Mary Clem
Mary A. Clem (née Mary A. McLaughlin; 19051979) was an American mathematician, and a human computer. She was a staff member at Iowa State University, and was recognized for inventing the “zero check” technique for detecting errors. Biography Clem was born on October 19, 1905 in the small town of Nevada, in Story County, western Iowa. She completed her high school degree and found employment for several years with the Iowa State Highway Commission and Iowa State College as a computing clerk, auditing clerk, and bookkeeper. In 1931, she joined the Mathematics Statistical Service of the Mathematics Department of Iowa State College to work as a human computer under the supervision of George Snedecor. Although she complained that mathematics was her poorest subject in high school, she was fascinated with figures and data. Most of her work was done via punch cards, both creating formulas and cards, and running accuracy checks on them. She invented the “zero check” while wor ...

Atomic Bombings Of Hiroshima And Nagasaki
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict so far. In the final year of World War II, the Allies prepared for a costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 64 Japanese cities. The war in the European theatre concluded when Germany surrendered on 8 May 1945, and the Allies turned their full attention to the Pacific War. By July 1945, the Allies' Manhattan Project had produced two types of atomic bombs: "Fat Man", a plutonium implosion-type nuclear weapon; and "Little Boy", an enriched uranium gun-type fission weapon. The 509th Composite Group of the United States Army Air Forces was trained and equipped with the specialized Silverplate version of the ...

Mathematicians From Iowa
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypatia o ...
