Thomas Alva Edison is issued a patent for a storage-battery electrode and its production. (US No. 1402751)
1927
Fritz Lang’s famous science fiction film Metropolis premieres in theaters. The film took two years to shoot, and it cost more to produce that any other silent film to date. The film’s spectacular special effects, many of which were achieved using the groundbreaking “Schufftan Process“, will earn it a place in history.

The United States Army Signal Corps successfully bounces radar waves off the surface of the Moon for the first time in an operation code-named “Project Diana.” A 180-cycle wave pulse with a 1/4 second duration is beamed from the Evans Signal Laboratories in Belmar, New Jersey. The echo of the beam was received 2.4 seconds later. The event proves that radio waves can penetrate the Earth’s atmosphere. The experiment was supervised by Lieutenant Colonel John H. De Witt, a broadcasting pioneer and amateur astronomer who first conceived the idea in 1940. His own earlier, amateur attempts were unsuccessful.
