In 1895, Wilhelm Conrad Röntgen was experimenting with cathode rays when he accidentally discovered X-rays. He noticed that a fluorescent screen in his lab started to glow even though it wasn’t exposed to visible light. Röntgen didn’t initially understand what the rays were, so he called them "X-rays," with "X" representing the unknown. This discovery was pivotal in medical diagnostics, but it's fascinating that it was a complete accident.
It’s amazing how some of the biggest discoveries happen by accident! When Wilhelm Röntgen stumbled upon X-rays, he had no idea how game-changing it would be for medical diagnostics. The mystery of the "X" is still so cool. Science really does surprise us sometimes!
