In 1940 two scientists‚ Howard Florey and Ernest Chain‚ were researching projects in bacteriology looking for ways to enhance or continue with chemistry. Using chemistry they created a brown powder that kept its power for more than a few days. After experimenting they found it to be safe. It was needed right away on the front lines of World

Egyptian writing system is complex but relatively straightforward. The inventory of signs is divided into three major categories‚ namely (1) logograms‚ signs that write out morphemes; (2) phonograms‚ signs that represent one or more sounds); and (3) determinatives‚ signs that denote neither morpheme nor sound but help with the meaning of a group of signs that precede
