| ||1907: Iéna explosion: was a pre-dreadnought battleship built for the French Navy (Marine Nationale). Completed in 1902, the ship was assigned to the Mediterranean Squadron and remained there for the duration of her career, frequently serving as a flagship. She participated in the annual fleet manoeuvres and made many visits to French ports in the Mediterranean. In 1907, while docked for repairs, 120 people died and Iéna was badly damaged by a magazine explosion that was probably caused by the decomposition of old Poudre B propellant. Multiple investigations were launched afterwards and the ensuing scandal forced the Navy Minister to resign. While it was possible to repair her, the ship was not thought worth the time or expense. Her salvaged hulk was used as a gunnery target in 1909 before it was sold for scrap in 1912.

| ||1949: The first time the carbon-14 radioactive dating technique was used. To test the theory the method was used to determine the age of Egyptian artifacts where their age was already known. Willard Frank Libby dated a piece of wood from the Third Dynasty Pharaoh Djoser's tomb that was about 4,700 years old. This age was nearly the same as the half-life of carbon-14, they expected the concentration of carbon-14 would be half that found today. This test was successful. *about.com https://pballew.blogspot.com/2019/03/on-this-day-in-math-march-4.html

| ||1956 An Wang Sells Core Memory Patent to IBM: An Wang sells his patent for ferrite core memory to IBM for $500,000. One of the most important inventions in computer history, ferrite core memory was widely used in digital computers from the mid-1950s until the mid-1970s. The U.S. Patent Office awarded Wang the patent for what he called a pulse transfer controlling device in 1949. Jay Forrester at MIT is considered the inventor of core memory. *CHM https://pballew.blogspot.com/2019/03/on-this-day-in-math-march-4.html Pic search.

| ||1977: The first Freon-cooled Cray-1 supercomputer, costing $19,000,000 , was shipped to Los Alamos Laboratories, NM, and was used to help the defense industry create sophisticated weapons systems. This system had a peak performance of 133 megaflops and used the newest technology, integrated circuits and vector register technology. The Cray-1 looked like no other computer before or since. It was a cylindrical machine 7 feet tall and 9 feet in diameter, weighed 30 tons and required its own electrical substation to provide it with power (an electric bill around $35,000/month). The inventor, Seymour Cray, died 5 Oct 1996 in an auto accident. His innovations included vector register technology, cooling technologies, and magnetic amplifiers.
