algebraic concepts were used as early as 1650 B.C. in Egypt and Ancient Babylon, and were brought into Europe by the Arabs. Abu Ja'far Muhammad ibn Musa al-Khwarizmi lived from 780 to 850 Al'Khwarizmi wrote on Hindu-Arabic numerals and was the first to use zero as a place holder in positional base notation. The word algorithm derives from his name. Regarding his treatise Hisab al-jabr w’al-muqabala: Here "al-jabr" means "completion" and is the process of removing negative terms from an equation. For example, using one of al-Khwarizmi's own examples, "al-jabr" transforms x2= 40x - 4x2 into Heisenberg Recalls His Early Thoughts on the Uncertainty Principle. Game theory deals with the analysis of "games" (i.e., situations which involve conflicts of interests). As well as simple games, which can be analysed completely, the theory has applications in "real games" like poker, chess, etc as well as in areas like politics, economics etc.
A strange kind of physical reality, just in the middle between possibility and reality. - Heisenberg.
