| On this day in 1895, physicist Wilhelm Conrad Rontgen (1845-1923) becomes the first person to observe X-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible. Rontgen’s discovery occurred accidentally in his Wurzburg, Germany, lab, where he was testing whether cathode rays could pass through glass when he noticed a glow coming from a nearby chemically coated screen. He dubbed the rays that caused this glow X-rays because of their unknown nature. X-rays are electromagnetic energy waves that act similarly to light rays, but at wavelengths approximately 1,000 times shorter than those of light. Rontgen holed up in his lab and conducted a series of experiments to better understand his discovery. He learned that X-rays penetrate human flesh but not higher-density substances such as bone or lead and that they can be photographed. OOOH EXCITING.

| Herman Cain on Tuesday vehemently denied all sexual harassment allegations against him and said he had no memory of the first accuser to publicly describe claimed misconduct by the Republican presidential hopeful. “They simply didn’t happen. They simply did not happen,” Cain insisted of the accusations of inappropriate sexual behavior, and at least one incident of alleged sexual groping, when he was head of the National Restaurant Association from 1996 to 1999.
