You will be able to watch a capable scientist work to uncover the mystery of what he suspects is a new kind of radiation, a radiation he eventually calls x-rays. A German scientist, Wilhelm Conrad Roentgen, is the main character in this book. His experimental expertise was the key element in his successful science career. When he saw something unusual as he pursued one of his experiments, he investigated to learn more. Long before Roentgen discovered x-rays many other scientists around the world had seen unusual effects, including fogging of film or electrical changes, effects that they never followed up and that later proved to have resulted from x-rays. So many scientists had the opportunity to discover x-rays. Roentgen was the only one who persisted. He learned much about these new rays, and, even though he had some misgivings about his conclusions about a new kind of rays, accepted the challenge to inform fellow scientists about his discovery. His discovery was the start of many new ideas that changed the world perception of science - and changed the lives of Roentgen and his wife Bertha. Roentgen's story is inspiring and unusual, in that he had to overcome many obstacles on his long journey to become a recognized scientist and teacher. Even after he had earned his doctorate in physics his unusual education path to an advanced degree presented problems. He persisted; his story may inspire the reader not to give up in the pursuit of a goal.
