||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 good: https://www.google.com/search?q=an+wang
