    The Cassini Case In 1997 NASA's Cassini mission to Saturn and its moons led to heated controversies, because it was fueled by plutonium, a substance that could cause serious environmental and health problems if it were released into the atmosphere. Still no major U.S. news outlet in broadcasting or print reported in depth on the risks of the Cassini mission. Westinghouse-owned media like CBS and NBC (also partly owned by General Electric) for example had only reported that children were invited to sign a plaque inside Cassini. Not surprisingly Westinghouse and General Electric are two of the largest corporations with defense contracts and nuclear interests.  |

              Alan Turing b. June 23, 1912, London, England d. June 7, 1954, Wilmslow, Cheshire English mathematician and logician who pioneered in the field of computer theory and who contributed important logical analyses of computer processes. Many mathematicians in the first decades of the 20th century had attempted to eliminate all possible error from mathematics by establishing a formal, or purely algorithmic, procedure for establishing truth. The mathematician Kurt Gödel threw up an obstacle to this effort with his incompleteness theorem. Turing was motivated by Gödel's work to seek an algorithmic method of determining whether any given propositions were undecidable, with the ultimate goal of eliminating them from mathematics. Instead, he proved in his seminal paper "On Computable Numbers, with an Application to the Entscheidungsproblem [Decision Problem]" (1936) that there cannot exist any such universal method of determination and, hence, that mathematics will always contain undecidable propositions. During World War II he served with the Government Code and Cypher School, at Bletchley, Buckinghamshire, where he played a significant role in breaking the codes of the German "  |
