Etymology

Noun

from German X-Strahl "X-ray," from the use of x to represent an unknown value

Word Origin
In 1895, a German scientist, Wilhelm Conrad Röntgen, was experimenting with an electric current passing through a vacuum in a glass tube. He found that a piece of material that glows only when electricity passes through it began to glow even though it was not inside the tube. Röntgen tried to shield the material from the tube. However, he found that the material glowed even when it was shielded by paper or wood. Only a shield of metal stopped the glowing. He guessed that an unknown invisible ray created inside the glass tube was causing this to happen. Since he knew nothing about this mysterious ray, Röntgen called it X-Strahl in German, which translates as X-ray in English. He was using the letter x, which had long been used in mathematics for an unknown value.
