x-rays

X-rays were discovered by accident in 1895 by a German physicist named Wilhelm Roentgen. He was experimenting with electrical currents in a tube when he noticed something strange. A nearby screen started to glow, even though it wasn’t directly connected to the experiment.

Roentgen realized that invisible rays were passing through the tube and lighting up the screen. He called these rays “X-rays” because he didn’t know exactly what they were. He soon found out that X-rays could pass through soft tissues but not bones, making them useful for seeing inside the human body.

The discovery of X-rays quickly changed medicine. Doctors could now take pictures of bones and find injuries or diseases without surgery. This was a huge advancement in healthcare.

Today, X-rays are used all over the world in hospitals and clinics. They are still one of the most important tools in medicine, helping doctors diagnose problems inside the body without having to perform operations.
