Ness Creighton

Egyptian Muslim mathematician, also known as al-Hasib al-Misri, the Egyptian Calculator (or Reckoner). His full name was Abu Kamil Shujaʿ ibn Aslam ibn Muhammad ibn Shuja. Very few biographical details are known concerning Abu Kamil, but his productive peak appears to have been at the end of the ninth century. The year of his birth and the year of his death are known with a decent degree of certainty as he is known to have died before al-Imrani (who died in 955) but to have lived well beyond al-Khwarizmi (who died in 850). A direct successor in the development of algebra to al-Khwarizmi, his texts on algebraic theory helped to form the groundwork for later mathematicians, including al-Karaji. Fibonacci would later adopt his mathematical techniques.

Abu Kamil worked to perfect many of al Khwarizmi s algebraic methods including work with the multiplication and division of algebraic objects and the addition ...

Albuino Azaredo was elected governor of Brazil's state of Espírito Santo (1991–1995). An Afro-Brazilian engineer and successful businessman, Albuino, along with Alceu Collares of the state of Rio Grande do Sul, became one of the first black governors to be elected in Brazil.

Azeredo ran for governor of Espírito Santo as a member of the Democratic Labor Party (PDT).
