In 1895, Wilhelm Röntgen conducted a series of experiments involving cathode rays. During these experiments, he noticed that a fluorescent screen in his laboratory started to glow even when it was not directly exposed to the cathode rays. Intrigued, Röntgen realized that a new type of radiation was being emitted, which was later named X-rays—'X' denoting the unknown nature of the rays. His rigorous experimentation confirmed that these rays could penetrate various materials, offering a glimpse into the interior of objects without destruction. Röntgen published his findings in a paper titled 'On a New Kind of Rays,' detailing the properties and potential applications of X-rays.Röntgen's most famous demonstration involved capturing an image of his wife's hand, revealing her ring and bones. This photograph not only illustrated the power of X-rays but also captivated the public's imagination and professional circles. The implications for medicine were vast; X-ray imaging evolved into an essential tool for diagnosing fractures and other injuries, significantly transforming the practice of medicine. Scientific communities worldwide quickly recognized the significance of Röntgen's work, and he received the first Nobel Prize in Physics in 1901 for his extraordinary contributions.
