Brief Explanations:
The text begins by stating the central idea that the discovery of X - rays (referred to as "Photography" in the text, likely a misnomer for X - ray discovery) had a significant impact. It then proceeds to detail the events such as the announcement by Professor William Konrad Röntgen, the spread of news through telegraph, and the effects on different places (Vienna, London).
