It was invisible and penetrating to some materials, but not others. He called the radiation \"X-rays,\" and the phenomenon took over the science world. The very next year, a French physicist named Antoine Henri Becquerel, while studying these rays and trying to link them to phosphorescence,  accidentally stumbled upon a new phenomenon that would ultimately shape the following century."}
