Some days ago the German physicist Wilhelm Röntgen discovered a new advance in medicine that will help to see the inside of people that some bone has been broken , but also the interior other materials like boxes or clothes.

German physicist Wilhelm Röntgen is credited credited as the discoverer of X-rays some days ago. He found the X-rays emanating from Crookes tubes, experimental discharge tubes invented around 1875, by scientists investigating the cathode rays. Röntgen referres to the radiation as "X", to indicate that it’s an unknown type of radiation.

Röntgen was investigating cathode rays from a Crookes tube which he had wrapped in black cardboard so that the visible light from the tube would not interfere, using a fluorescent screen painted with barium platinocyanide. Röntgen realized some invisible rays coming from the tube were passing through the cardboard to make the screen glow. He found they could also pass through books and papers on his desk. Röntgen threw himself into investigating these unknown rays systematically.
