The RMS Oceanic, operated by the White Star Line, was launched on January 14, 1899, and was one of the most advanced and luxurious liners of its time. Built by Harland and Wolff in Belfast, it was designed to carry 1,710 passengers and 349 crew members. The ship featured lavish first-class accommodations, including a dining room with a piano and organ, a library, and a smoke room. Second and third-class accommodations were also spacious and comfortable, albeit less opulent . The Oceanic departed Belfast for Liverpool on August 26, 1899, where it was received with great fanfare before embarking on its maiden voyage to New York on September 6, 1899 . During World War I, the Oceanic served as an armed merchant cruiser for the Royal Navy until it ran aground and was wrecked off the coast of Foula, Shetland, on September 8, 1914 .

First German Sequence-Controlled Electronic Digital Calculator. Physicist Heinz Billing¹ at the controls of his newest invention, the G1 calculator with Wilhelm Hopmann checking for a loose tube socket. The G1 was a mostly electronic vacuum tube based machine he built by June 1952 at the Arbeitsgruppe Numerische Rechenmaschinen (Working Group on Numerical Calculators) Max Planck Institute for Physics in Göttingen, Germany. Powered by 476 vacuum tubes and 101 mechanical relays consuming 2.4 kW, the 7.2 kHz machine had a slow speed of 3 operations/sec because of the bottleneck imposed by the use of mechanical relay components. It was 32-bit serial calculator with only 36 words stored on an tiny 8″ drum memory spinning at 3000 rpm with 9 read/write heads, the drum storing variables only so the machine had a Harvard architecture. The calculator was controlled entirely by programs on four selectable punched tapes, all the contents of each single track on the drum can be shifted cyclica.

Fake Tree Observation Post of WW1 – Because the front was constantly watched by the enemy, one just couldn’t erect a new tree, because any new tree appearing out of nowhere would have instantly drawn attraction and fire. The fake tree had to replace an existing tree. A dead tree, blasted by a bomb, located ideally near the trenches was chosen. The tree was then photographed and extensively studied, measurements taken and sketches made. A hollow, steel replica was then made in the workshop far behind the lines. At night, under the cover of darkness and artillery fire, the real tree was felled and the fake one installed in its place. The artillery fire also drowned out the noise of the work.
