31 May 2013

chemical engineer and environmental engineering entrepreneur, was born in Memphis, Tennessee, the second of four daughters of Ernest Buford Abron and Bernice Wise Abron, both educators. Abron was educated in Memphis public schools and was a member of the National Honor Society. Abron divorced and had three sons, Frederick, Ernest, and David; she is occasionally credited as Lilia Ann Abron-Robinson.

Abron stayed close to home when she attended LeMoyne College, a historically black college in Memphis, Tennessee. She considered medical school, but she was persuaded by her advisor, Dr. Beuler, to pursue a career in engineering instead. Her decision was a risky one. She did not know of any African Americans with engineering degrees who were actually working as engineers; instead, she once said in an interview, they were often working in post offices. In 1966 Abron received her BS in Chemistry from ...

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 ...
