Chater 7 Extending the Table, Expnding the Cold War
Chapter 7 Summary
Chapter 7 is about what elements were discovered during World War 2 and the Cold War. It talks about the two guys that put the most elements on the periodic table, Glenn Seaborg and Al Ghiorso, and what they did to get those elements made. It also talks about how Soviet Union scientists were treated under the rule of Vladimir Lenin and Joseph Stalin. Georgy Flyorov won Stalin's loyalty when he warned Stalin of the possibility of a atomic bomb being built in the United States. Stalin awarded him of his very own secluded laboratory a few years afterwards for his loyalty The last story is about how Victor Ninov hijacked the computer data and faked the discover of the 118th element.
