Chapter 8 Summary


        Kean describes how the two scientists fame was all a mistake. Element 43 was said to be discovered by German chemists and others have claimed to have found it though is was not officially found until 1937 by two Italians, one being Segrè. Segré, despite being pressured by the University of Palermo to name is Panormium and by Naddock to name is Masurium, in the end decides to name the new element technetium,  meaning "artificial". The name suits it since it was, in fact, the first man made element. 
     Segrè's biggest mistake was thinking that there was no transuranic properties about element 93. He also misidentified transuranic Neptunium as a fission product. Kean then begins to talk about Linus Pauling, a brilliant chemist.  Although he is smart, he is also very stubborn. After being proven wrong by a colleague on his triple helix DNA theory, he then published his idea. Some college students (Watson and Crick) discovered that DNA is actually a double helix. The chapter closes with talking about Pauling and what he accomplished after the DNA mishap.
