X-ray of a Mummy's Skull
X-ray of a Mummy's Skull
Spotlight: Ever wonder where x-rays got their mysterious name? When Wilhelm Conrad Roentgen first wrote about them, he called them "a new kind of ray" and designated them as "x" to indicate the unknown. He resisted efforts to name them after himself (they are, however, known as roentgen rays in many languages) but was rewarded in 1901 with the Nobel Prize in Physics, the first one ever awarded. The rays are similar to visible light but with a much shorter wavelength. A huge and immediate boon to medicine, they also caused burns and cancer until it was realized that protective measures were needed. Roentgen first came across x-rays in his laboratory on this date in 1895.

Quote: "When I told my doctor I couldn't afford an operation, he offered to touch up my x-rays."Henny Youngman
