Some important discoveries made by mistake
X-raysX-rays or x-rays are a type of electromagnetic radiation with short wavelengths. X-rays have brought about a revolutionary change in the diagnosis of diseases in the medical field. The wavelength of x-rays is not seen as much shorter than ordinary light. Due to its short wavelength, it can easily penetrate any material. In 1895, German physicist William Roentgen discovered this ray. 'Cathode rays' had been discovered long before. But researchers still did not know that it was possible to take pictures of the human skeleton using it. In 1895, William Roentgen was experimenting with cathode rays in a glass tube covered with black paper. His aim was to test whether cathode rays were emitted from the glass. At that time, an interesting incident occurred. He saw that a kind of light beam was visible a few feet away from where he was standing! He thought that the light might be coming out from somewhere in the cardboard. But the experiment showed that the rays were not bursting the cardboard, but rather penetrating the cardboard. Seeing the incident, William Roentgen thought: Why can't the rays that can penetrate the cardboard penetrate the human body? That's what he thought. He conducted the experiment with his wife's hand in front of him, and a history-changing event occurred. For the first time, it was possible to create a photographic image of the human skeleton without cutting it. Mrs. Roentgen was shocked to see the picture of her own skeleton and said, "I feel like I'm seeing death before my eyes!" Since the properties of this invisible ray were unknown, William Roentgen named it X-ray. However, many people also call it "radiation rays" after his name. Penicillin The discovery of penicillin is a milestone in modern medicine. It is the first antibiotic discovered in the world. It protects against infections caused by bacteria. Its inventor was physician and bacteriologist Alexander Fleming. There is an interesting story behind the discovery of penicillin.
