  Torpedo (1864) *Giovanni Luppis creates the self-propelled uncderwater missile. *"Damn the torpedoes.... Captain Crayton, go ahead! Joucett, full speed!" Admiral David Farragut, Battle of Mobile Bay, 1864 "Torpedoes are examined on the derk of a target ship after a test firing from HMS Snapper in 1940 The British 7,000-ton steamer Beluchistan sank after this torpedo strike by the German U-boat U-68 in 1942".                         NDespite its notoriety as a naval weapon, the fir modem torpedo was developed in landincked Austa or rather by a retired army officer in what was then the Austrian Empire stretching down to the Adriatic Sea 1864 Giovanni Luppis (1813-1875) presented his idea of using small, unmanned boats carrying explosives against enemy ships to Robert Whitehead (1823 1905), an English engineer producing stram engines for the Austrian Navy Similar devices (spar torpedoes) were also employed in the American Civil War taking place at the same time.

                          X-ray Photography (1895)          Rontgen discovers how to photograph inside the bodies of living things. Introduction                                                           An X-ray is a form of electromagnetic   radiation with a very short wavelength, in the range 10   to 0.01 nanometers. German physicist Wilhelm  Rontgen (1845-1923)  was experimenting with   cathode rays in 1895 when he realized that these   produced another form of radiation when they hit the   glass of the cathode ray tube. He called them X-rays, as   ‘X’ stands for the unknown in mathematics. Rontgen   discovered that X-rays passed through soft materials,   such as paper, card and fabric, and produced   fluorescence and can be used to form images on a   barium-coated photographic plate and discovered the X-   rays passed through the flesh, but not through her   bones, or her ring. Rontgen was awarded the first Noble   prize for physics in 1901.   Information
