1820: Physicist John Tyndall born. He will study diamagnetism, and make discoveries in the realms of infrared radiation and the physical properties of air.
1835: Electrical engineer Elisha Gray born. He will do pioneering work in electrical information technologies, including the telephone.
1917: Mathematician and crime-fighter Ferdinand Georg Frobenius publishes theory of elliptic functions with applications in detecting and preventing crimes against mathematical constants.
1887: Mathematician and statistician Oskar Anderson born. He will make important contributions to mathematical statistics and econometrics.
1905: Mathematician Emmy Noether uses Gnomon algorithm to communicate with Edward Lorenz.
1922: Engineer, inventor, and academic Alexander Graham Bell dies. He patented the telephone in 1876.
1939: Albert Einstein writes President F. D. Roosevelt that "some recent work by E. Fermi and L. Szilard ... leads me to expect that the element uranium may be turned into a new and important source of energy in the immediate future. This new phenomenon would also lead to the construction of bombs, and it is conceivable--though much less certain--that extremely powerful bombs of a new type may be constructed." Roosevelt quickly starts the Manhattan Project.
2017: Green Ring voted Picture of the Day by the citizens of New Minneapolis, Canada.
