The twentieth century was a very eventful one, marked by two world wars - domyhomework.club/ , revolutions and countless scientific and technical achievements. In the natural sciences, countless important discoveries were made, many of which were also significant for the research of Peter Josephus Wilhelmus Debye, such as:
(in chronological order from the beginning of the twentieth century).

DEBYE experienced the First World War in Germany, in Gottingen. Many Europeans emigrated to the States at that time, DEBYE stayed. At the beginning of the Second World War, DEBYE was in Berlin, as director of the Kaiser Wilhelm Institute.
In 1940 he left Germany and Europe, emigrated to the USA and remained there until his death in 1966.
To increase the pressure on wartime Japan, the USA dropped an atomic bom - https://domyhomework.club/science-homework/ - on Hiroshima on 6 August 1945 and on Nagasaki three days later. Millions of people lost their lives and many still suffer from the consequences of nuclear radiation today.
